'Hey, Marty, are you feeling okay?' Lorraine McFly asked his son, with concern - as the two of them were clearing the dirty dishes from the table.

'Yeah, Mom,' replied Marty, 'I'm fine, why?'

'Well, it's just you're so quiet tonight,' Lorraine replied. 'You're not your usual talkative self tonight.'

'I just have a lot on my mind,' explained Marty, 'that's all.'

'Well, is there anything you want to talk about?' Lorraine asked, gently. 'You know that Dad and I are always there for you.'

'Yeah, Mom, I understand,' insisted Marty. 'I'm not depressed or anything. I just have a lot on my mind, that's all.'

Then Lorraine went to put her arms around Marty. Marty hugged her tightly, as he wept a little.

'Are you sure you're fine, honey?' Lorraine asked, softly. 'It helps to talk about what's on your mind.'

'Maybe later, Mom,' Marty said, quietly - as he wiped his eyes with the back of his hand. 'I just need to be alone for a little while, that's all.'

'Okay, honey, replied Lorraine. 'Just don't be afraid to talk with us, okay? Dad and I really care a lot about you.'

'Yes, Mom,' replied Marty, as he went to his bedroom.

As Marty sat on his bed, he began to refect on all the changes that his time travel experiences had caused. For starters, he parents were a lot more affectionate and loving - and they also had a lot more confidence in themselves. Also, Biff Tannen no longer bullied Marty's father, George. Biff Tannen now ran an auto dealing business, and he was very polite and respectful to the McFlys.

All that was a result of George punching out Biff back in 1955, when Biff had tried to rape Lorraine. All of that was because Marty came back in time, and he had encouraged George to stand up for himself. Of course, Marty had to make his parents fall in love - as to not get erased from existence. Through all that, however, Marty had come to see his parents in a different light - and had a great new respect for them.

The biggest, and perhaps the most important change, was that Marty now has an identical twin brother - named Calvin, no less. On June 20 of 1968, a pair of identical twins named Calvin William McFly and Martin Seamus McFly were born to George and Lorraine McFly. Calvin was the older twin, by two minutes. Calvin and Marty had always been the best of friends.

Even though Marty now had two sets of memories from both timelines, the set of memories from the timeline before Marty travelled back to 1955 still felt more real to him. Marty hoped that, as time passed, his other set of memories would start to feel more real to him. Although, truth to be told, Marty really did not want to lose his memories from the old timeline. Despite all of the drawbacks, Marty wished to retain his memories of his old life - BTT, Before Time Travel, as Marty referred to it.

Despite the wrestling with his memories, though, Marty decidedly did feel a close bond to his twin. Since returning back from 1955, Marty had been pondering over all the memorable moments he had with Calvin - ATT, After Time Travel. He remembered how Calvin had been jealous when Marty first started dating Jennifer Parker. It wasn't that Calvin had a crush on Jennifer, too - but Calvin felt like he was being replaced in his twin's life with a girl. After all, Marty had a girlfriend - and Calvin didn't. Calvin had even resorted to some rather immature tactics to try to break up Marty and Jennifer - which he has since regretted. Fortunately, Calvin had soon learned to accept the presence of a girl in his twin's life - and Calvin had even set up a candlelight dinner for Marty and Jennifer, as sort of a peace offering. Other than the one event, though, Marty and Calvin very rarely fought.

Marty and Calvin were two of the most popular, as well as the nicest, kids in school. However, Marty tended to be the more impulsive of the two - while Calvin was always the sensible one who rarely made rash decisions. Also, Calvin was the more studious of the two - and he actually enjoyed school. Marty, on the other hand, was habitually late for classes - and he didn't get as good grades at school. Mr. Strickland always referred to Marty as being a 'slacker' - and he was always comparing Marty unfavourably to his twin. In fact, the one time that Calvin had been late to school, Mr. Strickland had insisted that he was really Marty pretending to be his twin - because, after all, Calvin was never late for school. As a result, Marty sometimes felt real insecure - and felt as though he was regarded as being the 'bad twin'. Still, Marty loved his twin with all of his heart - and it was hard for him to resent Calvin too much.

Marty had spent a few hours reading through old diaries, and making notes of all the differences between the two timelines. Marty was more impressed by how much had stayed the same, than by how much was different. Marty still met Doc Brown the same way, when he was being bullied by Cliff Tannen and his gang. Marty also managed to set the living room rug on fire at the age of eight - just as predicted to his parents back in 1955. He obviously made a big impression on his parents in 1955, if his twin ended up being named Calvin. Now there was the question of if Marty's parents would ever find out who the mysterious 'Calvin Klein' really was.

'Hey, Marty,' Calvin called out, softly. 'Can I come in?'

'Sure,' replied Marty, 'I was just doing some reflecting.'

'You mean on your old life,' asked Calvin, 'where I didn't exist?'

'Actually,' Marty replied, slowly, 'I was doing more reflecting on this life. My memories really are coming back to me. You and I have had lots of memorable moments together.'

'That's good,' Calvin said, quietly. 'At first I was worried that I lost you forever. I mean, you didn't even remember me when you first came back from 1955.'

'i think it just took a little while for the ripple effect to catch up,' Marty suggested.

'So, how was school?' Doc asked Marty and Calvin, as they were sitting on Doc's bed.

'I saw to it that I made it to school on time,' replied Marty. 'In both timelines, I ended up getting a detention for having four tardies in a row. I have to admit, I was real upset with you for setting all your clocks 25 minutes slow. What was that experiment all about, anyway?'

'I was checking to see if I could keep all the clocks in perfect synchronization with each other,' explained Doc. 'I shouldn't have just taken off without letting you guys know, and I apologize for that. It's just that I was on a run from the Libyan terrorists, and I acted rather rashly. I'm sorry for putting you boys through worry and heartache.'

'I understand, Doc,' Marty said, gently. Then, suddenly becoming worried, Marty asked, 'You don't suppose that the terrorists are still after us, do you? I know I saw the van capsize in the mall parking lot the other night - but what if there are more of them, where they came from?'

'Don't worry, Marty,' Doc said, gently. 'The terrorists have all been captured on Saturday. They hired a hypnotist to drag the information out of one of the terrorists that were in the van. They're not dead, but they have been arrested. So we're safe, now.'

'Phew,' breathed Marty, 'that's a relief. I mean, I have had a nightmare about them last night. I dreamed that you were shot again, in the head - so even the bullet-proof vest couldn't protect you. I don't think I'll be able to go to the mall for awhile. That place give me the creeps, now. That was such a traumatic night for me.'

'So, anyway,' Doc said, trying to change the subject, 'how are you coping with your memories, now? Do either set seem more dominant than the other?'

'I feel like two people who have merged into one,' Marty said, sighing. 'I would say that the memories of this timeline seem a little more dominent, now - while the memories of the old timeline seem more like just the memories of a dream or something. I've been making a list of all the differences and similarities of the two timelines. I'm more impressed by how much had stayed the same, than how much had changed. In a way, I would almost have expected everything to be different - including when I was born, and if I even was born the same. It amazing that my parents were married on the same day - and that they had Dave, Linda, and I at the same times - just that, in this timeline, I also have a twin named Calvin. Heck, I even set the living room rug on fire at the same time in this timeline.'

'I would say that it's the time preservation effect,' Doc explained, 'TPE, for short. I believe that God is, ultimately, in control of everything. That's the best way to explain why so much has stayed the same.'

'Well, that makes sense with me,' Marty replied. 'I was pondering about the events that happened last Friday, and I was amazed at how much they stayed the same. Out of all days of my life, last Friday had probably remained the most alike. The major difference is that the car did not get wrecked, and I had my own truck. My parents also knew about my trip to the lake with Jennifer.'

'It's hard to imagine that I didn't even exist in the other timeline,' Calvin said, sighing. 'So, Marty, you said that the memories of this timeline are more dominent to you?'

'That is correct,' replied Marty. 'I probably won't ever completely lose my memories of my old life - but they are becoming a little more hazy, now. My memories are less clear now, than they were yesterday.'

'So, do you boys have any plans for this week?' Doc asked.

'No, not really,' replied Marty. 'Why?'

'Well,' suggested Doc, 'I was wondering if you boys would like to take a trip to someplace quiet for a few days. That would give the two of you some time to become re-aquainted with each other. Maybe we could take a camping trip to an era several centuries ago, to an area that isn't inhabited with humans?'

'Is that really a good idea, though?' asked Calvin, doubtfully.

'I was thinking that we should take a little break from time travelling,' said Marty. 'Time travel can get real stressful, with worrying about the space-time continuum, and if we might create a paradox.'

'Well, okay, it was just a suggestion,' replied Doc. 'Of course, travelling to the past will always be a bit risky. I suppose you do need a little break from time travel.'

'Well, it's nice of you to think of us, Doc,' Marty said, smiling. 'I was hoping to catch a movie with Jennifer, tonight. Maybe we could watch Teen Wolf, as that movie stars Michael J Fox. I know Jennifer love that actor a lot - and says that he looks like me.'

'He looks like me, too,' Calvin added, smiling. 'Actually, I'm not really into werewolf movies. I like Somewhere In Time. That's a good time travel movie, even if it is a bit sad. Christopher Reeve is a great actor.'

'I like Christopher Reeve better as Superman,' said Marty. 'Anyway, we should probably head home, now. Mom was going to make stir fry tonight, and that's one of my favourite meals.'

'Yeah, I love stir fry, too,' added Calvin. 'Mom is such a great cook, isn't she?'

'Oh, yes,' gushed Marty, 'She's a wonderful.' She's a much better cook in this timeline, Marty added to himself.

'Okay, you boys take care of yourselves,' replied Doc.

Marty and Calvin then embraced Doc, before leaving for home.

oooooooooo

An hour later, Doc had decided to give his old friend, Sabrina Palmer, a call.

'Hello, this is Sabrina Palmer,' said Sabrina, as she answered the phone. 'Who is this?'

'I'm Dr. Brown, your old friend,' replied Doc. 'How are you doing?'

'Oh, I'm doing great, Doc,' gushed Sabrina. 'It's always so nice to hear from you. How are Marty and Calvin doing?'

'Actually, this is what I was calling you about,' explained Doc. He then explained to Sabrina about the time machine, Marty's week in 1955, the trip to 2015, the return to 1955, and the changes in Marty's life. He also explained about the Libyan terrorists, how Marty saw him get shot, and how Marty had nightmares about it.

'I could help out easily enough,' Sabrina said, cheerfully. I have the ability to dreamwalk, so I'll see to it that the twins have pleasent dreams tonight.'

'Thank you so much, Sabrina,' Doc replied. 'That will really help Marty out a lot.'

October 29, 1985
12:20 AM PST

Sabrina had popped in a tape of psychedelic tunes. Then she set the timer so that the tape wouldn't start for ten minutes. The music would set the mood for the dream she was about to give Marty and Calvin. The had also lit up some incense, which would provide a very pleasent scent. She would have to drag Marty and Calvin into her dream. In her mind, she had conjured up a bean bag chair big enough to fit both Marty and Calvin. Then she had conjured up three lava lamps. Then she also conjured up some psychedelic swirls to spin all around Marty and Calvin. Transforming herself into the form of a colourful bird, she began to dreamwalk.

oooooooooo

Marty was panting and sweating heavily, as he was running away from the terrorists that were persuing him. He had just seen the terrorists shoot Doc in the head, and he knew that he would be their next target. Suddenly, out of nowhere, he saw a very beautiful bird. Marty began to relax a bit, as he slowly followed the bird through a door. He then smelled the sweet smell of incense, and he flopped fown on the bean bag chair. For some reason, he felt very safe from the terrorists. He then saw Calvin enter from the other side of the room. Calvin then flopped onto the bean bag chair with Marty.

Suddenly, I Had Too Much To Dream by The Electric Prunes was blasting through the walls. Marty smiled, as he really enjoyed that song a lot. Marty put his arm around Calvin, and smiled at him. Calvin had smiled back.

'How did you get here?' Calvin whispered.

'I was running away from some terrorists,' explained Marty. 'I now know that the terrorists weren't real though. They were just figments of my imagination. Doc will be alright.'

'I was in class, taking a test,' explained Calvin, 'then I suddenly realized that I was naked, and I was desperately trying to cover myself up. Then I found myself wearing these footed fleece pajamas, as a very beautiful bird appeared in front of me. I just followed the bird, and then I landed in this room.'

Marty looked down at his body, and he realized that he was wearing footed fleece pajamas, too. Marty felt so comfortable and relaxed. He just lay back and relaxed, as he enjoyed the music and watched the lava lamps. Then Nothin' Yet by The Blues Magoos began to play. Marty smiled, as he really enjoyed the song. The music, the scent in incense, the motion from the lava lamps, and the psychedelic swirls were very soothing to Marty. He felt real serene.

After a little while, a plate of brownies had appeared in front of Marty and Calvin. As Marty lifted up a brownie, and put it in his mouth, he was amazed by how gooey and delicious the brownie had tasted. Marty felt like he was in heaven.

oooooooooo

Sabrina smiled, as he flew above Marty and Calvin and saw how happy and relaxed they were. Mission accomplished, Sabrina thought to herself. She felt so bad that Marty was still having nightmares about being chased by terrorists.

Although, she personally didn't understand why Doc felt the need to take a deal with terrorists. Doc could have just called her, and she would have been able to figure out a safer alternative to plutonium. Doc did explain to her about how he first saw Marty in 1955, and how Marty had written him that letter about being shot by terrorists. He figured that he had to ensure that Marty would travel to 1955, as to avoid creating a paradox, Still, Sabrina figured there could have been other ways to ensure that Marty travelled to 1955. He didn't have to re-enact the scene of what happened in the 'original' timeline. This also raised the question of why Doc from the original timeline had felt the need to make a deal with terrorists.

At any rate, Sabrina had looked at her work with pride. She was worried that she might have some difficulty with calming Marty. He must have known that the chase from the terrorists wasn't real. Sabrina knew, from experience, that when she visits people in their dreams - they are usually more lucid then they are during regular dreams, even if they didn't usually know that they were dreaming.

oooooooooo

'Calvin, I had such an unusual dream last night,' Marty told his twin. 'I dreamed that I was running away from terrorists, then I saw this really beautiful bird. I followed the bird, then I found myself in a room. The room had a bean bag chair - and there were lava lamps, incense, and psychedelic music. We were both wearing fleece footed pajamas.'

'Great Scott!' gasped Calvin, mimicking Doc. 'I had the same exact dream as you did, expect that I wasn't being chased by terrorists. Instead, I was taking a test in class, and I found out that I was naked. I felt so embarrassed. I was desperately trying to cover myself, when I saw this beautiful bird in front of me.'

'I wonder who that beautiful bird was,' Marty said, smiling. 'It might have been our guardian angel. It was nice of the bird to rescue us from our nightmares. That has got to be the most pleasent dream that I've had, in ages.'

'Well, anyway,' Calvin said, sighing, 'I suppose we'd better get ready for school, now. I'm sure you don't want to get a tardy today.'

'No, absolutely not,' replied Marty, smiling.

oooooooooo

'Hey, you boys are all smily this morning,' Lorraine said, impressed.

'We woke up from a very pleasent dream,' Marty replied, smiling.

'That's nice to hear,' Lorraine said, throwing her arms around Marty.

Marty just smiled at his mother. He hadn't told his parents about Doc getting involved with the Libyan terrorists. Not only would his parents become very concerned about Doc, but Marty and Calvin would have to answer a lot of tricky questions about why Doc felt that he needed to make a deal with terrorists. Doc had believed the less people who knew about the time machine, the better. After all, Calvin and especially Marty had experienced first hand how risky time travel can be.

'So, how has your day been, today?' Doc asked Marty and Calvin, smiling.

'My day has been pretty good,' Marty replied. 'This is the second day in a row that I went to school on time. Needles did give me a bit of a hard time for not racing him the other day, but I just ignored him. I mean, there really is no reason to value his opinion, anyway.'

'Now you're getting it, Marty,' Calvin exclaimed. 'I guess taking that trip to 2015 really caused you to see the importance of maintaining your self-control, eh?'

'Yeah,' replied Marty, blushing a bit, 'seeing your own future can really change your outlook on life a lot. I mean, I want to provide a happy life for my future kids, and I don't want to end up in Hilldale. I suppose I could try to find a way to warn others that Hilldale will not be all that it's cracked up to be.'

'No, don't do that, Marty,' protested Doc. 'We must not let other people know too much about the future. It's something that people will have to find out, in the natural course of time.'

'Yeah, you're right, Doc,' Marty said, sighing. 'Anyway, it's not as drastic as when I tried to warn you in 1955 about how you would be shot by terrorists. Gee, I am so happy you decided to tape that letter back together, and read it. I was so grief-stricken when I thought you were shot dead.'

'Hey, Doc, can you do us a little favour?' asked Calvin. 'Please, in the future, do not make anymore deals with terrorists, okay? I've been real concerned about you the past few days. Believe me, Doc, it just isn't worth the risk.'

'I had a nightmare last night that you were shot in the head,' explained Marty, 'and that the terrorists were about to shoot me. Then this beautiful little bird appeared out of nowhere. I followed the bird into a room, and I was suddenly in psychedelic heaven. I then felt serene, as if the terrorists were no longer a threat.'

'I had almost the same dream, too,' added Calvin, 'except that I wasn't running away from terrorists. I was at school, taking a test, and I suddenly realized I was naked.'

'I wonder if that bird was our guardian angel,' Marty said, smiling.

'I'm pretty sure it was,' replied Doc, smiling at Marty and Calvin. 'I promise that I won't make anymore deals with terrorists. It was a rather foolish thing to do - and I'm not sure what possessed the me of the original timeline to do so.'

'Anyway, enough about terrorists,' Calvin said, smiling. 'So, Doc, have you thought anything about that other mystery of the universe? You know, women?'

'No, not really,' replied Doc. 'I guess I don't really care anymore if I ever get married. I mean, I'm too old to have children.'

'Oh, Doc, don't be so negative,' Marty chided, gently.

'I'm not being negative,' protested Doc. 'I'm just being realistic. I really don't need a woman in my life to be happy. I understand how you and Jennifer are in love with each other - but I just don't reckon that romance is really in the cards for me. For me, my inventions are my first love. My inventions are my pride and joy. Am I making any sense to you. I guess I'm not, am I.'

'Well, I do understand, somewhat,' Marty said, slowly. 'I guess you're as passionate about your inventions, as I am about my music. I'm sure you feel the same way when you've successfully created an invention that works, as I do when I finish writing a song. Is that what you mean, Doc?'

'Precisely,' Doc replied, smiling. 'You have to remember that what makes you happy, may not necessarily make other people happy.'

'A have a perfect example to illustrate Doc's point,' added Calvin. 'You know how our cousin, Tracey, finds enjoyment in being tickled on the soles of her feet? I know you don't - and neither do I.'

Marty cringed at the thought of being tickled on the soles of his feet. Marty loved being tickled most everywhere, but the soles of his feet were just way too ticklish.

'I see you're cringing, just thinking about it,' Calvin teased, playfully. 'Another example would be how Dad loves liver, but you and I can't stand it.'

Just the very mention of liver made Marty want to gag. That had to be the most nasty thing Marty had ever tasted. He's rather eat ants than eat liver.

'You getting the point, now, Marty?' Calvin asking, with a playful smile.

'Yes, Calvin, I do,' Marty said, sighing. 'I guess it's a case of different strokes for different folks, eh?'

'Thank you, Calvin,' Doc said, smiling gratefully at Calvin, 'for helping me make my point. Sure, I think it would be great to have a woman in my life - but I'm not all broken up about it, just because I don't. It's all about keeping things in perspective, know what I mean?'

'Okay, I get it, Doc,' Marty said, smiling. 'So what about that mind-reading thing you were working on in 1955? Have you ever gotten it to work successfully.'

'I have to admit, I kind of abandoned that project,' Doc said, blushing. 'I guess I could try working on it, again.'

'Yeah, because, you see, Doc,' Marty explained, 'I think the mind reading device did work to some extent. It's just that there were a few bugs in it, so it wasn't working the way you expected it to.'

'Oh?' Doc asked, suddenly curious. 'Care to explain what you mean?'

'Okay, Doc, here goes.' Marty took a deep breath, and continued, 'You see, the 'great distance', as your first guess was, was how I had travelled from 1985. The 'subscription to the Saturday Evening Post', which was your second guess, was the newspaper I looked at earlier, to check what year it was. The 'donations' you had for your third guess was the Save the Clock Tower lady that Jennifer and I had encountered last Friday, prior to travelling to 1955. The 'Coast Gaurd' as your fourth guess was how my maternal grandmother thought that I was a sailor, but I told her that I was a coast gaurd.'

'Great Scott!' exclaimed Doc. 'I guess it was working somewhat - and, all along, I didn't even realize it. That was very perceptive of you, Marty.'

'Well, it was kind of hard to forget that incident,' Marty said, gently. 'I mean, when I first came to your house to seek help - the first thing you did was put the suction cup on my forehead, and attempt to read my mind.'

Marty and Doc immediately burst out laughing at the memory. Even Calvin smiled a bit - although he, of course, didn't witness the event.

'Ah, memories,' sighed Doc, smiling widely.

'Anyway, I suppose Marty and I should start heading home, now,' Calvin said, smiling. 'Mom is making fried chicken and stuffing tonight, and we don't want to miss it.'

'Right,' added Marty, smiling in agreement. 'Mom is a great cook, and I really do enjoy her cooking a lot.'

'Well, you boys go have a good dinner, then,' Doc said, smiling.

Doc then hugged Marty and Calvin, before they left for home.

7:30 PM PST

'So what's up with you, Marty?' asked Jennifer, as the two of them were sitting on the swing by Jennifer's house.

'What do you mean, Jennifer?' asked Marty, somewhat defensively. 'What are you talking about?'

'Well, you seem a little, uh, different,' insisted Jennifer. 'I suspect there is something you aren't telling me, Marty. You're not seeing another girl, are you?'

'No, of course not, Jennifer!' protested Marty. 'Don't be silly! You're the girl of my dreams. What would make you think otherwise?'

'Well, I know there is something you're not telling me,' Jennifer insisted. 'I mean, you've been awfully distracted the past few days.'

'Look, Jennifer,' Marty said, sighing. 'I just have a lot of stuff on my mind, okay? I just have some things that I need to work out?'

'Yeah, like what?' prodded Jennifer. 'Why don't you tell me?'

'Like, uh, do I have to tell you everything?' Marty asked, rather defensively. 'Do I have to tell you ever little thought that's on my mind? Can't I have a little bit of privacy?'

'Fine, Marty!' huffed Jennifer. 'If you're going to be that way, then we don't need to keep seeing each other.'

'Wait a minute, Jennifer!' Marty exclaimed, blinking back tears. 'Do you mean to say you're breaking up with me?'

'Are you dense, Martin McFly?' Jennifer snapped. 'What did I just say to you?'

'You just said, uh, I dunno,' Marty mumbled, staring at the ground.

'Do I need to spell it out to you, Martin McFly!' snapped Jennifer. 'I just told you I was breaking up with you! You must be awfully dense, if you couldn't catch that.'

'Look, Jennifer,' Marty insisted, pleadingly, 'I'm not dense! I guess I just didn't want to believe that you really were breaking up with me. Look, I'm sorry, okay? I didn't mean what I said. We can work things out.'

'Save it, Marty!' seethed Jennifer. 'It's over! We're done! We're finished! I never ever want to speak to you ever again!'

Then Jennifer angrily stormed into the house, slamming the door behind her. Marty just stood on Jennifer porch, stunned. He couldn't believe what had just happened. Jennifer had just broken up with him. Blinking back tears, Marty slowly headed over to Doc's garage. He couldn't understand why Marty was so angry with him.

oooooooooo

'Hey, Marty, what happened?' asked Calvin, with concern, as Marty stepped into the garage. 'I thought you were going to spend the whole evening with Jennifer.'

'She broke up with me,' Marty said, sadly. 'I couldn't tell her about my time travel trip, so I had no idea how to tell her why I was a bit distracted. She even accused me of seeing another girl - which is definitely not true. Now she doesn't ever want to see me again.'

Marty then sat on the couch and began to cry. Calvin sat down next to Marty, and put his arms around Marty, while Marty sobbed brokenly.

'Oh, Marty, what wrong?' gasped Doc, as he stepped into the room. 'What happened?'

'Oh, Doc, Jennifer just broke up with him,' explained Calvin, as he rocked a sobbing Marty back and forth. 'I imagine he's been really wrestling with keeping two sets of memories straight. Please, Doc, can't we let Jennifer know about the time machine? I mean, she's your friend, too. It really upsets me to see Marty so broken-hearted. Surely Jennifer cannot stay mad at him for long, can she?'

'Well,' pondered Doc, 'I suppose I don't really see any harm in letting Jennifer know. I would hate to think that I'm responsible for the two of them breaking up. Besides, come to think of it, Marty and Jennifer are destined to marry in the future - and have two kids named Marlene and Marty Jr. Great Scott! This could result in a paradox, if we don't get them back together.'

'Good grief, Doc!' breathed Calvin. 'I didn't even think of that! By the way, who do I end up marrying, in the future? I know I had a son named Calvin Jr. I'm just a little curious.'

'I really shouldn't tell you, Calvin,' Doc explained, gently. 'Remember, we cannot live our lives by what might happen in the future. We have to live for today. You know what I mean?'

'So then, why is it so crucial that we get Marty and Jennifer back together?' asked Calvin, confused. 'Not that I don't think they should be together, of course - but why would their not being together create a paradox? I thought you said the future wasn't written, yet. So which is it, Doc?'

'Well, I just don't want to take any chances,' Doc explained, gently. 'At the very least, it is only fair that we let Jennifer in on the time machine. I mean, this whole trip to 1955 had majorly impacted Marty's life - to the extent where he now has to contend with two sets of memories. Anywa, even if we don't do this for the space-time continuum - we should at least do it for Marty's emotional well-being. It's all my fault that Jennifer broke up with Marty, and I must do my part to fix this up.'

Then Marty lifted up his tear-stained face, and softly said, 'Please don't blame yourself, Doc. I should have been upfront with her two days ago. I should have insisted that we show Jennifer the time machine. After all, if we are destined to marry, someday, she deserves to know about that aspect of my life.'

Doc then embraced Marty, while Marty wept a little. 'Well, Marty,' Doc said, gently, 'I certainly don't want you to get in the habit of letting everyone know about the time machine. We can, however, let you tell Jennifer. If Calvin ever gets a girlfriend, he can tell her, too.'

'I'm not too broken up over not having a girlfriend,' Calvin said, softly. 'Since I know I have children in the future, I guess that means I am destined to find my girl, someday. Anyway, Marty, I'll try talking to Jennifer, if you want me to.'

'That might not work,' Marty said, quietly. 'She might think I'm pretending to be you. Maybe she'll listen to Doc.'

'Well, Marty, I will try my best,' Doc said, giving Marty's shoulder a gentle squeeze.

'Thanks, Doc,' Marty said, with a small smile.

Author's Note: I would like to thank SeleneTheVampireDeathDealer for helping me come up with ideas for this chapter.

4:30 PM PST

Doc had decided to call up the McFly's home, to see if Marty had managed to reconcile with Jennifer. He had been worried about his young friend all day. After about two rings, someone had finally answered.

'Hello! This is the McFly residence!' replied a familiar voice.

'Marty, is that you?' Doc asked, gently.

'Uh, no, this is Calvin,' Calvin said, softly. 'Unfortunately, Jennifer is still mad at Marty. He's in his bedroom right now, feeling very depressed. He hasn't wanted to talk to anyone, since coming home.'

'Yeah, well,' replied Doc, 'I guess I can't say that I really blame him. I'll try calling up Jennifer, and see if she'll listen to me. Have you tried talking to Jennifer, yet?'

'No, I haven't,' said Calvin, sighing. 'I'll try coming to her house later tonight, and try talking to her. I mean, it's not like Jennifer to get so mad.'

'Yeah, Jennifer seems like such a sweet gal,' agreed Doc, 'and, I mean, she does like me. I'm just not as close to her, and I am to you and Marty.'

'Well, dinner is just about ready,' explained Calvin, 'so I'd better hang up, now.'

'Okay, Calvin, it was nice talking to you. Good bye!'

Doc then hung up the phone, with a heavy sigh. Doc then tried to ring up Jennifer's phone number.

'Hello, this is Jennifer,' said Jennifer, as she answered the phone.

'Hi, Jennifer,' replied Doc. 'It's me, Dr. Brown. I would like to explain to you about...'

'If it's about Marty, I don't want to hear it,' Jennifer said, flatly. 'I am never speaking to him ever again.'

'Whoa, Jennifer, isn't that a little harsh?' Doc asked, gently. When there was no answer, Doc continued, 'Look, can you at least come over to my lab. There is something I would like to show you?'

'Why can't you just tell me about it over the phone?' demanded Jennifer.

'Because you wouldn't believe me, unless you saw it,' insisted Doc.

'Oh, sure, Dr. Brown,' spat out Jennifer, 'you're acting just like Marty. You can't even trust me to believe you!'

'No, it's not that, Jennifer,' insisted Doc, rather pleadingly. 'What's wrong with showing you some proof? Please, Jennifer, this is really important.'

'You just want me to get back with Marty, don't you?' seethed Jennifer. 'Well, forget it! It ain't going to happen.' Jennifer then hung up on Doc.

'Well, Marty, I tried,' Doc said, sighing defeatedly.

oooooooooo

Calvin was nerviously walking over to Jennifer's house. What if Jennifer wouldn't listen to him, either? After all, Calvin looked just like Marty, the boy who Jennifer was mad at. Somewhat trembling, Calvin had rang Jennifer's doorbell.

'What are you doing here, Calvin?' Jennifer asked, coldly. 'If you want me to get back with Marty, then forget! It ain't going to happen.'

'Aren't you being a little too hard on Marty?' asked Calvin, as tears were burning his eyes. 'Has Doc called you, yet?'

'Yes, Dr. Brown did call me,' Jennifer said, crisply, 'and I told him the same thing I'm going to tell you! Marty and I are finished! I am not getting back together with him - and not you, nor anybody else on this planet is gonna make me change my mind!'

'But, Jennifer, please...' protested Calvin, with desperation.

'Oh, wait a minute!' Jennifer said, as a funny expression crept across her face. 'You're not Calvin at all, are you? You are none other than Martin Seamus McFly, pretending to be your twin just to try to convince me to get back with you!' Jennifer chuckled coldly, and continued, 'Nice try, Martin! Too bad that didn't work! Now you get off my property before I call the police and have you arrested for trespassing.'

Without saying another word, Calvin hurriedly scrambled off the Parkers' property. He had never seen that side of Jennifer before. He wondered if Jennifer had other problems, that were completely unrelated to Marty. With a heavy heart, Calvin trudged on home. He supposed he shouldn't be too surprised that he couldn't get Jennifer to listen to him. Still, he felt Jennifer was being awfully unreasonable.

oooooooooo

Marty was sitting on his bed feeling dejected. For the first time since returning from 1955, he had refused to join his family for dinner - as he really didn't feel like eating. He couldn't believe that Jennifer wouldn't let Doc explain to her about the time machine. Of course, Marty and Calvin had been friends with Doc for much longer than Jennifer had - so he supposed it shouldn't have come too much as a surprise that Jennifer would rebuff Doc's attempts to patch things up between them. Still, Jennifer and Doc had grown rather fond of each other.

Marty was sifting through his cassette collection, trying to find some music that might soothe him. Too much of the music had reminded him of Jennifer. He then found a cassette of psychedelic rock tunes he had recorded off the radio. Maybe that tape would soothe him a bit. Just then, there was a knock on the door.

'Who is it?' called out Marty.

'It's Calvin,' replied his twin. 'Can I come in for a little bit.'

'Sure, I guess,' muttered Marty. 'Did you try talking to Jennifer, yet?'

'Yeah, I did,' Calvin said, with a heavy sigh. 'You were right, Marty. She did accuse me of being you, pretending to be me. I guess it was because I sounded so desperate, but it's only because I care a lot about you. It bothers me to see you so depressed. You really do mean the world to me, Marty.'

'Thank you, Calvin,' Marty said, softly, blinking back tears. 'I understand that both you and Doc had tried your hardest to get through to Jennifer - and I really do appreciate your effort. I just don't get why Jennifer is being so stubborn, though. I honestly didn't mean to hurt her. I wonder if she has other problems.'

'Yeah, Marty, I thought the same thing,' Calvin said, softly. 'Say, didn't you tell me that Jennifer's grandma was in the hospital?'

'Oh, yes, I did,' Marty said, with realization. 'Yeah, Calvin, that could be it. I know how close Jennifer is to her grandma. Maybe she's worried that her grandma may die, or something.'

'Well, Marty, I'd better get to doing my homework, now,' said Calvin. 'Will you be okay?'

'Yeah, I guess,' mumbled Marty. After Calvin had left the room, though - Marty had flopped down on his bed, buried his face into his pillow, and began to cry. It seemed like Marty's life was starting to fall apart.

oooooooooo

Jennifer was on her bed, playing really loud heavy metal music. Jennifer did feel a pang of guilt for having coldly broken up with Marty - but then her anger had taken over. It's his own damn fault, Jennifer fumed. He couldn't even trust me enough to tell me what's on his mind. He treated me like dirt.

'Hey, Jennifer!' called out her dad. 'Let's go to the hospital, now - and check up on your grandma, okay?'

'Sure, Dad!' called out Jennifer. 'I'll be right down. I just have to comb my hair first.'

Jennifer anger towards Marty then turned towards grief and desperation about her grandma. Her grandma was only 65 years old, and she was too young to die. She hoped desperately that her grandma would be okay. She and her grandma had always been very close. She thought of the many times she would bake cookies with her grandma - and of all the stories that her grandma told her, of when she had been a little girl. Please, God, prayed Jennifer. Let Grandma be okay! I really need her.

'Hey, Marty,' asked Calvin, 'should we play Nintendo for awhile?'

'Sure, I guess,' replied Marty, as he sat up from his bed. 'Let's play Super Mario Brothers, shall we? That's a great game.'

'Okay, I'll go set the Nintendo up, then,' said Calvin, as he was reaching for the game cartridges.

Marty sighed, as he stood up from his bed. He still felt extremely depressed over losing Jennifer, but he hoped that playing Super Mario Brothers would help take his mind off of Jennifer. He couldn't help but cling onto the hope that Jennifer will eventually get over her anger with him.

'Do you want to go first, Marty?' Calvin asked, gently.

'Sure, thanks,' replied Marty, as he managed a small smile. Marty then grabbed one of the game controls, and began to play. By the time Marty had reached the first level dungeon, he had lost his guy. Marty was a little bummed, as he usually played better. He sighed a bit, in frustration.

'Oh, chin up, Marty,' said Calvin, as he tickled Marty under the chin a little. 'Try to think of what makes you happy.'

'Yeah, Calvin, I guess you're right,' sighed Marty. 'It's just that I can't get Jennifer off my mind. It really upsets me to know that he's mad at me.'

Marty then had a craving for ice cream. He went over to a refridgerator, and scooped himself a heaping bowl of chip and mind ice cream. He had scooped up a bowl for Calvin, too. Then Marty carried the bowls back to his room.

'Whew, ice cream!' gushed Calvin. 'Thank you, Marty! I could certainly go for something cold and creamy.'

'Yeah, that's just what I was thinking,' replied Marty. 'Chip and mint ice cream is my absolute favourite. It's so delicious and creamy.'

oooooooooo

Doc was lying on his bed, concerned about Marty, when the phone suddenly rang. Doc picked up the phone and answered.

'Hello,' replied Doc, 'this is Dr. Brown.'

'Oh, Emmett, I'm so glad you're home,' replied Karen Lewis-Hopkins, one of Doc's best friends from childhood. 'How are you doing?'

'I guess I'm doing okay,' Doc said, with a little sigh. 'I'm a little concerned about Marty, though.'

'Now, Marty,' asked Karen, 'he's one of the McFly twins that you're friends with, right? What happened?'

'Yeah, he's one of the McFly twins,' replied Doc. 'He had a little falling out with his girlfriend, Jennifer. The two of them have been dating for nearly two years, now - and Jennifer got really mad at Marty. Marty just happens to have a lot on his mind, and Jennifer got angry with Marty for not confiding in her.'

'That sounds awful,' Karen said, sympathetically. 'So Marty is all broken up over it?'

'Yeah, you could certainly say that,' Doc said, sighing. 'Marty is such a dear friend of mine, as is Calvin - and it bothers me to see either of them being depressed.'

'Well, you certainly are a very caring friend, Emmett,' said Karen. 'You have to realize, though, that you cannot force Jennifer to make up with Marty. The more you try to push for Jennifer to make up with him, the more resentful she will become. It's best for you and Marty to just give Jennifer her space. Also, you cannot count on them making up. Maybe Jennifer might never make up with Marty - and then Marty would have to move on with his life. I still remember the first time I had my heart broken. It is, without a doubt, very painful - but it is also a part of life.'

'Yeah, Karen,' sighed Doc, 'you're right. You're absolutely right. I guess I shouldn't push it too much.' Then, in an attempt to change the subject, Doc asked. 'So how's your hubby and the kids doing?'

'Oh, Brad and I are doing great,' explained Karen. 'Suzy just won an award for singing Stairway to Heaven in a talent show. Just think, she's only five years old, and she's a huge Led Zeppelin fan. I'm so proud of our youngest daughter. Billy just came home from college for a few weeks, and he...'

Doc had listened intentively, as Karen continued to explain to him about the goings-on about her family. He couldn't stop thinking about Marty and Jennifer, though.

ooooooooooo

'How's my little pumpkin doing?' asked Grandma Parker, as Jennifer walked into the room.

'I'm doing alright, I guess,' said Jennifer, as she hugged Grandma Parker. 'Are you feeling better?'

'Oh, yes, sweetheart,' gushed Grandma Parker, as she returned Jennifer's hug. 'I should be released from the hospital in about two days. So how are things between you and Marty?'

'I broke up with Marty,' Jennifer said, flatly. 'Things are over between us. I am never talking to him ever again.'

'Oh, sweetheart,' gasped Grandma Parker. ''Don't you think that's a little harsh? What did Marty do to you, that got you go mad at him.

'It's not what did,' fumed Jennifer. 'It's what he didn't do. He refused to tell me what was on his mind. That fact that he doesn't trust me enough to even confide in me shows how little he really thinks of me. Grandma, we have been dating for almost two years - and I am insulted that he could treat me this way.'

'Oh, honey,' pleaded Grandma Parker, as she gently placed her hand on Jennifer's shoulder. 'Just because two people really love each other, it doesn't mean that they need to know each other's thoughts. A person is entitled to some privacy, isn't he?'

'Yeah, I guess,' said Jennifer, blushing a bit. 'So you really think I'm being too hard on Marty?'

'Yes, very much so,' replied Grandma Parker. 'Just think about I've said, okay? Holding a grudge is not healthy for anyone. It only creates bitterness in your heart, and makes you feel bad.'

Tears then filled Jennifer's eyes, as the wisdom of her grandmother started to think in.

oooooooooo

Marty was lying on his bed, trying to get some sleep, when the phone suddenly rang.

'Hello?' Marty said, slowly, as he answered the phone.

'Hey, Marty, it's me, Jennifer,' explained a familiar voice.

'Oh, Jennifer,' gasped Marty, as his heart nearly skipped with joy.

'Look, Marty, I'm sorry about everything I said to you, okay?' said Jennifer, sounding a little tearful. 'I was talking to Grandma this evening, and she made me realize how wrong I was to lash out at you. So, will you take me back?'

'Of course, Jennifer,' said Marty, smiling. 'Can I come over for a little while. I was trying to fall asleep, but I'm not tired anymore.'

'Sure, I'd be happy to see you, again,' Jennifer replied. 'I know there's really no excuse for me to lash out at you like that, but I've been real worried about Grandma. I guess it made me feel more snappish than usual.'

'I understand, Jennifer,' Marty said, softly. 'Just give me a few minutes, and I'll be right over.'

'Okay, I love you, Marty,' said Jennifer, softly.

'I love you, too, Jennifer,' replied Marty, as he hung up the phone. Then Marty grabbed his skateboard to head over to Jennifer's home.

October 31, 1985
3:10 PM PST

After school, Calvin and Marty had met up with Jennifer.

'Hey, Jennifer,' said Marty, putting his arm around Jennifer, 'how about coming over to Doc's garage with us?'

'Sure, I'd love to,' replied Jennifer, smiling. 'Oh, yeah, Doc had called me yesterday, telling me that he wanted to show me something. I was still so mad at you, though, that I had refused. Marty, will you ever forgive me for lashing out at you like that? I feel so horrible about it, now.'

'Of course I forgive you, Jennifer,' Marty said, softly. 'I forgave you last night, when you called. Try not to sweat it, Jennifer. Nobody's perfect.'

'Oh, thank you, Marty,' Jennifer breathed. 'You really are the best, Marty, and tomorrow is our anniversary.'

'Oh, yeah, just think,' Marty said, smiling, 'Tomorrow, we will have been dating for two years. Well, except for that little fight we just had.'

'My God, has it been that long?' asked Jennifer, smiling.

'Okay, Jennifer,' Marty teased, 'now you are sounding just like the Doc.'

'No kidding?' Jennifer asked, laughing. 'Sometimes I can't even grasp half of what he says.'

'Hey, don't worry, Jennifer,' Marty said, gently. 'You're certainly not alone. Sometimes, I can't understand half of what he's saying - and I've known him since I was six. I've known him for over ten years.'

Then Calvin loudly cleared his throat, causing Marty and Jennifer to glance over at him.

'Oh, Calvin, I'm sorry,' Marty said, blushing. 'I guess I just got caught up in the moment.'

'Yeap,' Calvin said, smirking, 'you two lovebirds are definitely made for each other. It's hard to believe you two were fighting just yesterday.'

'It's normally not like me to hold a grudge,' Jennifer said, her face turning red. 'I guess I was just worried sick about my grandma. I was worried that she might die.'

'So, how is your grandma doing?' Marty asked, softly.

'She's doing much better, now,' Jennifer said, smiling. 'She said that she should be released from the hospital very soon. I was so relieved when she told me that.'

'That's good to hear,' Marty said, softly, as he put his arm around Jennifer.

'Yeah, we're really close to our grandma, too,' Calvin added. 'Grandma Sylvia died when we were only two, but we're really close to Grandma Stella. Grandpa Sam can be a bit gruff at times - but he has a soft heart, too.'

'Yeah, we really enjoy baking with Grandma Stella,' explained Marty. 'That maybe explains why I like baking so much, even though it's generally considered a female's activity. I remember when Calvin and I would visit Grandma after school, and she always had cookies for us. She's a very fun person to be around.'

'Sounds like your grandma is a lot like mine,' Jennifer said, smiling.

Then the trio had reached Doc's garage. Marty knocked on the door.

'Is that you, Marty and Calvin?' asked Doc.

'Yeah, it's us,' replied Marty. 'Jennifer is with us, too.'

'Oh, I am so happy to hear that you two made up,' Doc exclaimed, excitedly.

'Yeah, I really couldn't stay mad at Marty for long,' Jennifer said, smiling. 'Also, my grandma had convinced me to make up with Marty - and I have always trusted my grandma to give good advice.'

'Okay, well, Jennifer,' stammered Doc, 'there is something I need to show you. So come with me.'

Marty, Calvin, and Jennifer had silently followed Doc to the DeLorean. Doc then opened up the DeLorean door, and he showed Jennifer the time circuits.

'Whoa, Doc!' exclaimed Jennifer. 'What is that?'

'Well, you see, Jennifer,' explained Doc, 'this is a time machine?'

'A time machine?' Jennifer asked, incredulously. 'Are you serious, Doc?'

'As unbelievable as that might sound,' explained Doc, 'I am serious. You see, I remember it vividly. I was standing on the edge of my toilet hanging a clock - the porcelain was wet. I slipped, hit my head on the edge of the sink. And when I came to, I had a revelation - a picture, a picture in my head, a picture of this.' Doc then showed Jennifer the flux capacitor, and continued, 'This is what makes time travel possible. The flux capacitor.'

'Flux capacitor?' asked Jennifer, stunned.

'It's taken me almost 30 years and my entire family fortune to realize the vision of that day,' Doc explained.

'Okay, Doc,' Jennifer said, sighing a little. 'If this really is a time machine, can we take a little trip through time?'

'Yeah, I suppose we can,' Doc said, somewhat hesitantly. 'Is there any time in particular that you have in mind?'

'Yeah, how about the 1960s?' suggested Jennifer. 'Maybe 1965? I'm kinda fascinated with that decade.'

'All right,' sighed Doc, 'I suppose we can. Let's drive over to Hill Valley Park, and then we can head back to 1965. We can't stay long, though. We don't want to risk disrupting the space-time continuum. Also, let me try to find you some appropriate clothes for that time period.'

'Sounds like a deal,' Jennifer said, smiling.

'Uh, Doc,' called out Calvin, 'how are we all going to fit into the DeLorean?'

'Well, I suppose we'll just have to squeeze in tightly,' said Doc. 'Why don't you three start walking over to the park - and I'll find you some clothes, then I'll drive the DeLorean over and meet you guys there.'

'You're the doc, Doc,' Calvin said, smiling.

Marty, Calvin, and Jennifer then headed over to the park.

oooooooooo

About 15 minutes later, Doc had driven the DeLorean over to the park. He then handed the teens some clothes to put on.

'The pants you guys are wearing should be fine,' said Doc, 'but you guys should change your shoes and shirts. I mean, we must remain inconspicuous, and blend in with the folks of that time period.'

'Got, it, Doc,' said Marty, as he took off his shirt, and changed.

'I really like this top,' gushed Jennifer, as she put on a rather colourful tye-dye shirt.

'We're going to be hippies,' Calvin said, smiling.

Then, after the teens had finished changing, Doc put the clothing into a bag, and then all four of them had piled into the Delorean. Marty and Calvin squeezed next to each other - then Jennifer sat between them, on their laps. Doc then imputed the date on the time display panel to OCT 26, 1965 6:00 PM.

'We should be back here in about five minutes,' Doc told the teens.

'Good,' replied Calvin, 'because we have a Halloween party that we would like to attend tonight.'

'All right, time circuits on,' Doc informed the teens. 'Marty, Calvin, and Jennifer - brace yourselves for temporal displacement.'

Then Doc began to pilot the DeLorean over the trees, until he got up to 88 miles per hour - then the DeLorean broke the time barrier.

Author's Note: I would like to thank SeleneTheVampireDeathDealer for helping me come up with ideas for this chapter.

October 26, 1965
6:00 PM PST

'Well, kids, here we are,' announced Doc, as he landed the DeLorean at Hill Valley Park. 'We have arrived here at precisely 6:00 PM on October 26, 1965.'

'Wow!' breathed Jennifer. 'So this time machine really does work? Where should we go?'

'How about going over to Lou's Cafe,' suggested Marty, 'if it's still there? I know it was a popular hang-out with teens in 1955, so it might be the same in 1965.'

'Why don't I stay here, and guard the DeLorean?' suggested Doc. 'That way, we make sure that nobody can steal it. Besides, an old geezer like me hanging around teenagers would definitely cause me to stick out like a sore thumb. Then, of course, I also cannot risk running into my younger self. So be careful, kids, okay?'

'We will, Doc,' said Marty - as Calvin and Jennifer nodded their heads in agreement.

'By the way,' added Doc, handing Marty some money, 'here's $50 for you guys. That way, you kids have the proper currency for this era.'

'Thank you, Doc,' said Marty, smiling. 'See you later!'

'Be back in three hours!' Doc called out, after the teens.

oooooooooo

As the teens had left the park, Marty looked around and took in the sights around him. Marty noticed that the town looked a bit more modernistic than it did in 1955 - but it still looked a little ancient, compared to 1985.

'I guess Doc wasn't kidding,' breathed Jennifer, as she looked around. 'I guess he really did build a time machine.'

'Shhhhh,' warned Marty, 'let's not talk about it right now. There are other people around, and we cannot let them hear us talking about time travel.'

'Oh, yeah, right,' stammered Jennifer. Then, noticing something, Jennifer said, 'Oh, there it is! That's Lou's Cafe! That's where Lou's Aerobics is in 1985.'

'Lou's Cafe was there in 1955, too,' Marty whispered to Jennifer. 'Let's go in and order something, shall we?'

'Make sure you don't eat too much,' Calvin reminded Marty and Jennifer. 'Remember that we have the Halloween party to attend tonight.'

'Oh, yeah, right, Calvin,' stammered Marty. 'I must also remember that they don't have Pepsi Free - and they probably don't have Tab yet, either.'

'Do they have any diet pop in this era?' asked Jennifer.

'I'm guessing they didn't,' replied Marty. 'They only have regular sugared pop.'

'I can't stand diet pop,' remarked Calvin. 'I don't understand how you guys can stand to drink the stuff.'

'Well, I don't care for sugared pop,' argued Jennifer. 'That stuff tastes too sweet. I guess I'll just order a coffee or something.'

Then the trio stepped into the cafe, and they heard Twist and Shout by The Beatles blaring from the jukebox. Most of the teens there, male and female alike, had long hair. Marty suddenly began to wonder if he and Calvin might be considered 'square', because their hair was relatively short. The three of them grabbed a booth right next to the jukebox.

Lou then walked up to the trio, and asked, 'What would you kids like to order.'

'I'll have a Pepsi,' ordered Marty, 'and a large order of mozzarella sticks with marinara sauce.'

'Make that two large orders of mozzarella sticks,' added Jennifer, 'and I'll have a coffee.'

'Just give me a Pepsi,' said Calvin.

'So,' Lou said, as he jotted down the order, 'two large orders of mozzarella sticks with marinara sauce, two Pepsis, and a coffee. Will that be all?'

'Yes, sir,' replied Marty. 'Thank you.'

'Are you guys really going to eat all that?' Calvin asked, looking at Marty and Jennifer. 'That's not going to give you much room for the Halloween party.'

'Well, they're serving bratwurst and baked beans,' Marty said, making a face, 'neither of which I can stomach. The only thing that sounds good are the chips and the cake.'

Just then, two hippy girls walked over to the table.

'Are you guys new in town?' asked the blonde. 'My name is Victoria, and I can almost swear I've never seen you guys around. I'm sure I would remember seeing a pair of twin boys as cute as you.'

'Uh, Marty is already taken,' Jennifer said flatly, as she protectively put her arm around Marty.

'How about you?' Victoria asked Calvin, coyly. 'Are you taken? What is your name?'

'Uh, no, actually I'm available,' Calvin said, smiling at Victoria. 'My name is, uh, Artie. I'm Artie Jones.'

Good thing he thought to use a different name, Marty thought, breathing a sigh of relief. After all, if word got around that there were a pair of twins named Martin and Calvin in 1965 - that could create a huge paradox, especially if people realized that the twins looked exactly like 'Calvin Klein' from 1955. Granted, 'Calvin Klein' had only been in 1955 for a week - and nobody had ever photographed him. So, he didn't want to take such a big risk.

'Marty and Artie, eh?' asked Victoria, smiling. 'Those are such nice names.'

'So what about you?' the brunette asked Jennifer. 'What is your name? My name is Yvonne.'

'My name is, uh, Jessica,' replied Jennifer. 'My name is Jessica Hoffman.'

'So, Jessica,' asked Victoria, 'how long have you and Marty been dating?'

'We've been dating for two years, now,' Jennifer said, beaming with pride. 'In fact, our anniversary is tomorrow.'

'Oh, you lucky girl,' gasped Victoria. 'You are so lucky to be dating a guy as cute as Marty. How long are you guys staying in town?'

'We are, uh, just here visiting some relatives,' explained Marty. 'We, in fact, have to leave town tonight.'

Victoria then looked bummed, and sighed, 'Aw, I was hoping to get to know Artie more. You guys are the cutest pair of twins that I've ever laid eyes on.'

Marty and Calvin were both blushing at the compliment. Then The Sound of Silence by Simon and Garfunkel started playing from the jukebox.

'Oh, isn't that such a beautiful song?' gushed Yvonne. 'I totally adore Simon and Garfunkel! Their music is so beautiful.'

'I agree,' Marty said, smiling. 'They have very lovely harmonies.'

'I prefer Bridge Over Troubled Water,' said Calvin.

'Pardon?' asked Yvonne, confused.

'Oh, sorry,' Calvin said, blushing, 'I guess I was thinking of a different duo.'

'It sounds to me like a hymn we sing in church,' said Yvonne.

oooooooooo

'So, kids, how was it?' asked Doc, as the teens returned to the park.

'Oh, it was great,' gushed Jennifer. 'Some hippy girls were hitting on Marty and Calvin, though. Other than that, though, they were nice.'

'I thought for sure they would think me a square,' Marty said, blushing, 'as my hair isn't exactly long. I'm flattered they still thought I was cute.'

'I made a mistake of referring to Marty by his name,' Jennifer said, quietly. 'Luckily, Calvin had thought to use a different name.'

'Oh, thank goodness!' breathed Doc, with relief. 'I forgot to warn you about that. I'm sorry.'

'Well, Doc,' Jennifer said, smiling, 'I guess you really do have a time machine.'

'Well, I'm ready to head back to good old 1985,' Calvin said, smiling. 'Let's get our asses back to the future.'

'Sounds like a deal to me,' Doc said, as he stepped into the DeLorean.

The teens then all squeezed into the DeLorean, as Doc prepared to head back to 1985.

October 31, 1985
4:15 PM PST

As soon as Doc had landed the DeLorean back in 1985, and parked it into Hill Valley Park, Doc and the teens stepped out and sat at a picnic table. Nobody else was around, so Doc figured it was okay for them to discuss time travel.

'Okay, Jennifer,' Doc said, sighing, 'Now I suppose I should explain to you why Marty has been distracted. This would definitely help you to understand Marty better.'

'All right, Doc, what is it?' Jennifer asked, perking up.

'Okay, I must warn you,' Doc informed Jennifer, 'it is kind of a long story - and you also have to be thinking fourth-dimensionally?'

'What does that mean?' asked Jennifer, confused. 'Fourth-dimensionally?'

'Okay, Jennifer,' Doc asked, sighing, 'how good of an imagination do you have?'

'I'm pretty imaginative,' Jennifer said, smiling.

'Okay,' said Doc, taking a deep breath, 'in order to understand the concept of a fourth spacial dimension, imagine yourself as a two-dimensional creature - living on the surface of a piece of paper. Are you still with me?'

'Yeah, Doc,' replied Jennifer, smiling, 'I think I've got it.'

'Okay, then,' continued Doc, 'now, there are sheets of paper above and below you. However, as a two dimensional creature living on the surface of a piece of paper, you would not be aware of the fact that the paper you are living on exists in a three-dimensional universe, because your field of vision would be limited to the surface - or the length and width of the paper.'

'Okay, Doc, I'm imagining,' said Jennifer. 'Continue on.'

'Therefore,' continued Doc, 'you would not be aware of the existence of the dimension of height - or the third spatial dimension - because you would not have the ability to look in the direction of a third spatial dimension.'

'Okay, I think I understand what your getting at,' said Jennifer, thoughtfully.

'So, by that analogy,' explained Doc, 'just like the hypothetical two-dimensional creature I postulated to you, the field of vision of three-dimensional beings - which would include us - would be limited to the 'surface' of a three-dimensional space, manifold with respect to a fourth spatial dimension.'

'Okay, I'm still following you,' Jennifer said, sighing a little.

'This means that we, as three-dimensional beings, would not be aware of the existence of a fourth spatial dimension,' continued Doc, 'because we cannot 'look' in the 'direction' of a fourth spatial dimension.'

'So are you saying that time would be the fourth dimension?' asked Jennifer.

'Precisely,' replied Doc. 'Now that you understand, I can explain to you about Marty.'

'All right, then,' replied Jennifer. 'Go on.'

'Okay, then,' explained Doc, 'in the early morning of October 26, I had revealed the time machine to Marty. However, because I had borrowed plutonium from a Libyan terrorist group to fuel the time machine - and I did not make them the nuclear bomb that I had promised, they came after me to gun me down that night. As Marty was driving away from the terrorists, he had landed back in November 5 of 1955 - which happened to be the same day that I hit my head on the sink, and came up with the idea for the flux capacitor.'

'Whoa! Whoa! Whoa!' protested Jennifer. 'Let's back up here! Why did you make a deal with a group of terrorists, and where was Calvin?'

'I'm getting to that, Jennifer,' Doc said, gently. 'Now here is where you need to think fourth-dimensionally. When Marty went back to 1955, he had no memories of this timeline. He came from a timeline where I was shot dead, Lone Pine Mall was Twin Pines Mall, Biff Tannen still bullied Marty's father, and Calvin didn't even exist.'

'Whoa, Doc,' breathed Jennifer, 'this is heavy!'

'Anyway,' continued Doc, 'back in 1955, Marty wrote me a letter, warning me that I would be shot be terrorists. Initially, I tore up the letter, because I figured that I shouldn't know too much about my future. Luckily, though, I had thought to tape the letter back together - and now I'm glad I did, as was Marty. Now I had to see to it that I befriended Marty some 20 to 30 years into the future. When I met Marty, I was surprised to find out that he had a twin. That's when I suspected that things were different. In 1955, Marty had shown me a picture of himself with his older brother and sister - but no twin. Then I also remembered what Marty told me about his father, and how he never stood up to Biff. I was somewhat good friends with George, who I knew was an aspiring science fiction writer - and also that he routinely hired Biff to wax the family car.'

'Whoa!' breathed Jennifer. 'That is a little too much to take in.'

'Anyway, to cut to the chase,' said Doc, 'I had to see to it that Marty would arrive back in 1955 on the same day, in order to prevent a paradox from happening. That's also why I didn't invite Calvin. That's why I put on a bullet-proof vest, and went ahead with doing the test at the mall. The gunshot did knock me out a bit, but I came to about half an hour later. Then I heard Marty crying next to me. I felt so bad about the hell I had put him through.'

'Okay, so what happened next?' asked Jennifer.

'Well, when Marty woke up the next day,' explained Doc, 'he initially had no memory of this timeline. He didn't even remember who Calvin was. However, as we were in 2015, saving the children of Marty and Calvin from going to jail, Marty's memories had returned to him. So Marty now has two sets of memories.'

'Whoa!' gasped Jennifer. 'That must be very confusing for him.'

'Right,' replied Doc, 'that is why Marty had been so distracted.'

'Oh, okay,' said Jennifer, as a look of understanding crept across her face. 'Now I understand why he was distracted, and why he couldn't tell me. I feel so sorry now for breaking up with him. I'm glad that my grandma convinced me to make up with him.'

'Right, now you get it,' Doc said, smiling. 'Well, I think you guys better head home, and get ready for the party tonight. You guys should change back into your own clothes first.'

'We will, Doc,' said Jennifer, smiling.

Doc then embraced all three teens.

October 31, 1985
6:30 PM PST

Marty, Calvin, and Jennifer were all at the Halloween party that was being held in the gymnasium of the high school. The dance was just about to start, and Marty and Jennifer were out on the dance floor. Marty felt so happy to have Jennifer back.

"Oh, Jennifer," gushed Marty, "you make such a beautiful fairy princess! I also really love that glitter in your hair. I see that your friend, Zoe, is also a fairy princess."

"Thank you, Marty," cooed Jennifer. "I really like your Superman costume a lot. I also really like Calvin's Batman costume. It was so nice to see the two of you show up in superhero costumes. So you said you Uncle Toby bought them for you guys?"

"That's right," Marty replied, warmly. "Uncle Toby found a set of superhero costumes - with one Superman and one Batman - so he really thought to give them to us, on our birthday. Since then, we've been planning to wear them for Halloween."

"Your uncle seems like such an amazing person," Jennifer gushed. "Zoe and I have actually been planning our costumes for over a month, now. Just think, I'm a fairy princess, dressing with Superman! What an odd combination, eh?"

Maty paused for a minute, before finally saying, "Naa! I don't think so! I think a fairy princess and Superman might really work together as a great team." He then paused to look around, before adding, "Hey, take a good look at Zoe and Zach out there!"

"It's awesome," Jennifer agreed. "I mean, we have your best friend dancing with my best friend. It's such a shame that Calvin doesn't have anyone to dance with. I think he will find his match, one of these days. At any rate, he still seems to be happy!"

"So, Jennifer, shall we go get some more brownies?" asked Marty, as he smiled at his girlfriend. "Those are so delicious. I can hardly get enough of them."

"Oh, yeah," agreed Jennifer, "they are very chocolately and gooey! I guess shouldn't eat too much, though. Oh, well, this is a special occasion - and diets are overrated."

Calvin then walked up to the couple, as he said, "Oh, you two make such an adorable couple. It's quite nice to see you two together again. You two definitely are made for each other. There is certainly no question about it. I'm sorry I ever envied you two."

"Thank you, Calvin," replied Jennifer. "Say, can I take a picture of you two together? The two of you look so adorable in your superhero costumes! You guys look great!"

"Sure," Marty replied, as he hugged Jennifer, "and thank you so much! Yeah, I've always preferred Superman, while Calvin was always big on Batman. It really was wonderful for Uncle Toby to think of us, when he saw that set. He's awesome!"

"Marty and Calvin," Jennifer told the twins, "why don't the two of you stand over by the skeleton over there? Put your arms around each other, and then I'll take several snapshots of you. The two of you just look so adorable together!"

"Okay, we'll do that," Marty told Jennifer. To Calvin, he added, "This will be great!"

Marty and Calvin then stood next to the skeleton, and they put their arms around each other. Marty smiled very fondly, Jennifer snapped three photos of them.

The Power of Love by Huey Lewis and The News then started playing, as Marty reached out for Jennifer, and the two of them headed over for the dance floor.

"Oh, Jennifer," gushed Marty. "This song always reminds me of you! Even after all we've been through, that song still holds quite a special place in my heart. I do still wish I could be performing at the dance tonight, it's so nice to dance with you."

"Yeah, Marty," Jennifer replied, warmly, "this song always reminds me of you, too. I guess the audition judge didn't like any of the bands that performed, and that's why we have a jock jockey tonight. He is playing such wonderful music, though."

"It's almost like this song was written just for us," Marty agreed, laughing a little. "I still remember just how bad I felt last Friday. That week in 1955 did help to give me plenty of confidence. I'm glad I decided to send that tape to the record company."

"What do you think of Back In Time?" Jennifer asked Marty. "I still have a hard time getting used to the fact that Doc really does have a time machine. One day, I would like to go back in time, and see my parents back when they were in high school."

"Actually, Jennifer," Marty said, gently, "that has got to be one of the most stressful weeks of my life. It wasn't exactly a week of fun and games for me. I had to make sure that my parents fell in love with each other, so that I wouldn't become erased from existence. Hell, I even started to fade away on the night of the dance - but, luckily, my parents had kissed just in time. Believe me, Jennifer, I don't think you would want to live through that."

"Oh, goodness, Marty!" gasped Jennifer. "I didn't even realize you had to go through all that. Now I understand why you've been a bit distracted. I mean, you certainly could have used a break from that trip. I think time travel would be more fun, if you didn't have to worry about all those time paradoxes, and such."

"Oh, yes, I hear ya, Jennifer," Marty said, softly. "Anyway, yeah, whenever I hear Back In Time, I think about my trip back to 1955. I guess I just ended up becoming lucky that we knew when the lightning would strike the clock tower. Otherwise, there's no telling how I would have returned to 1985. I would hate to have been stuck in 1955. Of course, I was worried that Doc would be shot dead by terrorists, as soon as I returned to 1985 - but I really would have missed you, my friends, and my family. Besides, I didn't even quite have the same relationship with Doc back in 1955, as I did in the present."

"In what ways was Doc different, back in 1955?" asked Jennifer. "I suppose, in a way, it would quite be like me meeting you at seven - or at 37, for that matter. It would just not be the same thing. I do wonder who you dressed up as for Halloween at seven."

"I think Calvin and I went as a two-headed ghost that year," Marty replied. "In the original timeline, I also went as a ghost - but I just had nobody to be a two-headed ghost with. I sure would like to think I'd still be dressing up for Halloween at 37."

"I'm not sure what rather amazes me more," Jennifer commented, stunned, "just how much things must've changed, or just how much things must've stayed the same. So, getting back to the question, how was Doc different, back in the yea 1955?"

"Well, for starters," replied Marty, "the Doc of 1955 did tend to see me as a kid - as I guess we haven't really had ten years to become good friends. He also wasn't as used to affection. I guess he seemed a bit more conservative back then, if you know what I mean. Anyway, we did still come to enjoy each other's company."

"So your life has changed a lot," asked Jennifer, "since you returned to 1985? I guess that might also explain why you've been rather distracted. Now I sure am sorry that I lost m cool with you. I wish I had been more understanding the last couple of days."

"Yeah, quite a bit," replied Marty. "My parents are a lot happier and more confident, and Biff is no longer bullying my dad around. Also, I was initially shocked, when I found out that I had a twin. I did briefly wonder if I might end up being re-named Calvin, as soon as I returned to 1985. Of course, I guess it turned out being that my name would still be Marty, but I would have a twin named Calvin."

"I'm sure Calvin was rather shocked," Jennifer mused, "when he found out that you were the Calvin Klein of 1955, eh? After all, your parents did actually name him after that Calvin Klein, right? It's is a very ironic twist of irony, in my opinion."

"I'm pretty certain that that is correct," replied Marty. "I can imagine that that would be even more of a shocker for Calvin, than it is for me. I mean, I can imagine what it would seem like, from his perspective. It'd probably feel a little creepy."

"Well, I'm quite glad that Doc told me about the time machine," Jennifer said, rather softly."Now I understand you a bit better. Maybe Doc will let us take more trips into the past. It was actually rather nice getting to visit 1965 a little earlier today."

"Well, actually," said Marty, sighing, "I think I would like to take a little break from time travelling. At least, our trip to 1965 hasn't really affected this timeline. Granted, we were only there for about three hours, though. Still, the thought is real frighening."

"Such a fitting topic fo Halloween," Jennifer replied, laughing. Then, after a pause, she asked, "You know where I would like to go, Marty? I would very much love to go to Woodstock. Now there is a very memorable event to live through."

"Actually, Jennifer," Marty said, gently, "it's my understand that it was pouring rain throughout most of the event. So Woodstock really is not all that it was cracked up to be. I do agree with the hippies that we need more peace and harmony in this world - but, sadly, it really seems like a lot of the former hippies have now become yuppies."

"Yeah, I suppose you're right," Jennifer said, sighing. "I suppose the hippie movement is a bit overrated. I really do enjoy the psychedelic music of that era, though."

"Oh, yeah," agreed Marty, "psychedelic rock is nice music. Even though, I could do certainly without Janis Joplin and Joe Cocker. Well, how about a kiss?"

"That sounds fine with me," Jennifer said, quietly. "It's great that we were able to make up, just in time for Halloween. They're playing such good music tonight."

Marty then leaned over to kiss Jennifer. It was so hard to believe that they have had a fight not long ago. Marty had a feeling that his future with Jennifer was looking up.

Author's Note: BTT is short for Before Time Travel, as I said at the beginning of the story. I don't think Marty would differentiate between the two timelines by the mall's name. So that's why I'm referring to the two timelines as BTT and ATT.

November 1, 1985
3:10 PM PST

After school, Jennifer was walking home with Marty and Calvin. The part of Marty that grew up in the BTT timeline thought of how nice it was that his mother now approved of his relationship with Jennifer. Oh, there were a few things he missed about the BTT timeline - but, overall, Marty was much happier in the ATT timeline.

'Well, Jennifer,' Marty asked, as he turned to Jennifer, smiling, 'do you know what day it is today?'

'It's the day of our anniversary, of course,' Jennifer replied, smiling. 'We have been dating for two years, now. We haven't even fought that much, come to think of it. Even the last fight we had didn't last very long.'

'Yeah, Happy Anniversary to the two of you,' said Calvin, smiling. 'I remember being real jealous, when the two of you first started dating. Of course, I feel ashamed of my actions, now. I think it's great that the two of you made up - and that you are together, again. I really think the two of you are destined to marry, someday.'

'Thank you, Calvin,' Jennifer replied, smiling. 'I still remember when my best friend first started dating. I was also a bit jealous, because I was so concerned that my best friend might not have any time for me, anymore.'

'Yeah, that's pretty much how I felt about Marty,' Calvin said, nodding. 'Of course, I now realize the foolishness of my actions. Of course, Marty and I will always remain best friends. We are identical twins, after all.'

'I sometimes wish I had a twin,' Jennifer said, sighing. 'Then, again, it is pretty nice being an only child. I used to wish I had brothers and sisters, when I was younger - but, now, I'm pretty glad that I don't. Having a twin would still be nice, though.'

'Well, we don't always get along with Dave and Linda,' said Calvin. 'Marty and I almost always do get along, though. We may have some differences of interests, but it certainly doesn't keep us from being best friends.

'Well, if we all had the same interests,' said Jennifer, 'life would be pretty boring. Besides, opposites do sometimes attract. Marty and I don't have all of the same interests, either. It's nice that we share a lot of the same taste in music, though.'

'Do you like any non-rock genres?' asked Calvin. 'I mean, I enjoy rock and roll as the next person - but I something think that Marty is a little too obsessed with rock and roll. He says he cannot imagine life without rock and roll.'

'Hey, now, Calvin,' protested Marty, 'we all have our passions, don't we? Rock and roll music just happens to be a big passion of mine. It does not mean that I'm obsessed. I mean, I do have other interests, you know.'

'Marty is right, Calvin,' Jennifer said, gently. 'I cannot imagine life without indoor plumbing for instance - but it doesn't mean that I'm obsessed with indoor plumbing.'

'I guess I see what you're saying, Jennifer,' Calvin said, sighing. 'I guess what I'm just saying is that, I enjoy rock and roll music, but it's just not my life.'

'Look, Calvin,' Marty said, somewhat defensively, 'I may play the guitar, and I may have a band, but it doesn't mean that I think of nothing but music all the time. It's the same way as the Doc is passionate about science. Would you say that he's obsessed with science? I wouldn't say so, even though I don't have the same passion for science like he does.'

'All right, you boys,' Jennifer chided, laughing a bit, 'can we stop arguing, now? We're almost at your place, now. Say, do you guys have any popsicles? I could certainly go for a popsicle right now.'

'I think we do have a few popsicles,' Marty said, smiling. 'You like cherry, right?'

'That is correct,' replied Jennifer, smiling. 'You like orange - and Calvin likes grape, right?'

'That is correct,' replied Marty, smiling. 'This certainly works out great for us, as we don't have to fight over popsicle flavours.'

'That is certainly one good way of looking at it,' Calvin said, laughing a little.

'Well, here we are,' announced Marty. 'We're home now.'

As the trio stepped into the house, Lorraine went to great them right away.

'Hello, Marty and Calvin!' called out Lorraine. 'Oh, hello, Jennifer!'

'Hello, Mrs. McFly,' called out Jennifer, smiling. 'How has your day been?'

'Well, it's been a little busy,' explained Lorraine, 'but that's okay. I think I'm due for a raise, soon.'

'Oh, good for you, Mom,' gushed Calvin.

'I am so happy to hear that,' agreed Marty.

'So, Marty and Jennifer,' said Lorraine, smiling, 'isn't today the day of your anniversary? You've been dating for two years, now.'

'Oh, yes, Mrs. McFly,' replied Jennifer, putting her arm around Marty, 'we certainly have. We hope to marry, someday.'

'So, do the two of you have any special plans for tonight?' asked Lorraine.

'We certainly do,' Marty said, smiling. 'I've arranged to have a very special dinner by Jennifer's place.'

'Awww, that's so sweet,' gushed Lorraine. 'You two remind me so much of my hubby and me. I mean, I still remember when George first took me out to dinner. It's like George and I were made for each other. I will always remember that Calvin Klein.'

The three teens all smiled at each other, as they knew who 'Calvin Klein' really was.

'What are you guys all smiling at?' Lorraine asked, smiling. 'No, it wasn't Calvin Klein the fashion designer - even though he was wearing underwear that had the name on it. Come to think of it, you boys kind of do resemble him.'

'Oh, really?' Marty asked, feigning surprise.

'I've always wondered who this mysterious Calvin Klein was,' Lorraine continued. 'I mean, I've only known him for a week - then I never heard from him, again.'

'So you named me Calvin after him?' asked Calvin.

'Oh, absolutely,' said Lorraine, smiling. 'We planned to name our third child Martin, after George's great-granduncle - but when it turned out that you two were going to be twins, then I decided that you two should be named Calvin and Martin. After all, the boy's name was Calvin Martin Klein. I still think you boys look a lot like him. Maybe it was just a coincidence, though.'

'Yeah, probably so,' replied Marty, as he gave Lorraine another hug.

'Well, kids,' continued Lorraine, 'I have a meeting to attend right now - but I should be back by nine. You guys take care of yourselves.

'We will, Mom,' Marty and Calvin replied, simultaneously.

Lorraine then hugged Calvin, before she left.

Jennifer then turned to Marty, and said, 'Well, Marty, I should get home for a little while. I guess I'll see you in a few hours, right?'

'Oh, you bet,' replied Marty, as he hugged Jennifer. 'I love you, Jennifer.'

'I love you, too, Marty,' replied Jennifer, as she hugged Marty back.
