For me the main relevance of this episode is in setting up the emotion chip storyline :ermm:
The sub plot with the boy was a bit odd - if he is that contagious that he has to be put in his own personal greenhouse why wasn't anyone who attended the scene affected etc. Plus of course it was boring crap as well :lol:
I liked Data taking over the Enterprise and countering the crews efforts to regain control but you do have to wonder why anyone with a good voice synthesizer (sp?) can take over the ship :ponder:
It's an alright ep but a bit weak imo :)
I remember one of the infamous errors in this episode - when Data dictates the security code to lock out the Enterprise computers, the code which appears onscreen manages to skip words, add new ones and change other words! :)
