First the spoilers:

One major character is killed off in the finale (this was mentioned in TvGuide Before)

Another major character gets stuck in another dimension


Now the rumors:

Miguel ends up lost in Hell with no way out risking his life to save Endora

Viki murders Fox in cold blood right after planning his future.

I have a bad feeling Fox will be murdered. I still think Fox is an imposter and the real Fox is alive somewhere being held captive.
