I don't watch TV, mostly because its an expense I do not need. I do have internet, and thus am able to watch some shows online. Shows like Awake on NBC, which is one of two shows I actually watch. Well the Series Finale happened, the show is cancelled, and the main character is well...... I haven't a freaking clue.
He somehow joins a world where both his wife and son are alive, either he creates it in his own mind, wakes up from a terrible dream, or creates a new reality somehow to live in.
All of these are possible, and frankly the most likely answer is that he is unconscious still from the accident and has dreamed two separate worlds to deal with the potential loss of his son or wife or both. That this new reality is a further coping mechanism, and not the true reality. This would explain the ability of information from one world to play out in another, they both are constructs of his mind. If you notice he doesn't actually remember anything before the accident, no flashbacks to before that night, so somehow I believe his mind is piecing together someway to deal with the accident, and potential tragedy from it.
Further it was hinted that he was drinking before driving, and thus the two worlds and the conspiracy stretching between the two is a way to deflect guilt for possibly killing his family while driving. No ill intent of others, just a stupid choice that may cost him his family, and as such is unbearable for his mind to deal with.
Eh, what do I know, its a tv show, thats been cancelled.
