Theory on how the story ends

[Witch_Doctor]

I think the story ends exactly where it bagan. We're alive is a re-telling of events of the last 4 years by Michael, taken from him and various sources. It starts in his present time, which is four years ahead, to which he does not sound like a zombie and it is him telling the story, not anyone else.

I don't understand a word you said but I agree 100%!
