So, yes, it's true, some of us who haven't watched it yet also don't care enough to really care about spoilers, but if I'm getting spoiled I want to be properly spoiled, not set up for disappointment. Was there actually an alt universe created, or is it just purgatory and you made the other stuff up?

Because I can't tell from your phrasing if your version starts with "The whole last episode could have been..." or if it starts several paragraphs earlier.

I was into it when I thought the first few paragraphs were actually part of the show. Kind of Evangelion-meets-Back To the Future, but in a cool way.

I think now I'm just confused, which I guess isn't a new thing WRT Lost...
