I dunno, I think the two universes/timelines are real. I think in the end they will merge into one new one. With most of the dead characters getting their life back. Either that or it will be a tough choice between two evils, and they'll pick one that resets everything back to the very beginning of Lost, and they'll end the show with them trying it again to get it right. Ya know, one last FUCK YOU to our sanity from the writers.
