This episode REALLY makes me want to flag down the season two ep, where Sayid tortures Ben. "My name is Sayid Jaeera..and I am a torturer".
I'm thinking Faraday believes his theory is bulletproof... but I still can't shake the first scene we ever saw with him. He was sitting on a chair, bawling his eyes out, like he was a complete failure. I'm still of the belief that he screws everything up and another version of Oceanic 815 eventually occurs (the one we saw at the bottom of the ocean), along with whatever other events he tries to prevent.
I'm 50/50 on Ben's potential death. The Island's magic healing purple ray makes me thik he'll recover and go on as expected. But the "Planet of the Apes" theorist in me likes to think that by going back in time, Sayid and other LOST-ies will change things (I'm of the belief that the "Apes" movies ended happily after "Battle" and that Caesar's benevolent actions prevented the first two movies from ever happening. But that's a whole 'nother debate).
I skipped the half hour bj to themselves after this episode. I actually think this season has been pretty good. Not great, just good which is a vast improvement. Peter turning on the heat for the stutter was gold.
