OK this should be spoiler free - Mib's got these guys, and at least some of them are officially "claimed" if not all, he's trying to get off the island--
What if the "good guys" stop him? What happens to the claimed? Do they go back to normal? Are they screwed? Do they die? "Go to hell?"
Sayid has had such a crappy break, in every timeline, that i hope he gets some redemption.
