So not fair, LB.

lol
I posted this idea somewhere else, but I thought I had it figured out half way through Des's flashback epi, that he was saving Claire (or even Aaron), but then when he told Charlie that HE was going to die, I was satisfied with that as the "twist" ending that we get on Lost occasionally, but now I'm starting to wonder if they're going to pull the old double-switch-a-roo & it really IS Claire after all!
