I don't think it will be Charlotte, I think she's there for the whole polar bear back in time thing, so she probably won't get killed (if she gets killed) until after they find the Orchid station. Could be Claire, though. Which wouldn't be much of a mind bender, since the psychic that said she HAD TO raise Aaron later said that he was a fake. And why else would Kate claim the baby as her own? Yep, Claire is toast.....but will it be tonight? The real question is who just got a DUI in Hawaii? I think thats killed more Losties than anything!
