Let's review the death poll shall we?
A spoiler source said 8 of the following characters would die before the end of 6x16:
A second spoiler said 4 characters would die during The Candidate.
A third spoiler said there were only 5 original Losties surviving the sub.
Now so far we have seen 5 deaths:
Ilana in Everybody Loves Hugo.
Sayid, Sun, Jin, Frank in The Candidate.
None of the spoilers are proved wrong yet.
Thus three more characters will die.
There are three groups, imo:
The "Dead Meat": Zoe and Widmore. Both are doomed.
The "Saved For A Reason": Sawyer, Desmond, Claire, Hurley. Along with Jack and Kate, these characters have looked Death in the face in the past few episodes. I don't think they were saved just to kill them off in 6x16. I think they go on to the Finale.
With Claire especially, Flocke had her right there and he didn't try to kill her. And he previously had a talk with her about her not being a candidate. I just don't see Claire dying anytime soon.
The Doomed Trio: Ben, Miles, Richard. If we take Zoe and Widmore as two deaths, then one of this group will die. I think Richard is the likeliest, followed by Miles. Possibly the spoiler is wrong and BOTH will die. Or possibly the spoiler is RIGHT, and both die, and ZOE LIVES to the Finale?
