My guess is the six includes Jack, Hurley and Kate. As to the other 3, I haven’t the foggiest, but I’m going to go with Michael (just because I saw Harold Perrineau’s name in the credits, and if Desmond can’t navigate away from the island, I doubt Mike and Walt will be able to as well), Juliet and Desmond (because they have people to come back to). Mike was in the casket.
Lost dead pool candidates:
- Rose
- Bernard
- Claire (and baby)
- Walt
- Christian Shepherd
- Benjamin Linus
- Sawyer (he put his foot in it with his “I’m always surviving” schtick.
