Bens in the coffin, it makes sense. Jack was the only one at the funeral. The guy said nobody else showed up, and Kate's reaction gave it away. I think he killed himself after being taken off the island. Its either him or Lock, since the only person Lock has was his father who was killed. But I dont think Jack and Kate would have reacted that way to Locks death. But who knows. My question is Where is Mike and Walt... They were hinted on at teh end of season 3 when lock was dieing in the ditch and saw Walter. I am stumped.
