I am wondering what happens to Jack once he gets back to civilization. Apparently at first is quite perky and normal, although he is having a screwdriver for breakfast. But then he ends up addicted to painkillers and about to jump off a bridge. I wonder how much time has passed between these two FF's. I think that people start contacting him like we see happening with Hurley. Creepy people asking about the island, ghosts visiting him giving him a guilt trip.
