Of all the flashbacks we saw in this episode, the only 1977 lostie who didn't get a visit and didn't get touched by Jacob is Juliet.1- she wasn't really a lostie. 2- They were likely hinting at her death for the end of the episode. She is the only one who will be dead at the beginning of season 6. Hurley, Jin, Sayid, Jack, Kate, Sawyer will all survive. Likely the result of being touched.
Locke, and Sun were also touched, but they're in 2007. Could it be that Locke's body is actually alive? Or that perhaps he is dead but Jacob used his body to take on the form of....Jacob..Which means an impostor Jacob may have been stabbed and thrown into the fire.
