Oo-kay, that was one helluva ending. But I don't get something.
Jack dies, and ended up in the church. But Hurley is alive, and would go on to protect the Island for who knows how many years. So if Hurley dies later, he will end up in the same church with Jack? Soo...no matter when they die, they all "move on" at the same time? Of course, I know, there is no when or where in the post-death timeline, but I think you know what I mean. Is that the case?
