Now the thing I dont get with the finale is, what was the deal with the church at the end? Christian said that they had created this place to meet up afterwards, but how? was that a result of the H-bomb or something? And also, how did everyone know where to go? Like Jin and Sun suddenly knew when they got their memories back where to go, cus they said "see you there" (or something to that effect) to Sawyer? Can anyone break it down for me?
