LAST EDITED ON 03-31-10 AT 09:15 AM (EST)Yeh I don't think Ji Yeon is coming to the island. Though I do think she will "survive" the shooting in the flash sideways. Jack's tomato was a not so subtle clue to that.
One thing is really different though(among other obvious things), this flash sideways baby is concieved before the flight! In the original Jin is sterile off island and they did not concieve until post crash.
Jack and Sun's relationship has changed again since coming back to the island. She appears to no longer have anger towards him!
DH says the best Lost episodes are "when the pieces are moving across the board". He's another gamer!
Edited to add one more thing: Notice the hotel room? All black and white with lots of red accent colors thrown in. Don't know what it means but there are those colors again!
