Not only the Sun and Jin but wasn't that somebody places an ad asking for rape scenario in an episode of The Inside?
Alias: Do you guys think that the reintroduction of of doubling suggests that they're going to bring back a former character with a different actor? Vaughn? Sark? Who knows who?
Also, when Jack is talking to Balthazar (what is the character's name?) in the shooting range and BG says something about his mother saying that if somebody was worth shooting once, they were worth shooting twice, I suddenly had the idea that he was going to be Sydney's long lost brother, cousin, great-nephew by a different father, another lost Direvko sister, or etc., but that maybe just because I've watched the show too long.
