Exodus (2) - S1-E24
Revealing mistake: When Shannon carries and drags the luggage (some of Boone's) she breaks down and Sayid speaks to her. When he says, "It won't be too much if I carry it for you," he strokes her cheek with his left hand - note the watch. After he says, "I have a hike to lead," in the next wideshot he's still holding her face with his "left" hand. But, note the lack of watch, and her large suitcase is now backwards. They flipped the shot so his right hand would appear to be his left, to keep hand continuity, but it doesn't work. (00:17:10)
