This came to me last night and I am pretty sure it is just my paranoid mind taking over, but here it is. If you read the spoilers, do you remember someone, maybe Kristin, saying that there would be a Sydney-Vaughn kiss in the finale, but Vaughn would not be himself? This made me start thinking...with all of the masks in the season finale with Sydney being Lauren and Lauren being Sydney, was it really Vaughn???? Is that what she meant? We all kind of assumed that Sark was in jail because the last time we saw him, he was. But was he by the end of the show? How did Vaughn know where to go to find Sydney? He didn't unless he talked to Jack. Sark would have known where Lauren was.
