I just finished watching the Ana Lucia episode from season 2, "Two for the road", and I noticed something that hadn't occurred to me before. We see Ana Lucia drive Christian to Claire's mothers house at four in the morning in Sydney. This is only a day or two before the departure of 815 and Claire's mother is not in a coma and it would seem that Claire is still living at home. He's demanding to see her and Carole is telling him that he can't. When Christian comes to visit her when she's in a coma in "Par Avion" from season 3, he isn't a disheveled mess. He's visibly in control and presumably hasn't yet been betrayed by Jack. So, how do these flashbacks fit? Any ideas? Just a timeline mistake?
