I think the flashforwards take place a good few months after we saw Jack visiting Hurley at the mental hospital, in the basketball court. Hurley now seems crazier than ever and his imagining of Charlie, amongst other things, affects Jack after he visits him again. We see Jack starting to lose control, having visions of his dead father and being extremely paranoid over Kate and who she spends time with when she goes out. It is revealed, after Jack questions Kate about where she's been (after a suspicious phone call), that she was out doing something for "him". This "him" turns out to be Sawyer, whose fate is finally revealed as still being on the Island, voluntarily it seems. Which again raises more questions; Why did Sawyer choose to stay on the Island letting Kate leave? Who was Kate with? What "thing" was Kate doing for Sawyer, especially if he's still on the Island?

It also seems that Jack knows that Aaron is his nephew, evidenced by him telling Kate that she's not even related to him, which in turn implies that he knows that he's related to him. So is it because he didn't want to bring up a child as his own who he knows is actually his nephew? Or is it because Claire has died and he doesn't want to be reminded of her death every day? I think it's more than likely the former, as he would most likely be able to get used to the latter after some time to think it over.

Jin started show some of his past and true colours by threatening Charlotte and demanding that when the rescue helicopter comes to pick up her and Daniel that Sun be on it too when it leaves again. Jin clearly knows how to intimidate and threaten people, knowing exactly which buttons to push. Instead of threatening Charlotte personally he threatens to break Daniel's fingers (and of course implying a lot worse afterwards) and this then makes Charlotte pay attention. This little incident also showed that Charlotte has a lot more to her than one would think; she knows how to speak Korean, for one thing. Perhaps I, and I'm sure a lot of other people, have been underestimating her.

It seems a little strange to me that Sawyer has all of a sudden become really protective of Claire and her baby. Ever since the incident with the explosion last week Sawyer has done everything he can to guard Claire and Aaron and keep them both safe. Even after Miles has somewhat proved his "loyalty" to the survivors, even coming out and saying that Keamy and his men are not his buddies, Sawyer is reluctant to even let Miles go near Claire. We saw Frank running out of the jungle and warning Sawyer, Claire, and Miles of the fact that if Keamy finds them he will kill them. This shows that these men are also not Frank's buddies, and that both him and Miles (and presumably Daniel and Charlotte) did not sign up for what has happened. I love the fact that we have got some new allies and also some new enemies. We were then left with a cliffhanger ending when we see Aaron in the jungle next to a tree, with no sign of Claire. Has she been kidnapped? And if so, by whom?
