The things that still sort of does bother me is that all the characters in the flash-sideways are in LA, even the ones who were never on the Oceanic flight to LA or were connected to LA at the time of the bombing. I have nothing against LA (except for the Lakers), but Dogen was from Osaka, Rousseau was French, I believe Bejamin Linus was from Oregon, etc. It wouldn't be impossible for them to all end up there--it is a megalopolis, after all--but I hope something in the main storyline explains it.
This week's episode was a good one. I especially liked Jack laughing after the fuse blew out. It took it to mean he was laughing because it was a sign, but it could also still be nothing, since it's not like the dynamite blew up but they survived.
I like the redemption of Ben, especially since it's not the full redemption it appears to be: it just reveals his complexity. He will remain being shrewd, calculating, and insecure. It's the question of Dogen's "test": how "evil" is he?
I also love the fact that Miles has the diamonds, if only because it ties Nikki and Paulo back in. That episode was such a one-off: it would be interesting for it to play a part, however passively.
