I always like the back stories, but I particularly liked Hurley's tonight. I did have Dave pegged as an imaginary friend as soon as the one guy threw the basketball over his head to Hurley. I also figured Libby must be associated with the mental hospital in some way, but I had figured that since Hurley said he recognized her. I liked hearing about why Hurley had been committed. It will be interesting to learn more about Libby.
"Henry"....who is the guy that will kill him? And the bearded Zeke is nothing? He sure knows a lot about the Others, but I wonder if he really is one still. Just my conspiratorial mind expecting another big twist, I suppose. I wonder if he made up the story about not pushing the button or if he really did not push it.
