I didn't see anything that happened in the last 3 minutes coming!
I'm certainly not going to miss Ana Lucia, but I hope Libby is okay. I want to know more about her back story.
And what is the deal with Michael? He's been pretty intense and a bit of a loose cannon ever since the Others took Walt, but last night took it to a whole new level. Is he brainwashed by the Others? Is it some sort of deal with the Others to get Walt back?
Also, was fake Henry really coming to get Locke when he got caught in Rousseau's trap? Or is that just part of Henry's mind games?
On a side note, I wish more of the episode (and many of the other episodes this season) had been as exciting as the last few minutes.
