Wow. Awesome episode. I'm not going to try to review the whole two hours, but I want to focus on one main thing - a line that Richard Alpert said to Locke that I think is critical to the main mystery of Lost. Richard told Locke what he had to do if he wanted to save the Island. I have said time and time again that the Island is somehow - sentient - or alive like an animal or some such - but it is definitely aware. The Hostile, or natives, who were there before Dharma, and who precipitated the purge, may simply be aspects of the Island, like ghosts or spirits (which would help explain Richard's never-changing face).

So I'm convinced I'm right. What I'm confused about though is why the Island would throw a hissy fit over a few people living. It just strikes me as juvenile. Like a petty god who demands people to worship itself.

Oh - and that scene at the end. WTF?!? Who was the old lady? Why was she using a computer from the 1980s?
