A few things about Lost

Lost sort of answered some questions yesterday! One being, what happened to Locke, Eko and Desmond after the explosion. And they're all alive - but it seems that Desmond has some kind of psychic power. So then the other thing bugging me was that an other had said to Sawyer who is trapped in a cage the bears figured out how to work the food in two hours. Sawyer asked how many were there, and never got an answer. But now we know there were 2 polar bears on the island and what they were doing there. Sounds weird if you don't watch Lost, but these are the kidn of details fans agonize over. Small steps, but maybe there'll be more answers coming.
