In terms of what you can expect to have answered in these 12 minutes:
-- Where's Walt, and what has he been up to since the island?
-- Why do the women have trouble getting pregnant on the island?
-- What's up with the polar bears?
-- Um, and what's up with Room 23?
-- The full dealio behind the Hydra station and why Chang has so many aliases.
There's probably some more stuff in there that I missed, but feel free to pick it apart below. Don't know how long this will stay online, so catch it while it's hot after the jump ...
