You guys expect answers in a season premiere? Man, you're silly.They only ever give answers to anything in the last few episodes of a season. This is all about the questions.
It did give some answers, though. We now know that Hurley's flashbacks were in fact flashforwards. We also get the new information that, er, he can see dead people. And he is more than likely the one who can do something to get them back to the island, I imagine. And that probably has something to do with seeing Jacob.
Oh, and were there two people inside Jacob's shack, or is it just me?
