Okay, so, whew! What a finale!

I have to say that I totally called the fact that the plane was brought down by the electro-magnet that was triggered when time ran out. Good stuff.

Anyone have any theories on the upcoming season?

I think that it isn't Walt in the boat with Michael. That would explain the lady who asked Michael all those questions about Walk that he didn't know the answers to. She said "You don't seem to know him at all." Perhaps a clone? Who knows.

Also, what the heck is the relationship between Pen Whitmore (Desmond's ex-girlfriend) and those two guys monitoring electro magnetic activity? I can't really make sense of that one.
