I'm about a season and a half behind on Lost.  Ever since I canceled pay TV I've lost my DVR....so i only get around to it online when I think about it.  So I'm still about 6 episodes from the end of LAST season.  But I'm pretty sure I know what's going on anyways.  I've had it figured out since day 1.  This is all a dream Bob Newhart is having.  Mark my words.
