Wow.  That was a goodie.  Not only did tonight's episode officially mark the show's crossover from vaguely sci-fi-ish supernatural drama to full-on science fiction awesomeness, it was also gripping, thought-provoking and emotionally intense!  Yay Desmond!  Yay Penelope!  Yay Sayid! 

I've said it before and I'll say it again: if I was on that island, I would never leave Sayid's side -- not for two seconds.  I'd be with him so much, people would start to talk, but I wouldn't care.  He's the only one on that island that is A: sane, B: smart, and C: a badass.  I'm just sayin'.
