I know you like Juliet, Folie! I try and be gracious toward Juliet on your behalf!

You make a valid point about her though... she seemed a meek and sweet sort of person pre-island... something has happened to her (willingly or unwillingly) to make her have a very cold exterior - a judo-throwing, gun using, coup instigating, stare-down-Smokey chick. It might have to do with the fact that all the men in her life are ... hmmm. what's the word I'm looking for?... how would you describe the guy hit by the bus, Ethan, Goodwin (Goodwin might have been the exception, but he got killed too) and ...ugh!... Ben Linus. I would hope she would have the courage to really change sides and tell EVERYTHING to Sayid, Jack, Sawyer, and Kate (I think the more who know the better), not out of real fear that Sayid will kill her if she doesn't, but because she wants to help the Losties and get out of Ben's grasp. She's the key to the Losties getting a leg up on what's happening on the island and against Ben Linus.
