I think if we are getting into a "white vs black" good vs evil battle you have to think Christian might be one of the good guys seeing is he was always seen walking around in white tennis shoes. Also if anybody remembers that Jack was asked to retrieve Christians BLACK shoes to put on dead Locke in the coffin before they borded for the island.
I am kinda dissapointed that this show is going away from character driven episodes and now its all just plot driven episodes and the characters are sort of just a backdrop to the whole picture.
For example, Kate, Sawyer, Jack and Juliet were just all over the place last night. Starting with Sawyer, after all of this growth as a person and becoming a different caring character since season one, does a 180 faster than you can blink and dosent care if everybody dies? Kate just changing her mind about the bomb just like that? Juliet basically changing her mind because she got jealous over a look and now wants to blow up the Island? Honestly bad writing last night with character interaction, but plot itself was grade A suspense..
