Well, on the theory, I actually herd something about the BHK's white cloths being white and Sora's black, actually having something to do with the storyline. So it is possible that the BHK is Sora's light. Then again, I'm poor, and can't afford a gameboy advance, so I can't say anything that might be hinted in CoM.
