oh my gosh, lol whats your problem. when i was on here before your thoeries where not any better.
any way, i think bhk could be the other side of soras heart, born from when sora had his heart taken by the heartless in hollow bastion. i think he is the prtector of sora and he is to prtect him at no cost. why is he to protect him? i think that if sora dies or looses his heart then bhk would be gone. so as long as sora is still alive or with us so will bhk i think the geu and dwu is bhk. when the geu walks up to the unknown on the rock, the unknown on the rock says, "he looks just like you". to me this is saying that the unknown on the rock is telling the geu (bhk) that he looks like sora. bhk does look like sora. also i dont think bhk is part of the org.. i think he is dressing as the org. to learn the plans of the org. so he can use what he knows to his advantage and make plans of his own to protect sora. this goes with the king and riku as well.
