What if BHK is not only half of Sora, What if he is also part of Riku...Ya I mean Light and Dark equals Twilight, so Sora equals the light side and Riku equals the dark side...Plus he uses the Oathkeeper, the keyblade of light which was given to Sora, and uses the Oblivion which you get after you beat Riku. So he could be half of Sora and half of Riku. There are a couple of problems with this theory. First BHK doesn't look like Riku, but looks like Sora, and he doesn't have any of Riku's looks or details, but he could have his voice and abilities or something. People who think the BFU is Riku's shell he isn't, Replica Riku could have been the shell because he had no heart so basically he is a "nobody" right
