Okay I seriously havn't been checking in on KHinider latley so I don't know if somebody said this. If you look at the new KH2 poster doesn't BHK look like Riku? I mean seriously what if we've been looking at riku the whole time? Think about it, Riku's body was taken over by ansem, sora kicked ansem's ass but techniacally it was riku's body. What if riku's heart(or soul) inhabattied or created another body just like when sora did after he lost his heart. I ahven't given this serious thought but it makes sense.
