It still bugs the crap out of me on why Vanitas looks like Sora. It's sort of role reversal, I mean Vanitas is the darkside of Ven while Roxas is the darkside of Sora. Well some what dark. But it makes you wonder if Vanitas is truely gone. I mean he's the darkness from Ven, and after Ven joined with Sora's heart you have to wonder if when Sora became a Heartless and let loose Ven as his Nobody, Roxas. You wonder if there was another piece to Sora's heart that fled from him. Like someone who appears like Sora but who's dark and similar to Vanitas. I mean there's something to think over in the following KH games.
