This thought crossed my mind while I was watching a friend beat Xemnas when he's on the dragon for the first time. Xemnas looks like a knight. And in final mix he's talking to Aqua (thats what i've seen people call the woman knight) or her armor and calls her friend then in the E.S battle the knight talks about Xehanort. maybe i'm way off but if you think about it, it could make some sence.
