if master xehenort, the old man from the final mix secret ending, is able to weild the keyblade, then why can't xehenort or xemnas or xehenorts heartless? they are teh same person, masters of the keyblades, and yet the, uh, future xehenort's do not know how to weild it. why is that? memory loss? then how was roxas able to weild it, its not like he remembered who he was or why he could or anything, he had no memory of sora, well little memory of sora, and the keyblade.
