<- Possible Spoilers -> I posted this a long time ago, and I'm wondering if more people have noticed this; When Xemnas disappears after being defeated, the animation is basically the same as when you defeat (Or Sora does in normal KH2 in a cutscene) Roxas. And, as you probably know, after that happened Roxas joined/went in/fused/became one with Sora. If you see where I'm going with this, I think that Xemnas may have became one with his Original Self (Xehanort) which would mean that Xehanort is still alive somehow. If that was Xemnas' only chance to survive, I wouldn't be surprised if he used it/had it, as his last resort. Even if it meant no longer having his own body, since Xehanort could become a Heartless again (probably, and if so, Xemnas could come into the world again). That being said, if he indeed did become one with Xehanort, do we know he couldn't just take over the body? Sora and Roxas are the only other example of that happening (right, or am I forgetting something?) and since Roxas didn't have any reason to take over Sora, how do we know it couldn't happen? This is merely my speculation and reasoning based on what I know and or remember about the series, so only post constructively please, don't bad-mouth me because you feel differently. XD
