Other than being defeated by the lights which is obvious,I have a feeling there is gonna be a betrayal again. This time revolves around xehanort heartless. I bet that he would want kh all by himself and have conflicts with the 13 darkness ( mostly xehanort and xemnas).It could be a twist but hey that's just speculation.

That'll be weird to me. Arguing with yourself.

Yeah, Ansem could probably pull that of. Or maybe he will betray them to get closer to Riku and possess him. So far it has seemed to me that he doesn't really care about Xehanort's plans that much. But he HAS been running after Riku a lot. Maybe he will even save Riku's life?

 Xehanort himself will somehow firetruck up like he always does and be his own downfall. It's like what Xigbar/Braig said : It's like Kingdom Hearts itself rejects Xehanort.

No,i don't think so.

Ansem is gay for Riku.

But, why would he want to go against his own plans?

Villians always betray each other no matter how much they think alike because they always want more power and don't want to be restricted by their "comrades".
