I've been watching the video a lot. I think there are a lot of cuts.
- I think there's a cut on Aqua to see what happens to her
- I think there's a cut right after Ven starts fading away
- I think the next scene with Xehanort juggle Xemnas's piece is out of order. The juggling probably happens after we see the Destiny Trio split up.
- I think the scene with Xehanort smiling and then for like, 2 frames you see Sora? I bet the scene refocuses on Sora there and follows him falling. He might fall into some CoM scenes
- The cut where Roxas drops his icecream is kinda weird. I doubt it happens so quickly like that?
- There's a confusing ending part where we see Xemnas with his fancy light sabers and then Riku and Mickey's blades come flying out of nowhere to interrupt him? I've watched that part a few times and it makes no sense to me. 100% bet that scene is either out of place or happens somewhere else or something.
Also, I've seen people speculate about it already, but it'd be pretty cool if Xehanort wasn't alone at the chest board and Eraqus was on the other side seemingly losing a lot (or losing completely?) I feel like this game between them is very significant. I remember when it was first hinted at, it was just two sketched people talking to each other and we didn't know who they were yet. I should look that up, to see what they were talking about...
Anyway, I so want to know more about this chess game.
