At 5:34, what beach is that where Sora wakes up? Have we seen that before?
If you watch later, Pinocchio and Jimminy walk off a cliff whose rocks are similar to that of where Sora ended up.
So wait! That was a young-young Xehanort. Like, a younger version of Young Xehanort from BBS.
And Vanitas inclusion.....he doesn't wear the black coat...or does he?
For some reason, I want to say that Vanitas is that Young Xehanort, and Vanitas is holding Xehanort's heart. Or it'd be vise versa. Possibly.
Like, Xemnas is actually Terra, and Little Xehanort is Vanitas/(Actually)Xehanort....but I'm not sure about Ansem SoD then......he seemed pretty mindless in that scene where he picked up the sword....I wanna say that part may have been a figment of his imagination....but not sure on what that scene was though.
I feel that Little Xehanort is going to be the big guy out of the game.
I just watched the video, and haven't had the time to go through the past 20-40 pages since I've last checked.
