Thanks Everyone.
@Xion - Alright. Care to elaborate...?
Sure buddy. Not to be mean, but it has been confirmed (correct me if I am wrong) that the Unversed don't exists past BBS. Also, for Braig to be a main enemy, and for Lea to come back, we need to know if their true being did come back to life. The only thing in your theory I can see coming true is a new Keyblade Master coming to be.. Also, like others have said, the whole Princess, Frog thing, (not sure how to explain it lol), would not really fit in to The Princesses of Heart mold. Hope that is good.
