The scene is pretty ambiguous, already I've seen a multitude of theories stating Xehanort may not be who we think he is, but that's not for here right now. An interesting thing to note is that Braig is awake, but Isa isn't, but in the cutscene that chronologically follows this one, both Isa and Braig are missing. At this point it's pretty fair to assume Isa isn't really all clued up on what's going on with the Xehanorts. But who can blame him right? I mean Young Master Xehanort knows just as little, and it's pretty apparent Braig doesn't have a clue anymore either. There's even a slight hint that Master Xehanort may be betrayed by one of his own when watching this scene, at this point we now know that both Braig and Young Xehanort are still clamming on a keyblade.
Something I've taken from this above all things is how strange it is that two of MX's closest organisation members don't actually know what's going on, when in Dream Drop Distance everyone seemed so sure of themselves. Does no-one else find that incredibly odd? I think Braig and Young Xehanort are going to play much larger roles in 3, potentially taking on the roles of second and third antagonists, they have hidden agenda's just like Master Xehanort himself, interestingly enough (at this point it's worth noting that they both hold parts of Master Xehanort's heart, even if Young Xehanort's is just his own really).
Another thing that really comes to light with this new cutscene is despite actually being Xehanort, Young Xehanort is not like his other incarnations, he's a separate entity with his own goals and they don't necessarily match his older self's. It adds an interesting new layer to his character in my opinion, he really could go anywhere from here.
