just watched the "Destiny" scene a couple times and I have an idea. Alright so with this Braig vs Xigbar bullshit, for the sake of this thought I'm gonna say he's Xigbar. Not in the sense that he is still a Nobody, but for another reason. Near the end of the scene when he asks "which poor soul shall it be?" YX starts to say S, obviously as in Saix. Now they should obviously be Braig and Isa, and they honestly are BUT aside from Xemnas, they were the only 2 in the Organization that were norted. So what if because they were the only ones norted, they kept their nobody names because of the X in it that relates to Xehanort and the whole thing with the New Organization?
I think this sounds extremely reasonable, likely, and makes a lot of sense when you think about it. So realistically they are Braig and Isa, but because they are a part of the new Org, they will continue to go by their nobody names.
Thoughts? Have you seen this brought up anywhere? If so, I have not
