im going to name the bald guy Master Xehanort for the time being and my theory is that he created a replica of himself when he was younger like Vexen created a replica of Riku....the knights will probably end up killing Master Xehanort and then Replica of Xehanort is going to have no heart so he joins Ansem the Wise to try and gain a heart with the tests that Ansem was doing....but finds that he cant, so he he takes the name ansem to try and make people try to open kingdom hearts and what not.....
on the opposite side another theory i have is that the DS is actually Master Xehanorts nobody, and he can summon him at any time....the only other time that we have seen two people join and split apart is when Roxas comes in and out of Sora...so maybe in KH3 Sora will be able to summon Roxas out of him at will...thus giving Roxas more playing time
btw, wtf ever happened to Replica Riku...he kinda just left castle oblivion without being destroyed didn't he?
