I can't help but wonder if Braig/Xigbar had intentions of using Ienzo/Zexion's body when it came time for him to use another.
In the cutscene where they pass each other in the hallway, Ienzo is the first to notice him and Terra-Nort conversing with eachother, possibly hinting that he had suspicions on them for a while. Making Ienzo a potential threat to Braig's agenda (at least until Ansem was banished).
And then there's the other cutscene where Zigbar has a conversation with Zexion about Xemnas and the two chambers. Why would he bother Zexion on the topic unless he believed he knew something, or if he wanted to pass off that information to him for a reason. Was it bait for a trap, or just testing Zexion's curiosity???
I've often wondered whether there was a reason for why Zexion and had a lot of screen time in KH (aside from maybe being a fan favorite) and I figured it's because there had been some plans for Ienzo that haven't been put out there in front of us yet.
Ienzo was the youngest of the Ansem's apprentices and would've likely become Ansem's heir since he was being raised by him as his own child. If Luxu/Braig had any plans for a potential backup after using his current body, then out of the apprentices present, Ienzo would have been the most convenient choice.
A child raised and beloved by royalty with an immense thirst and capacity for knowledge on the heart and other worlds. Sounds like a perfect candidate for Luxu.
