i think a lot about how xehanort has actually met and spoken with the master of masters multiple times and may be one of the very few people who have post age of fairy tales - maybe the only one at all. and like...
does xigbar...know? is he aware? and if he is, i wonder how he feels about it. in my head i get the impression luxu has never been entirely comfortable around MoM but follows him bc what's he gonna do? defy him? hell no. (and i hc MoM as luxu's dad but that's neither here nor there.) and like, the whole point of luxu's character is being shoved off into the great beyond with no guidance, no contact, no nothing except a box and a keyblade.
so when MoM pops up again, starts hanging around xehanort, gives him the /same goddamned coat/, and xehanort eventually gets the /same goddamned keyblade/, and starts being manipulated in the same exact way - like a luxu 2.0....how does that feel?
is he scared? jealous? protective? relieved that at least someone who's still alive knows even a sliver of what he went through? all of the above? who know.
