I'm totally convinced that Xem just sits on his butt all day in the castle (or goes up to drool over Kingdom Hearts some more) while the rest of the Org is out working. Seriously, there's a scene where Roxas wants to talk to Xemnas, so he corridors to the Round Room, and Xemnas is already sitting there. Alone. Not really doing anything. DOES HE SERIOUSLY SIT THERE ALL DAY DOING NOTHING???? XD Worst boss ever.
i noticed that too! haha he just waits around until someone needs him in there... but he IS obsessed with the power of NOTHING, so i suppose he thought by doing nothing he would...be uh more powerful....by nothing...yea no logic in that
