Xavier is your enemy but he also picks on you whoever he sees you or whenever he's bored.

One school day you were being picked on by some other students and Xavier saw that then he quickly pushed the other students "Hey, fuck off that's my nerd, not yours only I pick on them, so go find someone else!" He said sternly to the students with his British and American accent then he turns to you and takes your glasses "Ha, loser come get your glasses now"
