[quote=Doctor Belasco]He's not a secret. Those students relevant to him are supposed to be in the know, and I like to think he has periodic meetings with each of them (which he would take about as seriously as the students) in order to double-check they're not going to go whacko and sabotage another family. He also won't bother to keep his extracurricular activities secret - it's not in his interest for emerging (in more ways than one) members of the magical community to be ignorant of what he does.[/quote]
Which may pose a problem with Paz. He can have the meetings, but he honestly has no idea what's going on (he probably would think it was just a periodic counseling session). Pazel's mother wanted him out of the witch world so kept him oblivious to it all. The Flamels have also kept their promise to leave Pazel out of the circle until he becomes a witch. If he fails to become one, they leave him and his family alone forever.

…But we all know he's going to become a witch sooner or later ;)

@All: Pazel has seen, and maybe been in the same classes with, the other student characters, but that's probably about it. He knows nothing about witches so never treated the non-witches and witches differently. 

As for the other non-college related characters, Paz knows absolutely nothing about. Unless he becomes acquainted with them through some kind of part time job.

Maybe Paz will work at some kind of bar/cafe/restaurant place that a lot of the characters go to. *Shrugs*
