still working him out. so far, my thinking is he comes across as a bit arrogant with a dash of charm and good looks to make him not entirely insufferable. rumor has it he hooks up with his students (he doesn't) and has broken hearts among fellow faculty (not intentionally).
i'm aiming to make him a lot nicer with his few friends than he actually appears to strangers and casual acquaintances. he's very loyal and genuine under all that sarcasm, he swears.
