Two DADA Teachers-- Neither Belong

It's Harry's fourth year, and there's a new guy at Hogwarts. . . Edward Elric has the eyes of a werewolf, he says he's a wizard, and he has many odd quirks. Who is he really? The Golden Trio are going to find out. And why are there two Defense Against the Dark Arts teachers? This year's going to be a mess. . . Canon pairings for both! FMA:B! Rated T because of Ed.
