Hogwarts: the Omnipotent Professor Is Also Troubled

In 1991, three years after graduating from Ravenclaw, Franky Jess resigned from his job as an Auror and returned to Hogwarts as Professor of Defense Against the Dark Arts. So far—— Professor Flitwick was sitting in an empty classroom, frowning and muttering to himself: "Isn't he teaching Defense Against the Dark Arts? What does it have to do with the Charms class!" Professor Quirrell walked into Dumbledore's office and stammered: "Headmaster, I... I want to go back and continue teaching M... Studies." "Oh, you're here too, Professor Bu... Baji." "Hello, Professor Quirrell, I've come to resign—" he said. ... On the other side, Frankie fell into silence as he watched more and more students in the class.
