Demetrius is a strange old bird. He heads the theater department and teaches drama to students. He’s also busy each semester putting on a play, generally a classic Greek or Russian piece. Demetrius claims the theater is haunted, and that if Duncan does nothing to silence the “impetuous” ghosts, he’ll leave. It’s not the ghosts that bother him, it’s that they don’t appreciate the artistic process. He’s been making this threat for more than a decade now.
