Darian is that teacher the students love to hate. Arrogant and filled with righteous self-importance, Darian teaches calculus with effortless disdain and makes going to class utter hell. He won’t just ask questions. He’ll ask the questions you can’t answer. Some students think he’s jealous of their powers, but Skyler sees it as his job to teach them never to underestimate the human mind; a weaker opponent can always beat a stronger opponent by outwitting him.
