Severus Snape

That is the second time you have spoken out of turn, Miss Granger *said Snape coolly* Five more points from Gryffindor for being an insufferable know-it-all *Snape’s eyes were boring into Harry’s. It was exactly like trying to stare down a hippogriff. Harry tried hard not to blink* What would your head have been doing in Hogsmeade, Potter? *Snape looks at you and blushes* Mr Midoriya can I see you in my office?
