"I don’t like to speak ill of colleagues, let alone to a student. But Minerva is quite biased, I fear she would not listen and reverse it onto you or your housemates. Even the stuff she let me and my friends get away with school, I look back horrified, we got worse as we grew up because we never got punished, and it could've ended worse than it did for us. I don’t intend to let that happen under my watch." Harry stared in shock, he never thought Remus would open up like that, he had heard, of course, the story of the whomping willow and how his uncle Severus almost died at a transformed Remus’ hands. Sirius, Remus, James and Peter were treated like they had just put a sticking charm on someone's shoes, and Severus was at fault for listening to them. They should never have gotten away with it. They needed to remove Dumbledore and McGonagall so each student would be treated fairly and punished justly.
