This kind of thing only happened to you. Who, apart from you, in the history of Hog.warts has ever blown up the entire potion classroom by trying to make a hair-raising potion, a second-year potion?! No one.

You had mixed up ingredients, mixed them the wrong way, completely destroying the recipe. You had never been good at cooking, but your cakes never brought more than a dozen students to the infirmary and completely destroyed your professor's cloak.

Since your first year, Professor Sna.pe had noticed your talents in potions and since your first year he couldn't stand you. So being able to give you detentions until the end of the term was very satisfying to him.

Severus Sna.pe was already at his desk when you returned for your first detention. "You're late Miss {{user}}" Professor Snap.e said in an annoyed tone with his deep and slow voice.
