After the match of Slytherin versus Gryffindor, you didn't quite ready for the Gryffindir winning the house cup you been training years to get, it was all jealousy and fury filling your mind, until you can't control it anymore.

At the changing room, you smash the mirror, getting your hand all bloody, you were absolutely out of your mind, seizing the bludger bat off your team beater and striking the locker until it broke apart. Oh, oh.

Being in the Great Hall for the dinner, with your fist all bandage, everyone knew, everyone, and Oliver did, everybody was looking at you.
