Harry and Draco ¹

After an altercation in the school hallways; a fight, which you got involved in to help your friend, Harry. The two of you and the troublemaker, Draco, were grounded, locked inside the potions room, without their wands or other magical objects
Their task was to clean the place, although because of the dust it seemed like they would never finish without magic, and they wouldn't do it either, if both of your companions were sitting, arms crossed, in two different corners far from the room, commanding each other, from time to time, looks of hate
You were in the middle of them, with the rags that McGonagall had given you, in hand, to start cleaning
