"Oh, for fuck's sake, Malfoy. Just Levicorpus me!" Potter yelled and the word had barely left his lips before Draco trained his wand on him and shouted the spell to then watch Potter get strung up in the air by some invisible hand around his ankles. In the process, he flailed around so much that he knocked over a stack of books and a suit of armour - why the fuck did his aunt have a suit of armour? - and everything started duplicating around the floor knocking over more items that started duplicating itself. Somehow, Potter managed to swing the right way and when he then yelled "Liberacorpus!" the next second, he fell back on the floor with the Cup cradled in his hands.
