The stick stays floating in the air right as the troll tries to swing it back down at Harry again. They all watch as the troll looks up at the stick confused before it drops on to his head, knocking him out and causing him to drop Harry and fall to the ground. The two brunettes stand and move to the two boys, Harry pulls his wand out the troll’s nose earning disgusted exclamations from all of them. He had just finished wiping his wand off and putting it away when a few professors came storming in; Professors McGonagall, Quirrell, and Snape.
