The girls took a break as Theo and Malfoy duelled. Watching them was like seeing magic for the first time, Hermione felt like she couldn't blink for fear of missing something. They both excelled at non-verbal spells by then and didn't bother to utter a word. The movements from their wrists flicked and twisted in different directions as spells hit the stone walls behind them. Occasionally, a large chunk would fall from the wall as a particularly powerful spell hit it with force. Hermione used "repairo" liberally, casting it before the stone could even hit the floor.
