The unfortunate victim began to jerk about like a puppet on a string, unable to control the movement of his legs. There was no grace to the dance, pure awkward motion. The student's eyes bulged in fear, and he was too frightened to even cry out. The other students stepped around him, fearful of being caught up in his predicament.
Roddy applauded Bella's actions; she always had his approval. He was glad that he was able to make her laugh, he loved the sound of her laughter - it answered a need within himself, something dark and coldhearted.
"Isn't it a shame he doesn't have a partner?" Rodolphus declared, and before those around the victim had the sense to scatter, he had chosen one at random and aimed his own wand at him,echoing Bella's spell, which set the second victim to begin to dance uncontrollably as well.
They were drawing a crowd now. Only the Slytherins were laughing, though.
