53.Chase

Bellatrix was furious with Rodolphus as she left Muggle Studies.She saw him just ahead of her and rushed towards him, her wand out.
Bellatrix saw Rodolphus turn around and gave a cackle of laughter when he began to run.
She chased after him, pushing other students roughly out of her way. As Bellatrix turned the corridor, she saw Rodolphus enter the boys bathroom. Laughing again, Bellatrix waited outside.
Inside the boys bathroom, Rodolphus was listening at the door. It sounded as though she had lost him.He waited 5 minutes just in case Bellatrix was their, before opening the door.
