Bellatrix had briefly wondered if Lavender would turn up. Though, right on time the pretty, blonde Gryffindor appeared. "Here you are," Bellatrix parroted in a slightly mocking, babyish tone. "I hope you don't have plans for this evening. I have already spoken to Professor McGonagall about your insubordination and she has made it clear that she does not approve and I can punish you further if need be."
"Go get a bucket and brush and you can start with the floor. On your hands and knees," she instructed. Sitting up on the desk, Bellatrix kicked her feet lightly with a smug smile on her face. "And you can close the door if you don't want anyone to see you."
