Rodolphus grins. His own nose has been broken so many times it's a wonder it still works. "It makes you look more dangerous," he offers. "And that time I broke your arm," he shrugs. "You zigged when you should have zagged Severus."
He listens, eyes narrowed, to the professorial exchange. He follows Severus to the door. "Don't block the way Severus," he says, giving him a gentle (for Rodolphus) poke in the kidney region. "I'm perishing of hunger right before your eyes you know."
