"Are you saying you don't want to watch, Severus?" Rodolphus smirked, but stopped walking to turn to face him. He looked over the girl, then shrugged. "I'll want to take my time with her, so perhaps you ought to be quick about it and go."
He grabbed the girl's wrist then, to pull her closer to him. He was taken aback when she seemed to snap out of her shock and scream, flailing in terror and managing to get a good handfull of his hair and pull it free and leave a sharp scratch down his cheek before he'd thrown her hard enough into the nearest wall to leave her unconscious again.
