"Rodolphus found out what about us?" Percy asked, annoyed, because this couldn't possibly mean what Cass was implying. This had to be some sort of Slytherin trick to gain his sympathy, although how they went from Cass kissing a woman to Rodolphus was beyond him. "May I remind you that no one knows about us? No one, so I have no idea what you're trying to say."
He tapped his fingers over his own leg, clearly impatient. "What about your mother? You know if you want to explain, you should try doing just that, because this is ridiculous. How can he find out something no one knows unless you think Bones or I had a very interesting discussion with him, and I greatly dislike Bones, but I doubt she's have tea with the man."
