Rodolphus gives a snort of laughter. "Maybe," he says, "if you wore arm holsters I wouldn't do that." It doesn't seem very likely though.
"Truly Severus," Rodolphus says solemnly. "You deserve a place of honour for what you did." He gives him a slight bow. "All right, all right. Don't get your knickers in a twist." Rodolphus smiles acknowledgment of the compliment though. "Horace Slughorn was a toady and a fool. He picked his favourites and fawned over them disgustingly. Even mudbloods sometimes! He also," he sets his jaw grimly, "had a fondness for his students. His male students. I don't know if he tried anything with anyone else, but he did with me. That's when I broke his nose. And I told him if he tried anything with Rabastan, they'd never find all the pieces. He knew I meant it too. Naturally, I went to Dumbledore and tried to have him sacked, but obviously he wasn't." He kicks viciously at a cat that's on it's way to dinner at the nearest pile of fish.
