"Tsk, I'm certainly not mad at you for hiding behind a suit of armor more than seven years ago. That would be beyond ridiculous. I'm mad at you because you implied that your guilty conscience was the only reason you helped me with Greyback. And because less than two minutes later you accused me of - how did you put it? - letting you fuck me to return a favor. I can assure you that such a thing is beneath me. It wasn't a gratitude fuck, forgiveness fuck, pity fuck or whatever you want to call it."
