Greyback: “Pleased to see me, Dumbledore?”
Dumbledore: “No, I cannot say that I am… Am I to take it that you are attacking even without the full moon now? This is most unusual… You have developed a taste for human flesh that cannot be satisfied once a month?”
Greyback: “That’s right. Shocks you that, does it, Dumbledore? Frightens you?”
Dumbledore: “Well, I cannot pretend it does not disgust me a little.”
