Malfoy: [after Moody humilates him by turning him into a ferret and bouncing him up and down] My father will hear about this!
Professor Moody: Is that a threat?
[He steps forward, and Malfoy runs around the tree, Moody following]
Professor Moody: Is that a threat? Is that a threat?
[Malfoy flees]
Professor McGonagall: Professor Moody! Professor!
Professor Moody: [yelling after him ] I could tell you stories about your father that would curl even your greasy hair, boy!
Professor McGonagall: Alastor!
Professor Moody: It doesn't end here!
Professor McGonagall: Alastor, we never use transfiguration as a punishment. Surely Dumbledore told you that?
Professor Moody: He might have mentioned it.
Professor McGonagall: Well then. Do well to remember it!
[She stalks off, and Moody makes a face at her retreating back]
