"[as he roughly releases the scythe] Pick up your wand, Potter! I said, pick it up! Get up! Get up! [Harry gets his wand] You've been taught how to duel, I presume, yes? First, we bow to each other. [he bows, Harry does not] Come on now, Harry. The niceties must be observed. Dumbledore wouldn't want you to forget your manners, would he? I said, BOW! [uses a curse to make Harry bow] That's better, and now: Crucio! [Harry writhes on the grass in pain] Crucio! [the curse is lifted] Attaboy, Harry! Your parents would be proud. Especially your filthy Muggle mother!"
