““Malfoy glanced around. Harry knew he was checking for signs of teachers. Then he looked back at Harry and said in a low voice, “You’re dead, Potter.” Harry raised his eyebrows. “Funny,” he said, “you’d think I’d have stopped walking around….” Malfoy looked angrier than Harry had ever seen him. He felt a kind of detached satisfaction at the sight of his pale, pointed face contorted with rage. “You’re going to pay,” said Malfoy in a voice barely louder than a whisper. “I’m going to make you pay for what you did to my father….” “Well, I’m terrified now,” said Harry sarcastically. “I s’pose Lord Voldemort’s just a warm-up act compared to you three — what’s the matter?” he said, for Malfoy, Crabbe, and Goyle had all looked stricken at the sound of the name. “He’s your dad’s mate, isn’t he? Not scared of him, are you?” “You think you’re such a big man, Potter,” said Malfoy, advancing now, Crabbe and Goyle flanking him. “You wait. I’ll have you. You can’t land my father in prison —“ “I thought I just had,” said Harry. “The dementors have left Azkaban,” said Malfoy quietly. “Dad and the others’ll be out in no time….” “Yeah, I expect they will,” said Harry. “Still, at least everyone knows what scumbags they are now —“ Malfoy’s hand flew toward his wand, but Harry was too quick for him. He had drawn his own wand before Malfoy’s had even entered the pocket of his robes.””
