Chapter 5: Malfoy's Challenge
"Having a last meal, Potter? When are you getting the train back to the Muggles?" "You're a lot brave now you're back on the ground and you've got your little friends with you", said Harry coolly. There was of course nothing little about Crabbe and Goyle, but as the High Table was full of teachers, neither of them could do more than crack their knuckles and scowl. "I'd take you on at any time on my own," said Malfoy. "Tonight, if you want. Wizard's duel. Wands only – no contact. What's the matter? Never heard of a wizard's duel before, I suppose?"
Harry thought quickly. He hadn't heard of a wizard's duel, but he didn't want to admit that to Malfoy. He also didn't want to get in trouble for breaking the rules if he could help it. He raised his hand and called "Professor McGonagall? Professor McGonagall?" Malfoy suddenly looked pale. "What are you doing, Potter? Scared of losing?" "I want to check we're allowed to duel, Malfoy, before I win," Harry said with a small smile. Professor McGonagall came down from the High Table. "Yes, Mr Potter, what is it?" "Malfoy just challenged me to duel him tonight, Professor. Is that allowed?"
Professor McGonagall's eyes narrowed. "It most certainly is not, Mr Potter. Ten points to Gryffindor for thinking before acting, and Mr Malfoy" – McGonagall spun round to look at him – "twenty points from Slytherin for challenging another student to a duel." Malfoy scowled at Harry and slunk back to the Slytherin table, followed by Crabbe and Goyle.
