"Potter against Malfoy, Granger against Bulstrode. Now, bow to your opponents!"
Of the four, only Hermione did as Lockhart instructed. Bulstrode raised her eyebrows in acknowledgment, while Harry and Draco stared unblinkingly at each other.
Lockhart did not correct the young wizards. He shouted, "Very good! Now raise your wands. When I count to three, wave them and say 'Expelliarmus.' Duelling tests how quickly you cast and how swiftly you respond to magic. Remember, use only the Disarming Charm. I don't want anyone getting hurt."
"One... two..."
The moment Lockhart reached "two," Draco launched a sneak attack. A flash of red light slammed into Harry's head like a frying pan. He staggered back several steps before barely regaining his balance, then struck while Draco was sneering triumphantly.
"Rictusempra!"
A silver light struck Draco in the stomach, forcing him to lie on the floor, gasping for breath. Ignoring Lockhart's protests, Harry fired another Tickling Charm at him.
Draco laughed so hard he could barely breathe. Once the tickling on either side of his ribs subsided, he swiftly retaliated.
"Tarantallegra!"
Harry lost control of his legs. His muscles tightened, and he broke into an extremely lively dance.
"Stop! Stop at once! Before the duel began, I told you to use only the Disarming Charm. If you two keep this up, we won't be able to keep the Duelling Club running!"
Lockhart tried to reason with them.
Snape shot the show-off a glance, drew his wand, and said "Finite Incantatem," lifting the Tarantallegra spell on Harry and taking control of the Duelling Club at the same time.
Meanwhile, Hermione and Bulstrode were locked in a fierce struggle. Both had abandoned their wands and resorted to physical attacks.
Millicent Bulstrode used her thick arm and solid rib cage to clamp Hermione's small head firmly
