Duel #1.
Carl had been looking forward to this! The Dueling Club was fun and even though he almost never won, he had signed up again this term. He thought his magical abilities had improved quite a lot, thanks to the experiences he gained from the duels. He was hoping he got to learn new stuff this year as well.
... However, the Hufflepuff was not hoping to get paired up with a girl again. He felt bad having to jinx girls, and he barely knew Cassandra.
"Hi," He smiled at the Ravenclaw as he bowed, then pulled out his wand from his pocket. He started running through the list of spells he had in mind, before choosing one that he felt comfortable performing.
Raising his wand, he cast the Ears to kumquats spell at his opponent. He almost grinned at the memory of getting hit by this spell in a duel when he was a First Year.
