While setting up the dummy, Kevin heard someone come in to the Dueling Arena and his gaze immediately turned to the sound. Seeing that it was ...whats his name.... he waved at him. He looked at the older guy again. The same way he had done in Diagon Alley. Judging. He was judging him whether or not he knew some good spells he could learn and use against the Professor. "Dude you came at a good time!" he said and pointed at the dummy he had set up. "Do you know how to duel? I NEED to learn how to duel and how to use spells AND learn how to defend myself BEFORE saturday."

It was slightly freaking him out how much he had to learn. But there was no way he was going to get defeated by that crazy space man. And hey? Maybe he turned out to be good at this? He rubbed his forehead where the date time and location of the duel was written and switched his wand in to his right hand and pointed it at the guy. "Well? Are you helping me out or not?" He only cared about his own practise.
