Lawliet's face dropped as the girl somehow managed to make the dummy's eye pop out, set something on fire but couldn't get an easy spell such as Depulso down. He thought for a moment before speaking again.

"Um Diane, maybe it's better that we do something else instead. You asked about a way to fix these things, right? Well the incantation for it is Reparo and it's just a simple wave of your wand," he spoke slowly, while demonstrating. The Slytherin boy pointed his wand at the curtains and muttered Reparo!, and the curtains looked brand new again.

Surely nothing could go wrong when using a spell to repair things... right?

"There, now you try it with the dummy's eye," he said, encouraging her. "You'll get it down eventually and then we can go back to practicing Depulso. At least this way you'll know how to fix things if you were to break them again," Lawliet added and gave her a small wink.
