Oohhh so they were catching fairies? That seemed pretty cool and he didn't have a jar so he was glad the professor had them. He breathed a sigh of relief and went over and grabbed one. He got his wand out of his robes and and said, "Scourgify!" and then the jar looked cleaned. He went through the bushes with the rest of his classmates and wondered how hard it was gonna be to catch a fairy.
