Ethan walked up to the third floor corridor. Wow. This place could really use some cleaning. It was a good thing that Professor Knox had taught them cleaning spells last class. Ethan eyed some other students cleaning with, were those vacuum cleaners? He walked over to an untouched part of the room. "Scourgify!", he yelled at a cobwebby area. Ugh. Spiders. "Deletrius!", he said, pointing at a group of those disgusting vermin. He felt a lot better, now that the spiders and their homes were gone. No time for dillydallying, there was work to be done. "Poliotus!" he said to the area that he had cleaned. Ah. Squeaky clean. Just how he liked things to be.
