Hmm. Ethan finally understood why the room had been made so messy. He decided to start on the area around his desk. "Scourgify!", he said to the floor. "Scourgify!", "Scourgify!, "Scourgify!" he yelled at various parts of the floor, walls, and corners of the seemingly dilapidated room. Most times the dust and grime came right off but sometimes it took a few Scourgifies to get that section. Ethan thought this might be taking advantage of the students but he quickly realized that the room had purposely been made dirty. Concentrating on the work at hand, Ethan carried on.
