Edward watched his comrades taking large chunks from the floor, but there was indeed some debris laying about. He decided to take some initiative and help get it out of the way as it was brought up. He walked on the side of the group, opposite the area he was looking at. He didn't want to block the door, so he chose and area adjacent. He pointed his wand at the debris pile and spoke the words Depulso! and watched as a pile of debris began to move away from the group. When it had gotten close to the wall, he went back and did some more, to clear the debris and make way for more. He had considered just causing it to be banished, but he didn't know if it would be used again to fill in the space and he didn't know where it would end up.
