Cassandra came in with one of those horrid contraptions... a broom. She handed it to the girl. "I want you to fly around this room on this broom and hit the bludger." She said pulling a bludger out. The broom was charmed to fly up and buck until it's rider would fall, the bludger was charmed to hit the girl's limbs. "Oh... you may notice I don't have a bat... and neither do you." She smiled. "Have fun!" She said and left.
