Harry walked out to the center once the dance show was over. He was impressed by it the dance would be good for distractions in a fight. He looked at everyone and said "I'm Harry I can control water and light." To show this he pulled water out of the air and made 3 small spheres with it. Be spun the spheres of water around his hand. He then made all the lights in the room go completely dark. He waited for 2 minutes then returned the lights to how they were. One he was done he walked back to the wall he was leaning on still spinning the water.
