--Kiera--
Kiera was the first to hear the screams. She whipped her head around to see Bonnie, the girl she had met earlier, floating up above the Slytherin table. Long chains snaked up from the table and started to encase her. Kiera looked down in complete horror to see where the chains were coming from. Célia. The Spanish transfer girl. The chains tightened around Bonnie. She began to writhe against the heavy metal that was now strangling her. Kiera glanced at the teachers. They noticed nothing at all, carrying on with their normal conversations. Kiera couldn't take it anymore. She pulled out her wand discreetly and muttered "Reducto," The chains broke off of Bonnie and she crashed down onto the table. Kiera stood, grabbed a slice of pie, and ran as fast as she could to the girls' bathroom.
--Tomie--
It was Bonnie's fault. Bonnie didn't mean it as a joke. She was being real. But nobody jokes with Célia, especially not around Tomie. They exchanged looks. Célia nodded and pulled out her wand. Bonnie started floating. Tomie laughed. Bonnie began to scream as chains entangled her. She stayed like that for a little bit, until a spell came flying into the chains, breaking them and causing Bonnie to fall onto the table. Soups and bread flew into Tomie's face. Tomie shrieked in utter disgust. She was trying to make a good impression on everyone. But now she would be Soup Girl, or Lover Girl. She heard a commotion across the room. It was Kiera, tucking her wand into her pocket and running out of the room. Tomie stood up and began to chase after her.
--Célia--
"Tomie, wait!" Célia called after her. Tomie kept running. Célia sighed. She turned towards the teachers. Strange words drifted off her tongue and the teachers froze. They wouldn't be moving for a while, if ever again. She felt a sudden pain coming from her brain. You are the headmaster now. She gasped. She had all the power now. Célia strutted to the podium. "Hello, students. I am your new headmaster. If you wish to join me, please do so." Most of Slytherin house, beside Bonnie and Beau stood slowly and began walking to Célia. Célia was diappointed. "Join me, or die." She screamed. A few students from different houses stood up and scurried to her. Beau stood. "I would rather die than join you. You think you can do everything you want and run this place. Bulls***! Complete Bulls***!" With an earth-splitting roar, Célia cast a powerful spell. He was pushed into the back wall of the Great Hall, slamming hard and hurting himself.
--Giselle--
This was crazy. The wierdest thing Giselle had seen. And as she watched Beau hit the wall, she let out a little shriek. Giselle decided that now was the time to be brave. She ran to Beau. Conjuring up a strecher, both she and Bonnie helped him up into the stretcher. They ran him out into the nearest room- the girls' bathroom. Then they got a good lot at his injuries. He was bleeding on the back of his head, and bruises were forming on his back. "This is going to hurt," Bonnie whispered. "Shhh..." Beau just groaned, silent tears falling onto his face. Bonnie and Giselle grabbed paper towels and bandages from a stall when Giselle heard something. All the way down on the other side of the bathroom, she heard sobs. Giselle didn't worry. People cry a lot. Besides, Beau was the top priority right now. And hiding from "Headmistress" Célia.
