Caleb laughed, "No one's getting hurt." He shot his classmates a look then added, "Yet." If anyone were to happen upon them they would be severely punished for their actions especially if it had been Professor McGonagall. He couldn't do anything severe, though he wanted to, and racked his brain through all of the spells, hexes, and jinxes that he'd gone over in the Dueling Club.
Mid-thought Caleb found himself flying through the air. He had a split second to think and then his head smacked against the corridor wall. Hitting the floor he felt a warmth trickling down the back of his neck. Reaching a hand behind him he touched his scalp, his fingers coming back around covered in red. Blood. "You've started something you better be able to finish Weasley!" Caleb yelled, the other students around him changing expressions from slightly intrigued to borderline frightened. Striding back toward Hugo his wand was aimed directly at the other boy's face, his eyes burning and his hands shaking. "You fucking blood traitor! Furnunculus!" he knew he was going in a direction he couldn't come back from, but hopefully a few boils on Hugo's face would get his point across.
A few other students around him seemed to have been hit with the remnants of their spells and were itching to get their way up to the Hospital Wing. Salazar willing, Hugo would have to go there as well.
