Caleb heard the crowd around them growing more and more on edge. People were beginning to call down the corridor for help and he could see two Prefects standing near the group of students closest to him. He could feel his stomach lurch. Things were going to go downhill fast. Looking back up at Hugo he heard the disarming spell as it sped through the air then cracked as it collided with his furnuculus. His smile grew a bit wider as he noticed the boils on Hugo's arm - he wouldn't get out of this completely unscathed.
The noise quickly escalated as Caleb shot a confundus charm into the mix aiming for Hugo, but missing by a mere few inches. "Done yet Weasel?!" he called over the shouting. Encouraged by his house mates Caleb pushed his way through the now compact group of students to try and get to the Weasley boy. He didn't know what he'd do once he got there. Maybe throw a punch, but he stopped short when he heard a loud, shrill voice coming from just ahead of them, "SILENCE!" McGonagall. Everyone stopped.
"What in the name of Godric do you think you're doing?" she asked, grabbing both boys by their shirt collars and dragging them away from the mass of students, "And the rest of you get to class!" Slowly the kids crept away from the Headmistress and the two culprits, some heading toward the Hospital Wing others to hide around the corner and eavesdrop. "Fifty points from each house, and detention. For both of you. I think two weeks should do it. You'll be spending it with Professor Slughorn cleaning cauldrons and preparing ingredients. If you don't show up you'll be even sorrier than you are now," she had her hands on her hips and her glasses clung to the edge of her nose. "Well? Scoot! Off to class! And if I hear another peep out of either of you it'll be another two weeks worth of detention!" She strode quickly down the corridor back to her classroom and gave them one last warning look.
Caleb frowned at Hugo, "Next time you'll be sorry. McGonagall won't always be there to 'Save the Day'." His eyebrows were knit together in frustration and he took little pleasure in the oozing boils on the other boy's arm.
