Alex nodded and turned his attention to the front of the class.

"Good morning class!" Professor Tonks greeted. "This term, we will be working on the Dark curse, Injurious. Can anyone tell me what Injurious does?"

Alex raised his hand and spoke. "Injurious renders the victim paralysed for a week, given the time to say the incantation. If you just get the wand movement, you'll break the victim's ribs."

"Very good Mr. Cartwright! Ten points to Slytherin!" She paused. "Would you like to demonstrate?"

Alex nodded, and walked up to the front. "Injurious!" He shouted. A silver-blue light erupted out of his wand and sped toward the wall. When it hit, the stone crumbled.

"Excellent! Now for the rest of the class, I want you guys to practice the Injurious curse...You may begin. And try not to hit anyone!"
