Mischa was completely distracted in the class. He blamed Karina. She was sitting just next to him. He kept staring at her though he was trying his best not to. The staring did help because he saw when she whipped out her wand. He knew what was next. With a smirk he turned his attention away from her.

Mischa was about to respond to the Ravenclaw girl (Tora) who had approached him about the fire and about getting started. He had opened his mouth to ask her what about the other Ravenclaws. The problem was he was unable to utter a syllable. The Silencing charm. That must have been what Karina had used. Why not carry on the act to divert suspicion?

Mischa with his face twisted into a look of panic pointed to his throat. She was a Ravenclaw. She would be able to figure out what was wrong.
