Evan sat down some desk as the girl said she studied Arithmancy. That was a hit lesson, and a hard one as everyone seemed to be studying it. But he had done it, and given it to the professor. He was lucky to understand the lesson, thanks to his father, he was trained well. He opened his mouth to say that he'd already finished when a very familiar voice came behind him. He instictively raised his hands to protect a potential blow again, but Lyra did nothing and merely talked to girl. It was odd of her, but apparently she didn't think Evan was up to anything bad or mischievous. Or it might also be because she didn't feel well today. Evan guessed it was for that matter. She tended to smack him whenever he was with a girl.

Now pretty sure that no blow was coming, Evan relieved obviously and jumped in the conversation. "I've done my homework." he said, nodding. "I think I understand it..." No he was sure he understood it, but he was being modest. "I can help you if you need help." He'd actually be happy to help. He felt like he was useless to Slytherin.

He was so into explaining Arithmancy that he forgot to introduce himself. Slapping his head sarcastically, he said "I'm Evan Cartwright." and smiled, turning his blue eyes to the girl.
