...WHAT?!!!!

Derry stared at this boy, a very clear expression of disgust on her face. How could someone churn out THAT? "Sir..." she said, looking between the other kids. "This guy is lying through his teeth, and I'd be happy to take a truth serum to prove it." Because she'd literally do anything to prove herself right. Especially right now. She was only just holding it together to stop herself from punching the kid in the face. "And if you know anything about any of the three of us, sir, you know we wouldn't do that to someone." At least... she or Bev wouldn't. Derry didn't know Jeremiah too well. But she was willing to bet that if he was friends with Beverly then he wasn't the kind of guy to purposefully exclude someone else. "Slytherins usually stick together." THAT was a jab at this guy who thought he was better than all of them, clearly.

After a glance at her watch, she added something... "I need to add my snake fang, sir. I'll be back here in one second."

She quickly stepped back behind her desk, glanced into her cauldron and added the snake fang. There... now what?

Oh...

She should probably go back over there. Derry walked over to the professor again and waited for the verdict.
