By this point, so soooooooooo close to the end of the lesson, Toby's fidgeting and moving around had gone up a gear. He'd been writing and focusing for so long that trying to think of correct, or at least logical, answers for the questions was hurting his brain. By this point he was answering with the first thing that came to mind, whether or not it sounded right.

Like right now, Toby raised his hand, aaaaand...

"The person making the potion," he supplied, fingers waggling in the air. "Potion can't be made without the witch or wizard there to make it."

Boom. Genius.
