Kace made the eyebrows when the professor mentioned them being sissy's if they didn't wanna drink the potion. That sounded like a challenge. Challenge accepted professor. Especially if the professor was new, he didn't know who he was dealing with. Then he heard the professor's question and Kace smirked. He raised his hand and said,

"Hmm...maybe they wanted to get in touch with their inner dragon?" he suggested to the professor. "But i think the people who would use it would be the fire breathers you would see in like...circuses and such."

This lesson was getting interested by the second. Kace couldn't wait to start it. He wanted to breathe fire.
