Henry flicked his eyes towards the two Third Years who didn't wait their turn to speak but it was quickly revealed they weren't answering the Professor's question, just voicing their own thoughts. He knew Professor Lissington wouldn't punish them for talking out of turn, in fact he rarely gave out punishments at all. Overall a very easy going Professor compared to some of the others and Henry did like him. There was an air of fun around him which made it easy to just be himself while in class.

He remembered the last creatures the professor had brought into class, the whole Hinkypunk incident had been both fascinating and scary, especially after the Professor knocked it off his desk and the hinkypunk's lantern broke and spread flaming oil all over the place. Despite the danger of being burned in the fire, it had been a very interesting class and a fine lesson on being careful not to knock over lanterns, whether held by a hinkypunk or just setting on a table.

When Professor Lissington called on him to answer, Henry smiled. "Thank you Professor. I believe the Grindylow's are classified as double X, which means they aren't considered dangerous to wizards."
