Hendrik wasn't going to pretend he wasn't worried, and Yotsuyu's coughing certainly had him feeling it. But he looked around at the others then and shook his head. "We should get you and your students out of the building." Priorities for him had her going out the door first and foremost. But he wasn't going to drag her.

Hearing her going on about pranks and then tables just had him frowning. Right now the knight didn't care about who did it, because that was going to come later. And if she requested his help, she would most definitely have it. This made him angry of course, not at Yotsuyu, and not her students, but to those who would harm innocents and since she was his friend, that went without saying.
