Given the look on Nathaniel's face, he didn't get Kir's sense of humour. He wasn't exactly surprised. Purebloods weren't well known for encouraging kookiness. It didn't matter to him. He amused himself.
“I see. I'll do my best then,” he nodded, when Nathaniel warned him not to be informal with his cousin. Frankly, Sylvia Mordue was going to have to take him as he came, although a vision crept into his mind of himself sweeping off a top hat and announcing that he deeply regretted having to inform her of Master Nathaniel Mordue's current state of ague. It was amusing enough that he almost wanted to do it, but he didn't make fun of people. However, nor was he going to put on airs and graces he didn't possess. Still, there was no point arguing that out with Nathaniel or making him worry. He glanced at his watch. “I'll tell her in the morning?” he suggested, seeing as it was only about an hour until curfew, and Nathaniel seemed like he was likely to be given an early night.
Nathaniel had managed the Healer's questions, and didn't seem to be much beyond sleepy and confused, so Kir figured it was fine to leave him.
“Hope you feel better,” he wished him, heading out.
