Jealous? [Her embarassment helps, but it does make him look over at Yona as well. He hadn't considered before that she might be attractive - he'd been so distracted by other things going on - but Kaya talking about her with such a complimentary air... It does stick with him.]

I get that she's a good person, especially to host something like this. [Then he turns back to Kaya, shaking his head.] I think they really are just friends though. Zeno seems kind of... determined to be devoted to people in general? He refused to leave me alone when we first met too, until he was sure I had a temple and a god and a roof over my head. Even after that he kept checking up on me.

[Hopefully that helps...?]
