It's normal to thank someone for their help, isn't it? It doesn't matter if it's big or small.

[Plus, he didn't have much time to thank you about 'borrowing power' earlier, but he feels like he should probably not bring that up again.]

I hope you didn't get dragged into... whatever that circus was about. How badly do you need to mess up to earn a curse by a fox god that lasts for years....
