[Childe's eyes widen. Oh, that was not what he expected Aether to say, but he is beyond pleased with the concession he's made for not bathing with his knight.]

Now, I wasn't expecting such a...saucy response from you, Prince Aether.

[Using his full name and title to tease him a little further, enjoying the blush across his face. How cute, he thinks, that the prince gets so flustered by his direct advances like this. He'll just continue to do so until it doesn't work anymore.]

What plans do you have? Could I be privy to them? Or should I come up with my own creative ideas? Oh, how I'd love to know...

[Childe lets a finger play with Aether's braid for only a moment before he pulls it away, grinning like a little kid.]
