[Yu's tense, and Chatterclock absorbs it more than he senses it, twisting his fingers through one another, watching Yu's hand for a moment instead of either of their faces. He blinks and comes to attention visibly when Nanako calls his name, but then his relief is instant and palpable, too. 'That's really cool!' He's so easy to please.]

Likewise, Miss Nanako. And thanks. I like my name, too.

[His eyes are still crinkled in his not-smile smile, though he doesn't look at Yu to give away the joke.

He holds one hand up like he's swearing an oath.]

I promise to be real quiet after curfew and not take fifty years in the bathroom. As conscientious a houseguest as I can ever hope to be. Any other house rules I should know about?

[He addresses it all to Nanako. Sorry, Yu, but Chatterclock can totally see who the real authority in this household is.]
