[kaeya has handled many interrogations, in his time; kaeya is thus fairly certain that reim would be a tough nut to crack, hence kaeya's light laugh. with reim, maybe kaeya would have to forgo the usual tactics in favor of, like, ripping out the pages of his notebook one by one? leaving him handcuffed in a dirty, dusty room for a day. quelle horreur.]

We could easily put that to the test. How many secrets are you hiding...

[kaeya narrows his eyes, so serious—except just kidding, he's off duty Forever. it's more good-natured play-acting, just before he, too, joins reim in leaning against the railing. he doesn't care about whatever dust may or may not be there, but he does keep a few inches between them? they're close enough for, say, their arms to brush if they just barely lean to the side, and yet kaeya isn't infringing upon reim's personal space. he's being Respectful.]

But don't worry; I'll keep this one to myself. [and this is where kaeya should be offering up a secret of his own, but, naturally:] Though I am curious: did your duke discover what you did?

[he's stressin' that your, because you know he picked up on it.]
