[Childe isn't privy to every single thing the other Harbingers do- this including the attempts on Ayato's life. He's never ordered a hit on the Yashiro Commissioner, but he's not surprised that the other man initially assumed that he'd try to trick him into a place like this to kill him. But the reality is, Childe has no reason for it. But Ayato doesn't know that, and the Harbinger hardly blames him. Sounds like the Fatui have already tried to kill him.

But that's neither here nor there now. The Eleventh gleefully draws his bow at first, to have a little fun, to measure up Ayato and his fighting style. And the man does not disappoint him, as their fighting goes from testing the waters to a full out spar. He can tell there's a bit of frustration in Ayato's attacks, something he'd normally capitalize on if this were more than just what he called it- a friendly spar. But instead, Childe chooses to let those attacks sail towards him as he parries and counters with his own, letting him get all the stress out as needed. He wonders what it could be, if it were because he's Fatui or something else.

Throughout the spar, Tartaglia taunts and praises Ayato as he sees fit, laughter ringing out to signify how much fun he's having fighting him. He couldn't be more glad that the head of the Kamisato clan really wasn't holding back, a bloodthirsty joy worn on his features as they tangle with each other until finally, the two of them stand exhausted from their efforts.

The Harbinger lowers his weapons, as he feels is necessary to call this spar to an end since he's the one from an organization that isn't to be trusted, letting them disappear from his hands as he looks over to his opponent.]

Hahaha, shall we call it here? Goodness, it's been a while since I've been able to cut loose like that. We really should do this more often.
