Childe isn't used to how this place works yet and has no idea what they can and can't ask of that Peacekeeper thing. With a name like that, he already doesn't trust it. He doesn't trust a lot of people, though. He knows too many liars.

"I like the way you think!" he answers brightly. He doesn't care much how easily or quickly she agreed. He got the message on how you get ahead, so might as well jump in. Not having to convince someone makes it easier.

"You can call me Childe," he says, which is distinctly different from giving her his name. Still, it works! It's a name he uses much of the time, after all. "What do I call you, other than beautiful?"

He doesn't go in for needless flattery, but they are already playing a game here.
