[He's very pleased to get such a good laugh out of Childe, having to fight it to stop himself from laughing along. Listening to his companion tell his, he wonders if this story is half true- hilichurls tend to take over people's camps if left alone...]

Oh, goodness. I can see why you have your hands so full as a Harbinger...

[He responds with a smile, amused at the idea of two Fatui soldiers being that dumb. He can see why Childe's amused with it.]

But, I have to come clean with you. My "story" was really just a set up for that final punchline. That didn't actually happen to me, and you can modify it any way you want to make it fit when you tell it. You just have to make it sound believable until the end, hehe.
