[Aether tilts his head slightly to the side.]

So which one is it? Are you saying you're lying? Or that I should trust you that you have no information to share?

[Aether sighs too.]

...Actually, I don't think you would lie. You have no reason to, because what would be your goal? There is no Tsaritsa here, no Fatui. We don't know how long we'll be staying here either... and who knows. Maybe my sister will show up here eventually.

[There really is not much Childe could gain with lies.]
