Ahaha, how could I forget? You were that way from the moment we met. [ So compassionate and yet so deadly; it's quite a dichotomy, and Childe can't help straying close, trying to figure out what makes him tick. ] That's why... some things are better left unsaid. I have no taste for deception.

[ So it's better if Childe doesn't reveal too much, not about his family or his allegiances or what'll become of them both at the end. When he eventually rushes for the Traveler's jugular, like he can conquer Aether like he means to conquer the world, there won't be any room for kindness. ]

If I catch you out in a lie, we'll have a reason to fight again. When that time comes, I want you at your strongest.
