[Aether can see how stressful it was for Childe. He's not surprised at all. His poor knight could lose his life if things went wrong. The prince reaches out to pat the other's shoulder. That's the most he can do as long as they're on their horses.]

We both owe her... But also I spoke with my father. I have sworn with my life that Elise's happiness will be most important to us.

[His smile is tiny, but there's no happiness in it.]

If something goes wrong and my father would want your head... then he'll have mine as well.

[What would be Aether's life without his knight, anyway? If Childe was to die, then Aether would follow him.]

As for how to defeat the princess... [He perks up.] How about we try hunting boars?
