[Childe can feel Aether's anxiety, wishing he could do something in this moment to relieve him of it. But the knight won't hide what had transpired in the hallway with the masked man, his shoulders falling as he steels himself to give him the even worse news.]

I'm afraid they're plotting to kill your father. And they forced me to agree to help them. I don't know why, since they seemed rather adamant that you'd become the king, but I'm sure their plans don't stop there.

[But at least with that, he can display a look of determination. He may of agreed, but he's no stranger to deception if he has to employ it.

Making sure they are still alone, Childe's hand comes down to tilt Aether's chin upwards, the blue of his eyes reflecting his own mischievousness along with that same determination.]

There's no need to worry. You know I won't let them have their way.
