[He returns Aether's glare with an innocent smile, as if he were ever capable of such a trait.]

Childe, [He quickly answers the princess, bowing his head towards her with respect, keeping the sweetest smile on his features. He will fail to mention his relation to Aether- on purpose.] It is a pleasure and an honor to finally meet you. I've heard much about you before your arrival, and I hope that you find your time here acceptable. Let me know if he gives you any trouble, princess.

[He says with a wink, cheerful and full of chaos beneath the surface. There was no way he wasn't going to be front and center during this dinner, as if this is the only way he could think of to deal with the situation without destroying something somewhere else in the castle. Besides, he likes it.

So he's going to make sure he'll make the most of it tonight.]
