[ Both of them have spoken of her before, and both hold her in very high regard. Ori has been delighted to meet others from Teyvat as a whole, but to meet the brother of someone who is important to Thoma and Diluc feels special - even if she has no idea how complicated this all really is, beneath the surface. It won't even occur to her. She simply thinks that Aether and Lumine must be far apart on the same realm and not... in alternate universes altogether.

She at least senses that there must be something more to this, given his silence, but she doesn't want to ask about it. After all... this topic is difficult for her, too, and much like Aether refrains from explaining the issue of there being two Teyvats, Ori refrains from mentioning that she had found her sister... just that she was very different, and had gone down a path that Ori was horrified to find her on.

(Surely, Aether couldn't relate to that, right?)

In the end, she smiles back at him. ]

And I hope you find Lumine soon, too. Who knows? Maybe she'll get pulled into this realm, as well. And it would be fun because there are already so many of you here! She'd feel right at home.
