[It's a smile that Aether himself mirrors. While he can't deny some part of him is itching to ask now just how well he knew other Aether to have addressed him the way he did (and perhaps, by extension, how well he knew the Lumine he remembers in Teyvat), for now, he'd rather focus on what's in front of him. And so, he nods.]

Of course, I'd be happy to! And... if you don't mind the differences in timelines making things a little strange-- I'd love the chance to get to know you again.

[It's a strange thing, really. The Zhongli in front of him should be more or less exactly the same as the one he remembers. Likewise, they both remember the same events, and bonded in the same way... just with Lumine, instead of Aether. But perhaps that meant it would simply be easier for them to become friends again?]
