[Diluc doesn't light up in quite the same way that Aether does - it's not in his nature to do so - but he visibly relaxes a bit now that the elephant in the room has been addressed. There's still a long way to go in getting to know Aether, but at least they can do so with minimal anxiety.]

I take it Paimon is not here with you?
