[wow. diluc's eyes widen a bit as the memories flit through their shared connection. there's a myriad of emotions that hit him all at once: protectiveness at seeing kaeya being so intimate with a man diluc himself has met but barely knows, surprise at seeing him in such an intimidating light considering diluc views him as a bratty little brother, annoyance that kaeya would be so mean to this woman for seemingly no reason other than being caught, and concern for the very same woman before him, practically trembling in fear at kaeya's underlying threat.

he tries to exude that concern, both in his thoughts and actions. it's not her fault she was very much in the wrong place at the wrong time. though he wonders how he'll scold kaeya for this without clueing kaeya off that he'd run into the woman who saw them.

his hands hover in the air as if in surrender or to placate, unsure of what to do with them. she's so frightened... he wants to comfort her, but would it be welcome? especially considering... well. the fact that he knows the very man she's afraid of.]

There's no need- your secret is safe with me. [a sigh... not at her, but at kaeya.] I apologize for his behavior. It was out of line - and it clearly had an effect on you.

He can't hurt you here. You're safe - breathe.
