Then they were friends once. Or rather, on friendly terms, which isn't always the same thing. Rinoa may not always be good at 'making nice,' in spite of whatever attempts she makes, but she does understand there's a difference between making nice and actually being nice or thinking of another with a particular set of niceties in mind.

She suspects that she doesn't need to try applying that to Loki, of all people. He's older and while she doesn't subscribe to the newsletter that elders are necessarily wiser, just a few conversations with Loki and she's willing to agree that he is probably smarter and more worldly than she is.

"Oh, so you're not even..." They're not even actually related. Rinoa's expression falls before she can prevent it from doing any such thing. But after a moment's consideration, she reminds herself that he doesn't want her pity and she owes him better than that. In consequence, she straightens up, and the features of her face resume something akin to Rinoa Normalcy. "I see. That sounds hard. Do you sometimes wish he was here? I know it might be silly to think like that, but there's always that possibility that he'll show up here. If he did, maybe you guys would be able to rekindle something from your past. If it was what you wanted, anyway."
