She and Volo could have banter related to your point in the story as a gentle reminder of where you left off. They could be talking about how Volo is going to write about your exploits and make snarky comments about your choices. They could also gossip and judge the MC horribly for whoever they chose to romance (or the drama of the MC sleeping with multiple people!)
You could see their unlikely friendship develop over the course of the game. Like he calls her his "little muse" and she adamantly demands he sing her lullabies to sleep.
OK this sounds absolutely adorable and I approve.
