When Katarina invites Arte to a meal, it’s more than just servants preparing everything for them. Katarina is in the middle of everything, working hard with the help, and not thinking of them as mere servants. Arte’s never seen her more happy. What gets Katarina down is the prospect of returning home to her parents’ house, which has never felt like home to her, so how can she be happy there?
A large part of that unhappiness stems from Katarina’s disgust for the nobility’s inclination towards always wanting there to be a clear difference between themselves and poorer levels of society. Her egalitarian attitude was developed by osmosis when she was raised far from Venice by her wet nurse Buona, who had a son Gimo with whom Katarina was close. When Buona suddenly died (as people did with far more regularity back then) she was thrust back to Venice, separated from the only home and family she knew to that point.
Yuri tells her about Katarina’s past in order to contextualize his opinion on the matter: Katarina finding her happiness depends on her ability to accept that she’s in the place she’s supposed to be, where that happiness is to be found, and that moving forward is the only way to find it. Even so, Arte can tell there’s a serious lack of closure, so she offers to take Katarina to see Gimo.
As Arte observes how both Katarina’s parents and servants act around her, it becomes clear that no one is really looking at the girl. When she overhears Malta complaining about how expensive her dowry’s going to be, and Sofia not challenging him, Arte recalls how her own parents argued spiritedly about her. The difference is, while they disagreed on the details, they were arguing for her sake.
Yuri tells Arte that Gimo is on Murano Island, and maintains his utmost faith not in her, but in his decision to choose her. It’s an interesting distinction, but Yuri didn’t become the rich and successful person he is by doubting his instincts.
On the island, Gimo regards Katarina coldly, but mostly out of deference to his mother Buona, who told him he couldn’t have any more contact with Katarina, since she was a noble. Their being a family was a beautiful dream, but that’s over.
Gimo tells her that there are times when he has to do things he doesn’t like, but because he was able to face forward properly and move on, he knows Katarina can do the same. When she does, he’ll look forward to welcoming her back with a smile.
Upon returning to Venice, Katarina ends up in bed sick for three days, and Arte is dismissed by Malta for failing to live up to her expectations. However, Katarina appears before her parents, performs all the requisite aristocratic gestures perfectly, and begs them not to fire Arte.
While Malta and Sofia are shocked to see their daughter behaving so properly, Malta still bristles at the idea of changing his mind, until Sofia, her hands trembling, speaks up and offers her opinion to her husband for the first time, agreeing that for Katarina’s sake, keeping Arte around is best.
Katarina’s home was a house of closed hearts, but thanks to Arte’s sentiments on doing things for someone’s sake, Sofia and Katarina’s hearts are now open. Like Arte, Katarina is a modern young woman with modern ideas, and they’re steadily learning together the ways to strike a balance between their modern values and the customs and obligations of their class.
