One thing I'm really glad season 6 is doing is showing different family dynamics and that not all families are loving and supportive, so many young people out their are going through circumstances with their families that only ever seem to be getting worse, but amidst it all, we get to see that these characters try to face a hard line many people would rather not face, which is that they are not responsible for the things that hurt them in their childhoods, but they are responsible for what they can do with their lives now.
Nino has a mother and father who no longer share the same love for each other they had in the past, they fight every day, letting their emotions run wild, unable to cooperate to make a decision together and failing to see that their children are in the room listening to every word they yell out. Nino dislikes that his parents fight, but he had fallen into a state of denial over the relationship between his parents, wanting to believe they still love each other as he carries the heavy burden of shielding his little brother from the fear of their parents possibly divorcing, all the while struggling to deal with it himself too to the point that he quickly projects his fears onto his own relationship with Alya. Nino was so afraid of one little argument potentially leading to a lifetime of discourse that he was willing to pretend to like everything Alya likes to avoid arguing, feeling that despite not having any control in helping his parents get along, he does have control in connecting with Alya and in turn helping his friends connect better to never fall down the same path as his parents. However, by the end of the episode, Nino comes to the sad realization that he needs to let his parents' relationship run its course and let it end. As disheartening as it was for him to not be able to help save his parents' relationship, what was happening between his parents was never his or his little brother's fault and neither was it their responsibility to fix. While they would have loved for their parents to work things out to stay together, it was only when they remained tied to one another that they were becoming terrible people no one in the family liked. It wasn't until his parents were finally agreeing on one thing, to divorce, that Nino noticed some stability returning to the house, choices were being made, plans were being set and although it would take him and his brother getting used to going back and forth between his mother and father, at the very least he can feel at ease in knowing he could finally leave his room without hearing arguing on the other side of the door.
Ivan has a father with a deep criminal and supervillain background, his mother did too, but despite not agreeing with what his father said or did throughout his life, Ivan was kind and couldn't help but still have love for him, visiting him in prison when the opportunity came along, but all the while wishing his father could have followed a better path to be the parent he wanted to look up to as a role model. As much as Ivan did not like his fathers idea of taking advantage of Ms. Bustier's program to steal the Mona Lisa, saying no was difficult considering crime was the only way he could connect with his father and that such a refusal was essentially him talking back to his dad. Sure the heists failure and the heroes reasoning over Raul's akumatization allowed him to stay in Ms. Bustier's new chance program, but it was Ivan who came to the realization that it was ok to not easily forgive his father for being so selfish and nearly ruining the program that would give him a chance to leave his life of crime behind, a program no doubt many people in prison were also depending on to get a fresh start and build better lives for themselves. Ivan will always love his father, but at the end of the "El Toro de la Piedra" episode, Ivan accepted that his dad had to be left to take responsibility for his own problems and promises. Despite being family, it was ok to put some boundaries in place between him and his dad, that being that he will always love his family, but their families cycle had to end, and it would end the moment Ivan decided to step away from his parents shadow and not participate in the chaos they were used to living in. While that choice made Ivan seem like a villain to his father, a weakling who abandoned his family at a time he was asked to do something, in truth it meant Ivan was stronger than his father and all those before him in the family ever were, by making the choice that following his own gentler path meant his parents were not the ones in his life to look up to.
Kagami came to learn of one very cruel fact of life, that not all children are born because their parents wanted a child to love. Kagami grew up with all the money and resources in the world, she was given an education not many are able to have and the way she carried herself with such discipline and manners made her seem like the perfect daughter any person would want. But exitence alone in her family was measured by perfection and the more Kagami noticed other families carried each other with love and support, always willing to be there to give hugs to show that they cared, was all the more Kagami realized love didn't exist in her family and may not have been present when Tomoe used the peacock miraculous to create her. Tomoe wanted a child to fulfill her own selfish desires of having a perfect child that would not be like anyone else, a child that would uphold the family name the way she intended, love had no place in their training or the lessons Kagami was taught. Kagami may still want to try and talk reason with Tomoe to convince her to change her ways, but the more Tomoe continues to be set in her ways, the more Kagami realizes that the best thing she can do for their family and herself is to treat herself as someone who wants to carry a loving heart and not be the trophy her mother wants to show off. At the end of "The Dirtifiers", Tomoe believed that Kagami only accomplished creating such a giant storm to cover all of Paris because it was thanks to her strict training and education pushing her past her physical and mental limits, but it wasn't, it was because Kagami received the love and support of friends who considered her family that gave her the motivation to push past her limit and make that storm, helping her realize that although she can't choose the family she was born into, she can choose who in her life to consider her loving family.
