After marriage, their relationship may develop in many ways. They could start a family together, which would bring new challenges and joys. Danny could teach their kids about the Ghost Zone and how to use powers responsibly if they inherit any. Sam would be the one to instill good values in them. Also, they might travel more, exploring different parts of the world and the Ghost Zone, which would strengthen their bond as they face new situations together.
One way their relationship could develop is through communication. Since they come from different backgrounds, there might be some misunderstandings at first. But as they talk more, they understand each other better. They also start to take on joint projects, like building a safe haven for friendly ghosts in the human world. This not only helps the ghosts but also deepens their connection as they work towards a common goal.
They would likely support each other's hero careers. Izuku could offer Momo advice on combat based on his own experiences, while Momo could help Izuku with strategic planning using her intelligence. Their relationship would grow as they face new villains and challenges together. They might also start a family, with Izuku teaching their children about being a hero with a heart, and Momo teaching them about using their brains and powers effectively.
Their relationship could develop with them sharing more secrets. Since they are now married, Shinichi might feel more comfortable revealing some of the darker aspects of his detective work that he previously shielded Ran from. They would also support each other more deeply in their respective careers. Ran could continue her martial arts training and Shinichi would be there to cheer her on, while Ran would be Shinichi's sounding board for his cases.
Their relationship could develop with them learning more about each other's dreams. Ash might support Serena in her new cooking business that focuses on Pokemon - friendly foods. And Serena could encourage Ash to take part in more international Pokemon battles.
In the lead - up to the wedding, they would have to work through a lot of issues together. Sam might help Danny come to terms with his role as a half - ghost in a more positive way. And Danny would support Sam in dealing with her family's concerns. This would strengthen their bond and make their relationship more mature and stable for the wedding and beyond.
Often, in fanfiction, conflicts play a big role in their relationship development. Maybe there's a new character who is interested in Danny and Sam gets jealous. This jealousy makes her realize her true feelings for Danny. And Danny, in turn, sees how much Sam cares and his feelings for her intensify. It's a common trope that helps to move their relationship forward.
Perhaps their relationship develops in a way that they become more like partners in crime. They could use the Christmas chaos to their advantage. For example, if there's a mean - spirited Christmas spirit causing trouble in town, they work together to stop it. Danny uses his powers and Sam uses her wits and knowledge, and this shared experience makes their relationship grow in a new and exciting way.
Their relationship could develop as they face challenges together. For example, if a new type of ghost - eating plant appears in town, Sam's knowledge of plants and Danny's ghost - fighting skills would make them a great team. Through working together to deal with this threat, they would grow closer and start to trust each other more deeply.
Well, usually they start as friends. They have common interests like fighting ghosts and standing up for what's right. They might share little moments of closeness, like when Sam patches up Danny's wounds after a tough fight. This builds a sense of trust and caring between them.
Their relationship could be portrayed as a partnership in parenting. Sam and Danny work together to teach their kids the values they believe in, whether it's about respecting all living beings (because of Danny's connection to the ghost world) or being true to oneself (which is something Sam has always been about). They also share the responsibilities of taking care of the household and making sure the kids are happy and healthy.
One interesting aspect is how they handle Danny's ghost - related issues as a married couple. For example, if Danny has to go on a dangerous ghost - hunting mission, Sam would be there to support him, not just as his friend but as his wife. She might use her knowledge of the supernatural and her quick thinking to help him out.
