Well, their relationship could develop in a rather unexpected way. Maybe Danny initially tries to avoid Haery because he's scared of what the Master of Death represents. But then, when Danny gets into a really tough situation, Haery comes to his rescue. This act of kindness could start to break down Danny's walls. As they spend more time together, they might discover that they have complementary skills. Haery's knowledge of death - related magic and Danny's ability to handle difficult situations in the living world could make them a great team. And as they rely on each other more and more, their relationship would grow stronger, evolving from distrust to trust and then to a strong friendship.
One possible plot twist could be that Haery, as the Master of Death, has some hidden power that he unknowingly passes on to Danny. This could change Danny's character arc completely. For example, he might gain the ability to see the spirits of the dead more clearly or even communicate with them in a different way. Another plot twist could be that there is a prophecy about the two of them working together to defeat an ancient evil. But they initially don't get along and have to overcome their differences to fulfill the prophecy. A third plot twist might be that Haery's connection to death somehow causes Danny to be in a state between life and death, and he has to figure out how to get back to his normal state while also dealing with the new powers or insights that come with this in - between state.
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.
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.
Eventually, their relationship could be one of deep respect and admiration. Temari would see Naruto as not just her master, but also as a role model. Naruto would be proud of how far Temari has come under his tutelage. They might even end up being important allies in future battles, with a relationship that is based on both professional respect and personal friendship.
Their relationship could start off rocky. Snape might be cold and distant at first, seeing Harry as just another responsibility. But as he gets to know Harry in his pet form, he might start to notice Harry's unique qualities and grow fond of him. For example, Harry could show loyalty and courage even in his pet state, which would gradually change Snape's view.
It can develop in various ways. It might start as a hostile relationship, with Dash bullying Danny as usual. But as the story progresses, they could find themselves in a situation where they need to cooperate, like when facing a powerful ghost. This shared experience can gradually turn their relationship into one of mutual respect.
It might start off rocky. Damian, with his strict upbringing, might find Danny's more carefree attitude annoying. But as they face threats together, like a powerful ghost attacking Gotham or a villain targeting Danny's family in Amity Park, they would start to respect each other's abilities.
Vlad's relationship with both Danny and Dash would be complex. He might initially view Dash as a tool to get to Danny, using Dash's aggression towards Danny to his advantage. As for Danny, Vlad has his own twisted reasons for wanting to control or defeat him. However, as the story progresses, Danny could start to see through Vlad's manipulations and try to turn Dash against Vlad too. So, the relationships would be in a constant state of flux, with power dynamics and personal growth playing important roles.
However, there could also be a glimmer of the old relationship. Maybe deep down, Evil Danny still has some feelings for Sam, and she tries to use that to her advantage. But it's a dangerous game, as Evil Danny could easily turn on her. This complex mix of emotions and power dynamics would make their relationship very different from what it was when Danny was good.
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.
