You can also develop the characters through their relationships with each other. Maybe there's a family feud that gets resolved during the reunion. The way the characters communicate, argue, and make up can add depth to their personalities. Hermione could play the role of a mediator, which would show her diplomatic side.
The new family members introduced can be developed in different ways. Some could be eccentric, with strange magical habits. By showing how Hermione interacts with them, it can show her adaptability. For example, if there's an old aunt who is always mis - casting spells, Hermione's patience and helpfulness can be highlighted.
The family members themselves can also play a role in character development. Draco's parents, for example, could start off as cold towards Hermione but then be influenced by her intelligence and kindness. This change in their attitude could then affect Draco and how he views his relationship with Hermione. Similarly, Hermione's family, if included, could show their support for her new connection, which would give Hermione more confidence to explore her relationship with Draco further.
For Hermione and the Malfoy parents, at first there could be a lot of tension. But as the reunion progresses, they might find common ground. Lucius Malfoy might see Hermione's intelligence as an asset to the family rather than a threat. Narcissa could be more accepting due to Hermione's relationship with Draco. And among the extended Malfoy family, Hermione's presence could cause a shift in the family dynamics. Some younger Malfoys might look up to Hermione as a role model, while the older ones might be more resistant at first but gradually warm up to her.
The reunion can make Hermione more empathetic. Meeting her family members again, she'll understand their perspectives better. For example, if there were misunderstandings before, now she can see where they were coming from. It can also make her more confident in her own identity. She'll realize that she is a unique blend of her family's traits and her wizarding self. And it might make her more responsible, as she may feel the need to take care of family matters or preserve family traditions.
Obviously, Harry and Hermione themselves are the central characters. Their spouses, if they have any in the fanfiction, would also be important. Their children would play a big role too, as they would be part of the new generation of the family. And of course, old friends like Ron, Ginny, and other Hogwarts alumni might make an appearance.
In fanfiction, Percy and Hermione's characters can be developed in various ways. Some writers might explore Percy's sense of duty and how it interacts with Hermione's thirst for knowledge. For example, they could be on a mission together where Percy's strategic planning, which he learned from his time in the Ministry, combines with Hermione's research skills to solve a complex magical problem.
To develop Percy, you can focus on his loyalty. In a fanfiction with Hermione, this loyalty could be tested in new ways. For instance, when they are in a situation where they have to choose between their own worlds' interests. Hermione can be developed by highlighting her adaptability. She has to adapt to the new world of demigods, with its own rules and hierarchies. You can also show how their individual character traits affect their relationship. Percy's impulsiveness might sometimes clash with Hermione's careful planning, but they can also find a balance and grow together as characters.
For Draco, you can show his growth from his former self. He could be overprotective of the baby due to his past experiences, always fearing that the baby might face the same prejudices he did. With Hermione, her intelligence could be passed on to the baby in cute ways, like she starts teaching the baby simple spells very early. And as a couple, they can develop by learning to trust each other more in parenting decisions.
To develop Hermione's character in this fanfiction, we can explore her moral compass in greater depth. When interacting with the Lestrange brothers, she has to constantly make decisions about whether to trust them or not. This could lead to internal struggles that show different sides of her. As for the brothers, they could be developed by showing their vulnerability. Perhaps they have nightmares about their past misdeeds and Hermione helps them face these demons. This would make them more complex characters rather than just being the 'bad guys' from the original story.
Hermione's character can grow by learning from Alphard's past mistakes. Maybe Alphard made some decisions in his life that led to certain consequences for the Black family. Hermione, seeing these, could apply the lessons to her own life and her relationships within the wizarding world. As for Alphard, his character could be developed by having him interact with Hermione in a way that changes his view of the modern wizarding world. He could start to see the potential for change and growth that Hermione represents, and this could transform his character from a static figure of the past into a more dynamic part of the fanfiction story.
Their parents could be main characters. Blaise's mother, who might be a proud Slytherin - influenced witch, and Hermione's parents, who are Muggles but have a unique connection to the wizarding world through Hermione. Their interactions could add a lot of depth to the story.
