In a fanfiction, Hermione's intelligence can be developed by her constantly coming up with complex theories and solutions. For instance, when faced with a difficult magical riddle, she analyzes it from different angles. Sirius' wild side can be explored by having him break some minor Hogwarts rules just for the fun of it. Harry's determination can be shown as he refuses to give up on a quest, even when it seems hopeless. Draco's elitist attitude can be developed by him looking down on others not from pure - blood families. These different personalities can interact in various ways, like Hermione trying to rein in Sirius' recklessness, and Harry standing up to Draco's snobbishness.
Well, Draco's pride and his Slytherin upbringing make him initially very resistant to working with Harry and Hermione. He might be constantly trying to one - up them. Blaise, on the other hand, could be more of a mediator. He's also Slytherin but perhaps more open - minded. Hermione's intelligence and her Gryffindor courage mean she'll be the one pushing for solutions and not backing down from a challenge. Harry's sense of justice will drive him to do what's right even if it means working with his former enemies. In a story, their interactions could show how they grow from being at odds to understanding each other better.
For Hermione, her character can be developed by showing her vulnerability. Usually, she's so strong and in - control. But with Sirius, who has a more carefree and rebellious side, she could learn to let loose a bit. Maybe she starts to question some of the strict rules she's always followed. For Sirius, his character can be developed by becoming more responsible. He sees Hermione's determination and it makes him want to be a better role model for her.
For Hermione, her intelligence and determination can be further explored. She could use her vast knowledge of magic to take care of the 'baby' in the project. For instance, when the 'baby' gets sick, she quickly figures out a remedy. Draco, on the other hand, his pride and initially aloof nature can gradually change. Maybe at first he's reluctant to participate fully, but as he sees Hermione's dedication, he starts to let go of his pride and get more involved.
Hermione's strong sense of justice would play a big role. If there's any threat to the cub, she would fight tooth and nail to protect it. Draco's development could be a bit more complex. He might start as his typical haughty self, but as he witnesses Hermione's dedication to the cub, he could gradually soften. His relationship with his family and how it affects his view of the cub and Hermione can also be explored. For example, if his family has a negative view of Hermione's actions regarding the cub, he has to decide whether to side with them or with Hermione.
Hermione is studious and logical, while Draco is more prideful and used to a certain way of life. In the fanfiction, they could blend their personalities when they face a difficult magical problem. For example, Hermione's knowledge could be combined with Draco's resourcefulness (which he has, just in a different way than Hermione). Draco might know some secret family spells or have connections to get certain magical items, while Hermione figures out how to use them in the right way.
Hermione's already - strong - willed personality could become even more resolute as she takes on the role of Harry's wife. She might be more assertive in protecting Harry and their relationship. Harry, on the other hand, could grow in his confidence, especially with Hermione by his side constantly supporting him. Their marriage could also make them more empathetic towards each other's past traumas.
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.
Harry's usually shown as more open - minded in these fanfictions. His natural sense of justice and kindness is expanded to include Draco. Draco, on the other hand, is often made more complex. His pride is still there, but his softer side is revealed as he falls for Harry.
Their relationships could be developed uniquely by having them participate in a magical tournament that's not like the Triwizard Tournament. They are on different teams but have to cooperate secretly to overcome some corrupt judges. Draco might start to see Harry and Hermione in a new light as they work together to expose the wrongdoings. This shared experience outside of the normal Hogwarts rivalries can bring them closer.
Well, it should start with small interactions. Maybe they are paired for a Potions assignment. At first, they are both reluctant, but they gradually notice little things about each other. Draco might notice how Hermione is so focused and determined in her work, and Hermione might see Draco's precision in handling the ingredients. This initial mutual respect can be the starting point for a deeper relationship.
