For Hermione, her marriage to Harry might lead her to explore new areas of magic that she previously overlooked. Her personality could expand to include more risk - taking in the name of protecting their family. Harry's personality would likely be influenced by Hermione's logical thinking. He might become more methodical in his approach to dealing with threats, rather than just relying on his instincts as he often did before. And they both could develop a more private side to their personalities, as they share a life together away from the prying eyes of the wizarding public.
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.
Elizabeth's confidence may grow even more as she becomes the mistress of Pemberley. She could start taking on more social responsibilities and use her intelligence to make positive changes in the community. Darcy, on the other hand, might become more open and less reserved as he is influenced by Elizabeth's warm and sociable nature. He may start to show his emotions more freely and be more involved in the daily lives of those around him.
For Nico, his past traumas and his connection to the underworld could be explored more deeply. He could be shown to gradually open up more about his feelings, especially to Jason. For example, he might share his experiences with loss and how it has shaped him. Jason, on the other hand, his sense of duty and leadership could be developed by putting him in situations where he has to make tough decisions. He could also show more vulnerability, like when he doubts his own abilities in the face of a very powerful enemy. This would make their characters more three - dimensional.
One way to develop their relationship further is by showing them having deep conversations about their future. They could discuss what they want to do after Hogwarts, how they can change the wizarding world for the better. Also, they might start to understand each other's insecurities more. Hermione could open up to Harry about her fear of not being good enough sometimes, and Harry could share his concerns about living up to his reputation. This emotional sharing would bring them closer.
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.
Joey could be developed by showing his more responsible side as a husband. He was always a bit of a free spirit, but now he has to think about Melissa and their shared life. Maybe he starts taking on more household chores or financial planning, which is new for him.
For Minerva, you could explore her more emotional side. In fanfiction, show her struggling with her feelings for Severus. Maybe she has always seen him as a difficult colleague, but then realizes there is more to him. For Severus, delve deeper into his loyalty. You can write about how his loyalty to Dumbledore and Hogwarts extends to his relationship with Minerva. For example, he would do anything to protect her when Hogwarts is in danger because she is an important part of what he is protecting.
For Kira, you can show his growth from a reluctant hero to a confident leader within the marriage. Maybe he becomes more assertive in his beliefs. For Lacus, her kind - hearted nature can be explored more deeply as she uses it to support Kira and their new family. She could also become more politically savvy.
In a fanfiction, Loki's personality could be developed through his relationship with Darcy. His arrogance could be tempered as he realizes Darcy doesn't fall for his usual tricks. He might start to be more honest and sincere. Darcy, on the other hand, could become more confident in her abilities. Her encounters with Loki, a powerful being from another realm, could make her realize she has more to offer than just being a sidekick. She could start to take charge in situations and use her intelligence in a more assertive way. This would change the dynamic between them and make their relationship more complex and interesting.
Sam could start to take on more responsibility in the relationship and in their future family. Maybe she decides to go back to school or get a better job. Freddie, on the other hand, could become more confident in his role as a husband and father - to - be. He might start to stand up for himself more against Sam's sometimes overbearing ways, but in a loving manner.
To develop their characters further, they could be placed in a cross - cultural investigation. Tony, with his more worldly experience in some ways, and Spencer with his encyclopedic knowledge. They would have to learn from each other and adapt. Tony could learn more about different cultures on a deeper level from Spencer's research, and Spencer could learn how to interact with people in different cultural settings from Tony's practical experience. This would add new layers to their personalities and their relationship.
