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.
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.
In these fanfictions, Draco's arrogance usually takes a backseat. The betrothal forces him to interact with Hermione on a deeper level, and he realizes that there's more to her than just being a 'Mudblood' in his old view. His personality becomes more complex as he tries to balance his Slytherin pride with his new - found feelings for Hermione. Hermione, on the other hand, might become a bit more secretive. She has to deal with her new relationship with Draco while also maintaining her friendships, and she may not be as open with her friends about her true feelings for Draco at first.
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's personality might change in that she would have to be more diplomatic. Instead of always speaking her mind bluntly as she usually does, she'd need to consider Draco's feelings and the situation of their arranged marriage. She could become more patient too. For Draco, he might become more self - reflective. Being married to Hermione, who is so different from him, would force him to look at his own prejudices. He could develop a more humble side as he realizes that Hermione has a lot to offer despite being a Muggle - born.
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.
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.
Bankotsu's personality could develop in terms of his sense of responsibility. With the reader being pregnant, he realizes he has more than just his own life and goals to think about. He might become more serious and less reckless in his actions. The reader's personality might grow in confidence as she navigates the changes in her body and the new life she's bringing into the world. She could start to stand up for herself and her unborn child more, even against Bankotsu if she feels he's being too overbearing. This would create an interesting dynamic between them as they both adapt to the new situation.
Hermione's strong - willed and intelligent personality means she'll be a driving force in their family. She'll likely ensure their children are well - educated in both magic and Muggle knowledge. Draco, with his pride and sense of family honor, will be protective. However, their different personalities could also lead to clashes. For example, Hermione's eagerness to embrace new ideas might conflict with Draco's more traditional pure - blood views at times. But they can also balance each other out. Hermione can soften Draco's more rigid edges, and Draco can give Hermione a better understanding of the wizarding world's old - fashioned ways, which ultimately benefits their family life.
Draco can be developed by showing his vulnerability during the naked crawl. His pride is usually a big part of his character, so this situation would force him to face his insecurities. For example, he might be worried about what others think of his physical appearance. Also, his resourcefulness can come into play as he tries to find a way to end the situation or at least cover himself up.
