A possible storyline is them teaming up to solve a mystery related to their family. Maybe their parents were involved in something before they were born, and now Draco and Hermione have to follow the clues. In some fanfictions, they find that their family has a connection to an ancient magic. They start to learn about their family's past together, and along the way, they overcome their initial differences. Draco's Slytherin cunning and Hermione's Gryffindor bravery combine to make them a formidable duo when it comes to unravelling the secrets.
Hermione would likely become more understanding of Draco's situation. In the original stories, they were enemies. But as siblings, she would see the pressures he was under from his family. This could lead to her being more empathetic. Draco, on the other hand, would probably have to tone down his arrogance. With Hermione as his sister, he'd be constantly challenged. He might start to show more humility, like in one fanfiction where he apologized to Harry and Ron for his past behavior because Hermione made him realize how wrong he was.
One common plot twist is the revelation of a hidden family connection that makes them siblings. Another could be that they have to team up against a common enemy, like a dark wizard who is targeting their family. It might also be that Draco has to choose between his Slytherin friends and his new - found sister Hermione when there's a conflict between them.
Well, it's fairly popular. Fanfiction often takes canon characters and twists their relationships. In this case, having Hermione as Draco's sister means there would be a lot of family drama and conflict. It's a great concept for exploring different aspects of their personalities. For example, Hermione's intelligence and Draco's pride could clash or work together in unexpected ways in family situations.
At first, they're likely to be shocked. But then they start to understand each other more. Draco might become more protective of Hermione, and Hermione might see a different side of Draco. They go from being rivals to having a family - like bond.
There are some. However, the idea of them as siblings is a bit of a departure from the original series. But in fanfiction, creativity knows no bounds. Some stories might focus on how their shared traits, like their intelligence and courage, are enhanced by their newfound sibling connection. It could also lead to some heartwarming moments, like when they celebrate holidays together as a family for the first time.
In such a fanfic, their relationship might start off rocky. Since they come from different backgrounds in the original series, Hermione being a Muggle - born Gryffindor and Draco a pure - blood Slytherin. But as siblings, they could gradually find common ground. Maybe they start to protect each other from the prejudices of the wizarding world. For example, Draco might use his pure - blood status to shield Hermione from some of the nastier comments about her blood status, while Hermione could help Draco see the value in hard work and friendship rather than just pure - blood elitism.
Well, loyalty is a big one. Since they are siblings in these fanfictions, their loyalty to each other becomes even more pronounced. They will stand by each other no matter what. Another theme could be the exploration of their family heritage. Maybe they find out they are part of an ancient magical family. And of course, there's the theme of growing up together, facing the challenges of Hogwarts and the wizarding world as siblings.
One common theme is family secrets. Since Hermione and Draco are from different families in the original series, there must be some big secrets if they are siblings in fanfiction. Another theme is identity crisis. Hermione might struggle with her new identity as a Malfoy. And of course, there's the theme of redemption. Draco could be influenced by Hermione's good nature and change for the better.
It would be a huge shift. Hermione would probably have access to the Malfoy family secrets and resources. This could give the trio an edge in their adventures. Draco might also be more protective of Hermione, which would be an interesting twist. It could lead to some really complex family drama, especially considering the Malfoy family's standing in the wizarding world and Hermione's friendship with Harry, who is seen as an enemy by the Malfoys.
