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.
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.
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.
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.
Well, it might make things a bit awkward at first. The Weasleys have always been close to Hermione, but if she's suddenly related to Draco, they might be a bit suspicious. They could worry that she has some of the Malfoy's not - so - nice traits. But over time, if Hermione shows that she's still the same person, they'll probably accept it.
Well, in such a fanfic, it might show how Draco and Hermione's relationship evolves over time. It could start with them being at odds due to their different houses and family backgrounds. But as the story progresses, they might find common ground. For example, they could both be interested in a particular area of magic that forces them to work together, and through that, their feelings start to change.
Draco and Hermione are often popular characters in fanfiction. Draco is usually depicted as a Slytherin student with a complex personality, and Hermione is known for her intelligence and determination.
A possible plotline might be that a dark wizard is after Hermione because of her new - discovered connection to the Malfoys. Draco, feeling a sense of family loyalty despite their differences, decides to protect her. Along the way, they learn more about their family's past and the reasons behind Hermione being separated from them. It could also involve Hermione trying to reconcile her Gryffindor values with the Slytherin - like values of the Malfoy family. There might be a scene where they have to face their parents together, and the Malfoy parents have to accept Hermione as their daughter, which would be a huge shift in their pure - blood ideology.
Hermione's character would likely experience a great deal of internal conflict. On one hand, she has her Gryffindor values and her loyalty to her friends like Harry and Ron. But on the other hand, she now has this new family connection to the Malfoys. She might become more empathetic towards Draco and start to understand the pressures he has faced as a Malfoy. Her confidence might be shaken a bit as she has to re - evaluate who she is in the context of this new family. She may also become more secretive as she tries to figure out how to handle this new situation without losing her old friends.
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.
