Hermione could also use her magic skills to her advantage. She is a powerful witch, and in the Malfoy household, she may use her magic to create a space for herself where she can be true to herself. She might also use magic to subtly influence Lucius and make him more accepting of her and her beliefs.
One interesting plotline could be the clash of their different ideologies. Hermione, with her strong beliefs in equality and justice, and Lucius, from a traditional pure - blood family with elitist views. Their marriage, forced by the law, might lead to a power struggle within the Malfoy household as Hermione tries to assert her values.
For Hermione, it's about her growing in a new and often hostile environment. She has to deal with the pure - blood elitism which she has always opposed. This forces her to become more diplomatic while still holding onto her values. Lucius, on the other hand, has to re - evaluate his beliefs about muggle - borns. His character develops as he sees Hermione's intelligence and strength, which makes him question his former bigotry.
Their relationship could develop in a rather complex way. Given their very different backgrounds, there would be a lot of clashes. However, the marriage law forces them to coexist. As time passes, they might find common ground in their love for the wizarding world, albeit from different perspectives. Hermione could introduce Lucius to the idea of a more inclusive wizarding society, and Lucius could teach Hermione about the long - standing pure - blood traditions that have some value, if reformed. This mutual exchange could lead to a grudging respect and eventually something more like friendship or even love.
One possible plot twist could be that the marriage law is part of a political ploy. Maybe the wizarding government wants to unite the pure - blood and Muggle - born factions through this law. Hermione, being the strong - willed character she is, initially resists but then realizes she can use this situation to advocate for better Muggle - born rights within the pure - blood society. Lucius, on the other hand, has his own motives, perhaps trying to regain some of his lost status in the wizarding world by being seen as more 'open - minded' through this marriage.
Well, sometimes in these fanfictions, a common plot is that Hermione and Lucius are forced into the marriage by the law at first. But as time goes on, they start to discover unexpected similarities in their love for knowledge. For example, Hermione's thirst for magic knowledge and Lucius' in - depth understanding of the dark arts (not in an evil way but in a historical and academic sense). They might then team up to solve some magical mystery together, which not only brings them closer but also changes their relationship dynamic completely.
Well, perhaps he uses his influence in the wizarding world. Maybe he has some connections or knowledge that allows him to intervene and get Hermione out of the abusive situation. For example, he could use his status among the pure - blood families to put pressure on the abusers.
For Lucius, his development could be a slow process. At first, he resents being around Hermione, but as he witnesses her magic and her kind heart, he starts to question his own values. He may begin to see the error of his ways regarding blood purity. Hermione might develop more patience. Dealing with Lucius, who has such different views, makes her learn to tolerate and try to change someone rather than just oppose them.
Lucius has a sense of entitlement that comes from his pure - blood upbringing and family wealth. Hermione, being a Muggle - born (in the original story), has had to fight for her place in the wizarding world. So in fanfiction as siblings, Lucius might initially look down on Hermione's more inclusive views, while Hermione would be appalled by Lucius's prejudice. However, as the story progresses, they could learn from each other. Lucius could become more open - minded and Hermione could understand the pressures of a pure - blood family.
Well, it could be that Lucius uses his powerful influence in the wizarding world. Maybe he intimidates Ron with threats related to his family's status or he uses some dark magic to create a distraction and whisk Hermione away.
Well, in some fanfictions, Lucius might use his charm and power. He could be depicted as very persuasive and use his status in the wizarding world to make Hermione see him in a different light. Maybe he offers her opportunities for knowledge or power that she doesn't get with Draco.
