One key plot point could be Bellatrix's initial motives for taking Hermione under her wing. Maybe she sees potential in Hermione's magic and wants to corrupt it for her own dark purposes. Another aspect could be Hermione's struggle to maintain her own values while being in Bellatrix's influence. For example, she might resist Bellatrix's attempts to make her use dark magic. Also, the relationship between the two characters would be complex, with Bellatrix being a cruel and unpredictable mentor, and Hermione constantly trying to outwit her in some way.
Well, often there's the plot of Hermione being the one to see something in Bellatrix that others don't. So she might start a relationship with her that gradually turns into marriage. There could be a lot of conflict with the Order of the Phoenix who would be against Hermione's relationship with a former Death Eater. And Bellatrix might have to face her past actions and make amends in some way as part of the relationship development.
Hermione would probably develop a much harder exterior. Bellatrix is a cruel and unforgiving figure, and Hermione would need to be tough to survive in her presence. She might become more calculating in her actions, always thinking several steps ahead. Her knowledge of magic would also take a different turn. She'd be exposed to dark magic, which would either make her more determined to fight against it or, in a more complex scenario, make her see some aspects of it that she hadn't considered before. This could lead to internal moral dilemmas that shape her character in new ways.
Well, in many such fanfictions, a key plot point could be the two characters realizing they misjudged each other. For example, Draco might see Hermione's true strength and intelligence not as something to be hated but respected. Another common plot point is them working together on a task, perhaps something related to the wizarding world's safety. This forces them to interact and gradually amend their relationship. Also, there could be a moment where they defend each other against other characters' prejudices, which is a big step in amending their relationship.
Well, in many 'Hermione is a Lost Heir' fanfictions, a common plot point is the discovery of her new heritage. This could involve finding out she's related to an old and powerful wizarding family. Another key point might be how this new status affects her relationships at Hogwarts, like with Harry and Ron. It could create some jealousy or a feeling of her being different from them now.
In Hermione adopted by goblins fanfiction, a major plot point could be her education. The goblins might have a different approach to teaching magic compared to Hogwarts. Hermione would have to adapt to this new learning environment. There could also be a plot point about her identity. Is she still considered a witch? Or does she become something in - between a witch and a goblin in the eyes of the wizarding world? And her interactions with other magical creatures might change. Since she's associated with goblins now, some creatures might see her differently, which could create new alliances or rivalries.
In some fanfictions with this concept, one key plot point could be Hermione's struggle to resist Voldemort's control while secretly trying to undermine his plans. For example, she might use her intelligence to mislead the Death Eaters. Another point could be the internal conflict she faces between her loyalty to her friends and the need to survive in this dark situation. And sometimes, there could be a sub - plot about her trying to find a way to break the enslavement spell or curse that binds her to Voldemort.
One key element is the contrast between their personalities. Bellatrix is wild and often cruel, while Hermione is logical and kind. Their relationship in these fictions is about how they bridge this gap.
One possible plot could be that Bellatrix captures Hermione and tries to torture her for information about Harry. But Hermione, using her wits and some new-found powerful magic she has been secretly studying, manages to turn the tables and kill Bellatrix in self - defense.
In these fanfictions, a crucial plot point might be the discovery of a shared secret. Hermione could be researching something in the library, and Draco stumbles upon her. They find out that they are both interested in an ancient magic that is related to 'Fire and Ice'. This shared interest becomes the starting point of their relationship. As they delve deeper into this mystery, they face obstacles. Other students might be against their new - found alliance, or there could be a teacher who tries to stop them from exploring this dangerous magic. But through it all, their bond grows stronger as they try to uncover the secrets of the 'Fire and Ice' magic.
One key element is the power dynamics. Since Bellatrix is a very powerful and experienced dark witch, and Hermione is a young, intelligent witch, seeing how the power balance shifts during their encounter is exciting. For example, in some fanfics, Hermione uses her quick thinking to outwit Bellatrix's brute force.
