Another plotline could be Hermione exploring her dark magic heritage. She might be tempted to learn some of the spells that Bellatrix was known for, but then struggle with the moral implications. This internal conflict could be a major part of the story, as she tries to balance her Gryffindor values with her new - found connection to a dark past.
One possible plotline could be Hermione's discovery of her true parentage. Maybe she finds a hidden letter or a magic - bound memory that reveals the truth. This would send her into a state of shock and confusion as she tries to reconcile her own values with the fact that her mother is Bellatrix, a known Death Eater.
She would likely have a more conflicted personality. Hermione is known for her strong moral compass, but if she were Bellatrix's daughter, she might struggle more with her darker instincts. For instance, she might be more tempted by the Dark Arts.
A possible plotline could be that Hermione discovers a hidden family connection between them that explains the soulmate bond. For example, there could be some long - lost relative who was involved in a powerful magic that now links their souls.
Perhaps she discovers a hidden power within herself that neither of her parents had. This power could put her in a unique position in the wizarding world. She might have to decide whether to use it for good or be influenced by her mother's dark side. For example, if she has a special gift for mind - reading, she could use it to help people or manipulate them like Bellatrix would.
If Hermione was Bellatrix's daughter in the fanfic, her relationship with Draco would be a strange mix. Draco would probably be both intrigued and cautious. On one hand, he might think Hermione could be an ally due to her family connection. But on the other hand, he knows Hermione has always been on the side of the good guys. This could lead to a lot of tension and mind games between them as they try to figure out each other's true motives.
One possible plotline could be that Bellatrix, under some strange circumstances, is forced to teach Hermione magic in a very unorthodox way. Since Bellatrix is a Death Eater, she might initially try to corrupt Hermione with dark magic, but Hermione's strong will resists. Another could be that Bellatrix has some unique knowledge of an ancient magic that Hermione needs to learn for a greater good, like saving Hogwarts. They would have a very tense relationship filled with power struggles as Hermione tries to gain knowledge while Bellatrix tries to assert her dominance.
One possible theme could be transformation. For example, the horse might symbolize a transformation in Hermione or Bellatrix's journey. Maybe it represents a new power or a change in their relationship.
Well, a plotline could involve Hermione having hidden powers that are related to her being Voldemort's daughter. Maybe she has an ability to control dark magic in a way that no one else can. She could also be hunted by both the good and the bad sides. The good side might fear that she will turn evil like her father, and the bad side might see her as a threat to their power. Additionally, there could be a plotline where Hermione tries to redeem Voldemort through her connection to him, believing that there is some good in him after all.
Bellatrix was extremely cruel and devoted to the Dark Lord. Her daughter could be the opposite. Maybe she has a kind heart and is repulsed by the dark magic her mother practiced. She could be more empathetic towards others, especially those who were victims of the Death Eaters.
If Hermione were Bellatrix's daughter in the fanfic, it would make for a very interesting plot twist. Hermione might struggle with her identity, being raised in the wizarding world as a 'good' witch but having such an evil mother. It could lead to her being ostracized by the wizarding community. Also, her skills in magic could be different. She might have an innate understanding of the Dark Arts that she has to constantly fight against.
