Well, in the fanfiction world, it could be that Bellatrix had a secret affair with a wizard who was related to Hermione's family tree. And through some magical interference or prophecy, Hermione ended up being born with Bellatrix as her mother. It might also involve a hidden magical pact that was made long ago and only comes to light in this fanfiction's plot.
One possibility could be through some dark magic or a complex time - travel plot. Maybe a spell was cast that altered Hermione's lineage in an alternate reality. For example, Bellatrix could have been forced into a situation where her magical essence was used to create Hermione in a very unorthodox way.
Fanfiction often plays with established characters in new and unexpected ways. Regarding Hermione being Bellatrix's sister, it could be part of a parallel universe concept. In this alternate reality, the rules of blood relations in the wizarding world are different. The author could be using this idea to show how different circumstances can shape a character. For example, Hermione might have some of Bellatrix's fierceness if they were sisters, or Bellatrix could have some of Hermione's intelligence, which would make for a very interesting story.
In fanfiction, anything can be possible. Maybe a time - travel or a powerful magic spell gone wrong could be used to create this strange relationship. For example, if there was a spell that messed with people's memories and lineages, it could make Hermione seem like Bellatrix's daughter.
There might be. Fanfiction writers often come up with wild and creative ideas. Having Bellatrix as Hermione's mother would completely change the dynamic of Hermione's character. It could lead to a much darker and more complex backstory for her, exploring how she deals with having such a dark - sided mother in a world where she's trying to be on the side of good.
In fanfiction, the idea of Hermione being Draco's mother can be made possible through alternate timelines or magical interventions. For example, a powerful spell could have altered their family relationships. It allows writers to explore different character dynamics and how it would change the story.
Well, in fanfiction, the author has the freedom to twist the original story. For McGonagall to be Hermione's mother, perhaps there was a powerful charm placed on Hermione as a baby to hide her true parentage. And McGonagall, being a powerful witch, had reasons to keep this a secret, like protecting Hermione from some dark forces that were after her because of her heritage.
Well, in fanfiction, the rules are often bent. Maybe it could be possible through some sort of magic or alternate universe scenario. For example, Loki might have used his shape - shifting abilities to take on a female form and through some complex plot device, end up as Peter's mother. It could also be part of a time - travel or multiverse - related plot where the normal rules of genetics and family relations don't apply in the traditional sense.
Another motive could be related to Bellatrix's loyalty to Voldemort. Maybe she suspects Hermione of something, and this is her way of getting a reaction out of her. She could be trying to unnerve Hermione to see if she gives away any secrets or shows signs of being involved in something that Bellatrix or Voldemort would be interested in.
In fanfiction, it might be possible if the author creates a whole new backstory. Say, Bellatrix was forced to give up her child (Harry) for some reason related to the power struggle in the wizarding world. Or perhaps there was a mix - up at the time of Harry's birth, and he was wrongly attributed to Lily and James. But these are all very far - fetched ideas that go against the original story.
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.
Well, it would completely change the story's dynamic. Hermione is a Gryffindor with a strong sense of right and wrong. Bellatrix is a Death Eater. If Bellatrix were her mom, Hermione might have a much more conflicted internal struggle. She could be torn between the values she's been taught at Hogwarts and the dark heritage she might inherit from Bellatrix.
