Hermione is Sirius's twin sister fanfiction: How could this change the storylines in the Harry Potter series?

Well, if Hermione were Sirius's daughter in fanfiction, it would change a lot. For one, Hermione might have had a very different upbringing. She could have grown up with more knowledge about the wizarding world's secrets from Sirius. And in the Hogwarts years, her relationship with Harry and Ron might have been more complex. Maybe she would have been more involved in the Order of the Phoenix affairs earlier. Also, her magical abilities might have been influenced in different ways, as Sirius was from an old and powerful wizarding family.

It would completely transform the story. Hermione being Lily's twin would mean that the Marauders might have interacted with Hermione as well. Sirius and Remus might have seen her as an additional person to protect. And Hermione's presence could have potentially led to different outcomes in the events leading up to James and Lily's death. She might have been able to come up with a different plan to hide from Voldemort, using her vast knowledge of magic.

Well, if Hermione had a twin sister in fanfiction, it could change the story in many ways. For example, there could be more help for Harry and Ron. The twin sister might have different skills or knowledge that could assist them in their adventures. Maybe she's better at potions or has a special connection with certain magical creatures. It would also add more family drama and relationships to explore. Hermione's relationship with her sister could be a mix of love, rivalry, or both. This new character could also interact differently with the other students at Hogwarts, like having her own group of friends or enemies.

Well, if Hermione was James' twin sister in a fanfiction, it would completely change the dynamics. For one, Hermione's intelligence and magical ability would be part of the Potter family from the start. The Marauders might have had an even more powerful member in their group. And Hermione could have influenced James' actions towards Snape in a different way, perhaps lessening the animosity between them. It could also mean that Hermione would have a different backstory, growing up in the Potter household instead of with Muggles.

Well, if Hermione was Draco's little sister in fanfiction, it would completely turn the story on its head. For one, the Gryffindor - Slytherin dynamic would be super messed up. Hermione, being a know - it - all Gryffindor, and Draco, the snobbish Slytherin, their relationship would be full of internal conflict. Instead of being enemies, they'd have a family connection. This could lead to some really interesting scenarios where Hermione might be torn between her Gryffindor friends and her Slytherin family. Also, Draco might have to protect Hermione from the more evil Slytherins like Bellatrix, which would be a strange role - reversal. And it could change the way the whole wizarding world views blood purity because Hermione, as a Muggle - born, being related to a pure - blood Malfoy would shatter some long - held beliefs.

Well, if Hermione was Lily's sister in fanfiction, it could mean that Hermione might have had a closer connection to Snape. Since Snape was in love with Lily, he might have treated Hermione differently. Also, Hermione could have had some of Lily's magical abilities passed down genetically, which could have made her even more powerful. And it might have influenced the way Voldemort saw Hermione, as he had a special interest in Lily.

Well, if Hermione was Tonks' sister in fanfiction, it could lead to some really interesting changes. For example, Hermione might be more involved in the Order of the Phoenix from an earlier stage. Since Tonks was part of it, Hermione could have insider knowledge and be more directly involved in the fight against Voldemort. Also, it could change her relationship with Harry and Ron. Maybe she'd be more secretive about some things because of her connection to Tonks and the Order.

Well, it could change a great deal. For one, Hermione might have more access to inside knowledge about Hogwarts. McGonagall could be more protective of her, which might lead to different situations where Hermione is involved. For example, in dangerous situations, McGonagall might be more likely to step in directly to protect Hermione, rather than just as a teacher protecting a student.

She could have a very different relationship with Harry. Instead of being just friends, she might be more like an older sister figure, using her family knowledge to guide him. With Ron, their relationship could be more complex. Maybe there would be some jealousy from Ron as Hermione would have a more prestigious family background. And with the other members of the Black family, she would have a family bond. Some of the Black family members who were against Voldemort could be her allies in a more personal way.

If she exists, it might affect the relationship between Harry and his friends. For instance, Ron and Hermione might also become closer friends with her. And she could bring a new perspective to their group. Say she is more interested in the history of magic and spends time researching in the library, she might find clues that help them solve problems in a different way than Harry would have on his own.
