Hermione is Lily's sister fanfiction: How could this change the storylines in the Harry Potter universe?

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, it could change a great deal. For one, Hermione might have had access to more knowledge and magic earlier. Minerva could have secretly trained her, giving her an edge in her studies. This could also change her relationship with Harry and Ron. Maybe she would be more cautious about getting into dangerous situations as she wouldn't want to disappoint her mother.

It can change the dynamic between characters. For example, Hermione with Lily's traits might be more nurturing towards Harry, which could change the way their friendship works. She could also influence Ron in a different way, maybe being more of a guiding figure for him.

If Hermione were Sirius's twin sister in fanfiction, it would mean a major shift in her character arc. Firstly, her appearance might be different as she would likely inherit some Black family traits. Her magical abilities could also be influenced. In the original story, Hermione was always an over - achiever, but with the Black family connection, she might have had a different approach to magic. Maybe she would be more confident in her natural abilities rather than relying so much on study. In the fight against Voldemort, she could have used her family's resources and connections. For example, she might have known about secret Black family spells or artifacts that could have been useful. Her relationship with Snape would also be very different. Since Snape had a history with the Black family, he might have treated her with more respect or more animosity, depending on how the story was written.

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, it could make for some really interesting dynamics. For example, Oliver might be more protective of Hermione, and Hermione could have an easier time getting involved with Quidditch related things since her brother is so into it. It could also change how the Gryffindor team views Hermione, seeing her as more of an insider since she's related to their captain.

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.

In fanfiction, anything can be possible. Writers might create a scenario where time - traveling or some sort of magical alteration to the past occurred. Maybe a powerful spell was cast that changed the course of events so that Hermione could be born to James and Lily. However, it's a huge departure from the original story's timeline.

It would be a huge change. Since Hermione is known for her studious nature, she could have made James more academically inclined. Their family interactions would be different too. She might have been the voice of reason in the family, affecting James's decision - making. In the context of the wizarding war, she could have provided insider knowledge about the Death Eaters much earlier as she was well - read. This would have put James and his friends in a better position to fight against the dark forces.
