Hermione is Sam and Dean's sister fanfiction: How could this change the storylines of the original shows/movies?

If Hermione was their sister, it would change a great deal. The original storylines are quite distinct. In the Supernatural world, Dean and Sam are used to a certain way of life. But Hermione comes from a world of magic and wizards. Her presence as their sister would mean new dynamics. For example, she could use her knowledge of potions to create new substances to combat the supernatural. This would add a whole new layer to their adventures. It could also mean that the places they visit, like Hogwarts, could become part of their hunting grounds or places of refuge.

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.

One way it could work is by having Hermione's magical abilities blend with the hunting skills of Sam and Dean. For example, she could use spells to help them in their battles against supernatural beings. Maybe she could create protective charms around their hideouts or use her knowledge of potions to create antidotes for the various toxins they encounter. Also, her intelligence and quick - thinking would be an asset during their investigations, just like how she solves mysteries in the wizarding world.

Well, if Hermione were Bella's sister in fanfiction, it would completely mess up the magic systems of both universes. Hermione is from the wizarding world of Harry Potter with its own set of rules and magic, while Bella is in the Twilight universe with vampires and werewolves. Their personalities are also quite different. Hermione is intelligent and resourceful, while Bella is more... well, brooding and romantically focused. This new relationship could lead to some really strange crossovers, like Hermione trying to use magic to solve Bella's vampire - related problems or Bella introducing Hermione to the world of vampires, which would be a huge shift from the original storylines.

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, 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.

One interesting storyline could be the baby sister having special powers that she has to learn to control. Maybe she can communicate with spirits in a unique way, different from Sam and Dean, which adds a new dynamic to their hunting adventures.

If Hermione was Sam and Dean's sister in fanfiction, her interactions with Bobby would be great. Bobby is a wealth of knowledge in the Supernatural world, and Hermione with her own vast knowledge from the wizarding world could have some really deep conversations with him. She might also have a different relationship with the monsters they hunt. Instead of just killing them outright, she might try to find a more peaceful solution using her magic, which could lead to some tense interactions with Sam and Dean who are used to a more cut - throat approach.

She could be a nephilim, half - angel and half - human. This would put her in great danger as both angels and demons would be after her. Sam and Dean would have to constantly protect her and figure out a way to keep her powers in check.
