The relationship would be very strained in some cases. The Blacks who adhered to the pure - blood ideology would be disgusted by Hermione's muggle - born heritage, despite her being Sirius' daughter. However, there could be some younger Blacks who would look up to her. Hermione's intelligence and courage could inspire them to break free from the old - fashioned and often cruel ways of the Black family. And Hermione herself would have to decide how much she wanted to be involved with the Black family and its affairs.
If Hermione was Sirius Black's daughter in fanfiction, her relationship with the Blacks would be full of contradictions. On one hand, the more traditional and dark - leaning Blacks would shun her for her beliefs and actions. On the other hand, she might be able to find allies among those Blacks who were trying to distance themselves from the family's dark reputation. She could be a unifying or a dividing figure within the family, depending on how she chose to interact with them.
Her relationship with Harry and Ron would be very interesting. At first, they might be shocked and a bit confused. But they'd soon realize that Hermione is still the same person they know and love. Harry might see her as an even stronger ally now, with her new - found divine powers. Ron, on the other hand, might be a bit jealous at first but then come around. And with the other Hogwarts students, she'd be like a bit of a mystery. Some would be in awe of her, while others might be a bit afraid.
Her relationship with the Hogwarts professors could be interesting. Some, like Dumbledore, might have known about her all along but kept it a secret for her protection. So, she could feel a sense of betrayal at first but then understand his reasons. As for Snape, he might be particularly harsh on her because of her Black heritage, but she could prove him wrong with her kindness and courage. Among the students, she could form a clique with those who are outcasts or misfits, and together they could face the challenges of Hogwarts life.
It would likely make their relationship more complex. Harry might feel a bit jealous at first because he had such a strong connection with Sirius. Ron, on the other hand, might be a bit confused. But overall, they would still be her friends. They might be more protective of her, especially if there are threats related to Sirius's past enemies. And Hermione would have to balance her new identity as Sirius's daughter with her long - standing friendships.
If Hermione was Lucius' daughter, her relationship with other Slytherins would be complex. Some Slytherins would likely welcome her as a pure - blood heir of the Malfoy family. However, she might also face some jealousy. Her intelligence could be seen as a threat to some of the more power - hungry Slytherins. And given that Hermione has a strong moral compass, she might not fit in completely with the more devious Slytherin crowd. She could be an outcast among them while still being part of the house.
Well, Hermione being James' twin sister would make her and Sirius have a tight - knit relationship. Sirius would be part of her family in a way. He'd be there for her during her Hogwarts years, and they could bond over their shared love for James. Sirius might also teach Hermione some of the more secretive and dangerous spells that the Marauders knew, and Hermione would keep Sirius in line with her logical thinking and rules - following nature, creating a balanced and loving relationship.
She might develop by interacting with different magical creatures. For example, if she befriends a hippogriff, she learns about loyalty and respect for other beings. This could shape her character to be more empathetic. Additionally, her relationships with her teachers would play a role. A strict teacher might push her to be more disciplined, while a kind one could encourage her creativity, both aspects contributing to her overall character growth.
She might have a very conflicted relationship with the werewolf community. On one hand, she could feel a sense of connection because of her father. But on the other hand, she has been brought up in the wizarding world which often discriminates against werewolves. She might try to change the way the werewolf community is treated, using her influence as a Hogwarts student. However, some werewolves might not accept her, seeing her as someone who has had the privilege of growing up in the wizarding world and not fully understanding their struggles.
She would probably be more rebellious. Sirius was always against the status quo at Hogwarts. So, Hermione as his daughter would likely question the rules more often. Instead of strictly following the school regulations like in the original story, she could be at the forefront of student protests or challenges to the faculty's authority. She would also have a more devil - may - care attitude towards her grades, focusing more on the knowledge itself rather than the academic recognition.
She might initially have a tense relationship with the Weasley family. Since Sirius was close to them and they are Gryffindors, they might be a bit wary of her. But as time goes on, she could prove herself to them. With Harry, she could be a bit of an enigma at first. Harry might be curious about her and they could form a friendship based on their shared connection to Sirius.
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.
