Well, in the original series, Draco was often an antagonist to Harry and Hermione. But in fanfiction where they are a pack, they become allies. Harry and Hermione, who were already friends, now have to accept Draco into their inner circle. They start to see Draco's redeeming qualities. Draco, on the other hand, has to let go of his pure - blood supremacist views and learn to respect Harry and Hermione for who they are.
In the original series, their relationship was mainly defined by the house divide and their different loyalties. However, as demigods, a whole new dimension is added. They would have to put aside their old grudges because they are now part of a different world with different rules. Their relationship could become a friendship built on mutual survival and the understanding of their demigod natures. They may even find that their differences as a Slytherin and a Gryffindor are assets when dealing with the various tasks and threats that come with being demigods. Their bond could grow as they explore their new powers and face challenges that only they, as demigods, can understand.
The relationship between Harry and Draco would change drastically. Instead of being rivals, they would have to come to terms with being brothers. There would be a lot of initial tension as Draco's Slytherin upbringing clashes with Harry's Gryffindor values, but eventually they might learn from each other. Hermione, being part of the triplets, would act as a mediator between them.
In the original series, their friendship was built on a foundation of trust and common goals, like fighting Voldemort. In a married fanfic, that trust would be even deeper. They would be more involved in each other's daily lives. For instance, Hermione might be more involved in Harry's Auror work, giving him advice on how to handle certain magical cases. And Harry would be more involved in Hermione's efforts in the Ministry of Magic for the betterment of the wizarding world. Their relationship would be a blend of love, friendship, and partnership, which is different from just the friendship they had before.
In the original books, Draco and Hermione were mostly enemies. But in these fanfictions, with Draco as Hermione's master, there's a power imbalance that changes things. Draco has a certain authority over Hermione which makes their interactions more tense and charged.
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.
One interesting plotline could be them working together to solve a mystery within Hogwarts that the regular faculty can't handle. They combine their unique skills - Harry's courage and leadership, Hermione's intelligence and Draco's knowledge of the Slytherin side of things. For example, they might be on a quest to find a hidden magical artifact that has been causing strange occurrences in the school. This forces them to put aside their differences and really function as a pack.
The original dynamic was very much based on the pure - blood vs. Muggle - born divide. In fanfiction, this can be broken down. Writers might have Hermione and Draco meet in a different context, outside of Hogwarts perhaps. This new setting allows them to form a relationship without the pre - existing biases. It gives a chance for a fresh start, where their personalities can interact without the weight of the wizarding world's social structure getting in the way right from the start.
It completely changes the relationship dynamics. In the original story, Draco and Hermione are more like rivals. But in fanfiction where he cheats on her, it creates a whole new layer of animosity and heartbreak. Hermione, who is usually strong - willed, has to deal with the betrayal in a different way than she does with her academic or magical challenges in the original.
Over time, if the fanfiction progresses, Hermione could become a sort of bridge between Ron and Draco. She might encourage them to get along, now that Draco has shown that he can be on Hermione's side. Draco might also start to see Ron in a different way, realizing that Ron's jealousy or rudeness towards Hermione was born out of his own insecurities. This could potentially lead to a more complex and interesting dynamic between the three of them.
Their relationships could be developed uniquely by having them participate in a magical tournament that's not like the Triwizard Tournament. They are on different teams but have to cooperate secretly to overcome some corrupt judges. Draco might start to see Harry and Hermione in a new light as they work together to expose the wrongdoings. This shared experience outside of the normal Hogwarts rivalries can bring them closer.
