For example, they might both have an uncanny ability to solve complex magical puzzles, which could be a hint to their true relationship.
It could be a result of a time - travel or alternate reality plot. In an alternate universe, the rules of family relations are different. Hermione and Fleur could be sisters in this version of the wizarding world. Their relationship might develop as they both struggle to understand this new reality and how it affects their identities and their place in the wizarding community. They could find that they have to rely on each other to navigate this strange new world they find themselves in.
Perhaps Hermione discovers she has some long - lost connection to Aragorn's family. In the fanfiction, she could bring her knowledge of magic to Middle - earth. For example, she could use her healing spells to tend to Aragorn's wounded soldiers, and as they work together more closely, they come to recognize each other as family.
Well, they could start off with some initial misunderstandings. Maybe Hermione, being as intelligent as she is, could initially be suspicious of Jasper's motives. But as the story progresses, they could discover they have common interests, like a love for ancient magic or a desire to protect their world from a new threat.
They might have a very competitive relationship. Since both are strong - willed and talented. They could compete in things like magical duels or academic achievements. However, this competition could also strengthen their bond as they push each other to be better. And in times of danger, they would put aside their differences and protect each other like true sisters.
Well, they could start off not getting along. Tony, being used to his high - tech world, might not understand Hermione's magic at first. But then, when they face a common enemy, like a villain who is both a threat to the wizarding world and the normal world. They realize they need each other's skills. Hermione's ability to think on her feet in magical situations and Tony's quick - witted engineering could make them a great team.
It could be developed by having Fleur first struggle with her feelings internally. She might be confused because it's not a common type of attraction in the wizarding world. For example, she could write in a diary about her feelings for Hermione.
Often, in fanfictions, the development of their relationship is a slow - burn process. It could begin with simple exchanges of knowledge. Hermione might teach Fleur some complex magic theories, while Fleur could show Hermione some unique Beauxbatons magic. As they get to know each other better, they might start to have deeper emotional connections. Small gestures like helping each other in times of need or sharing secrets could lead to a more intimate relationship.
Well, it could be developed through some magical family secrets. Maybe there was a long - lost connection in their family tree that was only discovered in the fanfiction world. For example, a hidden adoption or a spell that had some unforeseen consequences on family relations.
Often, Dark Hermione's character is developed by showing her descent into the dark side. Maybe she starts to question the limitations of the 'good' magic she has been taught and becomes frustrated. For Dark Fleur, it could be through her desire for more power and recognition. Her beauty and confidence could be turned into tools for her dark pursuits.
A possible fanfiction plot could involve Hermione and Fleur working together to solve a mystery in the wizarding world. Maybe there is a series of strange magical occurrences that are baffling the wizarding community. Hermione's logical thinking and Fleur's intuition could combine to crack the case. Along the way, they learn about each other's strengths and weaknesses, and their relationship blossoms into a true partnership where they rely on each other and value each other's contributions.
In the fanfiction, Fleur could use her Veela charm in a positive way to create a sense of mystery and allure for Hermione. But instead of it being a controlling charm, it could be something that just makes Hermione curious about Fleur. Fleur could then take Hermione on adventures, like exploring hidden magical places. As they have these experiences together, their relationship would grow. Fleur could also be vulnerable with Hermione, sharing her insecurities, which would make Hermione see her as more than just a beautiful Veela but as a real person she can connect with.
