They could come from a very wealthy pure - blood family. Since Blaise is often depicted as coming from a well - off pure - blood family in the original series, if Hermione was his sister, she would also be part of this. Their family might be one of those that have a long history in the wizarding world, with a large manor and a collection of rare magical artifacts. But they could also be a family that values both intelligence (like Hermione) and the Slytherin traits that Blaise has, such as ambition and cunning. There might be a lot of family pressure to succeed in different ways, with Hermione being pushed towards academic success and Blaise towards more political or social success within the wizarding community.
Perhaps their family has a history of being involved in both the light and dark sides of magic. This would create an interesting backstory. Hermione's inclination towards the good side could be a result of her own personal beliefs, while Blaise might be more on the fence or even slightly leaning towards the darker aspects of magic due to family influence. Their family could be a bit of an enigma, with some members being well - respected in the wizarding society for their contributions, while others having a more shadowy reputation. They might live in a large, old - fashioned house filled with secrets and hidden rooms, where family members are constantly jockeying for power and influence within the family structure.
It's possible that their family was persecuted during the reign of Voldemort. This could have made them more determined to fight against the dark side. Their family could also have some kind of hidden magic or artifact that has been passed down through the generations. This object could play a crucial role in the fanfiction, either as a source of power or as a key to unlocking some family secrets.
Their parents could be main characters. Blaise's mother, who might be a proud Slytherin - influenced witch, and Hermione's parents, who are Muggles but have a unique connection to the wizarding world through Hermione. Their interactions could add a lot of depth to the story.
Well, if Hermione were Blaise's sister in fanfiction, it would really shake up the Hogwarts dynamic. For one, the Gryffindor - Slytherin relationship would be more complex. Hermione is known for her strong Gryffindor values, and Blaise is a typical Slytherin. Their family connection might force students from both houses to interact more. In the original story, there was a lot of rivalry between the two houses. But with this new family bond, there could be more cooperation. Maybe they would start working together on projects or even defending each other against common enemies. It would also change Hermione's social circle. She would be more involved with the Slytherins, which could lead to some interesting character developments for both her and the Slytherin students she interacts with.
Well, it might involve a big family gathering where Blaise and Hermione's families meet for some special occasion. There could be some unexpected alliances formed. Their families might discover that they have more in common than they thought, like a shared interest in a particular branch of magic. And Blaise and Hermione might find themselves slowly warming up to each other in this family - centered environment.
One new storyline could be Hermione having to deal with the expectations of her Slytherin family while still being friends with Gryffindors. Another could be her using her Slytherin connections to solve mysteries at Hogwarts in a different way. Maybe she teams up with some Slytherin students to uncover secrets that the Gryffindors wouldn't have access to on their own.
If Hermione were Blaise's little sister in fanfiction, it would completely change the social dynamics at Hogwarts. The Gryffindor - Slytherin rivalry might be more complex. Hermione's studious nature could be seen as a Slytherin trait in this context. And Blaise might be more protective of her, which could lead to some interesting interactions between the houses.
Their family background could be really diverse. Maybe they have a family full of strong - willed witches. Their parents could be part of an old wizarding family that has been somewhat on the outskirts of the mainstream magical society. This would explain Hermione's thirst for knowledge as she tries to bring her family more into the limelight in the magical world, while Tonks' more rebellious nature could also stem from this family position.
One great Hermione is Blaise's mate fanfiction is 'The Unlikely Bond'. It beautifully weaves their relationship as they start off as rivals but gradually find a deep connection. The author does an excellent job of portraying Hermione's intelligence and Blaise's cool exterior with a warm heart beneath. Another one is 'Blaise and Hermione: A Different Path' which takes a more unique approach to their relationship, set in an alternate universe where Hogwarts has different rules and social dynamics. It's really interesting to see how they navigate their feelings in such a different setting.
One possible fanfiction could involve Hermione and Blaise coming from different backgrounds in the wizarding world. Their relationship might start as an unexpected encounter. Maybe they are paired together for a special project at Hogwarts. As the story progresses, Hermione discovers she's pregnant. This could lead to a lot of drama as they face the reactions of their friends and families, who might be against their union due to the house rivalries. For example, Hermione's Gryffindor friends could initially be skeptical of her relationship with Slytherin Blaise.
One adventure could be that they go on a journey to find a rare magical ingredient for a potion. It's located in a dangerous forest. Hermione's knowledge of magical plants and Blaise's skills in self - defense (learnt from his Slytherin upbringing) help them navigate through the forest. Along the way, they encounter strange magical beasts and have to use their combined wits to overcome the obstacles. They also have to deal with other wizards who are also after the ingredient, leading to some tense confrontations.
