It's interesting because it combines two very different characters. Hermione is known for her studiousness and loyalty to her friends, while Blaise has that Slytherin mystery. Merging them as siblings gives a whole new dynamic to explore.
One popular story might be 'The Zabini - Granger Bond'. It delves into how Blaise and Hermione, as siblings, navigate the wizarding world together. Their different personalities, with Blaise's Slytherin cunning and Hermione's Gryffindor bravery, create interesting interactions.
Hermione would still likely be her intelligent, book - loving self. However, having Blaise as a brother might make her a bit more cautious in her interactions with Slytherins. She might also have a bit more of an edge, as she would be exposed to the Slytherin way of thinking through Blaise. Blaise, on the other hand, might be a bit more open - minded. With Hermione as his sister, he could learn to respect the values of Gryffindor, like courage. He might also be more protective of Hermione, which could show a softer side of his personality that wasn't as evident in the original story.
Well, if Hermione and Blaise were siblings, Hermione might have had access to different knowledge and resources. Blaise comes from a different social circle in the wizarding world. This could have influenced Hermione's studies. Maybe she would have been exposed to some Slytherin - favored magic earlier. In terms of the overall plot, the conflict between the houses might have been less intense. Since Hermione has friends in Gryffindor and a brother in Slytherin, she could have played a greater role in promoting unity among the students. And Blaise himself might have changed. With Hermione as his sister, he might not be as cold towards the Gryffindors as he was in the original story.
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.
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.
They're popular because it's an interesting and unexpected pairing. Fans like to explore new relationships that deviate from the original canon. Hermione and Blaise come from different backgrounds in the HP world, so seeing them as twins creates a whole new dynamic to play with.
There are some out there. However, the quality can vary greatly. Some might focus on a romantic obsession where Blaise is constantly pining for Hermione, while others could take a more platonic but still intense interest approach. It really depends on what you're into in terms of story themes and writing styles.
Another theme is the exploration of the wizarding world from their combined perspectives. Fanfictions often use their relationship as a means to show different aspects of magic, Hogwarts, or the wizarding society that might not be as easily explored through other characters. For example, they might go on adventures in less - known parts of the wizarding world.
One possible fanfiction could be about Blaise, Hermione and Draco all studying in the library. Maybe they start off as rivals, but as they spend more time in the library together, they begin to understand each other better. For example, Hermione might be helping Blaise with a difficult spell, and Draco overhears and joins in with some of his own knowledge. This could lead to an unlikely friendship between the three of them.
