One reason could be love. Hermione is a smart and kind - hearted girl, and the Weasley boys might all develop feelings for her. Jealousy would then be a big factor in their fights.
Another possibility is that they see different qualities in Hermione that they each value. For example, one might admire her intelligence for academic purposes, another might be attracted to her courage. And they fight over who gets to be closer to her to benefit from those qualities in different ways.
Maybe it's about status. In the wizarding world, Hermione is a very talented witch. If one of the Weasley boys gets closer to her, it could seem like he's getting an advantage in terms of social standing or magical influence, so the others might fight over her to prevent that.
One possible reason could be jealousy. Maybe one of the Weasleys develops romantic feelings for Hermione and the others don't approve or also have feelings for her. Another reason might be related to her magical abilities. If Hermione has some unique magic or knowledge that the Weasleys think can benefit them or their family in different ways, they could fight over it. For example, her knowledge of ancient spells could be seen as a great asset.
Well, it could be Ron. He can be a bit hot - headed sometimes and might be the first to get jealous and start something. But it really depends on how the author of the fanfiction has written it.
In fanfiction, Sirius and Remus could fight over Hermione because of their different relationships with Harry. Since Hermione is Harry's close friend, Sirius might think that he should have more influence over Hermione to help Harry better, as he is Harry's godfather. On the other hand, Remus, being Harry's former teacher and friend, also feels a sense of responsibility towards Hermione because of her connection to Harry. This clash of responsibilities and their own personal feelings for Hermione can spark a fight.
One reason could be jealousy. Maybe Ron feels that Harry is getting too close to Hermione and he's afraid of losing her attention. In fanfiction, authors often play with the characters' emotions. Harry, on the other hand, might see Ron as being too possessive of Hermione.
One reason could be that they might have different interpretations of Harry's character in the fanfiction. Hermione, being logical, may see Harry in a more practical light, while Ron, with his emotional side, could have a different view.
Well, Hermione has a unique charm. In fanfiction, Bill could be attracted to her because of her strong sense of justice. She is always fighting for what's right, and Bill, who has seen a lot in the wizarding world, might admire that. Also, her loyalty to her friends is something that could draw Bill to her. He might see in her a kindred spirit in terms of being there for those he cares about.
It could be that Ron has his own insecurities. He might feel inferior to Hermione in terms of intelligence and magical abilities. By trying to control her, he hopes to feel more powerful or important. For example, if Hermione is always getting top grades and solving complex magical problems, Ron might think that by controlling her actions, he can somehow boost his own self - esteem.
Perhaps they have different ideas about the plot direction. Hermione, being the studious type, may want the fanfiction to follow a more logical and complex plot with Harry involved in solving mysteries or learning new magic. Ginny, on the other hand, might be more interested in a plot that showcases Harry's relationships, especially his relationship with her. So, this clash of interests could lead to a fight.
Well, it could be that in the fanfiction world, Ginny is portrayed as this super desirable character. Harry has a long - standing connection to Ginny, having known her since she was a little girl. But Dean is also attracted to Ginny's independent and feisty nature. So, they end up fighting over her. Maybe there are some misunderstandings too. For example, Dean might think Harry is just being overprotective when in fact Harry has romantic feelings for Ginny, and this leads to a fight.
One reason could be jealousy. Maybe Tony has been spending more time with one of them, and the other feels left out and jealous. For example, if Tony has been helping Steve with some high - tech projects and Bucky feels ignored, it could lead to a fight. Another reason might be a misunderstanding. They could misinterpret Tony's actions towards each of them. Say, Tony gives Steve a special gift, and Bucky thinks it means something more than just friendship, leading to a fight.
