Sometimes, the plotlines in fanfiction can be a bit outlandish. If Ron is constantly getting into trouble in a way that Hermione has to constantly clean up after him, it would be understandable for her to be fed up. This could be different from the more equal partnership they had in the original series.
Maybe in some fanfictions, Ron is portrayed in a way that doesn't match Hermione's idea of him. For example, he might be made overly clumsy or insensitive, which could annoy Hermione.
One possible reason could be that their different career paths put a strain on their relationship. Ron might be more focused on his Auror work, often away on dangerous missions, while Hermione is deeply involved in the Ministry's research and reform projects. The long hours and high - stress of their jobs could lead to less time for each other and growing apart.
Another reason could be that the fanfiction is full of clichés when it comes to their relationship. It always follows the same tired plotlines, and Hermione, being the intelligent and forward - thinking witch she is, is tired of seeing such unoriginal takes on their relationship.
One reason could be a divergence from the original character traits. In the original story, Hermione and Ron have a complex relationship with love and friendship. Fanfiction that misrepresents Hermione's feelings towards Ron might go against the essence of her character. Maybe the fanfiction portrays her as hating Ron in a way that doesn't fit with her growth and development in the official series.
It's possible that Harry hates it because he has a certain image of Ron and Hermione in his mind. Fanfiction can sometimes create versions of them that are completely different from what he knows. For example, some fanfiction might focus on a love triangle that he doesn't think exists in their real relationship. This divergence from his perception could lead to his dislike.
Power could be a reason. If there's a chance for Ron and Hermione to gain a great deal of power by turning against Harry, some fanfictions might explore this. For instance, a new dark power might offer them something they've always desired, like the ability to reform the wizarding world in their own image. They might think Harry would oppose this, so they betray him to get what they want.
One possible reason could be a misinterpretation of their relationships. Maybe the author wants to explore a different dynamic where Harry and Hermione bond over Ron's perceived flaws, like his occasional laziness or his insecurities that might come across as annoying to them in this fictional scenario.
Well, some writers might be interested in exploring the 'what if' scenarios that are not part of the original story. It could also be a way to express their own views on relationships that are different from what was presented in the 'Harry Potter' series. Additionally, it could be a means to add a sense of realism, as in real life, relationships can face such challenges, even if it's not what we expect for these beloved characters.
It could be due to Dumbledore's decisions regarding Harry. Sirius is very protective of Harry. If he thinks Dumbledore is using Harry in some way for the greater good without fully considering Harry's well - being, he would be fed up. For instance, Dumbledore's decisions about Harry's participation in the Triwizard Tournament could be a point of contention for Sirius.
Well, they could ask for Hermione's input! Just kidding. Seriously though, writers could break free from the traditional molds of how Hermione and Ron are portrayed in fanfiction. Explore different timelines or scenarios where their relationship isn't the main focus but still an important part of the story. Also, get rid of any misogynistic or one - dimensional portrayals of Hermione in the fanfics.
