It might be part of a 'dark' or 'alternate universe' fanfiction. In these types of stories, characters can be made to act out of character. The writer could be using this as a way to show a Ron who has been influenced by dark magic or some other negative force, causing him to use such a derogatory term towards Hermione.
Perhaps it's a way to explore the theme of prejudice within the wizarding world more deeply. By having Ron, who is generally a good character, say this, it forces the reader to think about how even the best of people can be influenced by the deeply ingrained ideas of blood purity. It could also be a lead - in to a story about Hermione standing up against this kind of prejudice and changing Ron's views.
One possible reason could be to create drama. Fanfiction often takes the existing relationships and twists them for the sake of a more engaging story. Maybe the author wants to explore how Hermione would react to such a hurtful comment from Ron, and how it would impact their friendship or potential romantic relationship.
Yes, there might be some fanfictions out there that explore darker or more complex storylines where such a thing could happen. However, this goes against the positive growth of their relationship in the original 'Harry Potter' series. In the canon, Ron's use of that term was a regrettable moment of weakness, and most fanfictions tend to uphold the characters' better natures.
The implications would be quite serious. Firstly, it would shock the readers who are familiar with their relationship. Hermione would be deeply hurt, and Ron would be seen as a character who has lost his moral compass. It might also change the power dynamics in the story. Hermione could become more withdrawn or vengeful, and Ron would have to face the consequences of his actions, either through guilt or the backlash from other characters. This could also lead to a divergence in the overall plot, with the focus shifting to their damaged relationship and how they might or might not overcome it.
Well, in the wizarding world, 'mudblood' is a very offensive term. If Lavender calls Hermione that in the fanfiction, it could lead to a serious rift between them. Hermione is a strong - willed character and she would likely be deeply hurt and angry. It might also cause a stir among their friends and classmates. Some might side with Hermione, feeling that Lavender's behavior is unacceptable, while others might be more neutral or try to play peacemaker.
Some fanfictions might have Hermione immediately cut Ron out of her life. She's a strong - willed character, and such a hurtful comment could be the last straw. This would then lead to a story about her moving on without him and finding new friends or allies.
One possible reason could be jealousy. Maybe Ginny is jealous of Hermione's intelligence or her close relationship with Harry. So, out of spite, she uses the slur.
One possible reason could be that he's been influenced by some dark magic or a spell that makes him act out of character. Another reason might be extreme jealousy, say if Hermione is getting more recognition in the wizarding world than him for some time and he lashes out in a moment of weakness.
One key theme is acceptance. Ron has to fully accept Hermione's'mudblood' status, and in turn, she has to accept that he may not always understand the full extent of the discrimination she faces at first. It's about growing together in understanding.
One reason could be that Hermione is a strong - willed character. In fanfiction, Ron might be depicted in a way that undermines her independence. She wants to be seen as her own person, not just as Ron's love interest.
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.
In the Harry Potter universe, 'mudblood' is a derogatory term for wizards or witches with non - magical parents. In fanfiction, 'hermione is not a mudblood' likely means that the story will not tolerate or include any plotlines where Hermione is treated as less because of her 'mudblood' status. It could be a way to rewrite or correct the often unfair and discriminatory situations she faces in the original series regarding this.
