I recall one fanfiction where the 'Mudblood' concept was explored in a very different way. Hermione was trying to find a way to remove the stigma associated with it. Ron was by her side throughout this journey. And Harry's scar was somehow a key to unlocking an old magic that could potentially change the wizarding world's view on blood purity. It was a really interesting take on the characters and these concepts, and it showed how strong Ron and Hermione's relationship could be in the face of such complex issues.
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.
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.
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 Hermione could become more withdrawn or vengeful, and Ron would have to face the consequences of his actions, either through guilt or the backlash from other characters.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.
I'm not a big fan of such dark fanfictions, but you could try looking on fanfiction.net. They have a large collection of Harry Potter fanfictions, and you might be able to find one with that plot there.
One popular 'Hermione Mudblood Scar Fanfic' could be one where Hermione uses her intelligence, often taunted by the 'Mudblood' slur, to help Harry (the one with the scar) in a unique magical mystery. Maybe she deciphers an ancient spell that is key to defeating a new dark threat.
There's a fanfic called 'Hermione's Heroism'. It details how Hermione risks everything to save Ron when he's been poisoned. The author does a wonderful job of showing Hermione's determination and her love for Ron through her actions. It also has a really interesting sub - plot about Hermione exploring some ancient magic to find the cure.
There's a fanfiction I read where Ron and Hermione are getting married and Harry and Ginny are helping with the preparations. It has some really sweet moments like when Harry gives Ron some advice on married life based on his own experiences with Ginny. And there are also some funny parts where Ginny teases Hermione about her wedding jitters.
There's also 'Mudblood Magic'. This fanfiction focuses on Hermione using her so - called'mudblood' status to her advantage in a unique way. It shows how she and Ron's relationship evolves as she becomes more confident in her own identity. It has a lot of interesting plot twists and engaging dialogue.
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.
