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 Hermione could become more withdrawn or vengeful, and Ron would have to face the consequences of his actions, either through guilt or the backlash from other characters.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.
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.
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 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.
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.
In 'Shadows of Hogwarts', Snape's complex relationship with Hermione leads to this situation. The fanfiction delves deep into the reasons behind Snape's use of the term. It could be due to his own internal struggles, his past traumas, or his misplaced loyalty. But it also showcases Hermione's resilience in the face of such blatant discrimination.
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.
Hermione would probably be furious. She's not one to take such an insult lightly. She might immediately retaliate with a scathing comeback, using her intelligence and quick wit to put Lavender in her place.
In some fanfictions, this incident could be a turning point for Hermione. She might decide to focus more on her studies and magic skills, distancing herself from Ginny and those who tolerate such slurs. This could then lead to her achieving great things on her own, away from the drama, and eventually making Ginny realize the mistake she made.
