The bite could be a catalyst for Hermione to explore the darker side of the wizarding world. She may seek out other werewolves, trying to understand their community. This could lead to her getting involved in werewolf politics, which is something not many wizards are aware of. It might also put her in danger as there could be werewolves who don't want a Muggle - born like her poking around. On a more personal level, it could cause a rift between her and her parents. She may be afraid of hurting them, so she distances herself, and this emotional turmoil would be a significant part of the fanfiction's narrative.
Well, it might lead to a divergence in the fanfiction's story arc. Hermione could become more isolated as she tries to hide her condition. She might start to study more about werewolves on her own, delving deep into the Forbidden Section of the library. This could uncover secrets about werewolves that no one else knew, which could be a major plot point. Also, her magical abilities might be affected. There could be a new, darker side to her magic because of the werewolf bite, and she'd have to learn to control it. This would add a whole new layer of complexity to her character and the overall story.
One possible plot could be that Fenrir, for some reason, has a change of heart. Maybe he sees Hermione's kindness and intelligence during one of his encounters with the wizarding world. He starts to protect her secretly from other dark forces. And Hermione, initially afraid, gradually realizes there's more to him than just a monster.
One possible plot could be that Hermione stumbles upon Fenrir Greyback in a situation where he's about to be killed by some dark wizards who see him as a loose end. Hermione, being the empathetic and brave witch she is, decides to save him. Maybe she believes that every life is worth saving, even a werewolf like Fenrir. She could then try to rehabilitate him, using her vast knowledge of magic and her strong moral compass.
One possible consequence could be her transformation into a werewolf. In many werewolf lore within the Harry Potter universe, a bite from a werewolf like Fenrir Greyback often leads to lycanthropy. This would mean that Hermione would have to deal with the monthly transformations, and she would likely face discrimination from some in the wizarding world who are prejudiced against werewolves.
Well, perhaps Remus, in his werewolf form, accidentally bites Hermione during a full moon. Then he feels an overwhelming sense of guilt. He might isolate himself from Hermione and the others, fearing that he has put her in danger or turned her into a werewolf too. Hermione, on the other hand, could be in shock and dealing with the physical and emotional pain, but also trying to convince Remus that it's not his fault.
One possible plot could be that Fenrir Greyback, for some reason against his usual nature, discovers Hermione in a vulnerable state. Maybe she's been separated from her friends during a battle. He decides to keep her safe from other dark creatures, seeing some sort of potential in her that he doesn't want wasted. He might teach her some of the ways to survive in the wild, which are skills he has as a werewolf.
One possibility is that it's a story of redemption for Fenrir. He starts to watch over Hermione and in the process, he begins to see the good in people he's been trying to harm. As he watches her, he might be influenced by her kindness or her intelligence, and this gradually changes his view of the wizarding world and his place in it.
One possible plot could be Hermione's research on werewolves leading her to interact with Fenrir Greyback. Maybe she wants to understand the werewolf curse better and tries to interview him in Azkaban. Through their conversations, she discovers the dark and twisted past that led him to become such a feared and cruel werewolf.
In some fanfictions, she could be ostracized by the wizarding community due to the fear of her new condition. This could lead to her feeling isolated and having to fight for acceptance. Also, it might change her relationships with her friends. For example, Ron might be more overprotective while Harry could be more determined to find a cure for her.
Perhaps Hermione is on a mission to understand werewolves better in order to help them integrate into the wizarding society. In the process, she gets to know Greyback in a different light. He may be more complex than just a monster. They start to have feelings for each other. They secretly marry because they know that the wizarding community would not accept their relationship, especially considering Greyback's past actions. Their marriage could then be a story of trying to change the world's perception while also dealing with their own internal struggles.
A possible plot could be that Hermione gets bitten by Greyback accidentally. Instead of turning into a full - blown werewolf, she has some new abilities and a strange connection to Greyback. They then have to figure out how to deal with this new situation, while also facing the wizarding world's prejudice against werewolves. It could also involve Hermione using her intelligence to find a cure for herself and in the process, changing Greyback's view of non - werewolves.
