A possible plotline could be Hermione getting captured by Greyback's pack. She then has to use her wits and magic to escape. Maybe she befriends a young werewolf within the pack and uses that connection to her advantage.
There could also be a plotline where Hermione tries to reform Greyback. She believes that there is good in him deep down. So, she spends time with him, teaching him about the wizarding world in a different way, and trying to change his violent nature.
One possible plotline could be that Fenrir takes Hermione as a hostage to use against the Order of the Phoenix. He might think that her connection to Harry Potter makes her a valuable bargaining chip. Another could be that he is under the control of a dark wizard who orders him to capture Hermione for some dark magic ritual. In some fanfictions, it could also be that Fenrir has some sort of personal vendetta against Hermione and takes her to exact revenge for something she did to him or his kind in the wizarding war.
Well, perhaps in the fanfiction, Fenrir Greyback is under the command of Voldemort to watch Hermione as she is seen as a threat to the Dark Lord's plans. He might follow her around Hogwarts, observing her every move. This could lead to some tense moments where Hermione senses she's being watched but can't quite figure out who it is at first. As the story progresses, she could start to set traps to catch her stalker, which would be Greyback. And there could be a big showdown between them in the end.
One common plotline could be Hermione finding ways to outwit Fenrir Greyback. For example, she might use her intelligence and knowledge of magic to set traps or create diversions. Another could be other characters coming to Hermione's rescue, like Harry and Ron realizing she's in danger and using their skills to protect her from Greyback.
One possible plotline could be an alternate universe where Fenrir Greyback is redeemed early on. Maybe he has a moment of self - realization and decides to change his ways. He meets Hermione during this transformation process, and she initially distrusts him but gradually sees his efforts to become a better being. Their relationship could develop as she helps him fully embrace his new, non - violent self.
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.
One possible theme is redemption. Maybe the fanfiction explores the idea of Greyback being redeemed through his interaction with Hermione. This could be appealing as it shows the power of goodness (represented by Hermione) over evil.
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.
In some fanfictions, the relationship between Hermione and Greyback might be a dark and twisted one. It could be used to show the contrast between good and evil in the wizarding world. However, this also poses challenges in terms of character development. Writers need to be careful not to stray too far from the established personalities of the characters in the original Harry Potter series.
Maybe it's a post - Hogwarts story where Hermione, in a more grown - up and jaded world, takes up smoking as she faces the challenges of the wizarding world politics or her own personal demons. It could be a way for the author to show her in a more complex and less - than - perfect light, adding a new dimension to her character.
One possible plotline could be Hermione getting to know Dolohov in an alternate universe where he has a different side to him. Maybe she discovers some hidden good in him and tries to redeem him.
