I'm not sure of the exact name, but in some fanfictions, Fenrir Greyback saves Hermione because she has some sort of information that he needs. For example, she might know the location of a powerful magical artifact that could change the power balance in the wizarding world. Greyback saves her from a dangerous situation in order to get that information from her. However, as he spends time with her, he starts to have a strange sense of protectiveness towards her that he didn't expect.
There's a fanfiction called 'Greyback's Redemption Arc'. In it, Fenrir Greyback saves Hermione from a group of Death Eaters. The author might have written it to explore the idea of redemption for a character like Greyback. Maybe he saves Hermione because he sees her as a symbol of the good in the wizarding world that he has lost touch with, and this act of saving her could be the start of his journey towards redemption.
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 interesting fanfiction could be 'The Unlikely Pursuit'. In this, Fenrir's pursuit of Hermione is a complex web of dark intentions and her attempts to outwit him. It really plays on the danger and mystery of Greyback's character.
One popular fanfiction in this vein might be 'The Greyback Incident' which delves into the dark encounter between Fenrir Greyback and Hermione. In this story, it shows how Hermione uses her wits to try and escape the clutches of Greyback. However, the overall tone is quite tense and filled with a sense of danger as Hermione is in a very perilous situation.
Hermione's character could develop in terms of her understanding of the grey areas between good and evil. Saving Fenrir goes against the common perception of him as a monster. This could make her more open - minded and less judgmental. She might start to see that even the most feared creatures can have a chance at redemption.
There are not many mainstream fanfictions specifically about Fenrir Greyback just watching Hermione. But in some dark - themed fanfiction collections, you might find stories where he spies on her as part of a larger, more sinister plot against the wizarding world. These stories usually involve Hermione having to outwit him and his evil intentions.
Perhaps it's the allure of the 'forbidden'. Fenrir Greyback is a dark and dangerous character, and exploring his relationship with Hermione in fanfiction might be an exploration of the contrast between light (Hermione) and dark (Greyback).
In one fanfiction concept, Greyback saves Hermione when she is trapped in a magical maze created by dark wizards. Greyback, being a cunning and experienced dark creature, is able to navigate the maze and get to Hermione before the maze collapses or she is killed by the various traps inside. He might save her because he senses that she has a great potential that could be useful to him in the future.
