She would probably surround the child with a network of trustworthy friends. Harry and Ron could be part of that. Their combined influence and power in the wizarding world could act as a deterrent to those who might want to harm the child. Hermione would also use her own reputation as a brilliant witch to vouch for the child's good nature.
Well, it might be good because it could have an interesting take on the characters of Hermione and Fenrir. Maybe it explores their relationship in a unique way that we haven't seen before in the original works.
In many such fanfictions, Hermione might start by trying to understand Fenrir's situation from a research perspective. She could be using her extensive knowledge of magic and werewolves to figure out a way to help him. For example, she might look into any spells or potions that could ease his lycanthropy symptoms.
Well, in many such fanfictions, the Weasleys might protect Hermione by using their magic skills. For example, they could create protective spells around her when she's in danger. They might also physically stand in her way when she's facing threats, like some dark wizards. And they would use their family influence in the wizarding world to keep her safe from any kind of harm or discrimination.
At the start, Hermione would be appalled by Fenrir's cruelty. She would be enraged that he has caused so much harm to innocent people. But as she delves deeper into getting to know him, she would start to see the complex web of factors that contributed to his behavior. She might see the neglect and discrimination he faced as a werewolf, which could make her feel a bit of pity. However, she would still firmly oppose his cruel actions and try to find a way to either contain or reform him, all while being acutely aware of the danger he poses.
Another theme is the idea of redemption. Many fanfictions explore whether Fenrir can be redeemed through his interactions with Hermione. It's about whether love or friendship can change a character who has been on the wrong path for so long.
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).
Fenrir might be intrigued by Hermione fanfiction because Hermione is a very intelligent and powerful character. Fanfictions often explore her potential in new and exciting ways, like her delving into different branches of magic or having unique adventures. This would be interesting to Fenrir as he may be curious about how she uses her wits and magic in these alternate scenarios.
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.
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.
