In fanfiction, Draco may save Hermione from Greyback because he has developed some feelings for her. These feelings might have been growing slowly over time as he saw her in different situations at Hogwarts. When it comes down to it, he can't bear to see her hurt by Greyback. Also, he could be trying to make amends for his past actions. Saving Hermione could be his way of starting to redeem himself in his own eyes and in the eyes of others. It's a big step towards changing his image from a typical Slytherin bully to someone with a bit of a heroic side.
One possible motivation is a sense of morality that Draco has buried deep inside. Despite his upbringing in a family of Death Eaters, he still has a conscience. Seeing Greyback about to harm Hermione, who is essentially an innocent in the face of such a brutal werewolf, stirs that conscience. Another factor could be his own self - interest. He might realize that by saving Hermione, he could gain some sort of leverage or protection in the complex world of the wizarding war.
Love. In fanfictions, it's a common motivation. Draco might have fallen in love with Hermione over time, and that love drives him to risk his life to save her from Voldemort.
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.
In many fanfictions where Draco saves Hermione from Greyback, it often starts with a situation where Hermione is in immediate danger from Greyback. Draco, perhaps having a change of heart from his Slytherin ways, decides to intervene. He might use his knowledge of the Death Eaters' plans or the layout of the area to his advantage. For example, he could lead Hermione to a secret passage that Greyback doesn't know about. This event can be a turning point in their relationship, leading to a newfound respect and sometimes even the start of a romantic connection between them, as they both realize there is more to each other than they initially thought.
I really liked 'Hermione's Encounter with Greyback'. In this fanfiction, Hermione is put in a difficult situation where she has to outwit Greyback. The author does an amazing job of showing Hermione's intelligence and resourcefulness. It's a short but engaging read.
Well, start by coming up with an interesting plot twist that keeps readers on the edge of their seats. Make the characters' emotions really intense and relatable.
Well, perhaps Snape uses his position as a teacher to step in. He could have been observing the situation secretly and when Draco was about to do something harmful to Hermione, Snape intervened with a firm command or some magic spell to stop Draco in his tracks.
One reason could be Snape's sense of justice. Despite his often - cold exterior, he might not tolerate Draco's bullying behavior towards Hermione.
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.
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.
The theme of the outsider is often present. Hermione, as a Muggle - born in the wizarding world, and Greyback, as a werewolf shunned by society, are both outsiders in a way. Fanfictions may explore how they connect on that level. Additionally, the theme of mystery is common. There's always the mystery of what Greyback will do next and how Hermione will react, which keeps readers on the edge of their seats.
