One idea could be that Hermione is on a mission and her car breaks down in the middle of nowhere. Scabior, who is on a different path at that moment, comes across her. He initially has his Death Eater instincts but then is intrigued by Hermione. They end up having to work together to fix the car and during that time, they start to understand each other better. This could lead to a series of adventures as they both have their own secrets and goals.
Well, they could meet in a car in a really strange way. Maybe Hermione accidentally Apparates into a car that Scabior is in. She's shocked and he's equally surprised. But instead of fighting right away, they start talking. Scabior is curious about this powerful witch and Hermione is trying to figure out how to get out of this situation. It could be a start of a very odd relationship in the fanfiction world.
Some writers might give Scabior a bit more depth. He could be a complex character who has his own reasons for kidnapping Hermione that are not just pure evil. For example, he might be in a difficult situation where he has to do this to protect someone he cares about. But still, he remains a morally grey character who is causing harm to Hermione.
The arm around the waist might symbolize possession. Scabior could be staking his claim on Hermione in the eyes of others in the fanfiction. It could be a power move, showing that he has some sort of control over her.
One possible plot could be that Hermione uses her magic in creative ways to try and escape. For example, she might use a spell to create a diversion among Scabior's henchmen and then make a run for it. Another idea is that her friends, like Harry and Ron, are on a desperate search to find her. They could encounter various obstacles and allies along the way.
One possibility is that in this fanfiction, Scabior has an ulterior motive for putting his arm around Hermione's waist. Maybe he's trying to use her to get to Harry Potter. He could be pretending to be friendly while secretly plotting. However, Hermione being the intelligent witch she is, might be aware of his true intentions and be planning her own counter - move.
In such fanfiction, Hermione is often highly intelligent. Her knowledge of magic and her ability to think on her feet are usually emphasized. For example, she might solve complex magical puzzles that others can't.
There could be a fanfiction where Hermione gets tattoos during her travels after Hogwarts. She meets Fleur during one of these travels. Fleur, who has always been seen as the more glamorous one, is a bit jealous of Hermione's new edgy look. However, as they get to know each other better, they realize that their differences in appearance are just surface - level, and they become good friends. Hermione's tattoos could be a story of her adventures, and she shares these stories with Fleur.
In most 'hermione and theo fanfic', Hermione is often depicted as highly intelligent, strong - willed, and very passionate about knowledge and justice. Theo, on the other hand, is usually shown as a complex character. He may be brooding, having a troubled past from his Slytherin upbringing, but also having a hidden depth of kindness and a desire for something more than the typical Slytherin values.
Hermione could become withdrawn. She might isolate herself from her friends for a while, spending her time in the library trying to make sense of it all. She might also feel a sense of betrayal, especially if they had some sort of understanding or relationship developing.
