In a fanfiction with this theme, it could be set post - war. Draco and Hermione find themselves in a situation where they are on the run from some dark wizards who are after them for different reasons. During their escape, Hermione gets wet and cold. Draco, having a change of heart after the war, gives her his warm cloak. This act of kindness begins to break down the barriers between them, and they start to have deeper conversations, realizing they have more in common than they thought.
Perhaps there's a fanfiction where a powerful and dark wizard from outside the school is targeting Muggle - borns. Hermione, being a Muggle - born, is understandably afraid. Draco, who has always had a complex relationship with Hermione, is conflicted. He doesn't want to see her hurt because, deep down, he has feelings for her. He ends up using his Slytherin cunning to outwit the dark wizard and keep Hermione safe.
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.
In a different fanfiction, Hermione could be afraid of a prophecy that involves her and Draco. The prophecy seems to foretell doom and destruction. She's terrified of what might come to pass. Draco, who also hears about the prophecy, tries to comfort her. He tells her that prophecies can be misinterpreted and that they can change their fate together. He starts to work with Hermione to figure out a way to avoid the bad outcomes predicted by the prophecy.
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.
It depends on the specific plot of the fanfiction. It could be a friend who turns against her due to jealousy, or perhaps a false ally within the so - called 'light' side who has ulterior motives.
One possible scenario in this fanfiction could be that Hermione is put under a dark spell that makes her feel weak and helpless. Draco, who has his own complex feelings towards her, could be conflicted about whether to help or take advantage. Maybe he initially tries to use her vulnerability but then realizes his true feelings and decides to protect her instead.
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.
Perhaps Hermione discovers she has a special connection to an ancient sorceress lineage. As she delves deeper into this, she uncovers secrets about the wizarding world's past and her own destiny. This plot would involve a lot of mystery and self - discovery for Hermione. It could also lead to her having to make difficult choices about how to use the knowledge she gains.
