One possible plot could be that Hermione is captured and brought to the Malfoy Manor. Draco, having some internal conflict due to his growing feelings for Hermione despite their past enmity, tries to protect her from the other Death Eaters in the Manor. Maybe they end up having to work together to escape some dark magic trap set within the Manor.
In this fanfic, it could start with Draco inviting Hermione to the Manor for some reason, like to discuss a truce between the Gryffindors and Slytherins. Once at the Manor, they find themselves in the middle of a family feud among the Malfoys. Draco and Hermione then have to rely on each other to navigate through the dangerous family politics while also dealing with their own feelings for each other that start to surface in this new and tense environment.
Perhaps in the fanfic, Hermione is on a secret mission at the Manor. Draco discovers her but instead of turning her in, he decides to help her. They start to understand each other better as they explore the secrets of the Manor together, like hidden passages or ancient spells inscribed on the walls. As they face various challenges within the Manor, their relationship slowly evolves from hatred to something more complex.
It could be a plot where Draco and Hermione are forced into a situation where they have to rely on each other's knowledge. Their 'tongue' in this case might refer to their quick - wittedness. For instance, they might be in a magical maze and need to solve puzzles by using their combined intelligence, which then leads to a new - found respect for each other.
Well, perhaps it could be a fanfic where they are on a secret mission together. After getting dirty during the mission, they find a single shower area in an old, abandoned building. They have to take turns, but there are some magical artifacts in the shower that start causing strange things to happen. Harry might be the first to notice something odd, Hermione would try to analyze it, and Draco would be reluctantly involved.
One possible plot could be that they are forced to work together on a post - war project in the wizarding world. At first, they still have their old grudges but as they spend more time together, they start to see each other in a new light. Eventually, they fall in love and have a baby. Their baby could then be a symbol of a new era of unity between the former rival houses in Hogwarts.
The plot could start with Hermione being in a dangerous situation near water, like she might be attacked by a water - based dark creature while near a lake at Hogwarts. Draco, who might be nearby for some reason, overcomes his initial hesitations (due to their past enmity) and jumps in to save her. After that, they could start to see each other in a new light, leading to a slow - burn relationship as they deal with the aftermath of the incident and the reactions of their friends and the Hogwarts community.
A really interesting scenario would be if they are trapped in a magically sealed room in the Manor. With no way out, they are forced to talk about their past misunderstandings. As they do, they realize how much they misjudged each other. They also find some old potions ingredients in the room and Hermione, being brilliant at potions, tries to brew a way out while Draco assists her in a rather clumsy but endearing way.
One thing that makes it interesting is the contrast between their backgrounds. Hermione, a Muggle - born with strong values of equality and knowledge, and Draco, a pure - blood from a family with a long history of prejudice. When they come together as mates in the context of Malfoy Manor, it creates a lot of tension and potential for character growth. They have to overcome their initial differences and the expectations of their respective social groups.
Perhaps a plot twist could be that Draco is under the influence of a dark spell when he kidnaps Hermione, and as she tries to break the spell, she uncovers a conspiracy within the wizarding world. Or it could be that the kidnapping is a ruse set up by Hermione herself to infiltrate the Slytherin group, but Draco doesn't know it and things spiral out of control.
One possible plot twist could be that Draco's family initially opposes the marriage. His pure - blood - supremacist parents might have a hard time accepting Hermione, a Muggle - born. Another twist could be that there are dark forces at play trying to use their union for some evil purpose, perhaps related to an ancient prophecy. And a third twist could be that Hermione discovers a long - lost family secret that has some connection to the Malfoy family, which changes the dynamics of their relationship and the marriage.
In fanfics where Hermione is Draco's mate in Malfoy Manor, it could begin with a situation where Hermione discovers a side of Draco that no one else has. Maybe he shows a bit of kindness towards her when she's in a vulnerable position at the Manor. This small act could make Hermione re - evaluate her view of him. At the same time, Draco might be intrigued by Hermione's intelligence and tenacity. Over time, these feelings grow and they become mates, often defying the social norms of the wizarding world.
One possible plot could be that Draco, for some reason, becomes Hermione's servant. Maybe it's part of a magical pact or a punishment from the wizarding world. Draco, being used to his pure - blood superiority, would initially resist but gradually learn to respect Hermione's intelligence and kindness. They could then go on adventures together, facing various magical threats and learning more about each other's true natures.
