Well, it could be that Hermione discovers a secret about Draco related to Christmas. Maybe Draco has a special Christmas tradition from his family that he's been hiding. Hermione stumbles upon it and instead of using it against him, she helps him preserve it. This act of kindness makes Draco re - evaluate his views on Hermione. So on Christmas day, he gives her a small but meaningful gift as a thank you, like a rare book from the Malfoy library that Hermione has been wanting to read.
One possible plot could be that during a Christmas at Hogwarts, Hermione and Draco are paired for a special Christmas project. At first, they're hesitant and a bit hostile towards each other. But as they work together, they start to see different sides of each other. Draco might show his more vulnerable side, perhaps missing his family during the holidays. Hermione, with her kind heart, begins to understand him better. Eventually, they end up having a newfound respect for one another and share a quiet Christmas moment together, looking at the snow - covered Hogwarts grounds.
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.
The plot could start with Draco and Hermione realizing their mutual attraction despite their initial animosity. They might secretly plan their elopement to avoid the scrutiny and opposition from their friends and families. Maybe they find a magical place, like an ancient forest where they exchange their vows in a private ceremony.
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.
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.
A possible plot could be that Hermione is getting ready for a big wizarding event and her bra has some sort of magical enchantment on it. Draco accidentally discovers this when he's snooping around (he's still a bit of a troublemaker in this scenario). This discovery leads to a series of events where they have to work together to figure out who enchanted the bra and why. It could be part of a larger plot to embarrass Hermione or to gain some sort of magical advantage.
Maybe in the fanfiction, Draco is feeling lonely during Christmas break at Hogwarts as his family is in a bit of turmoil. Hermione notices this and decides to be kind. She invites him to join her and her friends for a Christmas celebration in the Gryffindor common room. At first, Draco is hesitant but then he realizes how much fun it can be to be part of a different kind of 'family' for the holidays.
One possible plot could be that their daughter is a young witch growing up in a world that still has remnants of the old wizarding world rivalries. She could struggle with being the daughter of two former enemies, facing prejudice from some in the wizarding community. She might have extraordinary magical abilities that draw both positive and negative attention, and she has to learn to navigate her own identity while also trying to bridge the gap between the Gryffindor and Slytherin legacies her parents represent.
One possible plot could be that during a potions class, Draco and Hermione accidentally mix the wrong ingredients. This could lead to a magical reaction that causes them to swap personalities. Hermione might start acting like Draco, being more aloof and sarcastic, while Draco could become more studious and rule - abiding like Hermione. They then have to figure out how to reverse the effect while also dealing with the chaos it causes in Hogwarts.
In the fanfiction, perhaps the Ministry of Magic has some concerns about Hermione and Draco adopting Teddy. Since Teddy is the son of Remus Lupin and Nymphadora Tonks, and with his werewolf heritage, they might have to go through a lot of red tape. Hermione, being the brilliant witch she is, would use her knowledge of the law to fight for their right to adopt Teddy. Draco, on the other hand, would use his family's influence and wealth in a more positive way this time. Teddy would start to see them as his real parents, and they would have to deal with the challenges of raising a magical child who has unique abilities and needs.
The plot could involve Teddy facing some sort of danger or mystery that only Hermione and Draco's combined skills can solve. For example, there might be a dark magic threat related to Teddy's family history. Hermione's research skills and Draco's knowledge of the wizarding elite could be crucial in uncovering the truth.
