If Hermione was sorted into Slytherin, she'd bring a whole new dynamic to the house. Slytherin is known for its ambition and resourcefulness, and Hermione has those traits in spades. She might change the perception of what it means to be a Slytherin. Instead of just being about pure - blood supremacy and cunning for the sake of it, she could introduce a more ethical form of ambition. Her study habits would probably influence some of the other Slytherins to be more studious. And she'd also have to navigate the politics within Slytherin, which could be a real challenge as she's used to the more straightforward environment in Gryffindor.
One popular Gryffindor and Slytherin love fanfiction is 'The Green and the Red'. It tells the story of a Gryffindor girl and a Slytherin boy who are paired for a school project and gradually fall in love. Another is 'Unexpected Love', where a Gryffindor Quidditch player and a Slytherin prefect find common ground and develop feelings for each other.
I've also read 'Green and Red: A Slytherin - Gryffindor Love Story'. Here, Ginny is initially skeptical of Harry being in Slytherin. But as the story progresses, they discover they have more in common than they thought. The fanfic delves into their personal growth, their love for Quidditch which becomes a connection point, and how they overcome the house rivalries to be together.
Another theme is friendship and loyalty. Despite their differences, they were friends and founders of Hogwarts. Fanfictions like to show how their loyalty to each other and to Hogwarts itself was tested and strengthened over time. For example, some stories show how they supported each other during difficult times in the school's early days.
In terms of values, a female Malfoy in Gryffindor would value courage and chivalry over the Slytherin values of ambition and cunning in a different way. While a Slytherin Malfoy would use cunning to achieve their ambitions, often in a self - serving way, a Gryffindor Malfoy would use her courage to fight for others. For instance, she would be the first to volunteer to help in a dangerous situation in Hogwarts, like when there is a dark creature loose, rather than thinking about how it could benefit her like a Slytherin might.
One plot twist could be that there's a prophecy about a Slytherin and a Gryffindor uniting the wizarding world, which is revealed to be about Harry and Ginny. This forces them to deal with a lot of attention and expectations from the wizarding community. It also makes their relationship a focal point of a much bigger plot, with dark forces trying to stop them from fulfilling the prophecy.
One popular 'salazar slytherin x godric gryffindor fanfiction' is 'The Founders' Bond'. It delves deep into their relationship, exploring how their different ideologies initially clashed but later led to a deep understanding and a bond that was more than just friendship. It's a great read for those interested in this pairing.
Often, these stories show the characters initially being influenced by the house stereotypes. For example, the Gryffindor might be seen as too brash and the Slytherin as too sneaky. But as the story progresses, they see beyond that. They learn that the Gryffindor's courage can be a good influence on the Slytherin's ambition, and the Slytherin's cunning can help the Gryffindor in different situations.
Well, at first, most of Harry's Gryffindor friends would be taken aback. They have always had a certain animosity towards Slytherin. But as time goes on, if they see that the Slytherin Harry is betrothed to is kind - hearted and doesn't hold the same prejudices as some of the other Slytherins, they might start to come around. For instance, Seamus might start to joke around with the Slytherin, and Dean could start to include them in group activities. It would be a slow process of acceptance as they get to know the Slytherin better through Harry.
Well, it shows that the Gryffindors won't tolerate the Slytherin's typical sneaky behavior, as represented by Draco. When they stand up to him, it's like a direct challenge to the Slytherin way of doing things. It heightens the rivalry as the Gryffindors are showing they won't be pushed around by the Slytherins.
