Another theme is redemption. Snape's past actions might be redeemed through his new - found feelings for Hermione. Also, the theme of intellectual connection often comes up. Hermione's thirst for knowledge and Snape's vast magical knowledge can create a bond in these stories. Moreover, there could be a theme of secrecy as their relationship, if it develops, would be quite scandalous in the Hogwarts context.
There are many fanfictions on this theme. You can start by looking on platforms like Archive of Our Own (AO3). However, keep in mind that fanfiction quality can vary greatly.
A possible plot could involve Hermione inheriting Snape's potions skills in an even more profound way. She could use her combined intelligence from her mother and potions talent from Snape to create new spells or potions. Snape, as her father, would be torn between his loyalty to the Dark Lord (in some versions of the story) and protecting his daughter from the chaos of the wizarding war.
In fanfiction, the idea of Severus Snape kissing Hermione is quite an interesting and often controversial concept. Some fanfiction writers might explore this relationship as a way to break the boundaries of the original story's relationships. It could be a means of delving into a different side of Snape's character, perhaps showing a more tender or unexpected side of him.
Fanfictions involving Severus Snape and Hermione can take many forms. One common approach is to rewrite parts of the original story with their relationship at the center. This could involve changing the events at Hogwarts to bring them closer together. Another aspect is the character development. Hermione might become more empathetic towards Snape's past actions, and Snape could learn to see Hermione not just as a student but as an equal. It's all about reimagining the possibilities within the wizarding world.
In a fanfiction, Snape and Hermione might be paired up for a special project. Snape, initially hesitant, realizes that Hermione's thirst for knowledge and her ability to think outside the box could be useful. They could start off on a rocky note, with Snape being his usual sarcastic self and Hermione being defiant. But as they work together, they develop an understanding and respect for each other's skills.
One possible scenario in this fanfiction could be that Snape starts to notice Hermione's intelligence in a new way. He might see her constantly out - performing her peers in Potions class, which was his area of expertise. As he observes her more closely, he begins to admire her tenacity and thirst for knowledge. This newfound admiration could gradually turn into something more like affection.
There could also be a fanfiction where Snape and Hermione are both involved in a mystery within Hogwarts. They are forced to work together to solve it. Along the way, they learn more about each other's strengths and weaknesses. Snape might be impressed by Hermione's deductive skills, and Hermione might gain a new perspective on Snape as they collaborate.
Magic could play a role. There could be a magical spell or potion that was involved in Hermione's conception that links her to Snape. For example, a potion that alters memories and relationships. This would make for a very interesting and complex backstory in the fanfiction. Snape might not even be aware that he is Hermione's father at first, and when he discovers it, his whole view of her would change. He would have to deal with his feelings of protectiveness and his past actions towards her in Hogwarts.
One great fanfiction is 'The Unlikely Bond'. It delves into a scenario where Snape and Hermione have to work together on a secret project for Hogwarts' future. Their interactions are filled with Snape's usual sarcasm and Hermione's determination.
