In a fanfiction, Snape might want to help Hermione when she is wrongly accused of stealing powerful magical artifacts. Snape, knowing her character, decides to use his skills as a Potions master and his knowledge of the castle's secrets to find the real culprit and clear Hermione's name. He could be motivated by his new - found respect for her intelligence and her Muggle - born status which he has come to understand better over time.
Hermione could start by showing her genuine intentions. For example, she could offer to help Snape with his potions research without asking for anything in return. Since Snape is passionate about potions, this might pique his interest and make him less resistant.
Their relationship could start off very tentatively. Snape would be his usual gruff self, but Hermione would notice his small acts of help. As time goes on, she might start to trust him more and they could develop a sort of mentor - mentee relationship, with Snape passing on some of his more esoteric knowledge of magic to Hermione.
A plot could be that Snape is suffering from some sort of post - war trauma that no one else seems to notice. Hermione, being the observant and empathetic person she is, decides to help him. She tries different methods like introducing him to Muggle therapies she has read about, or using calming spells and potions she creates herself. As she helps him, Snape begins to open up about his past, his feelings for Lily, and his experiences during the war, which in turn helps Hermione understand him better.
Their relationship could start off with a lot of tension. Snape has always had a bit of a prickly relationship with students, especially those he sees as being too much like Gryffindors. However, as they are forced to collaborate, they might find common ground in their love for knowledge. Snape is a highly skilled wizard in many areas, and Hermione is eager to learn. This shared interest could be the starting point for a more amicable relationship.
One possible theme could be redemption. Snape, who has a complex past, might see Hermione as a way to redeem himself. Maybe he realizes her intelligence and potential and wants to guide her in a different way than he does with other students.
Yes, there are. You can find them on various fanfiction websites. One interesting aspect in these stories could be how they overcome the age gap and the initial animosity Snape had towards Hermione in the original series. It often involves character development for both of them.
He could also be a bit sarcastic in his response. Snape has a sharp tongue, so he might say something like 'Miss Granger, what makes you think I have the time or inclination to help you?' But as Hermione explains her situation, he might gradually soften, realizing the seriousness of the matter. Maybe he starts to see a bit of himself in Hermione's thirst for knowledge.
One common theme is the power imbalance. Snape is a powerful and often intimidating figure, and Hermione is a brilliant but still young witch. The fanfictions often play on this dynamic, exploring how power can be both alluring and dangerous in a relationship.
