A storyline could be that Snape needs Hermione's help to uncover a long - hidden secret in Hogwarts. Since she's so intelligent and resourceful, he enlists her help, and she has to follow his every instruction to get to the bottom of it.
Perhaps Snape has made a deal with some dark forces to protect Hogwarts, and as part of that deal, he needs Hermione to perform certain tasks. She, being the selfless Gryffindor she is, reluctantly agrees to do what he wants to safeguard the school. This could lead to a lot of internal conflict for Hermione as she struggles with Snape's morally ambiguous requests.
In the context of fanfiction, it could be a very interesting character study. Hermione is known for her strong will, so seeing her in a situation where she has to do whatever Snape wants could show a different side of her. It might also give more depth to Snape's character, as we see how he interacts with Hermione in this unorthodox situation.
One potential storyline could be Hermione's discovery of her true heritage. She might start noticing strange similarities between herself and the Notts, or find some hidden family heirlooms. This could lead to a journey of self - discovery as she tries to figure out why she was kept away from her true family. Another storyline could involve the reaction of her friends, especially Harry and Ron. They might be initially shocked and skeptical, but then support Hermione as she delves deeper into her past. The Notts, on the other hand, could be conflicted about accepting Hermione, especially if they have different beliefs or values.
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.
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.
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.
One common theme is redemption. Snape, with his complex past, might find redemption through his relationship with Hermione. Another is the breaking of stereotypes. Hermione is a Muggle - born and Snape has his own prejudices which are overcome.
One possible storyline could be that in a hidden corner of Hogwarts, Snape discovers Hermione's secret project related to advanced potions. This could lead to a begrudging respect as he sees her intelligence and determination, similar to how he respected Lily. Another could be Hermione stumbling upon Snape in a corner where he is reminiscing about his past, and she gains a new understanding of his character.
Perhaps in the fanfiction, Hermione accidentally enters Snape's private chambers and finds evidence of his lonely past. She feels sorry for him and decides to use her intelligence to create a magical project that could bring some joy into his life. This project could involve something like a memory - sharing device where Snape can relive his happier memories, and in the process, he and Hermione form a unique connection.
A third storyline could be a political intrigue one. In a post - Voldemort wizarding world, there are still power struggles. Hermione, now a prominent figure in the Ministry of Magic, has to deal with Lucius who is trying to regain some of his former influence and Snape, who is caught in the middle. Hermione tries to uphold the new, more inclusive laws of the wizarding world, while Lucius schemes to undermine her. Snape, with his knowledge of both sides, has to decide where his loyalties lie.
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.
