In the fanfiction, perhaps Hermione is sent to the supply closet as a punishment by Snape. Once inside, they find themselves trapped due to a malfunctioning locking spell. As they try to get out, they have to rely on each other's skills. Snape might be impressed by Hermione's quick thinking and Hermione could gain a new understanding of Snape's strict nature.
It could be that there is a mystery surrounding the supply closet itself. Hermione and Snape are both drawn to it for different reasons. Snape suspects some dark magic is at play in there, and Hermione is simply curious. When they are in the closet together, they start to explore and uncover secrets about Hogwarts' past that are somehow connected to the closet, and their relationship evolves throughout this adventure.
Well, one possible plot could be that Hermione accidentally stumbles into the supply closet while Snape is already there. Maybe she's looking for a particular potion ingredient. They start off bickering as they usually do, but then they discover a hidden magical object in the closet that requires both their knowledge to figure out. This could lead to a grudging respect between them.
At first, their relationship would likely be tense. Snape is known for his dislike of Gryffindors, and Hermione is a prime example of a Gryffindor student. But being in the close quarters of the supply closet might force them to communicate more directly. They could start to see past their initial prejudices. Maybe Snape would recognize Hermione's intelligence and Hermione would see that Snape has reasons for his cold exterior.
Well, one possibility is that they could have an intense conversation. Maybe Hermione discovers a side of Snape she never knew. For example, Snape could reveal some of his past traumas or secrets that make Hermione see him in a new light. It could be a moment of mutual understanding between two characters who didn't get along well in the original story.
It's also possible that their interaction would be filled with mystery. Snape has so many secrets, and Hermione is curious by nature. She might try to pry into his secrets, while Snape tries to keep her at bay. This cat - and - mouse game could add an interesting layer to their time in the closet.
One possible plot could be that Hermione is struggling with the pressures of her studies and the ongoing battle against the Dark Arts. Snape, being a complex character, might notice her distress in his own way. Maybe he initially dismisses it but then realizes she's in a deeper state of depression. He could then use his knowledge of potions to try and help her, leading to an unexpected bond between them.
One possible plot could be that Snape discovers Hermione has been sneaking into the restricted section of the library for some research that could get her in big trouble. He threatens to expose her to the school authorities unless she does his bidding, like helping him with some dangerous potions experiments. This would put Hermione in a difficult situation as she doesn't want to break the rules further but also doesn't want to get in trouble.
A great plot twist could be that younger Snape actually has some knowledge of Hermione's time - traveling. Maybe he's been having strange dreams about the future and when he meets Hermione, he realizes she's part of it. This would completely change the power dynamic between them.
Well, it could start with a medical emergency for Hermione that brings her to Snape's doorstep. From there, their interactions could reveal hidden aspects of their characters and build a complex relationship. Maybe there's a mystery illness or a series of challenging cases that they have to solve together.
There are quite a few fanfictions with this plot. Some focus on how Hermione discovers the truth about her parentage and how it affects her relationship with Snape. Others explore how the wizarding world reacts to this revelation. It's really a fascinating concept that allows for a lot of creativity in the fanfiction world.
Maybe in a time - travel fanfiction. Hermione travels back in time and ends up in Snape's student days. She tries to change some events for the better, and in the process, she gets to know a younger Snape. Their interactions are initially rocky but gradually turn into something more, leading to a kiss. This would be a very different take on their relationship, as it involves a different time period and different versions of themselves.
Maybe Hermione has lost her confidence in her magical abilities due to some traumatic event. Snape, in his own gruff way, decides to mentor her. He helps her recover by guiding her through difficult spells and magical concepts she had previously mastered but forgotten. This journey of recovery could also involve them exploring parts of Hogwarts that are little - known, and in the process, they form an unlikely friendship.
