Maybe it's a strict pure - blood supremacist. They see Hermione, a Muggle - born, in a relationship with Snape and decide to oppose it. They could try to use their influence in the wizarding world to create obstacles for the two, like getting Snape fired from his teaching position or expelling Hermione from Hogwarts.
It could be a dark wizard who is jealous of Snape's relationship with Hermione. This antagonist might try to break them apart by causing trouble in Hogwarts or spreading false rumors about them.
Yes, there might be some fanfictions that handle this scenario in a non - inappropriate way. Some writers may explore complex relationships or emotional moments between the characters in a more platonic or emotionally charged context that doesn't cross into inappropriate territory. However, it can be quite difficult to find among the vast sea of fanfiction, as the idea can be easily misinterpreted or taken in the wrong direction.
One possible scenario could be a moment of intense conversation where Hermione is sitting in Snape's lap and they are having a deep discussion about magic theory that only they understand. It might be a turning point in their relationship in the fanfiction world.
Maybe it's part of a game in a magical school event. Hermione and Snape are both involved in a sort of wizarding trust - building exercise where she has to land on his lap as part of a challenge. Then they have a conversation about the importance of trust between different houses in Hogwarts. This would be a family - friendly and positive take on the situation.
It could be due to a prophecy or a magical bond. Maybe there is a prophecy that says something about Hermione being in close physical proximity to Snape at a certain time. Or there is a magical bond that Snape discovers and he thinks that forcing her to sit on his lap is the only way to activate or understand this bond better, although these are all very strange and complex reasons within the realm of fanfiction.
It could be a dark wizard who discovers Hermione's hidden identity and wants to use it for his own evil purposes. Maybe he wants to harness the power that comes with her true identity to take over the wizarding world.
Perhaps a powerful magical being from a different realm is the antagonist. This being might mistake Hermione for someone else or see her as a key to something in the wizarding world. So, it uses its magic to make her disappear. This being would be very difficult to defeat or negotiate with, making it a huge challenge for those trying to find Hermione.
Another possibility is a dark wizard or a group of dark wizards who are after some powerful magic that the Lestrange family has, and Hermione gets in their way as she tries to protect the family or uncover the secrets. They would be the main force that Hermione has to face and overcome throughout the fanfiction.
Well, one way it could develop is that Hermione might initially be extremely resistant and angry. She could try to use her magic to get away from Snape. But then, perhaps Snape has some ulterior motive that is not as malicious as it seems at first, like he's trying to protect her from something and sitting on his lap is just a strange way of keeping her close. So, over time, Hermione might start to understand his intentions and they could form an unlikely alliance within the context of the fanfiction.
In some fanfictions, Snape is made out to be Hermione's father. Fanfiction writers often like to play with established relationships and create alternate backstories. This idea might be appealing as it adds a new layer of complexity to both characters' stories. It can lead to different interpretations of Snape's actions towards Hermione in the original series, like perhaps his strictness was a way of protecting his secret daughter in a way.
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.
