At first, their relationship would be very tentative. Hermione would be cautious as Snape has always been so strict and seemingly unapproachable. But as Snape starts to share his knowledge with her, she would begin to respect him more. Over time, they might develop a mutual understanding. Snape would see Hermione as a worthy protégé, and Hermione would see Snape as more than just a grumpy professor.
Perhaps Snape takes Hermione under his wing because he realizes she is being bullied by some Slytherin students for being a Muggle - born. He secretly protects her and in the process, they start to understand each other better. Snape could share his own experiences of being an outcast in Hogwarts when he was a student. This bond could then grow into a sort of friendship where Hermione learns to see past Snape's harsh exterior and Snape starts to respect Hermione's intelligence and tenacity even more.
Harry's character often develops a sense of trust. At first, he is likely to be very wary of Snape. But as Snape takes him under his wing, Harry starts to see Snape's good side. This makes him more open - minded and less quick to judge. He may also become more confident in his magic abilities as Snape imparts his knowledge. For example, if Snape teaches him advanced potions, Harry will feel more competent in that area.
One common theme is the idea of redemption. Snape, with his complex past, often finds a form of redemption through his relationship with Hermione. Another theme is the exploration of power dynamics. Hermione is a very powerful witch, and Snape is a highly skilled wizard, so their relationship can be about how they balance and learn from each other's power. And there's also the theme of the outcast. Both characters have felt like outcasts in different ways, and their relationship can be a way for them to find acceptance.
There may be some fanfictions with this concept that are written in a non - inappropriate way. However, such a premise can be quite controversial and not in line with the original spirit of the 'Harry Potter' series. It's important to look for fanfictions that uphold positive values.
Snape's care for his Slytherins can also be shown through his teaching methods. He may be strict, but in fanfiction, it's often with the intention of making them better. He could give extra tutoring to students who are struggling in potions or other subjects. He understands the Slytherin ambition and tries to channel it in a positive way, like encouraging them to pursue difficult but rewarding areas of magic study.
One great example could be a story where Snape secretly protects Hermione from some dark forces in Hogwarts that the other professors are unaware of. He might use his knowledge of the Dark Arts to counter any threats aimed at her.
Some writers create it because they like to explore the relationship between two very different characters. Snape is often seen as a complex and somewhat dark character, while Hermione is bright and eager to learn. The contrast can lead to interesting storylines.
One alternative could be Snape and Hermione forming a mentorship bond where Hermione willingly follows Snape's guidance in her magical studies. Another could be them teaming up to solve a mystery together without any force involved.
There could also be a plotline where Hermione discovers some of Snape's past traumas and in trying to help him, they form a bond. Snape, out of gratitude and a newfound respect for her, starts to take care of her like a mentor. He shields her from the harsh judgments of other Hogwarts professors and students alike, and together they work towards a better future for the wizarding world.
