Well, some fanfictions might explore alternate timelines where Hermione takes on that role and has unique adventures and relationships with Severus. It's all about creative imagination!
The storylines can vary widely. It could be that Hermione's being 'the girl who lived' changes the dynamics at Hogwarts and leads to complex friendships or conflicts with Severus. Maybe it even affects the magical world's politics and their roles in it.
One interesting storyline could be Snape taking Hermione on as a special apprentice of sorts. He sees her potential in potions and dark arts defense far beyond her years and decides to privately tutor her. This could lead to a series of adventures where they explore ancient spells and potion-making techniques together.
One great fanfiction is 'The Unlikely Bond'. It delves into a scenario where Snape and Hermione have to work together on a secret project for Hogwarts' future. Their interactions are filled with Snape's usual sarcasm and Hermione's determination.
The best fanfictions in this regard also play with the themes of redemption and understanding. Snape has a complex past, and Hermione is a character who is always seeking knowledge. When a fanfiction can combine these elements, like Snape finding some form of redemption through his interactions with Hermione or Hermione learning something new about human nature from Snape, it really stands out.
One challenge is character consistency. Snape is a very complex and often brooding character, and Hermione is intelligent and headstrong. Keeping their personalities true to the original while developing a romantic relationship between them can be difficult. For example, Snape's past traumas and his loyalty to Lily Potter might make it hard for him to open up to Hermione.
Perhaps in a story where there's a spell gone wrong. The spell causes Snape and Hermione to be linked in a strange way. They start to experience each other's emotions and memories. As they work together to break the spell, they develop a deep connection and Snape, who has always been a complex character, shows a softer side and kisses Hermione as a sign of his new - found feelings.
One popular example could be 'A Different Kind of Bond'. In this fanfiction, it explores how Hermione's intelligence and Snape's hidden depths draw them together in a unique relationship. It often delves into their shared love for knowledge and how they overcome the initial animosity from their Hogwarts days.
Well, a common plot is Hermione being sent back in time to Snape's student days. This can lead to her trying to change his future, or just trying to survive in a different era while dealing with a young and moody Snape. There are also fics where Snape is tasked with mentoring Hermione privately, and their relationship evolves from one of mutual dislike (on Snape's part at first) to respect and even friendship. Some fanfictions also explore the idea of a magically - forced bond between them that makes them understand each other better.
Another storyline might involve an owl that has a special connection to Snape. Hermione notices the strange behavior of the owl towards Snape and starts to investigate. As she delves deeper, she uncovers some hidden aspects of Snape's life that change her perspective of him. This could lead to a friendship or a begrudging respect between them.
In a fanfiction, Snape and Hermione might be paired up for a special project. Snape, initially hesitant, realizes that Hermione's thirst for knowledge and her ability to think outside the box could be useful. They could start off on a rocky note, with Snape being his usual sarcastic self and Hermione being defiant. But as they work together, they develop an understanding and respect for each other's skills.
