Hermione is the central figure here as she is the one driving the action. She is likely to be portrayed as a bit more feisty and assertive than in the original books. Snape is also a main character as he is the target of Hermione's outburst. However, other characters like Harry and Ron might also make appearances. They could be the ones who witness Hermione's confrontation with Snape or even be involved in the events that lead up to it. For example, Harry might tell Hermione about something unfair Snape did, which then prompts her to act.
One possible plotline could be that Hermione stands up to Snape for constantly being unfair to Gryffindor students. Maybe she discovers some misinformation he has spread about her friends and confronts him publicly in the Great Hall, causing a stir among the students and teachers alike.
Perhaps a scene where Hermione confronts Snape about his treatment of her friends. In the fanfiction, she could gather evidence of how Snape has been singling out Harry or Ron, and then she barges into his office. She would start off calmly, but as Snape tries to dismiss her, she gets more and more passionate, really telling him off for his behavior.
Hermione's character development in these fanfictions can be complex. When she tells Snape off, she may face consequences that force her to grow in different ways. For instance, Snape could try to retaliate by making her academic life difficult. This would make her learn how to deal with adversity and still stay true to her principles. She might also start to question some of the school's rules and traditions, as she realizes that someone in a position of authority like Snape can misuse them. This leads to her becoming more of a rebel and a reformer within the Hogwarts community, which is a significant development from her initially rule - abiding self.
One great Snape and Hermione fanfiction is 'The Unbreakable Bond'. In this story, Hermione discovers a hidden side of Snape during her research in the Hogwarts library. Their relationship starts as a mentorship but gradually evolves into a deep friendship that defies the expectations of the wizarding world. It beautifully portrays their individual characters and how they can complement each other.
The 'time - travel' trope is also quite common. For example, Hermione might go back in time and interact with a younger Snape, which can lead to all sorts of new storylines and character developments.
Hermione might become more guarded at first. She is used to being independent and suddenly being 'gifted' to Snape is a big change. But over time, she could learn to be more patient and understanding. Snape, on the other hand, might soften a bit. His usual cold exterior could crack as he gets to know Hermione better.
It's hard to say who would be the clear winner. Hermione is intelligent and quick - witted, but Snape has years of experience and a great deal of magical knowledge. If it's a battle of words, Hermione might hold her own for a while, but Snape could use his authority to shut her down.
She might give him cold stares in class. Hermione is not one to shy away from showing her emotions through her expressions. So, every time Snape is in her line of sight, she could fix him with a withering glare that clearly shows her displeasure.
One possible reason could be a misunderstanding. Maybe Hermione thought Snape was involved in some dark plot against her friends. In the wizarding world, there are often secrets and deceptions, and if she got some false information, it could lead her to take such drastic action.
