Hermione could accept out of curiosity. She's always been interested in knowledge and understanding people. This would be a unique opportunity to get to know Snape on a different level. Maybe she hopes to learn more about his past, his knowledge of the Dark Arts, or his reasons for being so harsh in class. It would be a chance for her to see if there's more to him than meets the eye.
She might decline. Hermione is a very practical and goal - oriented person. She has her studies and her friends to think about. Going on a date with Snape, who has a rather complex and not - always - friendly reputation, might seem too risky and not in line with her plans. Also, she may not have any romantic feelings for him at all.
One possibility is that Hermione would be extremely shocked. She might initially think it's some sort of joke or a test. Given their previous relationship in the original story, where Snape was often strict and not exactly friendly towards her, this sudden change would be quite a surprise. She might hesitate and not give an immediate answer, needing time to process this unexpected turn of events.
Snape would probably be quite surprised at first. Hermione is known for her academic prowess and self - sufficiency. His reaction could range from being dismissive, thinking she should be able to solve her own problems, to being intrigued by the nature of her request. If it's something related to the dark arts or a mystery in the wizarding world, his interest might be piqued, but he'd still be guarded in his response. He might even try to use her request as a way to gain some advantage or information for himself.
She might say yes right away. Hermione has deep feelings for Harry as a friend, and those could easily turn into romantic feelings. She would see all the good in Harry and believe that they could have a great relationship together.
Hermione might initially be very suspicious. Given her intelligence and wariness, she would not easily fall for the temptation. She would likely question Snape's motives and try to analyze the situation from all angles.
Another way it could develop is that it could create a rift among their friends. Some friends might support their relationship, while others, like those who have always shipped different pairings, could be against it. This could lead to some interesting plot twists and drama within the fanfiction story.
She would probably be very angry. Hermione is a strong - willed character. She might immediately try to break free from his grip and demand an explanation. For instance, she could shout at him, 'Professor Snape, what do you think you're doing? This is completely unacceptable!'
He could also be a bit sarcastic in his response. Snape has a sharp tongue, so he might say something like 'Miss Granger, what makes you think I have the time or inclination to help you?' But as Hermione explains her situation, he might gradually soften, realizing the seriousness of the matter. Maybe he starts to see a bit of himself in Hermione's thirst for knowledge.
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.
She might be initially defensive. Hermione is a proud and independent character. So, when Snape finds out about her arm, she could be worried that he'll use it against her in some way, like taking away house points or using it as an excuse to give her extra work.
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.
