The Slytherin students would be outraged. Snape is their head of house, and they would see Hermione's action as an attack on their house. This could lead to a lot of tension between the houses in Hogwarts. Meanwhile, some of the Gryffindor students might support Hermione, believing that she must have a good reason for her actions, while others would be more hesitant and wait for more information.
Ron would probably be more on Hermione's side at first. He trusts Hermione's judgment, but as the situation unfolds and more details come out, he might start to have doubts. The teachers, like Dumbledore, would approach the situation very carefully. Dumbledore would want to understand Hermione's motives and also Snape's side of the story before taking any major action.
Harry would be extremely shocked. He has always seen Snape as a complex figure, and Hermione capturing him would make him question a lot of things. He would likely try to get to the bottom of it and mediate between Hermione and Snape if possible.
Ron would probably be shocked. He always looks up to Hermione as the one who follows the rules. He might try to defend her at first, but then realize she was in the wrong. Harry, on the other hand, would be more understanding. He knows that sometimes there are more important things than just following the rules blindly.
Harry would probably be very confused at first. He knows Hermione is usually a rule - follower, so her wanting to be punished would seem out of the ordinary. He might try to talk her out of it, thinking there must be some misunderstanding. Ron, on the other hand, would be more straightforward. He'd likely say something like 'Hermione, you're mad!' and try to convince her that she doesn't deserve any punishment. The teachers, such as Professor McGonagall, would be taken aback as well. She would probably question Hermione carefully to understand her motives before deciding on any action.
Dumbledore would be a key figure in the reactions. If he believed in Snape's innocence, he would try to find a way to free Snape while also not alienating Harry. He might start his own investigation to uncover the truth. The other Hogwarts teachers would be in shock. Some might believe Harry is right, especially those who have always been a bit suspicious of Snape, while others would be outraged and demand an explanation from Harry.
Snape might initially be taken aback. He's used to students being intimidated by him, so Hermione's outburst could shock him into momentary silence. Then he might retaliate with his usual sarcasm, trying to put her in her place.
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.
Hermione would probably be shocked at first. She is a rational person, and this goes against the normal relationship dynamics she is used to. But then she might try to understand it from a logical perspective, thinking about how their relationship has developed over time. Ron, on the other hand, would likely be more vocal in his disbelief and might even make some jokes about it at first.
He might initially show annoyance. After all, Hermione is often seen as a know - it - all in his eyes. But his sense of justice and his underlying good nature (despite his cold exterior) would kick in. He'd untie her in a rather brusque manner, but then start to question her about how she got into this mess. Depending on her answer, he might offer some cryptic advice on how to avoid similar situations in the future.
Well, the other students in Gryffindor would likely be a bit taken aback at first. But then, knowing Hermione's intelligence and her tendency to be different, they would probably accept it. They might be curious about how she's going to manage to keep up the charade. The Hufflepuffs would be generally kind and understanding, perhaps even offering to help her if she needs it. The Ravenclaws would be intrigued by the idea and might study her transformation from a more academic perspective. The Slytherins, as a whole, would be more likely to try and use her disguise against her, either by blackmailing her or trying to expose her in a way that would cause her and her friends embarrassment.
The wizarding world would be in shock. Many would be outraged as Snape was a former Death Eater and Hermione was a beloved figure among the Order of the Phoenix. There would be a lot of rumors and gossip flying around. Some might even try to harm Hermione or Snape in their anger.
Hermione would probably be very confused at first. Snape has always been a rather intimidating and strict teacher, so his sudden change in behavior would be quite a shock. She might initially think it's some sort of trick or test.
