Hermione would probably be a bit worried at first. She's always been one to follow the rules, but she also supports Harry. So she might try to convince him to find a more diplomatic way to handle it. Ron, on the other hand, would be more on Harry's side right away. He'd say something like 'Good for you, Harry!' The teachers would be shocked. Snape would be furious and might try to give him an even harsher punishment, while McGonagall might be more understanding and listen to Harry's reasons.
The Weasley twins would likely be very excited. They've always been ones to bend and break the rules themselves, so they would probably see Harry as a kindred spirit. They might even offer to help Harry get out of the situation, perhaps by creating some sort of distraction. As for the rest of the Hogwarts staff, Filch would be outraged. He loves giving out detentions and seeing someone refuse would be like a personal insult to him. However, some of the more progressive teachers might start to question the fairness of the detention system as a whole because of Harry's refusal.
One possibility is that Harry stands up against an unfair detention. Maybe he has evidence that he was wrongly accused of something, like when Snape tries to give him detention unjustly. So he refuses and decides to take his case to Dumbledore, who then investigates and clears Harry's name.
Well, in fanfiction, Harry's refusal of detention could be a major turning point. It might lead to him exploring other ways to solve the problems that led to the detention in the first place. Maybe he discovers a new magic or finds an ally who helps him deal with the underlying issues. But on the other hand, it could also put him at odds with Hogwarts' traditional ways. The teachers would be forced to re - evaluate their discipline methods, and Harry would have to deal with the fallout, which could include being ostracized by some or having to prove his point in a very difficult situation.
Harry would probably be quite resentful at first. He might think Snape is just being his usual unfair self. So, he would be sulky and do the tasks reluctantly.
Hermione would be extremely shocked and disappointed. She has always been a firm believer in the fight against Voldemort and would see Harry's alliance as a huge betrayal. She would probably try to talk Harry out of it at first and if that fails, she might start her own investigation to find out what made Harry do this.
When Harry Potter refuses detention in fanfiction, the plot may develop in a way that Harry starts to question the entire Hogwarts disciplinary system. He could form a group of like - minded students who also have issues with the way detentions are given. This group might then try to change the system from within. Meanwhile, the faculty would be in an uproar, with some teachers seeing Harry as a troublemaker and others perhaps secretly admiring his courage. The story could then focus on the power struggle between the students and the teachers over the detention system.
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.
The other students at Hogwarts would be very afraid. Some might avoid Harry out of fear that Voldemort could use him to harm them. But Neville, being brave, would probably try to reach out to Harry in some way, believing that there's still good in him. The Order of the Phoenix would be in chaos at first. But then they'd start formulating plans. Lupin would be worried but also think rationally about how to deal with the situation, using his experience as a werewolf and a wizard.
Well, some of their friends might be really excited for them. Hazel would see it as a positive development, thinking that they are a great couple. Frank might be a bit shy about the whole thing, but still give them his祝福 (blessing). However, there could also be some friends who are a bit concerned. Thalia, for example, might worry that their relationship could get in the way of their demigod duties. She would be afraid that they would be too focused on each other and not on the important tasks at hand. But overall, most of their friends would probably adjust to the new relationship fairly quickly.
At first, Harry might be extremely confused. He trusts Sirius to a certain extent, but being kidnapped is still a shock. He would probably ask Sirius a lot of questions like 'Why are you doing this?' and 'Where are we going?'
The common folk in Skyrim would probably be a bit scared at first. Harry's strange clothes and the fact that he can do magic so effortlessly would be quite intimidating. But if he helps them out, like getting rid of a bandit problem or curing a disease, they would soon start to accept and even revere him as a powerful hero.
