Ron might be more divided. On one hand, he trusts Harry and would understand if Harry has his reasons. But on the other hand, Dumbledore has always been a figure of great respect. So Ron would be in a difficult position. He might try to be a mediator between Harry and those who still support Dumbledore. This would change the dynamic of their friendship a bit as he has to take a more neutral stance.
The relationship between Harry and the other members of the Order of Phoenix would also be strained. They are all used to following Dumbledore's lead and Harry's refusal might seem like a betrayal to some of them. They might start to question Harry's loyalty and motives, which could lead to a split within the group.
Well, it could make Hermione very worried. Since she's usually the one who supports Harry and tries to keep him on the right path. If Harry refuses to help Dumbledore, Hermione might try to persuade him. This could create some tension between them if Harry is stubborn. For example, she might think Harry is being selfish or short - sighted.
Among the students, Harry's action would make him a very polarizing figure. Some students would see him as a hero for taking a stand against the all - powerful Dumbledore, while others would view him as a troublemaker. This would completely change the social dynamics within the school. The younger students might look up to him with a mix of awe and fear, while the older students might be more critical of his actions.
The power dynamic also shifts. Usually, Dumbledore is seen as a mentor and a figure of authority. But when Harry denounces him, Harry is challenging that authority. In some fanfic, this could lead to a power struggle within the wizarding community as others take sides. It can also cause Harry to seek new allies who share his view of Dumbledore, changing the social fabric of the story.
The relationship would become very strained. Harry's rejection would likely make Dumbledore re - evaluate his actions and how he has interacted with Harry. Dumbledore might be shocked at first, since he probably thought Harry was on the same page as him most of the time.
In the wider wizarding world, it could make Harry a controversial figure. Some might see him as a rebel who is undermining the great Albus Dumbledore. Others, especially those who have had doubts about Dumbledore's secrecy, might start to view Harry as a brave truth - seeker. This would change how various wizarding families and factions interact with Harry, either distancing themselves or becoming more interested in his cause.
Well, it might make Harry more isolated. In the original story, Dumbledore was like a guiding figure for Harry. If Harry doesn't trust him in the fanfic, he may not trust the advice Dumbledore gives about other characters either. So he might be more cautious around people Dumbledore was friendly with, like Hagrid. He might think they are also in on Dumbledore's secrets and not be as open with them.
The relationship turns into one of opposition in some fanfics. Harry, now independent, may be working towards goals that Dumbledore doesn't approve of. Dumbledore may see Harry as a loose cannon and try to control him from a distance, while Harry resents any such attempts. Their interactions become tense and full of unspoken accusations.
It changes Harry's view of Snape completely. Harry already had a very complex relationship with Snape, but this act would make him see Snape as an even greater enemy. He would be filled with rage and a thirst for revenge. Hermione and Ron would also be very affected. They would support Harry in his quest to avenge Dumbledore and would see Snape as a traitor to the wizarding world.
The fanfiction might show a more adversarial relationship. Harry could start to oppose Dumbledore's plans instead of following them blindly. This is very different from the original where Harry was mostly compliant. For example, in the original, Harry accepted Dumbledore's tasks like finding the Horcruxes, but in the fanfiction, he might question the motives behind these tasks and resist them.
As the story progresses, Dumbledore might try to make amends. He could start revealing some of his secrets to Harry in an attempt to regain his trust. Harry, on the other hand, would be hesitant at first but gradually start to listen and understand Dumbledore's reasons.
Well, it could show that their relationship was based on false pretenses. Harry might find out that Dumbledore had ulterior motives for taking him under his wing. In the fanfiction, this would completely change the dynamic. Instead of the warm, if somewhat distant, relationship in the books, it could be a relationship where Harry feels used and deceived. This new view of the relationship would likely drive Harry to break away from Dumbledore's influence and forge his own path more determinedly.
