The change in their relationship would be quite complex. Harry's rejection could cause Dumbledore to become more secretive in an attempt to protect his plans or reputation. Harry, in turn, would start to distance himself from Dumbledore. This could lead to a rift in the entire wizarding community as they are two very important figures. Some might side with Harry, believing in his reasons for rejection, while others would stick with Dumbledore, thinking he still has the best interests of the wizarding world at heart. Their relationship would no longer be the guiding force it once was in the fight against evil.
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.
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.
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.
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.
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.
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.
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.
Well, it could be that Harry has a different view on how to handle the war against Voldemort. Dumbledore is often very strategic and sometimes keeps things from Harry for what he believes is the greater good. But Harry might think that full transparency is necessary. Also, Harry may have formed new alliances or friendships that give him different perspectives, and these new ideas conflict with Dumbledore's. He might feel that Dumbledore's approach is too old - fashioned or risky in a new context.
It might make Harry more confident. With Dumbledore's training, Harry gains more knowledge and skills, which gives him the confidence to face challenges.
It could create a rift. Harry might feel betrayed or not understood by Dumbledore. If Harry is starting to explore his own identity and Dumbledore is against it, Harry would likely be hurt and this could lead to a strained relationship. He might start to question Dumbledore's wisdom and guidance that he has always relied on.
He becomes more nurturing. Dumbledore, who was mainly seen as a wise leader, now has to be a caregiver. He might show more patience and tenderness as he takes on the role of a father to Harry.
