His friends might be divided in their opinions. Some of them might still trust Dumbledore wholeheartedly and think Harry is overreacting. This could lead to arguments and a strain in their relationships.
On the other hand, some friends could side with Harry. They might start to question Dumbledore too, and together they might form a sort of 'anti - Dumbledore' group within Hogwarts. This would change the dynamics of their friendship as they are now united against a common 'enemy' in Dumbledore.
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.
McGonagall might notice Harry's distrust and feel hurt or frustrated. She may try to figure out what went wrong but find it difficult as Harry is not forthcoming. Their interactions become less warm and more formal. For example, in class, Harry may be less likely to ask for help from McGonagall, and McGonagall may be more strict with Harry as she doesn't understand his change in attitude.
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.
Well, in some fanfictions, Harry might not trust Dumbledore because Dumbledore often keeps secrets. For example, he doesn't fully disclose the prophecy details at once. Harry could feel like he's being manipulated or not given all the information he needs to face the challenges. So, that lack of transparency can lead to Harry's distrust.
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.
In some fanfiction, Harry might not trust Dumbledore because the author wants to explore different power dynamics. Maybe they show Dumbledore keeping too many secrets, like about Harry's past or the true nature of the threats he faces. This secrecy can make Harry feel manipulated and thus lead to a lack of trust.
One possible reason could be that Harry discovers some hidden actions of Dumbledore that seem manipulative. For example, if Dumbledore has been keeping secrets about Harry's past or his destiny without fully explaining them. Harry might feel used or deceived, leading to his distrust.
His friends might be initially divided. Some may be more loyal to Dumbledore's ideas and methods and might not understand Harry's decision right away. For example, Hermione, who often respects authority and tradition, could struggle with Harry's choice.
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 dynamic becomes very strained. Harry's lack of trust in Ron means that their usual banter and easy camaraderie is gone. Hermione will be stressed because she values both of their friendships. She may end up spending more time with Harry to try to help him through his doubts, which could make Ron jealous. Ron, on the other hand, might become defensive and start acting out, which only makes Harry trust him less. This could lead to a cycle of misunderstandings and a breakdown of their friendship triangle.
