Harry might initially be confused. He has always looked up to Dumbledore, so when he realizes Dumbledore is trying to control him, he could start to question everything he thought he knew about their relationship. He may become more rebellious as a result, trying to break free from Dumbledore's influence and make his own decisions.
It could also be that Dumbledore has some secrets that he's afraid Hermione will uncover if she's left to her own devices. Hermione is known for her inquisitive nature. So, to keep these secrets hidden, he attempts to control her. For instance, if there are some hidden aspects of Hogwarts' history or certain faculty members that he doesn't want exposed, he might use control over Hermione to prevent her from delving too deep.
She would probably be defiant. Hermione is a strong - willed character. She values her independence and her ability to make her own decisions. So, she would likely question Dumbledore's motives and resist his control. For example, she might start her own investigations secretly to find out why Dumbledore is acting this way.
He might be motivated by a desire to protect Harry's reputation. Fanfiction can be full of wild and untrue stories, and Dumbledore doesn't want Harry to be misrepresented.
Well, he might face a lot of magical obstacles. Maybe there are spells protecting the fanfiction in some sort of enchanted library or digital realm. He'd have to use his vast magical knowledge to break through those barriers. And once he gets it, he could use it to better understand Harry's place in the wizarding world's public perception.
One possible scenario could be Ginny trying to control who Harry spends time with. For example, she might not like him being around Hermione so much because she's jealous. Another could be her trying to control Harry's actions in the wizarding world, like which quests or missions he undertakes. Maybe she thinks some are too dangerous and tries to stop him forcefully.
One key element could be the power dynamic between Molly and Harry. Maybe Molly has some reasons, like a motherly instinct, to try and control Harry's actions or decisions in the fanfiction world.
Well, in some fanfictions, Harry might initially be confused. He's used to Hermione being bossy but not this level of control. He could resist in a quiet way, like ignoring her suggestions more often.
