In this kind of fanfiction, it could be that Dumbledore has some very complex motives for 'kidnapping' Harry. Maybe he wants to protect Harry from a danger that he can't explain openly. For example, there might be a powerful dark wizard who has found a way to spy on Hogwarts and Dumbledore believes that keeping Harry in a secret location is the only way to keep him safe.
Another aspect could be that Dumbledore is being controlled or influenced by some external force. In the fanfiction, this could lead to a very interesting story where Harry has to figure out how to break Dumbledore free from this control while also escaping from his 'kidnapper'. It would be a total role - reversal from the original story.
Well, perhaps Dumbledore has some dark secret and believes Harry is the key to it. He might kidnap Harry to keep him away from Voldemort in a very unorthodox way. Maybe he wants to train Harry in isolation for some super - powerful magic that he doesn't want Voldemort to find out about.
There could be. Fanfiction writers love to explore different scenarios that deviate from the original story. But it's important to note that this goes against the general perception of Dumbledore's character. In the official Harry Potter series, Dumbledore is a protector, not a kidnapper. But in the world of fanfiction, anything is possible.
At first, Harry may be in shock. He's been taken by someone he respects and looks up to. As he comes to terms with his situation, he might try to reason with Dumbledore. If that doesn't work, he could start to plan an escape, using his wits and the magic he knows. He might also feel angry that Dumbledore is treating him this way when he's always been on Harry's side, or at least that's what Harry thought.
Well, in certain Harry Potter fanfiction, Dumbledore can come across as insane. It really depends on the writer's interpretation and the direction they want to take the story. Some might do it for shock value, to create a more edgy or different take on the well - known character. However, the canonical Dumbledore was a highly intelligent and calculating figure, not insane.
Hermione would be extremely worried and would start researching like crazy to find out where Dumbledore has taken Harry. She would probably suspect that something is not right with Dumbledore and would try to convince Ron to help her. Ron, on the other hand, would be initially shocked but then would be ready to go on a rescue mission with Hermione.
At first, Harry would be in shock. He would be full of disbelief that Dumbledore, of all people, would do such a thing. He would struggle both physically and emotionally. Physically, he would try to break free from whatever bindings or magical restraints Dumbledore has put on him. Emotionally, he would be a mess, feeling hurt, scared, and confused. However, depending on how the story unfolds, he could gradually come to terms with the situation if Dumbledore manages to convince him that it's all for a greater good.
Well, Harry might outsmart Dumbledore by using his unique understanding of the magical world in ways Dumbledore doesn't expect. For example, Harry has a more direct experience with some dark magic items due to his encounters with Voldemort. He could use this knowledge to make decisions that seem counter - intuitive to Dumbledore but are actually more effective in a particular situation.
He might give Harry detention. Harry could be made to clean the trophies in the trophy room or help Hagrid with some difficult tasks in the Forbidden Forest under strict supervision.
