In a Harry Potter fanfiction where Dumbledore forgets who Harry is, what happens?

That would be a huge plot twist. It could throw the entire magical world into chaos and have a major impact on Harry's journey.

Well, it might have a significant impact on Harry's academic progress and his future. For instance, it could affect his magical abilities and career choices later on. Also, it could cause tension or changes in his relationships with teachers and classmates.

Hermione could be a main character. She might use her vast knowledge to help Harry and Dumbledore in their adventures. For example, she could research ancient spells or potions that are crucial for their mission.

For Harry, his friends like Ron and Hermione are likely to be his allies. They've always been by his side through thick and thin in the original series, so it's natural for them to support Harry in a confrontation with Dumbledore. Neville could also be an ally, given his growth and courage shown in the books.

One possible reason could be that Harry breaks school rules in the fanfiction. For example, if he ventures into the Forbidden Forest without permission. Dumbledore is strict about the safety of students and such disobedience might lead to punishment.

Well, it might be a fanfic where a new dark wizard emerges with a unique power to manipulate memories, and they target Dumbledore's memories of Harry Potter. Or it could be a story where Dumbledore gets caught in a complex web of magical experiments gone awry, leading to this memory loss.

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.

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.

Ron could also be there. He might be a bit jealous at first of Harry's special relationship with Dumbledore but then comes around and supports Harry in his adventures as an apprentice. There could be some great scenes of their friendship evolving in this new context.
