It might be that a dark magic artifact wiped out his memories. Or maybe a forgotten enchantment from his past has resurfaced to cause this memory loss.
Perhaps Harry suffered a trauma or injury that affected his memory. Or it might be part of a complex magical experiment gone wrong.
Another possible betrayer could be Dumbledore in some darker fanfictions. He might have a hidden agenda all along. He could be using Harry as a pawn in a much larger and more sinister game. And when Harry starts to figure things out and goes against Dumbledore's plans, Dumbledore betrays him to keep his own plans on track.
It could be that the fanfiction explores alternate universes or scenarios where Harry's development takes an unexpected turn. Maybe he has new powers or makes choices that are out of the ordinary.
It might be that Harry Potter values the authenticity of their story. Fanfiction can be all over the place with different plotlines and characterizations. He may feel that the fan - made stories about Hermione don't do justice to their real - life (in the wizarding world) experiences together. He's used to their real interactions and growth, and fanfiction might seem like a strange and wrong version of that to him.
Hogwarts is a well - established and copyrighted world within the official Harry Potter series. Fanfiction often takes creative liberties that might not align with the original concept of Hogwarts as envisioned by J.K. Rowling. So, it's not a proper place for fanfiction in a legal and purist sense.
Well, it could be that the authors of fanfiction want to explore different aspects of the Harry Potter universe other than fighting. Maybe they're more interested in the relationships between characters or the daily life at Hogwarts.
Well, Harry Potter is a character in the original story. Fanfiction often takes the original story in all kinds of wild and different directions. Harry, being from the original, proper story, may not be able to understand these new and sometimes out - of - the - box interpretations that fanfiction presents. It's like he's from a very specific world, and fanfiction creates a whole bunch of new worlds based on that, which he has no knowledge of.
Maybe he's looking for inspiration. The rich world of Harry Potter can spark all kinds of creative ideas, and fanfiction can be a great source of inspiration for his own writing or just for daydreaming about the wizarding world.
Yes, in some fanfictions, Harry Potter discovers that his identity is more complex than he originally thought.
Maybe it's just never been something he's had the chance to learn. Or it could be part of the plot to create some challenges for him.
It could be that in this fanfiction, Harry was raised in an environment where reading wasn't emphasized or accessible. Or perhaps he had a traumatic experience that made it difficult for him to learn to read.
