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 Harry is a pacifist in this fanfic. He could have moral objections to fighting, believing that there are better ways to resolve conflicts, such as through dialogue or negotiation.
It could be that in the fanfiction, a dark wizard has somehow influenced the Weasleys' actions without their knowledge. Harry, being cautious after all his experiences with the dark side, might misinterpret these changes in their behavior as signs of untrustworthiness. So he doesn't trust them until he figures out what's really going on.
Harry Potter has lived through his own real experiences in the wizarding world. Fanfiction is often just the creative interpretations of fans. It could distort the true nature of his relationships, the events he's been through, and the values of the wizarding world. So, he doesn't blindly trust it. For example, some fanfiction might change the way his friendships are portrayed, which doesn't align with his real experiences.
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 possibility could be that Harry and Voldemort reach a truce through some magical means. Maybe a powerful magic spell binds them to peace. Another scenario might be that other characters step in to prevent the fight. For example, Dumbledore could use his great power and influence to stop the conflict from happening.
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.
Hermione could be the main character. She is extremely intelligent and powerful in her own right. She might use her vast knowledge of magic to find a solution that doesn't involve Harry fighting Voldemort. For example, she could discover a way to rewrite the rules of magic that govern Voldemort's power.
