Another possibility is a miscommunication or false accusation within the fanfiction world. Someone could spread lies about Harry among the Weasleys, leading them to believe he has done something terrible and thus turning against him. But this is a far cry from the deep bond they share in the official 'Harry Potter' story.
In some fanfictions, Harry could be betrayed by friends due to jealousy. For example, if a friend is jealous of Harry's fame as the 'Chosen One'. Another reason might be a misunderstanding. Maybe Harry is wrongly suspected of using dark magic, and his friends, without proper investigation, turn against him.
In certain fanfictions, Dumbledore's secrets are the root of the perceived betrayal. For instance, his secrets about the Deathly Hallows. If Harry discovers that Dumbledore had known more about the Hallows all along and didn't share this knowledge, which could have changed Harry's journey and decisions, it could be written as a betrayal. Harry may feel that he was used and misled by Dumbledore, and thus the idea of betrayal emerges in these fan - created stories.
Well, in some fanfictions, it could be that the Weasleys betray Harry because of Voldemort's influence. Maybe they are Imperiused to turn against him.
In some fanfictions, Hermione might betray Harry due to a misunderstanding. For example, if there were false rumors spread about Harry being involved in dark magic or having a secret, evil plan. Hermione, being a stickler for the rules and the greater good in the original series, might be misled into believing these rumors and thus betray Harry.
A plot could involve a family secret. Maybe the Weasleys discover that Harry has some connection to an event in their past that they wrongly interpret as harmful, and this leads to their betrayal. For example, if they think Harry is related to someone who caused harm to their family long ago, even though it's a false connection.
Love could also play a role. Maybe one of the Weasleys falls in love with someone who has a vendetta against Harry. To please their love interest, they could end up betraying Harry. It's a more emotional and complex reason compared to the others, but it can add depth to the fanfiction story.
In this fanfiction, the betrayal might also stem from jealousy. Harry is often in the spotlight, and the Weasleys, who have always been a big family but not always in the center of attention, could let envy get the better of them. This could lead to actions that Harry perceives as betrayal, like spreading rumors or withholding support when he needs it most.
Well, it could be quite interesting. They might find some of the creative interpretations amusing. For example, they could laugh at how some fanfictions exaggerate the magical abilities of the characters. They might also be a bit shocked if the fanfictions deviate too much from the 'true' story they know.
Well, it could be that in these fanfictions, a dark influence overcomes Hermione and Ron. They might be manipulated by a powerful dark wizard who makes them believe that betraying Harry is the right thing to do. It could also be a miscommunication situation where they think they are helping but end up betraying Harry. For instance, they might be tricked into believing that Harry has turned bad and needs to be stopped.
Well, often in these fanfictions, if a Weasley is under Imperio, it can lead to a lot of drama. Let's say Ron is under Imperio. It could create a rift between him and Harry. The other Weasleys would then be on a mission to break the curse. Fanfiction writers might explore how the Weasley family dynamics change under such a dark spell. They might also show how different Weasleys react to the situation. Some might be more impulsive in trying to rescue the cursed one, while others might be more cautious and methodical.
