Some fanfictions might be trying to add drama by creating conflict between Annabeth and Percy. The writer may not handle it well, making Annabeth's dislike for Percy seem forced and out of character. This can happen when the writer focuses more on creating shock value rather than staying true to the essence of the characters.
Maybe in some fanfictions, the writers change the characters' personalities too much. Annabeth is a strong - willed character, and if Percy is portrayed in a way that goes against their original relationship dynamic, she might seem to 'hate' him in that fictional context.
It could be that the fanfiction plots are so convoluted. For example, the writer might create some really out - of - character situations for Percy and Annabeth. If Percy is constantly put in scenarios where he's made to be at odds with Annabeth in ways that don't feel true to the original series, it could give the impression that he hates her in the fanfiction.
Maybe in some fanfics, the author wants to create a new and controversial plot. They might make Percy hate Annabeth due to some misunderstandings, like a miscommunication about a quest or Percy believing Annabeth has betrayed him in some way.
Perhaps in this high school fanfiction setting, Percy has a different group of friends who don't like Annabeth. Their influence on Percy gradually makes him develop a dislike for her. You know, peer pressure can sometimes change a person's attitude towards others.
It could be that the way the child is written in the fanfiction goes against Annabeth's character. For example, if the child is depicted as being overly needy or bratty and Annabeth, who values independence and order, just can't stand it. Also, it might be that the existence of the child changes Percy in a way that Annabeth doesn't like. Like Percy starts to neglect her in favor of the child.
Perhaps Annabeth's dad has some old - fashioned ideas. He might believe that Percy doesn't have the right qualities to be with his daughter. He could also be jealous in a way. Percy is an important person in Annabeth's life and her dad might feel left out or that Percy is taking his place in a sense.
Maybe they have a different taste in literature. They might prefer other types of stories and not be into the fanfiction genre, especially those related to Percy and Annabeth.
It could be that Percy's arrival disrupts the balance or routine at camp, which Annabeth doesn't like. Or perhaps there's some jealousy or competition involved.
Well, perhaps in fanfiction, their characters are often misrepresented. Maybe Percy's personality traits are distorted in a way that makes him seem out of character when paired with Jason, which could lead to Percy seeming to 'hate' Jason in those stories.
Maybe Frederick has a different view of the original work and thinks fanfiction distorts it. For example, if he is a purist who loves the original Percy story as it is, any fan - made alterations in the fanfiction might be off - putting to him.
Well, it could be that in the fanfiction, Zeus's actions towards Percy's friends or family were not good. For example, if Zeus endangered them or was overly harsh. Percy is a character who values loyalty and justice, so he would hate Zeus for acting against those values.
