One possible plotline could be a misunderstanding. Maybe Annabeth is seen spending a lot of time with Nico because he needs her help with something, like understanding some ancient prophecy. Percy misinterprets this as something more and there is a rift in their relationship that they have to work through.
I'm not entirely sure. While fanfic communities have a wide range of content, it can be hard to find one that specifically meets this criteria. However, there could be some out there that handle the situation in a more family - friendly way, perhaps emphasizing friendship and misunderstandings rather than actual cheating in a more adult sense.
This type of fanfiction is a bit of a tricky one. On one hand, it's a form of creative expression. Writers might be exploring complex emotions and relationship breakdowns. But it's also a departure from the core values of the original story. The relationship between Percy and Annabeth is a central and positive aspect of the source material. So when fanfiction changes that so drastically, it can make many fans uncomfortable. It's important to remember that fanfiction exists in a realm of its own, but it still has an impact on how fans perceive the original characters and relationships.
A possible non - adult - themed plot could be that Ginny is trying to help Oliver with some personal issues he's having. She's being a good friend, but rumors start spreading in Hogwarts that she's cheating on Harry. Harry initially believes the rumors, but as he investigates further, he realizes that Ginny was just being kind. This leads to a story about friendship, love, and not believing everything you hear.
In most fanfics, this is often just a fictional and sometimes out - of - character plot device. There's no real evidence within the official Percy Jackson canon for such a thing, but in fan - created stories, it could be based on the author's desire to create drama. However, it goes against the core relationship we know from the original books.
One possible plotline could be a magical experiment gone wrong. Maybe they were working on a spell to enhance fertility in magical creatures, but something backfired and Hermione ended up with some symptoms that made it seem like she was pregnant. Harry and Hermione then have to find a way to reverse the spell without anyone else finding out, leading to a lot of sneaking around and problem - solving.
One common theme is friendship. Their bond is often explored, like how they support and trust each other. Another theme is adventure. They are usually sent on quests or face challenges together. For example, in many fanfics they have to battle mythical creatures.
In the original context, Annabeth is a character with integrity and Percy's beloved partner. But in this fanfiction, her image is severely tarnished as she cheats on Percy. This completely alters the way fans might view her. As for Nico, he was already a somewhat mysterious and complex character. This fanfiction further complicates his character by making him part of such a controversial relationship. Overall, it can make the characters seem less like the ones fans know and love from the official story, and more like tools for a rather unorthodox plot device.
Another plotline could be that they are babysitting a group of demigod toddlers at Camp Half - Blood. The toddlers keep getting into mischief, like stealing nectar and ambrosia. Percy and Annabeth have to keep them in line, teach them about the rules, and also make sure they don't accidentally harm themselves with their budding powers. It could be a really cute and chaotic story.
One possible plotline could be that they are on a dangerous mission, and a magical mishap causes this situation. Then they have to deal with the social and family reactions in the wizarding world, which could be full of prejudice and confusion. Another could be that it's a result of a new, experimental magic they were trying out for a good cause, and now they have to figure out how to move forward with their friendship and their responsibilities.
A possible plotline could be that Beck is blackmailed into faking a relationship with someone else, which Jade misinterprets as cheating. He's too afraid to tell Jade the truth at first because of the blackmailer's threats. As the story progresses, Beck realizes he has to come clean and fight for his relationship with Jade. Another plot could involve Beck losing his memory briefly and getting involved with someone else during that time, not realizing he has a relationship with Jade, and then the process of him regaining his memory and trying to make things right with Jade.
