Well, in such a fanfiction scenario, perhaps Annabeth betrays Percy because of some external influence like a powerful enemy who has blackmailed her. Percy would then be left with a mix of emotions - anger, confusion, and sadness. His adventures would take a different turn as he has to deal with this new situation instead of relying on Annabeth as he used to.
One possibility is that it could lead to Percy's downfall. If Annabeth, who has been his close ally and friend, betrays him, it might shatter his trust not only in her but also in others. He could become more isolated and vulnerable, making it easier for his enemies to target him.
It could be for the greater good as she perceives it. Annabeth might think that by betraying Percy, she can save more people or prevent a greater disaster. However, her perception might be wrong, and she realizes it too late after the betrayal has already occurred.
Well, it could be that Annabeth and Percy meet in a different setting than in the original stories. For example, they could meet in a modern city but still have to deal with their demigod issues. They might discover new powers or abilities within themselves as they interact. And there could be some romantic moments as their relationship often has that element in fanfictions.
Then, she would probably be angry. Annabeth is a strong - willed character. She would feel betrayed and used, and her anger would fuel her to find out the truth. She might start her own investigation to figure out what's really going on with Percy, whether he's been influenced by someone or if there's another reason for his actions.
One possible reason could be that Kronos has somehow tricked her. Maybe he promised her something she desperately wanted, like power to protect her loved ones in a way she thought Percy couldn't. Another reason might be that she was brainwashed. Kronos could have used some dark magic or manipulation to make her believe that Percy was on the wrong side.
In this kind of fanfiction, they might have an adventure together. Maybe they'll face a new monster that they haven't encountered before. For example, a mythical creature from a less - known part of Greek mythology.
Well, it could be that in the fanfiction, the writer might have developed Annabeth's character in a way where she becomes disillusioned with Percy. Maybe she sees Luke as having something that Percy lacks, like a different kind of power or charm. Or perhaps there are some misunderstandings between Percy and Annabeth that Luke takes advantage of, pushing Annabeth towards the betrayal.
Well, perhaps in the fanfiction, they initially feel a bit awkward sharing the bed. But as the night progresses, they find comfort in each other's presence. Percy might crack a joke or two to ease the tension, and Annabeth would roll her eyes at him in that affectionate way she does. They could end up falling asleep while holding hands, symbolizing their strong bond.
Well, perhaps Percy plans this elaborate scheme to ask Annabeth out. He might enlist the help of their friends, like Grover. Grover could set up a picnic in a beautiful meadow. Percy then shows up with a bouquet of Annabeth's favorite flowers and asks her out. She would be touched by the effort he put in and say yes. Then they start planning all the things they want to do together on their first official date.
One possibility is that the Greek class is a place for Percy and Annabeth to show their relationship development. They could be paired up for a project on a particular Greek hero. While working together, they start to understand each other better. Annabeth might be really into the research part, while Percy brings in his practical understanding of how the hero's traits could be applied in a real - life - or rather, demigod - life - situation. And through this, their bond deepens as they both contribute their unique perspectives.
Maybe in 'Annabeth meets famous Percy fanfiction', the famous Percy fan could be from another dimension or time. Annabeth would be really confused at first. But as they interact, they might find out that they both have unique insights into Percy. They could end up teaming up to face some new threat in the world of fanfiction that is related to Percy's story, like a new monster that is attracted to the idea of Percy's fame within this fan - created world.
