In such a fanfic, it could be that Percy is betrayed because he represents a threat to the status quo. His growing power and influence might make others feel insecure. They might fear that he will change the way things are in their world. And since Annabeth is the only one who stands by him, it could be that she sees something in Percy that the others don't. Maybe she understands his true intentions better than anyone else, which is why she doesn't betray him.
One possible reason could be jealousy. Maybe Percy has some special abilities or achievements that make others envious. For example, his connection to the sea could be seen as a huge advantage that others might resent. Another reason could be misinformation. Someone might spread false rumors about Percy, leading others to believe he's done something wrong when he hasn't. It could also be that there's a misunderstanding about his relationship with Annabeth. Some might think he's getting special treatment from her or the other way around, which causes them to turn against him.
Perhaps it's because of some external influence. In the world of fanfics, there could be a powerful entity or force that wants to isolate Percy. This entity might manipulate the other characters into betraying him. Also, Percy's own hero complex could play a part. He might be so focused on doing the right thing that he accidentally steps on some toes. And his loyalty to Annabeth could be misconstrued as being part of a clique, causing others to feel left out and thus betray him.
One possible reason could be that Percy has unspoken feelings for Annabeth. He might be in love with her but not yet ready to admit it, so he just stares, trying to figure out his emotions.
Percy might initially feel a great deal of anger. He's been wronged by those he thought were his friends. But then, with Annabeth by his side, he could start to focus on finding out the truth. He might use his skills, like his combat abilities and strategic thinking, to figure out who or what is behind the betrayal.
One possible reason could be jealousy. Maybe she sees Percy getting more attention or praise than her in the fanfic world, and that envy turns into betrayal. Another reason might be a misunderstanding. For example, if there's some misinformation spread about Percy that makes Annabeth believe he's done something really bad.
Another possibility is that Percy made a really stupid mistake that endangered himself or others, and Annabeth, being the more level - headed one in some ways, slapped him to snap him out of his foolishness. For instance, if he rushed into a dangerous situation without a proper plan, Annabeth's slap could be a wake - up call.
One possible reason could be a misunderstanding. Maybe Percy did something that Annabeth misinterpreted, like making a decision during a quest without consulting her first, which made her feel disrespected.
It could be that she secretly likes the smell of it, which is a bit of a personal and intimate reason. In the context of the fanfic, it might also be a symbol of their relationship, and by stealing it, she's making a statement about how she feels towards him, whether she realizes it fully or not.
One reason could be jealousy. Maybe in the fanfic, Annabeth gets more attention or praise for her skills and Percy feels left out or overshadowed, which turns into hatred. Another possibility is that there's a rift caused by their different approaches to solving problems. If Annabeth's logical thinking clashes too much with Percy's more instinctive ways, it could lead to resentment.
Maybe she's jealous of Percy's popularity at school. It could be that he always gets more attention, whether it's from teachers or other students.
One possible reason could be a misunderstanding. Maybe Annabeth made a decision without consulting Percy, like choosing a quest that she knew was dangerous but didn't tell him until it was too late. Percy might feel left out and mad about it.
One possible reason could be a misunderstanding. Maybe Artemis misinterprets Percy's actions as a threat to her or her hunters. For example, if Percy accidentally endangers one of the hunters while trying to save someone else, Artemis might see it as a betrayal of her trust in him to respect her followers.
