Percy would be extremely guilt - ridden. He would feel that it should have been him who got hurt instead of Annabeth. He might also be filled with a sense of self - loathing for not being able to protect her.
Perhaps they are in a maze or a dangerous place filled with traps. Percy accidentally triggers a trap that releases a knife - like projectile and Annabeth, seeing the danger to Percy, moves quickly to shield him from it. This would show her deep loyalty and love for Percy.
One possible scenario could be that Percy got injured and Annabeth needs to tend to his wounds on his torso, so she takes his shirt off. For example, he might have been scratched by a monster during a battle, and she has to clean and bandage the wound quickly.
Annabeth is known for her intelligence and strategic thinking. She is a strong and independent character. Percy, on the other hand, is brave and has a strong connection to the water due to his father being Poseidon. In the fanfic, when Annabeth sits in Percy's lap, it might be a way to show their unique relationship which has developed over the course of their many shared experiences in the Percy Jackson universe.
Love and loyalty are common themes. Annabeth's care for Percy often stems from her deep love for him. It shows that no matter what, she'll be there for him.
No, it's not appropriate. Fanfiction should generally uphold moral and ethical standards. Writing about such intimate and private aspects in a sexual context is disrespectful to the characters and can make many readers uncomfortable.
Maybe it's about Annabeth taking Percy's hoodie as a sign of closeness. She might wear it around and it makes Percy feel a certain way, like a mix of surprise and a bit of flattery.
There is also 'Annabeth's Vigil'. In this fanfiction, Annabeth stays by Percy's side when he's injured and in a coma. She reads to him, talks to him, and basically does everything she can to keep his spirits up and help him heal. It's a really heartwarming story that delves deep into their relationship.
In Percy Jackson and Annabeth fanfics, the relationship between them can be developed in various ways. Some might show their daily life at Camp Half - Blood in more detail, with little arguments and sweet reconciliations. Others could take them on a quest that's not in the official series, adding new monsters and challenges for them to overcome.
In many fanfic stories, Percy and Annabeth often face various enemies. Some common ones might be new monsters created by the author, or perhaps other demigods who have turned to the dark side. These enemies add drama and action to the stories.
