Well, it could symbolize their closeness. In many fanfics, when a character wears another's clothing, it shows a special bond. Maybe it represents protection, like Percy's jacket is a way for him to be there for Annabeth even when he's not physically around.
It can deepen their relationship. It shows that they are comfortable enough with each other to share personal items. This simple act can make their bond more visible to other characters and to the readers.
It could be a sign of closeness. Wearing his hoodie might show that Annabeth feels a special connection to Percy, like she wants to be close to him in a very personal way.
In the middle of a sudden cold spell at Camp Half - Blood, Annabeth was caught unprepared. Percy noticed her discomfort. He took his well - worn jacket, the one that smelled like the sea, and handed it to her. 'Here, take this,' he said. Annabeth blushed a bit as she put it on. It was big on her, but it was warm. This simple act made her heart flutter. They then went on to have a long conversation about their next adventure, with Annabeth now cozy in Percy's jacket.
Maybe it's a sign of closeness between them. In many relationships, sharing or wearing each other's clothes can show a deep bond. Annabeth might be cold and Percy's clothes are just there and convenient.
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.
It could be a sign of his protectiveness. Percy cares about Annabeth deeply, and the jacket is a physical way to shield her from the cold, just as he would shield her from danger in a more serious situation.
Percy might develop more of a steely determination. In Tartarus, he has to face extreme danger, which could make him even more resolute in protecting Annabeth and getting out. Annabeth, on the other hand, could become more resourceful. She'd have to use her wits in this strange and deadly place.
Annabeth might be initially speechless. She'd look at Percy with a mix of disbelief and love. After a moment, she would throw her arms around him and say 'yes' while laughing. She would then start thinking about all the adventures they could have as a married couple and how they could build a future together in both the mortal and demigod worlds.
Perhaps it's a symbol of their relationship within the fanfiction world. Wearing his hoodie might be her way of showing that she has a special bond with Percy. It could also be that she's cold and the hoodie is just conveniently there, but in the context of a fanfiction, it likely has a deeper meaning related to their relationship.
