It could mean that Percy, as a character or a person named Percy, has an interest in the fictional stories created by fans about Annabeth. Maybe he enjoys the different interpretations of Annabeth's character, relationships, or adventures in these fan - made stories.
Maybe they were just having a casual conversation about their interests in different fictional works related to their group. Since Percy is an important character in their story, Annabeth might have discovered some really well - written Percy fanfiction that she couldn't help but share her liking for with Thalia.
Maybe he likes it because he has a deep connection with Annabeth in the original story and the fanfic allows him to see different interpretations of their relationship.
It could be that Annabeth has a misunderstanding about Percy. She might think he's a threat to her position or status at the camp, so she bullies him to try and keep him in check.
It could be Chiron, the centaur. He's always keeping an eye on the campers and would likely be concerned if he caught them up to something. He might give them a stern talking - to and some extra chores as punishment.
Percy might be a bit flustered and embarrassed. He's protective of his relationship with Annabeth, so having Magnus walk in might make him feel like their privacy has been invaded. He could quickly try to shield Annabeth or just look really shocked.
Their shared experiences play a big role. They've been through so much together, like countless battles and adventures. Percy has seen Annabeth in tough situations and he knows how strong she is, but also how vulnerable. So he feels the need to protect her. For instance, they might have had a close call in a previous adventure where Annabeth was nearly killed, and that memory makes Percy extra vigilant.
Their relationship is likely to be complex. They are friends and comrades who have fought side by side many times. So, there's a strong bond of loyalty between them.
She might be a bit surprised at first. After all, fanfiction isn't always something they talk about. But then she could be interested and ask Annabeth more about it, like what kind of stories are in the fanfiction.
Misunderstandings about their future plans often lead to fights. Percy might want to focus on one type of adventure while Annabeth has other ideas. They argue about it, but in the end, the love between them overcomes the differences and they kiss. This shows how their relationship is complex and full of different opinions that need to be resolved.
