Perhaps it's a job that involves leading a team to preserve and study some of the most mysterious and important ancient ruins. Annabeth's love for knowledge and architecture combined with the leadership aspect of the job could be very appealing. She might think that this job is a crucial step in her career and something she can't pass up, even if it means leaving Percy.
Another possibility is that there could be external forces at play. In some fanfic storylines, there might be a prophecy or a powerful enemy that convinces Annabeth that leaving Percy is the only way to protect him. She might sacrifice their relationship for his safety, believing that her presence endangers him in some way.
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.
Well, Percy could have a range of reactions. At first, he might be in denial, not believing that Annabeth would actually leave him for a job. Then, as it sinks in, he could get angry. He's a passionate guy, and this would be a big blow to him. He might also feel a bit of envy towards the job that seems to have taken Annabeth away from him. In the long run, though, he could use this as a chance to grow on his own and become more independent.
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.
She might like the ones that focus on their romantic relationship. Since they have a strong connection in the original story, fanfictions that explore their love in different ways could be appealing to her.
Well, one possible reason could be that Percy made a really stupid decision without consulting Annabeth first. Like, if he went off on a dangerous mission on his own when they were supposed to be a team. Annabeth is a very strategic person and she might feel betrayed or extremely frustrated by such actions.
It could also be due to some sort of magic or mind - control. A powerful enemy might have cast a spell on Annabeth, forcing her to turn against Percy. In this case, it's not really her own will but the result of external manipulation.
She'd probably be shocked at first. But then her face would light up with joy. After all, she and Percy have been through so much together.
For a boy, they could go with Orion, a name associated with a great hunter in Greek mythology. It would symbolize strength and skill. And for a girl, they might name her Calypso, not just because it's a beautiful name, but also as a way to remember the different characters they've encountered on their adventures and the lessons learned from them.
Their unique relationship. Percy is a son of Poseidon, brave and impulsive, while Annabeth is a daughter of Athena, intelligent and strategic. The contrast and the way they complement each other in the original stories make their relationship ripe for exploration in fanfiction. Writers can create different scenarios for them, like facing new monsters or dealing with relationship problems.
