Well, it could start with Annabeth being targeted by a powerful sorcerer who wants to use her knowledge for his own evil purposes. Percy, being her bodyguard, has to navigate through various magical traps and illusions while also trying to keep Annabeth's spirits up. They might also have some heart - to - heart conversations during their adventures, which would develop their relationship further.
One interesting plotline could be Percy having to protect a high - profile celebrity from a mysterious and dangerous stalker. He uses his unique skills and knowledge to outwit the stalker at every turn.
One possible plotline could be their adventures in a new, undiscovered part of the mythological world. Maybe they stumble upon a hidden realm full of ancient and powerful creatures that they have to either befriend or fight.
A really interesting plotline could be them going on a quest together as a couple. They'd have to rely on each other's strengths more than ever. Percy's water - related powers and Annabeth's strategic thinking would be put to the test. Along the way, they could discover new things about each other and their relationship could deepen.
Another plotline could be centered around Annabeth's jealousy when other characters show interest in Percy. So she's constantly thinking about Percy and how much she wants him all to herself. Her 'drooling' over him is a sign of her deep - seated feelings that she might not fully express outwardly all the time.
Well, perhaps in the fanfiction, Annabeth betrays Percy's trust in a relationship way. She could start seeing someone else and use Percy's secrets against him to make herself look better in front of the new person. Or she might side with a group that Percy is against, believing their lies and false promises over Percy's warnings. This could lead to Percy feeling completely alone and having to find new allies.
Another plotline could be that they are babysitting a group of demigod toddlers at Camp Half - Blood. The toddlers keep getting into mischief, like stealing nectar and ambrosia. Percy and Annabeth have to keep them in line, teach them about the rules, and also make sure they don't accidentally harm themselves with their budding powers. It could be a really cute and chaotic story.
One possible plotline could be Percy going on a desperate search for Annabeth. He might start by retracing her last known steps, asking all their mutual friends and allies if they've seen her. Another could be Percy having to face some old enemies alone in his search, as Annabeth was usually the one who strategized with him. And he could also discover some hidden secrets about Annabeth's past during the search that he never knew before.
One possible plotline could be that a new villain, who has powers of hypnosis, targets Annabeth because of her strategic mind. The villain wants to use her knowledge of Camp Half - Blood and the demigod world to their advantage. Percy and the others then have to figure out how to break the hypnosis and stop the villain before it's too late.
Well, perhaps they sneak out to meet a mysterious figure who claims to have information about Percy's father, Poseidon. But when they get there, it turns out to be a trap set by one of their enemies. They then have to use their wits and powers to escape and figure out who is behind it all.
Perhaps Annabeth is wrongly accused of a crime and is made a slave as punishment. Her friends, including Percy, try to prove her innocence while also dealing with the internal politics of the demigod society that allows such a cruel situation to exist. This could involve a lot of character development for all involved as they question the fairness of their world's laws and norms.
