What are some possible plotlines in the 'Percy is Annabeth's father' fanfiction?

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.

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.

A possible plotline could be a mortal who becomes friends with Percy and Annabeth without knowing their true nature at first. As the story progresses, they start to notice strange things about their friends. Another plotline could involve a mortal who is caught in the middle of a demigod battle. They have to rely on Percy and Annabeth to keep them safe while also trying to understand what's going on.

In some fanfictions, this scenario could be used as a turning point in their relationship. Percy seeing Annabeth in such a vulnerable state could make him realize his deeper feelings for her. He starts to see her not just as a friend and teammate, but as someone he has strong romantic feelings for. This could lead to a series of events where he tries to court her in his own clumsy way.

One possible plotline could be that Percy is under some sort of mind control. Maybe a new villain has the power to manipulate his thoughts and actions, making him turn against Annabeth. For example, the villain could use Percy's insecurities about his past mistakes to drive a wedge between them. He might start by leaking some of Annabeth's secret plans to the enemy, causing her to be in danger without realizing Percy is the source.

One plotline could be that they face danger from an old enemy who sees the unborn child as a threat. So they have to protect themselves and the baby. Another could be that Annabeth has some premonitions about the baby's future and they embark on a quest to understand what it means.

A possible plotline could be a moment of surprise or shock. For example, Annabeth might straddle Percy in a moment of panic during a training exercise gone wrong, like when a magical creature suddenly appears and she jumps on him for protection. Then they have a humorous exchange about the situation.

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.

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.
