A great plot could be that Annabeth touches Percy during a training session. She corrects his stance by placing her hands on his shoulders and adjusting his posture. This physical contact makes Percy a bit flustered at first, but then he focuses more on the training. As they continue, their bond grows stronger through these small touches. Another possibility is that they are in a crowded place, and Annabeth reaches out to touch Percy's hand to make sure they don't get separated. This leads to them holding hands for a while, and both start to realize their feelings for each other are deeper than they thought.
One idea could be a moment of comfort. Maybe Percy has had a really tough battle and is shaken up. Annabeth touches his hand gently to let him know she's there for him, and this simple touch leads to a deep conversation about their future together. It could also be a situation where they are exploring an ancient ruin. Annabeth touches Percy's arm to stop him from triggering a hidden trap, and from there, they work together to decipher the secrets of the place. Another plot idea could be a dream sequence where Annabeth's touch has a magical or prophetic meaning, and they have to figure out what it all means in relation to their quest.
One idea could be their first meeting at a summer camp for demigods. Maybe Percy is lost and Annabeth, being the smart one even as a kid, helps him find his way around. Another plot could be them teaming up for a camp quest. They might face a minor monster together and learn to rely on each other's strengths, like Percy's courage and Annabeth's intelligence.
Perhaps there's a curse on their neighborhood that only they can break. They have to work together, using Percy's powers over water and Annabeth's wisdom. They might start by researching in the local library, then go on adventures around the area to find clues. Along the way, they meet new characters, some friendly and some not, and their relationship grows stronger as they overcome each obstacle.
In a fanfiction about their bickering, a plot could be centered around a magical item. Let's say they find a new weapon or artifact. Percy wants to use it right away to test its power, but Annabeth is worried about the potential consequences and unknown abilities of the item. This leads to their bickering. Additionally, they could bicker about their relationships with other characters. For instance, Percy is friendly with a new demigod who Annabeth is a bit suspicious of, and this causes tension and arguments between them.
One idea could be that Percy and Annabeth are on a pirate ship, and they discover a hidden treasure map. They have to battle other pirates and sea monsters to reach the treasure. Another could be that they are pirates who are trying to free a group of captured demigods. A third idea is that they are pirates on a quest to find a magical artifact that can control the seas.
One idea could be a post - quest moment where Percy and Annabeth are sitting by the Camp Half - Blood lake at sunset. They start sharing their deepest fears and hopes, and as they get closer emotionally, they hold hands and share a gentle kiss. It's a very tender and intimate moment that shows their deep connection.
Well, a great plot could be that they find a mysterious object under their bed. It turns out to be a key to an ancient demigod treasure. So they start researching in bed, looking through old scrolls and books, trying to figure out where this treasure might be. And during this process, they also share some sweet and tender moments, reminiscing about their past adventures. Also, they could be in bed during a stormy night at Camp Half - Blood and tell each other spooky stories about the monsters they've faced, which leads to them coming up with new strategies for future battles.
One idea could be a modern-day high school AU. Percy could be the new kid at school, a bit of a loner and a troublemaker. Annabeth, on the other hand, is the top student and part of the student council. They get paired up for a project and initially clash because of their different personalities. But as they work together, they discover they have more in common than they thought, like their love for the ocean (Percy's always been drawn to it, and Annabeth has a fascination with ancient sea civilizations).
Maybe they are rivals in a quest given by the gods. Each wants to prove themselves as the better hero. Percy uses his combat skills and connection to the water, while Annabeth uses her strategic mind and knowledge of ancient places. This could lead to some intense moments where they have to decide whether to cooperate or keep competing.
Well, they could face issues like how to balance their heroic duties with their married life. For instance, Percy might get called away on a quest right when they planned a romantic dinner. Or perhaps in the fanfiction, they start a school for demigod children together as a married couple, which would bring its own set of comical and heartwarming situations.
They could discover a lost civilization in Tartarus. This civilization might have a way to manipulate the very fabric of Tartarus itself. Percy and Annabeth would then have to learn the ways of this civilization in order to use it to their advantage. Maybe they have to earn the trust of the civilization's leaders by helping them with their own internal problems first.
