In a 'Percy and Sally Reunion' fanfiction, Percy could return after being presumed dead. Sally has been mourning him all this time. His sudden appearance shocks and delights her. They hug tightly and don't let go for a long time. Percy then shows Sally his new powers or skills he's acquired during his time away. They also plan for a future where Percy can stay closer to home and help protect it, and Sally is just happy to have her son back in her life.
How about a park? A park where Percy used to play as a child. There are big oak trees and a little pond. Sally could be sitting on a bench feeding the ducks when Percy comes up to her. The peaceful environment of the park would contrast with the adventures Percy has been on, making their reunion even more special.
Perhaps Sally has some ulterior motive for seducing Percy. Maybe she's trying to get information from him or is part of a plot against him that she later has a change of heart about. She could use her charm and beauty to draw him in. She might start by dressing in a way that catches his attention and then use her wits to keep him interested. Along the way, Percy could be initially oblivious to her intentions but then start to fall for her as well, leading to a complex relationship dynamic.
I'm not sure about the specific plot as it's a rather inappropriate concept. Fanfiction should generally be based on positive and ethical themes.
One day, Percy finally made his way back home. Sally, his mother, was in the kitchen when she heard the door open. She turned, and there was Percy. 'Mom,' he said softly. Sally rushed to him and hugged him tightly, tears streaming down her face. 'You're home, my son,' she whispered. They sat down and Percy told her about his latest adventures, how he had faced new monsters and made new friends. Sally listened intently, her eyes filled with pride for her son.
A possible plot in such a fanfic could be Percy trying to bring Sally back from the dead. He could go on a dangerous and forbidden quest, defying the gods and the natural order. This would put him at odds with many, but his love for his mother is so strong. He might encounter dark magic or make deals with shadowy figures in his desperation, all while his friends are worried about him losing himself completely in this quest.
Maybe in the fanfiction, Annabeth moves in to further study some ancient texts that Sally has access to. Percy is excited as he gets to spend more time with Annabeth. They face challenges like adjusting to living together, like who takes out the trash or does the dishes. But overall, they create a warm and loving environment, with Sally acting as a guiding figure for both of them.
One possible plot could be that Percy, Amphitrite, and Sally Lemon are brought together by a mysterious force. Maybe they have to work together to solve a problem in the underwater world that is also affecting the surface world where Sally lives. For example, a powerful ancient curse that is making the seas stormy and also causing strange phenomena on land. Percy, with his demigod skills, Amphitrite, with her knowledge and power of the sea, and Sally, with her human wisdom and tenacity, combine their strengths to find a way to break the curse.
Well, perhaps the tattoo is a key part of Percy's identity that he has been hiding from Sally. When she sees it, it could lead to a series of revelations about Percy's true nature, his loyalties, and his place in a different world. It might also cause some conflict between them as Sally tries to understand this new aspect of Percy.
One possibility is that they tell Sally about their latest adventure in the demigod world. Maybe they share details about a new monster they defeated or a mysterious place they discovered. For example, they could be telling her about a hidden temple filled with ancient magic that they had to navigate through to retrieve an important artifact for Camp Half - Blood.
One possible plot development could be Sally's intense anger and determination to protect Percy. She might seek justice against the abuser, which could lead to a showdown in the fanfic's world. Maybe she teams up with Percy's friends to expose the truth.
