Paul Blofis should be in it. Since he's Sally's husband, his presence would add an interesting layer to the family dynamic in the fanfic. He could be involved in some humorous situations when it comes to understanding Percy's demigod world.
In developing Percy, consider his identity. He is half - god, half - human. In the fanfic, he could struggle more with this identity and Sally could play a role in helping him accept it. Sally can be developed by highlighting her creativity. She could come up with unique solutions to problems they face. Regarding their relationship, develop it by adding conflict. Maybe Percy wants to do something dangerous and Sally is against it. Resolving this conflict can lead to a deeper understanding between them and thus develop their characters further.
One popular theme could be family bonds. Given the relationship between Sally and Percy, exploring how their family connection endures through different challenges in the fanfic can be really interesting. Another theme might be adventure. Since Percy is known for his adventures in the original series, it could be continued in the lemon fanfic with Sally also being involved in some way, like she gives Percy advice on how to face certain perils. Also, self - discovery can be a theme. Percy may discover new aspects of himself with Sally's guidance and support, which could be a great emotional arc in the fanfic.
One idea could be a fanfic where Sally tells Percy stories about his father from her own perspective before he knew the truth. It would give a deeper look into their relationship and how Sally coped with the knowledge of Poseidon.
One great fanfic could be 'The Unspoken Bond'. It delves deep into the mother - son relationship between Sally and Percy. It shows how Sally's love has been a constant source of strength for Percy throughout his adventures. The author beautifully portrays the small, everyday moments of their relationship that are often overlooked in the original series but are crucial to understanding their bond.
The relationship between Percy and Sally is really special in the original books, and fanfic about Sally allows us to explore her character more deeply. We get to see different sides of her that might not have been fully shown in the main series.
Percy might be very confused at first. He would wonder why his mother, who has always been there for him, suddenly left. He could start to question if he did something wrong. In some fanfics, he may go into a state of denial, not wanting to believe that she's really gone.
Percy would be extremely angry. He loves his mother deeply, and her disownment would feel like a huge injustice. He'd probably want to immediately go and confront the people who disowned her. Maybe he'd also feel guilty, thinking it's his fault as a demi - god that his mother is in this situation.
One possible fanfiction could be about Sally Jackson making lemonade for Percy and his friends during a hot summer day at Camp Half - Blood. It could show a warm mother - son moment between Sally and Percy, with the lemonade as a symbol of comfort and home in the midst of the chaos of the demigod world.
