For Hestia, her character can be developed by exploring her relationship with the demigods more deeply. In the context of the lemon aspect, maybe she uses lemons as a symbol of purification. She could teach demigods like Percy how to use lemons in certain rituals to cleanse their spirits. This would show her nurturing side and her connection to the demigod world on a more practical level.
Well, one way to develop their relationship is to have Percy seek refuge at Hestia's hearth when he's in trouble. Hestia can offer him shelter and wisdom. As time passes, Percy can start to help Hestia with her tasks, like maintaining the peace around the hearth. They can also exchange gifts. Percy could give Hestia something he found on one of his adventures, and Hestia could give Percy a token of her power, which would strengthen their connection. Moreover, if Percy were to face a moral dilemma, Hestia could be his guide, and this would bring them closer together as Percy would come to rely on her more and more.
In a Percy Jackson and Hestia lemon fanfiction, it could be that Hestia uses her powers related to the hearth to create a lemon - like glow around Percy. This glow gives him an extra boost of energy during a battle. They form an unlikely bond, with Hestia seeing Percy as a symbol of hope for the future of the demigod world. And the lemon aspect could be metaphorical, like a fresh start or a new hope that Percy brings, much like the refreshing feeling of a lemon.
For Percy, he could be developed by showing his growth in understanding different magical elements like the significance of lemons in Calypso's world. For example, he starts to learn about the lemon - related magic that Calypso uses and becomes more attuned to her realm.
To develop the characters, consider how they interact with the lemon aspect. Percy could start off being a bit skeptical about all the lemon stuff his father is into. But as he spends more time with Poseidon in these lemon - related adventures, he could learn to appreciate it and grow as a person. Poseidon, on the other hand, could be developed by showing his pride in Percy when Percy uses the lemon - inspired powers or items he gives him. This could make Poseidon more relatable as a father figure.
Percy's development could involve him using his skills in a new way. For example, his ability to control water could be combined with Elsa's ice in creative ways. This would make him more adaptable. Elsa could develop by seeing Percy's loyalty to his friends and trying to form deeper connections herself. As they interact more, they could influence each other's values. Percy might become more patient like Elsa, and Elsa could become more bold like Percy.
The characters can be developed by giving them new relationships based on the setting. In the muck, they might meet new characters who are native to that area. Percy could learn from them how to survive in the muck. The lemon could play a role in these new relationships. For example, it could be a gift that Percy gives to a new friend in the muck, which helps to build trust. And as for his existing friends, they could have different reactions to the muck and the lemon, which shows more about their personalities.
For the female Percy Jackson, you can develop her character by showing her growth in understanding and using her powers. Since she has a connection to Poseidon, she could start off a bit unsure but as the story progresses, become more confident. As for the 'lemon' aspect, if there's a love interest, it can show her vulnerability and a different side of her. For Poseidon, show his fatherly side towards her, his pride or disappointment in her actions which can shape her character development as well.
Their relationship could start with Percy seeking refuge at one of Hestia's hearths during a difficult time. Hestia, being the gentle goddess she is, offers him comfort and wisdom. This initial encounter could be the foundation for a deeper bond as Percy starts to see Hestia as a motherly figure, much like how he saw Sally Jackson.
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.
A possible plot is that Hestia has a prophecy involving a demigod and a lemon. Percy is the demigod in question. Hestia reveals to Percy that the lemon is a key to unlocking a powerful weapon that can defeat an upcoming evil. They embark on a journey to find the lemon, facing various challenges along the way. During their travels, they develop a deep respect for each other. The lemon, when finally found, not only unlocks the weapon but also brings a new era of peace and cooperation between the gods and demigods.
