To develop both of them, put them in challenging situations that force them to grow. For instance, they could be trapped in a maze where they have to rely on each other's strengths. Percy's physical abilities and his sister's mental acuity could be combined to get them out. This would not only show their individual growth but also strengthen their bond as siblings.
For Percy, you can show his protective side more when it comes to his sister. Have him be more cautious and less reckless in situations where her safety is at stake.
The little sister could be developed by giving her unique traits. For example, if she's really good at strategy, show her coming up with plans during battles or quests. Also, explore her relationship with the other characters in the Percy Jackson universe. Does she get along well with Annabeth? Or does she have a special bond with Grover? All these aspects can help develop her character.
You can start by giving her a distinct personality. Maybe she's really shy but has a fierce determination inside. For example, she might be quiet in group settings but when it comes to protecting her friends or family, she's fearless. Give her some hobbies too, like she loves to draw the different mythical creatures she's heard about. This can show her creativity and her connection to the world of the gods.
In the fanfiction, their relationship could start off rocky. Maybe the sister resents Percy for always being in the spotlight. However, as they face challenges together, like fighting a powerful monster, they start to understand each other better. Percy learns to listen to his sister's ideas, and she learns to trust his experience. Eventually, they become a great team and have a really close relationship full of mutual respect.
Give her a distinct personality. For example, she could be really curious, always asking questions about the demigod world. Make her brave but also a bit naive at times. She might be more in tune with nature than other characters, able to sense things about the environment. Another aspect is to show her relationship with Percy. She could look up to him and want to be just like him, but also have her own ideas about how to handle situations.
You can start by giving her a distinct personality. For example, if Percy is brave and impulsive, she could be more cautious and analytical. Show her interests, like if she loves art or is into science. Also, explore her relationship with Percy. Maybe she's a bit jealous of all the attention he gets, but also proud of him. Another aspect is her reaction to the demigod world. She could be initially skeptical and then gradually accept it.
She might start off as a shy character. But as the fanfiction progresses and she discovers her connection to lemons, she becomes more confident. For example, if she uses lemons to make a magical item, she realizes her own capabilities and starts to stand up for herself more.
Perhaps she's a sister who was thought to be dead but actually survived. She could have been corrupted by the experiences she had while being 'dead'. When she returns, she blames Percy for not saving her properly. This false blame leads her to betray Percy. She could start spreading rumors about Percy being a coward or a bad leader among the demigod community.
One way is through facing challenges together. For example, when they are on a quest, they might have to rely on each other's skills. Percy's sword - fighting skills and his sister's magic (if she has any) can complement each other. They also learn about each other's weaknesses and how to protect one another. In addition, they can have heart - to - heart conversations during quiet moments in their adventures, which will deepen their relationship.
Percy would likely be very confused at first. He'd probably feel a mix of anger and sadness. He might start to question his own actions and wonder if he did something wrong to make his sister leave.
One idea could be that his little sister discovers a new, hidden power within herself while on a quest with Percy. Maybe she can communicate with mythical creatures in a unique way that helps them solve a mystery.
Percy would likely become more mature. He has already been through a lot, but the relationship with Calypso would force him to think about a more permanent future. He might become more patient as well, as Calypso has her own traumas from being alone for so long. Calypso, on the other hand, would become more open. She has been isolated, but with Percy, she starts to trust more and interact with the outside world again. Her powers might also develop in new ways as she has a new purpose in life - to be with Percy and build a future together.
