One possible character development for Percy is that he becomes more isolated. Despite being Poseidon's brother, the other gods and demigods might view him with suspicion or envy. This could lead to him relying more on himself and becoming more self - sufficient. On the other hand, he could also become more of a leader among the demigods, using his new status to bring about change and protect his fellow demigods in different ways than before.
In this fanfiction, Percy might develop a more complex relationship with the other gods. He would be more of an equal to them, so he could be more involved in their politics. This would make him more calculating and strategic in his actions. Also, his loyalty to his friends might be tested in new ways as his new status brings new responsibilities.
Percy might become more disciplined. As a praetor in Camp Jupiter, he has to follow the Roman rules more strictly. He could also become more of a strategist, learning the Roman military strategies. For example, he might study more about siege warfare or troop formations.
Percy could become more in touch with his emotional side through Piper's influence. Piper, on the other hand, might gain more confidence in her combat abilities with Percy's training. For example, Percy could teach Piper some water - based combat techniques, and Piper could show Percy how to better understand and manipulate emotions in battle.
For Percy, he could become more in tune with the nature - related aspects of the mythological world because of his association with Artemis. He might develop a deeper respect for the wild and the creatures that Artemis protects. As for Artemis, she could learn more about the human side of things from Percy. Maybe she starts to understand the concept of friendship in a more human way rather than just the loyalty among her hunters.
For Percy, he might become more responsible. Marriage would mean he has to think about not just himself and his friends, but also his partner Reyna. He could develop better leadership skills as he and Reyna might need to lead their family or even the demigod community together. Reyna, on the other hand, could become more open - hearted. She has always been a bit guarded, but with Percy as her husband, she might let her walls down more often. She may also develop a softer side, especially when it comes to dealing with Percy's more impulsive nature.
It can also make Percy more empathetic. Since he has such a powerful and protective father, he realizes the importance of protecting others too. He may be more likely to step in and help those in need, just as Poseidon does for him. This protection also gives Percy a sense of security that allows him to explore his own identity and powers more freely. He doesn't have to constantly worry about being alone or unprotected, so he can focus on growing as a hero and as a person.
One main theme is family. Since Percy and Poseidon are brothers, the exploration of their family ties, loyalty, and how they support each other is common. Another theme is identity. Percy has to figure out who he is now that he's related to a major god. Power is also a theme. As Poseidon's brother, Percy may have new powers or a different relationship with power.
Well, the theme of discovery is quite prominent. Percy discovers his relation to Poseidon and then has to discover all that comes with it. Another theme is conflict. There could be conflict with other gods who might not be happy about Percy's new - found status. And finally, the theme of growth. Percy has to grow and adapt to his new role as Poseidon's brother, which often includes changes in his personality and relationships.
One possible theme could be family reconciliation. Since Percy and Poseidon have had a somewhat rocky relationship at times, a cuddle scene could symbolize them mending their differences and growing closer as father and son.
Perhaps it's part of a grand plan that Poseidon has, one that he believes will ultimately benefit Percy but in the short - term causes him pain. For example, he might be trying to toughen Percy up or make him prove himself in a more extreme way, thinking it will help Percy in the long run.
