Perhaps their relationship is based on mutual respect for each other's abilities. Leo respects Harry's unique way of thinking and approaching problems, and Harry looks up to Leo for his experience and wisdom. They might work together on various projects or quests, with Leo guiding Harry but also allowing him to take the lead sometimes, which helps to strengthen their bond.
Communication is key. They could start by having simple conversations about their daily lives, their likes and dislikes. This can slowly build a connection.
They could also develop their relationship through misunderstandings and then making up. Maybe Leo accidentally uses his powers in a way that endangers Percy. At first, Percy is angry, but then they talk it out. Leo explains that he was trying to protect Percy in his own way. This kind of communication and forgiveness would strengthen their brotherly bond.
One possible plot could be that Harry, as Leo's son, discovers he has some unique powers or abilities that are tied to his father's lineage. Maybe he lives in a world where Leo is a great hero or a powerful wizard, and Harry has to learn to control and use his powers while also dealing with the expectations placed on him because of who his father is.
Their relationship would likely become more centered around the baby. They would have to work together as a team to take care of it. There would be less time for just the two of them, but in a way, it would bring them closer as they share this new responsibility.
In the beginning, the relationship could be full of misunderstandings. Harry might expect Jasper to be a perfect father right away, while Jasper may be hesitant because he's not used to having a son. However, as they spend more time together, they could start to open up. For example, Jasper could teach Harry about his family history or special skills. Harry could in turn show Jasper a new perspective on life, and through shared experiences like facing a common enemy or helping others, their relationship would strengthen and become more like a real father - son relationship.
Her appearance could be developed in a unique way. She might have long hair that she has to figure out how to keep out of the way during battles. Also, her fighting style could be more fluid and graceful compared to the traditional male - dominated style.
Well, considering his parents, Harry in the fanfiction could have a very complex personality. From Piper, he might get a sense of determination and a strong will. Piper was always fighting for what she believed in, and Harry could do the same. From Leo, he could inherit a sense of humor and a laid - back attitude in some situations. But he'd also be a bit of a maverick, not afraid to break the rules if it means doing the right thing. He'd be someone who is confident in his abilities, which come from his powerful parents, but also humble enough to know he still has a lot to learn.
To develop their relationship believably, start with their existing personalities. Leo is known for his quick - wittedness and mechanical skills, and Reyna for her strength and leadership. Show how they complement each other. For example, Leo could use his skills to create something special for Reyna, which makes her see him in a new light. And Reyna's support could boost Leo's confidence. As they interact more, small gestures of kindness and understanding can gradually build up the romantic tension until it reaches the point of a deep connection.
Their relationship would likely become more committed. With a baby on the way, they would have to rely on each other more. Leo might become more protective of Karai during her pregnancy, and Karai would start to see Leo in a new light as the father - to - be. After the baby is born, they would be united in their love and care for the child, which would strengthen their bond.
Well, Harry, as the first son of Piper and Leo in fanfiction, could grow up in a world full of magic and mystery. Since his parents have such unique abilities, he could be a bit of an outcast among normal kids. But he'd also have a great support system at home. His story could involve him learning to control his powers, which might be a combination of Piper's and Leo's. He could also make new friends who are also different in some way, and together they could go on adventures to solve mysteries related to their powers.
