They could have a fight and then make up. It's a classic way to develop a relationship. Maybe Nico does something Percy doesn't like in the name of protecting him, and they argue. But then they realize they were both just trying to look out for each other and become closer.
Put them in a situation where they have to rely on each other completely, like being trapped in a magical maze. They'd have to communicate, trust each other's abilities, and support one another. Through this, their brotherly bond would strengthen as they see each other's strengths and weaknesses up close.
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.
You can start by having them share a common goal. For example, they both need to retrieve a powerful artifact that has been stolen and is being used for evil. As they search for it, they face obstacles that force them to rely on each other. This builds trust gradually.
A good way to develop their relationship is through mutual self - discovery. They could each have insecurities or secrets that the other helps them face. For instance, Percy might be struggling with his identity as a son of Poseidon and Triton could share his own experiences of growing up as a sea god's son, which would create a deeper connection between them.
In fanfiction, they could develop a relationship based on shared goals. Let's say there is a new threat to the gods and the demigods. Percy and Athena have to work together to defeat it. During this time, they learn about each other's strengths and weaknesses. Percy learns from Athena how to plan better and Athena learns from Percy how to be more adaptable in the face of unexpected situations. As they face challenges side by side, their relationship deepens.
Often through shared adventures. When they are in dangerous situations together, they start to trust each other more. For example, if they are in a battle against a horde of demons, they need to watch each other's backs. This mutual reliance deepens their bond.
Well, it could start with mutual respect. For example, Percy respects Artemis's power and her role as a goddess. Artemis, in turn, could come to respect Percy's courage and his ability to survive against all odds. They could then start to work together on small tasks, like protecting a particular area from monsters. As they spend more time together, they might start to trust each other more, and their relationship could grow deeper.
The relationship could start with hostility. Percy is aware of Circe's reputation for turning men into animals. But then, as they are forced to work together to overcome a mutual obstacle, like a powerful monster attacking Circe's island, they begin to see each other in a new light. Percy realizes Circe has her own reasons for her actions in the past, and Circe sees Percy's courage and loyalty.
One way is through shared challenges. Let's say there's a problem in the Weasley family, like a financial issue. The twins and Percy have to work together to solve it. Percy uses his organized thinking, while the twins bring in their creative solutions. As they overcome the challenge, their relationship grows. They might start to respect each other more and see the value in their different personalities. Also, having them participate in a Hogwarts - wide event, like a magical tournament where they have to rely on each other's strengths, would also strengthen their bond.
The relationship could start with Percy being curious about Kronos. He could research the Titan in the hopes of finding a weakness. This initial interest could lead to some strange interactions, like Kronos communicating with Percy through visions. As Percy delves deeper, he might start to understand Kronos's motives, which could create a complex dynamic.
One way to develop their relationship is by having them go on a long - term quest together. On this quest, they are isolated from the rest of the camp and have to rely solely on each other. At first, they might argue a lot because of their different personalities. Percy is more laid - back and impulsive, while Thalia is more serious and cautious. But as they face various challenges, like fighting off hordes of monsters or solving ancient riddles, they start to adapt to each other's ways. Thalia might learn to be a bit more spontaneous from Percy, and Percy could become more cautious because of Thalia. This mutual growth and adaptation would strengthen their relationship.
