They could be given a new shared hobby. Say they both start taking painting classes. Through this, they discover new aspects of each other's personalities. Elizabeth might be more competitive than Peter thought, and Peter might have a creative side that Elizabeth finds endearing. This new common ground would add depth to their relationship.
One idea could be a story where Peter and Elizabeth take a vacation to a small, idyllic town. While there, they stumble upon an art heist mystery. Peter can't resist getting involved, and Elizabeth uses her charm and wits to help him solve it, all while strengthening their relationship.
Another aspect could be Elizabeth's own thoughts and feelings during the pregnancy. She might be worried about how her pregnancy will affect her relationship with Peter, especially considering his demanding job. She could also be excited about starting a family and all the changes it will bring.
Elizabeth's confidence may grow even more as she becomes the mistress of Pemberley. She could start taking on more social responsibilities and use her intelligence to make positive changes in the community. Darcy, on the other hand, might become more open and less reserved as he is influenced by Elizabeth's warm and sociable nature. He may start to show his emotions more freely and be more involved in the daily lives of those around him.
One way to develop their relationship further is through facing challenges together. Let's say there's a drought in Neverland and they have to find a way to bring water back. During this process, they rely on each other's strengths. Peter uses his flying skills to search for water sources from above, while Wendy uses her kindness and ability to communicate with the animals to find hidden springs. As they work together, they grow closer and start to understand each other on a deeper level. Also, they could have a bit of a misunderstanding, like Wendy thinking Peter doesn't care about her as much as she thought. But then they talk it out and their relationship becomes stronger because they learn how to communicate their feelings better.
Elizabeth's pregnancy in fanfiction could show her dealing with morning sickness. In the White Collar world, this might be a bit difficult as she is often around the action. Maybe she tries to hide it from Neal at first because she doesn't want him to worry too much.
Their relationship could be developed through more shared secrets. For example, Poseidon could reveal a long - hidden prophecy about Percy that only he knows. This would create a deeper bond of trust between them.
Their relationship could be developed further through mutual understanding. For example, Naruto could learn more about Kurama's past and the reasons for his anger and hostility in the beginning. This would make Naruto more empathetic towards Kurama, and Kurama in turn could start to trust Naruto even more.
In fanfiction, their relationship could be further developed by having them communicate in new ways. Maybe Toothless discovers a new form of communication that only Hiccup can understand. This could lead to more in - depth conversations between them. Also, they could have a falling out over something, like a misunderstanding about a dragon's behavior. But through this conflict, they'll learn more about each other's feelings and come out with an even stronger bond in the end.
To develop their relationship further, they could have a shared goal that is not just about survival or fixing a problem. For instance, they might decide to build a special place in the forest, like a sanctuary for injured animals. This would require them to plan together, make decisions together, and see each other in a different light. They could also exchange gifts that are meaningful to them. Diaval might give Aurora a feather from one of his forms, symbolizing his trust in her. And Aurora could give Diaval a piece of jewelry made from a precious stone found in the forest, showing that she values him. These small acts of kindness and connection would enhance their relationship.
Peter could be developed further by having him face a personal fear. Maybe he has a fear of losing his connection to Narnia completely. Caspian, on the other hand, could be developed by exploring his relationship with his people on a deeper level. He could be shown dealing with the everyday problems of his subjects, which makes him more relatable and also shows his growth as a king. Their characters could also be developed through their interactions with each other. They could have friendly competitions that teach them both about their own strengths and weaknesses.
