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.
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.
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.
One way is to put them in difficult situations where they have to rely on each other completely. For example, if they are trapped in a magical maze, they'll need to communicate well and trust one another to find the exit. Another is to introduce a new character who is interested in Peter romantically. This would make Wendy realize her true feelings for Peter and cause her to be more assertive in their relationship.
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.
To develop Peter further, he could be given more backstory about his childhood dreams. Maybe he wanted to be an artist but gave it up for some reason. For Lola, she could start taking self - defense classes which would show her determination to be stronger. This would also add new dimensions to their relationship as Peter might be worried about her getting hurt in the process.
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.
One way is to give them new shared challenges. For example, a powerful new villain comes to Neverland and they have to rely on each other's strengths more than ever. Their relationship can grow as they see different sides of each other while facing this threat. Another way is to explore their past more deeply. Maybe there were some unspoken words or moments between them that can be revisited and resolved, which would bring them closer.
Their relationship could be developed by having them face a difficult challenge together. For example, if Neverland was in danger of disappearing, they would have to rely on each other's strengths. Wendy's practical thinking and Peter's knowledge of Neverland's magic could combine to save the day. This would deepen their bond as they realize how much they need one another.
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.
