Another way to develop them is through their interactions with other characters. If they have friends who already have kids, Char might be eager to get advice, while Ella might be a bit more reserved. And when it comes to their own relationship, Char could be the more affectionate one during the pregnancy process, while Ella might be more focused on the physical changes and how to stay healthy for the baby.
One possible story could be about their journey towards having a baby. It might start with them discussing their desires and fears. For example, they could worry about being good parents. Then they might start preparing a nursery, choosing baby names, and going through the process of getting pregnant, like dealing with doctor visits and fertility concerns.
Their relationship could become more tender. Char would be more protective of Ella, always making sure she's comfortable and safe. Ella might rely on Char more during this time, and they would have deeper conversations about their future and the family they're creating.
Cristina might become more empathetic. Usually very focused on her work, having a baby could make her see the world from a different perspective. She might start to understand the importance of family more. Owen, on the other hand, could become more patient. Dealing with Cristina's concerns and the new baby would require a lot of patience. He might also become more protective of his family.
One possible plot idea could be that Ella and Char face new challenges in their kingdom due to her pregnancy. Maybe there are those who oppose their rule and see the pregnancy as a weakness or an opportunity to undermine them. They would have to deal with political intrigue while also preparing for the new life. Another idea is that Ella discovers she has some new magical abilities during her pregnancy that are related to protecting the unborn child. And they could also focus on the relationship between Ella and Char growing stronger as they anticipate the arrival of their baby.
To develop their characters, start with their backstories. For Ella, you could think about her family. Maybe she comes from a poor family but has big dreams. For Thomas, perhaps he is from a noble family but feels trapped by the expectations. This can shape their personalities and goals.
As the baby grows, it could also influence the development of Beauty and the Beast. For instance, the baby's need for a normal life could push the Beast to be more involved in the outside world, and Beauty might have to learn how to balance her family life with the challenges of the outside world. Their love for the baby would be a driving force for their own personal growth and the growth of their relationship.
For the main character carrying the baby, you could start by showing her as an ordinary person who is suddenly thrust into this wild situation. She could be strong - willed and determined to face it head - on. As for Loki, show his different sides. He might be initially dismissive but then gradually show more concern and protectiveness.
In the fanfic, the twins could also have relationships with other characters. Maybe they befriend some of the local children. The boy could bond with other boys over sword - playing and the girl could form friendships with other girls who are interested in learning about politics or magic. These external relationships would also shape who they become and how they interact with their family. For instance, if the boy gets into a fight with a friend, it could cause some tension at home as his parents deal with the situation, and this would in turn affect his relationship with his sister as she might take sides.
One way it could develop is that the baby has some special powers that attract the attention of villains. Naruto and Sasuke then have to protect the baby while also trying to teach it right from wrong. As the baby grows, it could start to have its own dreams and goals, which might be different from what Naruto and Sasuke expect, adding more drama to the story.
Eleanor could develop from being a bit unsure of herself as a mother to becoming a strong and confident caregiver. She might learn new skills like making baby food from scratch or creating a safe haven for the baby. Jasper, on the other hand, could develop his protective instincts even further. He would become more vigilant and willing to sacrifice everything for the safety of his family.
