Highlight their shared responsibilities. Marius could take on tasks like building a nursery while Cosette focuses on taking care of herself during the pregnancy. Their mutual support and division of labor would be a great way to show the development of their relationship during this special time.
Show their increased closeness. Marius might be more protective of Cosette now. He could accompany her everywhere, from doctor visits to simple walks in the park.
Perhaps in the fanfiction, Cosette discovers she's pregnant at a time when there are political unrests in their city. Marius is involved in some sort of movement, and he has to balance his duties towards the cause and his family. Cosette, on the other hand, is worried about the safety of their unborn child. They have to rely on their friends and each other's love to get through this tough time, and the pregnancy becomes a symbol of hope in the midst of chaos.
One potential side character could be the Thenardiers. They might try to take advantage of Cosette's pregnancy, thinking they can get some money or favors from Marius and Cosette. Madame Thenardier could be especially devious in her plans. Another side character could be a kind midwife in the neighborhood. She would help Cosette throughout her pregnancy, giving her advice on health and child - rearing. And of course, Gavroche, Marius's little friend, could be around, bringing some cheer and a sense of innocence to the story.
A good plot could revolve around Cosette's pregnancy cravings and how Marius tries his best to fulfill them. It could also show how they deal with the financial aspect of having a baby. Maybe Marius takes on extra work, and they learn to budget together.
You can write about how they communicate more deeply. For example, Casey might start to notice all the little things Lily does differently now that she's pregnant, like the way she sleeps or her new food cravings. They could have late - night talks about their fears and hopes for the future. This helps to strengthen their bond.
Another theme could be the exploration of their individual growth within the relationship. For example, how Marius becomes more understanding of Cosette's past, and how Cosette becomes more confident in their relationship. It's about how they change and adapt to each other.
Maybe some of the old foes from their past could resurface as antagonists. For example, those who were against Marius and Cosette being together in the first place might see the new baby as a way to cause trouble. They could try to spread rumors or create difficulties for the new family.
One possible plot could be that Marius and Cosette are new parents and they are adjusting to life with a baby. They face challenges like sleepless nights and learning how to take care of the baby's needs. But through it all, their love for each other and for their new child grows stronger.

During the pregnancy, Hermione could grow in her understanding of different cultures as Thorfinn comes from a different background. She might incorporate some of his cultural elements into their baby's future. Thorfinn, on the other hand, could develop a new respect for magic as he sees Hermione use it for the well - being of their unborn child. He could also become more patient and less impulsive as he anticipates fatherhood.
Mikan's character development could involve her learning about motherhood. She could start having dreams about the future with her child and Natsume. This would make her more determined to be a good mother. Natsume, on the other hand, might develop a sense of purpose. Before, he might have been a bit lost, but now with the pregnancy, he has something to strive for. Write about their internal thoughts and how they communicate these changes to each other to show their development.
