Zoey could start as a somewhat naive character. But once pregnant, she'd become more assertive, making sure Logan steps up. Logan, initially a bit of a playboy, would be forced to reevaluate his life. He'd start to develop a stronger sense of loyalty and commitment, not just to Zoey but also to the unborn child. Their development would be shaped by the reactions of those around them and the challenges they face in preparing for parenthood.
One possible plot could be that they initially panic. Logan might feel a sense of responsibility he never had before. Zoey could struggle with how this will affect her future plans, like her education. They then start to bond over the impending arrival of the baby, learning more about each other and growing closer as a couple.
For Camille, you could give her a backstory that makes her pregnancy more complex. Say she has always dreamed of a big career and now she's not sure if she can achieve it with a baby.

If his family has strong opinions about the pregnancy, it can create internal conflict for him and show different sides of his personality.
Zoey might become more nurturing and selfless as she is about to become a mother. James could develop a stronger sense of responsibility and protectiveness towards Zoey and the unborn child.
One of their friends could be secretly jealous. This friend might feel left out as Zoey and Logan's focus shifts to the baby. However, through some events in the fanfiction, like Zoey and Logan reaching out and including this friend in the pregnancy journey, they would overcome this jealousy and strengthen their friendship.
To develop Logan's character, you could show his insecurities about becoming a father. Maybe he had a difficult relationship with his own father, and he's worried about repeating the same mistakes. For Camille, you could explore her fears of losing her independence. As the pregnancy progresses, Logan could start to become more confident in his role as a future father by taking parenting classes or reading books. Camille, on the other hand, could find a new sense of purpose in creating a loving and stable environment for the baby.
Ron could develop a deeper understanding of Ginny. He may realize how strong she is, especially when dealing with the physical and emotional changes during pregnancy.

This would strengthen their relationship and help them both grow as individuals.
If Zoey were to lose her memory and Logan was the only one who could help her remember, that would be a unique development. He could take her to all the places they used to go together and tell her stories about their past. This way, Zoey would see Logan in a whole new way, not just as the guy she knew casually, but as someone who really cares about her and has a deep connection with her.
Both of them could develop in terms of their relationship. The pregnancy can be a catalyst for them to communicate more openly, share their fears and hopes, and ultimately become a stronger couple.
