The characters could develop in terms of their relationships. Ruby and Weiss would have to strengthen their bond as a couple while raising a child. Their interactions with other RWBY characters might also change. For example, Blake and Yang could become like aunt figures to the kid. And as the kid grows, they would start to form their own relationships with the RWBY team, which could in turn affect how Ruby and Weiss develop as parents.
Ruby might develop into a more responsible and protective figure. With a kid, she would have to think about someone else's safety first. Weiss, on the other hand, could become more patient and nurturing. The kid would grow up learning from their parents, developing combat skills and a strong sense of justice.
For Ruby, she might develop her leadership skills further in the context of family. She could lead by example for her child, showing what it means to be a hero. Weiss could develop her softer side more, as she has to be a mother now. The kid would be influenced by their parents' growth, and in turn, their own development would also push Ruby and Weiss to keep evolving as people and as parents.
