Some fanfictions show Squall learning to be more open about his feelings during Rinoa's pregnancy. He starts to communicate more, which is a big change for him. Rinoa's character might develop by becoming more patient, especially with Squall as he adjusts to the idea of being a dad. For example, she helps him understand the needs of a growing family.
Well, in certain fanfictions, Squall and Rinoa's relationship deepens during her pregnancy. Squall becomes more involved in domestic aspects of their lives. He might start thinking about things like a nursery or baby names, which he never did before. Rinoa, in turn, starts to see a different side of Squall, a more nurturing side. This development of their characters not only affects their relationship with each other but also how they interact with their friends and the world around them. Their pregnancy becomes a catalyst for personal growth for both of them.
In many fanfictions, Squall becomes more protective. His usually reserved nature softens as he anticipates becoming a father. Rinoa, on the other hand, grows in her sense of responsibility. She's no longer just the carefree girl but is preparing to be a mother.
