You can also develop their characters through their interactions with other characters in the fanfiction. If there are friends or family members involved, how Bella and Will react to their opinions and support (or lack thereof) can say a lot about who they are. For instance, if Bella's family is against the pregnancy, does she stand up to them? And how does Will support her in that situation? This can all help to flesh out their characters more fully.
For Bella, you could show her growing in confidence as she deals with the pregnancy. At first, she might be scared and unsure, but as time goes on, she could become more assertive in making decisions for herself and her unborn child. For example, she could start taking charge of her prenatal care and making plans for the future, which shows her strength.
Will could be developed as a character who is initially in denial about the pregnancy. He might be focused on his own goals and dreams, and the pregnancy throws a wrench in those plans. But then, as he sees Bella's determination and starts to feel the baby move, he could gradually become more involved and protective. This transformation in his character would be interesting to explore.
Well, it's possible that the kiss makes them realize they are not as compatible as they thought. Maybe they have different views on how to handle the powers in the H2O world. So, instead of a smooth progression, their relationship could take a step back as they try to figure out if they really belong together.
One possible plot twist could be that the pregnancy is not as straightforward as it seems. Maybe there are some magical or supernatural elements involved in Bella's pregnancy that Will has to figure out. For example, it could be that an ancient spell has been cast on Bella which causes her pregnancy, and this spell has some hidden intentions or consequences that will unfold throughout the fanfiction.
To develop the story, start with their reaction when they find out about the pregnancy. Are they shocked, happy, or scared? Then, think about how their relationship changes. Maybe they become more protective of each other.
One common theme is friendship. Fans often explore how Will and Bella's friendship develops over time, especially considering Bella's mermaid secret. It's about their loyalty and how they support each other.
Bella might develop into a more confident and motherly figure. Since she's been through pregnancy before, she would be more prepared this time, but still face new challenges. Edward, on the other hand, could become more conflicted. He loves Bella and their unborn child, but is constantly worried about the dangers that lurk. Jacob, if he's still in the picture, might be a bit jealous at first but then come around to support them. He could also be a protector of the family in his own way.
One great Will and Bella fanfiction could be about their adventures in the underwater world. Maybe they discover a new part of the ocean that has special powers related to their abilities in H2O. They could face challenges together and grow closer as friends or more. It would be filled with descriptions of the beautiful underwater scenery and their unique bond.
