There could also be other characters from the Twilight series involved. For example, the members of Jacob's wolf pack might play a role. They could be trying to mediate between Jacob and Bella, or they might side with Jacob, adding more tension to the story.
Perhaps Jacob could start to spread negative rumors about Bella among their mutual friends. This would create a rift not only between them but also within the larger group that they are a part of. He may feel betrayed by Bella for some reason and wants others to see his side.
Bella is surely a main character. Since she's pregnant, her journey of dealing with the pregnancy, her emotions, and her future plans are key. Jacob, despite leaving, will still be important as his departure sets the story in motion. There may also be other characters like Bella's family or friends from the Twilight series, such as Charlie or Alice. They could be involved in Bella's life during this time, providing support or causing additional drama.
Bella herself could also be a significant character in this fanfiction. Her relationship with Jacob and her sister would be crucial. Her reactions to any potential relationship between Jacob and her sister could drive the story forward. Also, other characters from the Twilight series like Edward might make appearances, especially if they are involved in the overarching story related to Bella.
In some fanfiction, Bella might not forgive the Cullens because of a perceived betrayal. For example, if they hid something crucial from her again. It could also be due to them putting her in danger without her consent. Another reason could be a broken promise related to her transformation or her relationship with Edward.
Charlie, Bella's father, would probably be a significant supporting character. He might be initially shocked but then come around to support Bella and Jacob in raising the baby. The wolf pack could also be important. They might offer their protection and guidance to Jacob as he becomes a father.
Perhaps in the fanfiction, Edward broke a significant promise to Bella. Promises are important in relationships, and if he failed to keep one, it could lead to her not forgiving him. For example, if he promised to always be there for her but then abandoned her in a time of need. Also, his over - protective nature in a wrong way could make Bella feel suffocated and less likely to forgive him.
The main characters are Bella and Jacob, of course. Bella is a human girl who has a special connection with the supernatural world around her. Jacob is a werewolf, and in this fanfiction, he is Bella's mate.
There could also be new characters introduced in the fanfiction. Maybe a doctor who specializes in the unique situation of a human - werewolf pregnancy, or a friend who has been through a similar experience and can offer advice to Jacob and Bella. But overall, Jacob and Bella remain at the heart of the story.
In addition to Jacob and Bella, other characters from the Twilight series might also play important roles. Edward could be one of them. His presence, even if Bella is imprinted on by Jacob, can still create a lot of tension and drama. Also, the members of Jacob's pack, like Sam and Leah, could be significant as they are part of Jacob's world and might have different views on his imprinting on Bella.
It's Jacob and Bella. Jacob, who has feelings for Bella that are a mix of loyalty, love, and protectiveness. And Bella, who is caught between different worlds. In this Christmas fanfiction, they are the main characters through which the story unfolds. We might see them dealing with family - like the werewolf pack for Jacob or Bella's human family, and how they all come together (or not) during Christmas. There could also be elements of their relationship with other Twilight characters like Edward in the background, which could add tension or drama to their Christmas story.
