Well, it would likely bring a whole new level of complexity. Bella being the mother means she has a different kind of authority. She might be more protective than before. For example, she could be stricter with the younger Cullens in terms of their interactions with humans. Also, her relationship with Edward would shift from being his lover to also being his mother - figure in a way, which could be quite strange and might lead to some internal family tensions as they all adjust to this new dynamic.
In this fanfiction concept, Bella as the Cullens' mother would completely transform the family. She'd have a maternal influence that would impact every aspect of the family. Her values, which were formed during her human life and her transition, would be passed on. Maybe she'd teach them the importance of love and sacrifice in a different way than Carlisle did. Her relationships with each family member would be redefined. With Rosalie, there could be a new - found respect as Bella tries to understand her better in a mother - daughter - like relationship. And with Emmett, she might be more lenient as she sees his more carefree nature. Overall, it's a huge shift in how the Cullen family functions.
It would change everything. In the original story, Bella is drawn to the Cullens on her own. But if Victoria is her mother, Bella might be more reluctant to be around them because of her mother's enmity towards them. The Cullens would also be very cautious. Edward, for example, might not be as quick to fall in love with Bella. There could be a lot of suspicion and mistrust on both sides, and Bella would be in the middle, trying to understand her new role in this complex situation.
In this fanfiction, the relationship between Bella and Edward is turned on its head. Bella's role is now to shape Edward's character from a young age. Their interactions will be less about the intense passion of the original story and more about the tender, sometimes difficult, bond between a mother and son. She might worry about his future, his choices, and his safety in a way that is very different from the love - based concerns in the original narrative.
It also makes her more patient. Vampire children, or even adult vampires she might be mothering in the fanfiction, can be difficult to understand and manage. Bella has to learn to be patient with their different ways of thinking and behaving. For example, if they don't understand human emotions like love in the same way, she has to patiently explain it to them.
Her presence can introduce a whole new layer of backstory. For instance, if the fanfiction focuses on Joker's origin, Bella's relationship with him can be a key factor in shaping who he becomes. It could be that her actions or inactions lead to his transformation into the Joker.
Well, it shakes things up quite a bit. For one, Edward's relationship with Bella changes in a new way. They are now on more equal footing as vampires. The family has to adjust to having a new vampire in the house. Carlisle, as the head of the family, has new responsibilities towards Bella. He has to guide her in the vampire ways.
One possible plotline could be Bella trying to keep the family together during a time of external threat. Since she's the mother, she feels a strong sense of responsibility. Another could be her dealing with the individual problems of each Cullen family member, like helping Alice with her visions or Jasper with his control over his thirst. And she might also have to deal with the family's reputation in the vampire world, making sure they are seen in a positive light.
Well, at first, the Cullens might be more suspicious of Bella since she's related to James. But as they get to know her better, they might see that she's different from her brother.
Often, she is portrayed as a very empathetic character. Since she is Mother Nature, she has a deep understanding and love for all living things. So she might be shown as someone who is always ready to help a wounded animal or a dying plant.
She would become more protective. Since she has children to look after, her focus would shift from her own personal adventures to safeguarding Jane and Alec.
Bella's character development in this fanfiction might be seen in her emotional growth. Initially, she might be a bit naive and overly curious about the Cullens. But as she grows up with them, she becomes more understanding and empathetic towards their situation. She may also learn to control her emotions better, especially when it comes to the dangerous aspects of the vampire world. For instance, instead of panicking all the time, she starts to think rationally and find solutions. Moreover, her relationships with the Cullens shape her into a more complex and well - rounded character. Her bond with Edward might deepen in new ways, and her friendships with the other Cullens could also influence her values and behavior.
