Bella herself might struggle with her identity. She has been so caught up in the vampire world before, and now being with Jacob, a werewolf, she has to redefine who she is and where she belongs. She may also worry about how her human family and friends will react to her being with a werewolf.
Jacob might face challenges from other werewolves who see Bella as a distraction for him. They might think that his focus should be more on protecting the tribe rather than being in a relationship with a human girl. Also, there could be external threats from vampires who still have an interest in Bella, which could put their relationship in danger.
Sure. There might be some new characters created specifically for this fanfiction. Maybe a wise elder in the werewolf community who gives advice to Jacob about how to handle the situation with Bella and the pregnancy. Or perhaps a human friend of Bella's who discovers the truth and has to deal with the shock of the supernatural world.
A dominant Jacob is usually in touch with his alpha side. This means he has a natural leadership quality. He can command respect from others in the fanfiction world. And when it comes to Bella, this leadership translates into him guiding their relationship in a way that he believes is best for both of them. He may be more confident and self - assured, which can be both appealing and a source of conflict in the relationship with Bella.
Another plot could be that Jacob and Bella's dating is discovered by the Quileute tribe. Some members are against it at first because of the potential danger it could bring to the tribe. But Jacob stands up for their relationship and they work together to prove that their love can overcome the obstacles, and in the process, they strengthen their bond by facing these challenges head - on.
It would become more intense and complex. Jacob would be very protective, his werewolf instincts kicking in fully. He'd be constantly worried about Bella and the baby's safety.
One character could be Seth Clearwater. As a member of Jacob's pack, he could play an important role in their married life. Maybe he helps them out in times of trouble or is like a younger brother figure to their family.
It could lead to a whole new dynamic in the story. Maybe Jacob's feelings for Bella would become even more intense and complicated.
An unexpected guest could be a human who has some sort of special ability to see the supernatural world but has been hiding it. This person could come forward at the wedding and reveal that they know all about the vampires and werewolves and that they have a message from a higher power about Jacob and Bella's relationship. It would be very unexpected as no one expected a normal human to be involved in such a way.
Often, it portrays Jacob as being extremely protective of Bella due to the imprint. He is shown to put her needs above his own and be willing to sacrifice a great deal for her. For example, in many stories, he will fight against other threats, be it vampires or other werewolves, to keep Bella safe.
One popular fanfiction could be 'Bella's Solitude with Jacob'. In this, they might go on a journey into the forest alone, where they have deep conversations about their relationship and the challenges they face. This could lead to a stronger bond between them, away from the chaos of the werewolf - vampire drama.
In some fanfictions, Jacob and Bella's pregnancy can take on various plotlines. One possibility is that it creates a huge rift between the werewolf pack and the Cullens. Jacob's loyalty to Bella is tested as he tries to protect her and their unborn child from the potential threats in the Twilight world, like the Volturi. This situation often leads to a lot of drama and tension in the fan - created stories.
