Well, in many fanfictions about Bella and Jacob from the start, their bond is one of an unspoken connection. Jacob is attracted to Bella in a different way than Edward is. He represents the more down - to - earth, warm - hearted option for Bella. He's there for her, like when she's feeling lonely or confused, and this forms the basis of their relationship in the early parts of the fanfiction stories.
One key event is their first meeting. It's a moment that often sets the tone for their relationship. Another is when Jacob helps Bella with something, like fixing a car perhaps. This shows his practical side and his willingness to be there for her.
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.
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.
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.
Edward might save Bella from Jacob when Jacob tries to force Bella into a life she's not ready for, like fully embracing the werewolf world. Edward, loving Bella as he does, would not stand for that and would rescue her.
In many Twilight fanfictions, the scenario of Edward saving Bella from Jacob can be quite intense. It often plays on the complex love triangle dynamic. Edward might save Bella from Jacob in a physical altercation, perhaps when Jacob's wolf instincts get out of control. This could be a way to reaffirm Edward's role as Bella's protector in the eyes of the fans who are rooting for their relationship.
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 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.
