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.
One possible plot twist could be that an old enemy shows up at the wedding. For example, a vampire from a different coven who has a vendetta against either the Cullens or the werewolves. Another could be that Jacob has a premonition right before the wedding that something bad will happen to Bella in the future, which makes him hesitant to go through with it. Or perhaps a long - lost relative of Bella's arrives and reveals a big family secret that shakes things up.
Bella might become more confident as she takes this step into a new life with Jacob. She could also become more assertive in dealing with the werewolf pack politics that come with being Jacob's wife.
Well, in Bella and Jacob wedding fanfiction, a plot twist might be that Jacob has a vision during the ceremony that shows a future filled with danger for Bella if they get married. Or perhaps Bella's long - lost relative arrives and reveals some shocking information about her heritage that could change the whole dynamic of the wedding. It could also be that the werewolf pack has some internal conflict right before the wedding that threatens to derail the event.
In some fanfictions, Jacob and Bella's wedding night might be depicted as a very romantic and tender moment. It could be filled with soft conversations, sharing of deep feelings, and a new level of closeness. Maybe they would talk about their future together, their hopes and dreams while looking into each other's eyes under the moonlight.
One common theme is the exploration of their new relationship. Since they have a complex history, the wedding night can be a time to fully embrace their love. Another theme could be the blending of their two different worlds, the werewolf and the vampire - adjacent. Also, the idea of new beginnings and a fresh start in their relationship is often explored.
Perhaps Neville's grandmother Augusta. She has always been a bit of a stern character, and at first, no one expects her to come. But she shows up with a beautiful family heirloom as a gift for Ginny. She might even give a short but heartfelt speech about how she has watched Harry grow and how proud she is of the young couple. This would be unexpected as she doesn't seem the type to be very involved in the social lives of the younger generation.
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.
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.
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.
