Well, their life could be filled with a lot of supernatural drama. They'd probably have to deal with the politics of the supernatural world together. Maybe they'd be really protective of each other. For example, Rebekah with her vampire strength and Hayley with her werewolf abilities would make a formidable team against any threats. And they'd also have to navigate their relationships with other characters in the fanfiction universe.
Perhaps it starts with an unexpected alliance. They might be forced to work together against a common enemy, like a powerful witch or an ancient vampire. During this time, they start to see the good in each other. Rebekah might admire Hayley's tenacity and Hayley could be intrigued by Rebekah's charm.
Rebekah was significant as she was the one chosen to be Isaac's wife. Her kindness at the well was a sign that she was the right person. Her role was crucial in continuing the family line of Abraham through Isaac.
It could be Marcel. He has a long - standing relationship with the Mikaelson family, and his connection with Rebekah could deepen during her pregnancy. He might be the one to support her through the difficult times.
There could be Klaus. Since he is Rebekah's brother, he would likely be part of Bella's life in some way. He might be a protective uncle or a source of conflict if he has different ideas about how Bella should be raised. Another character could be Elijah. He might act as a mentor to Bella, teaching her about their family's history and values.
Davina could be an ally too. She has a good heart and her own powers as a witch. She might be sympathetic to Hayley's situation and use her magic to create protective spells around Hayley and the baby. Also, she could act as a mediator between Hayley and the other factions in the city, given her relationships with different groups.
One great Klaus and Hayley fanfic is 'A New Beginning'. It beautifully explores their complex relationship in a post - war scenario. The author does an amazing job of showing how they support each other through difficult times.
Character development is a big characteristic. As the story progresses, both Stefan and Rebekah usually change. Stefan might become more lenient towards Rebekah's flaws, and Rebekah might start to develop a more empathetic side due to Stefan's influence. This transformation of their characters within the fanfiction is what makes it so appealing to many readers. Fanfictions also often explore their pasts, like Stefan's history with the Salvatore family and Rebekah's long - standing issues with her own family, the Originals, and how these pasts shape their relationship in the present.
