In the fanfiction, perhaps the story focuses on the emotions of Hayley and Elijah. Hayley could be dealing with the physical and emotional changes of pregnancy, while Elijah tries to be the supportive partner. They might also have to deal with prophecies or ancient curses related to their unborn child. For example, there could be a prophecy that the child will bring great change to their world, and they have to figure out how to handle that.
One possible plot twist could be that their love is forbidden by some ancient vampire or werewolf law. Maybe there are forces within their respective supernatural communities that oppose their union. This could lead to them having to fight for their love, and perhaps even having to go into hiding to be together.
The main characters are obviously Hayley and Elijah. Hayley is often portrayed as a strong and independent character, and in this fanfiction, she would be the one carrying the baby. Elijah is known for his noble and protective nature, and he would be by Hayley's side throughout the pregnancy.
Perhaps the plot could involve Elijah being initially shocked by the pregnancy news. The OC, on the other hand, is determined to keep the baby. As time goes by, Elijah realizes his love for the OC and the unborn child, and they start building a future together, facing things like finding a proper place to live and getting ready for parenting.
Well, it could be about how they deal with the unexpected pregnancy. Maybe they struggle to accept it at first, then gradually come to terms and start preparing for the baby.
Maybe the pregnancy was unexpected and it forces Bonnie and Elijah to re - evaluate their relationship. They might have been in a somewhat tenuous relationship before, and now they have to come together for the sake of the baby. There could be a journey of them learning to trust each other more deeply, dealing with family reactions (Bonnie's witch friends and Elijah's vampire family), and ultimately finding a way to build a future for their new family.
One possible plot could be that Caroline's pregnancy changes the dynamics of her relationships. Her friends might rally around her in a different way compared to when Hayley was pregnant. For example, Klaus could be more protective of Caroline, seeing her carrying a child, and this could lead to a whole new set of interactions and power plays within the supernatural community they inhabit.
The fanfiction could start with Hayley suspecting she is pregnant again. She tells Klaus in a very emotional moment. Klaus, who has grown since their first pregnancy, is now more ready to be a father. They could then face challenges like finding a way to raise the child in a world full of supernatural beings that may not always be friendly towards their family. There could be a journey of self - discovery for both of them as they prepare for another child.
Family is also a big theme. As they are part of a complex supernatural family, the fanfictions might explore how their marriage affects the family dynamics. They could be trying to protect their family together or dealing with family members who don't approve of their union. In some stories, they might also be thinking about starting their own family, which adds another layer of depth to the plot. Another common theme is power. Given their positions in the supernatural world, their marriage could change the balance of power, and fanfictions often play around with this idea.
One possible plot twist could be that Hayley discovers she's pregnant with twins this time. It would add more drama and challenges to the story, like how she and her partner would prepare for two babies instead of one.
One possible plot could be that Elijah and Elena find out about the pregnancy unexpectedly. They then have to deal with the reactions of their friends and family. There might be some who are happy and supportive, while others are shocked or even against it. They would also need to figure out how to prepare for the baby, like finding a suitable place to live and getting all the necessary baby items.
