A possible plot could be that Bella and Elijah are from different species in the fanfiction world, for example, one is a vampire and the other a werewolf (assuming such a scenario exists in this fanfic). Their pregnancy is then a very unique situation that defies the norms of their world. This could lead to a lot of drama, with different factions either trying to protect or harm them because of the baby. They would have to rely on each other and a few trusted friends to navigate this new and dangerous situation.
One idea could be that Elijah discovers he is going to be a father during a time of great turmoil in the supernatural world. His family's enemies might see this as a weakness and target him and his unborn child. Another plot could involve Elijah trying to protect the mother of his child from the dangerous vampire politics and ancient curses that could harm her or the baby. Maybe he has to make a deal with a powerful witch to ensure a safe pregnancy for the mother.
Perhaps the fanfiction could explore the challenges they face due to their different natures. Elijah being a vampire and Bonnie being a witch. There could be concerns about the health of the baby, with Bonnie using her magic to ensure a safe pregnancy and Elijah struggling with his vampiric instincts, like the urge to drink blood while being around his pregnant partner.
One idea could be that they face challenges from the supernatural community due to their unborn child's potential power. The other vampires or witches might see the baby as a threat or a valuable asset. Another plot could be them preparing for the arrival in a world full of danger, like building a safe haven and gathering allies.
One plot idea could be the challenges they face in keeping the pregnancy a secret from their enemies. Another could be how they prepare for the arrival of the baby in a world filled with supernatural threats. For example, they might have to find a safe place away from the constant power struggles in their supernatural community.
One idea could be that Emmett and Bella face unexpected challenges during the pregnancy. Maybe the vampire - human pregnancy has some unique medical issues that they have to deal with. For example, Bella's body might react in strange ways because of the baby's half - vampire nature.
One idea could be that they face challenges from their families. Maybe Bella's family is initially shocked and has to come to terms with the situation. Another could be that they have to deal with the gossip in their small town. For example, people might spread rumors about how it all happened so quickly.
One idea could be exploring how the pack reacts to Bella's pregnancy. Maybe some are protective while others are worried about the implications for the pack. Another could be the relationship between Seth and Bella as they prepare for the baby. Seth might be overjoyed and extremely helpful.
Perhaps a plot where they try to find a way to ensure the baby has a normal life. They might search for ancient vampire or human lore that could help. It could also be interesting if they face external threats during the pregnancy, like other vampire covens who see the baby as a threat or an opportunity.
Well, a possible plot could be that they discover the pregnancy is special in some way. For example, the baby might have unique powers. This could lead to a journey of discovery for Bella and Seth as they try to understand what it means for their future and the future of their community. They might seek out the help of older, wiser members of the werewolf pack or other supernatural beings they know.
Well, perhaps in the fanfiction, they go on a journey to find a way to ensure the baby's safety. Since Bella was previously involved with the vampire world through Edward, there could be some vampire - werewolf tension regarding the pregnancy. Also, they might have to deal with the reactions of their human friends and family, like how they'll explain this rather strange situation.
