In this type of fanfiction, a common plot could be Carlisle and Bella exploring different cultures together. Carlisle, with his long life and vast knowledge, could introduce Bella to things she never knew. They might travel to different places, both modern and historical, and encounter various supernatural beings along the way. This would not only strengthen their relationship but also expose Bella to new aspects of the supernatural world that she was only starting to understand before becoming Carlisle's wife.
One interesting plot could be that Dark Carlisle has some hidden powers that Bella discovers. This discovery could lead to a series of adventures where they have to face off against some new and powerful enemies in the vampire world.
Some fanfictions might explore a plot where Carlisle and Bella are forced to be together in a situation where they have to rely on each other for survival. Maybe they are trapped in a dangerous place filled with other menacing vampires or some other supernatural threat. This would lead to them bonding on a deeper level and their relationship evolving in a way that is different from the typical courtship.
Mainly, it's Carlisle, a sophisticated and noble vampire, and Bella, a character full of curiosity and love. Their relationship is central. But we can't forget about the other vampires in their world. For example, Edward could be an interesting character in this fanfiction. He was once in love with Bella, and his reaction to her being with Carlisle could add a layer of drama. Also, Esme, Carlisle's adoptive mother in a sense, could play a role in either accepting or having some doubts about their union.
One interesting plot could be Bella growing up in the Cullen family with Carlisle as her father. She might inherit some special vampire traits early on and have to deal with the unique challenges that come with it, like hiding her abilities from humans. Another plot could involve her relationship with the other Cullens, perhaps having a different dynamic with Edward as her 'brother' which changes the whole Twilight love story.
A plot that stands out is when they all go on a journey to discover more about their vampire heritage together. This allows for a lot of character development and interesting interactions. For example, Carlisle can share his long - held knowledge, Esme can offer her emotional support, and Bella can bring her unique perspective as a new addition to the vampire world.
Perhaps a plot where Renesmee is in some sort of danger and Carlisle has to protect her in a way that makes them realize their deeper connection. This could involve them facing an unknown enemy together and relying on each other more than ever. In the process, their relationship might start to change in the context of the fanfiction.
Well, one interesting plot could be how Bella and Damon first met in the fanfiction world. Maybe it was a chance encounter at a supernatural event. Another plot could involve them facing challenges together, like dealing with other supernatural beings who are against their relationship.
One possible plotline could be Carlisle teaching Bella more about the history and ethics of the vampire world. For example, he might take her on trips to ancient vampire sites and share stories passed down through the ages.
One possible plot could be the challenges they face in preparing for the baby in a world where they are vampires. For example, how they would deal with their unique vampire family's reactions. Another could be the discovery of new vampire - related abilities during the pregnancy. Maybe Esme could have some sort of enhanced empathy during this time.
Well, in some Carlisle Esme pregnant fanfictions, there could be a plot where the baby has some special abilities even before birth. This might lead to other vampires being either intrigued or threatened. Also, Carlisle's role as a doctor and a father - to - be would be interesting to explore. He'd be in a unique position to monitor Esme's pregnancy and the development of the baby.
