The fact that Carlisle has lived for so long and has a certain set of values and experiences that are vastly different from Bella's can be a problem. They may have different views on things like life, death, and love itself. Additionally, in the vampire world, there could be other vampires who oppose their relationship for various reasons, such as jealousy or a belief that it goes against the natural order of things.
In the fanfiction, Carlisle's sense of duty to his family and the vampire code might be a hurdle. He has to balance his feelings for Bella with his responsibilities to the Cullen family. Also, Bella's own human life and her relationships with other humans, like her father, could be a complication. How can she maintain those relationships while being in love with Carlisle? There's also the issue of secrecy. Their relationship has to be kept hidden from the outside world to protect both of them.
In some fanfictions, their relationship might start with Carlisle being drawn to Bella's unique spirit. He, as an older and more experienced vampire, is intrigued by her resilience. Maybe he first notices her when she enters the Cullen family's orbit, and from there, a slow - burning attraction begins to form as they interact more and get to know each other on a deeper level.
No. In the original "Twilight" series, Bella is in a relationship with Edward, and Carlisle is more like a father figure. Writing such fanfiction goes against the original intention of the story and may also violate the ethical and moral boundaries of the fanfiction community.
He becomes more vulnerable. Usually, Carlisle is seen as this strong, composed leader. But when he falls in love with Bella, his emotions start to get the better of him at times. He might second - guess his decisions more often.
The Cullen family members are important characters too. Edward, for example, might have an interesting dynamic with Bella in this fanfiction. He could be either protective or jealous of Carlisle's special relationship with her.
One common theme could be the exploration of a forbidden or unexpected relationship. Since Carlisle is an older, more reserved character and Bella has her own set of relationships in the original series, this pairing is quite different. Another theme might be the re - imagining of the Twilight world's power dynamics and how this relationship would affect the other characters around them.
In such fanfiction, the slow - burning aspect of their love is significant. It's not instant but builds over time. Carlisle's restraint as a vampire who has lived for a long time and Bella's growing understanding of his world create a unique dynamic. Also, the idea of Bella being a bridge between Carlisle and the human world he once knew can be an important part of the story. It gives a sense of connection and nostalgia for Carlisle, which deepens his feelings for Bella.
One popular theme is the forbidden love aspect. Since Carlisle is much older and in a different position in the vampire world compared to Bella, this creates a sense of the relationship being taboo, which makes for an interesting story.
One common theme is the exploration of forbidden love. Since Carlisle is an older vampire and Bella is a human (initially), their relationship goes against the norms of both the vampire and human worlds.
One alternative is to focus on their family - like relationship. Carlisle could be portrayed as mentoring Bella in her new vampire existence, like teaching her about self - control and the history of their kind. This would stay true to the nature of their characters in the original work.
Another one is 'The Unlikely Affair'. This fanfiction presents a scenario where Carlisle and Bella's love story unfolds in a more secretive and dangerous way. It's full of twists and turns as they try to keep their relationship hidden from the Cullen family and other vampires, all while exploring the depth of their feelings for each other.
