One common theme is the family dynamic. Carlisle being the patriarch, his influence on Edward and Bella's relationship within the family framework is often explored. For example, in many fanfictions, he helps them navigate the difficulties of being part of a vampire family.
The theme of redemption also shows up. Carlisle, with his long life and past mistakes, can be a symbol of redemption. His journey can inspire Edward and Bella in their own relationship struggles, showing them that no matter what has happened in the past, there is always a way to move forward towards a better future.
Another theme is the power of love and self - sacrifice. Edward and Bella's love is central, and Carlisle's role in either supporting or challenging this love can be a major part of the story. In some cases, Carlisle might sacrifice his own desires for the sake of their relationship.
Another theme is the moral and ethical aspects. Carlisle has strong moral beliefs, and in fanfiction, this can clash or align with Bella and Edward's relationship. For instance, some stories might explore how Carlisle's medical ethics come into play when dealing with Bella's transformation or the consequences of their relationships in the vampire - human world.
The theme of self - discovery is quite prevalent too. Bella is often portrayed as a character who is on a journey of self - discovery, especially when caught between Carlisle and Edward. This includes understanding her own feelings, her place in the vampire - human world, and her future with either of them.
One common theme is the exploration of forbidden love. Since the relationship between these characters is rather complex in the original Twilight series, fanfiction often plays with the idea of love that goes against the norms set in the original story.
Another common theme is the idea of Bella's transformation in a way that is influenced by Carlisle. This could be in terms of her values or her understanding of the vampire world. For example, in some fanfictions, Carlisle helps Bella to see the good in the vampire existence beyond just being with Edward. It's about her growth and how Carlisle plays a part in it.
I really like 'A New Beginning in Forks'. In this fanfiction, Carlisle's wisdom has a great impact on how Edward and Bella handle the challenges in their relationship. It has a very engaging writing style that makes you feel like you're right there in Forks with them.
One popular theme is their father - son relationship. Since Carlisle is Edward's adoptive father in the Twilight universe, exploring the depths of their bond, how they communicate, and their mutual understanding is a common theme. Another is their different views on the vampire lifestyle.
There could be. Fanfiction writers like to take creative liberties with existing characters and relationships. But in the 'Twilight' series, Bella's relationship with Edward is central, and this kind of plot would be a major deviation. Some fans might write it to explore different character dynamics, but it may not be as common as more traditional fanfiction plots.
Another theme is their struggle with being vampires. They both have different ways of dealing with it, and fanfictions often delve into how they support each other in this aspect. For example, Carlisle's more pacifist approach might contrast with Edward's sometimes more impulsive nature when it comes to dealing with their vampiric instincts.
Another theme is the idea of eternal love. Since Carlisle is immortal, their love story often delves into the concept of loving someone forever and the sacrifices that come with it. Writers explore how their relationship endures through time.
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.
