Another theme is the idea of protection. Esme, being an older and more experienced vampire, often takes on the role of protecting Bella in these fanfictions. It could be from other vampires, from the secrets of the vampire world, or from Bella's own self - destructive tendencies. This theme of protection can lead to a deep emotional bond between them that is explored in the stories.

At first, it would be a bit awkward as Bella adjusts to her new life. But Carlisle would be very patient and understanding, like a father figure. Esme would be more of a motherly presence, always there to comfort Bella. As time goes on, they would become closer. Carlisle might teach Bella about the vampire history and ethics, and Esme would share her love for the family and home. Eventually, they would have a very strong, loving bond.
One great fanfiction is 'The Cullen Family Bonds'. It beautifully explores the relationships between Carlisle, Esme, and Bella. It shows how Carlisle's wisdom and leadership in the family interact with Esme's nurturing nature, and how Bella fits into their world.

Another theme is the supernatural aspect. Given that they are part of a world with vampires and werewolves, fanfictions might explore how their relationship is affected by these elements. Maybe they face some supernatural threats together and it deepens their bond.
