In the fanfiction where Bella is Sam's mate and Bella is scared, what are the possible reasons for Bella's fear?

He could be a bit confused at first. Maybe he doesn't fully understand why Bella is so scared. But then he would likely start to take steps to ease her fears. He might open up to her more about their relationship and what it means, so that she feels more in control and less frightened.

One reason could be the allure of the vampire - human relationship in both the Twilight and Vampire Chronicles universes. Writers might want to combine the two to see how Bella's experience with vampires like Edward in Twilight could translate to a relationship with Lestat.

One possible reason is that the fanfiction distorts the original relationship between Bella and Sam in a way she finds unacceptable. For instance, if it creates a false romantic tension where there shouldn't be one.

One possible plot point could be the initial discovery of their mate bond. It might be a moment of shock or instant connection for Bella and Sam.

One reason could be the allure of the 'forbidden love' aspect. Stefan is a vampire and Bella has her own complex relationship with vampires in her original story. This makes their potential relationship full of tension.

One key element is the exploration of a different relationship dynamic. Instead of the traditional pairings in the original story, Sam and Bella's connection brings new angles to the story. Another element is the way their relationship affects the surrounding characters. For example, how the werewolf pack reacts to Sam having Bella as his mate.

One possible plotline could be that Marcus discovers Bella's blindness and is initially hesitant about their relationship but then grows to see it as something that makes her unique and special. He might then become very protective of her.

Power dynamics could also be a theme. The Volturi are powerful vampires, and Bella is a human. Their relationship would involve a complex power dynamic. Demetri would have to protect Bella from other threats, but also control his own vampire instincts. And Bella would have to find a way to assert herself in a relationship where she is physically weaker but perhaps emotionally stronger.

Power dynamics could be a theme as well. Depending on how their relationship is written, there could be a power struggle or a harmonious balance of power between them. Additionally, the theme of family and community might play a role. How do their respective vampire families or communities react to their being mates? This could add an interesting layer of conflict or support to the story.

There's a fanfiction named 'Sam and Bella: A Different Mate Story'. It's a bit different from the usual ones. Here, Sam and Bella's relationship starts off rocky as Bella is initially resistant to the idea of being Sam's mate. But as the story progresses, they start to understand each other more and their relationship blossoms in a very natural and believable way.
