Another theme is adventure. Many fanfictions will put them in situations where they have to embark on a journey together. This could be to find a solution to a problem in the vampire community or to protect someone they care about. It gives a chance for their characters to develop and for their relationship to grow stronger in the face of challenges.
A third common theme is self - discovery. As they interact with each other, both Bella and Garrett often learn more about themselves. Bella may discover new aspects of her vampire nature through Garrett's influence, and Garrett might reevaluate his long - held beliefs because of Bella. This theme adds depth to their relationship and the overall story.
Friendship is also a prevalent theme. Bella often forms strong bonds with other characters. In some fanfictions, these friendships help her through difficult times or are the basis for her adventures. They add depth to the story and show different aspects of Bella's personality.
Garrett is often depicted as a very adventurous vampire. He has a nomadic nature and loves to explore different places. He's also quite brave, which is shown when he gets involved in various battles or dangerous situations. His sense of freedom is a big part of his character, and this can be very appealing to Bella who has often felt restricted in her own life.
One common theme is heroism. Garrett is often depicted as a hero when he saves Bella. This could involve him using his vampire abilities in a very dramatic way to rescue her from a perilous situation.
A major theme is the idea of breaking away from the expected. In the Twilight series, Bella's relationships were mostly centered around Edward and Jacob. In fanfictions with Garrett, it's about her branching out. Also, there's often a theme of self - discovery. As Bella interacts with Garrett, she discovers new sides of herself. This can be seen in many such fanfictions where their conversations or experiences lead Bella to reevaluate her beliefs and desires. For example, in some fics, Garrett introduces Bella to a different vampire culture, which makes her question her understanding of vampires in general.
One common theme is 'alternate universes'. Writers often explore what would happen if Bella made different choices or if the Twilight world had different rules. Another theme is 'power discovery'. Many fanfictions focus on Bella finding new powers or abilities she didn't have in the original story. 'Love triangles' are also common, where Bella may be caught between different characters in new and interesting ways.
Romance is also quite prevalent. Writers may develop a relationship between Bella and Garrett, exploring how they fall in love, overcome obstacles in their relationship, and grow closer. It could be a slow - burn romance or a more immediate attraction - based one.
Family dynamics can also be a theme. Since the 'bella sister' part implies a family connection, there could be elements of how their relationship affects the family or how the family reacts to their relationship. And perhaps there are themes of self - discovery as they navigate their relationship and the events around them.
One common theme could be identity crisis. Bella is used to being a certain person in the Twilight world, but as a Lestrange, she has to reevaluate who she is. Another might be power struggles. The Lestranges are often associated with dark magic and power, so Bella could be caught in the middle of that. Also, family secrets are likely to be a theme as the Lestrange family has many secrets.
Often, a common theme is the alteration of the Twilight universe. Since Bella is now a god, she can change the rules, the setting, and the fates of the characters. There is also the theme of self - discovery. Bella has to figure out who she is in this new role, which is different from her human self. Additionally, themes of morality may come up as she decides how to use her god - like powers.
One common theme is friendship. The OC often forms a unique bond with Bella, either helping her through tough times or just being a great friend. Another theme is the exploration of the supernatural world. Since the Twilight series has a lot of supernatural elements, the OC usually gets involved in that aspect too, like dealing with vampires and werewolves.
