The baby sister might also attract the attention of other supernatural beings. If she has an alluring scent like Bella, it could draw vampires or werewolves towards her. This would force Bella to take on a protective role and might lead to new alliances or battles in the Twilight universe. For example, the Cullens and the werewolves might have to work together more closely to keep the baby sister safe.
Her presence could also bring about a shift in Bella's priorities. Instead of just focusing on her relationship with Edward and the vampire world, she now has to consider her sister's future and well - being. This could lead to Bella making different choices, such as staying in Forks longer than she originally planned or getting involved in local supernatural politics to ensure her sister has a safe environment to grow up in.
Love and friendship are also common themes. The baby sister may find love among the supernatural beings or form strong friendships. For example, she could become friends with some of the werewolves while also having a connection with the Cullens. It adds a new layer to the existing relationships in the Twilight world.
Well, it completely changes Bella's family dynamic. In the original, she's a human girl with a normal family, but in this fanfiction, being Aro's sister makes her part of the vampire world from the start. This would likely change her relationship with the Cullens. Instead of being an outsider who they protect, she might have her own power and influence within the vampire community.
There is a fanfiction called 'Bella's Little Sister's Adventure'. In this story, the baby sister embarks on her own journey in the Twilight world, facing challenges and making unique friendships. It's a great read if you like seeing a different perspective in the Twilight universe. The author does a good job of integrating the new character into the existing world and storylines.
The makeover can give Bella a new confidence and change how others perceive her. It might also lead to new plot developments and relationships.
The baby sister in fanfiction could also have special abilities. Maybe she has a latent psychic ability that she discovers as she grows up. Bella, with her knowledge of the supernatural, could help her sister understand and control these powers. This would create a strong bond between them, different from a typical sister relationship, as they navigate the challenges of these unique abilities together.
The sister could have a big impact. Suppose she has a gift of reading minds like Edward. She might be able to tell if Edward has any hidden motives towards Bella. If she senses something wrong, she'll surely try to break them up. But if she approves of Edward, she could actually be a great confidante for both of them, and help them communicate better when they have misunderstandings.
It can add a new perspective to the fandom. Fans who are tired of the typical Bella - Edward love story might find these fanfictions refreshing. It shows that relationships are complex and not always about happily - ever - after. It can also inspire discussions among fans about the characters' flaws and what could realistically happen in such a relationship.
Often, Bella's injury can add drama. It can make the readers worry about her future in the team. If she's the star player, the team might struggle without her on the field at first. This can create suspense as to whether she'll recover in time for important games.
Her relationship with Bella would likely become more complex. As a vampire, she would have different needs and instincts. She might be more protective of Bella in a way that Bella doesn't understand at first. For example, she could sense danger towards Bella that a human wouldn't notice. But at the same time, Bella might be a bit afraid of her sister's new vampire nature, which could create some tension between them.
One common theme is family dynamics. Since it's about Bella's sister, it often explores how the sister fits into the family structure, especially with Bella being so central in the original Twilight story. Another theme is love triangles. Just like in the original, but now with the sister involved in some way.
