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.
Another possibility is that the baby sister could be a plot device to bring out different sides of Bella. If the sister gets into trouble with the wrong supernatural elements, Bella would have to go to great lengths to save her. This would show Bella's determination and love for her family, highlighting her growth from the somewhat self - centered girl in the beginning of the Twilight series to a more selfless and family - oriented person.
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.
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.
They are friends at first. Jacob has a crush on Bella, but Bella is initially in love with Edward.
They could start off with a bit of friction as they are likely to have different personalities. But over time, they would grow closer. Maybe through shared experiences like going to school together or dealing with family problems.
In the fanfiction, their relationship could be one of mutual admiration. The baby brother could look up to Hermione as a role model, seeing her as a source of inspiration. And Hermione could be in awe of how quickly he picks up new things, like magic spells or concepts, and they could bond over their shared love for magic.
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.
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.
One possible plot could be that Harry has to protect Bella from some sort of magical danger in their world. Maybe there are dark wizards after Bella because she has some special power, and Harry uses his skills and knowledge to keep her safe.
In the fanfiction, Hermione and her older sister could have a complex relationship. Maybe the sister is overprotective, constantly looking out for Hermione at Hogwarts, especially with all the dangerous situations she gets into. The sister could also be a bit jealous of Hermione's academic success and magical abilities, which could lead to some sibling rivalry.
The connection between them is multi-faceted. It's influenced by different factors like their personalities and the events unfolding. It keeps readers on their toes.
