One common theme is family loyalty. The sister often stands by Bella through all the strange events in Forks. Another theme is self - discovery. As the sister witnesses Bella's experiences, she also starts to learn more about herself.
The exploration of the supernatural world from an outsider's perspective (the sister's) is also a common theme. She is not as directly involved as Bella in the vampire - werewolf drama at first, but as the story progresses, she gets more and more entangled. This allows for a unique view of the world that has been created in the Twilight universe.
Well, identity is a major theme. Bella has to figure out who she is now as a Winchester sister. There's also the theme of power. She might gain new powers or abilities in this new setting, or learn to use her existing ones in different ways. And of course, there's the theme of love and loyalty, not just within the family but also towards the cause of fighting the bad guys.
Well, a frequently seen theme is the integration of the baby sister into the Twilight - inspired world. This could involve her discovery of the supernatural elements that Bella is already aware of. Also, growth and self - discovery are common. The baby sister often goes through her own journey of finding out who she is, especially in relation to being in Bella's shadow or forging her own path. In addition, friendship is a theme, as she makes friends in Forks and how those relationships compare to Bella's friendships.
Well, often there's the theme of self - discovery. Bella might discover new aspects of herself through her relationship with the sister witch twins who are her soulmates.

'Love triangles' are also common, where Bella may be caught between different characters in new and interesting ways.
Romance can also be a theme, not necessarily between Bella and the wolf girl sister, but in relation to the overall world of Twilight. The wolf girl sister might have her own romantic interests, or Bella's romantic situation with Edward or Jacob could be intertwined with the story of the sister. This can add an extra layer of drama and complexity to the fanfic, as the relationships are navigated in the context of their sisterly bond.
