A 'Bella has anorexia' fanfiction could imply a more complex view of the Twilight world's beauty standards. It could show how Bella, who is often seen as an 'average' girl in the story, might struggle with body image in a different way. This could also lead to a discussion about how her friends and family in the story would react and support her or not.
I'm not entirely sure if there is a specific 'Bella has anorexia' Twilight fanfiction. There are so many fanfictions out there that it's hard to keep track of all the different themes. But given the nature of fanfiction and how it allows for creative exploration, it's very possible that someone has written about this. It could be an interesting, if somewhat dark, take on Bella's character.
One implication could be that she is a huge fan of the Twilight series and wants to explore different storylines within that universe. Fanfiction often offers unique takes on the original story.
One possibility is that Bella's secret could be about her having some special power that she has been hiding from everyone in Forks. Maybe she can communicate with animals secretly, which adds a new layer to her relationship with the werewolves.
It could be a form of creative but very extreme deviation. Maybe the author was trying to explore gender - bending concepts in a really radical way, but this is a very extreme take on it. However, it's still not in line with the general spirit of the 'Twilight' series. In a more general sense, some fans might just be experimenting with ideas without fully considering the implications or the respect for the original work.
In some fanfictions, Bella might be kidnapped by a new vampire species that is trying to understand the relationship between humans and vampires. They see Bella as an important specimen since she is so deeply involved with the Cullens. So, they take her away to run tests on her, not with any malicious intent initially but more out of scientific curiosity. Another idea is that a witch or a magical being in the Twilight universe kidnaps Bella. They might believe that Bella's connection to the vampires has some sort of magical significance that they can use for their own gain. For instance, they could think that her blood has some special property that can enhance their magic. A more simple plot could be that a human who is jealous of Bella's relationship with Edward kidnaps her. This human might be someone who has a crush on Edward and thinks that by getting rid of Bella, they can have a chance with him.
Perhaps Bella starts taking ballet lessons in Forks, and through her ballet journey, she meets other characters who are also involved in the arts. This could introduce new sub - plots and friendships. It might also attract the attention of the Volturi, who could see her newfound passion as either a threat or something they want to use for their own purposes in the Twilight universe.
Perhaps in the fanfiction, Bella has been influenced by a darker force. It could be a new vampire or some other supernatural entity that has turned her into a bully. This external influence could be warping her mind and making her act out against those she once cared about or new people in Forks.
It could also send the wrong message if not handled carefully. For example, if it seems to be glorifying or justifying abuse in any way. However, if it's written well, it could potentially raise awareness about the issue of abuse. For instance, by showing the psychological and physical effects on Bella, it could make readers more empathetic towards real - life victims. But this is a very fine line to walk in the world of fanfiction.
It could be really interesting. For one, it might give the characters a different perspective on their own stories. They could see how fans view their relationships and adventures. Maybe they would be amused or even surprised by some of the creative interpretations in the fanfiction.
In the fanfiction, it might imply that Bella has been transformed into a puppy wolf for a specific purpose. It could be part of a prophecy or some kind of magical experiment gone wrong. This discovery would likely lead to a lot of self - discovery for Bella as she figures out what it means to be in this new form and how to navigate the world around her.
