One possible storyline could be about Bella's journey of self - acceptance. She might explore different ways to find fulfillment in life without having children, like focusing on her career or hobbies. Another could be her relationship with her partner. They could strengthen their bond in different ways, perhaps by traveling the world together or taking on new challenges as a couple.
A storyline could involve Bella's support system. Her friends and family might come together to help her deal with the situation. They could introduce her to new communities or experiences that are more inclusive of people without children. It could also show how she copes with the reactions of society, which may have certain expectations regarding motherhood.
Her partner could be a main character. He would play an important role in how Bella copes with the situation. They could have deep conversations about their future together and support each other through the emotional turmoil.
In the fanfiction, Bella could be involved in a mystery within the orphanage. There might be a secret room or a strange event that keeps occurring, and she takes it upon herself to solve it, which could also lead to her finding out about her real family or some other important aspect of her past.
One possible storyline could be that Annabeth uses her strategic skills to help Bella deal with the vampire and werewolf situation in Forks. Maybe she gives Bella advice on how to handle Edward's overprotectiveness or Jacob's pushiness.
One possible plot could be that Bolt and Mittens discover they are going to have babies unexpectedly. They then have to prepare their home for the new arrivals. Bolt might start training extra hard to ensure he can protect his family, while Mittens teaches the soon - to - be - born kittens about the outside world based on her own experiences.
A possible storyline could be that Bella discovers a long - lost family and gets involved with them, putting all her energy into getting to know her family members and heritage. Since she's so occupied with this new aspect of her life, Edward becomes an afterthought. Another storyline might be that Bella becomes a strong advocate for a cause, like protecting the environment or helping the less fortunate. Her focus on this cause is so intense that any feelings she might have had for Edward fade away. And perhaps in some fanfiction, Bella gets involved in a time - travel plot where she goes back in time to change certain events, and in this new timeline, she doesn't fall in love with Edward.
Another idea is that they get involved in vampire politics more deeply. With their unique family situation and Bella's newfound abilities, they could become important figures in the vampire world. They might work towards changing some of the old vampire laws and traditions, especially those related to hybrids like Renesmee.
There could be a storyline where Alice's dominance over Bella is a result of a premonition she has about Bella's future. So she becomes overprotective and starts dictating Bella's actions. For example, she might not let Bella go to certain places or meet certain people. This could lead to Bella feeling frustrated but also realizing that Alice might be right in the long run. It could also lead to a story where Bella tries to break free from Alice's dominance and in the process discovers something new about herself or the vampire world.
One possible storyline could be that Bella discovers her Winchester heritage and has to learn how to hunt supernatural creatures like the rest of the family. She might struggle at first, but with the help of Sam and Dean, she becomes a skilled hunter.
A really interesting storyline could be Bella trying to reconcile her old life in Forks with her new life as a Mikaelson. She might struggle with the differences in values and lifestyles. For example, the Mikaelsons are more into power plays and manipulation in the supernatural world, while Bella was used to the more straightforward (although still complex) relationships in 'Twilight'. This internal conflict could be a major part of the story, along with her trying to find her place within the Mikaelson family and the wider supernatural community.
One possible storyline could be that the hair tie is a memento from a special day. Maybe it was from a day she spent with a loved one, like Edward in the Twilight universe. The hair tie could be a symbol of a promise they made to each other, and throughout the fanfiction, she holds onto it as a reminder during tough times.
