One possible theme could be redemption. Since Jane and Alec may have had a less - than - good past, through Bella's adoption, they could be on a path of redemption.
Family is another theme. Bella is creating a new family unit by adopting them. It could explore what it means to be a family, especially in a non - traditional sense.
Growth and change would also be a theme. As they enter a new environment with Bella, both Jane and Alec are likely to experience personal growth and change in their characters and worldviews.
The 'bella adopts jane and alec fanfic' might start with Bella having a strong sense of compassion for Jane and Alec. She could take them in and provide them with a loving home. This would likely change the trajectory of their lives. There could be many plot twists as they adapt to living with Bella. For instance, they may have to face the reactions of others in the community who know about their past. But through it all, Bella could be the guiding light that helps them become better versions of themselves.
Common themes include family unity. Since Bella is now part of their family, there's often a focus on how they all come together, support each other, or face challenges as a unit. Identity is also a theme. Bella's identity is now different as she is related to Jane and Alec, and she has to navigate that. And then there's the theme of acceptance. How do the other characters accept Bella as their sister? And how does Bella accept her new family situation? These are all things that are frequently explored in this type of fanfiction.
Another plot could involve Bella's relationship with the Volturi leaders when they discover that she is the mother of Jane and Alec. There might be a power struggle or a negotiation for the custody or future of the two children. For example, she could be in a difficult position as she wants to keep her children safe but also doesn't want to start a full - scale war with the Volturi.
One possible scenario in this fanfiction could be that Bella's character is re - imagined in a very different context. Maybe it delves into how her relationship with the Volturi changes due to this new family dynamic. For example, she might have a more protective role over Jane and Alec, and this could lead to conflicts with the other Volturi members who are used to having a certain level of control over the twins.
Well, it depends on your definition of 'good'. There are fanfictions that explore this concept in different ways. Some may take a more dramatic approach, like Bella being a long - lost sister and the shock and adjustment that comes with it for all of them. Others might be more light - hearted, focusing on the sibling banter and relationships. You have to dig around a bit on the fanfiction platforms to find the ones that suit your taste.
One popular theme is the exploration of a forbidden love between Bella and Alec. Since they are from different 'worlds' in the Twilight universe, this creates a lot of tension and drama.
One more theme is the discovery of self. As Bella and Alec become mates, they often learn more about themselves through their relationship. They might discover new strengths or weaknesses. For instance, Bella could find that she's more courageous when it comes to protecting Alec, and Alec might find that he's more patient because of Bella. Also, the theme of family and how their relationship affects those around them is often explored. Their bond might change the dynamics within their respective families or friend groups.
One common theme is the forbidden nature of their relationship. Since Bella is often associated with the Cullens and Alec is a Volturi, their relationship goes against the norms of their respective vampire groups. Another theme is power struggle. Alec has his power within the Volturi and Bella often has to deal with the power dynamics around her.
Perhaps there's a plot twist where Bella's human past comes back to haunt her in this new role. For instance, old enemies from her human days find out about her new family and try to use Jane and Alec against her. This would add a whole new layer of conflict and drama to the fanfiction.
One common theme is love and growth. Bella's love for the baby makes her grow as a person. Another theme is family. The new addition of the baby creates a new kind of family for Bella. And also, there could be a theme of sacrifice. Bella may have to sacrifice some of her own desires or time to take care of the baby.
