Their relationship in the fanfiction would be much deeper on a historical and family level. Since Jasper is her great - grandfather, he would know a great deal about the family's history and secrets. This would create a different kind of bond compared to the Twilight series. Bella might be more curious about her family roots and Jasper could be the key to unlocking all those secrets. He could share stories about their family's past, which would not only strengthen their relationship but also give Bella a new perspective on her place in the vampire - human world. It could also lead to some interesting interactions with the other Cullens, as they would now see Bella in a new light, having this direct connection to Jasper.
The development of their relationship in fanfics can be quite complex. Some fanfics might show Jasper using his gift to calm Bella's nerves, which then becomes a way for them to get closer. As they interact more, Bella may start to see Jasper in a new light, not just as a member of the Cullen family but as a potential love interest. Their relationship might also be affected by the events in the Twilight world, such as battles with other vampires. These events can either bring them closer together as they rely on each other for support or create new tensions. But overall, in these fanfics, the relationship between Bella and Jasper often evolves from a simple attraction to a multi - faceted and passionate connection.
One plot idea could be exploring Jasper's past and how it might have influenced Bella's family in unexpected ways. For example, his experiences in the past could have led to certain family traditions or hidden powers in the family that Bella discovers later.
It would change the love triangle aspect completely. Instead of Edward - Bella - Jacob, it would be Jasper - Bella. This would lead to different interactions between the characters. For instance, Jacob might not be as involved in Bella's life as he was in the original story. The focus would shift from Edward's attempts to protect Bella from his vampire nature to Jasper's way of dealing with it. And the Cullen family's reactions to this new pairing would be a major part of the story.
Their relationship would change in that they would have to be more open and communicative. Since Twilight is new to their world, they would need to share their experiences and knowledge freely. This would make their bond stronger. For example, Jasper might teach Twilight how to better use her senses in combat situations, and Alice would show her how to dress and present herself in the vampire society. This would create a deeper sense of family among them.
It would likely shock and confuse many characters. For example, Edward would be very surprised and perhaps a bit jealous as he had a strong relationship with Bella. The Cullens as a family might be divided in their opinions. Some, like Esme, might be more accepting and try to understand, while others could be more hesitant. The werewolves would also be affected. They might see this as another strange and unpredictable aspect of the vampire world and it could potentially change their relationship with the Cullens. Jacob, in particular, would probably be very confused about Bella's new situation.
In the original Twilight series, Bella's main love interest is Edward. However, in jasper hale x bella swan fanfiction, the focus shifts to Jasper. This means different character dynamics. For instance, Jasper has a different set of abilities compared to Edward, which can lead to different types of interactions and storylines. His military past in the vampire world can also bring in elements of strategy and discipline that are not as prominent in the Edward - Bella relationship.
In some fanfictions, if Bella and Jasper were mates, there would be a huge shift in the Cullen family dynamics. Jasper's ability to sense and manipulate emotions could either soothe Bella's constant emotional turmoil in a more direct way compared to Edward. It might also create jealousy and tension within the family, especially from Edward who was originally Bella's love interest. This new pairing could lead to different plotlines involving protecting Bella from vampire threats, with Jasper's combat skills and strategic thinking coming into play more prominently.
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.
Their relationship could make Edward a bit jealous. Since he's in love with Bella, seeing her have such a strong bond with Jasper might make him feel left out. Also, it could affect Alice. She's Jasper's mate, and if Bella and Jasper are very close siblings, it might change the dynamics in their group. For instance, group decisions might be influenced more by Bella and Jasper's opinions.
One way to develop their relationship uniquely is to put them in a situation where they have to protect each other's secrets. For example, Jasper might have a secret from his past as a vampire in the military, and Bella has her own secrets about her relationship with the wolves. By relying on each other to keep these secrets, a strong bond forms between them.
