In many fanfictions, Bella might be in a state of confusion about her feelings for the vampires. Jasper goes to check on her to try and understand her better. He could end up giving her some advice or just listening to her. Also, there could be a scenario where Bella is ill or injured, and Jasper, being concerned, goes to see how she is faring and if he can do anything to help her recover.
A typical situation in such fanfiction is when Bella has a secret that she's been hiding from the Cullens. Jasper, being perceptive, goes to check on her and ends up uncovering this secret. Or perhaps Bella has had a strange encounter, and Jasper is sent to see if she's been affected in any way. He may then report back to the rest of the family about what he has found.
In some fanfictions, when Jasper goes to check on Bella, he might be assessing her emotional state. For example, if Bella is in distress due to some vampire - related events, Jasper, with his ability to sense and manipulate emotions, could try to calm her down. He might also be there to protect her from potential threats, like other vampires who are not part of the Cullen family.
Another theme is the power dynamic. Jasper has his special abilities and Bella has her own charm. Fanfictions may play with how these two aspects interact and influence each other. For example, in some stories, Bella's humanity affects Jasper's view on his vampiric nature.
A prevalent theme in jasper and bella fanfiction is the struggle against the odds. They come from different backgrounds and have different natures within the Twilight universe. Fanfictions often focus on how they overcome these differences. Also, themes of loyalty and sacrifice are common. They might be in situations where they have to be loyal to each other and make sacrifices for their relationship or for the greater good of their vampire - human world.
A common scenario is that they meet during a time of crisis for their coven. Maybe there's a vampire hunter on the loose, and they come together to strategize. Another scenario could be a more light - hearted one, like at a party or gathering within the vampire community. They might share a dance and start to feel a spark between them.
One common theme is loyalty. In military - themed fanfictions about Bella and Jasper, loyalty to comrades and to a cause is often explored. For example, they might be part of a military unit where they have to trust and be loyal to their fellow soldiers in order to survive dangerous missions. Another theme could be sacrifice. They may have to sacrifice personal desires or relationships for the greater good of the military operation or the safety of their team. And transformation is also a theme. The military experience might transform their characters, making them more disciplined, courageous and resourceful.
One common theme could be the exploration of unique relationships. Maybe Jasper's'swagga' (a sort of confident and stylish attitude) creates an interesting dynamic with Bella. Another theme might be adventure, with the three characters getting involved in some sort of exciting escapade together.
One common theme is the exploration of a different kind of love. Since Jasper has his own past and Bella has her relationship with Edward in the original, their new bond in the fanfiction can show a more complex love. Another theme could be acceptance. Bella accepting Jasper's past and Jasper accepting Bella's connection to the werewolves, for instance.
Well, one could be a story where Jasper and Bella team up to solve a mystery in their small town. They might use Jasper's combat skills and Bella's intuition.
There's also 'Jasper's Redemption in Bella's World'. This fanfic delves deep into Jasper's past and how Bella helps him come to terms with it. It has a lot of emotional depth and the story is quite engaging as it shows their journey of understanding and love. It also includes some interesting twists on the vampire lore from the original series.
Another scenario could be that Bella does something that endangers Jacob's family or the werewolf pack. This would make Jacob see her as a liability and develop hatred towards her. In some fanfictions, she might accidentally expose the werewolves to their enemies because of her association with the vampires.
