There could be a plot where Edward has to protect them from vampire hunters. Since he is their father, he would be extra vigilant.
One plot could revolve around Edward teaching Emmett and Jasper about the values and ethics of being a vampire. Maybe they have different ideas from him, which causes tension. There could also be a plot where they have to hide this new family relationship from the human world. And as they interact with other vampires and werewolves, their family connection might influence how others perceive them and how they are treated. This could lead to various conflicts and alliances in the fanfiction world.
A possible plot could be about Emmett and Jasper growing up with Edward as their father. They might struggle with their vampire nature while Edward tries to guide them. There could be family feuds within the Cullen family as some members might not accept this new family structure easily. And also, they could face challenges from other vampire clans who see this as an oddity in the vampire world.
There are numerous potential plotlines. For example, a story could focus on how Emmett and Jasper's relationship with their 'mother' figure (if there is one in the fanfiction) changes because of their new connection to Edward. Another could be a coming - of - age type of plot where they struggle to find their place in the family while also dealing with the challenges of being vampires. There could also be a plotline where they discover secrets about their new family heritage that Edward has been hiding. This could lead to a rift or a stronger bond between them, depending on how the story unfolds.
Yes, it can be a somewhat common trope. In many 'Twilight' - inspired fanfictions, authors like to play around with family relationships. This alteration can lead to interesting new storylines, exploring different dynamics between the characters. For example, it might change how they interact within the Cullen family and how they view their roles in relation to each other and the rest of the vampire world.
In some fanfictions, they might be portrayed as Edward's sons for the sake of creating unique family dynamics or exploring different storylines. However, this is not part of the original canon.
Another plot could be that an unexpected danger comes while they're babysitting. For example, a group of wild animals start approaching the area. Emmett is ready to fight them off physically, but Jasper uses his power to calm the animals' instincts so that they don't pose a threat to Bella. And in the process, Bella learns more about the powers of her vampire friends.
The fanfiction 'Among the Coven' is also great. It delves deep into the life within the coven that includes Edward, Emmett, and Jasper, and how Bella fits into this world. It has great character development and the plot keeps you hooked from start to finish.
One interesting fanfiction could be about an alternate universe where Bella has to choose between Edward and Jasper in a more complex situation involving Emmett as a mediator. In such a story, the dynamics between the characters can be explored in depth, with their different personalities and abilities coming into play.
Jasper would probably be more responsible. He has a more calm and collected nature. He's used to thinking things through and controlling situations, which would be really useful when babysitting. For example, he would be the one to make sure Bella eats her meals on time and goes to bed at a proper hour.
One possible reason could be that Bella discovers a different side of Jasper that she finds more appealing. Maybe Jasper shows a deeper understanding of her in some aspects that Edward lacks. For example, Jasper's past experiences might make him more empathetic towards Bella's own struggles in a way that Edward, with his own set of vampire characteristics, doesn't quite get.
One interesting plot idea could be a love triangle where both Edward and Emmett are vying for Bella's attention in a more complex way than in the original story. Maybe there are external forces at play that make Bella question her feelings for both of them.
Maybe they love adventure - themed fanfiction. In such stories, they could embark on exciting quests, face dangerous enemies, and discover new worlds.
