I'm not sure if there is a specific 'Jacob gets Renesmee pregnant' fanfiction. Fanfiction can cover a vast range of ideas, but this is a rather controversial and unusual plot. It might exist in some corners of the fanfiction world, but it also goes against some of the original concepts in the source material. You would need to search through various fanfiction platforms like Archive of Our Own or FanFiction.net to find out for sure.
One possible plot could be the challenges they face in their relationship due to the unexpected pregnancy. For example, how they deal with the reactions from their families and friends in the Twilight universe. Another plot might involve the preparations for the new life, like finding a safe place to stay.
The implications would be significant. First, it would change the entire perception of the characters. Jacob and Renesmee's relationship has certain boundaries in the original. This fanfiction concept would break those boundaries and create a whole new set of relationships and family dynamics. It might also face a lot of criticism from the fan community for straying too far from the source material. Additionally, it could raise ethical questions about the nature of the relationship depicted in the fanfiction, as Renesmee has a unique origin in the original story.
It could include how the other characters react. For example, Bella and Edward might have mixed feelings. Also, it could show how Jacob and Renesmee prepare for the new arrival. Maybe they would have to deal with the differences between their species while raising a child.
One possible plot could be the challenges they face as a young couple expecting a baby. Maybe they struggle with telling their families, especially considering the unique nature of their relationship in the fanfiction world. Another could be how they prepare for the baby, like finding a place to live and getting things ready for the new arrival.
One of the main supporting characters could be Bella. As Renesmee's mother, she would likely be very involved in the pregnancy, offering advice and support. Another could be Edward. He might have some concerns about the situation but also be there to help protect the family. Alice could also be a key supporting character, perhaps using her gift to foresee any potential problems during the pregnancy.
One possible reason could be that Renesmee simply has different interests. Maybe she is more drawn to a different lifestyle or set of values that Jacob doesn't align with. For example, she might be interested in exploring the world in a more solitary way while Jacob is more about the pack and community.
Another reason could be to protect her from a prophecy. In the world of fanfiction, there could be a prophecy that foretells Renesmee's doom if she stays with the Cullens. So Jacob, thinking he's doing the right thing, kidnaps her to keep her away from that fate.
They are a popular couple in fanfiction because their relationship in the original Twilight series is quite complex and full of potential. Their age - difference - like situation (Jacob being older in a way) and the fact that Renesmee is a half - vampire half - human make for an interesting dynamic that fanfiction writers love to explore.
Yes, it is quite popular among Twilight fans. Many fans are intrigued by the unique relationship between Jacob and Renesmee. Their story in the original series had elements that left room for fanfiction exploration, and fans enjoy creating and reading different scenarios of their possible romance.
