Perhaps the theme could be about breaking social norms, since male pregnancy is not a common occurrence in real - life scenarios. It might also explore themes of acceptance, both self - acceptance and acceptance from others around the characters.
Well, one possibility could be that it leads to a lot of internal conflict within the group. Maybe Edward is jealous or feels betrayed. And Bella might struggle with her new situation, trying to figure out how to be a mother while still being part of the supernatural world they live in.
Bella, obviously. She is the one who is pregnant and will have to face all the physical and emotional changes that come with it. Her life will be completely turned around as she prepares to be a mother.
It could be other werewolves who oppose the union of a human and a werewolf. They might see the pregnancy as a threat to the purity of the werewolf bloodline or something against their traditional beliefs.
I'm not sure about a specific 'Jacob and Seth pregnant fanfiction'. You could try searching on popular fanfiction websites like Archive of Our Own. They usually have a wide range of fanfictions and you might be able to find something related to Jacob and Seth there.
One possible theme could be the challenges they face during the pregnancy. It might explore how their relationship changes as they deal with the situation. Another theme could be the reactions of the people around them, like their families and friends.
Perhaps there's a kind - hearted librarian who helps Jasper navigate the vast resources of the Cambridge library. A group of international students could also be main characters, with each one bringing their own unique culture and perspective to Jasper's life. And there might be a local Cambridge student who shows Jasper the hidden gems of the city.
Yes, there might be such fanfictions out there. Fanfiction often explores alternative storylines. However, this goes against the original 'Twilight' series canon which pairs Bella with Edward and has different family relationships.
