I'm not sure if there's a specific fanfiction where Arya is pregnant. Fanfiction is a vast world with different interpretations. Some fanfic authors might be interested in exploring this kind of relationship development and the implications of Arya being pregnant, but it might also deviate from the original tone and themes of the 'Eragon' series. You could start by looking at fanfiction archives dedicated to 'Eragon' and use relevant search terms.
In a time - travel scenario, Arya could find allies in some unexpected places. For instance, she might team up with characters from different eras. One potential ally could be a powerful sorcerer from the past who has the ability to manipulate time as well. They could help Arya understand the rules of time travel better. Another could be a long - forgotten warrior who has skills similar to Arya's. They would join forces to face common enemies in different time periods.
I haven't come across a fanfiction with that exact plot. Fanfiction often explores different relationships and storylines in the 'Game of Thrones' universe. While Arya and Jaqen have an interesting relationship, pregnancy isn't a typical aspect explored in mainstream fanfictions about them. It could be that it exists in some more niche or less well - known works, but it's not something I've seen frequently.
It might be full of drama. There could be concerns about the baby's future, like what kind of powers it would inherit. Also, it would likely change the dynamic between Eragon and Arya. They would have to deal with the responsibilities of parenthood. Maybe Eragon would become over - protective, and Arya would struggle between her duties and being a mother.
Arya and Tywin could also interact in a more unexpected way. Maybe in a situation where they are forced to work together for a short time due to some external threat. During this time, Arya has to constantly remind herself of her ultimate goal of revenge while Tywin is constantly on guard against her, yet also seeing potential in her skills for his own purposes.
In a fanfiction about Arya Stark being pregnant, she might be in a situation where she has to keep her pregnancy a secret. Maybe she's in a land where her enemies are everywhere, and if they find out, they'll use it against her. She could rely on her skills of disguise and stealth to hide her condition as she tries to find a safe place for herself and her baby.
One great Arya and Tywin fanfiction is 'The Unlikely Encounter'. It beautifully portrays the first meeting between them and how Arya's quick thinking saves her from Tywin's wrath. Another good one is 'Alliance of Convenience' which explores the idea of them working together against a common enemy. It's full of political intrigue and character development.
In Arya and Tywin fanfiction, their dynamic can be really interesting. Tywin is a shrewd and powerful figure, while Arya is a fierce and determined young girl. One aspect could be a scenario where Arya, in her quest for vengeance, crosses paths with Tywin. Maybe she tries to infiltrate his court or army in disguise. Their interactions would be filled with tension as Tywin would likely see her as a threat, yet be intrigued by her boldness. It could lead to a complex power struggle within the story.
Perhaps in the fanfiction, Arya and Jaqen form an unexpected bond due to the pregnancy. Jaqen, who is usually a mysterious and somewhat aloof character, could show a more caring and protective side. They might have to find a safe place to stay, away from the chaos of their normal lives, and figure out how to raise a child in a world full of danger and intrigue.
One possible scenario could be that Arya is captured by an enemy. Maybe she was infiltrating a stronghold and got caught, and they tape - gagged her to prevent her from using her wits and words to escape or call for help. Another situation might be that she is held captive by someone who doesn't want her to reveal certain secrets she has learned during her travels. For example, if she discovered something about a powerful family's plot, they would want to silence her quickly.
