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 idea could be Arya using her Faceless Man skills to avenge the wrongs done to her family. She could infiltrate the enemies' strongholds unnoticed and take them out one by one.
One idea could be a crossover where Naruto is transported to the world of Westeros. He meets Arya Stark and they team up. Naruto could teach Arya some of his ninja skills, like how to move stealthily like a shinobi. This would enhance Arya's ability to seek revenge on her enemies in a more efficient way.
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.
Yes, there are likely fanfictions out there with such a plot. Fanfiction writers often come up with creative and sometimes out - of - the - box ideas. However, these are not part of the official 'Game of Thrones' storyline. It's a way for fans to explore different 'what - if' scenarios and relationships that they might have wanted to see in the series.
Arya might use her pregnancy as a form of strength. Instead of seeing it as a weakness, she could turn it into a motivation to create a better world for her child. She could start training a new generation of fighters, including her unborn child in her plans for a more just and peaceful Westeros.
One possible storyline could be the secrecy and the initial shock of both Arya and Jon. They would have to figure out how to deal with this situation in a world full of political intrigue and family expectations. Another could be the reactions of their families. The Starks might be divided on how to handle this unexpected event, and it could create internal conflicts within the family. Also, the implications for the power dynamics in Westeros could be explored, as a child of Arya and Jon could potentially have a claim to the throne.
Perhaps Arya discovers she's pregnant while on a journey with Jaquen. They then have to make decisions about their future. Do they continue their nomadic lifestyle? Or do they find a place to settle down? And there could be internal conflicts within Arya, as she's always been a fighter and now has to embrace a new role as a mother - to - be.
One plot idea could be that Arya and Aegon meet during their travels. Aegon, with his claim to the Iron Throne, is in need of a skilled ally like Arya. She could help him in his political maneuverings in a way that no one else can, using her skills of disguise and stealth. Another could be a story where they are forced to team up against a common enemy, like a new threat rising in the Seven Kingdoms that neither the Starks nor the Targaryens can face alone. They start off distrustful of each other but gradually come to respect and rely on one another.
One plot idea could be Arya and Jon teaming up to uncover a long - hidden family secret. Maybe there's a lost Stark heirloom that has some sort of power, and they have to go on a quest to find it. Another idea is that they are both sent on a diplomatic mission to an unfriendly kingdom, and they have to use their unique skills - Arya's stealth and Jon's leadership - to succeed.
One plot idea could be Arya, in disguise, getting close to Tywin as a servant in King's Landing. She could overhear his plans and use that knowledge to try and undermine the Lannisters from within. Another could be a scenario where Tywin discovers Arya's true identity but decides to keep her alive for some strategic reason, perhaps to use her as a bargaining chip against the Starks. And a third idea might be a story set in an alternate universe where Arya and Tywin form an unlikely alliance against a common, greater threat, like a White Walker invasion in the south before the events at the Wall.
