In the fanfic, Arya could continue her journey of self - discovery at the Wall. Yoren, being more experienced, might teach her some valuable skills for survival in the harsh northern environment. They could also team up with some of the more honorable members of the Night's Watch to protect the Wall from threats, like the Others if they start to attack.
Once they reach the Wall, Arya might be seen as an oddity, a girl in a place dominated by men. But she could prove herself. Yoren could introduce her to the ways of the Wall. There might be a plot where they discover some secrets of the Wall, like hidden passages or ancient magic. They could also be part of a group that tries to unite the different factions of the Night's Watch against a common enemy.
Well, they might face many challenges at the Wall. Maybe they'll encounter wildlings and have to fight for their survival. They could also meet some of the Night's Watch members and get involved in the internal politics there.
They could meet Jon Snow. Since he's at the Wall, it's very likely. And he might befriend them or help them in some way.
Well, first off, there could be a lot of emotional turmoil. Arya is not your typical damsel in distress, so she might have a hard time coming to terms with being pregnant. Gendry would be there to support her, but there could be some clashes as they both try to figure out their new roles. For instance, Arya might not want to be coddled, but Gendry would be overly protective.
Well, it could be about Arya and Jon's adventures in the unknown lands beyond the Wall. Maybe they encounter strange creatures together, like the White Walkers, and they have to use their combined skills to survive. Arya's skills as a faceless assassin and Jon's leadership and combat abilities would surely come in handy.
Well, in a fanfic where Robb finds Arya, they could immediately start making plans to take back Winterfell. Arya's skills could be a great asset to Robb's military campaigns. They might also share stories of their experiences during their time apart, which could strengthen their bond.
Well, they might share a warm embrace. After all the hardships they've both been through, it would be a moment of pure emotion. Arya could show Jon the skills she's acquired, like her amazing swordplay. And Jon, with his leadership experience, might offer Arya some new perspectives. They could also talk about their family, reminiscing about the good old days in Winterfell.
Well, they could reunite in a moment of great danger. Maybe the White Walkers are attacking again, or there's a new enemy threatening their homeland. Their reunion would then be filled with urgency as they quickly strategize on how to defend their people. Arya might use her stealth skills, and Jon his leadership, to face the threat side by side.
In a fanfic where Arya gets captured, she might be used as a bargaining chip. Her captors could try to exchange her for something valuable, like a strategic location or a large sum of gold. Maybe they want to use her to manipulate the Starks.
Another idea for a fanfic is that Arya discovers she's not really the last Stark. There could be a long - lost relative hidden away. She then embarks on a journey to find this person. Along the way, she has to overcome many obstacles and face new enemies, all while trying to keep the hope of the Stark family alive.
In this fanfic, they might embark on a journey to explore new lands. Arya could learn more about the Faceless Men's ways from Jaquen. Maybe they'll encounter old enemies or make new allies along the way.
In the 'Arya meets Tormund' fanfiction, they might initially be cautious around each other. Arya, with her skills and distrustful nature, could view Tormund as a wild northerner. Tormund, on the other hand, would be intrigued by Arya's fierceness. Maybe they would start off as reluctant allies, forced to work together due to some common threat in the fan - created scenario. They could exchange stories of their past adventures, with Tormund's tales of the wildlings impressing Arya to some extent.
