In some fanfictions, there could be a plot where Arya disguises herself and infiltrates an enemy camp, and Jon, with his knowledge of the politics and military, devises a plan to rescue her. Their bond as siblings is further strengthened through such adventures.
One interesting storyline could be Jon and Arya reuniting after a long time apart and teaming up to take on a new threat in the North. They might use their unique skills, Jon's leadership and Arya's assassin training, to protect their home.
In some fanfictions, there could be a story where Arya and Jon discover a long - lost family secret that changes their understanding of their heritage. This could involve some sort of magical or political revelation that binds them closer together and gives them a new mission. For example, they might find out that there is a hidden power in their bloodline that can save Westeros from a greater danger.
One interesting storyline could be them uniting the kingdoms in a different way than in the original series. Maybe they find a way to combine their different leadership styles and bring about a more peaceful and prosperous Westeros. For example, Dany's experience with ruling different cities and Jon's knowledge of the North could create a unique form of governance.
One interesting storyline could be Jon and Sansa ruling Winterfell together in a more harmonious way than in the show. They could face challenges from the remaining enemies in the North and strengthen their bond through mutual respect and strategic planning.
Jon Snow is often very well - written. In fanfiction, his complex personality, torn between his Stark upbringing and his Targaryen heritage, can be explored in great depth. His sense of honor and duty is a central part of many stories.
In some fanfictions, there might be a plot where Robb discovers Arya's true potential in a different way. Maybe he sees her combat skills and decides to train her further, creating a unique bond between them as they both strive for the survival of their family. This could involve them facing off against common enemies and making strategic decisions together.
One great Arya and Jon fanfiction is 'The North Remembers'. It shows a unique bond between them as they face the challenges in the North together. It has some really interesting plot twists and great character development.
I would recommend 'Jon and Arya: The Reunion'. This fanfiction is short but sweet. It focuses on the emotional moment when they finally see each other again. It doesn't get into a lot of complex plotlines but rather just gives you that warm feeling of their sibling love.
Attention to detail. The world of Game of Thrones is rich in detail. A great Arya and Jon fanfiction will include details about the setting, the politics, and the culture. For instance, if they are in Winterfell, it should describe the castle, the people there, and how their actions are affected by the politics of the North. This helps to immerse the reader in the story and makes it feel like a real part of the Game of Thrones world.
One interesting storyline could be Arya traveling to a far - off land not mentioned in the original series and using her skills to become a legend there. Maybe she discovers a new form of combat that she then brings back to Westeros.
In some fan fictions, Arya might have an encounter with the Faceless Men again, but this time not as a student but as an equal or even a leader. She could use their skills to take on a powerful and corrupt regime in Westeros.
