At first, it could be a teacher - student relationship, with Jaqen teaching Arya more advanced skills of the Faceless Men. As time goes on, they might become comrades, relying on each other in dangerous situations.
It's possible that they would go on a mission to uncover some long - lost secrets in the world of 'Game of Thrones'. Jaqen's knowledge of the underworld and Arya's determination could lead them to places like the ancient Valyrian ruins. There, they might find powerful artifacts or knowledge that could change the balance of power in Westeros.
Arya may become more confident in her abilities with Jaqen's guidance. She could grow from a somewhat reckless girl into a more calculated and strategic assassin. For example, she might learn to better plan her attacks instead of acting on impulse all the time.
Jaqen's mysterious nature makes him badass in fanfics. He doesn't reveal much about himself or his motives. Writers can play with this mystery, and readers are always left guessing what he'll do next. Also, his loyalty to certain things or people, when it shows up in fanfics, adds to his badassery.
One great Jaqen fanfic is 'Jaqen's Redemption'. It explores his character in more depth and gives him a backstory that wasn't fully explored in the show. Another one could be 'Jaqen and the Hidden Paths' which delves into his mysterious ways and the paths he might have taken outside of what we saw in the series.
In some fanfictions, there might be a plot where Jaqen actually has a deeper connection to Arya's family than she initially realizes. Maybe he was secretly tasked with protecting her all along. This could lead to a series of revelations and a change in their relationship dynamics, from mentor - student to something more like comrades in a grander scheme.
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.
One possible adventure is that they get involved in a heist. Maybe there's a valuable item in a heavily guarded castle, and they plan to steal it. Jaquen could use his skills of disguise and Arya her quick thinking to pull it off. Along the way, they'll face guards, traps, and other obstacles. This adventure would not only be about getting the item but also about their growth as a team.
Yes, there will likely be more. 'Game of Thrones' has a huge and passionate fan base. Even though the show has ended, the rich world created by George R. R. Martin continues to inspire fans. New readers are constantly discovering the books and the show, and this influx of new fans often leads to more fanfiction. Additionally, there are still many untold stories and character arcs that fans love to explore in their own writing.
In regular 'Game of Thrones' fanfic, the storylines can be quite diverse, following the main plot arcs of the show or creating new ones that are not so extreme. But in bondage fanfic, it usually involves some form of restraint or captivity, which limits the characters' physical freedom. This leads to different character developments. In regular fanfic, a character might grow through political intrigue or personal relationships, while in bondage fanfic, they may grow through dealing with their lack of freedom and the associated challenges like escaping or surviving in a confined situation.
