Another possibility is that Arya is betrothed to a younger son of a powerful Westerosi house. This son might be overlooked in his own family but has great potential. Arya's betrothal to him could be a strategic move by his family to gain an edge, and for Arya, it could be a chance to infiltrate and disrupt the power structure of that house from the inside.
She could be betrothed to Gendry. Since they have a history together, it would be an interesting dynamic. Gendry is a strong and capable man, and their union could bring together different aspects of Westeros, the common folk represented by Gendry and Arya's more noble - yet - rogue upbringing.
Maybe she's betrothed to a character from Essos. This would open up new storylines and cultural exchanges. For instance, a wealthy merchant prince from one of the Free Cities. His wealth and Arya's skills could make for an exciting combination. They could form an alliance to gain more power and influence in both Westeros and Essos.
In some fanfictions, Arya could be betrothed to Gendry. They have a connection in the original series, and fans might imagine their relationship developing further into a betrothal. It would be an interesting match as they both have a sense of independence and a rough past.
In some fanfics, Arya's betrothal might lead to her learning new courtly manners. For example, she could be betrothed to a noble from a far - off land. This would force her to adapt to different cultural norms, which is a huge change from her assassin - training days. She might struggle with the idea of being a lady but also use her skills to navigate the political intrigue that comes with such a union.
Arya Stark is one of the most beloved characters from 'Game of Thrones'. She is initially presented as a bit of a tomboy, not conforming to the ladylike standards of her society. As the story progresses, she becomes a key player in the power struggles of Westeros. She is brave, resourceful and has a very distinct personality that makes her stand out among the many characters in the series.
There are fanfics that focus on their relationship evolving over time. For example, after all the hardships they've faced, they start to truly understand and support each other. Sansa helps Arya adjust to the more courtly life when she returns, while Arya teaches Sansa some self - defense skills in case of future threats.
The twin could be a long - lost relative of Arya. Maybe they are from a branch of the Stark family that was thought to be dead or lost. This would add an interesting layer to the story as they would share some of the Stark blood and loyalty.
One possible plot could be Arya using the brothel as a cover. She might be spying on certain characters who frequent the place. Since she has skills in disguise and stealth, she could blend in among the workers or patrons to gather information for her own purposes, like revenge or to aid in the political chaos of Westeros.
Another type of antagonist could be a dark sorcerer. This sorcerer might be after Arya for her unique skills or because she has something that he wants. He could use his magic to create all sorts of obstacles for Arya and the Hound, like summoning demons or casting illusions to mislead them.
In a fanfic, Arya could be in the brothel to rescue someone. It could be a young girl who was sold into prostitution against her will. Arya, with her skills and no - nonsense attitude, decides to take matters into her own hands. She has to outwit the brothel owner and any guards, and this adventure in the brothel could be a new chapter in her journey of self - discovery and growth as a character.
A great plot twist would be if Arya's gag was part of a larger scheme by the Faceless Men. They could be testing her in a new and extreme way. Maybe they want to see if she can still carry out her assassinations without being able to speak or use her normal methods. This would put her skills and training to the ultimate test.
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.
