She might develop into a strong diplomat. Since she is an adopted sister, she has to prove her worth in the Stark family. So she could study the ways of different houses and use that knowledge to form alliances for Sansa. Along the way, she would also grow in confidence and become a respected figure in her own right. This development would be shaped by the various challenges and opportunities she encounters in the world of Game of Thrones.
Her character could start off as shy and unsure, but as she experiences the harshness of Westeros, she becomes more resilient. For instance, she might initially be afraid of the Lannisters, but later stand up to them.
The adopted sister's character could develop in a very different way. She could be initially overly trusting, which gets her into trouble. But this could lead to a transformation where she becomes more cynical and calculating. She realizes that in order to survive in Westeros, she needs to be more like the other power - hungry characters. This change in her character could cause some tension between her and Sansa, as Sansa might still hold onto her more noble ideals, but it would also make for a very interesting dynamic in the fanfiction.
One possibility for Sansa's adopted sister in fanfiction is that she could be a spy. Maybe she was adopted by the Starks under false pretenses, but actually sent by an enemy. However, as she grows up with Sansa, she starts to have a change of heart. She could then use her position to feed false information back to her original masters, all while protecting Sansa and the Stark family from harm.
Sansa would become more nurturing. She had a tough childhood and having an adopted daughter would give her a chance to break the cycle of cruelty she experienced. She'd be more empathetic and protective, which would make her a stronger leader as she'd be fighting not just for herself but for her daughter.
One possible plot could be that Sansa's adopted sister is from a far - off land. She might have unique skills, like being an expert archer. As the story unfolds, she could help Sansa navigate the complex politics of Westeros. Maybe she has her own secrets and motives, which could create interesting conflicts and alliances within the story.
She could be a diplomat. Given the complex political landscape in the series, Sansa's adopted sister could be trained in the art of diplomacy. She could travel to other kingdoms, forging alliances and making deals that benefit the Starks. This would be especially useful as the Starks often find themselves in need of allies.
She would become more confident earlier. Instead of being a naive girl in King's Landing, she'd use her time - travel knowledge to be assertive. For example, she'd not be easily manipulated by Cersei.
Sansa's character development in relation to the Hound in fanfic can be significant. She may start off as a naive girl but through her experiences with the Hound, she becomes more aware of the harsh realities. For instance, she might learn to be more assertive.
It develops in various ways. Sometimes, it starts with the Hound's initial gruffness towards Sansa, but as time passes, he starts to see her as more than just a Stark girl. Sansa, on her part, might begin to understand the Hound's pain and his reasons for his actions.
Their relationship could also develop in a more complex way where Sansa starts to play Littlefinger at his own game. She may start to use his own tactics of manipulation against him, leading to a shift in the power dynamic between them. It could be like a cat - and - mouse game where Sansa is slowly turning the tables on Littlefinger.
In fanfiction, Sansa's development can be greatly influenced by Sandor. She may start to question the traditional ideals of beauty and chivalry that she once held dear, seeing the realness in Sandor. Sandor himself could develop a sense of purpose beyond just being a fighter. Their interactions could be the catalyst for these changes. For instance, Sansa might encourage Sandor to use his strength for more noble causes, and in turn, Sandor could help Sansa find her true voice in a world that has silenced her for so long.
Her character might become more in tune with English magical culture. She could pick up new accents, phrases, and ways of thinking related to the English wizarding world. This would add a new layer to her personality.
