One common theme is redemption. The Hound has done some bad things in the show, and many fanfictions focus on his path to redeem himself, whether it's through acts of kindness or finding a new moral code.
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.
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.
One interesting scenario could be Sansa and the Hound meeting again after a long time apart. Sansa has grown stronger and more self - assured, and the Hound is still his gruff self. They might have a conversation where Sansa stands up to him in a new way, showing how much she has changed since they last interacted.
You can start by exploring his past traumas more deeply. For example, his relationship with his brother. By delving into those memories, you can show how they still affect his present actions and decisions.
One idea could be the Hound's journey after leaving King's Landing. He could encounter a group of outcasts and form an unlikely alliance to protect a small village from raiders. It would show his growth from a bitter, angry man to a more empathetic protector.
In some fanfiction, Arya and the Hound might have a heart - to - heart conversation about their pasts. The Hound could open up about his troubled childhood, and Arya could share her experiences in the House of Black and White. This would deepen their bond in a more emotional way.
Another one is 'The Hound and the North'. It places the Hound in the context of the North, interacting with the Northern lords and warriors. It gives a fresh perspective on his character as he adapts to the different culture and challenges of the North.
The Sansa - the Hound dynamic in fanfic often explores themes of redemption and unexpected alliances. The Hound, with his damaged past, is drawn to Sansa's innocence. Sansa, on the other hand, is in a world where she needs any form of protection she can get. Their interactions can range from tense stand - offs to moments of deep understanding.
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.
