At first, their interaction would likely be very guarded. Sansa would be cautious as she has learned to be in a world full of danger. Tywin would probably see her as a young, naive girl but also a valuable asset. As time goes on, Sansa might start to challenge Tywin's ideas, which could lead to some intense exchanges between them.
Arya and Tywin could also interact in a more unexpected way. Maybe in a situation where they are forced to work together for a short time due to some external threat. During this time, Arya has to constantly remind herself of her ultimate goal of revenge while Tywin is constantly on guard against her, yet also seeing potential in her skills for his own purposes.
One great Arya and Tywin fanfiction is 'The Unlikely Encounter'. It beautifully portrays the first meeting between them and how Arya's quick thinking saves her from Tywin's wrath. Another good one is 'Alliance of Convenience' which explores the idea of them working together against a common enemy. It's full of political intrigue and character development.
In Arya and Tywin fanfiction, their dynamic can be really interesting. Tywin is a shrewd and powerful figure, while Arya is a fierce and determined young girl. One aspect could be a scenario where Arya, in her quest for vengeance, crosses paths with Tywin. Maybe she tries to infiltrate his court or army in disguise. Their interactions would be filled with tension as Tywin would likely see her as a threat, yet be intrigued by her boldness. It could lead to a complex power struggle within the story.
At first, it could be very tense. Tywin is used to being in control and having things his way, and the Stark oc would likely have her own ideas and values. So, they might start off butting heads. But as time goes on, they could start to understand each other better. The Stark oc might see that Tywin has his reasons for his actions, and Tywin could come to respect the Stark oc's strength and integrity.
Yes, there might be some in the vast realm of fanfiction websites. You can start by checking major fanfiction platforms like Archive of Our Own. However, the content quality and nature can vary greatly.
One common theme is the clash of their different worlds. Arya is a young, vengeful girl from the North, while Tywin is a powerful, calculating lord from the Westerlands. Their interactions often explore this contrast.
There are several good ones. 'Tywin's Ascent' is a fanfic that details his rise to power. It gives a lot of background on his family and the challenges he overcame. 'The Mind of Tywin' is really interesting as it tries to get into his thought process. It shows how he made decisions that shaped the Westeros we know. And 'Tywin's Last Stand' is a fanfic that imagines his final days in a very creative way.
Character development is a key element. Writers often focus on how Aryia's vengeful side and her Stark upbringing interact with Tywin's Lannister pride and his political ambitions. For example, in some fanfics, Aryia's skills as a fighter might be pitted against Tywin's strategic mind in a tense showdown.
Power is a very common theme. Since Tywin is all about power in the original story, fanfictions often explore how he gains, maintains, or loses power in different scenarios. Family dynamics is another one. His relationship with his children, especially Tyrion, Jaime, and Cersei, is always a rich area for exploration in fanfictions.
