You could explore Sansa's growth from a naive girl to a strong leader. Write about her learning about different cultures and how she incorporates new ideas into ruling the North. Also, her relationship with Theon Greyjoy could be explored in terms of forgiveness and redemption rather than in a sexual context.
It's completely inappropriate. Such fanfiction objectifies the character of Sansa. 'Game of Thrones' has a rich tapestry of themes such as power, loyalty, and family. Fan creations should be in line with these broader themes and not delve into inappropriate sexual content related to the characters.
One appropriate way is to focus on her political journey. For example, you could write about how she navigates the complex political landscape of Westeros, her relationships with other political figures, and how she uses her intelligence to gain power and influence.
If Sansa was pregnant in this fanfiction, it could potentially be a catalyst for a new alliance. Jaime, despite his past actions, has certain skills and influence. This could be used to protect Sansa and the unborn child. However, they would face many enemies. The Lannisters might not accept Sansa easily, and the Northmen may be skeptical of Jaime's intentions. Sansa, on the other hand, would have to use her wits to navigate through this difficult situation, perhaps trying to use the pregnancy to her advantage in the power games of Westeros.
One interesting fanfiction could be where Sansa uses her new - found wisdom and political acumen in a situation that has a 'lemon - like' twist, perhaps in a negotiation with a difficult lord where she offers something unexpected, like a rare lemon - scented perfume from the south in exchange for loyalty. However, this is just a speculation as there are countless fan - created stories out there.
One great Sansa fanfiction is 'Sansa's Ascent'. It shows Sansa growing into a powerful leader in the North, using her wits and the lessons she's learned throughout the series. The story has a great deal of political intrigue and character development.
Theon Greyjoy can also be an interesting character to pair with Sansa. Their complex relationship can be developed further in fanfiction. Maybe Theon is trying to make amends for his past actions towards Sansa and they end up forming an unexpected alliance to face common enemies.
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.
Another plotline might involve Ramsay having a change of heart due to some unexpected event. For example, he could be haunted by his past deeds and start to treat Sansa differently. However, this would be a very complex and controversial change as he is such a cruel character. In this scenario, Sansa would have to decide whether to trust this new side of Ramsay or still seek her revenge.
Another scenario could be a more romantic one. Theon, having redeemed himself, realizes his true feelings for Sansa. They might have a moment where they share their past traumas and find solace in each other, slowly building a relationship based on mutual understanding and respect.
A possible storyline is that Sansa's pregnancy is a result of a secret love affair. The identity of the father could be a mystery that drives the plot. As she tries to keep the pregnancy a secret at first, she has to deal with the internal struggle of whether to reveal the truth or not. Meanwhile, political intrigues in the background keep the story exciting as different factions might have different interests in her unborn child.
