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.
Often, Sansa is portrayed as a powerful figure in fanfiction, and Jaime's character can add an interesting dynamic. They might be shown as having conversations that never occurred in the show. For example, Jaime could offer Sansa his insights about the political situation in King's Landing, which she could use to her advantage in her own political maneuvers in the North.
There are also fanfictions where their relationship takes a more romantic turn. This can be controversial as in the original series, their interactions were not of that nature. However, in the world of fanfiction, writers explore the idea of them finding solace in each other. Jaime's honor (or his new - found sense of it) and Sansa's grace could be seen as complementary, leading to a relationship that defies the expectations of the original Game of Thrones narrative.
It could be about Jaime and Sansa fulfilling a vow within the context of the 'Game of Thrones' universe. Maybe it's a story where Jaime has made a vow to protect Sansa, and the fanfic details how that vow is carried out. It might involve political intrigue, battles, or personal relationships as seen in the original series.
A pregnancy for Sansa in relation to Jaime would completely shift their story arcs. For Jaime, it could be the ultimate test of his new - found moral compass. He has already broken away from some of his family's more cruel ways, and this would be another step in that journey. For Sansa, it would add another layer of vulnerability and strength. She has grown from a naive girl into a strong woman, and a pregnancy would force her to be even more resilient. It could also lead to some interesting interactions with other characters, like Tyrion who has his own complex relationship with both Jaime and Sansa.
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.
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.
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.
One possible plot could be about how Jaime has to face his complex family dynamics when Sansa is pregnant. He might struggle with how his sister Cersei would react and also deal with the political implications in Westeros.
Another option is to check out some dedicated 'Game of Thrones' fan communities on social media platforms like Reddit. There are often threads where fans share and discuss their favorite fanfics. You might be able to get a link or more information about where to find this particular fanfic from other fans in those communities.
Another possibility is that the father could be a new character introduced in the fanfiction. This new character could be a powerful lord from a far - off land who comes to Winterfell, falls in love with Sansa, and they have a relationship. Or perhaps it's a mysterious figure with magical powers who impregnates Sansa as part of a grander scheme in the magical and political landscape of Westeros.
