Well, it could start out very tense. Ramsay is cruel and Sansa is a victim. But with the presence of a baby, Ramsay might start to show some unexpected softness towards Sansa. He may not be as violent as he used to be towards her.
The relationship could also develop in a very dark way. Ramsay might see the baby as a tool to further torment Sansa. He could threaten to harm the baby if she doesn't do as he says. Sansa, on the other hand, would be constantly in a state of fear and trying to find a way to protect the baby and herself from Ramsay's insanity.
Sansa would likely become more determined and resourceful. The pregnancy would force her to think not just about her own survival but also about the life growing inside her. She'd have to be stronger to face Ramsay's madness.
One possible plot could be a story where Sansa manages to escape Ramsay's clutches before any harm comes to the baby. Maybe she finds allies within the castle who help her flee with the baby to a safe place, like a hidden forest village.
Sansa could grow in terms of her resilience. The pregnancy in such a terrible situation with Ramsay would force her to become stronger. She would have to find ways to protect not only herself but also the unborn child, which could lead to a more hardened and strategic Sansa.
One common theme is survival. Given Ramsay's brutality, Sansa often has to fight for her life, either physically or psychologically. For example, in many fanfictions, she uses her knowledge of courtly intrigue to stay alive. Another theme is power struggle. Ramsay wants power over Sansa, and she resists, leading to a constant back - and - forth.
Often, these fanfictions involve a re - imagining of their relationship. They might give Ramsay a more redeemable quality, which is different from his cruel nature in the original story. For Sansa, her strength and growth are usually emphasized as she navigates this new relationship.
One possible plot development could be Sansa trying to escape with the unborn child to protect it from Ramsay's cruelty. She might seek help from old allies or find a hidden place to hide until the baby is born.
Their relationship could be explored by focusing on Ramsay's insecurities. Maybe Ramsay is actually secretly in love with Sansa in a very twisted way, and his abuse is a result of his inability to handle his feelings. Sansa, on the other hand, could try to use this knowledge to manipulate him.
One common theme is survival. Sansa has to find ways to survive Ramsay's brutality. Another theme is power struggle. Ramsay has power over Sansa, and she tries to regain some sort of control. Also, there's the theme of redemption in some fanfictions where Ramsay might show a glimmer of humanity or Sansa finds a way to forgive, though this is less common given Ramsay's character.
One great Sansa and Ramsay fanfiction is 'A Different Path'. It explores an alternate universe where Sansa manages to outwit Ramsay in a more psychological battle rather than a physical one. The author does an excellent job of delving into Sansa's character growth in the face of Ramsay's cruelty.
There might be some out there that are more appropriate. Some fanfictions might focus on the psychological and emotional aspects of Sansa's situation without delving into inappropriate content. You could try searching on family - friendly fanfiction platforms.
