Well, Tyrion (if he is part of this fanfiction) might see it as an opportunity to manipulate the situation to his advantage, given his own cunning nature. Cersei, if she gets wind of it, would be furious and try to find a way to get rid of Sansa and the unborn child. Jaime would have to stand up to his sister to protect Sansa, which would be a huge character development for him as he breaks away from his sister's influence more completely. Sansa would also have to grow stronger and more assertive, using her wits to survive in this new and dangerous situation.
Jaime could be torn between his loyalty to his family (if we consider the complex family dynamics in the original story) and his new - found responsibility towards Sansa and the unborn child. He might try to find a way to make things right in his own way. Sansa would start to think about how this affects her political standing and her relationships with other characters. She may seek out allies who can help her through this difficult time, all while dealing with the emotional turmoil of being pregnant in such strange circumstances.
The Stark family would likely be horrified at first. Sansa's father was beheaded by the Lannisters, and there is a long - standing feud between the two houses. Her brothers, if they were alive, would be very angry and might see it as a betrayal. The Lannisters, on the other hand, would also have a mixed reaction. Cersei would probably be furious, seeing it as a threat to her power and influence. Tyrion might be more understanding and could potentially try to mediate between the two families.
One possible plot could be that Jaime is forced into a situation where he has to protect Sansa, and during that time, some false accusations are made that Sansa is pregnant with his child. This then leads to a chain of events where they have to work together to clear their names and also deal with the power struggles around them.
Sakura would probably be very shocked and disappointed in Naruto. She has always had deep feelings for him. Kakashi might be more level - headed, trying to figure out how to handle the situation from a strategic and diplomatic point of view.
The other gods would have mixed reactions. Some might be amused or see it as an opportunity to gain an advantage. For example, Hera, Zeus's wife, would be extremely angry and might seek revenge on Annabeth. The other demigods would be divided. Some might pity Annabeth, while others might see her as having overstepped or being too ambitious. The child, if it was born, would be a source of both hope and fear for different characters. It could be seen as a powerful ally or a dangerous threat depending on who you ask.
Gohan would likely be extremely shocked and angry. He is Pan's father and would have a hard time accepting this situation. Vegeta might be disappointed in Trunks, as it goes against Saiyan propriety. Bulma would probably be worried about the implications for the family and how to handle the situation. Goten might be confused and not know how to react, as it involves his nephew and niece in a very unexpected way.
Percy would probably be extremely confused and worried at first. He's a hero, but this is a situation he's never faced before. He might feel a sense of responsibility towards Artemis and the unborn child. Artemis, on the other hand, would be in shock. As a virgin goddess, this goes against everything she stands for. She might initially be angry, but then start to think about how to handle the situation in a way that doesn't disrupt the order of the gods too much.
Harry would probably be in a state of shock and disbelief at first. He'd be filled with a mix of fear, confusion and anger. Voldemort might be initially dismissive or see it as an opportunity to further his own dark plans. Hermione would be practical, trying to find solutions in books and magic. Ron would be more likely to be openly disgusted at first but might come around to support Harry as a friend.
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.
Yes, there might be some. Some fanfiction writers focus on creating non - explicit, family - friendly stories. They could explore the idea of Jaime and Sansa in a more platonic or AU (Alternate Universe) context where a pregnancy is part of a story that doesn't involve adult content. For example, in an AU where they are part of a political alliance and a pregnancy is a strategic move in a game of thrones - like political scenario.
The characters' reactions would be diverse. Harry, being the main character, would likely feel a great sense of responsibility. He'd have to face the judgment of both the wizarding community and the vampires. Hermione would be her usual studious self, looking for any precedents or magical knowledge to help. Ron would probably voice his concerns loudly, thinking it's a dangerous and strange situation. The vampire involved would have her own emotions, perhaps a mix of fear and hope for the future. And other vampires in the community could range from being supportive to being hostile depending on their beliefs and positions within the vampire hierarchy.
