A plot twist might be that Daenerys and Jon Snow find out that the pregnancy is not a normal one. It could be that the child has some sort of special powers or abilities even before birth. This could lead to various factions either trying to protect or destroy the unborn child. Also, there could be a twist where the pregnancy causes a rift between them because they have different ideas on how to raise and protect the child in a world full of danger and political unrest.
One interesting plot twist could be that when they meet, they find out they are related much earlier than in the original series. This would completely change the dynamic between them, especially if there were any romantic undertones developing. Another twist could be that Daenerys initially refuses to help Jon against the White Walkers because she believes it's a ploy by the other Westerosi lords to weaken her. Or perhaps Jon discovers a secret about Daenerys' dragons that makes him question her true intentions.
One possible plot twist could be that they immediately recognize each other as allies against a common enemy. They might join forces right away and start planning their strategies. This would be different from the show where they had some initial hesitations.
Well, perhaps there's a plot twist where they take the Iron Throne but then realize it's a false victory. There could be a shadowy organization behind the scenes that has been manipulating events all along. This organization could then try to undermine their rule. Also, what if the throne itself has some sort of mind - controlling power? It could start to influence Jon and Daenerys in unexpected ways, leading to a rift between them.
Well, a possible plot could be that they marry in a grand ceremony that combines the traditions of the North and the Targaryen customs. Then, they embark on a journey to bring peace to all the kingdoms. They face challenges like rebellious lords who don't accept their rule. But with their dragons and the loyalty of the Northmen, they gradually gain the upper hand. Also, their marriage could lead to a new era of magic in Westeros as their combined bloodlines might unlock some hidden powers.
One possible plot twist could be that Tyrion discovers a secret about Daenerys' past that threatens their relationship. Maybe she has a hidden alliance or a family secret that could change everything. Another could be that political enemies try to use their marriage as a way to undermine them, forcing them to fight not only for their love but also for their thrones.
Maybe the pregnancy is a difficult one. Daenerys, being a strong - willed woman, tries to hide her pain and weakness from her subjects. Jon, on the other hand, is overly protective. This causes some friction between them as Daenerys wants to continue ruling as normal, while Jon wants her to rest. Meanwhile, rumors spread across the kingdoms about the nature of the baby - is it a normal human or something more? And this leads to all kinds of superstitions and unrest.
In a possible plot, it could be that Daenerys has started to show signs of tyranny even while pregnant. Jon, being a man of the people and with a strong sense of justice, might feel that he has no other choice but to stop her. However, this act would be extremely controversial as she is pregnant. It could also lead to a civil war of sorts, with different factions taking sides based on their loyalty to either Jon or Daenerys. Her death could also have unforeseen consequences, like the unborn child having some sort of prophetic or powerful significance that is now lost, causing chaos in the world of the story.
One possible plot could be that Jon Snow, on his journey north of the Wall, somehow gets lost or is magically transported to where Daenerys is. They immediately recognize each other's importance. Jon, being the honorable man he is, offers his help to Daenerys in her quest for the Iron Throne. Daenerys, in turn, is intrigued by Jon's tales of the North and the White Walkers. They form an alliance early on, which changes the course of the entire Game of Thrones story, with their combined forces being a formidable power in Westeros.
One common theme is the struggle for power. With a baby on the way, they have to consider how this new addition will affect their claim to the Iron Throne. Another theme is love and family. Their relationship deepens as they prepare for the arrival of their child.
Well, in some fanfics, a plot twist could be that the pregnancy was a result of some sort of magic or prophecy manipulation. So, instead of it being a natural occurrence, it was part of a grand scheme. This could lead to a lot of self - discovery for Jon and Daenerys as they figure out what it all means and who was behind it. Also, the twins might have some sort of connection to an ancient evil or a long - lost power, which would add a whole new layer of mystery and danger to the story.
