Well, in some fanfictions, the baby could be a symbol of hope. As Jon and Daenerys' child, it represents the union of two powerful houses. The baby might grow up to be a great leader, trained in both the ways of the Targaryens and the Starks. It could bring about new laws and a more just society, learning from the mistakes of the past rulers in Westeros.
Some fanfictions might explore the idea of the baby facing threats from those who oppose the union of Jon and Daenerys. Enemies could see the baby as a threat to their own power-hungry plans. So, there could be a story where the baby has to be hidden and protected. And as it grows, it discovers its true identity and fights for its rightful place in Westeros.
One idea could be that the baby is born with a special ability, like being able to communicate with dragons even more so than Daenerys. Maybe the baby's presence unites the remaining kingdoms in a way that Jon and Daenerys alone couldn't. Another thought is that the baby becomes a symbol of hope for a new era, with people from all over coming to see the new heir of the Targaryen - Stark line.
One interesting idea could be the political implications of their baby. Since Jon and Daenerys both have claims to the throne, their child would be a powerful heir with a complex lineage. Another idea might be the cultural impact. Their baby could symbolize a union between the North and the Seven Kingdoms, bringing different traditions together. Also, the baby could be a key factor in uniting the remaining factions after the great war, as it represents a new hope and a future for the war - torn land.
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.
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.
Another fanfiction concept could be a 'what if' scenario. What if Jon was the one who found Daenerys when she first landed in Westeros? This would put Jon in a position of power and knowledge about this new queen. He could act as her guide through the complex web of Westerosi politics. Their relationship might develop more organically as he helps her navigate the land he knows so well, and perhaps they would fall in love more gradually, away from the prying eyes of the other lords and ladies.
One idea could be a story where Aemon grows up in a world trying to heal from the previous wars. He has the combined traits of Jon and Daenerys, being both strong - willed like his mother and having a sense of honor like his father. He could be on a journey to discover his own place in this new world, facing challenges from those who still hold grudges against his parents' union.
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.
Tyrion Lannister could be involved. He was close to Daenerys and had a relationship with Jon as well. He might be the one to help protect the baby or offer his wisdom in raising the child. Another character could be Ser Davos. He was loyal to Jon and would surely be interested in safeguarding the future of Jon's heir.
One idea could be the baby growing up with unique powers due to the combined bloodlines. Maybe the baby has an uncanny ability to communicate with dragons from a very young age, like it has a special bond with them. Another plot could be about the challenges of raising a child in a world full of political intrigue and power struggles. The baby might become a target for those who fear the growing power of Daenerys and her family.
One interesting plot development could be that after the kiss, they face opposition from their respective advisors. Jon's men in the North might think he's being swayed by Daenerys' power, while Daenerys' council could worry about her getting too involved with a Northern leader. This could lead to internal strife within both of their camps.
