Many fanfics play with the idea of prophecy. Since both Jon and Daenerys have elements of prophecy surrounding them in the original story, fanfics can expand on this. For example, they might be the key to fulfilling a greater prophecy together that could save Westeros in a way that goes beyond just defeating the White Walkers. Their relationship can also be a catalyst for changes in the political and social structure of Westeros, with some fanfics delving deep into how they influence the different regions and houses.
There are fanfics that explore a world where Jon Snow is sent to Essos as an envoy to Daenerys before she even sets sail for Westeros. This could involve a lot of political intrigue as they try to figure out if they can trust each other. Their relationship could develop in a more gradual and complex way as they navigate the power dynamics between different factions in Essos.
Another great one is 'Frozen Fire'. Here, the story takes a different turn after the Battle of Winterfell. Daenerys and Jon, instead of the tragic end in the series, find a way to reconcile their differences. They start to build a new Westeros together, with their love for each other becoming a symbol of hope for the people. Their relationship is depicted as a force that can heal the war - torn land.
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 a scenario where they meet under different circumstances. For example, if Jon Snow was born a female and was sent to Essos instead of the Wall. Their first encounter there could lead to a whole new set of adventures and a unique relationship. This would involve exploring different cultures and power dynamics between them. It could be really interesting as they both have different leadership styles and goals, and seeing how they merge or conflict in a new context is exciting.
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 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.
A frequent theme is the idea of a united Westeros. Fanfics usually show that through their relationship, Jon and Daenerys can bring together the North and the rest of the kingdoms. Also, the theme of destiny is common. They are seen as two important figures whose paths were meant to cross, and fanfics explore how this plays out in their relationship.
There might be a fanfiction where Dark Jon Snow and Daenerys meet in a different scenario, like on a diplomatic mission. Jon, with his changed personality, tries to manipulate Daenerys for his own ends. However, Daenerys is no fool and she sees through his games. This leads to a power struggle between them that is full of political intrigue and personal drama.
One interesting fanfiction could be where Daenerys and Jon Snow team up to fight a new, unexpected threat in Westeros that is even more powerful than the Night King. In this story, they combine their unique skills and the power of their dragons to protect the realm.
One interesting fanfiction could be about their journey together after they first meet. Maybe they team up to fight a new, unexpected threat in Westeros that wasn't in the original series. They combine their forces, Jon with his knowledge of the North and Daenerys with her dragons and army.
