One scenario could be that Jon and Daenerys meet earlier in their journeys. Maybe Jon, while on an expedition beyond the Wall, stumbles upon Daenerys and her dragons in Essos. They form an immediate bond over their shared sense of justice and leadership. Daenerys is intrigued by Jon's loyalty to his people in the North, and Jon is in awe of her power and determination.
Another fanfiction idea could be a scenario where Jon and Daenerys are forced to marry for political reasons, much like in the realpolitik of the Game of Thrones world. At first, they are hesitant and a bit hostile towards each other. But as they get to know each other better, they start to fall in love. They then use their combined influence to bring about a more just and peaceful rule in Westeros, reforming the old feudal system.
In some fanfictions, they might face a common enemy together that is even more powerful than the White Walkers. This enemy could be a powerful sorcerer who is trying to take over both Westeros and Essos. Jon and Daenerys would have to combine their military strategies, Jon's knowledge of the North and Daenerys' experience with different cultures and her dragons, to defeat this new threat.
One interesting plotline could be their joint quest to defeat the Night King. They combine their forces, both the Unsullied and Dothraki with the Northmen. Their relationship also evolves during this time, from initial distrust to a deep mutual respect and perhaps something more romantic. They learn from each other's leadership styles and together become a formidable force against the undead threat.
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.
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.
One interesting scenario could be their first encounter. Maybe Jon arrives at Daenerys' court as an envoy from the North. Their initial meeting would be filled with tension and curiosity. Jon, a man of the North, and Daenerys, the would - be queen with her dragons, would size each other up. Another scenario could be them fighting together against a common enemy, like the White Walkers. They would combine their forces, Jon with his knowledge of the North and Daenerys with her powerful dragons and army. And a third scenario might be a more personal one, where they gradually fall in love during their journey together, sharing their dreams and fears.
One interesting plotline could be them uniting the kingdoms without the bloodshed that occurred in the show. They might use their combined influence and the respect people have for them to bring about peace. For example, Jon's connection to the North and the wildlings, along with Daenerys' army and dragons, could be used to defend all of Westeros against a common enemy like the White Walkers that they both faced in different ways in the original story.
One interesting scenario could be Daenerys and Daario going on a secret mission together. They might have to infiltrate an enemy stronghold, relying on each other's skills. Daario's combat expertise and Daenerys' ability to command and strategize would make for an exciting adventure.
One interesting scenario could be a story where Daenerys and Drogo face a new, unknown threat together. Maybe a strange disease starts spreading in their camp, and they have to work together to find a cure, relying on Daenerys' intelligence and Drogo's leadership. This could show a different side of their relationship, more about cooperation in the face of danger.
One interesting fanfiction could be where Jon and Daenerys form an alliance much earlier and together they face the White Walkers. They combine their forces and knowledge, with Jon teaching Dany about the North and its ways, and Dany sharing her dragon - riding skills with Jon. This could lead to a more united front against the common enemy.
One interesting scenario could be Dany and Jon teaming up to fight a new, unknown threat that emerges in the North, something more powerful than the White Walkers. They combine their forces and unique abilities, like Dany's dragons and Jon's leadership skills.
One interesting scenario could be Jon and Dany teaming up to fight a new, unknown threat that emerges in the East of Essos. They combine their military strategies, with Jon's knowledge of the North and Dany's experience with her Unsullied and Dothraki forces.
