A simple way is through shared goals. Since they all support Aegon's claim, they gradually build respect for each other. For example, Barristan may initially be skeptical of Jon Connington's past actions but as they work together towards Aegon's ascension, he comes to understand and respect him.
One idea could be a story where they are all on a quest to reclaim the Iron Throne for Aegon. Jon Connington could be using his military knowledge, Jorah his loyalty and experience, Barristan his honor and combat skills, and Aegon leading with his claim to the throne. They face various challenges like rival claimants and difficult terrains.
A meeting between them in fanfiction could be shown as a diplomatic encounter. Maybe Jon is sent back in time for some reason, and he has to negotiate with Aegon. He would use his wits and charm to make Aegon understand the future implications of his conquests. Aegon, being a shrewd leader, would listen intently and might even change some of his plans based on Jon's insights.
Their relationship could start off rocky. Jon, being a man of the North and having grown up as a bastard, might be skeptical of Aegon, who was raised with a sense of Targaryen royalty. However, as they face common enemies and challenges, they would gradually start to understand each other. For example, when they are both targeted by the Lannisters, they have to rely on each other's skills. Jon's combat expertise and Aegon's diplomatic knowledge could complement each other, leading to a grudging respect that over time turns into a deep friendship.
Well, perhaps in the fanfic, Aegon is initially seen as the rightful heir, but then Jon and Daenerys fall in love. Daenerys gets pregnant, and this throws the political landscape into chaos. Jon may have to fight for his place beside Daenerys and the unborn child, while Aegon might see the baby as a threat to his claim. There could be a lot of emotional turmoil, with Daenerys caught in the middle, trying to decide what's best for her child and the future of the Seven Kingdoms.
I'm not entirely sure if there is a specific fanfic with just that exact combination. But considering the popularity of these characters from 'Game of Thrones', it's very possible. Writers love to explore different relationships and scenarios among the characters. So, start your search on well - known fanfic platforms, and also look for fanfic communities on social media where fans might share their own creations or point you in the right direction.
Aegon could develop his combat skills under Arya's tutelage. He has been more of a political figure in the making, but Arya would teach him how to fight in a more practical and street - smart way. This would not only make him more confident but also change his perspective on power. Arya, on the other hand, would develop her diplomatic side. Aegon's knowledge of courtly manners and politics would rub off on her. She would learn to use words as weapons, in addition to her physical skills, which would be a great asset in her future endeavors.
The plot could involve a power struggle. Aegon wants to reclaim the Iron Throne for the Targaryens. Jon, on the other hand, has his own loyalties. They could start as rivals. But then, when a new threat emerges, like a powerful dark magic user who wants to rule Westeros through chaos. They are forced to put aside their differences. Jon's knowledge of the North and Aegon's Targaryen heritage could be combined to fight this new foe.
One possible plot could be that female Jon Snow, who has the same noble and somewhat conflicted nature as her male counterpart, meets Aegon. They initially clash due to their different upbringings and loyalties. For example, if Aegon has a claim to the throne and Jon Snow is still tied to the North, their paths cross in a political struggle. But as they get to know each other better, they start to understand and respect each other's viewpoints and might even fall in love, changing the political and personal dynamics of the story.
It could be an epic battle. Maybe they have a misunderstanding or are forced into a fight by external circumstances.
The relationships could develop in a very intense way. For example, if an Avenger comes back from a near - death experience, their comrades might be more protective of them. Or if a villain returns, it could make some of the Avengers who have grudges against that villain even more determined to take them down, strengthening their resolve and the bond within the team.
