One common theme that can be made appropriate is his loyalty. This can be explored in a non - adult way, such as his loyalty to the Night's Watch or his family. For example, a fanfiction could focus on how his loyalty is tested when faced with difficult decisions regarding his Stark heritage and his vows to the Watch.
Another theme is his growth as a character. It could be about how he evolves from a young, naive boy to a strong leader. This can be told without any inappropriate content. For instance, stories could detail his experiences in battles and how they shape his leadership style and his view of the world.
His relationships, in a non - sexual sense, are also a common theme. His friendship with Samwell Tarly, for example. Fanfictions could center around how their friendship helps them both through difficult times at the Night's Watch, and how they support each other in their respective goals within the 'Game of Thrones' world.
One common theme could be the complex relationships among the characters in the harem. Each character might have a different connection to Jon Snow, be it love, loyalty, or something more complicated.
Love and romance are very common themes. Writers often explore how Jon and Val might fall in love, considering their different backgrounds and personalities. Another theme could be redemption. Maybe Jon has to make up for something he did wrong in the past, and Val helps him through it. There are also themes related to power and leadership, as both characters can be associated with some form of authority in different ways.
One common theme could be the exploration of family ties. Given that Lyanna Stark is Jon Snow's mother, some fanfictions might play around with how this relationship affects the story. Another theme could be love and passion, which is where the 'lemon' aspect might come in, showing the deep emotional and physical connection between the characters.
Not having read a 'Jon Snow fostered lemon fanfiction', we can only hypothesize. It might be that Jon Snow, while being fostered in some new place or by someone new, gets involved in a situation that is both challenging and has a touch of the 'lemon' nature. This could potentially mean that there are some spicy or tense moments in the story, perhaps related to a love interest or a power struggle that has a unique twist due to his fostered status. However, this is all speculation as the specific fanfiction doesn't seem to be a common one that is widely known.
One common theme is identity. Jon is often exploring his true identity, whether it's his Stark - Targaryen heritage or his role as a bastard turned leader. Another theme is loyalty. His loyalty to the Night's Watch, his family, and the North is frequently explored. And of course, there's the theme of love. His relationships with Ygritte and other potential love interests are a big part of many fanfictions.
A big theme is power and leadership. Both characters are leaders in their own right. Fanfictions may explore how they would combine their leadership styles. Also, the theme of family legacy is quite prevalent. Daenerys is a Targaryen with a complex family history, and Jon has his own secrets related to his family. Their family backgrounds play a role in how they interact and what they aim for in these fan - created stories. Additionally, there's the theme of trust - how they build it or lose it in different situations.
One common theme could be the power dynamic between them. Jon Snow is a natural leader, and Melisandre has her own brand of power with her magic. Their interactions in the face of challenges in Westeros might be a theme. For example, how they might team up to fight a common enemy.
Themes could include adventure and discovery. Maybe they embark on a journey together and during that, their relationship develops. There could also be a theme of redemption. If either character has made mistakes or has a troubled past, their relationship could be a means of finding redemption. Additionally, loyalty might be a theme, as they might have to be loyal to each other in the face of various challenges in the fanfiction world.
One common theme is family loyalty. Since they are both Starks, their loyalty to the family name and to each other as family members is often explored. For example, in many stories, they team up to protect the North and the Stark legacy.
Friendship is also a big theme. Many fanfictions focus on his relationships with Samwell Tarly and other comrades at the Wall. They show how these friendships help him survive and grow in that difficult environment. For example, they might go through challenges together like facing a wildling attack and their bond gets stronger as a result.
