Well, healing is a big theme. The age - regression can be a way for Sam to heal from past traumas in many fanfictions. Also, relationship building. The OC and Sam form a special bond during this time. For example, in some stories, the OC helps Sam learn things anew, like how to trust again or how to have fun without the weight of his usual responsibilities. This creates a deep connection between them that forms the core of the story.
A prevalent theme is the exploration of innocence. Since age - regression involves going back to a younger state, there's often an exploration of Sam's lost innocence. The OC may be the guide in this journey, helping Sam navigate this new - found or rather regained sense of naivete. Additionally, self - acceptance is another theme. Sam has to accept this new state of himself, and the OC is there to support him through that process, which makes for an interesting and emotional read.
There's a lesser - known but really well - written one called 'Back to Innocence: Sam's Age Regression'. It has a detailed plot where the OC has to protect Sam during his regression period. The story not only focuses on the age - regression but also on the emotional journey of both Sam and the OC, exploring how they change and grow together.
One common theme is 'forbidden love'. Since Sam has his hunter duties, a relationship with an OC can be seen as something that goes against the rules of his world. Another theme is 'finding strength in each other'. The OC often brings out a different side of Sam, and they help each other grow and face challenges.
One common theme is the balance between family life and hunting. Sam has to figure out how to be a good husband while still going out and fighting the supernatural. Another theme is the impact on his relationships, like with Dean. His marriage can cause some tension or growth in their brotherly bond. Also, the idea of starting a new life with someone is often explored, like building a home and having a normal life despite his hunting past.
One common theme is self - discovery. When a character experiences age regression, they often have to rediscover themselves and their place in the world. Another theme is vulnerability. The regressed character is usually in a more vulnerable state, which can lead to interesting character dynamics.
One common theme is self - discovery. When Naruto regresses in age, he often has to re - learn things about himself and his abilities. For example, he might rediscover his ninja skills in a different way. Another theme is friendship. His relationships with his friends are re - examined, like how Sasuke might react to a younger Naruto.
The theme of family legacy is quite prevalent. Since they come from a family of hunters, many fanfictions explore how this family history affects their actions and decisions. Also, the theme of growing up in a tough environment is common. They face a lot of hardships at a young age, and fanfictions often depict how they cope with it and become stronger.
Since I don't actively engage with this type of fanfiction, I can't say for sure. But generally in fanfiction, themes might include the intense emotional connection between the characters, perhaps with a romantic or sexual undertone.
One common theme is the exploration of their deep emotional bond in a romantic context. Since they already have a strong brotherly bond in the original show, fanfictions often build on that to create a more intimate, romantic relationship.
One common theme is the idea of the oc being a powerful ally or a love interest for Dean. For example, many fanfictions have an oc with special powers that help Dean in his hunts.
The theme of self - discovery also appears frequently. As Naruto and Sasuke are in an age - regressed state, they have the opportunity to rediscover themselves without the burdens of their later - in - life experiences. They might learn new things about their personalities, abilities, and desires that were suppressed or forgotten as they grew older.
