What are some common themes in Supernatural Castiel and Dean Sick Fanfiction?

Romantic relationships between them are also a popular theme. Writers might explore how a relationship between an angel (Castiel) and a hunter (Dean) would work, dealing with the differences in their natures, their loyalty to their respective worlds, and how they overcome obstacles to be together.

One common theme is the exploration of their deep emotional connection. Since they have a strong bond in the show, fanfictions often delve into how that bond could turn into a romantic relationship. For example, stories might focus on how they deal with their feelings in a world where hunters usually don't have time for love.

Often, the theme of sacrifice is present. Maybe one of them has to make a big sacrifice for the other, and the kiss is a moment of intense emotion before or after that. It could also be about them breaking free from some kind of supernatural constraint that has been holding them back from being together, and the kiss is a symbol of their newfound freedom.

One common theme is loyalty. In many of these fanfictions, Dean and Castiel show unwavering loyalty to each other, whether it's facing the forces of evil in the Supernatural universe or dealing with personal issues. Another theme is sacrifice. They are often willing to sacrifice themselves for the other's well - being.

A lot of these fanfictions explore Dean's relationships while he's sick. His bond with Castiel could be deepened as Cas tries to heal him using his angelic powers. Or his relationship with his father might be revisited, thinking about how his dad would have reacted. It adds emotional depth to the story.

There are fanfictions with the theme of alternate universes. In these stories, Dean and Castiel experience different versions of their relationship. For example, in one universe they might be rulers of a supernatural kingdom, and in another they could be ordinary humans. These themes add a lot of variety and intrigue to the fanfictions.

One common theme is friendship. Their bond, whether it's a platonic friendship or something more, is often explored. Writers like to show how they support each other through tough times.

One common theme is the idea of unconditional support. Castiel is often depicted as being there for Dean no matter what, through his darkest moments. For instance, when Dean is haunted by his past actions or when he's feeling extremely guilty.

Some fanfictions focus on how their marriage affects the rest of the Supernatural universe. For example, how their relationship impacts Sam or other characters. There are also themes related to their different natures - Dean as a human and Castiel as an angel - and how they navigate their married life with these differences, such as Castiel trying to understand human emotions better for the sake of their marriage.

Another theme is the struggle between their different natures. Castiel being an angel and Dean being a human hunter. This creates a lot of internal and external conflict in the stories, like in 'The Clash of Worlds' fanfiction where they have to overcome their differences to be together.
