Another theme is the slow - burn romance. Writers often take their time building up the relationship between Cas and Dean. They might start as friends or comrades, and over time, the feelings of love gradually develop. It could involve a lot of longing looks, small acts of kindness that slowly turn into deeper affection.

For example, Cas might sacrifice his grace to save Dean, or Dean might risk his life to rescue Cas. It shows the depth of their bond.
Trust is also a big theme. When Cas makes a deal with Dean, they have to trust that the other will uphold their end of the bargain. In many fanfics, there are moments of doubt where one of them questions if the deal was a mistake. And of course, the theme of love, whether it's platonic or more, is always present.
