One great fanfiction is 'AUs and What-Ifs'. It explores different alternate universes for Cas and Dean. It's really interesting as it shows their relationship in various scenarios that the show didn't touch on. Another one is 'The Road Less Traveled' which delves deep into their emotional bond and how they face challenges together outside of the main plot of the series.
One great piece of Supernatural Dean Cas fanfiction is 'AUs Are Made of This' which offers a really interesting alternate universe take on their relationship. It's full of heart - warming moments.
Another theme is sacrifice. Given the nature of the Supernatural world, they often put themselves in harm's way for each other. Fanfictions play on this selfless aspect of their relationship. 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.
The main reason is the relationship between Cas and Dean. Their dynamic in the show is complex and full of unspoken feelings. Fanfiction allows fans to explore that further. For example, they can write about what could have happened if certain events in the show turned out differently.
The theme of redemption can also be seen. Dean, with his often troubled past, might find a form of redemption through his relationship with Cas, who represents something pure and good in his life. And Cas, on the other hand, might find a new purpose in his existence through Dean, a way to truly belong in the human world.
One popular theme is the friendship - to - more relationship. Fans often explore how their deep bond could develop into something romantic. Another theme is their battles together against the supernatural. Writers love to describe their teamwork and how they rely on each other in dangerous situations.
The theme of love in different forms is very common. It could be platonic love, romantic love or a love that defies definition. Another is the theme of fighting against the odds. They face so many powerful enemies in the Supernatural world, and how they face these together is a big part of fanfics. Also, the idea of self - discovery is present. Both Cas and Dean are constantly learning about themselves, especially in relation to each other, in many fanfics.
I really like 'The Kiss in the Rain'. It's a bit of a classic in the dean and cas fanfiction world. The rain - soaked setting for their kiss adds a lot of drama and emotion. The story around it also does a good job of showing how their relationship has evolved over time.
Well, one key element is the build - up to the kiss. It often involves a lot of tension and unspoken feelings between Cas and Dean. Their complex relationship, with all its ups and downs, is another important part. It could be things like Cas's angelic nature clashing with Dean's more human way of dealing with emotions.
One common theme is the exploration of their deep friendship that could be something more. Many fics play around with the idea of unspoken feelings between them. Another theme is their shared experiences in fighting the supernatural. They face all kinds of monsters together, and this often forms the backdrop of the story. Also, the theme of sacrifice is quite common, as they are always willing to sacrifice for each other in these fics.
