First, you need to understand the character of Castiel well. Think about his relationships with Dean, Sam, and other characters. For example, his loyalty to Dean was a big part of his character. When writing his death, make it meaningful. Maybe it could be a sacrifice for the greater good, like protecting Dean from a powerful enemy. Then, focus on how the other characters react. Dean might be filled with guilt and anger, while Sam could be more focused on finding a way to bring him back.
One great Castiel - dead fanfiction is 'The Aftermath of an Angel's Fall'. It really delves into how the other characters in Supernatural deal with Castiel's death. It shows Dean's inner turmoil and Sam's struggle to come to terms with it.
One great aspect of Castiel and Dean in fanfiction is their dynamic. Their relationship, which is complex in the show, can be explored even further in fanfictions. Writers often delve into their unspoken bond, creating scenarios where they support each other in ways not shown in the original series. For example, some fanfictions might have them going on a road trip together just for the sake of exploring new places and having deep conversations about their pasts and futures.
Fanfiction about Castiel in Supernatural can be really interesting. Some 'hopeless' fanfictions might focus on his often tragic or difficult situations in the show. They could explore his loyalty to Dean and Sam even when things seem truly hopeless for him. Maybe it's about his struggle with his angelic nature and the chaos of the human world he's thrown into.
I remember reading a fanfic called 'Castiel's Wounds'. In this story, Castiel is severely injured during a battle with demons. The fic focuses on how Sam and Dean try to help him recover, and the relationship dynamics between the three are really well - written. It shows Castiel's vulnerability in a very believable way. There's also 'A World of Hurt' which explores Castiel's hurt in a post - apocalyptic setting, adding an extra layer of tension and drama.
Castiel's mind in Supernatural fanfiction is a fascinating topic. His experiences, such as being resurrected multiple times and his interactions with other supernatural beings, shape his mental state. In some fanfictions, his mind is explored through his dreams or hallucinations. These could be manifestations of his subconscious fears and desires. For instance, his fear of losing his friends might appear as a menacing figure in his dreams, representing the threats that constantly surround them in their supernatural adventures.
Perhaps in the fanfiction, Castiel betrays the group because of a misunderstanding. There could be a miscommunication regarding a prophecy or a powerful artifact. He might think that Sam or Dean are going to misuse it and decides to take it for himself to prevent that, but in reality, they had no such intention. This creates a rift between them and is seen as a betrayal.
I really liked 'Castiel's True Soulmate'. In this fanfic, the author creates a unique take on what it means for Castiel to have a soulmate. It has some really interesting plot twists that keep you hooked. There are also some great character interactions that stay true to the show's essence.
There is also 'Castiel's Choice'. This one is interesting as it focuses on Castiel having to make some tough decisions that directly impact his relationship with Dean. It's full of emotional moments and really makes you think about the depth of their connection within the Supernatural universe.
Yes, there are plenty of non - inappropriate Supernatural Castiel fanfictions. Many fans write stories that focus on his relationships in a positive, platonic or heroic way. For example, there are fanfictions about his loyalty to Dean and Sam, or his adventures in the Supernatural world that don't involve any inappropriate content.
Well, 'A Different Kind of Bond' is also a wonderful piece. It focuses on the emotional connection between the two characters. The story takes its time to build up their relationship, showing their growth and how they come to rely on each other more and more in the face of the supernatural threats.
