One common theme is redemption. Demon Dean often has a chance to redeem himself through his relationship with baby Sam. Another theme is protection. Dean, even as a demon, feels the need to protect Sam. For example, in many fanfictions, he'll fight off other demons who try to harm Sam.
One great 'demon dean and baby sam fanfiction' could be 'The Darkened Bond'. It delves into how Demon Dean might interact with a young Sam. Another is 'Demon's Redemption', which shows Dean's journey back to the light while protecting baby Sam. There's also 'Sam's Little Guardian' that focuses on the unique relationship between them in a more heart - warming way.
No. Fanfiction involving sexual content between characters is often not appropriate as it violates the boundaries of the original work and can be disrespectful to the source material and its fans. Moreover, it may also make many people uncomfortable.
For Dean, you could develop his character as a vampire by emphasizing his protective instincts, but in a more vampiric way. He might protect his territory or his 'blood sources' aggressively. His giggling could come from a place of enjoying the power he has. For Sam, his intelligence could be enhanced as a vampire. He could use his smarts to find new ways to survive. His giggling might be more of a nervous reaction to the new and often immoral things they have to do as vampires.
One great fanfiction could be where Dean and Sam have to face a unique Halloween - themed monster. Maybe a witch who uses Halloween traditions to cast powerful spells. They would have to use their wits and hunting skills to stop her before she causes chaos in a small town.
Well, it's possible that such a fanfiction exists. However, this would be a very strange crossover considering that 'Dean and Sam' are from 'Supernatural' and 'Harry' is from the 'Harry Potter' series. It might be a very niche or even a dark and edgy take on combining these two universes. But again, without a proper search on the relevant fanfiction platforms, it's difficult to say for sure.
A possible fanfiction plot could start with Dean being seriously hurt in a car accident on their way back from a hunt. Sam is distraught but quickly springs into action. He calls their hunter friends for help and takes Dean to the nearest safe house. There, he nurses Dean back to health. Sam is extra vigilant, setting up protective wards around the house and being overly cautious about any strangers approaching. He also spends time talking to Dean, helping him deal with the trauma of the accident both physically and mentally.
It could be that they love fanfiction that delves deep into their relationship. Stories that explore their brotherly bond more closely, perhaps with some emotional moments and how they support each other through tough times.
Another reason could be that fanfiction allows them to escape into a slightly different version of their world. It's like a form of relaxation for them. In fanfiction, they can experience things that haven't happened in their real lives yet, or see their relationships with other characters develop in new ways. Fanfiction gives them a chance to see themselves in different lights and situations, which can be both interesting and entertaining for them.
Sure. Sam and Dean often have moments that show their deep friendship. For example, when Dean was in danger, Sam would do anything to save him. They have supported each other through many tough times, like when they were facing powerful supernatural enemies. Their loyalty to each other is really remarkable.
