Often, their relationship is shown as strained at first. Dean feels a great deal of guilt, which might make him over - compensate in trying to take care of Sam. Sam, on the other hand, might be a bit resentful or at least confused about what happened.
One popular 'Sam hurts Dean' fanfiction is 'The Broken Bond' where Sam makes a hasty decision during a hunt that leaves Dean seriously injured. It delves deep into their complex relationship post - the incident.
One popular 'Supernatural' fanfiction with this theme is 'The Unintentional Wound'. In it, Dean's actions during a hunt have unforeseen consequences that end up hurting Sam, both physically and emotionally. It delves deep into their complex relationship and how they deal with the aftermath.
One example could be a story where during a hunt, Dean accidentally fires his gun in the wrong direction and the bullet grazes Sam. The story then focuses on Dean's guilt and his attempts to make it up to Sam. Another might be in a more emotional context, like Dean saying something hurtful without meaning to during an argument, and the fanfic delves into how they repair their relationship.
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.
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.
