Often, other characters might come to Dean's aid. Castiel could use his angelic powers to heal any internal injuries Dean might have sustained. There are fanfictions where Castiel hovers over Dean, his blue - eyed stare intense as he channels his grace to heal Dean's head injury from being knocked out.
The other hunters in the Supernatural world, like Bobby if he was still alive in the fanfic, would also be worried. They'd offer their expertise and resources to help Dean. Bobby might give Sam some advice on how to take care of Dean while he's unconscious and how to find the culprit.

It depends on who you ask in the Supernatural fandom. Some people are very against the idea of Sam and Dean making out in fanfiction. They believe it ruins the pure brotherly relationship that has been built up over the series. Others might be more open - minded and see it as just another form of creative writing within the fanfiction community. But generally, it's not something that is considered in line with the main themes and relationships of the show. So, while it might have its small group of supporters, it's not a widely accepted concept in the larger Supernatural fandom.
Another trope is the 'mysterious injury'. Dean gets hurt by some unknown or supernatural force. This then leads to an investigation to find out what caused the injury and how to stop it from happening again. Writers use this to create suspense and mystery in the story, keeping readers on their toes as they follow Dean's journey to figure things out while dealing with his pain.
Well, in these types of fanfictions, a common theme is often the struggle between their brotherly bond and this new romantic or sexual relationship. There's also the theme of secrecy, as they would have to keep this new relationship hidden from others in the Supernatural world. Additionally, some fanfictions might have a theme of redemption or acceptance. Maybe they initially feel guilty about their new relationship but then come to accept it. And sometimes, there's a theme of power dynamics, as they both have different personalities and abilities, and this new relationship could change how they interact in terms of power and control.
Dean would probably be extremely confused at first. He might stand there, staring at his car with a bewildered look on his face, muttering things like 'This can't be real'.
Dean could get some new ideas about how to deal with the challenges they face. The fanfiction might offer creative solutions to their problems. He might also start to notice little details about Castiel that he hadn't paid much attention to before, like the way he looks at him or the things he says, which could change their relationship dynamic in a positive way.
In fanfiction, Dean as a Prince of Hell can open up many interesting storylines. One possibility is that his character becomes darker and more conflicted. He might struggle with his newfound powers and the evil that comes with being a Prince of Hell. His relationships with Sam and Castiel would also be severely tested as they try to figure out how to deal with this new Dean.
