Perhaps the main conflict is that Adam's view of reality is very different from Sam and Dean's. Sam and Dean may be living in a sort of self - created world of hunting where they have their own rules and values. Adam coming in and giving a reality check means he is disrupting their status quo. For example, if Sam and Dean believe in always fighting monsters no matter what, Adam might present a situation where negotiation or understanding the monsters' motives could be a better approach. This difference in ideology would surely lead to conflict as Sam and Dean would have to defend their long - held beliefs against Adam's new perspective.
I haven't actually read this fanfic specifically, but generally, it might involve Adam presenting some hard truths or a wake - up call to Sam and Dean. Maybe he shows them a different perspective on their hunting lives, their relationships, or the consequences of their actions.
One common theme is loyalty. Dean and Sam are always loyal to each other in most of these fanfics, no matter what challenges they face. For example, in many stories, they will go to great lengths to save each other from danger.
Well, it's hard to say for sure without reading the fanfic. But Castiel is a very common choice as he has been so closely associated with Sam and Dean in the original series. There could also be some lesser - known angels that the author has created specifically for this fanfic. Maybe an angel that represents a different aspect of angelic society, like an angel in charge of angelic education or something, who takes a special interest in Sam and Dean.
One common theme could be the challenges they face. Maybe dealing with the reactions of their friends and family in the Supernatural universe. Another theme might be the change in their relationship dynamic, like becoming more protective of each other.
The theme of sacrifice is also prevalent. Since they are hunters, they are often put in situations where they have to sacrifice something for the other's well - being. This could be their own safety, a chance at a normal life, or even a relationship with someone else.
The fanfic 'angels adopt sam and dean' may have a plot where the angels see Sam and Dean as key players in a coming apocalypse or a major event in the supernatural realm. So, they take them under their wings. It could show the brothers learning new angelic magic or abilities. There may be a struggle between the angels' loyalty to heaven's commands and their growing attachment to Sam and Dean, which could lead to all kinds of interesting twists and turns in the story.
The uniqueness of Sam and Dean gay fanfic lies in the re - imagining of their relationship. It takes the deep bond they already have as brothers and twists it into a romantic and often more complex emotional connection.
It's interesting because it can explore different aspects of the Supernatural world from a new perspective. The 'dean girl sam' fanfic might introduce new monsters or magical elements that are related to the girl's backstory, which enriches the overall Supernatural universe in the story.
It could be Castiel. He's a very popular angel in the Supernatural universe and often has a connection with Sam and Dean, so he might be one of the angels to adopt them in the fanfic.
It could be demons. Demons are often the main antagonists in the Supernatural universe, and they might target Bella because she is related to the Winchesters. They could try to use her as a bargaining chip or a way to get to the brothers.
