In fanfiction, if Sam was kidnapped, it could lead to a very intense story. Dean would surely go on a rampage to find him. Maybe Sam was kidnapped by a powerful demon who wants to use him for some dark ritual. It could also be a new, unknown enemy who has a vendetta against the Winchesters.
A lot of fanfictions also explore themes of sacrifice. Dean and Sam are often put in situations where they have to sacrifice something for each other or for the greater good. It shows their selfless nature. Also, the theme of redemption can be found in some, especially when they deal with characters who have made mistakes in the past.
Well, the theme of redemption is quite common. Whether it's Dean trying to make up for past mistakes or Sam finding his way back from a dark path. Love and friendship also play a role. Sometimes it's about their relationship with other hunters or people they meet. And of course, the struggle against fate. Many fanfics have them trying to break free from a pre - determined destiny.
I'm not entirely sure specifically about Sam from Supernatural blaming fanfiction. It could be that in some fan - created stories, the character of Sam was misrepresented in a way that the actor or the show's official stance didn't like. But without more context, it's hard to say for sure.
One common theme is Sam's struggle with his identity. Being a young hunter in a world full of the supernatural, he's constantly trying to figure out who he is and what his place is. For example, in many fanfics, he battles between his normal self and the part of him that has to be a hunter.
One common theme is the unrequited love. Often Becky has strong feelings for Sam, but Sam may be oblivious or hesitant. Another theme is Becky trying to fit into Sam's world of hunting and the supernatural. Also, there can be themes of redemption for Becky, as she has made some not - so - great choices in the show, and fanfiction can explore her journey to becoming a better person in relation to Sam.
One common theme is Sam's vulnerability. When he's sick, it shows a side of him that's not always on display. Another theme could be the brothers' relationship. Dean might be extra protective or worried. And sometimes, there's the theme of Sam fighting against whatever is making him sick, like a supernatural illness.
Often, the themes revolve around acceptance. Sam having to accept his new role as a 'Feedee' and how that impacts his self - esteem. There's also the theme of protection. Dean might be overly protective of Sam because of his 'Feedee' status. And in relation to the Supernatural elements, the fanfictions may deal with how Sam's condition is perceived by other hunters or even by supernatural creatures. Some stories might also focus on Sam's journey to overcome any negative aspects associated with being a 'Feedee' in the Supernatural world.
One common theme is the brotherly bond. When Sam is injured, it often showcases how Dean steps up to protect and care for him. Another theme is the struggle against the supernatural while being weakened. Sam may be injured, but he still has to face the threats out there. And there's also the theme of self - discovery. Sam might question his abilities and his place in the hunting world while he's recovering.
