They might be amused. Since fanfiction often contains creative and sometimes humorous takes on the original story, characters could find it funny to see how fans imagine different scenarios for them.
You can try websites like Archive of Our Own (AO3). It has a vast collection of Supernatural fanfictions. Just search for 'Supernatural' in the search bar, and you'll be presented with numerous options.
Not really. Given that he is a character who is interested in the affairs of the Supernatural world, fanfiction can be an extension of that world. It's just another way for him to engage with the story and the characters.
Well, I don't think so. NCIS is about solving crimes in the world of naval criminal investigations. The agents are usually busy with cases, interrogations, and forensic work.

Sam and Dean Winchester are always popular in Supernatural fanfiction, including those based on 13x17. Their brotherly bond and their roles as hunters are often central to many stories. Castiel is also a favorite. His angelic nature and his relationship with the Winchesters make him a great character to write about in relation to the events of 13x17.
Well, obviously Chuck himself is a very central and interesting character in these fanfictions. His all - knowing nature and his connection to the overarching story of Supernatural make him a key figure. Sam and Dean Winchester also play important roles as they are the main characters of the original series and often interact with Chuck in interesting ways in the fanfictions.
A popular character could be a half - werewolf, half - hunter. This character would be constantly torn between their two natures, and in a crossover, they could be a bridge between the werewolf community and the hunters in Supernatural.
On the other hand, it could cause some division. Some fans might love the idea and embrace it wholeheartedly, while others might think it's too far - fetched or not in line with the spirit of the original show. This could lead to debates and different factions within the fandom.
