Wait, okay, this made me remember something I was thinking about.
Chuck stopped publishing the books at the point when Dean went to Hell, right? But Charlie asked in Pac-Man Fever if the events that occurred during the Apocalypse happened, brought up Castiel, etc. Chuck is shown finishing the book Swan Song. The Real Ghostbusters happened before Swan Song. Can you just imagine Demian and Barnes finding out that more Supernatural books were published? They go out and buy all of the copies and decide to read them. As their reading, Demian just goes ‘Holy shit’ and Barnes asks what’s wrong and he shows him their names in the book. He shows him the entire story and they read it over and over just to make sure that they aren’t crazy. And they realize that the guy they were talking to was really Dean Winchester. They fought ghosts with their heroes and they told the Dean Winchester that he didn’t know what the story, his life, was about because it’s amazing. They would just be completely blown away and it would be awesome.
