Additional Details


Fun Stuff

From "Supernatural: The Usual Suspects (#2.7)" (2006)
Det. Peter Sheridan: Talk directly to the camera. Start by stating your name for the record.
Dean Winchester: My name is Dean Winchester. I'm an Aquarius, I enjoy sunsets, long walks on the beach and frisky women. And I did not kill anyone. But I know who did. Or rather "what" did. Of course, it can't be for sure, because our investigation was interrupted. But our work in theory, is that were looking for some kind of Vengeful Spirit.
Det. Diana Ballard: Excuse me?
Dean Winchester: You know, Casper - the blood thirsty ghost.
