Perfect. Connor's Diner. Best burgers in St. Louis. Oh, I deserve something good in my life right now.
Conner's Diner is featured in episode 7.06 Slash Fiction.
Sam and Dean head to the next place where the leviathans should appear: St. Louis, Missouri. Dean looks forward to visiting Conner's Diner, which he says has the best burgers in the state. Unfortunately, Leviathan!Dean and Leviathan!Sam are already at the diner, where they force a teenage boy to record them on his phone as they kill everyone inside.
Agents Morris and Valente arrive on the scene and are shown the video, in which Leviathan!Dean reveals that they're going to be in Iowa next.
Dean and Sam are still driving when Bobby calls to tell them that decapitating the leviathans won't kill them, but will slow them down. He also gives them the news about the killings in Conner's Diner, so Sam thinks back over their past cases and figures out that their next stop should be Ankeny, Iowa.
When they arrive in Ankeny, they almost immediately spot Leviathan!Dean and Leviathan!Sam in a black Chevy Impala. They call Bobby, who tells them that they need to hang back, but they're determined to confront their doubles. Before they can, however, Sheriff Osborne and numerous officers surround and arrest them at gunpoint.
- The scene is very similar to a scene in the 1994 film Pulp Fiction, even the speech (minus the profanities of course).
- A famous author by the name of S.E. Hinton was in this scene. S.E. Hinton is famous for writing The Outsider that inspired a movie directed by Francis Ford Coppola and is a big Supernatural fan.
- Some people believe that Jensen's sister is one of the patrons of the diner, this has not been confirmed.
