In the episode called 'The Real Ghostbusters', Sam and Dean will meet people adoring them and dressing like them.
Jared Padalecki and Jensen Ackles are attending a "Supernatural" convention, on their show. Super fan Becky (guest star Emily Perkins) uses Chuck's (guest star Chuck Benedict) phone to trick Sam and Dean into attending a Supernatural fan convention, complete with fans dressed up as Sam and Dean.
One of the activities is a live action role playing game, but things quickly turn sour after a real ghost appears on the scene. Based on the casting call, there would be two young men named Demian and Barnes who are friends and have heroic aspirations despite their exterior appearance.
"The Real Ghostbusters" is an episode written by Eric Kripke and it will air on Thursday, November 12.
This would be one of those light episodes of "Supernatural" before the show goes on with a serious episode called "Abandon All Hope" on November 19. In that pivotal episode, Sam, Dean and Castiel track down the Colt and head off to find Lucifer to send him back to Hell. Jim Beaver said that the particular episode is "powerful and the fans will be left reeling."
