Supernatural celebrates its 200th episode on Tuesday with what showrunner Jeremy Carver has called "a love letter to the fans." The episode finds Sam (Jared Padalecki) and Dean (Jensen Ackles) on a case at an all-girls school that's in the middle of producing a musical based on the Carver Edlund Supernatural books. But don't expect the musical to hew closely to canon.

What the Supernatural musical episode should look like

"The person who wrote what you're seeing on stage took some liberties," Ackles told us during a recent visit to the set. "Fans should expect to see "Some Sam and Dean stereotypes," added Padalecki.

In fact, the episode, titled "Fan Fiction," is part of a long-running Supernatural tradition of breaking the fourth wall and incorporating the show's fandom into the story line (think "The Monster at the End of the Book," "The Real Ghostbusters," and everything involving Becky Rosen). 

"The writers are very aware of what the fans think, and the fans are, I think, very aware that the writers are very aware of what they think," Padalecki explained. "So we've been able to kind of poke fun of ourselves in a way that we knew the fans would enjoy because they've kind of asked for it."
