Lazarus Rising

S4 E1: In the fourth season premiere, it's been four months since Dean was dragged away by the hounds of Hell, the result of a deal he made with the Crossroads Demon in exchange for his brother's life. Now, Dean wakes up in a pine box. He's been freed from Hell, but he doesn't know how or why. He has a joyful reunion with Sam and fellow demon hunter Bobby (recurring guest star JIM BEAVER), but it isn't long before the three start to really wonder what exactly pulled Dean from Hell -- and what it will want in return.
