I just got a new clip from Thursday's upcoming episode, "The Devil You Know."  It's got some really good Sammy angst and a crushing reveal for him.  So be warned if you're avoiding spoilers! I'm also including the clip I've been running earlier, the one with the demon Crowley.  Below is the description sent over from The CW and Warner Brothers.  It's a Ben Edlund episode, so it's likely to be intense! 

SAM AND DEAN FACE OFF AGAINST THE HORSEMEN - The demon Crowley (guest star Mark Sheppard) tells Sam (Jared Padalecki) and Dean (Jensen Ackles) he can help them find the remaining Horsemen rings so they can trap Lucifer.  The brothers are doubtful until Crowley leads them to Brady (guest star Eric Johnson), the demon Handler for Pestilence (guest star Matt Frewer) and Death.  However, Brady refuses to give up their locations and sets Pestilence after the Winchesters.  Robert Singer directed the episode written by Ben Edlund (#520).    





Here's the trailer too for those International folk that didn't get to see it
