TV Fanatic has done a great preview interview with Misha Collins. Check it out here. It's not too spoilery. As expected Misha would never give us.. well.. anything! I really can't wait to watch this episode. It has epic and game-changing written all over it. I am looking forward some kick-ass performance from the cast, I am looking forward to brilliant dialogues and I am looking forward to how the story progresses from this point onwards.
SAM, DEAN, CASTIEL AND MEG TEAM UP AGAINST CROWLEY AND HIS DEMONS — Castiel (Misha Collins) reappears in Sam (Jared Padalecki) and Dean’s (Jensen Ackles) life and tells them Crowley (guest star Mark Sheppard) has unleashed several demons into a small town. The demons are looking for Lucifer’s Crypt, which holds a valuable asset, but Castiel lies to Sam and Dean about what it is. While interrogating a demon, the three discover Crowley has been torturing Meg (guest star Rachel Miner), who knows the exact location of the crypt. Sam and Meg fight to hold Crowley off while Dean and Castiel go in search of the crypt. Thomas J. Wright directed the episode written by Robbie Thompson.
