Story by Brett Matthews and Jenny Klein; teleplay by Brett Matthews.Directed by Robert Singer.Air Date: December 3, 2010.Sam and Dean make a tenuous alliance with the demon Meg in an attempt to get Sam's soul back from Crowley, but find that Crowley can't get back in the Cage to get it and it is now irreparably damaged from being in the Cage with Michael and Lucifer.
Curb-Stomp Battle: Even after Sam, Dean, and Meg seemingly have Crowley right where they want him, he manages to completely overpower them so fast, it's almost ridiculous. Bonus points for the look of bored amusement on his face after this happens.
Damaged Soul: Discussed. Cas thinks it might be better not to return Sam's soul to his body because of this.
Dynamic Entry: Dean kills Christian by sneaking up behind him and stabbing him with Ruby's knife before he even notices Dean is there.
Also, Meg and Castiel. This episode launches the trend of their sizzling chemistry getting a little less subtext.
Gambit Pileup: Let's see, there's Meg's plan to kill Crowley, Sam and Dean's plan to help Meg and then betray her, Samuel Campbell's plan to betray the Winchesters, and (as it turns out later on) Castiel trying to both help the Winchesters and keep Crowley alive.
Groin Attack: A seriouslySquick-y example: it is very strongly implied that when Christian is torturing Meg with a blade just off-screen, he's sticking it in her vagina and cutting her there with it. That's bad enough, right? Except the blade he's using is Castiel's sword, and cuts from angel swords are about as pleasant to demons as cuts from Ruby's knife. Even Dean and Sam look horrified by what happened to Meg.
Kiss of Distraction: Meg kisses Castiel to distract him and steal his angel blade from his trench coat. Backfires when Cas spins her around and kisses back, dumbfounding not only Meg but the Winchesters as well.
Meg approves of Dean's suggestion that he tear her to shreds, specifically because she likes how "kinky" it is. Must be the demon in her. Or possibly Alastair's influence. When it comes to actually being tortured, though, she isn't turned on in the least and is obviously in a lot of pain and discomfort (since she's got an angel sword through her...you know), but she does manage to criticize Christian's torture technique (even saying he's sticking the sword in all the wrong places) and flat-out laughs when she realizes he's about to be killed by Dean.
Villain Exit Stage Left: Subverted when Meg tries to flee her host and abandon Sam, Dean, and Castiel to the hellhounds...but can't leave her meatsuit. The "undignified" part of the trope stays in with Meg standing there foolishly with her mouth hanging open for a few awkward moments before she realizes that it just ain't working. Castiel then says that Crowley must have warded the building so that everything inside is locked inside their bodies to prevent this very situation. She finally does leave after she sees Crowley die, escaping before Dean could kill her. Dean admits that it was smart on her part.
