This episode summary is an official CW press release. It may contain errors.

Dean and Sam prepare for battle with Dick Roman (guest star James Patrick Stuart). Dick's in the final phase of his plan and the Winchesters must team up with Castiel (guest star Misha Collins), Bobby (guest star Jim Beaver), Meg (guest star Rachel Miner) and Kevin (guest star Osric Chau), the prophet, to stop him. However, Dick is one of the smartest enemies they've ever faced so it's a mind game to see who can keep the upper hand.


Following the customary montage of the season, the episode opens with Crowley having just been summoned to SucroCorp and imprisoned beneath a digital Devil's Trap. After a bit of semi-friendly yet threatening banter, Dick Roman offers Crowley a deal - demons get the entirety of Canada following the Leviathan takeover of America, in exchange for Crowley deluding Sam and Dean with a vial of ordinary demon blood instead of Crowley's own blood, to complete their Leviathan-killing weapon. Crowley accepts, and pulls out a huge contract with the terms, which he and Dick proceed to diligently review and edit as needed.

Meanwhile, the Winchesters travel to a church crypt in search of the bone of a righteous mortal. After considering several nuns, they finally agree upon Sister Mary Constant, a nun who devoted her whole life (83 years) to the order. Following a bad 'bone a nun' joke by Dean, the boys get to work extracting the bone.

Elsewhere, Bobby is still inhabiting the body of the maid from the motel—Louise—and he picks up supplies for his planned assault on SucroCorp. His vengeful urges are only incensed by the constant news, images, and video feeds of Dick on the street.

Back at Rufus's cabin, the boys finalize their plan and try to summon Crowley for his blood, to no avail. While debating whether or not Crowley screwed them over, Meg comes knocking. Castiel found her hiding place and teleported her to the Winchester hideout. Meg seems very irritated, and the boys are skeptical about her being there.

Dean walks out to Castiel, who is sitting in the car listening to "Vincent (Starry, Starry Night)" by Don McLean and taking in every word. Dean tries very hard to stow his exasperation as he attempts to inquire about Castiel's motivation for bringing Meg to the cabin. In between expressing admiration for flowers and pondering the great mysteries of why humans test cosmetics on monkeys, Castiel lets slip that he's been to Kevin's house, only to find it ransacked with the bodies of the angels who were meant to guard him. He's been around Creation looking for members of his former garrison, only to find that they're all gone. Leviathans, he points out, are the only creatures that can kill angels; that's why God locked them away in Purgatory in the first place.

Before they can react, Meg spies the remnants of the failed demon summoning spell for Crowley, and is angry. Just as she inquires what it's for, Crowley shows up with a vial of his blood. Crowley is very displeased that the Winchesters are harboring both the traitor Castiel, and Meg who wants him smote. However, Crowley decides to let Meg remain with the boys, as Castiel has grown fond of her.

Crowley realizes that Castiel is functioning with precarious mental capabilities, including the inability or unwillingness to deal with any conflict. Castiel is attuned to Meg, even though the boys don't fully trust her. The boys want to keep Castiel close, but know he will bail if they serve up Meg. Crowley has to play all of them if he wants to see his own plan come to fruition. Crowley then tactfully, indirectly warns them about Dick's knowledge of their plan and his countermeasures, before giving them the vial of blood and vanishing. Meg just stares on in fear.

Meanwhile, in SucroCorp, Kevin's futile attempt to open the door of his 'room' is foiled by a Leviathan in doctor's garb—Royce—bringing in a dazed-looking girl named Polly (who is "stoned out of her mind" on SucroCorp's dangerous food additive).

Back at the cabin, Sam and Dean put together the weapon by pouring the three kinds of blood over the bone, and they discuss if Crowley is double crossing them. Castiel appears with two sandwiches, and he reassures the brothers that the ingredients are edible and that he got the ingredients from a farm in Normandy. Sam asks Castiel why Crowley said they needed to bring him along, but Castiel cuts him off by saying that Crowley's wrong and he'd be waiting right here.

In SucroCorp, Susan brings a box to Dick's office, and tells him that the delegates are on their way. Dick opens the box, revealing that it contains an arm from the real Dick Roman, still with a watch around the wrist.

The Leviathan later brings Polly a dress to wear, complete with hairpins and accessories. The delegates arrive, and are greeted by Dick and Susan in front of SucroCorp. Dick returns to the room Kevin is locked in, to bring him a bottle of water, a hamburger, and French fries (despite Kevin saying he's vegetarian), and takes Polly with him. Kevin then picks the door with a hairpin he stole from Polly's outfit. Kevin sneaks around the halls, and spots Dick and the delegates gathered in a conference room. Kevin heads for the nearest exit, but is caught by Susan.

Sam and Dean then tap into cameras in SucroCorp, and find three "Dick Romans" in various areas of the building. In the conference room, Dick is seen bringing in Polly, and he introduces Additive 3.0, a dairy creamer. It's his method for breeding out undesired characteristics (i.e., low body mass, 'vertically challenged,' Hemophilia, and IQ>150). Dick injects Additive 3.0 into Polly, who immediately froths at the mouth, collapses, and dies.

When Sam and Dean cycle through the cameras again, Sam spots the maid from the hotel, and realises that she is possessed by Bobby, Sam tries to stop Bobby, but Bobby fights back, almost choking Sam to death. However, Bobby realises what he's doing, and leaves Louise's body. After the scuffle, Sam and Dean drop Louise off at a hospital.

When Sam and Dean arrive back at Rufus's cabin, Castiel and Meg are waiting for them. Meg asks why they didn't go through with the plan, but Dean merely tells her to "shut up." Sam tells Meg and Castiel that Dick made more 'Dick copies,' and they figure out that the Leviathans must have kept a part of the real Dick Roman so they could all touch and copy his appearance.

Castiel gets shaky and nervous, and Dean notices. He asks if he knows anything that could help them and why Crowley insisted that he should come along. Castiel refuses because he believes he will destroy everything just like he did before. Dean angrily confronts him, and demands that he should clean up the mess that he started. Castiel changes the subject by saying "You know, we should play Twister," displaying a box of Twister that he'd brought along. Then, Castiel teleports away. Meg berates Dean for making Castiel leave, and then explains that Castiel was the vessel of all the Leviathans, and therefore should know what each of them look like. Meaning, Castiel could look past the "meat suits" and identify the original Dick Roman copy.

Later that evening, Sam and Dean are going over what information they have on Dick, when Bobby appears. Bobby tells the brothers he's going vengeful, wanting to just grab "some poor bastard" and kill his way into SucroCorp. Bobby decides he needs to end it by having them torch his flask; the only thing 'grounding' him as a ghost on Earth. The boys (and Castiel, who is watching from the staircase) do as he asks, and sadly watch as his flask melts and Bobby leaves.

Castiel starts setting up his board games UNO and Mastermind when Dean walks in, Dean and Castiel are teleported to where the Impala is stored, they talk about forgiveness, Castiel agreeing to join them, the plan, how Dick Roman knows they're coming.

The next day, the infiltration of SucroCorp commences. The Impala is shown driving right through SucroCorp security and into the company's sign. Meg gets out of the Impala with Borax and a machete. Sam splits up from Dean and Castiel while infiltrating the building. Meg decapitates the Leviathan security guards. Dean and Cass encounter one of the Dick Romans, but Castiel says it's not the right one. Meg is thrown across the ground by two demons. One of them says "The King of Hell will see you now." Sam finds Kevin and unties him, before Kevin tells Sam that they need to blow up the laboratory containing all of the dairy creamer.

In the labs, Dick and another Leviathan are packing up the creamers. Dean and Castiel decapitate the other Leviathan, and confront Dick. Dick thanks Castiel for letting his kind out of Purgatory and throws him across the room. Dean lunges and stabs Dick with the weapon. Dick is not affected by it, because it wasn't coated in Crowley's blood. Dick pulls it out, breaks it in half, and taunts Dean. However, Castiel pulls Dick's head back and Dean pulls out the real weapon, and stabs it sideways through Dick's neck. Sam and Kevin burst in just in time to see. An aura pulses from Dick, who grins maniacally before exploding into black goo.

Sam and Kevin look around the room to see that Dean and Castiel have also vanished. Crowley and two other demons then appear next to Kevin. Crowley says that Leviathans have become 'just another monster' without their leader. He also says that he's taking Kevin with him. Crowley and his men disappear, along with the prophet, leaving Sam all alone.

Finally, Dean is woken up by Castiel in a dark forest, Castiel tells him they're in Purgatory, where the souls of monsters prey upon each other for eternity. Dean asks how they're supposed to get out of here, but Castiel replies that they're far more likely to be ripped to shreds first. Dean notices two shadowy creatures with red eyes in the trees. He turns around to see that Castiel isn't there. Dean is all by himself, and the monsters are approaching...

Featured Music[]


  • Crowley: It's not easy to kill me, but doable, especially for you lot. You kill angels. You can certainly wipe a demon off the board. And yet, here we are, negotiating like proper psychopaths.
  • Dick Roman: Full immunity for you and your constituency. I'm talking free-range grazing for all demonkind. I'm willing to cordon off, say, Canada. You and your crew can work your little deals, have your way with the locals.
  • Crowley: All of Canada?
  • Dick Roman: Have it.
  • Crowley: Fair. And down here?
  • Dick Roman: America's ours. Your sales team stays out – period. That's not up for negotiation. We need America. They're so fat.

[As Sam and Dean are about to break open a tomb to get the bone of a nun.]

  • Dean Winchester: Let's bone this nun.
  • [Sam gives him an exasperated look.]
  • Dean: ...Sorry.

  • Castiel: You know, Leviathan can kill angels. There's a reason why Father locked them in Purgatory. They're the Piranha that would eat the whole aquarium.

[After Castiel presents Sam and Dean with sandwiches]

  • Castiel: So. None of this should cause you any ill effect. I went to a little farm in Normandy for the wheat, and the lettuce, and tomato. And, I thoroughly examined, and comforted the pig before I slaughtered it for the ham. Here, you need your strength.
  • Castiel: Please accept this sandwich as a gesture of solidarity.

[After Dick makes copies of himself]

  • Sam Winchester: Dick made more Dicks!

  • Dean: We can't leave it. You let these friggin' things in. So you don't get to make a sandwich. You don't get a damned cat. Nobody cares that you're broken, Cass. Clean up your mess!

[Castiel walks up to Dean]

  • Castiel: You know... we should play Twister.

[Castiel vanishes; Sam and Dean exchange looks]

  • Meg: (dryly) Nice. You scared off the Empire's only hope.
  • Dean: Shut up, Meg.

  • Dean: So, what's it feel like?
  • Bobby Singer: What? Going vengeful? It's an itch you can't scratch out. Look... I'm done. Go get Dick. But don't do it 'cause you think it'll scratch the itch. Do it 'cause it's the job. And when it's your time... go.

  • Bobby Singer: (last words) Here's to seeing you guys on the other side. Just... not too soon alright?

  • Castiel: So, can I ask the plan?
  • Dean: Well according to Crowley, Dick knows we're coming. So we're gonna announce ourselves - big.

(Cut to the Impala crashing through SucroCorp's front gate and giant glass sign)

[Dean fails to kill Dick with the Bone Of Righteous Mortal Washed In the Three Bloods of Fallen]

  • Dick Roman: Did you really think you could trump me?
  • Dean: Honestly? No. (Pulls the real bone out of his jacket and stabs Dick through the neck while Castiel holds his head in place) Figured we'd have to catch you off guard!

(Dick pulsates energy waves and laughs, eventually exploding into black goo)

[After Dick is killed]

  • Crowley: You got what you wanted – Dick's dead, saved the world. So I want one little prophet. Sorry, moose. Wish I could help. You certainly got a lot on your plate right now. It looks like you are well and truly... on your own.

[Last scene, where Dean wakes up in a dark forest with Castiel]

  • Dean Winchester: Where are we?
  • Castiel: You don't know?
  • Dean: Last I remember, we ganked Dick.
  • Castiel: And where would he go in death?
  • Dean: (realizes) Wait, are you telling me...?
  • Castiel: Every soul here is a monster. This is where they come to prey upon each other for all eternity.
