Trama

Sam and Dean make a plan to storm Dick's company building and kill him once and for all, with help from Castiel and Meg. Providing Bobby doesn't get to Dick first.

Dick Roman summons Crowley and makes a deal with the demon, asking him to give blood from a common demon to the Winchester brothers instead of his own. Meanwhile Dean and Sam get the bone of a nun and they just need Crowleys blood to prepare the weapon to vanquish Dick Roman. Dean and Sam also burn Bobby's flask so his ghost can rest in peace. EWen Crowley arrives, he tells his agreement with Dick to Dean and Sam and gives sample of his blood. Is Crowley betraying Dick Roman or the Winchester brothers?—Claudio Carvalho, Rio de Janeiro, Brazil

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/ threatening banter, Dick offers Crowley a deal - the Demons get the entirety of Canada following the Leviathan takeover of America in exchange for Crowley giving Sam and Dean a vial of ordinary demon blood to complete their weapon. Crowley accepts and pulls out a huge parchment with the terms, which he and Dick proceed to review and edit as needed.

Meanwhile, the Winchesters travel to a church crypt in search of a blessed bone. 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 who is still inhabiting the body of the Maid from the motel picks up supplies for his planned assault on Sucrocorp. His vengefulness is only incensed by the constant images and videos of Dick on the street.

After signing the contract with Crowley, Dick retrieves the real Dick Roman's hand (which they had cut off and saved on ice). He then gets several other Leviathans to morph into Dick's form in order to protect himself once Crowley (inevitably) betrays him.

Back at the Winchester hideout, the boys finalize their plan and summon Crowley for his blood, to no avail. While debating whether or not Crowley screwed them over, when Meg comes knocking, Castiel having found her hiding out and teleported her to the Winchester hideout.

Dean heads over to Cas and attempts to inquire as to his reason for looking for them. In between expressing admiration for flowers and pondering the great mysteries of why humans test cosmetics on Monkeys, Cas lets slip that he had been to Kevin's (the Prophet) house, only to find it ransacked and the Angels guarding him dead.

Before they can react, Meg finds the remnants of the failed demon summoning spell used on Crowley. Just as she inquires what it's for, Crowley shows up with a vial of 'his' blood. After a bit of displeasure at the Winchester's harboring both the betrayer, Cas and the treacherous Meg, Crowley decides to let them remain with the Winchesters to back them up until they kill Dick, subtely hinting that Cas can help out (even though he is a bit 'off').

He 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 bringing in a dazed looking girl named Polly (who is 'stoned out of her mind' on the Leviathan's food modifiying drug).

Meanwhile, Sam and Dean put together 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, he reassures the brothers that the ingredients are edible and the 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.

Back at Sucrocorp, Susan brings a box to Dick's office, and tells him that the delegates are on there way. Dick opens the box, it contains the real Dick Roman's arm with a watch around the wrist.

The same Leviathan later brings Polly a dress to wear, complete with hair pins and accessories. The delegates arrive and are greeted by Dick and Susan in front of Sucrocorp. The Leviathan returns to the room Kevin is locked in with a burger a bottle of water and fries, and takes Polly with him. Kevin picks the door with a hairpin he stole from Polly's outfit. Kevin sneaks around the halls and overhears the meeting between Dick and the delegates, he heads for the nearest exit but is caught by Susan.

Sam and Dean tap into cameras in Sucrocorp, and find three "Dick Romans", Dick brings in Polly, he introduces Additive 3.0: his method for breeding out undesired characteristics; Low Body Mass, Vertically Challenged, Hemophilia, IQ>150. Using Additive 3.0, he injects Polly using a syringe and she immediately froths from the mouth, collapses and dies.

Sam and Dean cycle through the cameras again, then Sam spots the maid from the hotel and realises shes possessed by Bobby, Sam tries to stop Bobby, but Bobby fights back, almost choking Sam to death, Bobby realises what he's doing and leaves the maid's body. After the scuffle, Sam and Dean head back to the Rufus' Cabin after dropping off the maid in the hospital.

Castiel and Meg are waiting for the boys back at the cabin, Meg asks why they didn't go through with the plan, Dean tells her to "shut up". Sam tells Meg and Cas that Dick made more 'Dicks' and 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 he knows anything that could help, and that Crowley said he should come along. Castiel refuses and says he may destroy everything just like he did before. Dean confronts him to clean up his mess that he started, Cas responds by saying "you know, we should play twister." Cas teleports away.

Meg berates Dean for making Cas leave, Meg then explains that Cas was the vessel of all the Leviathans and knows what each of them look like, meaning he could look past the meatsuits, and identify the real fake Dick Roman.

Later that evening Sam and Dean go 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 in. Bobby decides he needs to end it by torching his flask; the only thing keeping him as a ghost. The boys (and Castiel who is watching from the staircase) watch as he passes.

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 the plan, how Dick Roman knows they're coming.

The Impala is driving down the road, it drives right through the security and into the SUCROCORP sign. Meg gets out of the Impala with Borax and Machete. Sam, splits up from Dean and Cas while infiltrating the building. Meg decapitates the Leviathan security. Dean and Cas encounter one of the Dick Romans but Cas says it's not him.

Meg is thrown across the ground by two demons, one of them says "The King of Hell will see you now". Sam searches and finds Kevin, Sam unties him, Kevin tells Sam that they need to blow up the laboratory containing all the creamer.

Dick and another leviathan are in the labs packing the creamers, Dean and Cas decapitate the other leviathan and confront Dick. Dick thanks Castiel for letting his kind out of Purgatory and throws Cas across the room, Dean lunges and stabs Dick with the weapon. Dick is not affected. He pulls it out, breaks it in half, and taunts him, then Cas pulls Dick's head back and Dean pulls out the real weapon and stabs it sideways through the Dick's neck. Sam and Kevin burst in just as Dick is stabbed. An aura pulses from Dick Roman who grins maniacally then explodes into black goo.

Sam and Kevin look around the room to see that Dean, Cas and Dick are gone. Crowley and two other demons appear next to Kevin. Crowley says that Leviathans have become just another monster without their leader. He also says that he's taking the Prophet with him. Crowley and his men disappear, along with Kevin, and Sam is all alone.

Dean is woken up by Cas in a dark forest, Cas tells him it's 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. Dean notices two shadowy creatures with red eyes in the trees. He turns around to see that Cas isn't there. Dean is left all by himself...
