Survival of the Fittest

Survival of the Fittest is the season finale of Season 7. It aired on May 18th, 2012.

Synopsis
Dean and Sam prepare for battle with Dick Roman. Dick's in the final phase of his master plan and the Winchesters must team up with Castiel, Bobby, Meg and Kevin, the prophet, to stop him. However, Dick is one of the smartest enemies they have ever faced, making it a mind game to see who can keep the upper hand.

Plot
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 deluding Sam and Dean with a vial of ordinary demon blood instead of his own, 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 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, 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 news images and video feeds 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 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.

Dean walks out to Cas sitting in the car listening to "Vincent " and taking in every word. Dean tries very hard to stow his exasperation as he attempts to inquire about Cas's motivation. In between expressing admiration for flowers and pondering the great mysteries of why humans test cosmetics on monkeys, Cas lets slip that he's been to Kevin's (the Prophet) 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. Leviathan, he points out, are the only creatures that can kill Angels (without an Angel Blade); 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 used on Crowley, and is angry. Just as she inquires what it's for, Crowley shows up with a vial of 'his' blood. Although, very displeased that the Winchesters are harboring both the betrayer Cas and Meg who wants him smote, Crowley decides to let Meg remain with the boys, as Cas has grown fond of her. Crowley realizes that Cas is functioning with precarious mental capabilities, including the inability or unwillingness to deal with any conflict. Cas is attuned to Meg, whom the boys don't fully trust. The boys want to keep Cas 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.

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 hairpins 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" in various areas of the building. Dick brings in Polly, he introduces Additive 3.0, a dairy creamer additive: his method for breeding out undesired characteristics, i.e. 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 she's 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 Rufus' Cabin after dropping off Louise the maid at an 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 'Dick copies' 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 if he knows anything that could help them and why Crowley insisted that he should come along. Castiel refuses and says he may destroy everything just like he did before. Dean angrily confronts him, that he should clean up the mess that he started, Cas responds by saying "you know, we should play Twister," displaying a game of Twister that he'd brought along. Then, Cas teleports away.

Meg berates Dean for making Cas leave, Meg then explains that Cas was the vessel of all the Leviathans and therefore should know 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 having them torch his flask; the only thing 'grounding' him as a ghost. The boys (and Castiel who is watching from the staircase) do as he asks and sadly watch as he passes/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 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 a 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 dairy 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 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 have vanished. 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 left all alone.

Dean is woken up by Cas in a dark forest, Cas 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 Cas isn't there. Dean is left all by himself, and the monsters are approaching...

Quotes

 * 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, Cas. 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: (waving the Bone Of Righteous Mortal Washed In the Three Bloods of Fallen around) Here's the thing about dealing with Crowley: he will always find a way to bone you.


 * (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 laughing, eventually explodes 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: 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.
 * Dean: We're in Purgatory? How do we get out?
 * Castiel: I'm afraid we're much more likely to be ripped to shreds.
