Survival of the Fittest

Survival of the Fittest is the 23rd episode and season finale of Season 7.

Synopsis
SAM AND DEAN STORM SUCROCORP TO TAKE DOWN DICK ROMAN — Dean and Sam prepare for battle with Dick Roman. Dick’s in the final phase of his 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’ve ever faced so it’s 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 offer's Crowley a deal-- the Demons get the entirity of Canada following the Leviathan siege 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, they 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).

The same Leviathan later brings Polly a dress to wear, complete with hair pins and accessories, one of which Kevin swipes and uses to pick the lock after Polly leaves with the creature.
