'''Season 6, Episode 20''':
!The Man Who Would Be King

As Castiel contemplates the details of the civil war in Heaven, and his history with Raphael, Bobby and the Winchesters begin to realize the angel is being less than truthful with them.

!Tropes
------
* AFormYouAreComfortableWith: There is a multitude of heavens whose form is established by the human souls within it, and the Angels live within whatever of these individual heavens they prefer. Castiel's favourite heaven is a beautiful garden created by an autistic man. Archangel Rafael's heaven is the office of a CorruptCorporateExecutive who repented.
* BadassBoast
* BetterTheDevilYouKnow: {{Discussed}}.
* ChewingTheScenery: Crowley of course.
* CoolAndUnusualPunishment / RightOnQueue: After Crowley took over Hell, he made an endless line consisting of millions of people the standard punishment. No agonizing torture like what Dean experienced during his time there, and instead of FireAndBrimstoneHell we get what looks like a long hallway that contains a line that requires people who reach the front to go all the way to the back of the line again.
* ConflictingLoyalties
* ColdBloodedTorture
* {{Confessional}}: Castiel's narration is essentially him confessing his sins to God.
* CurbStompBattle: Raphael easily defeats Cas when he refuses to start the Apocalypse.
* DangerouslyGenreSavvy: When Castiel tells him not to worry about the Winchesters, Crowley's almost outraged and spits out a list of super-powered heavyweights that said the same thing about them, all of whom are either dead or locked away at the Winchesters' hands. All by two human boys who "shouldn't have been any trouble for them."
-->'''Crowley:''' Am I the only game piece on the board who '''''[[SuddenlyShouting doesn't underestimate those denim-wrapped nightmares]]'''''?!
* ADayInTheLimelight
* DealWithTheDevil: Cas and Crowley have a deal to find Purgatory.
* DoNotTauntCthulhu
* EnemyMine
* EtTuBrute
* EvilCounterpart: We briefly meet the demon Ellsworth, who Castiel describes as being Bobby's counterpart. Not only does he sort of look like Bobby, complete with trucker cap, but we see him handling multiple calls with his minions in much the same way Bobby is seen handling calls with hunters (he even pretends to be an FBI agent to back up one's cover story, just like Bobby does all the time). And he calls one of his under-demons a "frickin' yeti", when Bobby and Dean refer to Sam as "sasquatch".
* GiveMeASign: Castiel ends the episode begging God to give him a sign that what he's doing is right or wrong. [[HaveYouSeenMyGod He gets no answer.]]
* HannibalLecture: Crowley to Castiel.
* HesBack: Lampshaded and subverted; Castiel turns up JustInTime to save the Winchesters, "For a brief moment I was me again" only to continue lying to them about Crowley.
* ICanExplain
* INeverSaidItWasPoison: A variation: Castiel accidentally [[CallBack calls back]] to a previous scene that [[spoiler: while he was '''present''', Bobby and the boys didn't see him because he was invisible]]:
-->'''Castiel:''' It ''is'' a little absurd, though.
-->'''Bobby:''' I know, I know.
-->'''Castiel:''' [[spoiler: {{Superman}} going to the dark side.]] I'm still just Castiel.
* IronicHell: It's a really long line that you have to wait in forever.
* LeaningOnTheFourthWall: Castiel starts the episode by looking straight into the camera and saying, "Let me tell you my story." Yes, yes, he was talking to God...
* MadScientistLaboratory
* ManipulativeBastard: Crowley.
* TheNarrator: Done in the form of Castiel praying to God.
* [[OhCrap Oh Hell]]: Ellsworth when Castiel barges in.
* OurAngelsAreDifferent: They don't have souls.
* {{Pride}}: Castiel's weakness.
* RevealingCoverUp: Castiel is too thorough in cleaning up after Ellsworth.
* RightBehindMe: Not PlayedForLaughs
* SoulPower
* SuddenlyShouting: A lot from Crowley.
* TakeThat: Castiel openly questions the fact that [[http://en.wikipedia.org/wiki/Kenneth_Lay Kenneth Lay]] was allowed to go to Heaven.
** France, which Crowley referenced when Cas [[CheeseEatingSurrenderMonkeys suggests they surrender.]]
* ThisIsThePartWhere: Dean says this is the part where they normally call on Castiel for help.
* TooKinkyToTorture: Souls who end up in Hell, according to Crowley.
* TowerOfBabel: Castiel remembers when the Tower Of Babel fell...all thirty-five feet of it. And it didn't fall because of divine retribution, it fell because dried dung can only be stacked so high.
* TrueCompanions: Castiel is visibly moved when Dean says he's like a brother to him.
* WellIntentionedExtremist: Castiel only wants to prevent Raphael from restarting the Apocalypse but [[JumpingOffTheSlipperySlope the way]] [[DealWithTheDevil he goes]] [[CivilWar about doing it]]...
* WholeEpisodeFlashback
* WithUsOrAgainstUs
* WoobieDestroyerOfWorlds: [[spoiler:Castiel is without doubt the most sympathetic BigBad yet.]]
