History Recap / DoctorWhoS34E12DeathInHeaven

--->'''Voice:''' ''[over the intercom]'' "Mr. President, you're needed in the briefing room."\\
'''The Doctor:''' "Remember when all you wanted to do was rule the world?" ''[to the intercom]'' "On my way." ''[back to Missy]'' "Piece of cake."

-->'''The Doctor:''' "I am not a good man! And I'm not a bad man. I am not a hero. I'm definitely not a president, and no, I'm not an officer. You know what I am? [[PunctuatedForEmphasis I. Am...]] ''an idiot!''"

-->'''Doctor:''' "Of course. Earth's [[DarkestHour darkest hour]] and mine… where else would you be?"

-->'''Danny:''' "This is not the order of a general... nor the whim of a lunatic--"\\
'''Missy:''' ''"Excuse me?!"''

-->'''The Doctor:''' "You win."

-->'''Seb:''' "Permission to {{SQUEE}}--" \\

-->'''The Doctor:''' "All of this... all of it just to give me an army?"\\
'''Missy:''' "Well, I don't need one, do I? Armies are for people who think they're right! And nobody thinks they're righter than you. Give a good man firepower and he'll never run out of people to kill!"\\
'''The Doctor:''' "I don't want an army!"\\
'''Missy:''' "Well that's the trouble! Yes, you do! You've always wanted one! All those people suffering in the Dalek camps? Now you can save them! All those bad guys winning all the wars? Go and get the good guys back!"\\
'''The Doctor:''' "Nobody can have that power."\\
'''Missy:''' "You will. Because you don't have a choice. There's only one way you can stop these clouds from opening up and killing all your little pets down here! Conquer the universe, Mister President. Show a bad girl how it's done."\\
'''The Doctor:''' "Why are you doing this?!"\\
'''Missy:''' "I need you to know we're not so different. [[IJustWantToHaveFriends I need my friend back.]] Every battle, every war, every invasion, from now on, you decide the outcome. What's the matter, Mr President? Don't you trust yourself?"

--->'''SantaClaus:''' "Hello? Doctor? You know it can't end like that! Hmm? We need to get this sorted and quickly! She's not all right, you know! And neither are you!"

-->'''Clara:''' "I would never, ever, give up the Doctor. Because he is my best friend, too. He is the closest person to me in this whole world. He is the man I will always forgive, always trust, the one man I would never, ever lie to."\\

-->'''Osgood:''' "Three?"\\
'''Missy:''' "I'm accelerating for dramatic effect."

-->'''The Doctor:''' "I am not a good man! And I'm not a bad man. I'm not a hero. I'm definitely not a president. And no, I'm not an officer. You know what I am? I... am... an idiot! With a box and a screwdriver, passing through, helping out, learning. I don't need an army, I never have. Because I've got them. Always them. Because love, it's not an emotion. Love is a promise. [[ThePowerOfLove And he will never hurt her.]]"

-->'''Clara:''' "Ask anyone who knows me, I'm a terrific liar."\\
'''Danny:''' '''"Correct."''' [zaps Clara unconscious]\\
'''Skarosa:''' '''"No order was given."'''\\
'''Danny:''' '''"Correct."'''\\
'''Skarosa:''' '''"You are not under cyber control."'''\\
'''Danny:''' [blasts three Cybermen] '''"Correct."'''

-->'''The Doctor:''' "I had a friend once. We ran together, when I was little. And I thought we were the same. But when we grew up, we weren't."

-> ''"I had a friend once. We ran together when I was little and I thought we were the same. When we grew up, we weren't. And now she's trying to tear the world apart and I can't run fast enough to hold it together."''

JustForFun/{{The one with}}[[CameBackStrong the Cyber-Brigadier.]]

* AllPartOfTheShow: The crowd in front of St. Paul's Cathedral thinks the Cybermen are street performers. Missy even passes the hat for them. Subverted, however, when it turns out the crowd are all undercover UNIT agents moving into position.
* AmbiguousCloneEnding: Given that Osgood's Zygon duplicate was alive and well the last time we saw either of them, this raises the question of which version Missy killed.[[note]]Given how the Zygons die in ''The Zygon Invasion'' and ''The Zygon Inversion'' is different to the way this Osgood dies, it's implied that this is ''the'' original human Osgood.[[/note]]
* AndYourLittleDogToo: Missy kills Osgood and tries to kill Kate Stewart, solely because the Doctor likes them.

* ArmchairMilitary: Again, Danny accuses the Doctor of being this, this time when Clara insists on activating Danny's emotional inhibitor in his stead. He makes quite a point of rubbing it in before he dies, to the point of calling him a "bloodsoaked general".
* AwesomeButImpractical: As befits an AirborneAircraftCarrier -- the ''Valiant'' has been discarded as too conspicuous[[labelnote:*]]Wasn't it destroyed by the Daleks the [[Recap/DoctorWhoS30E12TheStolenEarth last time]] we saw it?[[/labelnote]]. Unfortunately it doesn't take the Cybermen long to find Boat One either, presumably because Missy is transmitting her position.
* AxeCrazy: Missy displays [[ComicBook/TheJoker Joker]] levels of murderous glee, fully admitting she's completely nuts and enjoys doing it. She sticks Osgood's murder on the same level as popping balloons and justifies the act of killing her despite her strategic value because she's bananas.
* BackForTheDead: Osgood hasn't been seen since "[[Recap/DoctorWho50thASTheDayOfTheDoctor The Day of the Doctor]]", and now she's killed by the Master. Or at least one version of her is.

** She follows it up with a boast that would scare almost any creature in the universe.
--->'''Kate:''' Welcome to the ''only'' planet in the universe where we get to say this: ''[indicates the Doctor]'' He's on the payroll.

--->'''Voice:''' ''[over the intercom]'' Mr. President, you're needed in the briefing room.\\
'''The Doctor:''' Remember when all you wanted to do was rule the world? ''[to the intercom]'' On my way. ''[to Missy]'' Piece of cake.
** Missy calling herself the "Queen of Evil".
** '''Danny:''' This is a promise. The promise of a soldier. You will sleep safe tonight.

-->'''The Doctor:''' I am not a good man! And I'm not a bad man. I am not a hero. I'm definitely not a president, and no, I'm not an officer. You know what I am? [[PunctuatedForEmphasis I. Am...]] ''an idiot!''
* BewareTheNiceOnes: The Brigadier could be dangerous ''before''. Now he has Cyber Weapons. Would ''you'' like to get on his wrong side?
* BeYourself: After much of the series explored the themes of accepting others even as you get to know their edgier sides and imperfections over time and the Doctor's repeated questioning of his own morality, he reaches the conclusion that while he's not a perfect or necessarily heroic person, that doesn't make him a bad person or the villain, "officer" or "destroyer" he's been accused of being -- he's simply "an idiot with a screwdriver and a box, passing through, helping out, learning". After seeing him spend so much time agonizing over past mistakes displaying serious self-hatred, it's quite touching.

-->'''Doctor:''' Of course. Earth’s [[DarkestHour darkest hour]]… where else would you be?
* BigDamnKiss: The Doctor very gently, very sweetly kisses the Mistress. Consensually this time!

* BittersweetEnding: The Doctor finally seems to accept himself and, to an extent, get over his self-hatred ("... and I am not a bad man."), but he winds up alone again after the deaths of Osgood and Missy, having had to accept that Missy cannot be reformed and was probably never "like him" in the first place. Danny gets the chance to come back thanks to the Mistress's interdimensional teleport bracelet, but sacrifices it so the innocent boy he shot can live. The Doctor, thinking Danny has come back, lies to Clara that he's decided to stop travelling, go home and help rebuild Gallifrey, so that she won't feel torn about staying on Earth with Danny. Clara lets the Doctor go on thinking that she has a future with Danny so he won't feel torn about leaving her behind. Both of them go back to their old lives, alone.[[note]]Until Santa Claus comes along, apparently to put things right.[[/note]]
* BodyHorror:
** Danny's cyberized corpse looks every bit as dead as it should be from what little is seen of it, with various bits of technology drilled into his face.
** The moldering cadaver of the Brigadier has been hardwired into a Cyber-suit. Because he doesn't say a word as a Cyberman, we don't know if he even possesses the faculties to speak anymore.

** The Mistress uses the Second Doctor's "Oh my giddy aunt" when Osgood discovers the Mistress' handcuffs in her pocket. She also uses Clara's "Seriously?" when it looks like the Doctor will shoot her in Clara's stead.

* TheBusCameBack:
** The Brigadier returns, one last time, as a Cyberman to save his daughter from a fatal fall.
** Not ''quite'' back, but close. After being put on the bus a half-decade earlier, Jenny, [[Recap/DoctorWhoS30E6TheDoctorsDaughter the Doctor's daughter]], not only gets a shout-out, but the way Clara describes her strongly suggests the Doctor is aware that she is alive.
* ButtMonkey: ''Belgium.'' First [[Recap/DoctorWho2007CiNSTimeCrash Five and Ten]] mock the poor country for being the exact size of a temporal explosion, and now Missy for not even being French...

* CameBackWrong: The dead get to come back to life, but as mindless Cybermen. There are a couple exceptions, like Danny Pink and the Brigadier, that get to retain their humanity. Danny, despite the emotional inhibitor, still loves Clara and will not harm her ("Love isn't an emotion, it's a promise!"). The Brigadier just managed through his love for his daughter and his country.
* CardCarryingVillain: Missy calls herself "the Queen of Evil".
* CasualDangerDialogue: While staring down dozens of Cybermen and ''the Master'', Kate Lethbridge-Stewart takes time to banter with the Doctor about his new regeneration, and boasts to the Cybermen about [[MundaneMadeAwesome her expertise in bridge and gardening]].
* ChekhovsGag: Hah! The Brigadier only ever wanted the Doctor to salute him! We weren't expecting him to actually come back...
* {{Cincinnatus}}: Again, the Doctor unwittingly winds up as a President, this time of Earth. As usual, he has no interest in power and just wants to get rid of it as soon as possible. This quality is also what allows him to resist the Mistress' temptation.

--->'''Kate:''' Welcome to the ''only'' planet in the universe where we get to say this: ''[indicates the Doctor]'' He's on the payroll.
** Clara calls herself [[Recap/DoctorWhoS34E9Flatline "The Doctor", again]]. Only this time, she's genuinely trying to pass herself off as him.

** Clara's mentioning of the Doctor having four marriages (all deceased) refers to (in the Doctor's chronological order) Susan's grandmother, [[Recap/DoctorWho50thASTheDayOfTheDoctor Queen Elizabeth I]], [[Recap/DoctorWho2010CSAChristmasCarol Marilyn Monroe]] and [[Recap/DoctorWhoS32E13TheWeddingOfRiverSong River Song]].

** The Mistress sings "Hey Mickey" (or rather "Hey Missy"), showing that the Mistress [[Recap/DoctorWhoS29E12TheSoundOfDrums still loves pop songs just like her]] [[Creator/JohnSimm previous incarnation]].
** When Osgood finds The Mistress' cuffs in her coat pocket, The Mistress mockingly exclaims "[[Characters/DoctorWhoSecondDoctor Oh my giddy aunt]]".
** The coordinates the Mistress gives the Doctor when she tells him Gallifrey has returned to its old location are the same coordinates given for Gallifrey in "[[Recap/DoctorWhoS13E3PyramidsOfMars Pyramids of Mars]]" and "[[Recap/DoctorWhoS18E3FullCircle Full Circle]]".

** Missy's plan to create an army through converting the dead into Cybermen recalls the [[Recap/BigFinishDoctorWho Macqueen Master's]] (the first incarnation of the post-Eye of Harmony regeneration cycle, which Missy is a part of) penchant for building armies via AssimilationPlot.

* ContinuousDecompression: Colonel Ahmed is sucked out of Boat One when a Cyberman shatters a window and evicts him by force, almost certainly sending him to his doom. Then Kate, when the Mistress blows an entire panel from the side of the aircraft.

* DemotedToDragon: The Cybermen here are unquestioningly (with the odd exception where the conversion didn't take) loyal to Missy. It's possible that they aren't "real" Cybermen at all, but simply undead slaves in identical-looking shells created by Missy using stolen Cyber-conversion technology.
* DontCallMeSir: The Doctor still doesn't like being saluted, even when he's President. Danny makes a point of calling the Doctor "sir", but it's not a term of respect but a CallBack to when he called the Doctor an officer.
* DontLookAtMe: Cyber-Danny turns his back on Clara when she walks towards him.
* DrillSergeantNasty: When Cyber-Danny is given the controls to the Cybermen, he berates them in much the same way he did his first class of students.
* DyingMomentOfAwesome: Danny leads the entire Cyber-Army into their final act: "The Promise of a Soldier: You Will Sleep Safe Tonight."

* EvilIsPetty: Apart from his/her natural tendency to kill anyone who annoys her (or just because it amuses her), the Mistress also gets the Doctor's hopes up that Gallifrey has returned, just so they'll be crushed again.

** Gallifrey's location? Right where it always was. Apparently the Doctor never bothered to check. [[SubvertedTrope Then]] it turns out that the Mistress lied, to nobody's surprise. Only for it then to be revealed in Hell Bent and Heaven Sent, that she ''wasn't'' technically lying -- the location in space is true but Doctor didn't go ''far enough'' forward in time.

* {{Foil}}: Beyond the usual Master/Doctor contrast, we have Clara as a counterpart for the Master, especially with the revelation that she chose her, perhaps even because she saw her younger self in her. Both are good friends of the Doctor who to an extent share his eccentric genius characteristics, but are capable of being somewhat savvier in social situations. Both have been part of his life for a long time, have a certain deceptive side to them and are people that he feels a strong affinity towards. The difference is that while Clara might screw up, she'll regret it and try her best to be a good person even if she doesn't always succeed, while the Master fully embraces her evil. In the temptation scene, the Doctor essentially has to choose which of them he wants to be like.

* ForegoneConclusion:
** By the time the episode aired, it was already known that Clara would return in the Christmas special, so the farewell scene here was only ever expected to be temporary.
** Given precedent during the character's long history, no-one seriously expected Missy to be KilledOffForReal.
* {{Foreshadowing}}: Kate gets rattled when the Doctor comments that Missy's "convert the dead" plan must have been going on for a long time.
* ForgotAboutHisPowers: During the Eccleston and Tennant eras, the Doctor stated he could sense the existence of other Time Lords if they were still alive somewhere in the universe. This was such a crucial plot point that the Master himself in his first appearance in the modern series had to [[ItMakesSenseInContext mask his presence via a psychic satellite network]]. Now it seems that not only can the Doctor not sense the presence of the Mistress, but he cannot tell whether Gallifrey, an entire planet full of Time Lords, has returned.

%% * GettingCrapPastThe Radar: Due to overwhelming and persistent misuse, GCPTR is on-page examples only until 01 June 2021. If you are reading this in the future, please check the trope page to make sure your example fits the current definition.
* GoodIsNotSoft: Unexpectedly invoked by Clara, a character who is not known for using deadly force (and likely hasn't killed anyone directly up to this point if one doesn't count shooting a couple of technically-already-dead Cybermen in Series 7's "[[Recap/DoctorWhoS33E12NightmareInSilver Nightmare in Silver]]"), being perfectly willing to kill Missy in cold blood if the Doctor doesn't do it.
* GotVolunteered: Kate explains to the Doctor that in the event of worldwide invasion, international law dictates that a president be appointed to command all of Earth's forces. There was only one candidate.
* TheGuardsMustBeCrazy: The two soldiers supposedly guarding the Mistress are about as much use as a chocolate teapot. They don't even react when Missy and Osgood stop whispering and start talking aloud about the former's statement that she's going to kill the latter. Although much criticized, this may be a ContinuityNod as the Master was known for using hypnosis to make people do his bidding. Which in this case might have been to stand by and do nothing while she escaped.
* HardLight: Seb is a program interface, and is promptly disintegrated when he starts to irritate the Mistress.
* HeroicSacrifice: Cyber-Danny and his army of Cybermen sacrifice themselves to remove the clouds covering the Earth. He then later relinquishes his one chance at resurrection to bring back the boy he killed as a soldier.
* HeroicSelfDeprecation: The Doctor rejects the Mistress' claim that they're similar by proclaiming that he is "an idiot with a box and a screwdriver".

** Then there's Brigadier Lethbridge-Stewart, also cyber-converted, who retains his humanity because [[TheBrigadier of course he does]].
--->'''The Doctor:''' Of course. The Earth's darkest hour, and mine. Where else would you be?
* HoistByHisOwnPetard: Missy brought the Doctor and Clara together basically to screw with him. Clara then insists that he ShootTheDog. In a more abstract way, her continued support throughout the series and the fact that she's an example of someone who shares some of the Doctor's character flaws, but still registers as a likeable person to him might've contributed to the exact way he rejects the Mistress's temptation in the end.

** The Mistress seemed to be seriously considering sparing Osgood, based on Osgood's argument for keeping her around; she even compliments Osgood on her quick thinking. Then she disintegrates her anyway.
** In the end, when her plans have been foiled, the Mistress gives the Doctor Gallifrey's coordinates and suggests he and she could go back together, even if it meant that she'd be imprisoned. Then she's killed, and it turns out the coordinates were a lie, apparently.
** For a brief moment it appears as if Danny might return from the Nethersphere, until he chooses another option by sending back the boy he killed.

* IChooseToStay: Discussed, but subverted; when Clara begins to mention incoming bad news (that, in reality, Danny is still dead and used his chance to return for the boy he accidentally killed), the Doctor immediately assumes the usual "I want to settle down and get married and dangerous time travelling doesn't fit into it" routine, and, to alleviate potential feelings of guilt, claims that he's found Gallifrey and intends to live there/stop the adventuring himself. In truth, Danny's still dead and Gallifrey is still lost, and it is likely that both Clara and the Doctor would have continued as usual even if they weren't.
* TheILoveYouStigma: Averted between Clara and Danny, however, her promise to never say "I love you" again to anyone else establishes this stigma between herself and the Doctor that continues through Series 9.

-->'''Danny:''' This is not the order of a general, nor the whim of a lunatic--\\
'''Missy:''' ''Excuse me?!''

* IronicEcho: To The Master's last words in "[[Recap/DoctorWhoS29E13LastOfTheTimeLords Last of the Time Lords]]":
-->'''The Doctor:''' You win.

** The Doctor is interrogating the Mistress on her EvilPlan when UNIT knocks him out with a tranquillizer.
** The Mistess taunts the Doctor with this trope once she's escaped on Boat One. She then explains it in the graveyard (JustifiedTrope as the Doctor has to know ThePlan) but like all villains is too busy EvilGloating to notice her plan unravelling.
* KickTheDog: According to Steven Moffat, Osgood is killed off to remind the audience that [=Missy/TheMaster=], for all her [[DracoInLeatherPants amusing quirkiness]], is irredeemably evil.

-->'''Seb:''' Permission to {{SQUEE}}-- \\

* KillTheCutie: The Mistress murders Osgood, taunting her with the knowledge that she's going to kill her before doing so. Then she crushes her glasses underfoot.

-->'''The Doctor:''' All of this... all of it just to give me an army?\\
'''Missy:''' Well, I don't need one, do I? Armies are for people who think they're right! And nobody thinks they're righter than you. Give a good man firepower and he'll never run out of people to kill!\\
'''The Doctor:''' I don't want an army!\\
'''Missy:''' Well that's the trouble! Yes you do! You've always wanted one! All those people suffering in the Dalek camps? Now you can save them! All those bad guys winning all the wars? Go and get the good guys back!\\
'''The Doctor:''' Nobody can have that power.\\
'''Missy:''' You will. Because you don't have a choice. There's only one way you can stop these clouds from opening up and killing all your little pets down here! Conquer the universe, Mister President. Show a bad girl how it's done.\\
'''The Doctor:''' Why are you doing this?!\\
'''Missy:''' I need you to know we're not so different. [[IJustWantToHaveFriends I need my friend back.]] Every battle, every war, every invasion, from now on, you decide the outcome. What's the matter, Mr President? Don't you trust yourself?
* LackOfEmpathy: What the Doctor names as the main significant difference between himself and the Mistress (and by implication, beings like Daleks and Cybermen). He gets things horribly wrong sometimes, but at least he cares about the damage that is done, which is why he tries not to.

** TheStinger:
--->'''SantaClaus:''' Hello? Doctor? You know it can't end like that! Hmm? We need to get this sorted and quickly! She's not all right, you know! And neither are you!
** The CreditsGag is aimed squarely at fans who complained about Clara becoming too much the focus of Series 8. (Some even starting to call the series ''Clara Who''.)
** It was also created to tweak fans with the hint of how a female Doctor might play out, given the revelation involving the Mistress in the previous episode. It also, in the long term, reflected Clara's ongoing character arc of becoming the Doctor's DistaffCounterpart.

-->'''Clara:''' I would never, ever, give up the Doctor. Because he is my best friend, too. He is the closest person to me in this whole world. He is the man I will always forgive, always trust, the one man I would never, ever lie to.\\

-->'''Osgood:''' Three?\\
'''Missy:''' I'm accelerating for dramatic effect.

* MoodWhiplash: [[Recap/DoctorWhoS28E13Doomsday Yet]] [[Recap/DoctorWhoS29E13LastOfTheTimeLords again]], a ''Doctor Who'' finale about to end on a very low note runs headfirst into a "WTF?" moment. This time, ''Santa Claus''.
* MoralityChain: A rare example where two characters are this for ''each other'' in equal parts, exemplified by the parallel scenes where Clara and the Doctor show themselves willing to spare each other from having to off someone in a potentially devastating way, explicitly referred to as "saving [the other's] soul." It's also played with in the sense that for once, the resident Companion doesn't stop the Doctor from destroying someone, but [[KillTheOnesYouLove from sparing them despite his lingering attachment to them]], as the Mistress is just so dangerous and hard to contain that [[ShootTheDog shooting the dog]] is really the more moral option.

* NiceJobBreakingItHero: By saving Gallifrey, the Doctor released the Master from the Time Lock. This means that they are now around to cause trouble.
* NightOfTheLivingMooks: The Mistress' Cybermen go from mutilating and converting the living to spread their ideology, to utilizing the dead to create an unstoppable army. Less visceral, but clever and still very macabre. Said word for word by Danny.
* NoodleIncident; Despite the reveal that Missy is an incarnation of the Master, the circumstances of her regeneration from her last incarnation to her current one -- and what caused her gender change -- go unmentioned.... [[Recap/DoctorWhoS36E12TheDoctorFalls for now]].

-->'''The Doctor:''' I am not a good man! And I'm not a bad man. I'm not a hero. I'm definitely not a president. And no, I'm not an officer. You know what I am? I... am... an idiot! With a box and a screwdriver, passing through, helping out, learning. I don't need an army, I never have. Because I've got them. Always them. Because love, it's not an emotion. Love is a promise. [[ThePowerOfLove And he will never hurt her.]]

** Still an ongoing theme with Clara and the Doctor; she impersonates him well enough to have a bunch of Cybermen confused for a while even though her bio-scans read as human. It sort of helps when they're making use of each other's survival skills and stopping each other from doing things that might ruin them, but backfires when they both lie to each other so they can enjoy their supposed happy endings guilt-free... when no happy ending exists in the first place.

** The Doctor and UNIT when they do the numbers on how big an army of the dead is, when the Mistress has had all of human history to assemble one from.

* OurZombiesAreDifferent: The Cybermen created by Missy are corpses given full cyber-upgrades, deleted emotions and barely anything of a personality; pretty similar to regular zombies, in that their bodies have decayed, and the emotions and personality are gone. Unlike regular zombies, they can talk, have a hive mind, are a bit more endurable, can fly, and don't need to be bitten to spread -- it happens via {{Nanomachines}} after their victim dies. Bonus points for the Mistress fitting various characteristics of a [[OurLichesAreDifferent Lich]], one of the typical creators of zombie armies.

** As usual, love trumps Cyberconversion, allowing Danny to retain his own mind even after having his emotional inhibitor turned on. The Doctor learns it's why Cyber-Danny wouldn't kill Clara. "Love isn't an emotion. It's a promise."
** Love allows Brigadier Lethbridge-Stewart to save his daughter and defend his country.
** The Doctor and Clara's love for each other, be it platonic or implied romantic, is so strong they mutually sacrifice the opportunity to keep travelling with one another in the mistaken belief that this will allow the other to find their own happy endings (the Doctor believing Clara has been reunited with Danny; Clara believing the Doctor is returning to Gallifrey).
* PreemptiveDeclaration: Missy tells Osgood she will kill her in a minute. She does too, even counting down the time ForTheEvulz. She [[Recap/DoctorWhoS29E13LastOfTheTimeLords still]] can't resist a countdown.

* RageBreakingPoint: The Doctor ''pulverizes'' his TARDIS console controls until sparks fly out when he sees that Gallifrey is absent from its space-time coordinates. (This scene is all the more disturbing because the TARDIS is ''alive'', meaning he is shown beating up ''his longest-serving companion'' in anger. The only time he's done that before was [[Recap/BigFinishDoctorWhoNEDASDarkEyesE1TheGreatWar after losing three companions in one day]].)
* TheReasonYouSuckSpeech: Danny gives a ''doozy'' of one to the Doctor, noting how his RousingSpeech about embracing emotion and the importance of one's humanity are utterly worthless when Danny completing his Cyberman conversion will give them a "tactical advantage" because it will allow Danny full access to the Cybermen's HiveMind. When the Doctor can't bear to be the one to turn on the emotional inhibitor, Danny bitterly remarks that [[ArmchairMilitary officers never get their hands dirty]]; this is ''after'' calling him "blood-soaked".

* RogueDrone: Both Danny and Brigadier Lethbridge-Stewart are Cybermen who are not under Missy's control.

** The Doctor gives one of his own as he explains to Missy the nature of love and friendship, though it triggers a TheReasonYouSuckSpeech from Danny (see above).
** For someone who insists he isn't an officer, Danny gives a great one to the Cybermen army of the dead, urging them to make a HeroicSacrifice for the sake of the living. Since he is talking to the entire Cyber-Army through the control bracelet, ''he is the SergeantRock for the whole world.''

* ScheherezadeGambit: Clara tries to convince the Cybermen that she's the Doctor and therefore worth keeping alive. Cyber-Danny intervenes before we get to find out if it works.
* SchmuckBait: Missy lures Osgood close to whisper a secret to her. Subverted in that Missy then utterly fails to attack her.
* ScifiWritersHaveNoSenseOfScale: So apparently Missy has, all on ''this single incarnation,'' been travelling throughout human history and uploading every human who has ever died into her cyber army, and despite this contradicting other ''Who'' canon, this is apparently the entire reason humans have a concept of an afterlife. Just to put this in perspective, at out current population levels, two humans die ''every single second''. Assuming she were to start with the death of the very first ''Homo Sapiens'' and progress linearly from there, Missy would've aged into the gnome-like form she previously accelerated the Doctor to in "[[Recap/DoctorWhoS29E13LastOfTheTimeLords Last of the Time Lords]]" centuries before humans even entered the bronze age.
* ShipSinking: The death of Danny on its own does not qualify under the trope criteria. What does qualify is when Clara, not realizing the Cyberman she's talking to is actually Danny, talks about how the Doctor (''not'' Danny) is the one man she's closest to in the entire world, and the one man she'd never lie to and would always trust (considering that a source of conflict throughout the season between Clara and Danny is her penchant for lying to him about the Doctor).
* ShootTheDog: Discussed and carried out; Clara insists that Missy is too dangerous to be spared, which prompts the Doctor to agree to do it to spare her the experience. In the end, it's the Brigadier, a seasoned professional with no personal attachment to her and who never had any qualms about solving problems with explosives who ultimately disintegrates her for the sake of his old friend; the Doctor is visibly grateful. He even salutes!

** The Doctor calls the ''Valiant'' [[Series/CaptainScarletAndTheMysterons Cloudbase]]. Osgood claims that's from ''Series/{{Thunderbirds}}''. Colonel Ahmed corrects her.
** In response to the above, the Doctor mentions once dancing with Creator/SylviaAnderson, who voiced Lady Penelope in that series, and was the glamorous wife of Creator/GerryAnderson (who created both shows).

** Fans were already pointing out the Mistress' dress sense as similar to Literature/MaryPoppins, but in this episode she makes it even more explicit by descending into the graveyard while hanging from an umbrella. This may also have been a nod to longstanding fan theories that Mary Poppins was, in fact, a Time Lady (not helped by one of the ExpandedUniverse novels implying that the Doctor possesses Mary's carpet bag).
** When the Mistress hands over the bracelet that controls the Cybermen to the Doctor, she wishes him a happy birthday, then turns on a husky voice and sings "[[Creator/MarilynMonroe Happy birthday, Mr. Presideeent]]". Especially funny since Clara mentions the Doctor's four marriages earlier in the episode, one of which was to Monroe.
* SparingThemTheDirtyWork: Near the end of the episode, the Doctor is faced with the fact that killing Missy is the only way to stop her causing more havoc in future. [[spoiler:Brigadier Lethbridge-Stewart]] rescues him from the dilemma by vaporizing her himself, since he's a soldier and for him the question of killing one person to save others is already settled.
* StarCrossedLovers: Subverted; Clara realizes that she and Danny aren't the lovers who commit TogetherInDeath that Amy and Rory were (remember that Amy wrote the book Clara was reading in "[[Recap/DoctorWhoS33E6TheBellsOfSaintJohn The Bells of Saint John]]"), apologizing to him that while she wasn't really good at it, she did love him.

* StealthSequel: To the Seventh Doctor Big Finish audio drama "[[Recap/BigFinishDoctorWho049Master Master]]", where the Doctor tried to get the Master to be his friend again, here Missy tries to get the Doctor to be ''her'' friend again. Each tried by trying to get to the other to see things from their point of view.
* {{Squee}}: Seb straight-up invokes the trope by name when the Doctor manages to skydive into his falling TARDIS. The Mistress, unimpressed, and rather pissed at her unfaithful lackey, vaporizes him for it.

** When Osgood mentions the Mistress is in the former Prime Minister files, she adds "She wasn't even the worst."

* {{Teleportation}}: Missy's bracelet allows her to travel to the Nethersphere and return to a different location on Earth (which would explain her OffscreenTeleportation in the previous episode).

** The Doctor invites Osgood to travel with him, in the Mistress' hearing.

** Clara calls herself the Doctor, proclaiming herself to be an incredible liar, and Cyber-Danny agrees. He would know.

* ThisCannotBe: Missy is surprised that Cyber-Danny did not obey her orders.
* ThrowAwayCountry: The Mistress orders the Cybermen to blow up the airplane -- and Belgium.
-->'''The Mistress:''' Yeah, kill some Belgians. They're not even French!

** The Cybermen can now fly, and the Mistress can convert the dead into more Cybermen instead of just the living.

* TooDumbToLive: The most basic security procedures would've kept Osgood from being killed. Osgood does her research on Missy's device ''ten feet'' from where they're holding said psychotic Time Lady prisoner, despite knowing exactly who she is and [[Recap/DoctorWhoS9E3TheSeaDevils how human prisons means nothing to her]]. There's not even a wall separating them, and [[DistressBall Osgood doesn't run as soon as Missy tells her she's going to die]]. While they’re probably hypnotized by Missy (who the Third Doctor established can control basically any human mind), the guards don’t even move.
* TooSpicyForYogSothoth: Danny is able to break his conditioning, as is the Brigadier. Danny is even able to arrange to return the young boy he killed from whatever afterlife he ends up in.

* TheTriple: The end of Clara's rapid-fire BlatantLies - a - thon to the cybermen.
-->'''Clara:''' Ask anyone who knows me, I'm a terrific liar.\\
'''Cyberman:''' '''Correct.''' [zaps Clara unconscious]\\
'''Other Cyberman:''' '''No order was given.'''\\
'''Cyberman:''' '''Correct.'''\\
'''Other Cyberman:''' '''You are not under cyber control.'''\\
'''Cyberman:''' [blasts three cybermen] '''Correct.'''
* UndyingLoyalty: At various points of the episode, both Clara and the Doctor declare this towards each other. Unusually and perhaps more realistically, the emphasis is less on that they'd never do anything to disappoint each other (which they have done in the past, and even Clara's one declaration of "never" is contradicted by the end of the episode) but on how the occasional fallibility on either side isn't enough to make their importance for each other go away.

** The Doctor doesn't think that the Mistress being female is in any way unusual, and he doesn't comment on it. (His previous regeneration once mentioned in passing that he was acquainted with at least one other Time Lord/Lady who swapped genders, so he was well aware it could happen.) He simply switches pronouns to "she" and that's that. He's briefly worried that UNIT might not believe him, but Osgood doesn't see it as anything unexpected either.

* VillainsDyingGrace: Subverted. After refusing to tell the Doctor Gallifrey's location, the Mistress recites its coordinates after her EvilPlan is foiled. She lied.
* VillainsNeverLie: Averted; the Mistress lies to the Doctor about Gallifrey's location.
* WakingUpAtTheMorgue: Danny Pink's body was stored at the morgue of a funeral home when he was converted.

* WeCanRuleTogether: Attempted by the Mistress, as usual, who gives the Doctor control of the Cybermen to try and get him to admit that they're similar.
* WeUsedToBeFriends: The Doctor and the Mistress as usual, but Missy wants to change that.
-->'''The Doctor:''' I had a friend once. We ran together, when I was little. And I thought we were the same. But when we grew up, we weren't.

** Clara: "I'm the Doctor."
** Missy to Osgood: "[[PrepareToDie I'm going to kill you.]]"
** When the Doctor is about to execute Missy.
--->'''The Mistress:''' [[PreMortemOneLiner Say something nice.]]\\
'''The Doctor:''' [[TheBadGuyWins ... You win.]]

* WhamEpisode: Danny, Osgood, Seb, and the Mistress (presumably, the Mistress has cheated death many times) all die. At first it looks like Clara will no longer be a companion, but Santa Claus has something to say about that.
* WhatHappenedToTheMouse: The fate of the young boy Danny returns from the afterlife is never revealed, in this episode nor any of the Clara-Twelve episodes that follow. Nor is it explained how the boy could exist assuming his actual body by this time had to have either been destroyed or buried.
* WithGreatPowerComesGreatInsanity: The reasoning behind the Mistress's attempt to tempt the Doctor into becoming just like her by giving him an army of Cybermen. [[{{Cincinnatus}} The Doctor is rather horrified, and resists.]]

* ZombieApocalypse: Functionally this is what the Mistress' plan creates, an army of undead with which to conquer the world but it comes with the twist that the zombies are Cybermen souped up with Time Lord technology.

JustForFun/{{The one w|ith}}here [[TheBrigadier the Brig]] [[BackFromTheDead came back...]] [[CameBackStrong as the Cyber-Brigadier.]] [[ButNowIMustGo Then left to parts unknown...]] probably to go find a new mustache and a uniform that fits the new robot body.

Meanwhile, back at St. Paul's, a flock of tourists descend to gawp and gaggle at the shiny metal men. Missy is amused, and quickly flicks through various video feeds to show more and more clusters of them, in every major city in the world. One of the tourists steps forward to take the Doctor and Missy's picture, a familiar-looking woman in a spiffy-looking bowtie and familiar Converse... [[Recap/DoctorWho50thASTheDayOfTheDoctor Osgood]]. And just like that, the "tourists" whip out their guns, and UNIT springs into action. Out comes Kate Stewart, decidedly unimpressed at this whole "Cyberman apocalypse" thing -- [[Recap/DoctorWhoS6E3TheInvasion they tried it forty-six years prior, didn't work then]], and UNIT's specifically built anti-Cyberman weaponry from the remnants of their dead in case they tried to stage a repeat. In response, the Cybermen... fly off with shiny new rocket boots. Several more spew from the Cathedral itself, ninety-one in total -- one for every city in the British Isles.

Kate has both Missy and the Doctor tranqued — Missy for the obvious reason, the Doctor because she doesn't want to risk him getting bored and wandering off before the world's been saved -- and taken aboard Boat One (an airborne UNIT base [[Recap/DoctorWhoS29E12TheSoundOfDrums a bit less Helicarriery]]). As it turns out, after the Harold Saxon business, the governments of the world decided to automatically make the Doctor acting President of Earth (whether he wants to be or not) should another global UNIT-level disaster occur. The Doctor, in between complaining about being saluted at and declaring that he's never going to salute back (although he admits to Kate that he would have done it for her father if he'd realised how much it would have meant to him), quickly figures out that Missy has been using modified [[Recap/DoctorWhoS14E3TheDeadlyAssassin Matrix technology]] to store human minds for as long as humans have believed in an afterlife. Meanwhile, Osgood, who was just being offered a companion position by the Doctor for being generally clever and awesome today, finds herself guarding Missy.

Clara, meanwhile, ''isn't'' actually the Doctor. She can't keep that bluff up for very long, even with the detailed knowledge of the Doctor's life she's picked up over time, but she doesn't need to -- Danny, now a Cyberman but with his original memories and emotions intact, takes her away from 3W and into a graveyard, where the corpses are already being cyberconverted by the Cyber-pollen. Their programming hasn't kicked in yet, and he begs her to turn on his emotional inhibitor so he's not in pain anymore. The Doctor is interrupted in his emotional conversation with the Mistress when Clara calls him, asking him to help her. But the Doctor refuses -- not only because he knows that fully converting Danny will make the Cyberman kill her, but also because Danny's link to the hivemind can help save the Earth. Missy merrily reveals that [[Recap/DoctorWhoS33E6TheBellsOfSaintJohn she was the woman in the shop who put Clara and the Eleventh Doctor together]] (because she ''loves'' to see the uncontrollable Doctor being controlled by such a control freak), then ruptures the plane, gets Kate flung out into the sky, and orders her Cybermen to kill some Belgians for the sheer hell of it.

Down on Earth, Danny reveals that he can only access the hivemind once he's converted; the Doctor knows that he has no choice but to turn on Danny's emotional inhibitor forever. He can't bring himself to do it, and Clara takes the sonic and performs the act herself.

The Mistress joins them in the graveyard, in grand style, and reveals her plan... the rain will kill all humans on Earth, then convert them into more Cybermen. And the Cyberman troops are meant for the Doctor. He can use it to win every war, to liberate all the slaves in Dalek camps across the universe, to settle every dispute in his favour. She wants to see him lead an army, wants to make him admit that he's just like her, that he needs to feel in charge. Because she just ''wants her old friend back''. The Doctor, suddenly understanding, finds in her words the answer to his question: [[ArcWords is he a good man?]] He gets down on his knees for her and kissing her, very gently, in thanks, he explains to her that he isn't. And he's not a bad man either. Or a general. Or a president. Or a hero. He's just an idiot with a box and a screwdriver, helping, learning.

He throws Missy's control bracelet to Danny (who's still holding firm against cyberconversion with ThePowerOfLove, which is not an emotion but a promise) and Danny is able to lead the army of Cybermen into the clouds, making a HeroicSacrifice to destroy all the dark water once and for all.

In the midst of this, the Mistress gives the Doctor a present: the location of Gallifrey. It's in the one place the Doctor hasn't thought to look -- back at its old coordinates where it had always been before the Time War.

Clara has surreptitiously taken Missy's death ray, and doesn't plan on letting her get away [[JokerImmunity to come back with a new atrocity next week]] -- instead, she's going to murder the Time Lady in cold blood. The Doctor won't let her. Not because he can't bear to see his old friend die, but because he can't bear to see his companion become a killer. He promises Clara that if that's what it will take to dissuade her, he'll kill Missy himself.

Missy mocks him: such a sacrifice, to save Clara's soul. But who will save the Doctor's soul? She gets her answer in the form of an unexpected death ray from offscreen, which (apparently) disintegrates her on the spot.

There's one Cyberman left -- one Cyber-Leader who has not only just zapped her, the Doctor and Clara discover, it's also taken the time to catch Kate Stewart when she fell from the doomed aircraft and bring her safely to earth. And Kate is muttering about her dad... yep. [[Recap/DoctorWhoS5E5TheWebOfFear Once upon a time]], the Doctor met a man, a man of unquestionable courage, a man of grit, and a man of honour. This man helped saved the Earth on many, many, occasions, so would anyone be ''that'' surprised that not even death itself would prevent the late Sir Alistair Gordon Lethbridge-Stewart from coming to the Doctor's aid one final time? Like Danny, and demonstrating the will to break free of Missy's control, because he's still very much [[HeroicWillpower the iron-willed]] [[TheBrigadier Brigadier]] he was in life, he Doctor realises his old friend is standing before him, [[Recap/DoctorWhoS32E13TheWeddingOfRiverSong and he now has the chance to say good-bye.]] The Doctor gives his old friend a first and last salute, and the cyberconverted Brigadier nods his head in acknowledgement, then rockets into the sky and out of sight.

Clara tries to go back to her normal life, only to hear Danny's voice in her apartment one night. He still has that control bracelet and it's good for one trip back from the afterlife. But instead of coming back himself he sends through the child that he killed in the war, asking Clara to take care of the boy, and says his final goodbye.

The Doctor seeks out Gallifrey's coordinates and to no one's shock, Missy trolled him; it's still in the pocket dimension [[Recap/DoctorWho50thASTheDayOfTheDoctor he left it in at the end of the Time War]]. In anger, he flies into a violent rage against his TARDIS console and soon after breaks down crying.

He and Clara meet up at a café for their final goodbye. Seeing her depowered control bracelet, which she's wearing as a memento, he assumes that she and Danny are happily back together now. And that there will be no place for a TARDIS and a Doctor in her life. Before she can correct him, he tells her that he's found Gallifrey, and he'll be living there from now on, so there's little point in her and Danny being bothered by him anymore. They share a final hug, on Clara's insistence, neither willing to admit their lie.

[[Recap/DoctorWhoS34E11DarkWater By the end of the last episode]], Danny Pink was dead and a dozen Cybermen were clanking down the steps of St. Paul's. The Master -- the Mistress now, or "Missy" for short -- had revealed herself with a flourish, and the Doctor was left to stare as a full-scale alien invasion descended upon the Earth. And Clara Oswald was left trapped in a room, with a Cyberman rapidly approaching...

Meanwhile, back at St. Paul's, a flock of tourists descend to gawp and gaggle at the shiny metal men. The Mistress is amused, and quickly flicks through various video feeds to show more and more clusters of them, in every major city in the world. One of the tourists steps forward to take the Doctor and Mistress's picture, a familiar-looking woman in a spiffy-looking bowtie and familiar Converse...

The one where [[TheBrigadier the Brig]] [[BackFromTheDead came back...]] [[CameBackStrong as the Cyber-Brigadier.]] [[ButNowIMustGo Then left to parts unknown...]] probably to go find a new mustache and a uniform that fits the new robot body.

** In response to the above, the Doctor mentions once dancing with Creator/SylviaAnderson, who voiced Lady Penelope in that series, and was the glamorous wife of Creator/GerryAnderson (who created both shows)

** In response to the above, the Doctor mentions once dancing with Sylvia Anderson, who was the glamorous wife of ''Thunderbirds'' creator Gerry Anderson and the voice of Lady Penelope in that series.

** Osgood continues to be a walking Doctor costume homage of Theta Sigma-inspired attire. After wearing a big, floppy scarf like the Fourth Doctor, her latest outfit has a leather jacket, [[NiceShoes Converse sneakers]] and a burgundy bow tie -- favoured by the [[Recap/DoctorWho50thASTheDayOfTheDoctor War, Tenth and Eleventh Doctors]] respectively.

* SpareThemTheDirtyWork: Near the end of the episode, the Doctor is faced with the fact that killing Missy is the only way to stop her causing more havoc in future. [[spoiler:Brigadier Lethbridge-Stewart]] rescues him from the dilemma by vaporizing her himself, since he's a soldier and for him the question of killing one person to save others is already settled.

** The Brigadier returns, one last time, as a Cyberman to save his daughter from a fatal fall. It's an ingenious way of getting around ActorExistenceFailure.

* FascinatingEyebrow: The Doctor gives Santa the Raised Brow of ArbitrarySkepticism.

* AmbiguousCloneEnding: Given that Osgood's Zygon duplicate was alive and well the last time we saw either of them, this raises the question of which version Missy killed.[[note]]Given how the Zygon's die in ''The Zygon Invasion'' and ''The Zygon Inversion'' is different to the way this Osgood dies, it's implied that this is ''the'' original human Osgood.[[/note]]

* StuffedIntoTheFridge: Osgood was killed by the Master purely because a) The Doctor liked her and b) Moffat wanted to show that The Master was still evil even though she was a woman. He admitted saying "Osgood was the one we flung on the fire to make the Master burn brighter." Luckily, it was later revealed that either the original Osgood or her Zygon double was still alive, and she refused on principle to explain which one she was. The same story ends with ''another'' Osgood duplicate being created, as well.

* NoMoreNoldingBackSpeech: The Doctor finally answers the Arc Question: Is he a good man? He does so in good measure, just before beating Missy.

'''Missy:''' I need you to know we're {{not so different}}. [[IJustWantToHaveFriends I need my friend back.]] Every battle, every war, every invasion, from now on, you decide the outcome. What's the matter, Mr President? Don't you trust yourself?

** Kate throws down a Telosian Cyberman's head in front of the newly arrived ones from "the last time they tried".

* DecapitationPresentation: When the Cybermen boast to Kate that Earth lacks the technology to beat them, she drops the head of a Telosian Cyberman just to show them what happened to the last batch of Cybermen who thought messing with humanity was a good idea.
* DemotedToDragon: The Cybermen here are unquestioningly (with the odd exception where the conversion didn't take) loyal to Missy. It's possible that they aren't "real" Cybermen at all, but simply Cyber-drones created by Missy using stolen Cyber-conversion technology.

* NiceJobBreakingItHero: By saving Gallifrey, the Doctor released the Master from the Time Lock. This means that the Mistress is around to cause trouble.

* OurZombiesAreDifferent: The Cybermen are corpses given full cyber-upgrades, deleted emotions and barely anything of a personality; pretty similar to regular zombies, in that their bodies have decayed, and the emotions and personality are gone. Unlike regular zombies, they have a hive mind, are a bit more endurable, can fly, and don't need to be bitten to spread -- it happens via {{Nanomachines}} after their victim dies. Bonus points for the Mistress fitting various characteristics of a [[OurLichesAreDifferent Lich]], one of the typical creators of zombie armies.

* TooDumbToLive: The most basic security procedures would've kept Osgood from being killed. Osgood does her research on Missy's device ''ten feet'' from where they're holding said psychotic Time Lady prisoner, despite knowing exactly who she is and [[Recap/DoctorWhoS9E3TheSeaDevils how human prisons means nothing to her]].
