18	-->-- '''The Doctor''' begins JumpingOffTheSlipperySlope
19
20	JustForFun/{{The one w\|ith}}here the Doctor goes too far, gets quite frightening... and is forced to snap out of it [[MyGodWhatHaveIDone in the worst possible manner.]]
21	----
22	The Doctor steps out onto the surface of Mars, wearing [[Recap/DoctorWhoS28E8TheImpossiblePlanet a very]] [[Recap/DoctorWhoS29E742 familiar]] space suit. He's come to Mars on a whim, and quickly finds himself looking upon a human colony called [[Music/DavidBowie Bowie Base One]] (looks like there really is [[Music/HunkyDory life on Mars]]). He's captured right away, though, by a [[RobotBuddy little robot]] called Gadget and taken to see the person in charge of the base: Captain Adelaide Brooke.
23
24	The Doctor thinks that the cutesy robot is rubbish (although robot ''dogs'' are cool, of course), but otherwise loves the base. It doesn't take long for the Doctor to realise exactly where he is, and ''when'': November 21[-[[superscript:st]]-], 2059. Captain Brooke and her crew are the first human colony on Mars. The Doctor is a huge fan of their trip, and as he rambles through their history while madly {{squee}}ing, we see flashbacks to a series of articles with obituaries. The crew will die here today. The Doctor knows it -- and knows that he shouldn't interfere, because this is a tremendously important fixed point in time. He'll never know what kind of monster attacked them, but that's fine, and he'll just leave now.
25
26	People go missing. One by the name of Andy is already transformed. Another, Maggie, is found conked on the head and taken off to the medical dome. The Doctor should leave now. But he lets himself be roped into the investigation by Adelaide, into the bio-dome, joined by [[RedShirt Expendable Crewman]] Tarak. Within a good few minutes, Tarak is separated from the Doctor and finds what appears to be Andy... water flowing off of Andy like he's a theme park ride. Andy's face is distorted, cracked and gushing water.
27
28	The Doctor keeps making vague excuses about how he has to go.
29
30	Maggie, deep in an isolation room, also shows signs of... whatever this is. She's freaking out the base's nurse, Yuri. He contacts Adelaide, and she realises it's best to leave the dark, scary giant building with lots of places for something to jump out at them. But they make one last look around for Tarak... and find him in the same water-zombie state as Andy, who is standing right next to him, or what used to be him. Dragging Adelaide away, the Doctor announces it's time to run, and they barely escape the two infected humans.
31
32	They lock the two infected forms out of the main central dome. These water creatures, Maggie included, are demanding to go to Earth -- where they can thrive in water. The Doctor raises up the question of who ''else'' is infected, if the virus/parasite/whatever isn't inside everyone else on the base already, as it thrives in the water and obviously came from the Martian water that everyone has been drinking. Adelaide goes off to check the ice cap on top of which the base is built, while the rest of the crew begin prepping for escape to Earth. The Doctor knows that he should be ''leaving'', but he decides to run off and join Adelaide instead, seeing as he can't leave without his spacesuit.
33
34	At the ice cap water extraction dome, the Doctor and Adelaide look out over a rather impressive ice cap while the Doctor rambles about [[ContinuityNod some old enemies of his]] -- the Ice Warriors. Adelaide begins to question the Doctor about why he's so eager to leave and how he knows so much about the Mars colony. The Doctor explains that this is a "fixed point in time", confusing the hell out of Adelaide for a few moments before the Doctor quickly changes the subject to ''why'' Adelaide came out into space: [[Recap/DoctorWhoS30E12TheStolenEarth The Dalek Invasion of 2009]][[labelnote:*]]"Present day" episodes in the Russell T. Davies era were usually a year ahead of their broadcast dates. "The Stolen Earth" was broadcast in 2008 and set in 2009. https://tardis.wiki/wiki/Planetary_Relocation_Incident[[/labelnote]]. She looked into the eyestalk of a Dalek, it looked right back, and left her to live. Adelaide simply wished to follow that Dalek out again -- not to kill it, but to meet other creatures in peace.
35
36	The Doctor rambles on about how awesome Adelaide's descendants will be, all inspired by her heroic journey to Mars, and how massively important they'll all be to the future of all time and space. More newspaper flashbacks. It freaks the hell out of Adelaide in general. In seconds, it's revealed that everyone else still alive doesn't have the virus -- so it's time to start leaving!
37
38	...or it would be, if the infected bodies that were once Andy and Tarek didn't climb up on top of the central command building to start spewing water everywhere.
39
40	The Doctor, now with space suit, finally starts to leave... but Adelaide refuses to open up the airlock hatch until the Doctor explains why he's being so awkward around everyone. He explains it all for us (and Adelaide): ''this very day'' is the day that Bowie Base One is destroyed with all hands lost. Adelaide's heroic death is what will inspire her descendants and what will propel humanity into interstellar travel. It has to happen.
41
42	The Doctor leaves solemnly, listening through his helmet to the attempts of the remaining crew to fight fate the best they can. He hears about the water seeping into the main control room, taking out another member of the crew. Yet another is infected as a single drop hits his face -- and this one demands the crew leave him before he's infected. The pilot of the shuttle, Ed, is also infected -- but [[HeroicSacrifice chooses to blow up the shuttle]] rather than let the Earth get infected. The resulting explosion traps our remaining three crew members in a single storage room, and knocks the Doctor quite a good distance.
43
44	All looks grim for Adelaide, Yuri and Mia... until the Doctor walks into the storage room, shouting out orders like a maniac and trying to save those people he'd declared dead. Adelaide begins to panic, wondering why the Doctor is throwing his previous worries out the window. Almost foaming at the mouth, the Doctor launches into a speech about how there are laws of time, but he can warp them. He's safe, he knows it's not his time yet, because he'll be killed when someone knocks four times. So today, he's decided that as many people as possible are going to be safe too! The laws of time that were once enforced by a group of people -- a group long since dead:
45
46	->'''The Doctor:''' Do you know who that leaves? ME! It's taken me all these years to realise it, [[BadassBoast but all those laws of time are mine]]. '''[[AGodAmI And they will obey ME!]]'''
47
48	Adelaide believes that the Doctor's gone insane. [[SarcasmMode Gee, whatever gave her that idea?]] The Doctor declares he's also ''fighting time itself''. Not even close to giving up, the Doctor finds that robot buddy Gadget in storage and uses it to bring the TARDIS to him -- even while Adelaide sets the base to self-destruct. With four seconds to go, the TARDIS begins to rematerialise. As it finishes, the countdown reaches zero, the base blows up and the TARDIS whisks everyone away.
49
50	The Doctor takes the survivors to Earth: same time, same day. Mia, unlike many companions of the past, ''utterly freaks out'' at the TARDIS itself and flees -- Yuri running after her. The Doctor himself is all grins and smiles, proudly proclaiming how time now obeys him. In recognition of his new exalted status, he gives himself the new title of [[AGodAmI Time Lord Victorious]]. Not only did he save two of the "little people", but he also saved one of the "big ones".
51
52	Adelaide does not take this well, trying to reason with the Doctor -- claiming that no one person should have so much power. However, she just cannot get through to him, as the Doctor is finally realising everything that he can do, all that he can accomplish. He can warp time, escape death, [[ArsonMurderAndJaywalking open up the door to Adelaide's home]].
53
54	Adelaide simply glares at the Doctor and enters her own home. A blue flash through her windows [[DrivenToSuicide makes it perfectly clear just how the Doctor's hubris will be repayed]].
55
56	Thoughts flash through the Doctor's head of reading about Adelaide's once noble death, and that of the two crew members who originally didn't make it. They begin to change, and his face gleams with horror. His fond memories of Bowie Base One's sacrifice have been rewritten... for the ''worse''. The Doctor breaks, [[MyGodWhatHaveIDone realizing that he's gone too far]]. [[Recap/DoctorWhoS30E3PlanetOfTheOod Ood Sigma]] appears for a moment, and the Doctor questions him, wondering if this is when he's supposed to die.
57
58	Ood Sigma simply vanishes, leaving a distressed and panicked Doctor to dash into the TARDIS and lock the door behind him. The Cloister Bell begins to go off, but the Doctor declares "No" and valiantly throws himself into his final episode.
59	----
60	This episode is considered one of the best in the Tenth Doctor's era, and played a key part in the story of ''[[Franchise/DoctorWhoExpandedUniverse Time Lord Victorious]]'', a [[CrossThrough multi-platform event]] spanning the books, comics, a web series, the [[AudioPlay/BigFinishDoctorWho audios]] and interactive experiences. For the Tenth Doctor this event takes place immediately after this episode and shows him continuing down the dark path he started while his [[Characters/DoctorWhoEighthDoctor Eighth]] and [[Characters/DoctorWhoNinthDoctor Ninth]] incarnations try to stop him.
61
62	----
63	!!Tropes:
64
65	* TwentyMinutesIntoTheFuture: The home time period of Adelaide and her subordinate crew and family. Born in the late 1990s, her 60-year-old self (as seen throughout most of the special) lives during the 2050s.
66	* AbandonShip: The crew makes a hasty attempt to bug out, but Maggie [[DangerTakesABackSeat gets in the shuttle]] and infects Ed before he can lock her out. So he sets the SelfDestructMechanism before the infection takes, blowing up the shuttle.
67	* TheAestheticsOfTechnology: Although the Doctor is using a spacesuit from humanity's future, it doesn't look like it, making the comment on its advanced technology a bit odd. Presumably this is because it's more lightweight and noticeably less bulky than the suits they're using, which may be why they wonder where it came from.
68	* BadassNormal: Captain Adelaide is just a normal human, which makes how she endures the events of the episode stand-out more.
69	* BeCarefulWhatYouWishFor: Though The Doctor does start to go mad over helping her and the other survivors, it was Captain Adelaide who begged for him to intervene and save her and the others in the first place, before she has a sudden case of buyers remorse.
70	* BelligerentSexualTension: It's heavily implied that something may have gone on between Adelaide and Ed that ended very badly, hence why their relationship is extremely tense. Ed specifically mentions how Adelaide "could never forgive [him]" over something before he dies.
71	* BigBad: The Flood.
72	* BigDamnHeroes: The Doctor's return to save Captain Adelaide, Yuri and Mia from the Flood, [[ComplainingAboutRescuesTheyDontLike whether the Captain wants it anymore or not]], complete with dramatic lighting and music.
73	* BodyHorror: The people infected by the Flood become water-bloated, ruptured-skin-sporting, dead-eyed monstrosities.
74	* BoldExplorer: Captain Adelaide's the commanding officer of [[SettlingTheFrontier humanity's first permanent Mars colony]]. Her granddaughter also looks forward to following in the footsteps of the trope and become a space explorer as well.
75	* BorrowedCatchphrase: The Doctor in the midst of his HeelFaceTurn uses the Master's "You will obey me," but applies it to the laws of time.
76	* BreakTheHaughty: Adelaide does this to the Doctor after his behaviour horrifies her and disgusts her. And what she does leads to a massive Tear Jerker, though one that helps the Doctor snap out of his creepy delusions of grandeur.
77	* BrickJoke: "You were right, Doctor: bikes."
78	* BurningRubber: Gadget leaves flaming tracks after the Doctor soups it up.
79	* CallBack:
80	** To "[[Recap/DoctorWhoS30E2TheFiresOfPompeii The Fires of Pompeii]]", the last time fixed points in time were mentioned. He also used the TARDIS to save a couple of people at the last minute in that episode, although this time it is ''not'' shown as a good thing. He rehashes the argument he had with Donna in that episode, then says everything he does to try to help just makes it happen, when trying to convince Adelaide to let him leave.
81	** The Doctor is wearing the spacesuit from Sanctuary Base 6, as seen in "[[Recap/DoctorWhoS28E8TheImpossiblePlanet The Impossible Planet]]".
82	** When the shuttle explodes, several of the Doctor's lines about the Time Lords from the last several seasons are repeated as he stares at the wreckage.
83	* TheCaptain: Adelaide is very much in charge of her base and ship.
84	* ChekhovsGun: Gadget the robot gets used as a high-speed Segway by the Doctor and Adelaide to escape the infected crew members, and later is used to bring the TARDIS to the Doctor and remaining crew on the ship.
85	* ChronicHeroSyndrome: Really gets to the Doctor in this episode. The Bowie Base One disaster is a fixed event, and as such he would've been more rational and just left right away, but Adelaide forces him to get just involved enough to let his heroic instinct get to him.
86	* ComplainingAboutRescuesTheyDontLike: Captain Adelaide tearfully begs the Doctor to break the rules and intervene and save her and the others, and [[ConscienceMakesYouGoBack when he finally does]] she suddenly has nothing but complaints about it and him when they get back to Earth.
87	* TheConscience: Adelaide acts like this to the Doctor, especially in the last scene, where she calls him out for breaking his principles and playing around with historical outcomes and the fates of individuals as if he had the right to do so. Captain Brooke might be icy and strict to him, but she's open to admiring him, as long as he keeps to his ethics and doesn't succumb to delusions of AGodAmI.
88	* ConscienceMakesYouGoBack: The Doctor is unable to resist Adelaide's pleading for him to save her and her crew, especially listening in as the Flood murders them one by one, and breaks the rules in an attempt to do so.
89	* ContinuityNod: Given that they have a good 45 years to work with, this is to be expected...
90	** The Doctor mentions the Ice Warriors, and the humans regard the idea of a sentient race once living on Mars with skepticism.
91	** This isn't the first time this Doctor has met a [[Recap/DoctorWhoS28E3SchoolReunion "funny robot," but likes robot dogs.]] Is it at all possible that was a slam against Kamelion?
92	** The Philippines is strongly implied to be a world power by this point. Those who recall [[Recap/DoctorWhoS14E6TheTalonsOfWengChiang a certain Fourth Doctor serial]] should know that [[UsefulNotes/FilipinosWithFirearms it will get much more powerful in the future]].
93	* CoolOldLady: Adelaide is of the ReasonableAuthorityFigure mould. While she gets to know the Tenth Doctor only for a short time, he fails to intimidate her even when he goes off on his unnerving MotiveRant about enjoying the thought of becoming the Time Lord Victorious.
94	* CreatorProvincialism: Subverted, for once; though there seem to be a disproportionate number of Britons around (and the base is named after a [[Music/DavidBowie British musician]]), there is a realistic international representation, including the major space powers of the United States and Russia. Many countries that are currently not too important on the world stage are described as being major powers after an "oil apocalypse" [[NoodleIncident which is never really explained]] (it only gets a brief mention from Adelaide in which she describes that the human race was almost wiped out). Two of these are Spain and the Philippines.
95	* CuteMachines: Gadget, specifically described as a “funny robot”.
96	* DangerTakesABackseat: How Ed and the shuttle are lost; Maggie slips in behind him.
97	* TheDeterminator: Adelaide ''never'' snaps, no matter what she comes face to face with..
98	* DetrimentalDetermination: The story picks apart the Doctor's relentless drive to save as many people as he can by showing what happens when that desire runs into conflict with laws of time that prevent altering fixed points -- in this case, the death of an entire scientist colony when their base on Mars mysteriously explodes. Without a companion to provide a MoralityChain, the Doctor, having grown tired of the constant death and destruction he's seen throughout his life, declares himself the [[AGodAmI "Time Lord Victorious"]] and gets three members of the crew off the base and back onto Earth. However, all of them are terrified by him in the end, and Adelaide shoots herself out of disgust towards the Doctor, ensuring that the aftermath of the explosion will happen as time dictates, just under modified circumstances. The Doctor immediately has an immense MyGodWhatHaveIDone moment and flees in both fear and anguish.
99	* DidntThinkThisThrough: PlayedForDrama: After managing to rescue Adelaide, Mia and Yuri from Mars, the Doctor considers this to be a sign that he should ''keep being'' the "Time Lord Victorious", as he feels he can now directly influence history, saving influential figures along with "some little people". It takes Adelaide [[DrivenToSuicide shooting herself at the first opportunity]] for him to snap out of it.
100	* DoNotGoGentle: The Doctor refuses to let these people, little or otherwise, die without a fight.
101	* DownerEnding: While the Doctor manages to save three people, this episode is completely devastating otherwise. The Doctor almost completely loses his mind, going the farthest in extreme alteration that he had ever gone and is left broken and horrified by the realization of his actions after Adelaide decides to kill herself to preserve the timeline, and he glances to see an omen from an Ood indicating that his time to die has come.
102	* DugTooDeep: There was something living in the ice that TheTeam dug up for drinking water.
103	* DwindlingParty: Captain Brooke's crew of eight succumbs to the virus until only two are left.
104	* EldritchAbomination: Via [[OurZombiesAreDifferent parasites in the Martian water that turn people into craggy, water-spewing zombies]] with unholy screams that can free the ''real'' EldritchAbomination hiding deep within the ice.
105	* EvenEvilHasStandards: Daleks will literally kill everything and anything in existence that is different to them if they can; however, messing with a fixed-point in time is something that not even ''they'' will do, and thus a Dalek actually spares a young child -- Adelaide -- when it comes across her.
106	* EverybodyDiesEnding: Everyone human in the base will die; it's a Fixed Point in Time and thus a ForegoneConclusion. Except this trope is defied when the Doctor saves three of them! Yes, Adelaide kills herself, but Yuri and Mia are still alive at the end.
107	* ExtyYearsFromPublication: The story takes place on 21 November 2059. RTD gambled on the episode airing on 21 November 2009 and lost (it aired six days earlier, on a Sunday rather than in the show's usual Saturday slot), but it's close enough.
108	* FaceRevealingTurn: The background music swells as Tarek approaches the now-infected Andy and he turns his face to the camera.
109	* FamousNamedForeigner: Yuri Kerenski brings to mind Alexander Kerensky, the last leader of the Russian Duma before the October Revolution.
110	* FireWaterJuxtaposition: This episode is a SpiritualAntithesis to "[[Recap/DoctorWhoS30E2TheFiresOfPompeii The Fires of Pompeii]]" with a parallel title and an alternative exploration of the same themes, featuring water monsters instead of magma monsters.
111	* FiveSecondForeshadowing: When Adelaide heads into her house we see her draw her pistol. Had the Doctor been paying attention to her instead of ranting to himself, he might have stopped her from killing herself. Then again, if he had been paying attention to her ''at all'' he would have realised how distraught she was and possibly got the idea that going AGodAmI on her was a bad idea.
112	* {{Foreshadowing}}: During his AGodAmI stage, the Doctor starts acting like the Time Lords who appear two episodes later (same ScrewTheRulesIMakeThem personality). He also uses some of the Master's quotes. Guess who also shows up in the next episode?
113	* ForgotICouldChangeTheRules: PlayingWithATrope. At first the Doctor is all "I shouldn't be here; I should leave" because he can't change the rules. Then he decides that, as the last of the Time Lords, yes, he ''can'' change the rules. So he meddles and then he realizes that while he can change the rules if he wants, there's a ''reason'' why they were the way they were. Upon this realization, he states "I've gone too far."
114	-->'''The Doctor:''' The laws of time are mine! And ''they will obey me!''
115	* ForWantOfANail: Everything could have been avoided but for a single water filter that failed (and not having anything to replace it with, because the spare filters they'd brought didn't fit).
116	* FreezeFrameBonus: The Doctor makes a big deal out of the fact that Mia is "only 27 years old." However, if you look at all the articles shown about the other members of the crew, Yuri is also 27 and Roman is 25. For Roman's, it's pointed out in the article that he is the youngest member of the crew. Presumably, he only focused on her because she was in his field of vision when the realization everyone on the base was going to die that day sank in.
117	* FriendlyEnemy: The Doctor and Adelaide act mildly antagonistically to each other, but this is purely down to her not entirely trusting his approach and ideas and the Doctor not being too keen on her paying close attention to his methods.
118	* GlassShatteringSound: The zombies' roars cause the glacier to crack.
119	* AGodAmI: The Doctor starts thinking of himself as the Time Lord Victorious and talking in such a way that suggests he thinks all of time and space is going to bend to his will. For those who didn't get the point, bear in mind that the Doctor's comment about how the laws of Time will obey him is eerily similar to the Master's old [[CharacterCatchphrase catchphrase]] of "I am the Master, and you ''will'' obey me!"
120	* GoMadFromTheRevelation:
121	** A subtle execution of the trope -- but it certainly applies when the Doctor realises he changed nothing at all in the long run, in spite of his efforts.
122	** Despite what the entry below says, maybe Adelaide Brooke wasn't a HeroicSacrifice at all; maybe she just freaked out at the thought of a sappy eccentric guy playing God and saving peoples' lives based on simply whether they are important or not.
123	* HumanoidAbomination: The infection in the water turns anyone afflicted by it into humanoid, dead-eyed water fountains functioning as nothing more than a LivingBodysuit for some ancient horror buried under the ice.
124	* HeroicSacrifice:
125	** In the original timeline, Adelaide Brooke detonates the Mars base to save Earth from the Flood. In the altered timeline, she kills herself in an attempt to keep her family's future history on track and save the universe from the Time Lord Victorious.
126	** Ed detonates the rocket to stop the Flood from reaching Earth when he realises that it's on board and has infected him.
127	* HeroicSuicide: In the end, Adelaide does it as a defiant gesture of resistance against the Doctor's increasingly deranged toying with the idea of shedding responsibilities and changing history in whatever way it pleases him, shocking him out of going down an increasingly slippery path of acting as the overlord of all Time-Space. She can clearly see the damage he could do in the future if his ego were allowed to run unchecked.
128	* HypocriticalHumour: "I don't like funny robots." As well as "Oh, well robot ''dogs'' are different!"
129	* InSpiteOfANail: InUniverse example: Adelaide commits suicide on Earth rather than dying on Mars, but not much of humanity's future is changed.
130	* ItCanThink: Those infected by the contaminated water are not stupid, they even managed to short out the systems of an airlock to bust it open.
131	* InvincibleBoogeymen: While Flood hosts can be slowed down, nothing in the long run can stop them - as the Doctor puts it, "water always wins." One by one the crew of "Bowie Base One" on Mars become infected, as only one drop of water is all that takes to convert someone.
132	** Although it is played with in that weapons are never used against them, so we don't know if they are invincible or not for certain. Fire and flamethrowers likely could have worked well against the water based creatures. The Ice Warriors at least showed how effective freezing them was, and the Doctor showed that electricity injured them.
133	* {{Irony}}: After all the complaining about being saluted, the Doctor salutes Captain Brooke.
134	** The Doctor is usually all about saving people's lives. Here, his ChronicHeroSyndrome ends up backfiring ''hard.''
135	** The Dalek who spared Adelaide's life is actually more respectful of fixed points in time than the Doctor is this episode.
136	* JerkassHasAPoint: Despite how unhinged the Doctor becomes over breaking the rules, [[BeCarefulWhatYouWishFor Captain Adelaide DID beg for his intervention]], and doing so does save her, Yuri and Mia by the end of the episode, where before in the original timeline everyone at the base died. Even after her suicide, Yuri and Mia are still alive thanks to him.
137	* JumpingOffTheSlipperySlope: The Doctor begins to do this at the end, with a truly terrifying MotiveRant.
138	-->'''The Doctor:''' There are laws, laws of time. And once upon a time there were people in charge of those laws, but they ''died!'' All of them died! And do you know who that leaves? ''ME!'' It's taken all these years to realise it, but the laws of time are ''mine'' and they ''will OBEY ME!''
139	* KirkSummation: Adelaide gives a brief but effective one to the Doctor after he interferes in events that could radically alter the future of the Earth and her own family.
140	-->'''Adelaide:''' But... Susie... my granddaughter... wasn't she supposed to become... we'll never exist now.\
141	'''The Doctor:''' Nah, Captain Adelaide can inspire her face-to-face. [[TemptingFate Different details, but the story's the same.]]\
142	'''Adelaide:''' You can't know that! And if my family changes... the whole of history could change! The future of the human race! No one should have that much power!\
143	'''The Doctor:''' Tough.\
144	'''Adelaide:''' ''[backs away from the Doctor, unsure of what is going on]'' You should have left us there.\
145	'''The Doctor:''' Adelaide, I've done this sort of thing before. In small ways, saved [[{{Muggles}} some little people]]. But never someone as important as you. ''[[[SlasherSmile does an insane grin]]]'' [[{{Pride}} Ooh, I'm good!]]\
146	'''Adelaide:''' ''[shocked]'' Little people? What, like Mia and Yuri? [[WhatTheHellHero Who decides they're so unimportant? You?!]]\
147	'''The Doctor:''' For a long time now, I thought I was just a survivor, but I'm not. I'm the winner. That's who I am. [[{{Ubermensch}} A Time Lord Victorious]].\
148	'''Adelaide:''' And there's no one to stop you?\
149	'''The Doctor:''' [[SmugSuper No.]]\
150	'''Adelaide:''' ''[noticeably angry]'' This is wrong, Doctor! I don't care who you are! [[TheConscience The Time Lord Victorious is wrong!]]\
151	'''The Doctor:''' [[ShutUpKirk That's for me to decide.]]
152	* KnightTemplar: The Doctor declares that he is the master of Time and he can do whatever he wants to make history go the way he wants so he can save whoever he wants. You don't like it? "Tough."
153	* LargeHam: The Doctor gets into a loud and erratic fit of heroics at the episode's climax.
154	* LittleNo: The last line of the episode, from the Doctor, in response to the Cloister Bell ringing as a result of both his recent actions and [[Recap/DoctorWhoS30E17E18TheEndOfTime events yet to come]]. He's not ready to die yet.
155	* MakingASplash: The unidentified parasites live in water and can generate water and shoot it at high pressure.
156	* UsefulNotes/{{Mars}}: The question of what is wrong with the water on Mars is pivotal to the plot.
157	* MeaningfulBackgroundEvent:
158	** Andy bites a carrot, then the shot changes to focus on Maggie. He remains out-of-focus in the background, convulsing and suddenly falling still.
159	** Same thing happens to Maggie later, with Yuri in the foreground.
160	* MeaningfulEcho: It's pretty clear how far off the deep end the Doctor's gone when he starts echoing the Master's [[CharacterCatchphrase catchphrase]] from the classic series.
161	-->'''The Doctor:''' And they ''will'' obey me!
162	* MirrorCharacter: Many an IronicEcho abounds when the Doctor starts to snap and unknowingly begins to channel the Master.
163	* MoralityAdjustment: The Doctor briefly becomes a KnightTemplar, declaring that he can do whatever he wants with the Laws of Time in name of saving whoever he wants. Adelaide straight up calls him a power-mad despot.
164	* {{Muggles}}: A DefiedTrope on Adelaide's part. She objects to the Doctor's not-so-subtle insinuations that he rescued her from death for being "more historically important" than any of her crew members, just because she holds a higher rank than them and is more publicly famous in her own time.
165	* MultinationalTeam: The astronauts on the base. Several British and American, a German, a Russian, a Pakistani and an Australian and whatever Mia was; FreezeFrameBonus told us she was Korean-American (there's a South Korean flag sticker on one wall and her obituary said she was born in Houston and studied in Stanford), but Creator/GemmaChan doesn't put on an American accent (and possibly didn't know she needed to. The obituaries were likely made during post-production; it's possible that they made the decision to have Mia be from Texas long after filming).
166	* MurderWater: Water which turns you into a bloated malevolent water-spewing being seconds after coming in contact with a single drop.
167	* MyDeathIsJustTheBeginning: Adelaide isn't particularly happy to hear that she's going to exemplify this trope, but comes to embrace it after the Doctor saves her so that her granddaughter can help lead Earth into space.
168	* MyGodWhatHaveIDone: Going hand-in-hand with GoMadFromTheRevelation, when the Doctor realises he let his arrogance go to his head.
169	-->"''I've gone too far.''"
170	* NameOfCain: Maggie's full name is shown in the personnel files to be Margaret Cain. Not only is she one of the first people to be infected, but she appears to act as the ringleader of the infected crewmembers.
171	* NeverFoundTheBody: No trace of either of Adelaide's parents was ever found. Which, considering they disappeared during the Battle of the Medusa Cascade, would seem to indicate that they ended up becoming victims of the Reality Bomb test.
172	* NiceJobBreakingItHero: Several violators here. The TARDIS for bringing the Doctor to a fixed point, the Doctor for not leaving at the first opportunity, and Adelaide for not letting him leave immediately.

175	%%%%
176	%%%%%%
177	%%%%
178	* NeverTrustATrailer: One of the trailers shows the Doctor mentioning the prophecy from the previous special ("he will knock four times"), just before some knocking starts. In the actual episode, it's only one of the water creatures and it only knocks three times.
179	-->'''The Doctor:''' And three knocks is all you're getting!
180	* NoJustNoReaction: Mia does not take well to the TARDIS's AlienGeometries on top of everything else that has happened this day.
181	* NoMoreHoldingBackSpeech: The whole of the episode, the Doctor struggles with the taboo of changing Fixed Points in history, how his attempts to save them might doom then instead, and how he's only ''one'' Time Lord because the others are all gone. Then he realizes that, as the last Time Lord, he is the Time Lord Victorious, so if he wants to save these people then he's going to and no one's going to stop him!
182	* NoodleIncident: Some incident to inspire animosity between Adelaide and her number two is alluded to but never elaborated on.
183	-->'''Ed Gold:''' ''[last words before sacrificing his life after being infected]'' Hated it, Adelaide! This bloody job. You never gave me a chance... you never could forgive me.
184	* NoOSHACompliance:
185	** Whoever decided that a room that was meant to ''quarantine'' people should have a ''basic'' seal and not a Hardinger Seal clearly didn't understand why an unbreakable seal would help to keep something ''contained''.
186	** Whoever built the water system recognized the risk of water contamination and included filtration, but they packed the wrong filters for the water system.
187	* NothingIsScarier: It is never revealed where the Flood came from, with available evidence making it equally likely that the virus was natural or some artificial creation made by the ancient Ice Warriors, particularly since a host responded to the Doctor talking to it in Ancient Martian.
188	* OhCrap:
189	** There are several moments of this throughout the story, considering only ''one'' drop of water can infect someone.
190	** The biggest one is at the end, though: the Doctor, on his way back to the TARDIS, loses it when he realises Adelaide has killed herself, and it dawns on him what he just tried to do.
191	** One last one when the Cloister Bell goes off.
192	* OmniscientMoralityLicense: The Doctor becomes so overwrought with the guilt and fear that everyone is supposed to die in the expedition that he ''snaps'' and saves the three remaining members whom ''he himself'' categorises as two "little people" plus one "big person". He declares himself "[[AGodAmI Time Lord Victorious]]", and says there's nothing anyone can do to stop him. Then Adelaide, who is quite frankly disgusted with this notion, ''does'' stop him by committing suicide, ensuring that her descendants lead the human race outside the cosmos, and the timeline is somewhat fixed. It took this for the Doctor to realize that his hubris had ''[[MyGodWhatHaveIDone completely]]'' [[MyGodWhatHaveIDone got the better of him]].
193	* OOCIsSeriousBusiness:
194	** Adelaide paying someone a compliment is noted to be a bad sign.
195	** The Doctor going Time Lord Victorious is awesome, and ''scary''. Also, his solution to the problem is to use the TARDIS, something he almost ''never'' does.
196	** The fact that a ''[[OmnicidalManiac Dalek]]'' decided to spare Adelaide shows how important not messing with fixed points in time is.
197	** For the first time, the Doctor says he sometimes saves "one of the little people", rather than talking about how important everyone is.
198	* OohMeAccentsSlipping: Creator/DavidTennant slips into a neutral posh English accent quite a lot. He had been playing Theatre/{{Hamlet}} with the Royal Shakespeare Company for months, to the point where Hamlet's posh accent had eclipsed the Doctor's as his default English accent. He claims he had to buy all the [=DVDs=] and watch his performance again to relearn how to do it. Of course, the Doctor loses his handle on reality and declares himself to be a god, so his accent going up two social classes seems to suit his {{hubris}}.
199	* OurZombiesAreDifferent: The Flood turns humans into water zombies. They've got the creepy eyes and the infected status, but absolutely no ZombieGait. A single drop of water is enough to turn someone into a PlagueZombie. The sentient, waterborne [[TheVirus Virus]] the Flood turns the infected hosts somewhat into {{Technically Living Zombie}}s (they retain a decreased heartbeat), but it seemingly effectively kills or consumes the host's original mind and personality entirely, leaving only the HiveMind of the Flood virus PossessingADeadBody (or rather possessing an empty shell). The Flood makes the hosts produce copious amounts of virus-carrying water from their orifices and their skin (which they breathe in place of air), their eyes might change color, the skin around the mouth becomes cracked-looking, and the host exhibits an internal fission which blackens the teeth and enables them to survive in Mars' freezing conditions. What's more, due to the virus' sentience, it can choose to delay taking over an infected host if it wishes whereas usually it takes over within a matter of seconds. Oh, and the zombies can run faster than you...
200	* OutOfCharacterMoment: During the final scene, the Tenth Doctor shows a very selfish side unlike his usual compassionate attitude. He argues with Adelaide that he gets to decide who's important and who's not, who gets to live and die, and calls himself a winner in a tone similar to how the famous Creator/CharlieSheen calls himself a winner. When Adelaide calls him out saying he's wrong, he simply replies, "That's for me to decide." This is portrayed as what the Doctor is like if he's both wracked with guilt and loneliness for a long time and left without [[MoralityChain a companion to regulate him]]. By the end he's given a sharp wake up call about just how OOC he's being and it's the start of him realizing that he needs to regenerate because he's becoming dangerously prideful from being 10 for so long. Made even more alarming when you realize that, at the time of his regeneration, 10 lived less than a decade. As the Eleventh Doctor would [[Recap/DoctorWho2013CSTheTimeOfTheDoctor later put it]], he had "vanity issues" which caused him an abnormal amount of attachment to a specific incarnation and fear of regenerating.
201	* PokemonSpeak: Gadget Gadget!
202	* PragmaticVillainy: That Dalek didn't kill young Adelaide because it knew that her achievements as an adult were a Fixed Point, and subverting one will cause all of reality to fall apart, which would annihilate the Daleks as well.
203	* PreAsskickingOneLiner: "I don't hear anyone knocking!" ... knock... knock... knock "Three knocks is all you're getting!"
204	* RealLifeWritesThePlot. When the bio-dome scenes were being shot, the film lights woke up the birds, and a line was added to the script to explain the birdsong.
205	* RedHerring: After seeing that Maggie's eye colour did not change with the rest of her, the Doctor briefly theorises that she may have retained some of her humanity. However, the opposite turns out to be true, as she actually becomes the nearest thing that the story has to an individual BigBad.
206	* RiddleForTheAges: What were the Flood trying to release from the Glacier near the end?
207	* RippleEffectProofMemory: Yes and no; the Doctor's memories of history change at the end, but he seems to be aware that they've changed, and from what.
208	* RobotBuddy: Gadget was made from a drone, and his handler Roman is fond of him.
209	* RunningGag:
210	** The Doctor's insistence that they should have brought bikes. It's a LampshadeHanging on the amount of running that goes on in this show.
211	** The Doctor commenting that he really ''should'' go.
212	* SanitySlippage: The Doctor isn't accurately described as "sane" on his better days, but the effects of travelling alone for too long, coupled with hearing the cries of the dying astronauts over the radio, drive him into an ''incredibly'' disturbing [[AGodAmI moment of arrogance]].
213	* ScrewTheRulesImDoingWhatsRight: With the crew screaming, panicking, and on the verge of death, how could the Doctor ''not'' help them, regardless of the Laws of Time?
214	* ScrewTheRulesIMakeThem: The Laws of Time? The only such laws are those that the Time Lord Victorious decrees! ...Keep in mind that he believes this only because he's the last of the Time Lords.
215	* SealedEvilInACan: Humans accidentally released Sealed Evil in a Glacier when they tap it for water.
216	* SelfDeprecation: Again, the Doctor [[Recap/DoctorWhoS28E3SchoolReunion "doesn't like funny robots"]]. He avoids self-deprecation later on by saying that robot dogs are different, making it closer to HypocriticalHumour.
217	* ShoutOut:
218	** The first human base on Mars is called Bowie Base One. There's a Music/DavidBowie song called [[Music/HunkyDory "Life on Mars?"]].
219	** It's the wrong Bowie song, but the line "Planet Earth is blue, and there's nothing I can do" from "Music/SpaceOddity" seem significantly reflected in this episode (not to mention the event of someone dying in space for reasons never known back on Earth).
220	** When the Doctor changes history, we see [[Franchise/BackToTheFuture news entries with changing text]]. Not to mention the [[Franchise/BackToTheFuture flaming tire tracks]].
221	** The sound the computer makes when it tracks the crew members is from ''Film/TwoThousandOneASpaceOdyssey''.
222	** The horrific alien zombie virus is called [[Franchise/{{Halo}} the Flood]].
223	** A member of the crew is infected by the virus when [[Film/TwentyEightDaysLater a drop of the tainted liquid hits their eye]].
224	** The door that leads into the comm room where Adelaide contacts the Doctor closes with the [[DoomDoors same sound effect]] as the doors in the video game ''VideoGame/{{Doom}}''. Fitting, given that the story revolves being possessed by supernatural forces in a creepy facility on Mars.
225	** The idea of one drop of water contaminating the global water supply may have been borrowed from Creator/KurtVonnegut's ''Literature/CatsCradle'', in which a similar plot device causes the world's entire water supply to turn into ice-nine, bringing about a planetary ApocalypseHow that is implied to cause the eventual extinction of all life on Earth.
226	** An EldritchAbomination that takes the form of a watery liquid that turns people into zombies who want to bring about TheEndOfTheWorldAsWeKnowIt sounds a lot like the modus operandi of the title monster from John Carpenter's ''Film/PrinceOfDarkness''.
227	** A man shocking his male lover by buying him a car as a surprise birthday present, now [[Series/QueerAsFolkUK where have we seen that before?]]
228	* ShutUpHannibal: The Doctor delivers one of these to the infected Andy Stone who is banging on the door in a deliberate attempt to taunt the Doctor regarding the "four knocks" meaning his death.
229	-->'''The Doctor:''' No, 'cos someone told me just recently, they said I was going to die. They said, "he will knock four times", and I think I know what that means, and it doesn't mean right here, right now, 'cos I don’t hear anyone knocking, do you? ''[The Flood-possessed Andy, in response, knocks three times on the door in response]''\
230	'''The Doctor:''' Three knocks is all you're getting! ''[[[HighVoltageDeath he electrifies the door; Andy is blasted back, screaming in pain]]]'' Water and electricity: bad mix!
231	* SilentAntagonist: The Flood only says a few brief lines very early on. From then on, the victims don't say a word.
232	* SlasherSmile: The Doctor briefly adopts one while using Gadget to remotely pilot the TARDIS.
233	* SpiritualAntithesis: To "[[Recap/DoctorWhoS30E2TheFiresOfPompeii The Fires of Pompeii]]". Leaving aside the [[FireWaterJuxtaposition juxtaposed titles and monsters]], both stories are about the Doctor traveling to the eve of a world-famous tragedy that's a fixed point in time, which makes him feel helpless to save anyone -- although instead of a past event which actually happened, in this instance it's a fictionalized historical event that happens in the future -- and both stories end with the Doctor finding a way to save the episode's main one-shot characters. However, "The Fires of Pompeii" ended with the Doctor taking a third option where he managed to at least save a minute handful of people without disrupting the grand scheme of history per Donna's encouragement, making him acknowledge that he does indeed need people like her to travel with him and keep him good -- in "The Waters of Mars" on the other hand, the Doctor is alone again, and so he forces himself to walk away and abandon the people doomed to die despite his own protective instincts to the contrary, up until he snaps and he takes a shit on destiny's desk in order to force the cast's salvation while the thought of having power over the laws of time goes to his head. Additionally, whereas "Fires" saw the Doctor outright ''cause'' the historical tragedy in order to stop the MonsterOfTheWeek from establishing an {{alternate timeline}} and destroying humanity, in "Waters", the Flood's efforts to invade Earth are prevented regardless of the Doctor's actions or inaction.
234	* SurvivalMantra: After the Doctor snaps, channels the Master and starts fighting the water: "Not beaten, ''not beaten''."
235	* TeamMom: Adelaide serves as this to her crew, being in her 60s, while the rest are in their 20s-30s (aside from Ed, who is 51).
236	* TemptingFate:
237	** The Doctor when he realises where he is.
238	--->'''The Doctor:''' I should go. I really... should go.\
239	''[hears a roar over the Tannoy]''\
240	'''The Doctor:''' Oh, I really should go...
241	** Later when they are evacuating the base.
242	--->'''The Doctor:''' Right, I should leave! ''Finally''! I ''should'' leave! Yuri my old mate, no, no point in me seeing the icefield? No point at all! No... ''[begins to run after her]'' ADELAIDE!
243	* TheyCallMeMisterTibbs: The Captain, upon being called "boss".
244	* TooDumbToLive: Captain Adelaide and her crew never use their weapons against the Flood to test whether they can be killed or not, with the Doctor playing a part in foolishly talking Adelaide out of even trying.
245	* TrickedOutTime: The Doctor ends up being RightForTheWrongReasons about how history ends up otherwise the same despite some small changes, with Captain Adelaide ensuring that the only things that are different are the circumstances of her death, while Mia and Yuri live to report about the Flood [[YouWouldntBelieveMeIfIToldYou while likely leaving out The Doctor's involvement]].
246	* UngratefulBastard: Captain Adelaide has shades of this after tearfully begging the Doctor to intervene, break the rules of time and save her and her crew. When he gives in, returns to save her, Yuri and Mia, only then does she suddenly worry about the timeline, regret it and throw away the Doctor's efforts to save her.
247	* UnwittingInstigatorOfDoom: Both the Doctor and Adelaide. Adelaide because she prevents the Doctor from leaving immediately (thinking him a spy), and the Doctor because he doesn't know the incident in detail.
248	* TheVirus: The Flood can turn you into a zombie with just one drop.
249	* WaterSourceTampering: Exaggerated with the aliens ''in'' the water and spreading via contamination of the base's supply.
250	* WellIntentionedExtremist: The Doctor, out of a desire to save people, becomes mad with power and tries to alter the entire course of human history.
251	* WhamShot: [[LiteralMetaphor Basically:]] after dropping off Adelaide at her house, she makes it ''abundantly clear'' that she came to regret asking him to ScrewDestiny[[note]]given how it resulted in [[JumpingOffOfTheSlipperySlope him adopting the identity of the Time Lord Victorious]][[/note]], and that what he did was wrong. The Doctor doesn't care. So, they part ways, with the Doctor unlocking her front door with the Sonic Screwdriver. [[SuddenDownerEnding And no sooner does she go inside,]] [[DrivenToSuicide she pulls out her gun.]]
252	* WhatTheHellHero: The Doctor himself is called out on this by Adelaide, most prominently at the ending where she tells him that "no one should have that much power".
253	* WritersCannotDoMath: The Doctor laments Mia's young age- she'll die aged 27. However, the profiles of the crew give Roman's age as 25, even saying that he was the youngest person on Bowie Base One. Of course this is probably because [[spoiler: the Doctor manages to save Mia, but not Roman.]]
254	* TheXOfY: "The Waters of Mars".
255	* YouCantFightFate: Fixed Points are ''fixed''. You can't change them without screwing with history. Not even the last surviving Time Lord can say ScrewDestiny.
256	* YouWillBeSpared: The reason Adelaide is there at all is because a Dalek, presumably aware of her significance to history, elected [[Recap/DoctorWhoS30E12TheStolenEarth not to kill her in 2009]].
257	* ZombieInfectee:
258	** The first one gets inside the base by hiding her game face until she's in quarantine.
259	** Averted -- the second infectee immediately tells the others to leave him behind.
