20	A virus lurking in deep space infects the crew of an earth shuttle on its way to Titan. The infected humans kill the crew they are supposed to be relieving, except for one man, Lowe, whom they infect. They begin preparing the base for breeding. Meanwhile, the TARDIS has been invaded by the same virus, and the Doctor [[FaceFullOfAlienWingWong becomes the host for]] the Nucleus of the Swarm. After he attempts to kill "The Reject" Leela (who is immune), the Doctor realizes what's happening and puts himself into a self-induced coma to keep from being taken over completely. Leela, accompanied by Lowe, rushes him to the Bi-Al Foundation hospital asteroid using the TARDIS, where she hopes Professor Marius will be able to find a cure.
21
22	Professor Marius, a kind old genius, immediately realizes what's been going on. While Leela goes off to fight her attackers with the help of Marius' robot dog, K-9, the (still rapidly dying) Doctor asks Marius to make temporary clones of him and Leela. Lowe infects as many of the hospital staff as possible, and the cloned Doctor and Leela are shrunk down for a FantasticVoyagePlot to try and destroy the virus by attacking it inside the Doctor's brain.
23
24	The short-lifespan clones expire before they can defeat the virus, but they drive the Nucleus out of the Doctor's brain, where it is expanded to human size. Lowe takes it back to Titan, to begin the breeding of a new giant shrimp virus super race, while Leela's decomposing clone corpse inside his brain gives the Doctor immunity to the virus. With the help of Professor Marius and K-9, the Doctor is able to isolate the immunity and synthesize a cure.
25
26	While Professor Marius treats the infected hospital staff, the travellers take the weaponized cure (and K-9) and head to Titan to finish off the virus. Leela knifes some people in the neck and keeps suggesting that the Doctor should just blow up the entire moon. He gives a grand spiel of not wanting to kill anyone, but eventually relents and ''blows up Titan''. Professor Marius returns to Earth and gives K-9 to the Doctor as a souvenir.

28	----
29	!!Tropes:
30
31	* AffablyEvil: The Nucleus holds no particular grudge against the Doctor, and admits that the Doctor would be perfectly within his rights to kill him... if he can.
32	* AsteroidThicket: The first episode begins in one, prompting one member of the relief crew to take their shuttle off auto-pilot.
33	* BigBad: The Nucleus of the Swarm.
34	* BodyHorror: A space parasite lay eggs in ''the Doctor's brain'' which begins to passively alter his behaviour, making him go vulnerable, confused and AxCrazy. [[NightmareRetardant Less scary than it sounds, unfortunately.]][[invoked]]
35	* BreakTheBadass: When a space parasite lays its eggs in the Doctor's brain and mind controls him into being evil, as soon as he realises what has happened he is so scared he's almost panicking.
36	* ChekhovsGun: The Doctor's antibodies.
37	* ClothingConcealedInjury: The station manager, Lowe, is taken over by TheVirus. As the infection manifests with a strange growth around the eyes, Lowe conceals his infection by donning a pair of blast goggles and telling people his eyes had been injured during the explosion, making him very sensitive to light.
38	* ContinuityNod: The Doctor asks Leela if she remembers [[Recap/DoctorWhoS14E6TheTalonsOfWengChiang London]].
39	* DetectEvil: Leela can "sense" the evil of the coming story so strongly that she chews on the Doctor's scarf for comfort and forcibly prevents the Doctor from opening the TARDIS doors. [[CassandraTruth Naturally]], he ignores her.
40	* DistractedByMyOwnSexy: Averted by Leela when she gets a look at her clone:
41	-->'''Leela:''' K9, [[DoIReallySoundLikeThat do I really look like that]]?
42	-->'''K9:''' "Affirmative."
43	-->'''Leela:''' ''(disapproving look)''
44	* DoubleMeaning: The Doctor and Leela make an AccidentalPun while hunting down the nucleus:
45	-->'''Doctor:''' This is the mind-brain interface, Leela. That's the mind, and that's the brain. Two things entirely different but part of the same thing.
46	-->'''Leela:''' Oh, like the land and the sea.
47	-->'''Doctor:''' That's right, that's right. ''(smiling in approval)''
48	-->'''Leela:''' It's very deep. ''(looking down into the abyss)''
49	-->'''Doctor:''' ''(unaware of this)'' Yes. Sometimes, I don't quite understand it myself.
50	* ExpendableClone: The Doctor and Leela create "quick-clones" of themselves with the full memories and consciousness of the originals. The quick-clones have lifespans measured in hours, and the Doctor isn't terribly bothered about it.
51	* FaceFullOfAlienWingWong: An alien parasite that transmits itself via electrical impulses and light implanted its eggs in the Doctor's brain via his eyes. The larva hatched and escaped through the Doctor's tear ducts, but the Doctor forced it to grow to human size using his TARDIS's dimensional stabiliser and killed it.
52	* FantasticVoyagePlot: At one point, the Fourth Doctor has himself and Leela cloned and shrunk down so he can be injected into his own brain, and fight the monster that's nesting inside it.
53	* FightingFromTheInside: The Doctor tries to resist the virus and succeeds in slowing it.
54	* {{Foreshadowing}}: At the very beginning of the first episode, the Doctor compares humanity's explosion into the galaxy to a virus.
55	* GeneticMemory: The clones of the Doctor and Leela have the memories of their originals. K9 explains that this is because they are more like "biological photocopies" than proper clones, hence their shortened lifespans. Which does not in any satisfactory way explain how they cloned their ''clothes''. Homaged much later on in [[Recap/DoctorWhoS30E6TheDoctorsDaughter "The Doctor's Daughter"]].
56	* GenreShift: Coming after "[[Recap/DoctorWhoS15E1HorrorOfFangRock Horror of Fang Rock]]" which had retained much of the GothicHorror vibes from Creator/PhilipHinchcliffe's run, this serial is arguably the point where the DenserAndWackier Creator/GrahamWilliams era begins in earnest.
57	* GladIThoughtOfIt: Blowing up the Nucleus and its eggs:
58	-->'''The Doctor:''' Good idea of mine, K-9, to blow them up.
59	-->'''Leela:''' But it was my idea!
60	-->'''The Doctor:''' Then you should be feeling very happy right now.
61	* HerrDoktor: Professor Marius.
62	* HypnoticEyes: ''Contact has been made.''
63	* ImpaledWithExtremePrejudice: Leela believes she has figured out the perfect way to stop the Nucleus' thralls.
64	-->'''Leela''': Knife them in the neck!
65	* InformedSelfDiagnosis: An odd inversion in that the Doctor's self diagnosis confirms Professor Marius's analysis, rather than the other way around.
66	* InhumanEyeConcealers: The station manager, Lowe, is taken over by TheVirus. As the infection manifests with a strange growth around the eyes, Lowe conceals his infection by donning a pair of blast goggles and telling people his eyes had been injured during the explosion, making him very sensitive to light.
67	* LighterAndSofter: Following the Creator/PhilipHinchcliffe-era holdover that was [[Recap/DoctorWhoS15E1HorrorOfFangRock "Horror of Fang Rock"]], this story marked the start of the Creator/GrahamWilliams era's shift to a lighter, less grim direction (per BBC mandate). While the idea of the Doctor combatting a deadly virus slowly infecting the crew wouldn't sound out of place with earlier seasons, the execution leans into a more overtly child-friendly direction, most prominently introducing KidAppealCharacter K9, who would quickly be promoted from a one-off character to a companion.
68	* MalevolentMaskedMen: The infected shuttle crew have their space helmets when going to kill those on the base. On lifting the visors, we see how the Virus has altered them.
69	* MegaMicrobes: The miniaturized clones of Leela and the Doctor confront the virus inside the real Doctor's brain. Later, the virus is taken out of the Doctor and enlarged to human scale.
70	* [[NotHimself Not Themselves]]: The Titan relief crew initially, then the Doctor. Leela can tell the difference instinctively.
71	* NuSpeling: Used for signage throughout. An exit sign on Titan is clearly marked "Imurjinsee Egsit", the entrance lobby of the hospital has a doorway designated "Shutle Airlok", the hospital ward where the Doctor is treated is labelled "Isolayshun", and so on.
72	* OurMonstersAreWeird: The Swarm is a sentient brain parasite that transmits itself across space through a flashing pulse of light. Witnessing this light pattern causes the Swarm to be created in your brain.
73	* ParrotExpoWhat: When the Doctor tries to explain things, Leela keeps repeating words she doesn't understand. Including 'parrot?'.
74	* PigLatin: Professor Marius gives K-9 the order to 'kanayli' the infected.
75	* PuppeteerParasite: The Nucleus and its ilk.
76	* PushyGunTotingVillain: Lowe (under control of the Nucleus) becomes this when he attempts to force the Doctor at blaster-point into the Nucleus breeding chambers as food.
77	* RobotBuddy: K-9.
78	* RunningGag: As in "[[Recap/DoctorWhoS14E2TheHandOfFear The Hand of Fear]]", Gallifrey is mistakenly believed to be in UsefulNotes/{{Ireland}}.
79	* SeekerWhiteBloodCells: While inside the Doctor's body[[note]]Yes, the Doctor travels inside his own body. ItMakesSenseInContext.[[/note]], the Doctor and Leela are attacked by white blood cells, but the Doctor uses a nearby nerve cluster to send them a fake message summoning them to a different part of the body. Now, this wouldn't work in a human body, where white blood cells just wander aimlessly and deal with whatever they happen to come across, but maybe a Time Lord's immune system [[BizarreAlienBiology works differently]].
80	* ShrinkRay: The Doctor and Leela are shrunk with a shrink ray based on the same technology as lets the TARDIS be bigger on the inside, allowing a bit of handwaving about the issues of shrinking living things.
81	* SomeOfMyBestFriendsAreX: The Doctor, just before he adds that in large groups HumansAreBastards.
82	* {{Spoonerism}}: Despite the audience already knowing the malevolence of the Nucleus from the previous and presently-developing scenes, after the Doctor wakes from the Nucleus' contact, this is the first sign that something is ''very'' wrong with him.
83	--> '''Fourth Doctor:''' Hello, Lalee.\
84	'''Leela:''' Are you all right?\
85	'''Doctor:''' Rightly perfect. Thank you, yet, Lalee.\
86	'''Leela:''' What did you say?\
87	'''Doctor:''' I said "I'm perfectly all right, thank you, Lalee."\
88	'''Leela:''' My name is ''Leela''.\
89	[...]\
90	'''Doctor:''' Must have had a bot of a shick.\
91	'''Leela:''' What?\
92	'''Doctor:''' A bot of a shick. ''[He shakes his head and blinks, as if having trouble concentrating]''
93	* TechnoBabble: More like medi-babble, but still.
94	* TheVirus: The Nucleus.
95	* VisibleBoomMic: When the Doctor is congratulating himself on blowing up the Swarm, the shadow of a boom mike can be seen.
96	* WholePlotReference: To ''Film/FantasticVoyage''.
97	* WigDressAccent: Leela disguises herself as an infectee with remarkably sophisticated face paint to gain access to the Doctor.
