The Doctor: No, it is not a game.
Jamie: Of course it isn't, Doctor. People have died. The Daleks are all over the place, fit to murder the lot of us, and all you can say is that you've had a good night's work!
The Doctor: Jamie...
Jamie: No, Doctor! Look, I'm telling you this, you and me, we're finished. You're just too callous for me. Anything goes by the board, anything at all.
Jamie: I don't know. Did you? Look Doctor, just whose side are you on?
The one where the Daleks say goodbye... for now.
At the end of the previous story, the TARDIS was nowhere to be found - turns out it's been stolen by Edward Waterfield, a Victorian antique dealer who has been sent forward in time by the Daleks to capture the Doctor and Jamie.
The Daleks are trying to understand the "Human Factor" - the special quality humans possess that has enabled them to defeat the Daleks so often. Jamie is forced to complete a test - the rescue of Waterfield's daughter Victoria - while being monitored by the Doctor. With the "Human Factor" isolated, the Doctor implants it into three Daleks, who become amiable and playful.
Everyone is suddenly whisked off to Skaro where it turns out that actually the Daleks are trying to isolate the "Dalek Factor" - the impulse to kill and destroy - and implant it into humans, with the TARDIS being used to spread this throughout time and space. The Doctor implants more Daleks with the Human Factor and a civil war breaks out as the Doctor, Jamie and Victoria escape. With her father dead, Victoria comes along aboard the TARDIS as the Doctor watches the destruction of the Dalek city and muses that this must surely be their final end. Yeah, about that...
Note that this is probably the only time the show really meant it when they said the Daleks were destroyed; this was intended to be the final Dalek story ever in Doctor Who, as their creator was busy trying to sell a Dalek series to America. It didn't take, but it was still five years before they returned to the show. Thus this is probably the closest we'll ever get to a "last Dalek story."
- Always Chaotic Evil: The first time the series averts this trope with the Daleks by having a few of them show compassion, though only because their biology was altered. The revival series ran with the idea; Dalek Sec, Dalek Caan and Rusty would follow.
- Artistic License Economics: Maxtible shares the alchemists' dream of transmutating metal to gold. Never mind that having more gold around would actually devalue the stuff.
- Asshole Victim: Kennedy. Maxtible as well.
- Author Appeal: David Whitaker liked any excuse to write about alchemy and here is the culmination of his obsession.
- Batman Gambit: The Doctor pulls one on Jamie, knowing that Jamie would "infect" the Daleks with all that was good noble in humanity. Jamie doesn't take it well.
- Beard of Evil: Maxtible. A big, bushy one at that.
- Big Bad: The Dalek Emperor.
- Bottle Episode: Episode 4 is Doctor-lite and (one) companion-lite as Patrick Troughton was on holiday. It mostly is about Jamie running down corridors with Kemel, with the Doctor only appearing in a pre-recorded sequence where he describes Jamie's personality to the Dalek, and Victoria, only appearing in a quick pre-recorded shot right at the end.
- Brief Accent Imitation: The Doctor briefly speaks like a Dalek in order to convince them he's been Dalekised.
- Canon Immigrant: The Dalek Emperor first appeared in Dalek comics and annuals, though he looked considerably different here.
- Civil War: The Doctor orchestrates one between the "Human Factor" Daleks that he created, and the normal Daleks led by the Emperor.
- Compelling Voice: Arthur Terrall hears a Dalek constantly telling him "OBEY!"
- Corrupt Corporate Executive: Maxtible is the Victorian version of this trope.
- Deal with the Devil: Maxtible is helping the Daleks in the hope of getting the secret of turning base metal to gold. His eventual reward is to be turned into a human Dalek.
- Death by Origin Story: Victoria's father is killed by the Daleks, while her mother is already dead.
- Defeat Means Friendship: Jamie and Kemel.
- The Dulcinea Effect: The Daleks' plan relies on Jamie being prepared to risk his life to save Victoria, whom he hasn't even met at that point. He does just that.
- Dumb Muscle: Defied. It's Maxtible's opinion of Kemal, largely due to his mutism, but we see through his work with Jamie that he's actually rather clever.
- Early Installment Weirdness: The Daleks want to test Jamie because he is special among humans as a result of having travelled in time, but when the Doctor asks why the Daleks don't just test him, they inform him that he has travelled in time too much and is consequently "more than human," which seems to imply that the Doctor was somehow changed or mutated by his excessive exposure to time (an idea that would resurface much later on).
- Enemy Civil War: Alpha, Beta and Omega are given human emotions, which turns them friendly, and sparks off a civil war which (supposedly) destroys off every Dalek.
- The End... Or Is It?: Something that's often forgotten about the ending (thanks in part to the episode in question having been wiped from the archives); after the Doctor has solemnly proclaimed these events to be the Daleks' final end, the camera pans across the ruins of Skaro until it comes across a seemingly destroyed Dalek... that begins to move. That said, the Dalek in question is a white Dalek, and since only white Daleks have been implanted with the human factor, it could also imply that the entire remaining species did a HeelFace Turn... not that it matters anyway, since they are back to their villainous ways the next time we see them anyway (this could be explained by the story that appeared in Doctor Who Magazine that is mentioned under Heroic Sacrifice below).
- Evil Sounds Deep: The Emperor Dalek speaks with a deeper and more booming voice than its subjects.
- Fire-Forged Friends: Jamie and Kemel as they try to rescue Victoria from the Daleks.
- Flat "What": The Doctor has just boasted that he's beaten the Daleks, only to be deflated by what the Emperor tells him.The Emperor: Silence! The Human Factor showed us what the Dalek Factor was.
The Doctor: What?
- Flowers of Romance: Subverted in a heartbreaking way with Victoria, whom Jamie was deeply attracted to, giving a flower, not to him, but to Kemel, who later shows it to Jamie.
- For the Evulz: The Daleks. Pointed out by the Doctor:"Everything you say, Waterfield, is true. If we cannot find Jamie, the Daleks will take pleasure in killing everyone in sight, and their greatest pleasure will be in killing me."
- Gambit Pileup: The Doctor uses a reverse-psychology Batman Gambit to get Jamie to play into the Daleks' plan, which is to observe him pulling a daring rescue so that they can isolate the "Human Factor" and use it to make themselves unbeatable. The Doctor himself is playing along, presumably because he can predict that it will make them friendly. Only, the Daleks are themselves playing a Batman Gambit: They're not actually interested in the "Human Factor" at all—they want to use that to isolate the "Dalek Factor" to implant into humans.
- Gratuitous Greek: The first three Renegade Daleks with the Human Factor are named Alpha, Beta, and Omega.
- HeelFace Turn:
- Kemel sides with Jamie after Jamie saves him from falling to his death. Though to be fair, Kemel was never actually a genuine villain. He was lied to by Maxtible, and once he learned the truth he quickly made things right.
- The good Daleks after the Doctor implants the Human Factor into them.
- Heroic Sacrifice:
- Edward Waterfield pushes the Doctor out of the way of a Dalek blast, and is killed instead.
- The good Daleks all die fighting the Emperor and his loyal Daleks. A story in Doctor Who Magazine showed some had actually survived and created a civilisation in the oceans of another planet; however, they perform a Heroic Sacrifice to defeat a monster.
- Humanity Is Infectious: The human factor makes Alpha, Beta and Omega less Dalek-like.
- Humans Are Special: This belief led to Alpha, Beta and Omega's creation in the first place. It seems the belief was not unfounded.
- Imposter Forgot One Detail: When creating the good Daleks, the Doctor writes lowercase Greek letters onto their casings. When he sees a Dalek with an uppercase Omega approaching, he's quick to realise it's a trap.
- It's All About Me: When Edward Waterfield wants to know about Victoria's well-being, Maxtible tells him, "I am not a nursemaid to your daughter!" The only thing he cares about is the Daleks' promise to give him the secret of turning "base metal into gold!".
- Killed Off for Real: This was originally intended for the Daleks, but their immense popularity eventually made a comeback inevitable. They've developed a very bad case of Joker Immunity since then.
- Madness Mantra: killkillkillkillkillkillkillkillKILLKILLKILLKILLKILLKILLKILLKILL
- Mad Scientist: Although he's not really much of scientist at all, Maxtible fits the trope, and he gets madder as the serial progresses.
- Mad Scientist's Beautiful Daughter: Maxtible and Waterfield both have beautiful daughters (Ruth and Victoria, respectively) who are unaware of their true activities.
- Mind-Control Device: The Daleks use one on Arthur Terrall on Earth. When the story moves to Skaro, the Doctor and the Daleks both try to use the same machine on each other.
- Missing Mom: We only see a portrait of Victoria's mother, though she did appear in the original script.
- Off-the-Shelf FX: Louis Marx toy Daleks were used in the filming of the final Dalek civil war sequences (some raw film for which survives).
- One Steve Limit: The Dalek Omega is not to be confused with the Time Lord of the same name.
- Oh, Crap!: The Doctor has one of these moments when Maxtible mentions using static electricity in the experiments.
Doctor: What are they called, these creatures?Dalek: Doctor! Now do you understand?Doctor: (terrified): Oh, yes. Perfectly.
- The Doctor gets another one when he finds out who's responsible for all this.
- Punctuated! For! Emphasis!: "DO! NOT! FIGHT! IN! HEEERE!"
- Railing Kill : How Jamie and Kemel dispose of one of the Daleks.
- Recycled Soundtrack: Sound effects from "The Daleks" and "The Daleks' Master Plan" are reused for the Dalek city.
- Smug Snake: Maxtible.
- Spoiler Title: As with most Dalek-based serials from Classic Who, the first episode ends with the dramatic reveal of a Dalek!
- Stuff Blowing Up: In the surviving footage of episode 7, there is an explosion every few seconds. Shortly before the clip cuts out, a Dalek goes bang.
- Sword Fight: Jamie has one with Arthur Terrall. Sadly, it's in a lost episode, so we can only imagine how awesome it was.
- Theme Naming: Alpha, Beta and Omega are all named after letters in the Greek alphabet.
- The Voiceless: Kemel.
- Voice of the Legion: The Emperor Dalek.
- What the Hell, Hero?: Jamie towards the Doctor, twice. See quote at the top.
- The X of Y: The second Dalek story, and the second story overall, to use this format for its title.
