The Doctor: I'm sorry. I'm so sorry
This phrase became a recurring theme in Doctor Who and its spin-offs.
*In Dalek Van Statten says it to the Dalek just before it tries to exterminates him.
*In The Doctor Dances, Nancy says it to Jamie.
*In Bad Wolf by Lynda when Crosbie is evicted from the house.
*In New Earth by The Doctor to a diseased 'New Human'.
* In The Rise of the Cybermen by Mickey Smith to his grandmother's counterpart and again by the President to the Cybermen at the party.
* In The Age of Steel by The Doctor to the dying Cyberman, Sally Phelan.
* In The Idiot's Lantern by Mr Magpie to Rose before allowing the Wire to feed on her.
* In The Impossible Planet by The Doctor after seeing Scooti's body.
* In Army of Ghosts by the Doctor as he disrupts the signals controlling Adeola, Matt and Gareth.
* And in the Torchwood episode End of Days, it is spoken by both Bilis Manger and Jack Harkness.
Lumic: Excellent. Then let's begin!
The expression 'Excellent' is a reference to the use of the word by the Cyber-Controller character (although Lumic has not yet become the Cyber-Controller at this point) in almost every previous story beginning with the Fourth Doctor episode, Revenge of the Cybermen.
At the begining of the episode as the van drives up to rescue the Doctor and the others you can see a row of Cybermen marching toward them in the background. The camera angle changes and suddenly the Cybermen are nowhere to be seen.
When The Cyberman is hit by the electro-magnetic bomb, it falls to its knees, then backwards. Yet in the next shot, it is flat on its back, with its leg extended.
Reference is made to the episode School Reunion where Mickey refers to himself as "the tin dog", a comparison to K9.
Reference is made to the episodes Dalek (Rose mentions seeing a Cyberman head in Van Statten's museum), and Parting of the Ways (Mickey mentions saving the world with a big yellow truck).
Rose: You're alive! (hugs Jackie) Oh, Mum, you're alive!
Jackie: Well, I was the last time I looked. What is it, what's happened, sweetheart? What's wrong? Where did you go?
The Doctor: Far away. That was... far away.
Jackie: Where's Mickey?
The Doctor: He's gone home.
The Doctor: (Speaking to a disabled Cyberman) Can you remember your name?
Cyberman: Sally. Sally Phelan.
Mrs. Moore: You're a woman.
Cyberman: Where's Gareth?
Mrs. Moore: Who's Gareth?
Cyberman: He can't see me. It's unlucky - the night before.
Mrs. Moore: You're getting married?
Cyberman: I'm cold. I'm so cold.
The Doctor: It's all right. You sleep now, Sally. Just go to sleep. (The Doctor uses the Sonic Screwdriver on the emotional inhibitor and the Cyberman's power dies...)
Cyber Controller: You are proud of your emotions?
The Doctor: h yes.
Cyber Controller: Then tell me, Doctor, have you known grief and rage and pain?
The Doctor: Yes. Yes, I have.
Cyber Controller: And they hurt?
The Doctor: Oh yes.
Cyber Controller: I can set you free. Would you not want that? A life without pain?
The Doctor: You might as well kill me.
Cyber Controller: Then I take that option.
The Doctor: It's not yours to take; you're a Cyber Controller, you don't control me or anything with blood in it's heart!
Cyber Controller: I will bring peace to the world. Everlasting peace. And unity. And uniformity.
The Doctor: And imagination? What about that? The one thing that led you here. Imagination? You're killing it dead.
Cyber Controller: What is your name?
The Doctor: I'm the Doctor.
Cyber Controller: A redundant title. Doctors need not exist. Cybermen never sicken.
The Doctor: But that's it! That's exactly the point! Oh, Lumic, you're a clever man. I'd call you a genius, except I'm in the room… but everything you've invented you did to fight your sickness. And that's brilliant. That is so human. But once you get rid of sickness and mortality, then what's there to strive for? Eh? The Cybermen won't advance. You'll just stop. You'll stay like this forever. A metal Earth with metal men and metal thoughts. Lacking the one thing that makes this planet so alive. People. Ordinary, stupid, brilliant people!
The Doctor: That's the key. The emotional inhibitor. If we can find the code behind it, the cancellation code, then feed it throughout the system, into every Cyberman's head, they'd realise what they are.
Mrs. Moore: And what happens then?
The Doctor: I think it would kill them. (pause) Can we do that?
Mrs. Moore: We've got to. Before they kill everyone else. There's no choice, Doctor. It's got to be done.
Mickey: You're just making this up as you go along!
The Doctor: Yep. But I do it brilliantly.
John Lumic: My everlasting children. Tell me, how does it feel?
Cyberman: We feel nothing.
John Lumic: But in your mind, what do you think?
Cyberman: We think the same. We are uniform.
John Lumic: But you think of what?
Cyberman: We think of the humans. We think of their difference and their pain. They suffer in the skin. They must be upgraded.
Mickey: The Preachers know what they're doing. Ricky said he's London's most wanted.
Ricky Smith: Yeah, that's not exactly…
Mickey: Not exactly what?
Ricky Smith: I'm London's most wanted… for parking tickets.
The Doctor: How did you get in to this, then? Rattling along with the Preachers?
Mrs. Moore: I used to be ordinary. Worked at Cybus Industries nine to five. Till one day I find something I'm not supposed to. A file on the mainframe. All I did was read it. Then suddenly I've got men with guns knocking in the middle of the night. A life on the run. Then I found the Preachers. They needed a techie so I just sat down and taught myself everything.
Mickey: I know it's not easy with my face looking exactly like Ricky. But I'm a different man. I'm not replacing him. But we can remember him by fighting in his name. (Jake nods) With all those Cyber factories out there, do you think there'd be one in Paris?
Jake Simmonds: Yeah.
Mickey: Then let's go liberate Paris.
Jake Simmonds: What, you and me? In a van?
Mickey: Nothing wrong with a van. I once saved the universe with a big yellow truck.
Peter Tyler: Who are you?
Rose: It's like you say. Imagine there are different worlds. Parallel worlds. Worlds with another Pete Tyler, Jackie Tyler still alive and their daughter.
Cyber Controller: This is the Age of Steel and I am it's creator.
The Doctor: Good luck. Mickey the idiot.
Peter Tyler: Encrypted wavelength 657 using binary 9. That's the only reason I am working for Lumic, to get information. I thought I was broadcasting to the security services, what do I get? Scooby Doo and his gang. They even got the van!
Turkey: August 15, 2010 on CNBC-e
As with Part 1, Marc Platt receives a "With thanks to" credit. Platt wrote the script for the Doctor Who audio, Spare Parts, which provided much of the inspiration for this episode.
The only significant edit made to this episode was the removal of a line confirming that Ricky and Jake had been lovers, as part of the sequence of Mickey promising not to try to take his counterpart's place.
Footage from Rose, most specifically, the destruction of the Nestene Consciousness was reused as part of the destruction of the Battersea Cyber-conversion facility.
This episode is the first time since Attack of the Cybermen that gold has not been used as a weapon against the Cybermen. The Cybus Industries tie-in site makes reference to earlier prototypes having an allergy to gold, stating that this was eliminated after further improvements of the Cyberman body.
At one point, the Doctor orders everyone to split up so that Lumic's Cyber processing centre can be broken into most effectively. He says this is so everyone can find a way in, either "above, between, below." This could be a reference to The Five Doctors because the 2nd Doctor recites a poem on how to enter the Tower Of Rassilon that uses the same phrase in it.
The final viewing figure for the BBC One airing of this episode was 7.63 million.
Mickey: What? Stay ou' o' trouble, be the tin dog? No, those days are over.
A reference to K-9 and School Reunion earlier this season, wherein Mickey realises he's the comic sidekick in the group dynamic.
Mickey: Nothing wrong wi' a van. I once saved the universe wi' a biiig yellow truck.
A reference to Mickey's use of the tow truck to gain access to the TARDIS's core at the end of the first season.
Peter Tyler: Encrypted wavelength 657.
BBC Radio Wales is broadcasting on frequency 657 kHz. Doctor Who is produced by BBC Wales.
The Doctor: Give people their minds back. So they don't walk into that place like sheep.
The marching of thousands of pod-controlled Londoners to Battersea echoes the song 'Sheep' by Pink Floyd from their album Animals, where the sheep obediently walk into a valley of steel to be butchered. The album cover features an image of Battersea Power Station, with a pig floating above it just like Lumic's zeppelin.
Incidentally Pink Floyd is known for incorporating the Doctor Who theme music into live performances of the song 'One of These Days'.
Rose: Where'd you learn to fly that thing!?!
Mickey: Playstation. Just hold on, Rose. I'm coming to get you.
The Sony Playstation is a video game console first produced by Sony Computer Entertainment in the mid-1990s, the game Mickey mostly likely used to learn to pilot a Zeppelin is X-Plane.
"I'm coming to get you", is a direct echo of the Ninth Doctor's words to Rose at the climax of 'Bad Wolf', and could be considered the final step in the transformation from Mickey the Idiot to Mickey the Hero.
Pete: I thought I was broadcasting to the Security Services, and what do I get? Scooby Doo and his gang. They've even got the van!
'Scooby-Doo, Where Are You?' premiered in 1969. The cartoon introduced four kids and a dog named Scooby-Doo. The kids were Daphne Blake, Freddy Jones, Velma Dinkley, Norville "Shaggy" Rogers. They travelled around in a green van known as "The Mystery Machine" and solved many 'scary' mysteries along the way.
Cyber-Controller: (to the Doctor) Your words are irrelevant.
This line is similar to when the Cyberleader responds to the Fifth Doctor in Earthshock Part 4 (1982), "These things are irrelevant," when the Doctor tells it how emotions have their uses.
