The Doctor: Oh, you've redecorated. I don't like it.
Craig Owens: It's a different house. We moved.
The Doctor: Yes, that's it.
Craig Owens: Doctor, what are you doing here?
The Doctor: Social call. Thought about time I'd try one out.

Craig Owens: I can't cope on my own with him. I can't... he just cries all the time. I mean, do they have off switches?
The Doctor: Human beings. No, I've checked.
Craig Owens: No, babies.
The Doctor: Same difference.

The Doctor: So what did you call him? Will I blush?
Craig Owens: No, we didn't call him "The Doctor."
The Doctor: No, I didn't think you would.
Craig Owens: He's called Alfie. What are you doing here, anyway?
The Doctor: Yes, he doesn't like Alfie. Personally he prefers to be called "Stormageddon, Dark Lord of All."
Craig Owens: Sorry, what?
The Doctor: That's what he calls himself.
Craig Owens: And how'd you know that?
The Doctor: I speak Baby.
Craig Owens: Of course you do.

The Doctor: Craig!
Craig Owens: What the hell are you doing here?
The Doctor: Oh, I'm the Doctor, I work in a shop now. Here to help. Look, they gave me a badge with my name on, in case I forget who I am. Very thoughtful, as that does happen.

The Doctor: You look awful.
Craig Owens: (about his baby son) I haven't slept, have I? I still can't stop him crying. I even tried singing to him last night.
The Doctor: Yeah, he did mention that... he thought you were crying, too.

The Doctor: Craig, take Alfie and go home.
Craig Owens: No.
The Doctor: No?
Craig Owens: No. I remember from last time, people got killed. People that didn't know you. I know where it's safest for me and Alfie, and that's right next to you.
The Doctor: Is that so?
Craig Owens: Yeah, you always win, you always survive.
The Doctor: Those were the days.

Craig Owens: Where am I investigating?
The Doctor: Well, look around. Ask questions. People like it when you're with a baby. Babies are sweet. People talk to you. That's why I usually take a human with me.
Craig Owens: So I'm your baby?
The Doctor: You're my baby.

Craig Owens: Doctor, listen to me. If the Cybermen are here, then we're not safe. We've got to go. We got to go back to base.
The Doctor: We've got a base? When did we get a base?

Craig Owens: I'm going down to the shop. We're out of milk. You know what to do if he cries.
The Doctor: No!
Craig Owens: Me neither!

The Doctor: (to the baby) Your dad's trying his best, you know. Yes, I know it's not his fault he doesn't have mammary glands. No, neither do I.

Craig Owens: The Cybermen. They blew up. I blew 'em up with love!
The Doctor: No, that's impossible. And also grossly sentimental and over-simplistic. You destroyed them because of the deeply-ingrained hereditary human trait to protect one's own genes, which in turn triggered a... uh... uh... yeah. Love.

Craig: Like a--like a "beam me up" teleport like you see in Star Trek.

In the various Star Trek TV series, a "transporter" is employed to teleport, or "beam" characters to and from the ship, and avoid the expense of having to do shuttlecraft model and CGI effects.

The Cybermats, which first appeared in "The Tomb of the Cybermen" (1967) and were last seen in "Revenge of the Cybermen" (1975), make their first appearance in the new series.
