Martha: Jack's right. These attacks are not random. They're clinical, professional. More like assassinations.
Gwen: Except Barry Leonard was a student. Who'd assassinate a student?
Martha: Student loans company?
Gwen: Yeah, I think you just cracked it.
[They both laugh.]

Martha: So, Jack asked me if I could get you a UNIT cap to wear.
Ianto: Did he? Well, red is my colour.
Martha: So, am I right in thinking that you and he...
Ianto: We... dabble.
Martha: Yeah?
Ianto: Yeah.
Martha: So what's his "dabbling" like?
Ianto: Innovative.
Martha: Really!
Ianto: Bordering on the avant-garde.
Martha: Wow.
Ianto: Oh yeah. [He smiles a little distantly]

Martha: There is no sign of any muscle decay. You're in great shape, as ever.
Owen: No use coming onto me, Jones. I'm a changed man.
Martha: And no stiffening anywhere?
Owen: Well...
Martha: Just answer the question

Newscaster: Under the Emergency Miracle Law, anybody designated as category one or category two must be taken to the new overflow camps. The scheme is already underway in the United Kingdom with the Prime Minister calling this a new age of care and compassion.

Oswald: How much do you know about our masters at Phicorp? Because I did a little searching of my own last night. It's been a long long time since I was allowed online, so...I tried to find out who's above Phicorp. Who owns them. But the strangest thing happened. The information just scattered away. All sorts of names and tangents and diversions, but nothing tangible. And that's when I recognized the pattern. Because I've had a lot of experience perfecting how to hide myself online. And suddenly, I'm looking at someone else doing the same. But on a massive scale. Worldwide. I wonder why.

Oswald: I felt her life leave, and she left through me. You know that feeling. I think you do. And I relive it, every single night, because that was the best moment of my life.
Jack: Now I understand. You're doing all this because you're searching for one thing. One simple thing. Execution. We're without death, so you get to live. And it's killing you.

Oswald: I'm asking you now to join with me, in this enterprise, as we all walk across the fragile skin of this wide world together. The future is now endless. And it's terrifying, I'm offering you my hand to walk on this long journey. Together. Walk with me. That's all I ask. Walk with me.

Oswald: Jack Harkness. I could accuse you of having an obsession with me.
Jack: What happens after this, Oswald? When the fever dies down and the world wakes up to the fact that a murderer's standing center stage? Somewhere out there those men are waiting for you in the dark.

Oswald: The truth is I know what I am. I know what you are too. Yes, I do. Each and every one of you. Because I know for certain what has happened to the human race. I know, because this has happened before. Fifty thousand years BC. What's called the great leap forward. Human beings suddenly, we started to bury our dead. We created art and money. And love. They loved. They learned to love. We made a leap from animal to human. ANd now, right now, in our very own lifetimes it has happened again. The next great leap. We have made it from animal to human to what? This is the question. After Miracle Day, what are we now? I know. This is something I know. Because I am the man who has lost Heaven forever. So I can feel the truth of it. I'm telling you, man has risen again! Now, he has a new name. And his name is Angel. Angel. Angel. We are angels. We have been helped. We have been purified. We have been given life unending. We are the first angels on Earth. And I promise you this, there are even those who have been planning for this. The agents of angels in this brand new world. I'm telling you right now, they stand amongst us. Yes! For this is my revelation!

Oswald: There are people out there who are preaching all sorts of dangerous lies about you. And who is out there talking on your behalf? Hmm? I'm here to tell you, I will. I promise, I will. Because you need help.

Oswald: Who are you?
Jack: Captain Jack Harkness.
Oswald: No. I spent a long time in prison. And I know the smile of a man who's done terrible things. And your friends. I've been watching them. Sometime they like you, sometimes they love you... and sometimes once or twice, fluttering away in those tiny little gaps, they fear you.
Jack: I'm from the future.
Oswald: Well, now.
Jack: I come from the future.
Oswald: Then you must know. Do we make it through this day?
Jack: The future can change. It's being written right now. One thing I do know. I've seen the stars. I have seen the universe. I have seen the human race become vast and magnificent and endless. And I wish you could see it, Oswald. I wish you could see that, too. Because then you'd know how small you've made your life.

Owen: [re: the life knife] Ianto?
Ianto: [deadpan] Life knife.

Owen: [re: the Resurrection Gauntlet.] You know, we never gave it a cool name.
Tosh: I thought we just called it "the Resurrection Gauntlet".
Owen: Cool name.
Ianto: What about... the Risen Mitten?
[Jack raises his eyebrows and Owen rolls his eyes despairingly.]
Ianto: I think it's catchy.

Owen: [supposedly telling Martha what death is like] There was a light, a tiny speck of light and I was rushing towards it, like down a corridor, and it got brighter, and brighter, then suddenly there were these gates... these big, pearly gates and there was this old geezer and he said, "You've been a very naughty boy!"

Owen: [talking to a child cancer patient] Jamie, you're scared, of course you are, the last lot of chemo didn't work and you can't bear the thought of going through all that pain again, I understand that mate, I really do. But let me tell you, that not everyone dies from this disease. And the ones with the best chance of making it are the ones who believe they can beat death. And sometimes, just sometimes, you can. So watch and learn, Jamie Burton.
Jamie: Watch what?
Owen: Watch me beat Death.
Tosh: [finally picking the lock on a door] Come on!
Owen: Okay, go, come on, Jamie, [to Tosh] take him!
Tosh: Owen? I am not leaving you to face that thing on your own!
Owen: I know what to do.
Tosh: We don't know what we're dealing with!
Owen: Tosh... [kisses Tosh] you're so going to hate me for this. [uses the lock-picking device to shut himself in the lobby]
Tosh: Owen, no, open the door! What the hell are you doing? Owen!
Owen: [to Death] How long!? How long can you last here with only twelve victims? There's nothing here for you! Owen Harper's soul has left the building! There's nobody here but us dead men. [starts fighting Death to the protestations of his team] What else have you got? What else do you do to the dead? Is that all you've got? Is it?!? [Death eventually fades away in a white light]
