Jack: The Torchwood Institute was set up by the British Royal Family in 1879 to defend the realm of Great Britain by investigating the unusual, the strange. And the alien.
Esther: I'm kind of guessing alien doesn't mean foreign.
Jack: Alien. As in extraterrestrial.

Jack: Water? I'm American, too! Can't I contribute to our global cultural hegemony with a nice frosty cola?!

Jack: We did it. We're whistle blowers. Every major news organization. The world knows the truth now. Let the outrage begin.
Rex: You really think it's that easy, hmm?

Jilly: Dr. Juarez!
Dr. Juarez: This is disgusting.
Jilly: [thrilled] I know!

Jilly: There's a good reason the churches are empty. People don't want to hear about Heaven. They'd rather hear from the man who has gazed into Hell itself, and that's you. Frankly I think if the Devil himself were to walk this earth, he'd need representation.
Danes: If the Devil himself walked this earth, he'd surely be working in PR.

Jim: It's the story of Tithonus. One of the Greek goddesses asks Zeus to make Tithonus immortal, but she forgot to ask for eternal youth. He became so ancient and decrepit that he eventually shrank into a cicada. He begged for death.
This is no miracle. This just, this just means that sooner or later we're all going to hell.

Lenses: We have your mother. We have your husband. We have your child.
Gwen: Who are you? What do you want? What do you want?!
Lenses: Bring us Jack.

Maitre'd: Love the vintage coat.
Jack: Thanks. Maybe the three of us should have dinner sometime.

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.
