[After finding Owen in the cell naked]
Jack, Carys is out of her cell!
Cheeky bitch took my swipe card.
Jack
I'll deal with it. Tell Owen he needs to work on those abs a bit harder.
I was taking some readings, you know, keeping an eye on her, and bang!
You got away lightly. Be thankful she was only interested your swipe card.
Are you alright now, or are you still feeling a bit of a cock?
What? I have to do that again?!
Jack
Someone does! Any volunteers? [throws the ghost device at Owen]
We don't know what it is, what it does.
Jack
Nope.
Jack, this could be dangerous.
Jack
Yeah.
Uh, I don't mean to be picky, but I think I can spot some flaws in this plan...
Jack
I'm sorry! I thought you were the guys who gave up looking for a nineteen year old kid this morning! I figured maybe you were up for something more exciting!
I'm going back in to save her. Anybody tries to stop me, I'll shoot them.
Jack
You make a threat like that, you better be prepared to follow it through. See? You disobey me now, I really will shoot you.
Jack
You want to go back in there? You go in to finish the job. If she's still alive, you execute her.
Jack
You brought this down on us. You hid her. You hid yourself from us. Now it's time for you to stand as part of the team.
Jack
The girl you loved has gone. Your loyalty is to us now.
You can't order me to do that.
Jack
You execute her, or I'll execute you both!
I won't do it. You can't make me. You like to think you're a hero, but you're the biggest monster of all.
Jack
[pointing his gun at Ianto] Did you know that thing was down there?
Jack
[enraged] You hid a Cyberman within Torchwood?! And you didn't tell us?! What else are you keeping from us?!
[scathingly] Like you care. I clear up your shit, no questions asked, and that's the way you like it. When did you last ask me anything about my life? [pause] Her name's Lisa. She's my girlfriend.
Why didn't you tell us? We could have helped you.
Torchwood exists to destroy alien threats. Why would I tell you about her?
[angry] A little loyalty, perhaps?
My loyalty's to her. She worked for Torchwood. She was caught up in the battle. I owe it to Lisa, we owe it to her, to find a cure.
Jack
Ianto, you have to believe me, there is no cure. There never will be. Those who are converted stay that way. Your girlfriend will not be the exception.
You can't know that for sure!
Jack
Look, you need to know what's happening here. Because this is where these things start, small decisions that become mass slaughter. These creatures regain a foothold by exploiting human weakness. Then they take a base, rebuild their forces, and before you know it, the Cyber race is spreading out across the universe, erasing worlds, assimilating populations, all because of the tiny beginnings here. We need to stop her together!
You're not listening to me. The conversion was never completed.
Jack
She already tried to kill Gwen. You think she's gonna stop there? There is no turning back for her now.
I'm not giving up on her. I love her. Can you understand that, Jack? Haven't you ever loved anyone?
Jack
...You need to figure out whose side you're on here, because if you don't know, you're not going to make it out of this alive.
[talking about his former love, Estelle's, visions of fairies]
Jack
She calls them fairies; I don't.
Jack
Never really had a proper name.
Jack
Something from the dawn of time, how could you possibly put a name to that?
Jack
Worse.
Jack
Because they're part of us. Part of our world, yet we know nothing about them. So we pretend to know what they look like. We see them as happy, we imagine they have tiny little wings and are bathed in moonlight.
Jack
No. Think dangerous. Think something you can only half-see, like a glimpse, like something out of the corner of your eye. With a touch of myth, a touch of the spirit world, a touch of reality all jumbled together, old moments and memories that are frozen in amongst it. Like debris, spinning around a ring planet, tossing, turning, whirling... backwards and forwards through time.
[after the fairies kill Estelle]
It wasn't your dad that was in love with her all those years ago, was it? It was you.
Jack
We once made a vow... that we'd be with each other till we died.
Jack
you need to know something. A long time ago, I was pretty good at torture. I had quite a reputation as the go-to guy. My job demanded, at the time, see. So I know where to apply the tiniest amount of pressure to a wound like yours...
CCannibal
stop, you're going to kill me!
Jack
it's in your power to make me stop. Just tell me what I need to know! 'Cause in ten seconds, I'm going to find a sharp object.
