You're a fine doctor, Clipton, but you've a lot to learn about the army.Colonel Nicholson
I'm adamant. I will not have an officer from my battalion working as a coolie.Colonel Nicholson
Ripley: Will you listen to me, Parker? Shut up!
Parker: Let's hear it. Let's hear it.
Ripley: It's using the air shafts.
Parker: You don't know that.
Ripley: That's the only way. We'll move in pairs. We'll go step by step and cut off every bulkhead and every vent until we have it cornered. And then we'll blow it the fuck out into space! Is that acceptable to you?
I realize how difficult it's going to be in this god-forsaken place where you can't find what you need, but there's the challenge.Colonel Nicholson
Ripley: Did you ever ship out with Ash before?
Dallas: I went out five times with another science officer. They replaced him two days before we left Thedus with Ash. Hmm?
Ripley: I don't trust him.
Dallas: Well, I don't trust anybody.
We can teach these barbarians a lesson in Western methods and efficiency that will put them to shame. We'll show them what the British soldier is capable of doing.Colonel Nicholson
Micro changes in air density, my ass.Ripley
Nurse at Ceylon hospital: What makes you so sure you'll get a medical discharge?
Commander Shears: Because I'm a civilian at heart, lover, and I always follow my heart.
Ripley: That's amazing. What is it?
Ash: Uh, yes, it is. Umm. I don't know yet. Did you want something?
Ripley: Yes, I, uh... have a little talk. How's, uh, how's Kane?
Ash: He's holding, no changes.
Ripley: And, uh, our guest?
Ash: Well, as I said, I'm still... collating, actually, but uh, I have confirmed that he's got an outer layer of protein polysaccharides. Has a funny habit of shedding his cells and replacing them with polarized silicon, which gives him a prolonged resistance to adverse environmental conditions. Is that enough?
Ripley: That's plenty. What does it mean?
[Ripley bends down to look through the micro-scanner]
Ash: Please don't do that. Thank you.
Ripley: I'm sorry.
Ash: Well, it's an interesting combination of elements making him a... tough little son-of-a-bitch.
Ripley: And you let him in.
Ash: I was obeying a direct order. Remember?
Ripley: Ash. When Dallas and Kane are off the ship, I'm Senior Officer.
Ash: Oh, yes, I forgot.
Ripley: You also forgot the Science Division's basic quarantine law.
Ash: No, that I didn't forget.
Ripley: Oh, I see, you just broke it. Hmm?
Ash: Look, what would you have done with Kane, hmm? You know his only chance of survival was to get him in here.
Ripley: Unfortunately, by, uh, breaking quarantine, you risk everybody's life.
Ash: Maybe I should have left him outside. Maybe I've jeopardized the rest of us, but it was a risk I was willing to take.
Ripley: That's a pretty big risk for a Science Officer. It's, uh, not exactly out of the manual, is it?
Ash: I do take my responsibilities as seriously as you, you know. You do your job and let me do mine, yes?
Ripley: Ash, that transmission... Mother's deciphered part of it. It doesn't look like an S.O.S.
Ash: What is it, then?
Ripley: Well, I... it looks like a warning. I'm gonna go out after them.
Ash: What's the point? I mean by the, the time it takes to get there, you'll... they'll know if it's a warning or not, yes?
I tell you, gentlemen, we have a problem on our hands.Colonel Nicholson
Good show! Jolly good show, Major!Colonel Green
