Purvis: [shouting] What's in-fucking-side me?
Dr. Wren: A parasite! A foreign element.
Ripley: There's a monster in your chest. These guys hijacked your ship, and they sold your cryo tube to this... human. And he put an alien inside of you. It's a really nasty one. And in a few hours it's gonna burst through your ribcage, and you're gonna die. Any questions?
Purvis: Who are you?
Ripley: [smiles] I'm the monster's mother.
Johner: Don't push me, little Call. You hang with us for a while, you'll find out I am not the man with whom to fuck!
Ripley: [voiceover] My mommy always said there were no monsters. No real ones. But there are.
Call: Father's dead, asshole. Intruder on level one. All aliens, please proceed to level one.
Johner: Earth, man. What a shithole.
Elgyn: She is severely fuckable, ain't she?
General Perez: Ellen Ripley died trying to wipe this species out. For all intents and purposes, she succeeded!
[when the Alien "baby" emerges from the Queen's womb]
Dr. Gediman: You are... a beautiful, beautiful, butterfly.
Vriess: [Strapped to Christie's back, about to traverse the flooded kitchen] Hey Christie, do me a favour. When we hit the surface on the other side, no backstroke, okay!
Johner: I'm not the mechanic here, Ironsides! I mostly just hurt people!
[the Newborn Alien slowly dies by being sucked out of the Betty and into space]
Ripley: [tearfully] I'm sorry.
Dr. Wren: Then this little synthetic bitch is gonna plug into the Auriga, and she is gonna take us right back to home base, according to the standard emergency procedures.
Call: No, she's not!
Distephano: Are you crazy? You still wanna bring those things back to Earth?
Johner: Haven't you been payin' attention today?
Dr. Wren: Ah, the intellectual speaks.
Call: You're a thing, a construct. They grew you in a fucking lab.
Call: He is breeding an alien species. More than dangerous. If those things get loose, it's gonna make the Lacerta Plague look like a fucking square dance!
Elgyn: Hey, son, I'll give ya my authorization code. It's E-A, T-M, E.
Johner: [to Call] Kill you! Does that compute?
Dr. Gediman: [after watching the massacre in the mess hall] Security! There is a serious problem in the mess hall!
Johner: I thought synthetics were supposed to be all logical and shit. You're just a big ol' psycho girl!
Johner: [to Ripley] If you don't want to play basketball, I know some other indoor sports.
Ripley: [to Call] Are you gonna kill me or what?
Ripley: You did it. You saved the Earth.
