All these science spheres are made of asbestos by the way, keeps out the rats. Let us know if you feel a shortness of breathe, a persistent dry cough or your heart stopping, because that's not part of the test. That's asbestos.

Did you feel that? That idiot doesn't know what he's doing up there. This whole place is going to explode in a few hours if somebody doesn't disconnect him. I can't move, and unless you're planning to saw your own head off and wedge it into my old body, you're going to need me to replace him. We're at an impasse.

If the rules of physics no longer apply in the future, then god help you.

Announcer: Good Morning! You have been in suspension for nine, nine, nine, nine, nine nine...
Wheatley: Hello?
Announcer: This courtesy call is to inform all test subjects to vacate the Enrichment Center.
Wheatley: Are you going to open this door? Because it's fairly urgent.

GLaDOS: Oh, thank God you're all right. You know, being Caroline taught me a valuable lesson. I thought you were my greatest enemy, when all along you were my best friend. The surge of emotion that shot through me when I saved your life taught me an even more valuable lesson - where Caroline lives in my brain.

Announcer: Caroline deleted.

GLaDOS: Goodbye, Caroline. You know, deleting Caroline just now taught me a valuable lesson: the best solution to a problem is usually the easiest one. And I'll be honest. Killing you? Is hard. You know what my days used to be like? I just tested. Nobody murdered me. Or put me in a potato. Or fed me to birds. I had a pretty good life. And then you showed up. You dangerous, mute lunatic. So you know what? You win. Just go.

GLaDOS starts Chell's elevator moving up; she laughs softly

GLaDOS: It's been fun. Don't come back.
