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.

Cave Johnson: As founder and CEO of Aperture Science, I thank you for your participation and hope we can count on you for another round of tests. We're not going to release this stuff into the wild until it's good and damn ready, so as long as you keep yourself in top physical form, there will always be a limo waiting for you. Say goodbye, Caroline.
Caroline: Goodbye, Caroline!
Cave Johnson: She is a gem.

If you feel liquid running down your neck, relax, lie on your back, and apply immediate pressure to your temples. You are simply experiencing a rare reaction in which the Material Emancipation Grill may have emancipated the ear tubes inside your head.

The two of you have formed an excellent partnership, with one of you handling the cerebral challenges and the other ready to ponderously waddle into action should the test suddenly become an eating contest.

They're not even your screens to break! It's vandalism! It's pure vandalism! You wouldn't do this if it was your house, would you? If I came around to your house smashin' your telly, you'd be furious. And rightly so. Unbelievable.
