Portal 22011

GLaDOS:
[Chell wakes up after defeating the final boss] 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.

[beep]

Announcer:
Caroline deleted.

GLaDOS:
[her old self] 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.
