A Quote from Portal 2
GLaDOS, Announcer
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.

All these spheres are made of asbestos, by the way. Keeps out the rats. Let us know if you feel a shortness of breath, a persistent dry cough, or your heart stopping. Because that's not part of the test. That's asbestos. Good news is, the lab boys say the symptoms of asbestos poisoning show a median latency of forty-four point six years, so if you're thirty or older, you're laughing. Worst case scenario, you miss out on a few rounds of canasta, plus you forwarded the cause of science by three centuries. I punch those numbers into a calculator, it makes a happy face.
Crushing's too good for him. First he'll spend a year in the incinerator. Year two: Cryogenic refrigeration wing. Then TEN years in the chamber I built where all the robots scream at you. THEN I'll kill him.
You know what I have too many of around here? Monitors. I was just thinking earlier today I wish I had fewer monitors that were working. So you're actually helping me by smashing them.
Just a heads up: we're gonna have a superconductor turned up full blast and pointed at you for the duration of this next test. I'll be honest - we're throwing science at the wall here to see what sticks. No idea what it'll do. Probably nothing. Best-case scenario, you might get some superpowers. Worst case, some tumors, which we'll cut out.
Good work getting this far, future-starter! That said, if you are simple-minded, old, or irradiated in such a way that the future should not start with you, please return to your primitive tribe and send back someone better-qualified for testing.
