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.

Well done. Here are the test results: You are a horrible person. I'm serious, that's what it says: "A horrible person." We weren't even testing for that. Don't let that horrible-person thing discourage you. It's just a data point. If it makes you feel any better, science has now validated your birth mother's decision to abandon you on a doorstep.
It's not out of the question that you might have a very minor case of serious brain damage.
If the Enrichment Center is currently being bombarded with fireballs, meteorites, or other objects from space, please avoid unsheltered testing areas wherever a lack of shelter from space-debris DOES NOT appear to be a deliberate part of the test.
Okay, almost there. On the other side of that wall is one of the old testing tracks. There's a piece of equipment in there we're gonna need to get out of here. I think this is a docking station. Get ready...

Good news: that is NOT a docking station. So there's one mystery solved. I'm going to attempt a manual override on this wall. Could get a bit technical! Hold on!

Ooh. It's dark down here, isn't it? They say that the old caretaker of this place went absolutely crazy. Chopped up his entire staff - of robots - all of them robots! They say at night you can still hear the screams - of their replicas. All of them functionally indistinguishable from the originals... No memory of the incident... Nobody knows what they're screaming about. Ab-solutely terrifying. Though obviously not paranormal in any meaningful way.
