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.
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.
There should be a portal device on that podium over there. I can't see it though. Maybe it fell off. Do you want to go and have a quick look?
Whoah! Hello? Can you see the portal gun? Also, are you alive? That's important; should have asked that first. I'm - do you know what I'm going to do? I'm going to work on the assumption that you're still alive, and I'm just going to wait for you up ahead. I'll wait - I'll wait one hour. Then I'll come back, and, assuming I can locate your dead body, I'll bury you. All right? Brilliant! Go, team! See you in an hour! Hopefully! If you're not - dead.
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...
smashes into wall
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!
smashes into wall, again
If the rules of physics no longer apply in the future, then god help you.
