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...

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!

Most test subjects do experience some, uh, cognitive deterioration after a few months in suspension. Now, you've been under for quite a lot longer, and it's not out of the question that you might have a very minor case of serious brain damage! But don't be alarmed, all right? Uh, although if you do feel alarmed, try to hold on to that feeling because that is the proper reaction to being told that you've got brain damage.

If the rules of physics no longer apply in the future, then god help you.

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.
