For this next test, we put nanoparticles in the gel. In layman's terms, that's a billion little gizmos that are going to travel into your bloodstream and pump experimental genes and RNA molecules and so forth into your tumors. Now, maybe you don't have any tumors. Well, don't worry. If you sat on a folding chair in the lobby and weren't wearing lead underpants, we took care of that too.

As an impartial collaboration facilitator, it would be unfair of me to name my favorite member of your team. However, it's perfectly fair to hint at it in a way that my least favorite probably isn't smart enough to understand. Rhymeswithglue. Orange, you are doing very well.

Oh. Hi. So. How are you holding up? BECAUSE I'M A POTATO.

claps slowly three times

Oh, good. My slow-clap processor made it into this thing. So we have that. Since it doesn't look like we're going anywhere - Well, we are going somewhere. Alarmingly fast, actually. - but since we're not busy other than that, here's a couple of facts: he's not just a regular moron.

clap, clap

Good, that's still working. Hey, just in case this pit isn't actually bottomless, do you think maybe you could unstrap one of those long-fall boots of yours and shove me into it? Just remember to land on one foot...

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

How about I read you a story? Once upon a time there were three little pigs. I'm emphasising the past tense because they all died. Just like you will. I really like the story.
