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

Cave Johnson: As founder and CEO of Aperture Science, I thank you for your participation and hope we can count on you for another round of tests. We're not going to release this stuff into the wild until it's good and damn ready, so as long as you keep yourself in top physical form, there will always be a limo waiting for you. Say goodbye, Caroline.
Caroline: Goodbye, Caroline!
Cave Johnson: She is a gem.

You look ugly in that jumpsuit. That's not my opinion; it's right here on your fact sheet. They said on everyone else it looked fine, but on you, it looked hideous. But still what does an old engineer know about fashion? Oh, wait, it's a she. Still, what does she know about - oh, wait. She has a medical degree. In fashion. From France.

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.

You know, I'm not stupid. I realize you don't want to put me back in charge. You think I'll betray you. And on any other day, you'd be right. The scientists were always hanging cores on me to regulate my behavior. I've heard voices all my life. But now I hear the voice of a conscience, and it's terrifying... because for the first time it's my voice! I'm being serious. I think there's something really wrong with me!
