Dr. Freeman, you really shouldn't be out there. At the moment of synapse, as I teleport, this chamber will be bathed in deadly particles that have yet to be named by human science. Perhaps when I have the leisure to do the work myself, I'll name one after you. That way you won't be completely forgotten.
When the singularity collapses, I will be far away from here. In another universe, as a matter of fact! You, on the other hand, will be destroyed in every way it is possible to be destroyed - and even in some which are essentially impossible!

Hard to see big picture behind pile of corpses.

Eat this, you outer-space octopus!

I didn't sign on for this shit. Monsters, sure, but civilians? Who ordered this operation anyway?

Come in, Cooper! Do you copy? Forget about Freeman, we're abandoning the base. If you have any last bomb targets, mark them on the tactical map. Otherwise, get the hell out of there! Repeat, we are pulling out and commencing airstrikes, give us targets or get below!

Eli Vance: "Why didn't they listen? We tried to warn them."
Scientist 2: "I never thought I'd see a resonance cascade, let alone create one."
Eli Vance: "Gordon, you're alive! Thank God for that hazard suit. I'm afraid to move him and all our phones are out. Please get to the surface as soon as you can and let someone know we're stranded down here. You'll need me to access the retinal scanners. I'm sure the rest of the science team will gladly help you."

I have no heart to give to Death. Perhaps, I'll give her the hearts of others. Yes, one-thousand should do it.

Scientist: "Do you think we should appeal to the alien authorities?"
Scientist 2: "Absolutely not!"

Please be advised that a noticeable taste of blood is not part of any test protocol but is an unintended side effect of the Aperture Science Material Emancipation Grid, which may, in semi-rare cases, emancipate dental fillings, crowns, tooth enamel, and teeth.

The Enrichment Center reminds you that the Weighted Companion Cube will never threaten to stab you and, in fact, cannot speak.

V: Mean to tell me you can pin the exact drug from just a whiff? Like a police dog, or what?
Johnny: I'd say more like a... a sommelier.

I have witnessed dar too much, and you have given me too little. Finally, I can see.

If history is to change, let it change. If the world is to be destroyed, so be it. If my fate is to die, I must simply laugh.

GLaDOS: "Look, you're wasting your time. And, believe me, you don't have a whole lot left to waste. What's your point, anyway? Survival? Well, then, the last thing you want to do is hurt me. I have your brain scanned and permanently backed-up in case something terrible happens to you, which it's just about to. Don't believe me? Here, I'll put you on:"
Strange voice: Hellooooooooo!
GLaDOS: "That's you! That's how dumb you sound! You've been wrong about every single thing you've ever done, including this thing. You're not smart. You're not a scientist. You're not a doctor. You're not even a full-time employee! Where did your life go so wrong?"

The Enrichment Center is required to remind you that the Weighted Companion Cube cannot talk. In the event that it does talk The Enrichment Centre asks you to ignore its advice.
