G-Man:
The right man in the wrong place can make all the difference in the world.

G-Man:
Wake up, Mr. Freeman. Wake up, and smell the ashes.

Alyx Vance:
Dog, throw something bigger!

Dr. Wallace Breen:
Well, Dr. Freeman, under other circumstances I like to think we might have been able to work together in an atmosphere of mutual trust and respect. Certainly, judging from your brief tenure at Black Mesa while I was its Administrator, you showed every promise of becoming a valuable and productive contributor to the scientific process. And yet... I'm not sure what spurred you to it... but there is really no place in this enterprise for a rogue physicist.

Dr. Wallace Breen:
Your mentors are partly to blame, of course. My disappointment in Eli Vance and Isaac Kleiner is far greater than my sorrow over your unfortunate choice of career path. In a way, I suppose you could not have done otherwise. Who knows what seeds of iconoclasm they planted when you were young and gullible. But while they certainly share a great part of the responsibility for the recent troubles, it is you alone who have chosen to act with such willful disregard for humanity's future.

Dr. Wallace Breen:
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.

Dr. Wallace Breen:
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.

Dr. Judith Mossman:
They can tunnel through from their universe, but once they're here they're dependent on local transportation. If they knew what we're doing with entanglement - Oh, listen to me, I sound like a post-doc.

Dr. Isaac Kleiner:
Never fear, Gordon, she's de-beaked and completely harmless. The worst she might do is attempt to couple with your head. Fruitlessly!

G-Man:
Time, Dr. Freeman? Is it really that time again? It seems as if you only just arrived. You've done a great deal in a small time span. You've done so well, in fact, that I've received some interesting offers for your services.

G-Man:
Ordinarily, I wouldn't contemplate them... but these *are* extraordinary times.

G-Man:
Rather than offer you the illusion of free choice, I will take the liberty of choosing for you... if and when your time comes round again. I do apologize for what must seem to you an arbitrary imposition, Dr. Freeman. I trust it will all make sense to you in the course of... well... I'm really not at liberty to say. In the meantime... this is where I get off.

Barney Calhoun:
And if you see Dr. Breen, tell him I said -

Barney Calhoun:
- you!

Dr. Isaac Kleiner:
I see, your ATB-Suit still fits you like a glove. At least the glove parts do.
