Man of few words, aren't you?

Dr. Isaac Kleiner: We can't leave without Lamarr. She's around here somewhere...
Alyx Vance: Come on, Dr. Kleiner. We can find you another pet headcrab.
Dr. Isaac Kleiner: No! There's only one Hedy!

I'd like to take a moment to address you directly, Dr. Freeman. Yes. I'm talking to you, the so-called One Free Man. I have a question for you. How could you have thrown it all away? It staggers the mind. A man of science, with the ability to sway reactionary and fearful minds toward the truth, choosing instead to embark on a path of ignorance and decay. Make no mistake, Dr. Freeman. This is not a scientific revolution you have sparked... this is death and finality. You have plunged humanity into freefall. Even if you offered your surrender now, I cannot guarantee that our benefactors would accept it. At the moment, I fear they have begun to look upon even me with suspicion. So much for serving as humanity's representative. Help me win back their trust, Dr. Freeman. Surrender while you still can. Help ensure that humanity's trust in you is not misguided. Do what is right, Dr. Freeman. Serve mankind.

We now have direct confirmation of a disruptor in our midst, one who has acquired an almost messianic reputation in the minds of certain citizens. His figure is synonymous with the darkest urges of instinct, ignorance and decay. Some of the worst excesses of the Black Mesa Incident have been laid directly at his feet. And yet unsophisticated minds continue to imbue him with romantic power, giving him such dangerous poetic labels as the One Free Man, the Opener of the Way. Let me remind all citizens of the dangers of magical thinking. We have scarcely begun to climb from the dark pit of our species' evolution. Let us not slide backward into oblivion, just as we have finally begun to see the light. If you see this so-called Free Man, report him. Civic deeds do not go unrewarded. And contrariwise, complicity with his cause will not go unpunished. Be wise. Be safe. Be aware.

Welcome. Welcome, to City 17. You have chosen, or been chosen, to relocate to one of our finest remaining urban centers. I thought so much of City 17, that I elected to establish my administration, here, in the citadel, so thoughtfully provided by our benefactors. I am proud to call City 17 my home. And so, whether you are here to stay, or passing through to parts unknown, welcome, to City 17. It's safer here.
