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!

Great job, Gordon! Throwing that switch and all, I can see your MIT education really pays for itself.

Well, Gordon, I see your HEV Suit still fits you like a glove. At least, the glove parts do.

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.

Rise and shine, Mister Freeman. Rise and... shine. Not that I... wish to imply you have been sleeping on the job. No one is more deserving of a rest, and all the effort in the world would have gone to waste until... well, let's just say your hour has... come again.
