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

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!

Dr. Eli Vance: A-hem! Alyx, why don't you take Gordon along and give him some practice with the Gravity Gun?
Alyx Vance: Sure. C'mon, Gordon. Let's go have some fun.
Dr. Judith Mossman: The Zero Point Energy Field Manipulator is not a toy, Alyx.
Alyx Vance: Ugh, let's get outta here.

Rise and shine, Mr. 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. The right man in the wrong place can make all the difference in the world. So, wake up, Mr. Freeman. Wake up and smell the ashes.

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!
