Ordinarily, I wouldn't contemplate them... but these are extraordinary times.

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.

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.

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!

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