Scully: You've been our ally more times than I can say.
Skinner: Not the kind of ally that I could have been.
Scully: Sir, if this man poisoned you, you should be off your feet and under doctor's care.
Skinner: If this man poisoned me, I'm going to put a gun to his head, find out why, and ask him how he's going to make me well.
Skinner: Every minute of every day, we choose. Who we are. Who we forgive. Who we defend and protect. To choose a side or to walk the line. To play the middle. To straddle the fence between what is and what should be. This was the course I chose. Trying to find the delicate balance of interests that can never exist. Choosing by not choosing. Defending a center which cannot hold. So death chose for me.
Uniformed Cop: I'm not so sure you should be doing that.
Fox Mulder: [Flipping through documents on Dr. Orgel's desk] This is a crime scene. What would you rather I be doing?
Uniformed Cop: Uh, it's just that I'm concerned for Dr. Orgel's personal property and the preservation of evidence.
Fox Mulder: I would be a lot more concerned with the preservation of Dr. Orgel.
