MULDER: Hey. I heard you were down here slicing and dicing. Who's the lucky stiff?

SCULLY: His name was Owen Sanders. He was reported as the fourth kidnap victim in Philadelphia until his body turned up last night looking like this.

MULDER: There's a Michael Jackson joke in here somewhere, but I can't quite find it.

MULDER: Scully, has it occurred to you that this might just be a... a little PR exercise?

SCULLY: I'm sorry?

MULDER: To divert attention from the fact that young black men are dying and nobody seems to be able to bring in a suspect? The perception being that nobody cares.

SCULLY: Mulder, not everything is a labyrinth of dark conspiracy, and not everybody is plotting to deceive, inveigle and obfuscate.

PENDRELL: Shouldn't we wait for Agent Scully? Just so I won't have to repeat myself.

MULDER: She's not coming.

PENDRELL: Why not?

MULDER: She had a date.

MULDER: Breathe, Agent Pendrell. It's with a dead man. She's doing an autopsy.

MARITA: Thousands of exotic species cross into US soil every day undetected. Bilge water is emptied into harbors. Produce sent through the mail. In practical terms, borders are little more than lines on maps.

SCULLY: It says here that the cause of death was undetermined.

MULDER: Yeah, undetermined, Scully, but not necessarily unknown.

MULDER: Scully, I think if you looked up from the microscope for a minute, you'd see that what's really missing is a motive.

SCULLY: The motive of any pathogen is to reproduce itself. And my job as a doctor is to find out if and how it is being transmitted.

MULDER: If this is a health crisis.

SCULLY: Death is a health crisis.

SCULLY: There are no charges against Mr. Aboah.

MULDER: We only arrested him because he ran when we tried to question him, and I want to know why he ran.

DUFF: Sir, if you had ever been beaten by the police or had your home burned to the ground for no other reason than being born then maybe you would understand why he ran and why you would run too.

MULDER: That man ran because he's hiding something. And no amount of tests you run on him, no science is going to find that. Excuse me.

SCULLY: Where are you going?

MULDER: To find someone who I know plotted to deceive, inveigle and obfuscate.

MINISTER: Even if I tell you what I know, you would never believe it.

MULDER: You'd be surprised at what I believe, sir.

SCULLY: So you're basing this theory on a folktale?

MULDER: It's just another way of describing the same truth, right? I mean all new truths begin as heresies and end as superstitions. We... we fear the unknown, so we reduce it to the terms that are most familiar to us, whether that's a folktale, or a disease, or a... conspiracy.

SCULLY: (voice over) My conviction remains intact that the mechanism by which Aboah killed and in turn survived, can only be explained by medical science, and that science will eventually discover his place in the broader context of evolution. But what science may never be able to explain is our ineffable fear of the alien among us; a fear which often drives us not to search for understanding, but to deceive, inveigle, and obfuscate. To obscure the truth not only from others, but from ourselves.
