MULDER: Crump? Is this what happened to your wife? This same thing? If you stop moving, you die?
SCULLY: How did Crump know to avoid the roadblock?
CAPTAIN: That's the question. I was hoping your Agent Mulder would manage to steer him toward it, but...
SCULLY: Maybe Agent Mulder steered him away from it.
CAPTAIN: Why would he do that?
SCULLY: Maybe he knew something that we don't.
MULDER: Crump? Crump, what else can you tell me about what's happening to you?
CRUMP: Mr. Crump. You call me by my last name, you say "mister" in front of it.
MULDER: "Mister." I got you.
CRUMP: Not Crump. Mr. Crump.
MULDER: I can think of something else I'd like to call you. I could put "mister" in front of that, too if you'd like.
CRUMP: You know, what kind of name is Mulder, anyway? What is that, like... like, Jewish?
MULDER: Excuse me?
CRUMP: Jewish... It is, right?
MULDER: It's Mr. Mulder to you, you peanut-picking bastard. Now, Mr. Crump what can you tell me about what's happening to you?
MULDER: Crump... It's west. Huh, west? You got to head west. It's just like you did with your wife. You took her and you headed west. It's not just motion; it has to be in one direction. Is that right? What the hell happened to you?
SCULLY: Okay. Mulder, you know what ELF waves are? Extremely low radio transmissions?
MULDER: Yeah. It uses an antenna, like, 50 miles long. The military uses it to communicate with the trident submarines, Project Seafarer, Project Haarp.
SCULLY: Well, Seafarer has an antenna array stretching beneath the edge of Patrick Crump's property. Now, ELF fields have been shown to... To produce biological effects in human tissue inducing electrical currents, altering chemical reactions.
MULDER: Not to mention that as a potential weapons application it's been referred to as "electrical nerve gas" or may be behind the so-called "Taos Hum."
SCULLY: What if some overload some... Some hum from this system could somehow match the resonant frequency of the human skull? I mean, what if it could induce a like hum that could... That could somehow exert a rising pressure on the labyrinth of the inner ear in a sense shattering it?
MULDER: But with constant movement somehow ameliorating that pressure making it bearable. But why only westward movement?
