DETECTIVE NETTLES: Look, Agent Mulder, look I'm really sorry I was such a hard ass back there. In this town, it's really tough to trust anyone. Truth is, I'd be happy to have you work on our investigation. Now this is Detective Gwen ----

MULDER: I'm working alone.

JOHN, THE SON: You know what we are.

MULDER: What are you?

JOHN, THE SON: He is the Father, I am the Son, and she is the Unholy Spirit.

MULDER: And the three of you killed Garret Lore.

JOHN, THE SON: No.

MULDER: Your fingerprints were found at the crime scene.

JOHN, THE SON: No. When a snake eats a fly, it's not murder. It just is.

MULDER: Frogs eat flies. Are you dead?

JOHN, THE SON: I never will be.

MULDER: Do you believe that?

JOHN, THE SON: Don't you want to live forever?

MULDER: Well, not if drawstring pants come back into style.

JOHN, THE SON: Look, what nobody realizes is that there is no afterlife. I know this. Listen, listen, I know this because when we prolong our lives by taking theirs all I see is such … horror in their eyes and that's because at that moment they're face-to-face with death and then suddenly they realize there's nothing else. There's no heaven. There's no soul. There's just rot and there's just decay. And I will never, ever, ever, ever have to face that.

MULDER: It's a stiff price, though. Look at yourself - drinking blood, living in darkness, unable to see your reflection in a mirror. Or is that just a myth?

JOHN, THE SON: I can't be seen in a mirror. Look… anything worth anything has a price and when I'm standing next to your deathbed looking as young as I look right now and I see that fear in your eyes at the moment of death … then, then tell me the price is too stiff.

MULDER: It's more likely I'll be looking in your eyes at the moment before they lead you into the gas chamber. That's a moment you won't have to face if you tell me where the others are.

JOHN, THE SON: Why would I? They're the only ones that can kill me.

MULDER: Well, if you are what you say you are, I know what can kill you.

DETECTIVE MUNSON: Why don't you go back to your hotel and get some sleep.

MULDER: I didn't check into a hotel room. I don't sleep anymore.

MULDER: The guards found no flammable materials? I had believed that this man's illness was psychological.

DR. BROWNING: There is a condition known as Gunther's Disease - congenital erythropoietic porphyria creating cutaneous photosensitivity.

MULDER: I'm familiar with porphyria. It's an affliction which causes lesions and blisters when skin is exposed to sunlight, not fourth degree burns. Sufferers may have a hema deficiency which can be supplemented by a small ingestion of blood, not the kind of bloodthirst this man had. It's probably ignorance of porphyria as a disease that led to the creation of vampire myths in Asia in the Middle Ages. I had dismissed the possibility of the actual existence of such a creature as myth.

DR. BROWNING: You are really upsetting me. On several levels.

KRISTEN: Are you about to ask what a normal person like me is doing in a place like this?

MULDER: How do you define normal?
