CAPTAIN: Reactor's gone down.

MAN: Over here...

CAPTAIN: Engine room?

RADAR OFFICER: That won't work, captain. We've only got battery power.

CAPTAIN: I'm going down there. Prepare to surface at once!

RADAR OFFICER: Surface into what? We're under thirty-two feet of glacial ice.

MULDER: Why, why does he want to kill you?

SAMANTHA MULDER: Because I know how to kill him.

MULDER: How?

SAMANTHA MULDER: By piercing the base of his skull.

MULDER: That would kill anybody.

SAMANTHA MULDER: Yes, but this is the only way to kill him and it must be precise. I'm fairly sure it'll work.

MULDER: Fairly sure?

SAMANTHA MULDER: He's got powers I've never seen before. If it doesn't work, there's a chance you could die.

MULDER: From what?

SAMANTHA MULDER: Their blood is toxic, human exposure to it is fatal.

SAMANTHA MULDER: The men you've been seeking are the progeny of two original visitors, clones who have been attempting to establish a colony here since the late 1940's.

MULDER: A colony?

SAMANTHA MULDER: Loosely. The community, by necessity, is dispersed. There are clones identical to my parents living in virtually every part of the country.

MULDER: What are they trying to accomplish?

SAMANTHA MULDER: It's their belief that our stewardship of the planet is being forsaken, and that by default, they'll someday become the natural heirs.

SAMANTHA MULDER: Through hybridization, they've been working to erase that aspect which has forced the community to scatter... their identical natures.

MULDER: All the clones worked in abortion clinics, why?

SAMANTHA MULDER: Access to fetal tissue. Though the biologies are incompatible, they finally found a way to combine human DNA with alien DNA.

MULDER: And this man... why has he been sent to kill them?

SAMANTHA MULDER: The experiments weren't sanctioned. It was considered a dilution of their species, a pollution of their race. So a bounty hunter was dispatched to destroy them and terminate the colony.

SKINNER: What the hell is going on here, Mulder?

MULDER: This is my sister, Samantha Mulder.

SKINNER: What?

SCULLY: Well, then who is this man and what does he...

MULDER: He's an alien.

SCULLY: Is that what you're going to tell Skinner?

MULDER: I already told Skinner, that was the easy part. Now I got to tell my father.

X: You'll only win the war if you pick the right battles, Agent Mulder. This is a battle you can't win.

SKINNER: Did you tell her what she needed to know? How hard do you want to make this?

X: No harder than it has to be. I've killed men for far less.

SKINNER: You pull that trigger, you'll be killing two men. Now I want to know where Mulder is.

SKINNER: Agent Mulder took a commercial flight to Tacoma, Washington. From there, he caught a military plane to Deadhorse, Alaska. He used his F.B.I. credentials to charter a Rollagon all-terrain vehicle. It's still a ten-mile hike across the ice. These are the coordinates of his final destination.

SCULLY: How did you get this?

SKINNER: Unofficial channels.

ALIEN BOUNTY HUNTER: If I wanted to, I could've killed you many times before.

MULDER: Where is she?

ALIEN BOUNTY HUNTER: Is the answer to your question worth dying for? Is that what you want?

MULDER: Where is she? Just tell me where she is.

ALIEN BOUNTY HUNTER: She's alive. Can you die now?

SCULLY: Transfusions and an aggressive treatment with anti-viral agents have resulted in a steady but gradual improvement in Agent Mulder's condition. Blood tests have confirmed his exposure to the still unidentified retrovirus whose origin remains a mystery. The search team that found Agent Mulder has located neither the missing submarine nor the man he was looking for. Several aspects of this case remain unexplained, suggesting the possibility of paranormal phenomena... but I am convinced that to accept such conclusions is to abandon all hope of understanding the scientific events behind them. Many of the things I have seen have challenged my faith and my belief in an ordered universe...

...but this uncertainty has only strengthened my need to know, to understand, to apply reason to those things which seem to defy it. It was science that isolated the retrovirus Agent Mulder was exposed to, and science that allowed us to understand its behavior. And ultimately, it was science that saved Agent Mulder's life.

SCULLY: Thanks for ditching me.

MULDER: I... I'm sorry, I... I couldn't let you risk your life on this.

SCULLY: Did you find what you were looking for?

MULDER: No. No. But I... I found something I thought I'd lost. Faith to keep looking.
