What's my theory? My theory is you don't know Mulder at all. You never did. (flips his badge over, showing his name) "John Doggett." Kersh's task force leader. You might have just introduced yourself.
(voiceover) We live in a darkness of our own making... blind to a habitant world all but unseen by us. A world of beings traveling through time and space imaginable to us only as flights of fancy. Who are these beings we dare to imagine but fear to accept? What dark work goes on inside their impossible machines... cloaked from us by invisible forces? If they know our secrets, why can't we know theirs?
(tearing up) Look, we are being hampered here by the FBI, by John Doggett, by doubt, by our own mistrust. Whatever it is, it is working... as long as we let it.
You told me Mulder wouldn't allow it. Wouldn't let me ruin my career over this. Over him. But what about you, Scully? I mean, my god, you've got even more at stake.
The more basic answer is what we're dealing with here is simply a man. A psychotic killer with a deformed foot. You're familiar with the principle of Occam's Razor?
Yeah. You take every possible explanation and you choose the simplest one. Agent Mulder used to refer to it as "Occam's Principle of Limited Imagination."
(unholsters his gun) First thing you're supposed to say is: "What nanny-cam?" (pushes the door open suddenly, knocking the man hiding behind it to the ground)
(voiceover) The passage of time in prisons is not in a cell of brick and mortar but in one of hopes dashed and tragedies unaverted. How precious, then, the chance to go back only to discover that in facing the past you must face up to yourself... that exiting the prison of time doesn't free you from the prison of your own character... one from which there is no escape.
