The X-Files, Season 9

Scully:
These clothes that I'm wearing... they're my size. How the hell do you know my size?

Shadow Man:
Your size? I know your blood type, your resting heart rate, your childhood fear of clowns. I know the name of your College boyfriend, your true hair color, your ATM pin number, favorite charities, pet peeves. I know you spend too much time alone. And I know... that on one lonely night you invited Mulder to your bed.

Scully:
(her eyes well up with tears; speechless) Oh, my God.

Shadow Man:
I was as surprised as you are.

Scully:
(crying) Who authorizes you? I mean, what gives you the right? Who are you?!

Shadow Man:
I'm the future, Agent Scully. And I risked my life being here.

Scully:
Well, then why do it? I mean, why meet me?

Shadow Man:
Because you can reach Mulder. Mulder needs to know what I know or he may have no future. Perhaps no one will. Another car is parked on the main road, half a mile out. If I see that you haven't contacted Mulder in the next twenty-four hours, I disappear and you never see me again. Do you understand, lady?
