The X-Files, Season 2

Mulder:
I was surprised to get your card. I had assumed our last contact... would be our last. Why are you here?

Mr. X:
Your investigation is faltering, Agent Mulder.

Mulder:
I've got a renegade Marine who may be violating every human rights provision...

Mr. X:
These people have no rights. In 24 hours all access to Folkstone will be restricted to military personnel. No press, no third-party monitoring.

Mulder:
What about Scully and me?

Mr. X:
You'll be called back to Washington on a priority matter.

Mulder:
They're making the camp invisible. Why?

Mr. X:
In case you haven't noticed, Agent Mulder, the Statue of Liberty is on vacation. The new mandate says if you're not a citizen you'd better keep out.
