The X-Files, Season 2

Skinner:
When I was eighteen, I, uh... I went to Vietnam. I wasn't drafted, Mulder, I- I enlisted in the Marine Corps the day of my eighteenth birthday. I did it on a blind faith. I did it because I believed it was the right thing to do. I don't know, maybe I still do. Three weeks into my tour, a ten-year-old North Vietnamese boy walked into camp covered with grenades and I, uh... I blew his head off from a distance of ten yards. I lost my faith. Not in my country or in myself, but in everything. There was just no point to anything anymore. One night on patrol, we were, uh... caught... and everyone- everyone fell. I mean, everyone. I looked down at my body from outside of it. I didn't recognize it at first. I watched the V.C. strip my uniform, take my weapon and I remained in this thick jungle... peaceful... unafraid... watching my- my dead friends. Watching myself. In the morning, the corpsmen arrived and put me in a body bag until... I guess they found a pulse. I woke in a Saigon hospital two weeks later. I'm afraid to look any further beyond that experience. You? You are not. Your resignation is unacceptable.

Mulder:
[realizing] You. [exhales heavily] You gave me Cancer Man's location. You put your life in danger.

Skinner:
Agent Mulder, every life, every day, is in danger. That's just life.
