I, uh… have the distinction of being one of three men to have exterminated such a creature. I was with the C.I.A. in Vietnam. A UFO was sighted for five nights over Hanoi. The marines shot it down and brought it to us. Maybe… it didn't know what a gun was or perhaps they don't show emotion but that… innocent and blank expression as I pulled the trigger has haunted me… until I found you. That's why I come to you, Mr. Mulder, and will continue to come to you to atone for what I've done.
