More soldiers killing superiors in this episode, which seems to have been a semi-regular occurrence throughout the X Files. Here though we have old mate Teager who seems to have the ability to disappear in plain view, which makes it quite difficult for him to be caught. Having disposed of a couple of victims, Mulder eventually comes to the conclusion that he has gained the ability to make himself a blind spot, which is not as good as invisibility, but pretty damn handy when you want to slip away virtually unnoticed.
The part of the story regarding POWs in Vietnam still being alive but ignored by the government seems to be casually swept under the carpet at the important parts of the episode. 3.5/5
