Meanwhile, in a Brooklyn apartment, Vietnam veteran Henry Willig is approached by a fellow ex-Marine, Augustus Cole. Suddenly a group of wounded Vietnamese appear and gun him down. Examining Willig's corpse, Mulder and Krycek find a scar on his neck and realize he was in the Special Forces stationed in Vietnam in 1970, and one of only two survivors, the other being Cole. They head to the VHA hospital in New Jersey where they discover that Cole was discharged, despite the fact that his doctor does not remember doing so. Mulder meets a mysterious informant named "X", who gives him information on a secret military project that Grissom performed where he eradicated the need for sleep through lobotomy. X provides him with the name of Salvatore Matola, a squad member who was mistakenly reported as killed in action.
