   The episode opens with Assistant Director Walter Skinner ( Mitch Pileggi ) unwell and horribly discolored in hospital . His veins are a sickly purple hue and are pulsating ominously . Suddenly , he goes into cardiac arrest and the doctors begin to pronounce him dead . 
   Twenty @-@ four hours earlier , Skinner loses a boxing match after experiencing a dizzy spell . He is discharged from the hospital but Fox Mulder ( David Duchovny ) and Dana Scully ( Gillian Anderson ) witness a bruise on his ribs growing . After trawling through security footage from the entrance to the J. Edgar Hoover Building , Scully recognizes a physicist by the name of Dr. Kenneth Orgel , who advises the Senate subcommittee on ethics and new technology , who stopped Skinner in the hall that same morning . Mulder and Skinner travel to the physicist 's house but find he is being held hostage . Mulder apprehends one of the kidnappers , who does not speak English . They release him since he has papers showing diplomatic immunity . Mulder does a background check on him anyway . 
   The background check leads Mulder to Senator Richard Matheson ( Raymond J. Barry ) , which results in a dead end . Scully discovers Skinner 's blood sample and , after checking , she finds that Skinner 's blood contains multiplying carbon . Meanwhile , Skinner ends up in hospital following a gunfight in the FBI parking garage . Mulder and Scully reunite at the hospital , where Mulder tells Scully that Skinner was investigating a health funding bill called S.R. 819 . Later , the physicist dies of the same carbon blood condition from which Skinner is sick . 
   Skinner remembers having seen , on numerous occasions , a bearded man who showed up suspiciously and who is actually running the scheme . He saves Skinner and sacrifices one of his own men . The case is closed and Skinner is , once again , aggravated with the agents , ordering them to report exclusively to Assistant Director Alvin Kersh ( James Pickens , Jr . ) . The bearded man was actually Alex Krycek ( Nicholas Lea ) , a rogue FBI agent who formerly worked for the Syndicate , who continues to control the potentially debilitating nanotechnology in Skinner 's system .

   The character of Walter Skinner had evolved over the course of The X @-@ Files ' sixth season . At the start of season six , however , the producers and writers felt that Skinner 's character was becoming " expendable " . With their transfer away from the X @-@ Files division , Mulder and Scully saw less and less of their former boss . Originally , John Shiban , the writer of the episode , wanted to infect Mulder with nanobots . However , he decided that since the audience knew Mulder would not be killed , this plot would not be very effective . In order to compensate for this loss , Shiban decided to re @-@ work Skinner back into the series mythology by putting him in Mulder 's place . Shiban , inspired by the 1950 noir film D.O.A. and its 1988 remake which he jokingly called " [ two ] pretty bad movies " , decided to craft an episode of The X @-@ Files around the conceit of " a guy who 's been poisoned [ and ] has only a short time to live and has to use that time to find out why and by whom he 's being murdered " . 
   Shiban began crafting his story by borrowing a nanobot plot that had been considered by various writers for several seasons . Shiban and the rest of the writers made it a point to give Alex Krycek control over Skinner . In this manner , Skinner once again became a mysterious character , one whose true loyalties were being tested . Shiban noted that , " [ Krycek 's control ] gives Skinner an agenda that Mulder doesn 't know about [ ... ] Which was something we ultimately used again in the seasonender [ sic ] , and will carry us into next year " .

   Originally , a " time @-@ consuming " fight scene between Skinner and Krycek was supposed to take place . The scenes were cut because of time @-@ constraints and budgetary reasons . However , Skinner 's boxing match proved easy to stage . Mitch Pileggi , who had boxed competitively in college , went for " refresher course [ s ] " at the Goosen Gym in Los Angeles . He later remarked , " It makes me happy that some people will assume there was a stunt double in the ring . There wasn 't ! [ ... ] We both had a pretty good time " . Location manager Ilt Jones called " S.R. 819 " the " damn parking lot episode " . He was tasked with finding the variety of parking lots used in the episode . He later joked that , " I started to wake up screaming about barriers and parking tickets and entrances and exit ramps " . 
   Pileggi had to endure long bouts of make @-@ up application . To create the principal illusion of monstrous veins , long black faux @-@ veins were glued onto his face , arms , and torso . Pileggi , who had had to endure little to no make @-@ up during the early seasons , noted that , " They did a beautiful job and [ the veins ] looked awesome , but man , I hated it ! I really don 't know how those guys on Star Trek or Babylon 5 can stand having that done to them every day . I just wouldn 't work if that 's what it took " . To show the nanobot infection progressing , special effects makeup supervisor John Vulich used two different make @-@ up sets . The two sets were then mixed together electronically in post @-@ production to give the effect of disease progression . The nanobots in the blood sample were designed on a computer and then cloned with an animation program . Composer Mark Snow 's score for the episode was inspired by Daniel Sackheim 's " big @-@ time feature @-@ like action " .
