In Baltimore, a deputy administrator for the EPA picks up a woman named Shannon McMahon in a bar; as he takes her home, she forces him to drive into a river and prevents him from swimming to safety. Kersh, accused of having secret meetings with Rohrer and Crane, is the subject of an internal investigation by Doggett. Assistant Director Brad Follmer, an old flame of Reyes', lets her know that the security video of the chase in the parking garage has been falsified. McMahon shows up at a Maryland water reclamation plant and drowns a worker there. Mulder disappears and Skinner asks Doggett to drop the Kersh investigation in the interest of the safety of Scully's child, leaving only Reyes to back his story about what happened.
Reyes tells Follmer that if the investigation is dropped, she'll get bumped off the X-Files and returned to the New Orleans field office. Doggett calls his old military buddies to try to get some information on Rohrer; they include McMahon. William apparently has telekinesis, as he makes his mobile turn without touching it. Scully changes her mind about wanting the Kersh investigation dropped, and someone tips off Reyes about the EPA administrator's death. Scully's autopsy finds evidence of McMahon's grip.
Follmer rats on the unauthorized autopsy to Kersh. McMahon tries to see Scully at her apartment and makes a couple of visits to the FBI building, once as Scully and Reyes are finishing up the autopsy; the administrator's body goes missing right after this visit as Follmer tries to catch Doggett in the act. Follmer denies tipping off Reyes about the death. Skinner and Doggett investigate the reclamation plant after The Lone Gunmen discover that the administrator was receiving encrypted files from the drowned plant worker. Follmer and his agents show up as Doggett and Skinner try to escape with files from the worker related to something called chloramine (a substance the administrator had mentioned as a government additive and expressed suspicion about). Doggett is hiding out in a water tank when McMahon begins to pull him into the depths. To be continued...
