Mulder and Scully put the apartment under surveillance, but Colton has them taken off the job. Mulder finds Scully's necklace in Tooms' apartment and tries to call his partner, but her phone line has been cut. Tooms breaks into her apartment through a tiny air vent to kill her, but Mulder rushes there and apprehends him first. Tooms is put in an institution for the criminally insane where he begins to build another nest using newspaper. At the institution, Scully informs Mulder that medical tests on Tooms show an abnormal skeletal and muscle system, and a rapidly declining metabolism. When Tooms is given food through a slot in the door, he stares at the thin slot and grins.
