Work hard, increase production, prevent accidents and be happy." At home, THX takes his drugs and watches holobroadcasts while engaging with a masturbatory device. LUH secretly substitutes pills in her possession for THX's medications, causing him to develop nausea, anxiety, and sexual desires. LUH and THX become involved romantically and have sex. THX later is confronted by SEN, who attempts to arrange that THX become his new roommate, but THX files a complaint against SEN for the illegal shift pattern change. Without drugs in his system, THX falters during a critical and hazardous phase of his job, and a control center engages a "mind lock" on THX which raises the level of danger. After the release of the mind lock, THX makes the necessary correction to that work phase.

Chased by the police robots, THX and SRT are trapped in a control center, from which THX learns that LUH has been "consumed", and her name has been reassigned to her fetus, numbered 66691, in a growth chamber. SEN eventually escapes to an area reserved for the monks of OMM, where a monk notices that SEN has no identification badge. SEN attacks him and later wanders into a child-rearing area, strikes up a conversation with children and sits aimlessly until police androids apprehend him. THX and SRT steal two cars. SRT struggles with figuring out how to drive the car. When SRT finally gets the car to move, SRT immediately
