Uzi Doorman gives exposition about the Worker Drones, the elimination of biological life on Copper 9, and the arrival of the Disassembly Drones by orders of JCJenson, their parent company. In the present day (not too long after the Disassembly Drones arrive), Uzi presents her slideshow and her railgun, much to the horror of her peers and the apathy of her Teacher, who points out that the homework was a word problem on buying watermelons and that her repressed emotional baggage was only worth 2 points on the rubric. The railgun ends up malfunctioning, causing an explosion. Later, Uzi is in the sick bay after the accidental explosion, where she talks to Thad about her plan to sneak to the Spire of corpses to find the last part of her railgun, for it to function. Thad questions if it is necessary, seeing as Uzi's father, Khan Doorman, built doors specifically so they didn't need to do that "scary sounding emotionally repressed stuff". Uzi seems to get angry at Thad, then leaves, clarifying she is not angry, just "generally hormonal". At 3 AM, she gears up and steals the master door key from her dad's office. Uzi tries to sneak out but is met by him, who asks where she is going.

She says she wants to "join the WDF and hide behind doors like cowards". Khan takes her sarcasm seriously and gives her his wrench, a sentimental item to him. She is let out, after which Khan exclaims, "They grow up so fast..." After she sneaks out to the Corpse Spire, Uzi finds the component she needs but is attacked by Serial Designation N, who impales her hand with his nanite syringe and throws her against a wall. Uzi successfully ends up shooting N's head off with the railgun, but his head reassembles. In desperation, Uzi smacks N's head with a severed robot arm. N boots up blind and amnesiac, then responds, "Did you just slap me with that arm?" to which Uzi, who did not know Murder Drones
