The chapter opens with a retrospective on Sharon’s employment at OrganInc Farms, explaining that she and Jimmy’s father met while working on the same pigoon‑related project. Sharon’s role was to study harmful proteins and engineer receptor blockers that act as “locks” on pigoon cells, preventing microbes from entering. She demonstrates this to Jimmy on her computer, showing colorful images of cells and microbes that resemble candy jars, and describes the process in simple terms. Jimmy asks why she no longer makes the locks; she replies that she quit to stay home with him, though her tone is weary and she smokes a cigarette while speaking. Jimmy worries about the pigoons being infected, but Sharon dismisses his concern, saying other people now handle it. She allows Jimmy to manipulate the computer programs, letting him play “war games” where cells battle microbes, and reassures him that any data loss is irrelevant because the material is outdated. Occasionally, Sharon indulges in the computer herself, which Jimmy enjoys and sees as a moment of genuine mother‑child connection.

The narrative then shifts to Jimmy’s memory of his mother’s erratic work schedule. When Jimmy entered OrganInc School full‑time in first grade, Sharon stopped working at the lab, a change Jimmy cannot explain. He recalls that before Sharon’s return, a live‑in caretaker named Dolores, originally from the Philippines, lived with them. Dolores called him “Jim‑Jim,” cooked his eggs just right, sang to him, and provided affection. She was eventually sent away once Sharon resumed her role as the primary mother figure, leaving Jimmy to miss her.

The latter half of the chapter is presented from Snowman’s (Jimmy’s) perspective, offering a vivid image of his mother at the kitchen table after school. She sits in a magenta bathrobe, coffee untouched, smoking and staring out the window. Lunch is never ready; she gives flat, directive instructions (“The milk’s in the fridge…”) and appears tired, possibly ill. When Jimmy asks if she is infected like the cells he learned about, she hesitates, first denying and then half‑confessing, only to withdraw. Jimmy strives to amuse her with school stories, crude jokes, and physical antics (e.g., putting peanut butter on his nose), which alternately irritate and occasionally elicit a smile. Rarely, she prepares an elaborate, open‑face peanut‑butter‑and‑jelly sandwich with a smiley face, dressing up and looking at Jimmy with “eyes bluer than blue.” These moments are likened to a polished porcelain sink—clean, hard, and demanding appreciation.

As Jimmy grows older, he learns to provoke varied emotional reactions from his mother, ranging from angry outbursts and coffee‑cup throws to crying, slamming doors, and occasional slaps followed by embraces. He simultaneously feels love, guilt, and a perverse satisfaction at having this impact, fearing that he might have gone too far. This complex dynamic underscores his ongoing obsession with his mother’s mood and his own capacity to affect it.
