Nic and Z.’s romantic relationship

Nic and Z.’s romantic relationship is marked by a breakup, a reunion, and the return of drug use. Its significance lies in the sharp contrast between two responses to heartbreak: when Z. first leaves Nic, he calls his sponsor and accepts help; after they reunite, he joins her in using drugs and describes their relationship through promises that addiction repeatedly renders unreliable. The book presents their intimacy not as a separate refuge from Nic’s illness, but as a bond increasingly caught up in its cycles of hope, relapse, and crisis.

A brief romance and its first ending

Nic initially tells his family about a new romance with Z. only in fits and starts. The relationship is short, and when Z. breaks it off, Nic is left close to tears. The narrator recalls that, in earlier periods, Nic might have responded to such distress by calling a dealer or drug-using friends, or by looking for a joint or a beer. This time, he calls Randy, his sponsor.

Randy answers the breakup not with an attempt to analyze it but with an invitation to come over for a bike ride. Nic and Randy ride for three hours up Temescal Canyon, twice. Afterward Nic sounds elated and says he will be all right. The scene gives the relationship’s first ending a consequence beyond the loss itself: it tests whether Nic can endure romantic pain without turning immediately to drugs, and, for that moment, recovery support helps him do so.

Reunion and renewed intimacy

Z. later returns to Nic’s life. When he confesses that he has begun using again, the narrator recognizes her as the girl who had broken his heart after their brief relationship, before his previous relapse. Nic is now with her again and has moved out of his new apartment into hers. The reunion therefore follows a separation and an earlier period of distress, but the book does not describe a settled reconciliation or explain how the couple resumed their relationship.

Their renewed closeness becomes directly bound up with drug use at a party. Nic tells his father that Z. did a line and asked him to join her; he says he did not want her to go out alone. This is the reason Nic gives for participating, not evidence that one partner alone caused the relapse. He reports that the two have been high for three days, using speedballs, a combination of heroin and cocaine, as well as methamphetamine. The disclosure turns the reunion from an apparent return to intimacy into a scene of shared danger.

Promises inside the relapse

After three days of using, Nic says he has taken a sleeping pill to come down, acknowledges that he has made a serious mistake, and says he will stop. His assurance does not lead to an immediate return to treatment. In a later call, he tells his father that he and his girlfriend have finished their methamphetamine supply and that it is over. He resists the prospect of rehab and presents their relationship as a safeguard: she will not let him use, he will not let her use, they have made a vow, and they will call the police on each other if either slips. He also says she will leave him if he uses again.

These promises echo assurances Nic has made before that circumstances will be different. Their shared vow does not establish that either partner can control the other’s drug use; instead, it becomes part of Nic’s account of why he can remain outside treatment. The relationship is thus shown carrying contradictory meanings for him: Z. is someone he has returned to and someone he describes as a partner in mutual protection, while their renewed life together is also taking place amid sustained drug use. The narrative does not present romance as a cure for addiction or claim that Z. alone is responsible for Nic’s choices.

Crisis and rupture

The relationship later enters a more openly destructive phase. Z. tells the narrator that Nic dropped her at a market in Pacific Palisades at 5:45 in the morning and took her car to his mother’s house, intending to break in and steal a computer. He had promised to return within fifteen minutes, but four hours passed without his return. Z. becomes frantic and worried, and calls the police, who have no record of him. Her fear and anger register the distance between the couple’s earlier vows and the increasingly chaotic circumstances of Nic’s drug use.

Nic is eventually found inside the garage, where he has broken in and is piling belongings into shopping bags. He has become confused and locked himself in. Z. hears from him by telephone and, enraged, begins packing his clothes, telling the narrator that they will be outside on the porch. This is the clearest ending the book gives their renewed relationship: not a negotiated separation, but an abrupt expulsion from the shared domestic space after Nic’s break-in and attempted theft. His mother gives him a choice between the police and returning to rehab. The immediate crisis shifts the focus from the couple’s promises to the family’s effort to get Nic into treatment.

Narrative significance

The relationship’s changing role is measured through Nic’s responses to distress. After the first breakup, he reaches out to Randy and goes cycling; after reuniting with Z., he describes joining her drug use and later relies on mutual promises as a reason not to return to rehab. The contrast does not reduce the relationship to a single cause of relapse. Rather, it shows how the same bond can be experienced as companionship, a source of emotional pain, and a setting in which drug use is shared.

The book also refuses a romantic resolution. Z.’s return does not restore Nic’s earlier sobriety, and their vows do not prevent the next crisis. By the time she packs his clothes, intimacy has given way to fear, anger, and an urgent choice imposed by his family. The relationship’s arc therefore remains inseparable from the book’s larger account of addiction as recurring and resistant to easy closure: love and promises matter, but they cannot by themselves make Nic stop using or guarantee his safety.
