Hand sanitizer

Hand sanitizer is a recurring object in Aza Holmes’s struggle with obsessive fears of infection, contamination, and loss of control. First used in rituals meant to make a wound feel safe, it later becomes something she swallows, including during a hospital stay after a serious accident. That reversal gives an ordinary cleaning product a frightening double role: it offers momentary relief while becoming part of the danger it is supposed to prevent.

Early Use in Contamination Rituals

Aza’s concern about infection attaches repeatedly to a callus and crack in the skin of her finger, a site she has reopened with her thumbnail since childhood. When the wound seems possibly contaminated, she checks and treats it rather than allowing uncertainty to remain. In one episode, she examines a damp-looking Band-Aid, considers whether the moisture could be infected drainage, squeezes hand sanitizer onto her fingertip, and washes her hands thoroughly before reopening the crack, expressing blood, and applying a fresh bandage. The sequence briefly eases her tension, but the doubt soon returns: she wonders whether she removed all the pus and whether there was pus at all.

The object therefore belongs to a repeating pattern rather than a completed act of hygiene. A small sign, such as moisture on a bandage, prompts catastrophic interpretations; cleaning and checking provide temporary relief, which does not settle the question for long. Aza’s fears also take in the microorganisms that live in and on the body. At White River High School, abdominal noises lead her to search online for information about Clostridioides difficile and to worry that an infection may be developing despite the absence of most symptoms. The sanitizer’s significance grows from this wider preoccupation: cleanliness cannot provide a final boundary between Aza and the living matter she fears.

Treatment and the Problem of Certainty

Dr. Karen Singh has asked Aza to consider exposure response therapy again. The exercises involve touching the callused finger to a dirty surface and then refraining from cleaning it or covering it with a Band-Aid. Aza remembers the fear the earlier attempt provoked and declines to try again. In that therapeutic context, hand sanitizer stands for the response she is being asked to resist: an immediate action that promises safety, but also keeps attention fixed on the possibility of contamination.

Medication introduces a related conflict. Aza sometimes avoids taking Lexapro because she is troubled by the idea that a pill might change who she is, even as she wants relief from what she experiences as an internal torment. After the accident, Dr. Singh stresses that medication needs to be taken consistently and later explains that Aza was not taking it as prescribed. The discussion does not treat the sanitizer as an isolated bad choice; it occurs within a larger struggle over how to care for a mind and body that Aza fears may not be fully under her control.

From Cleaning to Ingestion

The object’s role changes sharply when Aza begins to use it not only on her hands but in her mouth. At home, after changing a Band-Aid and becoming caught in renewed doubts about whether the wound is infected, she takes aloe-scented hand sanitizer from the medicine cabinet and swallows several mouthfuls. The act is bound up with fears that bacteria might affect her thoughts and that she cannot trust her own mind. The sanitizer’s alcohol and promise of cleanliness become part of an escalating compulsion, not a considered treatment for infection.

The crisis reaches a more dangerous form during Aza’s hospitalization for a lacerated liver. In bed, she becomes overwhelmed by thoughts about contamination and her inability to feel sure of herself. She gets up despite her pain, takes the IV pole for support, and presses the wall-mounted sanitizer dispenser. After rubbing foam into her hands, she puts some in her mouth; when her mother tells her to stop, she takes another mouthful and then a third. She gags and vomits, and her mother calls for help, reporting that Aza has drunk hand sanitizer.

The hospital staff initially interpret the ingestion as a search for alcohol. After Dr. Singh is contacted, she challenges that explanation and connects the episode to Aza’s mental-health crisis and the trauma of the accident. She also makes clear that hand sanitizer is dangerous to ingest, both because of its alcohol and because it contains chemicals that can kill. The distinction matters: the scene does not present the ingestion as ordinary drinking or as an effective way to prevent infection, but as a compulsion that has become physically hazardous.

Significance and Aftermath

Hand sanitizer’s changing function concentrates the novel’s tension between bodily care and bodily fear. On the skin, it is part of an attempt to control a possible infection; in the mouth, it becomes an extreme effort to answer fears that ordinary washing cannot quiet. The product’s familiar purpose makes the reversal especially stark: an object associated with cleanliness is turned against the body in pursuit of a certainty it cannot supply.

After the hospital crisis, Dr. Singh urges Aza not to fear the thought itself, distinguishing thought from action. That distinction does not make the earlier compulsion harmless, but it offers a way to understand the sanitizer without treating it as evidence of a deliberate wish to die or as proof that Aza has chosen her thoughts. Across its appearances, the object marks the difference between an intrusive fear, the ritual performed to neutralize it, and the bodily consequences when that ritual escalates. Its recurrence turns a mundane dispenser and medicine-cabinet bottle into a concrete measure of how urgently Aza seeks relief—and how little lasting certainty the act provides.
