Summary

The chapter opens with a flashback to Carmen's infancy. Their mother was convinced that Nora, then a toddler, wanted to harm her baby sister. Mama believed Nora tried to smother Carmen with stuffed animals and once tipped over the baby carriage, causing Carmen to tumble out and break her pinky finger. For weeks, Mama forbade Nora from being alone with Carmen. Their grandmother, skeptical of the drama, eventually intervened: while Mama napped, she let Nora touch the baby. Nora gently explored Carmen's face, squeezed her calves, and rubbed grass on her skin, claiming possession. Then she pinched Carmen, who wailed. After that, the sisters became inseparable until their teenage years, when Carmen lost interest in science and told Nora to stop talking about her experiments.

In the present, Carmen and Skipper appear unannounced at Nora's laboratory, dirty and exhausted. Nora's first instinct is paranoia—she wonders if Renewal is trying to flush her out, given the anonymous threats she's been receiving. But she quickly recognizes her sisters and abandons her experiment. She notices how thin Carmen is and how Skipper looks sunburned. Nora reflects on how people are not single selves but a series of moments, yet she knows her sisters deep in her body. Overwhelmed with joy, she hugs them.

Nora summons a car, then cancels it and summons a different one—a precaution that has become habit. At her apartment, she watches them take in her life: the plants on the windowsill, the colorful clothes she offers to lend, the tart she baked. She wants them to see she's doing okay, even though her position is precarious. She talks nervously, offering food and a shower, feeling alien as the words tumble out.

Carmen explains their worry when they didn't hear from her and the journey they undertook. Nora is dismayed to learn they found the coded message she never intended for them to see; she had only hoped they might tell her friend Marcus or the authorities. Carmen reveals she brought blight variant samples, seeds, and a wad of gum. Nora's heart leaps—Carmen did it. But the tension is unbearable. Skipper retreats to the bedroom, then returns holding a chipped mug with a child's drawing of bumblebees, accusing Nora of leaving it behind. Nora kisses the mug and apologizes. Skipper says, “I don't even know you,” and Nora understands, because sometimes she doesn't know herself.

Nora notices the fungus on Carmen's neck and offers to make a medical appointment, noting it's free. Carmen resists, saying she didn't have money for an operation, but eventually accepts Nora's help. Nora reflects on her anxiety, which has worsened over the past half year, and her argument with her boss, Rafael Aguirre, about methodology—an argument she couldn't resolve because she couldn't tell him what she learned in the vault. She's been having terrible headaches, as if her skull is too small for her mind.

Carmen asks Nora to explain what happened, and Skipper insists she owes them that much. Nora searches for the beginning, thinking of herself as a child sitting in a field near the ocean. Carmen prompts her: “You were looking for plants that were blight resistant.” Nora agrees, and this is where she begins.

Character Development

Carmen: She appears physically diminished—thin, with fungus on her neck—but she has taken initiative, traveling to find Nora and bringing the blight samples. Her independence is strong; she resists Nora's help at first, but eventually accepts it. Her tears upon seeing Nora show her emotional vulnerability.
Skipper: She is angry and hurt, confronting Nora with the mug and saying she doesn't know her. Her frustration stems from the risk they took and the secrecy Nora maintained. She demands an explanation, representing the need for truth.
