Summary

At 0730, Gwendy and Kathy prepare to leave Eagle Heavy, the station where they've been staying. Before suiting up, Gwendy eats the chocolate she saved. When Kathy asks if there's another, Gwendy opens the button box and pulls the lever, but the platform slides out empty. Gwendy remarks that the box gives and sometimes doesn't. She feels clear-headed with the chocolate in her system—the confusion that once required her to label her gloves RIGHT and LEFT is gone, though she suspects it may return.

Kathy notices Gwendy smiling and asks why. Gwendy says she's excited about her first spacewalk, though Kathy's unspoken thought is that it will also be her last.

Gwendy confirms that Mission Control's computers are off until the return, so no one will register the airlock opening. They float into the airlock and sit on benches, knees touching. Kathy instructs Gwendy to prebreathe—sixty inhales and exhales—to purge nitrogen from her system. Gwendy gets slightly woozy from the rapid breathing, but Kathy reassures her it's normal.

Gwendy confirms she's sure of the plan. The cover story is in place: she and Winston skipped breakfast, which no one will find unusual since they're passengers with the luxury of sleeping in. No one will worry until at least 1000 hours, by which time Kathy will be back aboard the MF. A search will follow, and by 1400, Sam Drinkwater will report the VIPs missing, possibly drifted away during a spacewalk.

After two minutes of prebreathing, they don their helmets. Gwendy secures her own, checks the green light at mouth level, dons her gloves, and waits for a second green light. She makes a thumb-and-finger circle to Kathy, who returns the gesture. Kathy closes the door to Eagle Heavy, and the airlock begins to depressurize.

Kathy tells Gwendy to set her suit temperature to maximum hot and adjust down. The heat will last nearly six hours—as long as her breathable air—and Kathy's shrug implies Gwendy won't feel it when it ends.

Gwendy knots the drawstring bag holding the button box around one of the carabiners on her belt. Kathy attaches the buddy cable to the other. They are now tethered together like scuba divers.

Kathy asks if Gwendy is ready to EVA. Gwendy makes the circle gesture again, thinking that she's been waiting for this since she first looked through her telescope over fifty years ago, even if she didn't know it at the time. Kathy warns her not to wait too long to lower her outer visor, as the night pass ends in about seven minutes.

At 0748, Kathy turns the red lever in the center of the airlock's outer door and pulls it. The airlock opens on the stars.

Character Development

Gwendy reaches a state of calm resolve. The chocolate gives her mental clarity, and she faces her fate without hesitation. Her reflection about the telescope reveals that this moment is the culmination of a lifelong journey she only now understands. She's no longer the woman who needed labels on her gloves—at least for now.

Kathy acts as the steady instructor, walking Gwendy through each step of the EVA procedure. Her unspoken thought—first and last—shows she understands the weight of what they're doing, yet she remains professional and supportive.

Themes, Symbols, or Motifs

Button box emptiness: The box's refusal to produce a chocolate for Kathy signals that its power is spent. It feels dull and resigned to its fate, mirroring Gwendy's own acceptance.

Sacrifice: Gwendy's plan to drift away during a spacewalk is a deliberate, quiet sacrifice—one disguised as an accident.

Cover story deception: The elaborate story about skipped breakfasts and a tragic spacewalk accident shows how carefully Gwendy and her allies have constructed this ending.

Chocolate as clarity: The chocolate restores Gwendy's mental sharpness, allowing her to face the final moments with a clear mind.

Lifelong culmination: Gwendy's realization that she's been waiting for this since her first look through a telescope ties her entire life's arc to this single moment.

Tethering and bonding: The buddy cable and carabiner physically connect Gwendy to Kathy and to the button box, symbolizing the bonds that carry her to the end.

Acceptance of fate: Gwendy's smile, her steady answers, and her readiness all reflect a deep acceptance of what's to come.

Why This Chapter Matters

This chapter is the threshold moment of the novel—the point where Gwendy's plan moves from intention to action. It shows the mechanics of the cover story, the emotional weight of her decision, and the quiet dignity with which she approaches her end. The button box's emptiness marks the conclusion of its role in her life, and the final image of the airlock opening on the stars is both literal and symbolic: Gwendy is about to step into the unknown.

Study Questions

1. Why does the button box deliver nothing when Gwendy tries to give Kathy a chocolate?

The box has fulfilled its purpose. It feels dull and powerless, as if resigned to its fate. Gwendy's comment that the box gives and sometimes doesn't acknowledges that its power is no longer at her disposal—its role in her story is complete.

2. What is the cover story Gwendy and Kathy have agreed upon, and why is it necessary?

The story is that Gwendy and Winston skipped breakfast (unremarkable for passengers), no one will worry until at least 1000 hours, and by 1400 Sam Drinkwater will report the VIPs missing, possibly drifted away during a spacewalk. The story is necessary to make Gwendy's death look like an accident rather than a deliberate act.

3. What does Gwendy's thought about the telescope reveal about her state of mind?

It reveals that she sees this moment as the culmination of a lifelong journey. She's been moving toward this since she first looked through a telescope over fifty years ago, even if she didn't recognize it at the time. This gives her a sense of purpose and acceptance rather than fear.
