Summary

Gaspery stands beneath a weeping willow on the grounds of the 1918 estate, staring at his device. A single word pulses on the screen: Return. He briefly entertains a fantasy of staying in this foreign century—burying the device, cutting out his tracker, and taking his chances with the flu pandemic—but even as the thought crosses his mind, his fingers are already entering the code. He is leaving.

When he opens his eyes in the harsh light of the Time Institute, he is unsurprised to find armed figures in black uniforms waiting for him. What does surprise him is the presence of Olive Llewellyn’s publicist, Aretta, standing beside Ephrem. The two are the only ones out of uniform. Ephrem orders Gaspery to remain inside the time machine. At the back of the room, Gaspery sees Zoey being restrained by two men.

Gaspery admits to Aretta that he never suspected her. She replies that she is competent at her job and doesn’t go around telling people she’s a time traveler. He then apologizes to Zoey for tricking her, explaining that he told her he was going to 1918 as part of the investigation, but his real purpose was to save Edwin St. Andrew from dying in an insane asylum. Zoey is escorted out before she can respond.

Ephrem asks if Aretta has an updated bio. She reads from her device: thirty-five days after Gaspery’s visit, Edwin St. Andrew died in the 1918 flu pandemic. Ephrem points out that if Gaspery hadn’t changed the timeline, Edwin would still have died of the flu—just forty-eight hours later and in an insane asylum. He asks Gaspery if he sees how pointless the intervention was. Gaspery replies, “You’re missing the point.”

Ephrem, looking tired and strained, asks if Gaspery has anything to say. Gaspery asks if they’ve reached last words already. Ephrem confirms that these are his last words in this century, on the moon, and that Gaspery will be traveling some distance and not returning. Gaspery asks Ephrem to take care of his cat. Ephrem blinks, then agrees. Gaspery thanks him and adds that he would do it again without hesitation. Ephrem sighs, says “Good to know,” and raises a glass bottle he had been holding behind his back. He mists something in Gaspery’s face—a sweet scent, a dimming of lights, and Gaspery’s legs give way.

Key Events

  • Gaspery returns to the Time Institute after his unauthorized trip to 1918.

  • Armed guards in black uniforms are waiting, along with Ephrem and Aretta.

  • Aretta is revealed to be a time traveler working with the Institute.

  • Gaspery apologizes to Zoey for deceiving her about his mission.

  • Aretta reads Edwin St. Andrew’s updated bio: he died of the flu thirty-five days after Gaspery’s visit.

  • Ephrem explains that Edwin would have died of the flu anyway, just forty-eight hours later and in an asylum.

  • Ephrem sentences Gaspery to exile—he will travel far and never return.

  • Gaspery asks Ephrem to care for his cat and declares he would act the same way again.

  • Ephrem administers a sedative via a mist, and Gaspery collapses.

Character Development

Gaspery shows a striking blend of recklessness and conviction. His brief fantasy of staying in 1918 reveals a longing for escape, but he immediately dismisses it, suggesting his commitment to his own moral code outweighs his desire for freedom. When confronted, he does not apologize for his actions—only for the deception he used on Zoey. His final words, “I’d do it again,” cement his stubborn idealism, even in the face of permanent exile.

Ephrem emerges as a more complex figure. He is not a cold enforcer but a man who preferred being an arborist, now trapped in a difficult job. The tears in his eyes and his tired, strained demeanor suggest he takes no pleasure in punishing Gaspery. His willingness to care for Gaspery’s cat hints at a residual humanity beneath his institutional role.

Aretta is revealed to be a competent operative, not merely a publicist. Her calm admission that she doesn’t go around telling people she’s a time traveler underscores her professionalism and contrasts with Gaspery’s more impulsive nature.

Zoey is a victim of Gaspery’s manipulation, though her brief appearance here—being restrained and escorted out—suggests she may face consequences of her own, though the chapter does not elaborate.

Themes, Symbols, or Motifs

The futility of altering the timeline is the central theme of this chapter. Gaspery’s intervention changes nothing meaningful: Edwin still dies of the flu, only slightly later and in a different location. Ephrem’s pointed question—“You see how pointless that was?”—forces the reader to consider whether any act of time travel can truly matter. Gaspery’s response, “You’re missing the point,” suggests that his goal was never to change the outcome but to offer Edwin a more dignified death. This raises a deeper question about the value of intention versus result.

Institutional enforcement is depicted through the armed guards, the formal sentencing, and Ephrem’s reluctant role as enforcer. The Time Institute operates as a bureaucratic machine that punishes deviation, yet its agents are not monolithic—Ephrem’s personal conflict humanizes the system.

Deception and betrayal run throughout the chapter. Gaspery deceived Zoey, Aretta deceived Gaspery, and the Institute itself operates on secrets. The web of lies highlights the moral compromises inherent in time travel.

Exile as punishment is introduced as the ultimate consequence. Gaspery is not imprisoned or executed but sent away permanently, a fate that echoes the novel’s broader concerns with displacement and belonging.

The 1918 flu pandemic serves as an inescapable historical force, indifferent to individual intervention. It underscores the limits of human agency against vast, impersonal events.

Escape fantasy vs. duty is embodied in Gaspery’s fleeting thought of staying in 1918. He imagines a simpler life, but his immediate action—entering the code—reveals that his sense of duty, however misguided, overrides his desire for escape.

Why This Chapter Matters

This chapter is a turning point in the novel. It resolves the immediate tension of Gaspery’s unauthorized mission but introduces the permanent consequence of exile. It also clarifies the nature of the Time Institute and its enforcement mechanisms, while deepening our understanding of Gaspery’s character. The revelation that Edwin’s death was inevitable regardless of Gaspery’s actions reinforces the novel’s meditation on fate and free will. Furthermore, the chapter sets up the next phase of Gaspery’s journey—one that will take him far from the moon and into the unknown. The emotional weight of Ephrem’s reluctant sentencing and Gaspery’s defiant acceptance makes this a memorable and pivotal moment in the narrative.

Study Questions and Answers

1. Why does Gaspery say “You’re missing the point” when Ephrem points out that Edwin would have died anyway?

Gaspery’s goal was never to prevent Edwin’s death but to save him from dying in an insane asylum. He believes that the manner of death matters—that dying in a place of despair is worse than dying in the world, even during a pandemic. For Gaspery, the point is not to change the timeline but to offer a person a measure of dignity in their final days.

2. How does Ephrem’s character complicate the idea of the Time Institute as a purely oppressive institution?

Ephrem is not a faceless enforcer. He is described as a man who preferred being an arborist, and he shows visible emotion—tears in his eyes, a tired and strained demeanor. He agrees to take care of Gaspery’s cat, a small act of kindness that suggests he retains compassion despite his role. This complexity makes the Institute’s enforcement feel more human and morally ambiguous.

3. What does Gaspery’s brief fantasy of staying in 1918 reveal about his state of mind?

The fantasy reveals a desire to escape the complications of his own time and the consequences of his actions. He imagines a simpler life, but he immediately dismisses it, indicating that he is not truly willing to abandon his identity or his responsibilities. It also highlights his awareness of the risks—he would be taking his chances with the flu pandemic—yet he still considers it, showing his deep ambivalence about returning to the Institute.
