Answer Key

Plot and Sequence

B — At a family dinner party, Edwin speaks against British colonialism, and his father sends him to Canada a week later instead of the following year.

C — The ship's manifest records his occupation as “farmer,” despite his never having handled a spade.

B — Edwin experiences the anomaly in the forest near Caiette, where he sees the priest Roberts and later finds himself in a vast interior space with violin music.

The video contains a brief anomaly—a black screen with overlapping sounds. Mirella also learns of Vincent's death at the concert.

B — Colony Two's dome lighting failed within a century, ending the simulated Earth sky and the twenty-four-hour day, so it became known as the Night City.

B — Zoey shows Gaspery a projection of the concert video, a passage from Olive Llewellyn's Marienbad, and a 1912 letter from Edwin describing a similar experience.

B — Aretta reads an updated bio stating that Edwin died in the 1918 flu pandemic thirty-five days after Gaspery's visit.

Gaspery wakes under a twentieth-century overpass in Ohio, where he sees two schoolgirls—one of whom he recognizes as a young Mirella—and is framed for a shooting.

Character Motivation

B — Mirella's husband Faisal invested in Jonathan Alkaitis's Ponzi scheme and killed himself after its collapse.

  1. B — Gaspery is restless and impatient with his life; he tells Ephrem he wants to begin training immediately.

  2. B — Gaspery reflects in prison that warning Olive was not wrong: “If someone's about to drown, you have a duty to pull them from the water.”

  3. B — Edwin believes that counting his paces will calm him and that walking straight will prevent him from getting lost.

  4. Talia warns that the Time Institute only corrects time-travel damage that affects itself and will discard him once he is no longer useful.

Theme and Symbol

  1. B — The lullaby, composed by Alan Sami for his late wife, is heard by Edwin, Vincent, and Gaspery during the anomaly, connecting them across centuries.

  2. B — The phrase, scratched on a prison wall by Gaspery, echoes the novel's meditation on impermanence, from the death of stars to the end of the world.

  3. C — Gaspery concludes that even if the world is a simulation, the appropriate response is indifference, because a life lived in a simulation is still a life.

  4. The forest represents a liminal threshold and a place of both threat and revelation. Edwin normally avoids it out of fear of bears and cougars, but it is where he encounters the priest and the anomaly.

Synthesis

  1. C — Mirella sees the video of the anomaly but does not experience it directly. Edwin, Vincent, and Gaspery all witness it firsthand.

  2. The novel connects the timelines through the anomaly itself—a moment of darkness, violin music, and a vast interior space that bleeds across centuries. The violin lullaby, the forest video, and the letter from Edwin all describe the same event.

  3. It reveals that time is not linear but can be corrupted and repaired, and that the anomaly was caused by Gaspery's own time-traveling presence. The older Gaspery realizes he caused the very anomalies he was sent to investigate.
