Summary

The chapter opens with Mickey and Nasha walking back to the dome in silence after discovering the bomb is missing from its hiding place. Nasha breaks the silence to remind Mickey that she warned him two years ago that burying a doomsday weapon under rocks was a terrible idea. Mickey acknowledges that they both knew it was a bad plan, but neither had a better option at the time.

As they walk, they debate whether Marshall could be responsible for the bomb's disappearance. Nasha wonders if Marshall has been manipulating Mickey all along, possibly to build a case against him as a traitor to the colony. Mickey recalls that Marshall recently asked him to return the fuel from his bomb to the reactor, which complicates the picture. Nasha also brings up the two copies of Mickey that Marshall pulled from the tank in the past week, noting that Quinn Brock confirmed the duplication.

Back in Mickey's quarters, Berto joins the discussion. He immediately dismisses the idea that Marshall has the bomb, arguing with cold logic: if Marshall possessed it, he would have ordered Mickey to return the fuel elements to the reactor, and if Mickey refused, Marshall would have recycled him and pulled a fresh copy from the tank to do the job. Marshall is a practical administrator focused on colony survival, not a scheming villain who would waste time on mind games. The fact that Mickey is still alive, Berto insists, is proof that Marshall doesn't have the bomb.

Nasha pushes back, mentioning the two copies pulled from the tank, but Berto remains unconvinced. He points out that even if Marshall used those copies to deal with reactor damage, there would be no reason to keep the original Mickey alive. The group then considers whether another colonist could have found the bomb, but Nasha dismisses this: anyone who found it would either turn it over to Marshall or accidentally detonate it. That leaves only one possibility. Berto grins and points out that Mickey has been telling Marshall for two years that the creepers have the bomb—and now it appears they actually do.

Meanwhile, Mickey receives a series of messages from a previous version of himself, urgently requesting to talk. The messages grow more desperate, ending with a plea that they need to communicate.

Marshall summons Mickey and orders him to negotiate with the creepers face-to-face, insisting that negotiations of this magnitude are best concluded in person. Mickey begins packing for an expedition into the labyrinth, loading a pack with food, water, and survival gear. Nasha appears and announces she's coming with him. Mickey protests, but Nasha points out that he hasn't uploaded in over two years—he's no longer an Expendable. She tells him he doesn't have to die for her anymore, and she won't let him. When he continues to object, she threatens to break both his legs so neither of them goes.

The two set out across the frozen landscape. The temperature has dropped significantly, and the sun is barely visible behind clouds. Mickey carries twenty kilos of supplies; Nasha carries an arsenal of burners and a linear accelerator. Along the way, Nasha asks about the plan. Mickey admits he has only an outline: go into the labyrinth, find a creeper, ask for the bomb back. Nasha teases him about drifting through life like a jellyfish, and Mickey acknowledges that his improvisational approach has gotten him killed multiple times—but it also led him to her.

They reach the entrance to the labyrinth, which is smaller than Mickey remembers. Nasha insists on going first, arguing that the muscle goes before the diplomat. She draws her burner and descends into the hole, leaving Mickey to follow.

Character Development

Mickey confronts the consequences of his past decisions in this chapter. His choice to bury the bomb two years ago—a decision he knew was flawed—has come back to threaten the entire colony. He also faces a significant identity shift: for the first time, he fully registers that he hasn't uploaded in over two years and is no longer Expendable. When Nasha reminds him of this, he admits he had forgotten. His characteristic improvisational approach to life is on full display when Nasha asks for the plan and he admits he doesn't have one beyond finding a creeper and asking for the bomb back.

Nasha emerges as fiercely protective and committed. She reminds Mickey that she was in on the bomb's hiding from the start, and her motivation was simply to keep him alive. She refuses to let him face the creepers alone, threatening physical harm if he tries to leave her behind. Her statement that Mickey no longer has to die for her marks a turning point in how she sees him.

Berto provides the logical counterweight to Mickey's improvisation. His argument about Marshall's practical nature is persuasive and ultimately convinces the group that the creepers must have the bomb. He also delivers the ironic observation that Mickey's long-standing lie to Marshall has become true.

Themes, Symbols, or Motifs

Consequences of past actions. The bomb's disappearance is a direct result of Mickey's decision to bury it two years ago. Nasha's reminder that she warned him at the time underscores how past choices ripple forward.

Sacrifice and loyalty. Nasha's insistence on accompanying Mickey into the labyrinth, despite the danger, demonstrates her willingness to risk her life for him. Her statement that he no longer has to die for her reframes their relationship.

Expendable identity. Mickey's realization that he hasn't uploaded in over two years means he is no longer replaceable. This changes the stakes of the mission: if he dies now, he stays dead.

Improvisation vs. planning. Nasha's question about the plan highlights Mickey's jellyfish-like approach to life. His admission that drifting got him onto the expedition and killed him multiple times—but also led him to Nasha—captures the tension between these approaches.

Alien communication. The chapter sets up the central challenge of negotiating with the creepers. Mickey's uncertainty about whether he can still communicate with them adds tension to the mission.

Why This Chapter Matters

This chapter is the pivot point between the mystery of the missing bomb and the direct confrontation with the creepers. It resolves the question of who took the bomb through Berto's logical reasoning, then immediately raises the stakes by sending Mickey into the labyrinth. The chapter also solidifies Mickey's transformation from Expendable to ordinary human, making his potential death in the labyrinth genuinely permanent. Nasha's decision to accompany him deepens their relationship and raises the emotional stakes of the mission. Finally, the messages from a previous version of Mickey introduce a new mystery that will presumably be explored in the coming chapters.

Study Questions

1. Why does Berto conclude that Marshall cannot have the bomb?

Berto argues that Marshall is a practical administrator focused on colony survival. If Marshall had the bomb, he would have ordered Mickey to return the fuel elements to the reactor. If Mickey refused, Marshall would have recycled him and pulled a fresh copy from the tank to complete the task. Marshall would not waste time on psychological games. Therefore, Mickey being alive proves Marshall doesn't have the bomb.

2. What does Nasha mean when she tells Mickey he is no longer an Expendable?

Nasha points out that Mickey hasn't uploaded in over two years. Even if Marshall pulls another copy of Mickey from the tank after his death, that copy won't be the same person. Mickey is now just Mickey Barnes, an ordinary colonist whose death would be permanent. This changes the stakes of the mission and is why Nasha refuses to let him go alone.

3. How does Mickey's improvisational approach to life both help and hurt him?

Mickey admits he drifts through life hoping things work out. This approach got him onto the expedition in the first place and has resulted in multiple deaths from various causes. However, it also led him to Nasha, whom he considers worth all the suffering. In this chapter, his lack of a detailed plan for negotiating with the creepers is a liability, but his willingness to improvise may be exactly what the situation requires.
