Mickey7 and Mickey8's Relationship

Mickey7 and Mickey8 are duplicate instances of Mickey Barnes whose relationship turns an abstract question about personal identity into an immediate fight over life and death. They share almost all their memories and experiences, yet neither can accept that the other is simply expendable. Their first response is to treat one another as a threat; their decisive turn comes when each recognizes the other as a distinct person who cannot be sacrificed without consequence.

A Shared Past, Unequal Presents

Mickey7 has spent years living under a system in which a dead Expendable can be replaced by a newly printed body carrying an uploaded set of memories. He describes this existence as a form of immortality, but one that is difficult to distinguish from repeated death: he remembers being earlier versions of himself, except for the final moments before their deaths. In one account, an earlier instance dies after a hull breach during transit, and the next awakens believing he is thirty-one, born on Midgard. Memory makes the succession feel continuous, but it cannot prove that the person who wakes is numerically the same person who died.

That uncertainty becomes intimate when Mickey7 returns to his room and finds another man asleep in his bed. The stranger wakes, sees Mickey7, and recognizes himself as Mickey8. The physical resemblance is not merely familial: both are versions of the same person, generated from the same backup. But the backup is not completely current. Mickey8 has the shared memories and experience up to the previous upload, while Mickey7 has lived the intervening six weeks. Mickey8 has existed for only minutes since leaving the tank, yet he is thirty-nine years old in memories and self-understanding, just like Mickey7. The small gap between them supplies the immediate argument: one has had more time in the present body, but neither has a wholly separate biography.

The Question of Who Must Die

The discovery instantly makes their continued existence dangerous. Mickey7 understands that if Command learns two instances are alive at once, the pair may both be sent to the corpse hole. He tells Mickey8 that one of them has to go. Their conflict is not a dispute that can be resolved through ordinary compromise: neither can take turns being the surviving person, and neither accepts the other's claim to priority. Mickey8 argues that he has been alive for only about twenty minutes while Mickey7 has had months; Mickey7 counters that Mickey8 is the same age in remembered experience and possesses almost all the same memories. Neither argument provides a neutral way to decide which life counts more.

They consider taking the matter to Command, but the prospect does not resolve the underlying problem. Instead, they face the possibility of choosing between themselves. Mickey7 has died six times in eight years, though some deaths were unexpected, one occurred in an emergency, and one earlier instance failed to upload. Those experiences make him familiar with the hollow anticipation of death, but not with this situation: ordinarily, the Expendable knows which instance is going to die. Here, each has an equal claim to survival and, in Mickey7's view, a fifty-fifty chance of being the one who dies.

The Corpse Hole and the Failed Decision

The corpse hole makes the threat physical. It is part of the colony's biological recycler, which breaks matter down into its component atoms and reconstitutes it as useful products. When Mickey7 opens the mechanism, its disassembler field appears as a flat black disk that quietly draws in dust motes in brief flashes. The opening is not an imagined execution but an operational means of disposal, and Mickey7 and Mickey8 stand before it knowing what a body put inside will become.

They settle on rock-paper-scissors as a way to choose. Mickey7 tries to anticipate Mickey8's thinking: because each knows the other's habits, he cycles through Rock, Paper, and Scissors until the countdown leaves him with a clenched fist. Mickey8 holds out a flat hand. Mickey7 has lost. He goes down on his hands and knees beside the hole and prepares to put his face near the interface, feeling the field tug at his skin. At that point, Mickey8 pulls him back and offers him a hand up. He cannot stand by and watch Mickey7 die, even though the game has just selected Mickey7 as the one to go. Mickey7 accepts the help. Their first meaningful agreement is not a solution to duplication but a refusal to let the other be killed by an arbitrary procedure.

A Precarious Practical Alliance

Once they abandon the immediate choice, the pair begin looking for a way to share a life under conditions designed for one instance. Mickey8 points out that they still have a heavy ration card, worth 2,000 kcal a day, and suggests splitting it so that both can remain alive for a while. The proposal is modest: it promises neither comfort nor a durable settlement, only time. But sharing food changes their relation from a contest for sole possession of Mickey Barnes's life into a practical negotiation between two people who must both eat.

Their work schedules pose a second problem. Mickey7 explains that only one of them can be out and about at a time if they are to avoid Marshall ordering both into the corpse hole. They consider dividing duty cycles, especially when a shift is assigned to Agriculture or Engineering. The arrangement might let them share the burden of ordinary work, but Mickey7 notes that it would not automatically protect them from a dangerous assignment such as cleaning the antimatter reaction chamber. Their cooperation therefore remains conditional: they can coordinate daily routines, yet they cannot control the authorities or guarantee that both will remain useful and undiscovered.

Identity Without Reassurance

The brothers' practical compromise does not reconcile their beliefs about what they are to each other. Mickey7 has considered whether each new instance is merely a successor who inherits a predecessor's memories. The answer he eventually gives Mickey8 is stark: shared memories do not make the two of them the same person. Mickey7 insists that his own life consists of the six weeks since the last upload, while Mickey8's life consists of the few days since his own creation. A future instance, should one be printed, would not continue either life from the inside; it would be another person sleeping in their bed and using their belongings.

That conclusion stands against Mickey7's earlier uncertainty about backup-based immortality. He can imagine that an awakened copy might be the original person looking through new eyes, and he acknowledges that friends and loved ones might not notice a difference. Yet he also suspects that, at some level beyond reason, he would know if his own consciousness had ended. Mickey8's presence makes that distinction impossible to leave as a thought experiment: both possess a powerful psychological connection to the same past, but each now has experiences the other does not. Their relationship holds together not because either can prove a shared, continuous self, but because each responds to the other's present vulnerability. The act of pulling Mickey7 away from the corpse hole gives that recognition practical force, even as the deeper question of whether either can survive through the other remains unresolved.
