Summary

The chapter opens with Andrew tearing the sheets off Lily, waking her abruptly. He is freshly showered, bright-eyed, and manic, handing her a coffee in a mug she won months ago but never used. He announces he has been thinking all night about legacy and wants to build a monument so future residents will remember them. He also suggests they pretend to be a couple to impress the producers. Lily, still groggy and unsettled by his intensity, reluctantly agrees.

Andrew proposes a division of labor: he will build the monument outside while Lily cleans the house and cooks. When she protests that she is not much of a cook, he insists she and Carlos used to make wonderful meals—but Lily corrects him: that was Candice and Carlos. She only cleaned. Andrew brushes this off, saying he has faith in her.

He then asks her a series of probing questions about what she wants from life and why the two of them have made it this far. Lily reflects that she is there because she thought it was what she was supposed to want, while Andrew is there because he needs control and fears loneliness. Andrew argues that making it to the last two is a worthier achievement than winning, and that they should work together. He tells her he has always had a soft spot for her, and suggests the producers must want them to be together. Lily bluntly says she wants Sam, not him. Andrew admits he does not particularly want her either, but thinks they should give the audience what they want. He promises it would all be pretend. Lily, worn down, agrees.

In the days that follow, Andrew works obsessively outside on his monument—which turns out to be an immense pile of rubbish and broken objects. Lily cleans the house and receives lavish rewards: designer furniture, a Murano glass chandelier, an LED face mask, cashmere, cosmetics. She notices Andrew has become strange since his illness: erratic moods, little sleep, talking to himself, snapping at messes and then apologizing nervously.

Their evenings are spent in awkward, forced togetherness. Andrew holds her hand and talks at length about how well the production team cared for him when he was sick. Lily asks if he thinks Sam would want to see her on the outside, and whether Candice would want to see him. Andrew says no—he chose the show over Candice, and he does not expect her to want him back. He declares they will stay for six months or a year, longer than anyone has.

The screen in the living room displays a new task: Kiss the other resident. The reward is a key, though what it unlocks is unknown. They never discuss the screen, though it looms over them.

One night Andrew does not come to bed. Lily finds him at the northern perimeter, torch in hand, staring out over the desert. He tells her he has realized how close the production team is—there are vents connecting the compound to them, just beyond the sand. He seems almost wistful about getting sick again, because they would come and look after him. Lily persuades him to come inside, but when they reach the house, the door is locked. They have been locked out.

Andrew runs off toward the perimeter, searching for the production team, but finds nothing. Lily sits on the step, shivering, reflecting that this feels like punishment for what she did to Tom. Andrew returns and insists neither of them is going anywhere. Then he handcuffs Lily to a pipe using the jewel-encrusted handcuffs she won as a reward. He tells her he is not going to kiss her—he does not want to get rid of her—he just needs to make sure she does not leave.

Andrew then bashes his head against the wall, blood gushing from his forehead, his nose displaced. He tells Lily she needs to injure herself too, so the production team will come and take care of both of them. He picks up a rock and offers it to her. Lily screams, and the sound frightens him; he drops the rock and insists he is not like Tom, he is nice. He curls behind her on the cold ground, his blood seeping into her shirt, and asks if she will pretend to be Candice while he strokes her hair. Lily cries and pulls at the handcuff.

Lily eventually drifts into sleep. At dawn she wakes to find Andrew pale and caked in blood. He realizes the production team never came. The knowledge that no one cares about him settles over him. He unlocks the handcuffs, takes her face in his hands, and asks for a kiss. Lily kisses him, tasting his blood, and a voice announces: Andrew, you are banished.

Andrew tells her to get the key from the delivery area and go inside. He asks her to bring his things when she eventually leaves, and says he will meet her at the meeting place. Lily hugs him tightly, begging him not to go, suddenly unable to face being completely alone. He tells her she will not be alone—they will all be watching her at home. He walks away into the desert until he is indistinguishable from shadow. Lily stays sitting on the step, waiting for someone else to arrive.

Character Development

Andrew reaches his most extreme state in this chapter. His earlier need for control and fear of loneliness curdle into something desperate and delusional. He genuinely believes the production team will rescue him if he injures himself, and the moment of dawn—when he realizes no one came—is a quiet devastation. His final speech, admitting he does not really know what he is doing and is not very happy, is the most honest he has been. He leaves not with triumph but with a kind of hollow, performative cheerfulness.

Lily spends the chapter oscillating between compliance and resistance. She agrees to the fake relationship and the cleaning because it is easier than confronting Andrew, but she refuses to injure herself and screams when he approaches with the rock. Her final plea—I don't want you to go—reveals her terror of being alone, even after everything Andrew has done. She has spent the whole book trying to survive, and now that survival means solitude, she is not sure she wants it.

Themes, Symbols, or Motifs

Performance of happiness: The fake relationship is a performance for the audience, but it also becomes a performance Andrew forces on himself. He talks about how wonderful everything is while his behavior grows more erratic.

The monument: Andrew's pile of rubbish is a symbol of his delusion—he believes he is building something meaningful, but it is literally garbage. It mirrors his own sense of self-worth, which collapses when the production team ignores him.

Surveillance and control: The vents Andrew mentions reveal the compound as a stage with the production team just beyond the sand. The screen, the tasks, the rewards, and the lockout all demonstrate how the residents are controlled by unseen forces.

The key: The promised reward for the kiss task is a key, which becomes literal when Andrew tells Lily to retrieve it. It represents both freedom and the burden of being alone.

The cold: The bitter night cold is a physical manifestation of the emotional isolation both characters feel. Andrew's blood freezing on the ground is a stark image of his abandonment.

Why This Chapter Matters

This chapter is the climax of Andrew's arc and a turning point for Lily. Andrew's banishment removes the last other resident, leaving Lily completely alone in the compound—the situation she has been working toward all along, but which she now realizes she does not want. The chapter also confirms the production team's cruelty: they lock the residents out, dangle a key as a reward, and let Andrew injure himself without intervention. The compound is not a home; it is a prison with an audience.

Study Questions and Answers

1. Why does Andrew build a monument, and what does it reveal about his character?

Andrew builds the monument to create a legacy and impress the producers, but it is actually a pile of rubbish. This reveals his desperate need for validation and his inability to see himself clearly. He believes he is contributing something meaningful, but he has not actually fixed or improved anything. The monument is a physical symbol of his delusion.

2. How does Lily's behavior in this chapter show both compliance and resistance?

Lily complies with Andrew's plans—she agrees to the fake relationship, cleans the house, and listens to his long monologues—because it is easier than confrontation. But she resists when it matters: she refuses to injure herself, screams when he approaches with the rock, and pulls desperately at the handcuffs. Her compliance is survival strategy; her resistance is self-preservation.

3. What does Andrew's banishment mean for Lily, and why is she not relieved?

Andrew's banishment means Lily is now completely alone in the compound, which is what she has been working toward. But she is not relieved because she is terrified of solitude. She begs him not to go and hugs him tightly, realizing that even a dangerous companion is better than no companion at all. The chapter ends with her sitting on the step, waiting for someone who will not come.
