As Mayor Jahns and Deputy Marnes climb back toward the upper levels during the power holiday, the return journey feels far harder than the descent. Jahns is exhausted by the stairs and by the dim emergency lighting, and the quiet silo makes her newly aware of its divisions: the upper levels live by the view outside, the middle levels by food and daily trade, and the deep levels by machinery and labor. That realization unsettles Jahns, because it makes her question the importance of her own office and suggests the silo depends more on its workers than on its leaders.

That night, the pair stay at a mid-level deputy station. Lying awake in the dark, Jahns reflects on the conversations she and Marnes have shared during the climb, on her dead husband Donald, and on the lonely life she has justified as public service. She also admits to herself that part of her desire to go deep and recruit Juliette was an attempt to escape the grief Holston and Allison have stirred in her; instead, the journey has only sharpened her understanding of why some people might choose death over emptiness.

When someone enters her room in the dark, Jahns realizes it is Marnes. Without speaking much, they let their long-suppressed affection become physical and tender. Jahns cries from fear, grief, and relief, then feels unexpectedly alive and comforted. They fall asleep together, and Jahns wakes to an empty bed but a fuller heart, changed by the intimacy they finally allowed themselves.

On the fourth and final day of climbing, Jahns delays their arrival at IT because she dreads seeing Bernard and the end of the journey with Marnes. The power holiday has left most of the silo in brownout conditions, but IT remains brightly lit because Bernard has secured power exemptions under the Pact, a political compromise Juliette resents and Jahns considers necessary. The contrast between IT's comfort and the rest of the silo's deprivation sharpens the tension before Jahns even steps inside.

At IT, Bernard is waiting and immediately turns the meeting hostile. He accuses Jahns of using the power holiday to hurt him, while Jahns insists IT already has its full allocation and tries to complete Juliette's appointment papers. Bernard rejects Juliette as "this girl from the pits," but Marnes cuts in and says Juliette already has the job. After Bernard refuses to sign and taunts Jahns about whether she will outlive yet another sheriff, he orders the young technician Lukas to sign, copy, and process the paperwork instead, effectively allowing Juliette's appointment while making his opposition unmistakable.
