The Tuberculosis Pavilion is a former hospital building whose architecture carries successive forms of institutional confinement. Once the largest and best-equipped structure in the complex, it contained enough beds for three hundred patients at its peak. Under Cal’s authority, most of it remains off limits, while its old seclusion rooms become a makeshift prison. The building’s history is not left behind: the rooms’ cages and locks, installed for earlier institutional purposes, are still used to confine people.

Building and institutional history

The pavilion is a four-story red-brick structure that once served as an infectious-disease hospital. Its seclusion rooms retained their original confinement equipment during the years the site was used for juvenile addicts, and Cal’s community later used those rooms as a prison. The building’s former scale and equipment distinguish it from the rest of the complex, but its role has narrowed: the seclusion rooms are the only part of the pavilion put to use.

That continuity matters to the building’s function in the story. The rooms are not improvised from nothing; a previous institution’s means of isolation remain available for a new authority to use. The pavilion therefore holds both the memory of its medical purpose and the practical mechanisms of confinement. Its history appears in the physical arrangements rather than in an account of its former occupants.

Restricted space under Cal

Cal declares the pavilion out of bounds to members of her community. The restriction is reinforced by makeshift barriers built from tattered furniture and rubble, intended to keep children out and difficult for young children to climb over. The boundary is thus both an order and a physical obstruction. The site’s separation from ordinary community life helps make the pavilion a place where confinement can occur beyond the spaces children are meant to occupy.

Cal brings Apollo Kagwa and William Wheeler there with her guards. At the entrance, one of the twins pulls away boards fixed across the doorway while the other stands behind the prisoners with mace ready. The guards also have William’s phone. Cal asks about what William was doing when he was found, placing the pavilion within an inquiry as well as a punishment. Its function is not simply to hold the two men: it is where Cal can keep them apart from the community while questioning them.

The seclusion rooms

The rooms are mesh cages secured by dead bolts. Apollo and William are locked in adjacent cells: they can see and speak to one another, but the tightly woven mesh prevents them from reaching through. Their arrangement allows conversation while preserving the barrier between them. Even beside one another, they remain physically separated.

The rooms’ windows have long been smashed, and mesh wiring across the frames prevents escape. Moonlight enters, but the openings do not offer a way out. William sits with his back to the cage door and notes that he has his glasses again; the small detail establishes that personal belongings accompany him into this stripped-down, controlled setting. Later, Cal returns just after dawn with the twin guards. William puts on his glasses as she enters Apollo’s cage, and the side-by-side cells again make their confinement visible as a shared condition that does not remove the barrier between them.

Apollo’s return and the pavilion’s significance

The pavilion reappears when Apollo comes to its outer wall at night, after leaving a gathering where Cal is present. He skirts the building, looking for the window of William’s room. Finding a rock about the size of a softball, he steps back five paces and throws it, shattering the window. The mesh remains between Apollo and William’s cell. Apollo hears no response and cannot tell whether William is still there or has already been taken away.

The act changes Apollo’s relation to the pavilion without undoing its purpose. Earlier he was brought inside and locked into one of its cages; now he approaches from outside and breaks the window, but the barrier that defines the room remains. The damaged opening offers no confirmation, rescue, or direct contact. Across both episodes, the pavilion turns institutional architecture into an active force in the plot: it confines Apollo and William, limits what they can know about one another, and makes even an attempt to reach across the divide stop at the mesh.
