"This band is thicker than yesterday," he says.
"The band is identical. Your quad is stronger, which means the same resistance feels harder because you're generating more force against it. That's progress, Hewitt."
"Progress feels like punishment."
"Welcome to rehabilitation."
At the parallel bars, Okafor makes his way through the balance sequence with the concentrated focus of a man who does not trust his own feet. His hands grip the bars with more force than necessary, and the white of his knuckles tells me his confidence hasn't caught up with his capability.
He's steadier than he thinks. My job is to close the gap between what his body can do and what his brain believes.
Falk moves to station three and begins setting up for her own patient.
Her hands are quick and sure on the equipment panel. Her back is to Boone, and her position places her directly in Rivera's sightline through the observation glass.
"Falk." My voice carries the same professional tone it always carries. "Can you check the supply room inventory before your patient arrives? We're running low on resistance bands, and I want to make sure we have the full set for this afternoon's sessions."
The request is routine. I've made identical requests dozens of times over the course of her employment.
The difference is that the supply room is on the east wall, adjacent to the therapy pool's temperature control panel, and the request positions Falk away from the equipment stations and closer to Rivera's team in the administrative corridor.
"Sure." Falk crosses the treatment floor toward the supply room, and for a few seconds the operation feels clean and contained and exactly the way it was designed to proceed.
Then Falk stops.
She stops in the middle of the floor, between station three and the supply room, and her head turns toward the observation glass. The movement is subtle, a fractional rotation that would read as nothing to anyone who wasn't watching for it.
She's not looking at the glass. She's looking at the reflection in it, and the reflection contains an angle on the administrative corridor that she has never had reason to examine before today.
Whatever she sees in that reflection changes her posture.
The efficient aide disappears, and the person underneath surfaces in the set of her shoulders and the speed with which her hand drops to her side and finds her pocket.
My phone is in my scrub pocket. Boone mapped the emergency text protocol last night: one word, sent to Rivera's secure line, triggers the immediate approach.
Falk's hand comes out of her pocket holding a small remote.
Her thumb is on the button.
"Down," Boone says, and his voice fills the room with a calm authority that cuts through my pulse and every sound the equipment is making.
The word is quiet and controlled, the command of a man who has given orders in rooms where the consequence of being ignored is measured in bodies.
Falk presses the button.
The resistance station Hewitt is strapped into surges.
The load profile spikes from his prescribed setting to something far beyond the joint's tolerance, and the machine's hydraulic system drives his knee into extension with a force that tears a sound from his throat that I will carry for the rest of my career.
At the parallel bars, the floor-mounted balance platform Okafor is standing on destabilizes.
The platform's tilt calibration shifts violently, and Okafor's hands scrabble at the bars as his body pitches sideways,the spinal decompression patient whose balance is already compromised now fighting a surface that is actively trying to throw him.
In the therapy pool, the water temperature begins to climb.
The heating element override that Boone and I mapped last night is engaged, and the digital readout on the east wall panel ticks upward with the acceleration of a system that has been pre-programmed to overheat.
My body moves before the calculations finish.
