Reactor Chamber Catwalk

A narrow elevated metal walkway suspended above the reactor chamber floor, its industrial grating surface cold and unyielding underfoot. The structure trembles slightly as characters navigate it, amplifying the tension of the confined space during the interrogation. Peri stands with the Doctor and Jamie on the platform, her gaze flicking between them while the hypnotic fob watch hums nearby, its faint mechanical whine cutting through the palpable distress of the scene.
