Doctor’s Microphone (Decontamination Unit)

The Doctor’s microphone in the decontamination unit serves as the final, ironic conduit for dialogue before the betrayal. His words—‘Right, I'm ready when you are’—are spoken into it, signaling his trust in the process, while Cornish’s unwitting response provides the false sense of security. The microphone’s role is twofold: functional (enabling communication between the Doctor and Cornish) and narrative (highlighting the contrast between the Doctor’s compliance and the impending violence). Its use in this moment underscores the fragility of trust and the ease with which institutional betrayal can occur under the guise of routine.
