Doctor exposes Scobie 2 as Auton

The Doctor attempts to use a microphone to force Scobie 2 to speak, which would reveal his Auton nature. However, Scobie 2 scoffs at the request and collapses before complying. The microphone serves as a secondary tool in the Doctor’s effort to expose the impostor, though it is ultimately unnecessary once the sonic device is activated. Its role highlights the Doctor’s willingness to use multiple methods to uncover the truth.

Before: In the Doctor’s hand, ready for use. The microphone is functional and part of the Doctor’s improvised toolkit.
After: Unused in the final exposure of Scobie 2, but remains a potential tool for future investigations. The Doctor’s focus shifts to the sonic device as the primary method of revelation.
