Doctor's Sonic Screwdriver (Auton Deactivation Mode)

The thin insulated cable connects the Doctor’s sonic device to the reflecting dish, channeling the amplified sonic waves that overload Scobie 2’s Auton circuits. Without this cable, the device would be unable to transmit the signal effectively. The cable is a critical component in the Doctor’s improvised solution, enabling the exposure of the Nestene infiltration and the restoration of UNIT’s command structure.

Before: Attached to the sonic device and ready for use. The cable is in good condition and fully functional.
After: Still attached to the sonic device but may require recharging or maintenance after the high-energy transmission. Its role in the event is complete, but it remains a vital tool for future countermeasures.
Doctor’s Handheld Microphone (Factory Yard)

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.
