Object
Large Red Knob on Davros' Torture Benches
A prominent large red knob protrudes from the control panel of the torture benches in Davros's bunker interrogation room. Davros grips and turns it to activate wired devices that convulse Sarah and Harry in agony while the Doctor watches in torment. Nyder stands guard. Davros later directs it at the Doctor, cranking up the pain until the Time Lord breaks and reveals future Dalek defeats. Davros then turns the knob down, halting the torment and freeing the companions.
