Bunker Command Detonation Button

Davros hovers a taloned hand above the bunker’s security control console, using it as a podium for his monologues. The Doctor occasionally triggers the console’s beeps to mask the sound of his wiring, turning the failing system into a duet of hubris and subterfuge.

Davros’s hand hovers millimeters above the bunker security controls, using them as a prop to underscore his superiority while ignoring their actual function. The Doctor manipulates these same controls subtly to mask the sounds of his sabotage elsewhere.
