Dalek Vibration Locator

Daleks in the control room monitor the vibration locator, which picks up tremors from Thal forces breaching the city walls. It records their advance inside the structure, emitting signals that alert other units and cut short the Doctor's TARDIS negotiation. Dalek 1 and Dalek 2 respond without pause, while Susan grows anxious and the Doctor presses his gambit amid rising peril.
