The Doctor's Tracer Gadget

The Doctor's small, unassuming metallic device—referenced simply as a 'gadget'—matches Romana's earlier temporal tracer in both form and unreliable function. Its palm-sized case houses flickering irregular readings on a tiny screen, while a single protruding antenna whirs softly during operation. Though dismissed by the Doctor as minor, Romana's struggle to use it effectively suggests the instrument carries deeper temporal mechanics beyond its modest appearance.

Doctor confronts De Vries after ritual

The Doctor gestures with the tracer/gadget to emphasize his explanation, quickly downplaying its significance after Romana’s anxious query about detecting the Key to Time’s fragment at the circle.

Before: Operational in the Doctor’s hand, providing intermittent readings.

After: Still operational, though dismissed as merely a 'little gadget' by the Doctor immediately after Romana’s question.
