Master revives the Doctor’s stalled heart

The Master’s stethoscope becomes a tool of both diagnosis and desperation. He uses it to confirm the Doctor’s single heartbeat, a moment that reveals the severity of his condition. The stethoscope’s cold metal diaphragm pressed to the Doctor’s chest is a stark contrast to the Master’s usual disdain for physical intervention—here, it symbolizes his reluctant acknowledgment of the Doctor’s fragility. Its role is functional (diagnosing the stalled heart) but also narrative (highlighting the Master’s rare moment of vulnerability).

Before: Lying nearby in the Processing Theatre, unused but accessible.

After: Still in the Master’s hand after confirming the Doctor’s condition, later discarded as he shifts to manual revival.
