Patrick's Dimension Scanner

The TARDIS scanner's amber display flickers with jagged energy spikes as the Doctor holds it, its matte-black casing slick with condensation. Once a reliable device for short-range analysis, it now quivers in his grip as the image of Skaro fills the display—a ruinous planet lit by distant solar flares. Jo's fingers tighten around the control dial, shifting the view from war’s scars to Earth’s blue horizon, her silent correction marking the first time she overrides its function.

Purpose

To detect and display electromagnetic anomalies and trans-dimensional disturbances by sampling ionic residues and mapping spatial fluctuations for real-time visualization.

Significance

Serves as the pivotal device through which Jo confronts the Doctor about her wish to return home, transforming from a neutral instrument into a symbolic battlefield over their partnership’s future.

S10E3 · The Three Doctors Part 3

Team discovers alien world invasion of UNIT lab

Patrick’s dimension scanner is brought into the lab to investigate residual antimatter traces, contributing to the unstable atmosphere but failing to provide coherence amid the Gel’s dimensional shift.

Before: Portable, operational device clipped to Patrick’s belt

After: Activated but erratic; screen displays alien energy spikes beyond calibration

S10E3 · The Three Doctors Part 3

Brigadier reconnoiters alien shoreline alone

Patrick keeps this device clipped to his belt throughout the lab scene. Its compact sensor array scans the anomalous residue left by the Gel’s dimensional shift, producing erratic energy spikes on its flickering amber display that baffle human instrumentation. Its whine adds a layer of tension as the lab’s physics fray.

Before: Portable, fully operational handheld scanner used for routine antimatter residue detection.

After: Continues to hum erratically, its output now nonsensical within known physics paradigms.

S10E20 · Planet of the Daleks Part 6

Doctor and Jo discuss going home

The scanner serves as the focal device through which the Doctor presents Skaro’s devastation and Jo enacts her decisive counter-move. Its amber display flickers with jagged energy spikes as Jo’s fingers tighten around the control dial, physically shifting the image from war to Earth. It becomes the tangible medium for their opposing visions of path and purpose.

Before: Displaying an image of Skaro’s ruined surface, likely flickering with distress patterns under the Doctor’s manipulation. Held firmly by the Doctor.

After: Showing Earth’s blue horizon after Jo overrides the Doctor’s view and asserts her own destination.
