S22E1 · Attack of the Cybermen Part 1

Doctor and Peri unpack TARDIS arrival

Halley’s Comet appears on the scanner as a luminous marker in the void, visually confirming their solar system location to Peri. Its familiar trajectory contrasts with her expectation, becoming a narrative pivot that grounds the TARDIS in recognizable celestial geography.

Before: Comet was present in Earth’s sky but visually irrelevant to the TARDIS crew until the scanner’s activation.

After: Comet remains a static celestial marker, now carrying narrative significance as a coordinate clue.

S22E1 · Attack of the Cybermen Part 1

Doctor pinpoints Halley's Comet and 1985 Earth

Halley’s Comet appears as a bright white blob with a luminous tail on the scanner screen, serving as an instant navigational landmark. Its familiar appearance to Peri provides a touchstone of Earth-normality in an otherwise disrupted journey, subtly reinforcing the Doctor’s long-range temporal aim despite the rough ride. The comet becomes a visual pivot between cosmic disarray and human proximity.

Before: A distant, fast-moving celestial body in Earth’s solar system; visually unremarkable from the TARDIS exterior

After: Projected as a clear, recognizable object on the scanner interface, confirming their spatial identity and temporal target

S22E2 · Attack of the Cybermen Part 2

Doctor learns Cybermen comet plot details

Halley’s Comet is reframed as a kinetic and temporal weapon the Cybermen intend to divert from its orbit into Earth, threatening both planetary annihilation and timeline rupture. The Doctor treats its trajectory as a systemic violation, broadening the conflict from a local coup to a cosmological emergency.

Before: In normal solar orbit, viewed as a celestial object with predictable cycles

After: Identified as a premeditated armature of mass destruction and temporal sabotage central to the Cybermen’s grand design
