Doctor reels as Bessie vanishes and beast closes in

The Doctor’s worst suspicions are confirmed when Bessie vanishes after he and Jo barely escape the laboratory explosion, leaving the Brigadier scrambling to process multiple disappearances. Discovering a new X-ray plate showing Earth scanned by an unidentified beam, the Doctor deduces the antimatter entity has targeted him directly and is now moving through UNIT’s infrastructure via the drains. The scene pivots from academic investigation to desperate mobilization as the Doctor warns the Brigadier they cannot hunt the creature—it will hunt them instead. With local man Ollis gone and Tyler vanished without trace, the threat’s scale crystallizes: not merely a hazard to contain, but a hunter with a single-minded focus on the Doctor. The reveal stings because every precaution has been rendered moot; the entity’s presence has become inescapable.

Sondergaard's Geiger Counter

The Doctor uses a Geiger counter to scan the open evidence box and the sink’s plug hole, detecting anomalous radiation spikes that confirm the antimatter entity’s infiltration through UNIT’s infrastructure. The device’s erratic behavior underscores the presence of something beyond human science—a tool detecting what should not exist.

Before: Operational and in the Doctor’s possession
After: Still functional but yielding readings that unsettle even the experienced scientist
UNIT Laboratory Floor Drains (Emergency Evacuation System)

The industrial drains in the UNIT lab are identified by the Doctor as primary infiltration routes for the antimatter entity. His urgent directive to post guards on them reflects the realization that the entity exploits utility infrastructure to hunt its target, turning mundane building systems into conduits of existential peril.

UNIT Staff Car 'Bessie' (Super Drive Variant)

Bessie, the Doctor’s antimatter-based vehicle, vanishes after the Doctor and Jo barely escape a kinetic surge in the garage. Her sudden disappearance is the first direct sign that the entity has penetrated UNIT’s perimeter and is explicitly targeting the Doctor, transforming a personal mode of transport into tangible proof of an inescapable hunter.

Tyler's Cosmic Ray Evidence Container

The open evidence box that once contained Tyler’s developing plate becomes a focal point during the scene. Beneath the Doctor’s Geiger counter, its contents and the nearby plug hole reveal the entity’s physical presence, its residue glowing faintly. The box’s contents—Tyler’s last work—are crucial to understanding the entity’s arrival vector.

Tyler's X-Ray Plates

Tyler’s newly developed X-ray plate shows Earth scanned by an unidentified energetic beam. The Doctor presents this image to the Brigadier and Jo as definitive proof that the antimatter entity arrived via an external scanning mechanism, directly connecting Tyler’s scientific work to the entity’s interdimensional ingress and Tyler’s own vanishing.

UNIT Daily Reports

Satellite surveillance teleprinter reports show global energy spikes corresponding to the entity’s beam scanning Earth. These documents, brought by the Brigadier, become the geographic and temporal map of the attack, validating Tyler’s hypothesis and anchoring the crisis in verifiable science even as the entity’s physical existence defies containment.
