Thals commit to rescuing the Doctor

Though not directly manipulated in this segment, the Dalek Intrusion Fire Extinguisher’s presence in the spaceship interior is implied by Jo’s hiding and the subsequent traces of disturbance. Its repurposed form for probing and pressure-testing becomes a tangible sign of an unseen Dalek threat stalking the ship.

Before: Positioned near the spaceship’s compartment door, serving as a makeshift probe to test structural integrity under Dalek control.
After: The extinguisher’s activity leaves scratches and pressure marks on the TARDIS hatch, while its presence drives Jo to finally emerge and flee the compromised space.

Unseen entity stalks Jo in TARDIS

The Dalek intrusion fire extinguisher serves as an improvised probing tool for the unseen entity, tapping rhythmically against the TARDIS compartment door’s weak points. Its repurposed use heightens the threat level, turning a mundane device into an instrument of psychological terror. The extinguisher’s rusted metal leaves temporary marks on the door and indicates the entity’s measured, deliberate actions.

Before: Idle in the corridor, likely clipped to the unseen entity, showing signs of prior forced entries with scratches and clogged nozzle
After: Retained by the entity, now bearing additional residue from contact with the TARDIS door and jungle soil
