2 moments
S1E36 · A Desperate Venture
Susan and Barbara challenge the Elder

The Warrior-provided Sensorite weapons are mentioned as part of the useless gear given to the Doctor and Ian. Barbara reveals their inefficacy (‘the maps and the guns given to the Doctor and Ian are quite useless’), framing them as part of the Sensorites’ betrayal. Their mention serves as a catalyst for the confrontation, as the companions use the weapons’ failure to demand better resources. The guns symbolize the Sensorites’ half-measures—offering tools of defense while withholding true aid. Their uselessness becomes a metaphor for Sensorite hypocrisy.

Before: In the possession of the Doctor and Ian (given by the Warrior earlier in the scene), but revealed to be ineffective in the aqueducts.
After: Exposed as part of the Sensorites’ deception. Their failure to protect the Doctor and Ian is used to justify the demand for an authentic map.

S1E36 · A Desperate Venture
Barbara forces the Elder’s decisive turn

The First Elder’s ‘good aqueduct map’ is the pivotal object in this event, symbolizing the Sensorites’ shift from obstruction to cooperation. Though not yet physically handed over, its existence is confirmed by the First Elder in response to Barbara’s demand. The map represents not just a tool for navigation but a metaphorical bridge between the Sensorites and the companions, signaling the former’s willingness to trust and aid the latter in their hour of need.

Before: Stored securely within Sensorite archives, its accuracy and reliability contrast with the earlier deceptive maps provided to the Doctor and Ian.
After: Its promise of provision sets the stage for the rescue mission, though its physical handover and use will occur in subsequent scenes.
