Objects Involved
Significant items in this scene
Sodium chloride is the critical medical remedy demanded by the Doctor to counteract Ian's poisoning from the aqueduct water. The First Elder, initially skeptical, agrees to provide it after the Doctor's urgent insistence. The Serving Sensorite retrieves it promptly, and the Doctor uses it to create a saltwater solution, which he administers to Ian. This object symbolizes the Doctor's scientific authority and the Sensorites' reluctant cooperation, as well as the immediate, life-saving measures required in the crisis.
Crystal water is identified by the Doctor as the safe hydration alternative to the contaminated aqueduct supply. The First Elder agrees to restrict all consumption to it, ensuring that no further poisoning occurs. While not directly administered to Ian in this event, its mention underscores the urgency of the crisis and the need for immediate action to prevent further harm. It represents the Sensorites' limited resources and the Doctor's pragmatic approach to mitigating the poisoning's spread.
Soft covers are draped over Ian as he lies incapacitated on the floor, providing comfort during his weakened state. The First Elder directs the Doctor and Susan to arrange them, easing Ian's physical discomfort amid the urgent diagnosis and treatment. While not a medical solution, these covers symbolize the Sensorites' limited hospitality and the Doctor's efforts to ensure Ian's dignity and comfort during the crisis.
The chemicals and equipment on the Doctor's ship are the key to synthesizing a proper antidote for Ian's poisoning and potentially curing the Sensorites' water supply. The Doctor insists on accessing them after administering the temporary saltwater solution, framing their retrieval as essential to resolving the crisis. This object represents the Doctor's scientific authority and the Sensorites' reliance on his expertise, as well as the next major conflict: securing the TARDIS lock to access the ship.
The Sensorite aqueduct water is identified by the Doctor as the source of Ian's poisoning, exposing the Sensorites' systemic negligence in maintaining their water supply. The Doctor points to it as the culprit after ruling out disease and contagion, and the First Elder confirms that victims die within three days of symptoms. This object represents the core conflict of the scene: the Sensorites' failure to address their infrastructure, which endangers both their people and the Earthlings. Its contamination drives the urgency of the Doctor's actions and the First Elder's reluctant cooperation.
Peach-flavored fruit served to the Doctor, Susan, and Ian in the reception room is ruled out as the source of Ian's poisoning after Susan observes that she and the Doctor consumed it without ill effects. This object serves as a red herring in the diagnosis process, highlighting the Doctor's methodical approach to eliminating potential causes. Its innocence is confirmed as the focus shifts to the aqueduct water, reinforcing the urgency of the crisis.
The TARDIS lock, held by the Sensorites, stranding the Doctor and his companions without access to their ship. The Doctor demands its return from the First Elder to fetch proper medication for Ian's poisoning, setting up a critical negotiation. The lock symbolizes the Sensorites' control over the Earthlings' fate and the Doctor's desperation to regain autonomy. Its return is contingent on the Second Elder's approval, highlighting the bureaucratic hurdles the Doctor must overcome to save Ian and the Sensorites.
