Zero Cabinet exposes master plan

Tegan and Nyssa uncover the Zero Cabinet repurposed as a washtub, stripping away Shardovan’s facade of neutrality. Tegan’s accusation unlocks the truth—that far more than the Doctor is trapped in Castrovalva—while Ruther’s cryptic interjection suggests the town’s residents are active conspirators. The companions flee with the evidence, realizing Castrovalva’s fragile order is built on a lie that now threatens to collapse entirely on the Master’s command. key_dialogue: [ TEGAN: You hid this deliberately. SHARDOVAN: Assuredly, ma'am, no impropriety was intended. TEGAN: You're all part of this. It's a conspiracy. RUTHER: They have formed the suspicion that the Doctor has been ensnared. SHARDOVAN: Ah. They cannot think that. ]
