Nyssa reveals ultrasonic threat in cavern

The team begins to celebrate their victory over the androids when Nyssa examines the destroyed machine and realizes its primitive design. She discovers that the android was not merely a combatant but a sophisticated ultrasonic transmitter, one that likely signaled their presence to distant enemies. The Doctor swiftly shifts the group's focus from triumph to survival, ordering the immediate securing of the cavern's hatch. Scott questions the urgency but quickly accepts the need for caution as the implications of the android's true purpose sink in. This moment shatters their fleeting relief with a stark warning that unseen enemies may already be converging on their location. key_dialogue: [ NYSSA: It's very primitive. DOCTOR: You think so? NYSSA: Look at this. DOCTOR: Lieutenant? SCOTT: Yes, Doctor? DOCTOR: I think you should curtail the celebrations for the time being. SCOTT: Oh, something wrong? NYSSA: One of the androids was a massive ultrasonic transmitter. ADRIC: So that was the signal I picked up in the Tardis. SCOTT: What does that mean? DOCTOR: Whoever built this hatch now knows we've destroyed its guardians. ]

Doctor's TARDIS

The TARDIS serves as the team's primary objective reference point, its systems having detected the mysterious signal that Adric eventually traces back to the android's transmitter. While physically absent from the cavern, the TARDIS's functional absence becomes crucial to understanding the temporal and spatial stakes of the threat.
