Quinn's Research Notes, Globe, and Device

The Doctor brings Quinn's handwritten notes, a prehistoric globe mapping Earth 200 million years ago, and associated devices (including climbing pitons) from Quinn's office into the UNIT conference room after discovering Quinn's death. These items—notes detailing Silurian collaboration, the globe illustrating ancient cave systems, and the pitons used for exploration—draw attention from the Brigadier, Liz, Hart, and Baker during heated debates about the cave invasion. The Doctor uses them to expose Quinn's unauthorized Silurian contacts and potholing ventures, prompting Liz to scrutinize details (e.g., the globe's markings) while the Brigadier pushes for military action.

S7E7 · Doctor Who and The Silurians Part 3

Doctor discovers Quinn’s Silurian research

The globe, depicting Earth 200 million years ago, is the centerpiece of the Doctor’s discovery. Its markings confirm the Silurian era and provide visual proof of Quinn’s collaboration with the ancient reptilian species. The Doctor and Liz examine it closely, tracing the continents with their fingers as they piece together the implications of Quinn’s research. The globe’s presence in the cabinet, alongside the notes, solidifies the Doctor’s suspicions and elevates the stakes, as it becomes clear that Quinn is exploiting the Silurians for scientific knowledge, risking interspecies war.

Before: Locked inside Quinn’s cabinet, hidden from view and untouched until the Doctor pries it open.

After: In the Doctor’s hands or on the desk, examined and discussed as evidence of Quinn’s dangerous ambitions. Its discovery is a turning point, as it forces the Doctor to act swiftly to prevent catastrophe.

S7E7 · Doctor Who and The Silurians Part 3

Doctor confronts Dawson over Quinn’s secrets

The Silurian globe is the pivotal clue that confirms Quinn’s dangerous research. Pulled from the cabinet by the Doctor, its ancient geography (Earth 200 million years ago) and markings immediately reveal its purpose: a tool for studying the Silurian era and their cave systems. Liz’s identification of the landmasses (‘all bunched together’) and the Doctor’s rapid interpretation of the notes create a moment of eureka, but the discovery is bittersweet—it proves Quinn’s alliance with the Silurians, yet the Doctor is unable to fully exploit this lead before the Brigadier interrupts. The globe becomes a ticking clock: the more the Doctor learns, the more urgent the threat feels.

Before: Locked inside Quinn’s cabinet, hidden among other research materials.

After: Left exposed on Quinn’s desk or in the Doctor’s hands, now a piece of evidence that UNIT (and potentially the Silurians) will seek to control or destroy.
