S13E3 · Terror of the Zygons Part 3

Doctor sends Sarah to research locations

The Doctor detects escalating danger beneath the surface and devises a plan to uncover the Zygon plot before it consumes Earth. Sensing urgency, he tasks Sarah with discreet research in the castle’s vast library, directing her to study McRanald Bay and Devil’s Punchbowl—key geographic anomalies that tie the Skarasen’s path to the Zygons’ hidden agenda. The task mirrors the unfolding cyborg threat, as knowledge becomes the first line of defense against an invasion unfolding beneath the feet of the oblivious guests. By sending Sarah into the library rather than himself, the Doctor plants the seed for the next phase of their investigation, trusting her skills while positioning her to expose the truth hidden in plain sight. key_dialogue: [ DOCTOR: Task for you, Sarah. DOCTOR: Do you mind if my assistant looks through your library? DOCTOR: You might find a valuable lead. I want you to check any reference to McRanald Bay and Devil's Punchbowl. ]
