Doctor reveals engineered Cybermen plague

The Doctor transmits his findings to Commander Stevenson via video link, exposing that the crew’s annihilation stems from an engineered pathogen rather than organic infection. By detailing the virus’s unnatural behavior—scratching metal, inducing instant unconsciousness, and tampering with radio logs—he dismantles the plague narrative, revealing Kellman’s complicity in the conspiracy. This moment forces the allies to confront the true scale of sabotage aboard the dying Ark and the presence of long-lost Cybermen machinations. key_dialogue: [ DOCTOR: Have you noticed these rather strange scratches, Commander? DOCTOR: Everything's important. Well, well, well. DOCTOR: Whatever it is that's attacking your crew, Commander, it's certainly not a plague. ]
