This revelation shocks both the Brigadier and the Doctor, exposing an unseen psychic link and supernatural interference in the Brigadier’s fractured memories.

Mobile Transmat Capsule (Turlough's Device)

The transmat capsule is already activated and entered by Turlough prior to this event, positioning him inside the device as the Doctor and Brigadier converse nearby. Its smooth, dark surface hides its advanced functions behind a façade of simplicity, leaving Turlough grasping at its mechanisms in ignorance. The capsule's presence is the catalyst for the Doctor’s urgent pivot from interrogation to action.

TARDIS Emergency Coarse Utility Blankets

The coarse utility blanket from TARDIS storage is draped over the Brigadier in sickbay, its folds creating the concealment where the Black Guardian’s crystal is hidden. The blanket’s scorched edges reflect past medical emergencies in this space, providing both camouflage and a physical trace of time’s passage since the 1977 incident.
