Doctor Reveals Toymaker’s Enduring Threat

The TARDIS’s master switch is referenced indirectly as part of the Doctor’s earlier actions to escape the Toymaker’s planet. While not physically interacted with in this specific event, its presence looms as the mechanism that enabled their dematerialization and temporary safety.

After: Deactivated but ready for future use; its role in this event is more symbolic than functional.
