Brigadier learns Doctor is in TARDIS ruins

The 1977-era Brigadier enters the mutated scientists' vessel to find the TARDIS vanishing, confronting Mawdryn about the Doctor's unexplained absence. Mawdryn reveals the Doctor is trapped inside the ship amid temporal distortions, while mutant voices confirm two versions of the Brigadier exist—a paradox he must not witness. The urgency escalates as Mawdryn warns that the Doctor's return could destabilize time itself, forcing the Brigadier to abandon his mission and flee Earth before catastrophe strikes. The exchange exposes the severity of the Doctor's plight and the fractured reality now threatening to collapse around them. key_dialogue: [ MAWDRYN: The Doctor is in the Tardis.

"Mawdryn's attempts to reassure and urge the Brig '77 into the transmat (Act 2) parallel his earlier appeals to the Doctor to save the mutants through shared suffering (Act 1). Both scenes show Mawdryn manipulating others to avoid his own fate—ultimately failing."
