Mutants reveal temporal duplication of Brigadier

The disoriented 1977-era Brigadier arrives on the mutated scientists' ship moments after the TARDIS departs, only to face Mawdryn's dire warning about temporal catastrophe. The mutants' cryptic pronouncement that their own instruments have detected a duplication of the Brigadier shocks the Brigadier into sudden realization. The revelation that the stability of both versions of himself may pose an existential threat forces him to confront the escalating chaos of the temporal paradox while the Doctor remains trapped inside the TARDIS with no clear means of escape. key_dialogue: [ MUTANT 2: There has been temporal duplication. MUTANT: He is a deviant. MAWDRYN: The Tardis will soon return. The imbalance could be cataclysmic. For your own safety you must return to the Earth at once. ]
