Brigadier demands the Doctor urgently

The Brigadier’s violent summons fractures time itself, forcing the Doctor to materialize in the TARDIS. The mutated scientists’ agony twists reality, their suffering bleeding into the corridors of the ship. The Doctor faces an impossible choice—his regenerative energy as the only cure for souls trapped in endless decay—and the Brigadier’s frantic state masks deeper terror about the collapsing timeline. Tegan and Nyssa soon share the same wretched fate, accelerating the Doctor’s dread that time may not heal these wounds. The event tests his limits, trading mortality for mercy while protecting those he holds dear. key_dialogue: [ BRIG '77: Doctor! Where is he? ]
