Turlough intercepts Brigadier from lab entry

Turlough urgently races through the spaceship corridors and intercepts the Brigadier just as he prepares to enter the dangerous laboratory. He pleads with sheer desperation for the officer to halt his advance into a situation far more hazardous than he understands. The interruption forces a tense confrontation between them, deepening the rift in their already strained alliance and raising the immediate stakes of the mission while prodding closer to the crisis at the heart of the Doctor’s impossible choice over regenerative energy.
