Turlough and Norna encounter the Tractators

Turlough and Norna push deeper into the alien cavern despite his unease, the glittering walls masking the true horror ahead. Turlough’s casual bravado crumbles when the cavern’s hidden mechanisms reveal the looming forms of the Tractators. Their rhythmic advance toward the intruders delivers the first unmistakable confirmation that the colonists’ suffering is not random chance but the work of an intelligent, predatory force. The moment strips away the Doctor’s deductions and forces Turlough into direct confrontation with the entities whose existence his premonitions had only hinted at. key_dialogue: [ TURLOUGH: Can we go back now? Please? NORNA: Oh, come on, chicken. TURLOUGH: I'm not frightened! I'm just thinking. TURLOUGH: No, wait, I'm coming. ]
