Turlough reveals Tractator infection memories

Range recognizes the urgency to act while the terrain above worsens, underscoring how personal trauma now intersects with existential threat. key_dialogue: [ TURLOUGH: Growing. Breeding. Spreading the infection. TURLOUGH: No! It's evil! I can't look! RANGE: Right, that's enough. We must get him out of here. ]
