S11E6 · Invasion of the Dinosaurs Part 2 graph

Brigadier reveals dinosaur invasion crisis

Under pressure from the Brigadier, the Doctor and Sarah enter a UNIT command center mapping an unprecedented threat—prehistoric creatures materializing across central London. The Brigadier reports eight million evacuations, unexplained disappearances of the monsters, and a military response paralyzed by the phenomenon’s impossibility. The Doctor’s temporal displacement theory offers the first coherent explanation. Tensions flare when General Finch arrives, dismissing science outright, dismissing Sarah’s eyewitness account from medieval England, and authorizing deadly force. The confrontation crystallizes the clash between disciplined bureaucracy and imaginative inquiry as trust erodes and the true nature of the threat remains beyond conventional understanding.
