The Doctor, Cassie and Jimmy escape through the mine tunnels in a mine railway cart. When the cart finally exits the mine shaft, the three are greeted by Mr. Dread and the other "Alliance of Shades" android. The four androids are then destroyed Jimmy's Grandfather Night Eagle, who turns out to be familiar with aliens. The group proceed to a cave where a grey alien by the name of Rivesh Mantilax is kept. He tells the story of how his people fought the Viperox and lost years before. After his tale, Colonel Stark enters the cave and thanks the Doctor for leading the army to the alien, proclaiming the Doctor has helped him to save the world.
