Clara relocates the army to the theme park's castle, where they take stock of their arms: one large anti-Cyberman gun with a limited charge, five hand pulsers, and a planet-imploding bomb. Mr Clever tricks Clara and destroys the planet-imploding trigger, leaving the group defenceless as an army of Cybermen mass outside.
