Outside, Ace tells the Doctor that Morgaine bound the Destroyer with silver chains, so he loads the Brigadier's revolver with the silver bullets. Although the Doctor wants to face the Destroyer himself, the Brigadier says that he is more expendable than the Doctor, and knocks the Doctor out, retrieving his gun so that he can face the Destroyer in the Doctor's place. The Brigadier marches back into the castle, tells the Destroyer, "Get off my world!", and then empties the revolver into the monster's chest. The Destroyer explodes, and the Doctor wakes to find the castle engulfed in flames. He spots the Brigadier's prostrate form and begins to mourn his fallen friend — at which point the Brigadier opens his eyes and rises, unharmed.
