The Eleventh Doctor's TARDIS, damaged by Mels' gun, crash-landed in Hitler's study in Berlin, inadvertently stopping the torture of Hitler by the Teselecta. In the confusion, Hitler shot Mels, causing her to regenerate, revealing herself as Melody Pond. Hitler was punched by Rory Williams and forced into a closet. Melody poisoned the Eleventh Doctor, shutting down his regenerative abilities. Having later captured Melody, one of the biggest war criminals in history, the Teselecta computer told the Doctor that a religious order called the Silence wanted him dead.
