Hitler was punched by Rory Williams and forced into a closet. In the confusion, Hitler shot Mels, causing her to regenerate, revealing herself as Melody Pond. Melody poisoned the Eleventh Doctor, shutting down his regenerative abilities. Having later captured Melody, one of the biggest war criminals in history, the Tesselecta computer told the Doctor that a religious order called the Silence wanted him dead. Amy Pond caused the crew to evacuate from the ship to escape from the antibodies, releasing her daughter. After the Doctor succumbed to the poison, Melody used up her remaining regeneration energy to revive him, once she learnt that she would become his closest friend River Song one day. The Doctor then took River away to the Sisters of the Infinite Schism to recover. (DW: Let's Kill Hitler)
