H-Two

H-Two was a clone of River Song.

She was part of a second batch of clones created by Madame Kovarian after River failed to kill the Eleventh Doctor at Lake Silencio. Her twin clone was H-One. Like River and her fellow clones, H-Two was raised on bedtime stories about the Furies and trained to be an assassin. She grew up considering Kovarian to be her mother and believed Kovarian's promise to give her a proper name after her first mission. She repeatedly tried to attack River after H-One's death because she believed River had killed H-One. (AUDIO: The Furies)
