Wadi

Wadi was a clone of River Song.

Wadi was created on Demons Run by Madame Kovarian, along with six other clones. Sometime after escaping Demons Run, she was tending to fuel cells with Lake and when one of the cells blew up in Lake's face and the explosion caused him to regenerate. Amazed, she told her fellow clones about what happened and looked to Lake as their spiritual leader. Wadi was later murdered by Lake in his quest to discover how many times he could cheat death.
