Children (The Eleventh Hour)
From Tardis Wiki, the free Doctor Who reference
These two children, were the daughters of a mother who was in a coma, in the Royal Leadworth Hospital in 2008. They appeared when Prisoner Zero used their mother's body to trick Amy Pond and Rory Williams into thinking they were hospital patients. They disguise soon failed, when Amy noticed that one of the children started to speak using their mother's voice. (DW: The Eleventh Hour)
