Sierra is a fictional character portrayed by Dichen Lachman in the Fox science fiction series Dollhouse, created by Joss Whedon. Within the series' narrative, Sierra is an "Active" or a "doll", one of a group of men and women who can be programmed with memories and skills to engage in particular assignments; in their default state, Actives are innocent, childlike and suggestible. Before having her memories wiped, Sierra's name was Priya Tsetsang. Although Sierra does not exhibit the same self-awareness that Echo has, she develops feelings such as love in her doll state.
