Sandra (The Christmas Invasion)

Sandra was a female human who lived in the Powell Estate in the 21st century with her partner, Jason Overton. On Christmas 2006, when Jason was possessed by Sycorax blood control, he walked to the roof and threatened to jump off. Sandra was scared, but relieved when the Tenth Doctor turned the control off. She and Jason later frolicked in the Christmas snow. (TV: The Christmas Invasion)
