Party guest (The Lazarus Experiment)

This Party Guest was a female human who lived in London in the 21st century. She attended Richard Lazarus's party. When the Tenth Doctor warned everyone to leave, she joked the most dangerous thing there was choking on an olive. Ironically, she was subsequently attacked and drained by the mutated Lazarus, leaving nothing but her withered husk behind.. (TV: The Lazarus Experiment)
