Astrid is an intergalactic waitress. She meets the Doctor on the spaceship Titanic and helps him thwart a devious plan to destroy the ship as well as the people of Earth. Aside from being caring and loyal, she's also quite hot. And being played by THE Kylie Minogue certainly helps that quite a bit. Initially, Astrid was devised as a long-time companion, but by the time the episode was ready to film, she was reduced to a one-time appearance. Pity, having Kylie Minogue in more episodes would be quite a treat.
