Secretaries, librarians... who else, who else... ah yes, scientists! Scientists are hot! And that's just who Liz Shaw happens to be. She is an Oxford-trained scientist, hired by the Brigadier to be UNIT's scientific advisor. To add to her hotness, she holds degrees in several fields, including physics, astronomy and medicine... so I guess that also makes her a doctor -- and doctors are also hot. Her first encounter with our Doctor came in the form of helping him defeat the Autons and the force that controlled them.
