Jean Rock
From Tardis Wiki, the free Doctor Who reference
Jean Rock was the Commandant's secretary at Gatwick Airport. She assisted the Second Doctor in defeating the Chameleons. She made calls to the various airports to which the Chameleon planes flew. She feigned illness, causing the Chameleon Nurse Pinto to leave the medical centre so the Doctor could search it. When the Chameleon Meadows was cornered, she stopped his escape by rolling a chair at him. She and Samantha Briggs searched for the originals of the bodies taken over by the Chameleons, finding them in the car park. (TV: The Faceless Ones)
