Bette (Invasion of the Cat-People)
From Tardis Wiki, the free Doctor Who reference
Bette was Polly Wright's cousin. Bette and Polly went to Carnaby Street together every Saturday for a time, before Polly became a companion of the Doctor. In 1994, Polly was concerned about visiting Carnaby again, in case she ran into one of her friends from the '60s, such as Bette. (PROSE: Invasion of the Cat-People)
