Jill Sandbrook
From Tardis Wiki, the free Doctor Who reference
Jill Sandbrook was part of the Master's experiments to model a war. She was very officious on her duties and chastised Jamie McCrimmon and Polly Wright for being late. She obsessed over rotas and demarcation. She then helped when the aliens invaded earlier than planned. Eventually the condition fell from her and she helped Jamie, Ben, the Second Doctor, and Polly to defeat the Master. (AUDIO: The Home Guard)
