Sally Cheapside was the daughter of the Duke of Cheapside. She claims to have killed her mother, which her father lived in denial about (despite Sally telling it to him directly). Her father kept trying to keep her from growing up. However, Sally ended up pregnant, addicted to opium and in love with poet Percy Shelley.
After they had been mugged by Mr. Blackadder, she insisted that her father did nothing to defend her honour. Her father responded by yelling "Oh shut your face, you pregnant junky fag-hag!"
