Joan Harris is the older sister of Pat Evans, Jimmy and Geoffrey Harris.
Backstory[]
Joan was sent to a nursing home when her sister, Pat Harris, was four years old as she had Down’s syndrome. She later married Michael, who also had Down's syndrome. Her mother Lydia Harris disowned Joan, claiming that she had died at the age of twenty-two. On 20 August 2007, Len Harker helps Pat to break in to a hospital, where they discover that Joan hadn't died aged 22 as Pat had been told, but had been sent to a different hospital in 1989. However, while running from the police, Len drops the paper which reveals which hospital she had been sent to, but he searches the internet and finds the location. He takes Pat there, where they discover that Joan had only died a few years ago, and that she had gotten married in 1963.
