In 2010, Oprah discovered a bombshell family secret: She had a half-sister who had been put up for adoption at birth. Oprah and her family chose to reveal the news on their terms, and Oprah introduced the world to her half-sister, Patricia Lee, on an episode of 'The Oprah Show.' But there's something even more remarkable about this story. As she fights back tears, Oprah shares something extraordinary about Patricia.
'Oprah: Where Are They Now?' airs Sundays at 10 p.m. ET on OWN.
