Donna 632 was grown at the partners USA factory long before the government began inplanting citizens and passing them off as partners.
Like every good idea, genetic duplication technology went astray. It became more profitable to grow whole bodies, instead of specific parts like hearts or lungs. Partner Corp began selling whole bodies with mind controls as machines. Donna 632 was grown at the Partners California factory long before a government contractor began implanting citizens and passing them off as partners. She was grown in a tank, but her father/owner eliminated the mind control all other partners had to make them follow orders.
Most would say that John was just a pawn to cover for Donna’s secrete. She wasn’t really Jack Hughes’ mechanical division director, but intelligent enough to spot his potential. He wouldn’t have thought he would even like a partner, let alone love one. His love is tested when she is horribly burned. This is further complicated when a woman leaves two little girls with them for protection from their pedophile father. Just when all seems to be coming together, they find their selves involved in helping enslaved citizens and the father kidnaps their girls.
