Kelly was the wife of a man killed in an car accident. She donated some of his organs to Jackson Prescott.
Kelly was brought into Seattle Grace Hospital where her husband was declared brain dead. She had to unplug him but at the same time, Jackson Prescott was dying. George discovered the patient and Richard spoke with her and even though the man wasn't a donor, he pleaded with her to donate his organs.
At first, she refused, but after he spoke with her again, telling her that he couldn't take his organs to heaven and that they would be uselesss, she complied.
Kelly was married, but her husband was declared brain dead after a car accident. He would hold Kelly's hands when she got scared.
