Diane Thomas, born Diane Matthews, learned early on to make her own way. Changing her name at 21 so her law career wouldn't be influenced by her Father's reputation as a Judge, she soon found her career as a Lawyer to not be as satisfying as she had believed. She eventually settled on the U.S. Marshal's service and soon found herself partnered with John Waters.
The pair worked mainly in Fugitive recovery, proving to be successful in many of their cases and growing to be close friends. Their entire status as friends changed with a kiss, and Diane did the only thing she felt was right at the time and pushed him away, she cared to much for him to let him sacrifice all he knew for something that may, in the end, turn into nothing as she had a history of quickly growing dissatisfied with her romantic partners. It took her time to realise that dissatisfaction came from her growing intimacy with John and found herself comparing every man to him unconsciously.
Trying to drive him from her mind and forget the mistake she made in pushing him away, she almost married a high school sweetheart more interested in her families wealth then in her, it was through an anonymous 'friend' she discovered the duplicity.
Eventually she ended up with John in Athens at an international conference for those in their field. During that time the pair admitted to their feelings for each other, and Diane, already planning on resigning, put the motion in action as they finally come together. It was during that time that then infection hit, the city growing increasingly frantic as the infection spread. John and Diane escaped the city by joining a family on their boat and heading inland to try to get behind the worst of things......
