Diane Davis is the mother of Riley Davis.
When Riley was twelve, Diane began dating Jack Dalton. Both Riley and Diana believed he sold bathroom tile, although at the time he was actually working for the CIA. The two became close, with Jack saying "I love that little girl [Riley}, I always have".
One day Diana's ex-returned and began beating her up so Jack responded by severely beating the ex to scare him away. After that Jack claims he "left for (Riley's) sake" as he "didn't want to screw her up". Riley resented him from then on because she had viewed him as "basically" her father and he had left.
