Abby McSweeney is Jay Halstead's wife who he thought he was divorced from. They met each other in the Rangers. They got married on night whilst they were very drunk in Vegas, after a fellow rangers funeral.

In Remember the Devil, Abby returned and revealed she hadn't filed their divorce papers that Jay had signed all those years ago. She says she needs to because she's getting married. However, she tells him later on that she's not getting married, but she's back because she still loves him. Jay tells her they can't be together and that she deserves someone who'll love her back.
