Jackie Fitzgerald is an unseen character in The Lost and Damned.
She is the wife of Jim Fitzgerald and the mother of their child. She is mentioned a few times during the story of The Lost and Damned, and it is shown that Jim really cares about her. Jim claims she's a "really good woman" and that she's "normally nice" to him but that she often "drives him batshit crazy" by nagging him because of his antics with The Lost. Following Jim's death, Johnny Klebitz tells fellow Lost member Angus Martin that he will continue to financially support Jackie and her child as he "owes [Jim] that".
