Jessica Fitzgerald was a waitress working at the wedding of Laurie Shelby and Sinead Shelby.
In June 2019, after Liberty Savage tells Brody Hudson about Georgia, a woman who Laurie had sexually assaulted and refused to report it to the police, Brody realises that Laurie must have done the same thing to other women. Brody asks Sinead if she can remember anyone that Laurie had attacked (so Sinead can get justice after Laurie raped her). Sinead tells Brody about a waitress, Jessica, from her wedding night, as well as Rhonda, a shop assistant who hit Laurie with a shoe. Sinead says that she always thought something went on between Jessica and Laurie. Brody and his girlfriend Sienna Blake (who Laurie had sexually harassed for months) managed to track Jessica down and went to talk to her.
Jessica tells Brody and Sienna that she was working as a waitress for Laurie and Sinead's wedding. She says that she and Laurie were flirting that night, and that he followed her when she was going to get more wine. Brody and Sienna assume that Laurie attacked Jessica after he followed her. However, Jessica tells them that she had consensual sex with Laurie that night, which makes Sienna furious. She tells Brody and Sienna that she's sorry about Sinead, but won't lie for her in court and that she's on her own before leaving.
