Hallie Jordan is a social worker and singer who assists Juliette Barnes in the aftermath of her plane crash.
After Juliette's plane crashed, Hallie found her as the sole survivor in a field. She phoned the paramedics and comforted her before they arrived. Juliette later overheard her singing in front of a congregation in church.
Juliette later tracked her down to her house to thank her in person for saving her life and Hallie said that she had been praying for her. When she rushes off to work, Juliette notices she's having car problems and purchases a new SUV but an embarrassed Hallie asks for her to return it to the dealership.
When Juliette regains some sensation in her legs, she tells Hallie who is delighted and they begin to form a close bond which leads to Juliette attending church. Hallie also helps children who are not so fortunate and Juliette says that she needs for her voice to be heard.
Hallie and the choir group assist Juliette with recording a gospel album but the reception from the fans and critics is not good. Juliette lies to Hallie about performing at a music festival leading to Hallie swearing at her. However, Juliette makes her peace with Hallie and the choir, who later join her onstage.
Juliette is determined to have Hallie's voice heard and gets her to perform at the Bluebird, which impresses both Avery and Deacon, who wish to produce her album and sign her respectively. Hallie is also seen having an affair with a married man, who later breaks up with her.
Following Juliette's escape from a cult, she discovers Avery has moved on with another woman but rather than being angry tells him that she just wants to see Cadence. She visits Hallie and tells her that she has lost Avery for good this time and reveals that she is pregnant.
