Having just completed her album, Juliette pushes full steam ahead to set a release date and get out on tour. But a confrontation with Rayna leads her to grab her album and leave Highway 65.

Later he finds out she's fired Glenn, and done the unthinkable by hiring Jeff Fordham as her new manager.
Layla finally gets clued into Jeff's manipulative and controlling ways, and discovers he intentionally sabotaged her job and relationship with pop diva Jade St. John. She confronts him, after violently attacking his car with a golf club. But his explanation that he did it all because he was afraid of losing her seems to work, because she forgives him.
