Juliette Barnes is learning how to apologize. In “Nashville” Season 4, episode 15, the country star needed to get her manager Glenn back. She fired him last year on the ABC drama during her breakdown, but getting back in his good graces isn’t so easy. Juliette realized that even if he doesn’t have room to manage her, she still needs her father figure in her life.

When episode 15 kicks off, Juliette (Hayden Panettiere) decides that even though she recently turned down a big movie role, she still wants to get back to work. She doesn’t know where to get started, so she needs her old manager, Glenn (Ed Amatrudo). But like Avery (Jonathan Jackson), he isn’t ready to forgive and forget just yet. He kicks her out of his office when she tries to make amends.

Juliette goes to Avery to ask if Glenn hates her. Avery tells her to be honest with him. She needs to admit that she needs him, but Juliette thinks she should just back off. Avery is surprised. Juliette never backed from a challenge down before, but the starlet claims that’s the pre-rehab version of herself. “There was a lot to love about her,” Avery says of the old Juliette.

Avery brings Glenn to the Grand Ole Opry, and Juliette shows up for a surprise performance. Glenn turns to walk away after he sees Juliette. “I want to dedicate this song to the man that I’ve always thought of as my father, and every word of it is the truth,” she says. It brings tears to Glenn’s eyes and he can’t leave.

Backstage, Juliette promises Glenn it wasn’t an act. She starts crying as she tells him that she needs him and misses him. Juliette says that even if he can’t be her manager, she at least needs him in her life. Glenn says that he might be able to swing being a father figure and her manager again.

Juliette brings Avery a six-pack of beer and thanks him for helping her. She wants to make sure he knows that he is appreciated.

Layla (Aubrey Peeples) sees Avery with his ex, and it makes her week even worse. The struggling artist is still hurt that Autumn Chase (Alicia Witt) dropped her as an opening act, and there are no other spots available.

Rayna, however, was doing her best to help Layla. When the artist can’t get on a tour, Rayna considers going out herself. She thinks just 10 dates could help launch Layla’s album.

She tells Deacon (Charles Esten) about her plan, and her husband is shocked. Rayna wants to jump out on the road with Deacon in her band, but he isn’t so sure about leaving Nashville. He’s happy running the Beverly and parenting Maddie (Lennon Stella) and Daphne (Maisy Stella). His tour days might be over.

Layla doesn’t realize that Rayna is planning a tour. She just knows that there aren’t any artists who want to tour with her, so she goes to Luke (Will Chase) behind Rayna’s back. Luke is supposed to bring on a new artist from his own label, but Layla asks him to put business aside and plays the dead boyfriend car. She brings up Jeff (Oliver Hudson) and reminds Will that he “knows what happened in a way nobody else does.” It’s enough of a guilt trip to get her a spot on Luke’s tour.

Bucky (David Alford) is thrilled, but Rayna isn’t happy. She feels like her artists keep abandoning her. Bucky reminds her that she has a successful label. After Rayna sings with Autumn on stage, she admits that she doesn’t want to tour just for Layla. As an artist, she needs to get back out on the road.

She might have some second thoughts after she finds out what trouble Maddie has gotten into now. Cash (Jessy Schram) says that she used to sneak out of the house to play cafes, and Maddie decides that’s what she should do. That wasn’t what Cash intended, but she still books a gig for the teenager.

Daphne overhears their plans and reveals to Deacon that Maddie isn’t at a coffeehouse, as she told her father. She’s playing at a bar. He goes down to the venue and arrives in the middle of Maddie’s set. Deacon sees a man touch Maddie’s legs and he runs up to the stage to drag his daughter home.

Cash stops them on the way out and gets into a fight with Deacon. She yells at him for standing in Maddie’s way, and Deacon openly admits that his daughter is more talented than he’ll ever be. But Deacon is her parent, not her agent. He tells Cash that she needs to stay away from Maddie.

Elsewhere, Scarlett (Clare Bowen) is a little starstruck by Autumn, but she quickly realizes that her idol might not be the nicest star. She fires a new guitarist in their first tour meeting. Scarlett thinks it was demeaning, and their manager says Autumn has a habit of firing people. They need to avoid irritating her.

Things get awkward for Scarlett and Gunnar (Sam Palladio) when Autumn digs into their history. They try to avoid going into details, but they eventually have to explain that they broke up after Gunnar proposed. Gunnar tries to brush off the incident, but once Autumn brings up the proposal again, Scarlett has to confront her about it. Autumn promises to drop the topic after Scarlett says it makes her uncomfortable. She says that she respects Scarlett for sticking up for herself.

If the Exes do have to leave Autumn’s tour at some point, they might be able to join Layla during Luke’s shows. It looks like the headliner could be down another opening act. Riff (Steve Kazee) is supposed to be on tour with him, but just a couple days before leaving, Riff’s wife Heidi (Julia Barnett Tracy) comes to Luke in tears. “Two days ago, he packed a bag and left,” she reveals. Did the country veteran get cold feet before his comeback? Viewers will have to tune in next week to find out.

Elsewhere in “Nashville” Season 4, episode 15:
