Some will get jealous and someone will run away from home in the next episode of "Nashville" season 4.

Based on the synopsis for the episode titled "Didn't Expect It To Go Down That Way," Juliette will get jealous over Avery's closeness with Layla, who have been getting really close since they started working together. While it is obvious that Layla likes Avery, Avery is unsure about his feelings for Layla because of his ex-wife Juliette, who just recovered from postpartum depression and wants to patch things up with him.

The promo video for the episode shows Avery and Layla getting too close as they sing together on stage. While they perform, Layla throws Avery seductive looks, getting into Juliette's nerves.

The episode will also follow Juliette as she becomes the best tour companion for Luke, who will have to look for a new artist for Highway 65 after the sudden disappearance of Riff.

Meanwhile, Maddie gets mad at Deacon for stopping her from playing in a bar she's singing in. Deacon dragged her out of the bar after seeing a male patron touching her inappropriately. Furious, Maddie runs away from home, causing another letdown for Rayna since she has to find her missing daughter before she could go on with her tour. The promo trailer shows Rayna crying in front of Juliette.

Episode 16 will also see Autumn trying to cause a strain in the relationship of Scarlett and Gunnar.
