When Teddy and Rayna announce their plans to divorce, Maddie takes it hard and begins to rebel against her mother. She ditches school to attend a free concert thrown by Juliette, but ends up being injured in a stampede.
Towards the end of the season, she discovers that Teddy is not her biological father. Distraught, she confronts Deacon with this information, which leads to him returning to his drinking ways, because he hadn't known either. When Rayna and Deacon are involved in a car crash, Maddie starts to feel guilty, but Juliette tells her not to, and gives Maddie her number so that she can contact her at any time. She reveals to Juliette that Deacon is her biological father.
Rayna is soon released from hospital, but her relationship with her elder daughter continues to be tested. When she and her daughters attend a charity benefit gala thrown by Lamar, Maddie sees her grandmother's engagement ring around Peggy's neck, and runs away. Juliette comes to her aid, and later calls Rayna to reassure her Maddie's safe. She also promises to keep the news of Maddie's true paternity a secret.

They start to meet up for guitar lessons and she performs a duet with him at her open mic performance, which angers Teddy, leading to a confrontation between the two men. When Deacon experiences writer's block he turns to Maddie for help and they write a song together. At Juliette's induction ceremony at the Grand Ole Opry Maddie goes to see Juliette in her dressing room and greets Deacon with a hug, but Maddie tells him Juliette already knows they're father and daughter.
When Maddie is playing guitar Teddy walks in to talk to her about her feelings towards Luke and Rayna's engagement. She tells him that she can't talk to him about it because she wanted Deacon and Rayna to get married and she knows that he hates Deacon.
