Cash is stunned and heartbroken by Mollie’s news, but he knows begging her to stay would be unfair. Mollie explains that her mother’s lawyers had a judge strike down the stipulation. She must return to Dallas to sign paperwork and wants to resume her life there with her mother, friends, and company. However, she admits she is torn, wanting to go but also wanting to stay, since she loves both the ranch and Cash.

Cash tells her he wants her to stay but understands why she must leave. When Mollie asks if he would move to Dallas, he refuses, explaining that his family and work are on the ranch. After speaking harshly, Cash apologizes and says they both deserve to chase their dreams. He confesses that he used to want the ranch more than anything, but now he wants her. Cash admits he fears that if she goes to Dallas, she will not come back. Mollie reassures him and invites him to come with her for a couple of days. Cash reflects on how much he has changed and agrees to go. They acknowledge the challenge of making their relationship work across two different worlds and agree to take it one step at a time.

Two days later, Cash packs Mollie’s car as the couple prepares to depart for Dallas. Wyatt arrives and reminds Cash that their mother’s engagement ring is in the safe, expressing his support for the relationship between Cash and Mollie. Wyatt acknowledges that Mollie’s mother will likely not support the relationship but suggests that where there’s a will, there’s a way. As Cash and Mollie begin their drive, he resolves to find a compromise that will allow both him and Mollie to be happy.

Mollie and Cash arrive in Dallas and immediately go to the law office so that Mollie can sign the necessary documents. She now has access to her full inheritance. Mollie and Cash have plans to meet with Aubrey the following day: Mollie has informed her mother about the romantic relationship with Cash. Aubrey was displeased and expressed distrust of cowboys, but Mollie stood up for Cash, and Aubrey reluctantly agreed to meet him.

After leaving the law office, Mollie and Cash go to her condo. Mollie’s friend and business partner, Wheeler, arrives and is visibly impressed and flustered when she meets Cash. The three of them get along well, bantering and teasing. Mollie feels a surge of happiness watching her best friend and the man she loves connect. Cash is impressed by Mollie and Wheeler’s work on their brand, but notes that they need a proper design studio with more space. His insight deeply touches Mollie, and she reaffirms her determination to make their relationship work. After Wheeler leaves, Mollie and Cash have sex.

Early the next morning, Cash calls Wyatt while Mollie is still asleep. Cash is planning on building a ranch studio for Bellamy Brooks and possibly a Hartsville storefront; he asks Wyatt for documents to help him develop the plans. Wyatt correctly guesses Cash plans to propose to Mollie. Cash admits he wants Aubrey’s approval first and reveals they had a pregnancy scare. He confesses he wants to have a family with Mollie but wishes to marry her first.

Later, as they prepare for lunch, Mollie insists Cash wear his Stetson so he can be himself with her mother. Cash is deeply moved that she is not trying to change him. At an upscale restaurant, they meet Aubrey, who is polite but tense. She pointedly asks what changed Cash’s mind about Mollie, implying he is after her inheritance. Mollie gets angry and threatens to leave, but Cash de-escalates by agreeing that Mollie belongs in Dallas.

During the meal, Mollie orders a burger and explains to a surprised Aubrey that her stomachaches have vanished since being at the ranch, concluding they were caused by unhappiness. She says she needs both Dallas and the ranch in her life. Cash steers the conversation to Garrett, noting he had many regrets. He produces a faded photograph of young Mollie on a pony with Garrett and Aubrey and explains that Garrett left him a safe-deposit box filled with hundreds of similar photos. Aubrey and Mollie are visibly moved.

Cash reveals the photo was taken at one of Garrett’s favorite spots on the ranch, then shows them sketches for a Bellamy Brooks design studio he proposes to build at that location. He presents a plan where Mollie can have a studio on the ranch to complement her Dallas work, and he could keep up with ranch work from her condo when they are in Dallas. Mollie realizes the plan could work and bursts into grateful tears. Aubrey, also moved, admits she was wrong to assume Cash would hold Mollie back. She gives Mollie her blessing to pursue the relationship.

The next morning, Cash loads Mollie’s car for their return to Hartsville. Aubrey arrives to see them off, greeting them both warmly. She tells them she wants to be part of their lives and thanks Cash for making Mollie so happy. Cash gives Aubrey a bag containing copies of all of Garrett’s family photos. Deeply moved, Aubrey hugs them both before they depart.

Two weeks later, Wheeler visits Mollie at the ranch. Mollie is planning to propose her plan of merging the two ranches (Lucky Ranch and Rivers Ranch) to Cash, and Wheeler points out this proposal is akin to marriage. When they arrive back at the New House, they find a large dinner gathering including all five Rivers brothers, John B and his daughter Sally, Goody, and Tallulah (Goody’s wife). During dinner, Mollie reflects on her love for these communal meals and her new family. Goody tells Mollie she believes Garrett’s stipulation was a deliberate, loving attempt to bring Mollie back to a place she had loved as a child.

After dinner, Mollie presents her idea, unveiling a logo for a new, combined ranch called Lucky Rivers Ranch with an upside-down horseshoe. She asks Cash to run the ranch with her as equal partners, not as foreman and owner. Cash accepts on one condition: that she marry him. Mollie joyfully accepts his proposal. Cash suggests they call the ranch Lucky River Ranch instead; he proposes removing a letter from his name since she added one to hers, symbolizing their equal partnership. Mollie agrees, and everyone celebrates their engagement.

A short time later, Cash and Mollie enjoy a day off, driving across their combined property. Cash reflects on how happy and content he is, a feeling he never thought possible. They inspect the newly repaired roads and Cash shows Mollie an old hay barn he suggests could be a storage facility for Bellamy Brooks. The brand is gaining major traction online before its launch, with notable retail interest and bright prospects ahead. Cash and Mollie have sex in the old barn.

Afterwards, they drive back toward the cabin for supper, and as they pass the horse barn, they see a group of people gathered outside. Cash sees John B aiming a rifle at Wyatt’s chest while Sally stands beside them, upset. Cash slams on the brakes and tells Mollie to stay in the truck. He gets out and approaches to ask what is happening. John B says that Wyatt did his daughter dirty. Wyatt looks desperate and says he can explain, which tells Cash his brother is in serious trouble.
