The April 12 episode of Marshals focused on Kayce confronting his anger toward his late father John Dutton and guilt about pursuing a new relationship after Monica's death. The team hunted an ex-con targeting a federal judge's family, revealing the husband's secret as an arms dealer. Subplots involved romantic tensions among the marshals.
In Marshals season 1 episode 7, aired April 12, Kayce shared wisdom with Fallon, daughter of federal judge's husband Blake, who was secretly an international arms dealer via his non-profit. Kayce told her, 'No father is perfect. Once you realize he was just trying to protect you in his own messed up way, your anger will fade. I just hope that if you ever do forgive him, he's still around to hear it.' Fallon also asked Kayce about his father John's killer, but he said he does not dwell on it, despite knowing Sarah Atwood orchestrated the death, as referenced from Yellowstone connections. Kayce spent time with Dolly Weaver, riding horses and sharing backstories, marking one year since Monica's passing. Her father proposed buying Kayce's ranch for his cattle operation at dinner, prompting Kayce to end the meal early. Weaver said, 'We can both come out winners. Think it over.' Dolly apologized, but Kayce rejected her goodnight kiss, later telling Andrea he felt like cheating on Monica. Andrea encouraged him, contrasting John's all-consuming grief after his wife's death, and asked if Monica would want him isolated. The episode closed with Kayce riding off with Dolly at sunrise. Other marshals faced relationship challenges. Cal saw Belle's husband Jared with another woman but stayed silent until after drinks at HQ, learning of their open marriage for their son's stability.

Miles asked Maddie out at the Bullet 'n Barrel, unaware she is Cal's daughter.
