If the previous episode of Under the Banner of Heaven was devoted to Dan (Wyatt Russell), then the latest episode, "One Mighty And Strong," explores Ron (Sam Worthington). In fact, the episode is named for him. Much of the episode is dedicated to Ron's evolution throughout the series thus far. Once considered the Lafferty family's black sheep for his construction business, Ron was goaded back into the family's fold by Dan previously. "One Mighty And Strong" is an examination of how much Ron has changed, setting the series’ final episodes into motion.
