The Swede stands before the elders at the Mormon fort. Aaron Hatch says, "He is not a bishop. We all heard his confession" of drowning the real Bishop Dutson. The Swede asks whether people are certain that's what he said because it was a spiritual event, "sublime to witness, yet difficult to discern." Elder Moss notes that there must be no doubt to hang a man for impersonating a bishop. Hatch says he will soon have proof: a telegraph from Bishop Finch, head of Bishop Dutson's ward.

Naomi tells Cullen about Ruth's visit, and Cullen tells her Ruth will help her make her way in town. Naomi says it's a husband's job to provide for the family as well as nurture it, "much like the life you had with your first wife." Upset, Cullen storms out, and Naomi follows him. She puts Cullen's hand on her breast, but Cullen pulls away and sends her back inside. Naomi says, "I should have known family life wasn't for you."
That night, Durant instructs Delaney to research Campbell's background. Eva enters Durant's train car and offers to accept his money "for a poke." Durant refuses, and orders Eva to take his money, eat his food, and bathe in his tub, saying, "You are one of the few people I like around here. I'll pay you for that."
Durant checks on Eva in the bath, and Eva asks if he thinks all women are whores. Durant responds that they're "God's most glorious creatures" and notes that he was fortunate enough to have loved one. Eva realizes he's speaking of Lily Bell, and asks if it gets any easier. Durant replies, "It does not."

Campbell offers Mickey, still in jail, a deal in exchange for his freedom: If Mickey signs over the title to the casino, Campbell will pay Mickey to manage it.

Durant."

Dultey arrives at the Mormon fort and hands Hatch the letter from Bishop Finch. Hatch brings it to The Swede, now imprisoned in a cage. The letter says Bishop Dutson is 5'6" tall with brown hair and "portly girth," but The Swede insists he's Bishop Dutson and that he's never met Bishop Finch. The Swede suggests the telegraph author "has lied to support your delusions," and Hatch responds that the elders will sentence The Swede to hang. The Swede questions their authority to execute a bishop, and proposes a solution: Bring Brigham Young to the fort, "and I will abide by his judgment."
Naomi arrives at church, but Cullen is still out working on the mountain. Ruth preaches about loving "God, as well as our neighbor" and confesses to passing judgment on another. "I do not deserve salvation," Ruth declares, "None of us does." Naomi abruptly walks out. Ruth continues, "Only the blessed mercy of Jesus Christ can save us."
