'Hell on Wheels' sneak peek: Will Cullen let Ruth go?

The death of Sean (Ben Esler) reverberates in this week’s episode of Hell on Wheels as Ruth (Kasha Kropinski), feeling as though she failed him, decides she wants to leave town. Cullen (Anson Mount), however, doesn’t want her to go. Watch our sneak peek below and try not to ship them. Then, watch another clip teasing the return of the Mormon father whose son Cullen hanged in the season premiere. Bohannon has bigger problems than whether Ruth gets on that train: “All the guns in the world will not protect Cullen Bohannon.”

Hell on Wheels airs Saturday at 9 p.m. ET on AMC.
