Lamorne Morris is opening up about the final episode of Fargo season 5. While inspired by the 1996 movie, the show trades settings every season, jumping to different locations and time periods within the Midwest. Every season focuses on a different mystery, which left season 5 to focus on Sheriff Roy Tillman's cruel treatment of his estranged wife, Dot Lyon. Throughout the season, Morris' Deputy Witt Farr often tries his best to protect her.
