Continuity mistake: Marshall Dillon buries an outlaw at Sarah's place. He installs a wood cross at the grave. Sarah comes out and they talk. When she leaves, the scene cuts back to Dillon and the cross is missing.
Kitty Russell: Matt, you can't account for everything that happens to people who touch you. You know, I learned a long time ago, there are some things in this life that you just accept the way they are.
U.S. Marshal Matt Dillon: That's pretty deep for a redhead.
Kitty Russell: I'm a pretty deep redhead.
Trivia: Although they played father and son in this episode, Jack Elam was only six years older than Harry Dean Stanton.
