The love triangle, especially between brothers, was done a few times on Gunsmoke. It is a pretty trashy story, and it never gets better. In this case, one brother always looked out for the other. When the younger brother commits a crime, the older brother takes the blame. That did not make much sense. Especially when the younger whelp brother confesses to Matt Dillon, the U.S. Marshal. The crime took place three years earlier. Dillon should have arrested whelp, but he just totally lets it slide.
The older brother, Stedman, is also upset that his whelp brother married his girlfriend. Right there, I am thinking this is a Jerry Springer episode. Who leaves a girlfriend behind for three years and expects her to be virgin pure when he comes back? As Dillon says, Stedman is still a kid.
So while Stedman is making threats of killing his brother, and Dillon is violating his oath by not arresting the whelp after he confessed, nothing much is happening. The highlight of this episode is Doc Adams talking about poker philosophy, and Chester reading a book about poker and discussing it with Dillon.
Eventually the big confrontation does not happen, thanks to Dillon pulling out his ace, which changed Stedman's whole attitude. Stedman eventually moves on to become Oprah's boyfriend.
These characters, like most of the neighbors on Gunsmoke, are never on the show again. It would have been nice to see how baby Stedman turned out. It would have been nice if some of the guest characters from previous seasons had been brought back now and then.
