Continuity mistake: The number of outlaws in the gang mysteriously increases during one chase scene. For most of the episode, there are only three of them. When they gallop off after Manolito, there are suddenly five. Next scene, there are three again. (00:20:35)
Plot hole: The scriptwriter here apparently never saw earlier episodes in which it was well-established that Manolito spoke fluent Apache. In a scene where he attempts to sneak past two braves while disguised as an Apache, he suddenly can't speak the language when they challenge him.
Plot hole: This episode comprises a flashback to the year 1866, but it sets up a chronology that completely contradicts the rest or the series. It contends that the Cannons moved west to Arizona in 1867. In the pilot and throughout the series, it was stated that they arrived in Arizona in the 1870s, at least ten years after the U.S. Civil War.
