Plot hole: Manolito suffers a peculiar memory lapse in this episode. He's fluent in Apache, yet at first speaks to the children only in Spanish and urges Vaquero to translate. Later, though, he "recovers" well enough to speak to both Geronimo and the children in Apache.
Plot hole: When Manolito and Victoria jump from the wagon, her hat flies off and falls to the ground. The bandits ride on by, chasing the wagon, after which Mano and Victoria get up and start walking. She later laments losing her hat when they leaped, which makes no sense. Since the bandits and therefore the urgency had passed, there was no reason not to retrieve her hat before they left the area.
Apache Trust - S3-E8
Plot hole: Somewhere in old Tucson, there must have been a merchant with dozens of identical hats to sell. Here, as in other episodes, Blue's hat is lost somewhere in the desert when he's captured by the Apaches. By the next episode, though, he has it (or one just like it) back again. Lost horses, sometimes even after being killed, had a similar habit of reappearing alive and well in the following week's episode. (00:44:40)
Plot hole: Victoria asks her rescuers to take her to Rancho Velásquez. When they ask where it is, she says, "About 30 miles from here." Though she never indicates a direction, they reply, "Sorry, we're not going that way." (00:23:20)
Only the Bad Come to Sonora - S4-E3
Plot hole: Manolito trades clothes with the poor peon he meets on the road. But at the end of the episode, he has the same clothes that he gave away earlier (his usual outfit) back on again.
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.
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.
