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)
