Continuity mistake: At the end, despite an earlier emphasis on the necessity of wearing one's hat in the desert, John rides out of town without his. Victoria, who wore John's hat when they crossed the desert, isn't wearing it either. And of course, the "lost" hat reappears on John's head in the next episode. (00:39:20)
Continuity mistake: Victoria starts the ill-fated journey wearing culotte-style pants. When they get stranded without food, clothes or other provisions, the pants somehow turn into a skirt.
