There is a continuity error that cannot be accounted for with stock footage. For his trip to Portland, Paladin is riding one of his familiar mounts--a dark horse with two rear white feet. We see him riding it as he comes up to Rook's camp, as he rides to Monk's rescue, and as they continue on away from Rook and his men. Monk rides a solid dark horse. After Monk clobbers Paladin and steals his gun, we see Paladin the next morning, riding in pursuit, still on his white-footed mount. However, when they cut to the scene where Paladin comes riding up to where Monk has tethered his horse, he is riding Monk's solid dark horse and his own white-footed horse is the one that is tethered. After Monk shoots the two men and he and Paladin leave the area, they are back on their own horses, and remain so for the remainder of the episode.
