Five Sundowns to Sunup - S7-E12
Other mistake: The Lassiter brothers have kidnapped a judge and a posse is searching for them. One of the men says they should quit for the day because "it's almost sundown." Judging by the shadows of the men, their horses and nearby trees, the time appears to be around 1 PM.
Character mistake: When Hoss takes Timmy for a horseback ride, after they both dismount by the lake, Hoss calls Timmy by his real name Johnny (Whitaker) and not Timmy.
Adam Cartwright: Let's go back to the Ponderosa, Pa. This isn't any of our affair.
Ben Cartwright: We can't ignore the rest of the world. We're the only stabilizing influence in the country.
