Times Are Changing (1) - S9-E1
Character mistake: Almanzo says he hasn't seen his brother Royal in 10 years, but in fact he saw him not long ago as he looked after his 2 sons who were terrors, and at that time Royal didn't even have a daughter.
Suggested correction: Royal's wife was pregnant when he visited years before Laura had the baby.
What happened to Pearly Day? Almonzo's younger brother?
Not sure if this varied in the show, but in real life Pearly Day had six children and died in 1934 just a month prior to his 65th birthday.
Almanzo had 2 brothers. Royal and Jenny's dad, the one that was dying.
That may not work, unless Laura and Almonzo were not married yet at the time of Royal's first visit, but it is a good suggestion.
In the TV series, the episode that they were taking care of the boys was only six episodes before Laura found out she was pregnant, and Nellie's babies were still babies throughout that time so it wasn't that long. And Rose wasn't that big When they came to visit, so it was probably only 1 1/2-2 years of a time gap. Also, when Royal and Jenny came to visit, Almanzo introduced Royal to Laura as if they had never met before.
It was NOT years! Royal, his wife and 2 sons visited Almanzo in Season 7. His wife did announce she was pregnant in the end. However, when Royal comes back to visit with Jenny, at the beginning of Season 9. If Jenny is supposed to be the baby Royal's wife was pregnant with then she would have still been a year old or 2 at most. They do explain that his wife died, but what about those boys? They would have been early teens by then. Nothing is ever said about them or why they aren't with Royal.
But Laura says "glad to finally meet you Royal", when he came with Jenny. But she met him when he came with the boys.
Continuity mistake: A criminal steals Fish's gun and holds the squad hostage. He has a handcuff on one wrist with the other one hanging. The hanging cuff goes back and forth between being open and being closed throughout the scene.
Factual error: There is no physical way that Steve Austin could perform most of his superhuman feats of strength in the ABC television series, due to the fact that they simply replaced his arm and legs, but didn't rebuild or reinforce the rest of his skeleton and muscles to handle the physical loads. Interestingly, author Martin Caidin (creator of Steve Austin in his novel, "Cyborg") actually did describe an incredibly complex whole-body rebuild that included vertebral reinforcement and ribcage and pelvis replacement, which was far more scientifically-accurate than the subsequent ABC television interpretation. ABC only accepted the series on the condition that it was less technical for their audience.
Backlash of the Hunter - S1-E1
Continuity mistake: Rockford's car has license plate number "835-OKG" at the front of his car, but license plate number "853-OKG" at the back of his car, a few times during the episode. (00:35:40 - 00:37:50)
