While on the turkey shoot, Hawthorne reminds John-boy that his great, great grandfather was the first Walton to settle on the mountain. This will be contradicted twice in later seasons. In The Pony Cart, we are told it was John-boy's great grandfather, while in Founders' Day, we are told it was his great, great, great grandfather.
Although broadcast as the fourth episode, this was actually the first episode of the show to be filmed.
At least part of this episode takes place on 10th March 1933, as witnessed by the report of the Long Beach earthquake on the radio. This is the first episode to which a specific date can be ascribed.
In the closing narration, John-boy states that they never saw nor heard from AJ Covington again. In fact, AJ Covington appears in two further episodes: The Abdication and The Achievement.
In this episode we learn that Zeb had a brother named Matt Walton who was a drifter. Cora Denby is Matt's daughter.
As the crowd gathers for Alvira's show, we see Ike enter the theater (his store) and talk to Grandpa, who's taking tickets near the door. In the next shot, we see Olivia and John talking, sitting on the front bench of the audience. Ike's head is visible in the row behind Olivia; he's turned and speaking to a Baldwin sister. The next shot is a wide shot of the audience, and it shows Ike just arriving, walking in front of Olivia and John and around to sit in that second row by the Baldwins.
When the father walks into the school room, he clearly writes the word REPENT in all caps on the board. If you look carefully, it is still the original "REPENT" from the far camera angle, but when it switches to the zoom-in on the teacher, you can tell the word has been rewritten. For example, notice the first "E" is now smaller.
John-boy's trip to Wheeling marks the first time any of the action has taken place outside Virginia. No further action will take place outside the state until The Inferno (5x20).
Jim Bob does not appear in this episode, making this the first hour not to feature all the main Walton characters.
Ellen Corby, who plays Esther Walton, wrote the story for this episode. At the barn dance, Esther is shown dancing with a man named Fred Hansen. Hansen was Ellen's maiden name.
Olivia serves Jody cookies in a bowl, but his close-ups show the cookies on a plate.
In this episode, Olivia tells Esther that all her children were born healthy. This will be contradicted later in the series when we find out that Jim-Bob in fact had a twin who died at birth.
This is the only episode to date that doesn't end with the exterior of the Walton house and the family members telling each other goodnight.
The closing narration has John-Boy mentioning Mary Ellen is married to a college professor. In truth, she married a doctor and a veterinarian through the course of the series and reunion movies.
Correction - Mary Ellen's 2nd husband Jonesy, was a professor at Boatwright University :)
When Jason and Ben are teasing Jim-Bob and Porthos (the guinea pig) about where they are going to sleep, they tell Jim-Bob he can sleep in the barn with Chance. Chance died in season 2's "The Graduation".
This is the second time Nancy Madden has appeared. Her first appearance came in The Star, when she and Ben took part in a spelling bee.
When John and Ben drive into the Maddens' yard (at 43:41) a crew member in a bright orange jacket and cap can clearly be seen ducking behind an old van.
Cleavon Little, who plays the titular fighter, appeared as Rev Hawthorn Dooley in both The Homecoming and The Fire.
A.J. Covington appears again, though the narrative that concluded "The Literary Man" indicated he was never heard from again.
When Wade is in jail, John refers to him as Boon's nephew, yet in 'The Conflict' (3x01) Boon refers to Wade as his grandson.
