In this episode, Karen tells new neighbors Gary and Val that her family, the Fairgates, are The Brady Bunch of the block and that they even have a dog. But this mystery dog is never seen in this episode or mentioned again throughout the entire series.
The opening title sequence for this episode is slightly different than from the opening sequence used throughout the first two seasons. It features shots of the actors superimposed over the houses where their characters. For the remainder of the first two seasons, the actors would be seen superimposed over the street.
Goof: On the parent series, Dallas, Lucy was engaged to lawyer Alan Beam concurrent with this episode. But she makes no mention to her parents about here engagement. Surely this would be huge news and one of the first things she would tell them.
The young girl gossiping at her locker is a very young Helen Hunt.
Gary calls his brother, Bobby, in Dallas, in a one-way phone call, to check up on Kristin's background, but Bobby doesn't reveal that Kristin shot J.R., because he didn't know. Consistent with her final appearance on Dallas (before this episode), Kristin reveals to Val that she is pregnant.
This is the only episode in which it is mentioned that Sid and Abby have a nephew named Paul Fairgate. The book, Knots Landing: Saga of Seaview Circle, lists Paul as Sid and Abby's older brother and their nephew as Paul Fairgate Jr.
The famous "Sliding Squares" opening sequence makes its debut with this episode, along with a new arrangement of the theme. The original version of the sequence would last until the end of the 1986-1987 season.
Even though Sid's death was due to an off-camera contract dispute, this episode started a classic Knots Landing trait used throughout the series. The "untimely death" that was a sudden surprise mid-season and not used as a cliffhanger. Knots Landing became known for some of the best mid-season cliff hangers ever written. Other examples include, but aren't limited to: Season 11 Episode 24 "Only Just Begun" when Pat was run over. Season 12 Episode 3 "God Will" when the last shot is a pan up through a swimming pool to Danny's lifeless body. And Season 13 Episode 3 "Eye of the Beholder" when Linda's throat was slit right before the closing credits.
This episode mirrored the real-life of Michele Lee who was going through a divorce from husband James Farentino. She and Farentino separated around the same time Lee's onscreen husband,Don Murray, left the show. Lee revealed that when her character took off her wedding ring in a 1982 episode, she was taking off her real wedding band as a symbol of moving forward.
Abby's copy of Val's manuscript shows the title of "Capricorn Crude" but Abby made her copy before this title was chosen
Toward the end of the episode, Lilimae joins Ciji and her band in the middle of the cul-de-sac to perform the song, "Will the Circle Be Unbroken," which was first sung on the show in Season 1, Episode 5 ("Will the Circle Be Unbroken") by Lilliemae.
John Pleshette makes his final regular appearance as Richard Avery in this episode. Pleshette later directed episodes and returned as Richard in Season 8
Kim Lankford and James Houghton depart the series with this episode. Lankford would return in "Back to the Cul-De-Sac."
The common belief amongst Knots Landing characters is that Chip killed Ciji. Curiously, neither Gary nor Laura appear to have any problem with Chip, even though they both cared greatly for Ciji.
Gary claims to never have discussed the subject of marriage with Abby. Yet in the previous episode, he introduced Abby as his fiancée to Greg Sumner.
Karen is found unconscious from drugs, in the bath tub, with water showering on her face.
This is similar to season 3 when Richard found the hooker, also unconscious from drugs, in the shower with water showering on her face.
Laura reveals in this episode, that she sold the restaurant, Daniel, which she and Richard opened in season 4.
After Gary's death, Val goes to the ranch to console Abby, who angrily tells Val that she's Gary's widow, not Val, and that Val is "nothing to him." Although they were divorced, Val is still the mother of Gary's firstborn (and up until this point) only child, Lucy. I think that qualifies as something.
I believe that Mack or Gary had called the Ewings in "Dallas" and told them of their ruse. In fact, Greg Sumner was suspicious enough to ask Karen in the next episode why the Ewings didn't attend Gary's funeral, which led Karen to discover that Mack had been lying about Gary's death.
Gary is believed dead but his mother and brothers did not come to the funeral?! Obviously there were production and financial problems in having everyone cross over from "Dallas" (or maybe they knew he wasn't really dead, as is alluded to in the next episode) but from here on the two series would have many problems both when they did cross over (Bobby's "death" which was Pam's dream) and when they should have crossed over like here and they didn't.
