Molly Ringwald did not return to play the part she had played in the first season because her film career had created a scheduling conflict.
At the beginning of this episode, viewers assume that Jo never knew Nancy, Cindy, or Sue Ann. However, the Season 2 Episode 9 "Gossip" contradicts this with a scene with Jo sitting next to Blair at a table with Sue Ann, Nancy, and Cindy and talking with them, clearly indicating that she did know them and they knew her. Don't think this mistake went unnoticed; Tandem's office received dozens of letters.
This is Julie Ann Haddock's final acting job.
Charlotte Rae (Mrs. Garrett) can be seen in archive footage.
Julie Anne Haddock's character is referred to as Cindy Baker. In the early episodes, her name was Cindy Webster. She may have changed her last name due to her career as a model.
