Joanna Barnes plays Glen's girlfriend, Monica. She is very much like the role Barnes played in the Disney film, "The Parent Trap." The film also featured actress Cathleen Nesbitt.
This episode was clearly filmed early on in the season despite it airing at the very end of Season 1. First, Katy's hair is pinned up. By the end of Season 1 she was wearing it down. Second, Mr. Cooper's character had been phased out and suddenly he shows up. 3) Katy clearly acts like she and Glen are still uncomfortable with each other when, by the end of the season, they have already kissed several times. 4) An episode that aired before this episode clearly had Glen say he was going to marry Katy when the time was right.
