Trivia

This is the first time Daniel and Bobby are in the same scene together since the first film.

The mailman arriving and delivering a note to Chozen from Kumiko is a direct reference to Karate Kid Part II (1986) from the dialogue from the mailman to the note from Kumiko's Aunt to Mr. Miyagi.

The dialogue spoken between the mailman and Chozen is identical to the dialogue between the mailman and Mr. Miyagi in Karate Kid 2.

co-creator Jon Hurwitz told TV Insider of Elizabeth Berkley's secret casting, "The idea of Chozen being on a double date with the LaRussos was fun for us, and we've alluded to Moon's mom several times over the course of the seasons. So this was finally our opportunity to bring her to life. And when we were putting together our list, Elizabeth Berkley was right at the top of the list. She was somebody that we were all fans of growing up. And we showed Billy [Zabka], who was directing that episode, our list, and immediately, he zeroed in on Elizabeth Berkley as well." "We were lucky that she happened to be a fan of the series," Hurwitz continued. "So when we reached out, she was on board right away." The scene, which takes place at a lush outdoor garden, was apparently shot on the final day of production for both Macchio and Henggeler in Atlanta.

Chozen is gardening at Miyagi-Do, which is symbolic, as he and his friends were the ones who destroyed Mr. Miyagi's garden in Karate Kid Part II (1986)
