At one point in the episode, there is a billboard behind Naru which reads "SMSS Saturdays 7:00 PM."
This is the final episode in which Naru and Umino appeared. However, they did make an appearance in the special Sailor Moon Super S: Ami's First Love (1995).
Umino's facial expression at the end of the episode closely resembled Edvard Münch's "The Scream."
