Unlike Rei and Ami's cameos, Makoto is the first Sailor Guardian to speak in her cameo appearance.
This is the first time in the Sailor Moon anime where a Sailor Guardians' transformation sequence is interrupted (with Sailor Moon realizing she doesn't have her tiara).
Sailor Moon uses Moon Twilight Flash to defeat the shadow of Nephrite in this episode, a move that she does not use in the original series. In addition, the original Japanese dub didn't have Sailor Moon say her Moon Twilight Flash attack and instead say her "In the Name of the Moon, I'll punish you" catchphrase. However, the Viz Media English dub had Sailor Moon say the name of the attack.
The manga Usagi had fallen asleep reading was Prism Time, another one of Naoko Takeuchi's works.
