This episode resolved the subplot of Ami and Naru's animosity, which has no basis in the anime or manga. It also introduced a new subplot, about a girl who Usagi believes is Mamoru's girlfriend, which has no basis in the anime or manga. Jadeite is returned to his human form, an event which has no basis in the anime or manga. Finally, the revival of Queen Metaria begins, which was handled very differently in both the anime and manga, where Queen Metaria already existed as a sort of noncorporeal mass that Queen Beryl could talk to.

This is a great episode. A great episode that has no basis in the anime or manga.
