Maybe this has been noted somewhere else, but I haven’t seen it so I figured it was worth mentioning!
Ok so, when Usagi, Ami, and Makoto pass by the bridal shop on the way home, Ami says something specific to Makoto: the dress she is eyeing would look good on her because she is tall. The mannequin wearing the dress in question - the one known to the audience as controlled by Nephrite - is shown as taller than the other mannequins around her.
Later, when the mannequin attacks the Senshi, she barrages them with black rose petals.
And of course, Jupiter’s first attack is the gorgeous Flower Hurricane.
The rose attack with the mannequin could just be a part of the Bridal motif, but I think the height comparison makes it significant in a different way.
What if, in this iteration of the story, Nephrite’s “Shadow” is based on what some deep down part of him remembers of Sailor Jupiter?
