Poor Venus suffered a broken neck too in Act 11:
Actually, the page preceding this one has an error as well. Really, the entire scene seems a bit confused:
It all begins when Evil!Mamoru hypnotizes Makoto. Hypnotized!Makoto then lures the other girls to their secret control room underneath Crown Arcade. Usagi takes off her Silver Crystal pendant to show Makoto that it's safe. Makoto reaches out to grab it, but Minako, sensing Makoto has been possessed, drop kicks her. Since Makoto did not grab the Silver Crystal, Usagi is still holding it.
Minako tells everyone to transform, but we only see her do so (even though group transformations are customarily shown; in fact, Sailor Mercury doesn't appear until seven pages later, then only in a single panel, and Sailor Mars doesn't appear at all, so the chapter basically becomes the Moon and Venus show at this point). Hypnotized!Motoki then lunges at Usagi to grab the Silver Crystal from her. (Actually, it's not clear based on the panel art if he's lunging at her to get the crystal, or if he's blasting her with an energy attack.)
Venus again intervenes by attacking Motoki with a "Sailor V Kick" followed by a "Venus Love-Me Chain." We see Venus clearly holding her Venus Chain / Whip of Love with both hands in the first panel of the aforementioned page. In the next panel, she's suddenly holding the Silver Crystal. (When did she take it from Usagi?) Then, at the bottom of the page, she is again holding her Whip with both hands, no Silver Crystal pendant chain in sight.
First it was her gloves, now it's the Silver Crystal... Why can't Minako keep track of her stuff?
