When Jupiter first showed up, she used a technique to manipulate the power of her Sableye's Shadow Sneak using her Tangrowth's Flash.
The curious thing is that after she used it, she called the technique an "interesting reaction."
This is curious because it was almost word-for-word the same thing Sird said about the Dex holder's petrifaction.
Later on, when Platinum battles Volkner, she flashes back to a scene of Jupiter being happy to have captured Uxie, since she hates cold places and can leave Lake Acuity. The curious thing here is that she was caressing her left leg, the same one that Lorelei froze on Sird.
Of course, people assumed Jupiter was Sird and vice-versa. Then volume 37 came out and put those theories to bed.
Now this was either some big red herring, or Kusaka decided to change things last minute.
And the thing on Jupiter's leg isn't a bandage, it's a leg warmer, because she hates the cold. Why she doesn't invest in some pants is anyone's guess.
