She's standing on top of the girl whose legs she's holding right

Okay SO... she's wearing a decoy boob shirt and holding decoy legs to throw off her enemies.  That or those are other people's body parts that she's stolen for her dark rituals... or custom body pillows she's holding while she listens to angry music and complains that her parents don't understand her.
