Read it up on the wiki, the blue haired girl has something of a 'Return' powers, able to return anything into what they once were. Was hoping for some AR scenes from her and man did they deliver. Doubt it would go farther than say this specific scene. Pretty sure its a "Look what I can do, neat huh? Ok I'll turn you back".
Though since she is part of the villians crew she might AR someone she is fighting. Lets hope its Robin.
