So she bought the hotel back from him...interesting. Was that just so she could pull off that illusion, or does Akira get his money back from that?
I have to admit, as much as I hated her to the core the previous episodes, Shiratori was disturbingly likeable this episode. She knows damn well she is a murderer, was one before she became a Selacao (which gives her a lot of credibility and integrity because the money didn't change her at all), and quite frankly, she has her own individual charm, albeit a little creepy.
My guess is that the three illusions are the realistic wings, the supports (for her and the pervert floating), and the helicopter to blow out the windows and take her away.
