Who was Aozaki talking about when she said Ryougi? In movie 3, Aozaki is staring out the window and talking to herself after Shiki leaves. Who is she talking about when she says Ryougi, since she already called Shiki by name in the same sentence?


  Touko Aozaki: Shiki might end up being killed instead if she goes alone, Ryougi.


This happens at around 27:55.
One possible reason is that 


   Aozaki may know the existence of "the Void", another personality which never surfaced.


However I can't find evidence showing that Aozaki really knows about it.
