Who was it that held the "internal" monologue in chapter 15's pages 5-6? Was it Fujimura or Eriko? Who was scolding who afterwards? It was very confusing, very meta.
I thought it was clear that Eri made up the entire monologue, but she was trying to pass it off as Fujimura's. Notice that the monologue started when Eri declared her ability for delusions, and it somehow ended up with Fujimura wanting to take a bath with her, something the real Fujimura will never declare.
