Invader of the Opera Part 4

My fourth one. Lets say that Christene (Gaz) hears the Phantom's voice (Zim), until Meg Giry (Tak) came looking for Christene, to ask who is her tutor. Christene told her that her father (Prof. Membrane) told him about the Angel of Music and has come to her. Meg thought that something like that isn't true. Meanwhile, Raoul (Dib) will be seeing Christene alone.
