Simon says : ''Be naughty!''
Reading an interesting review of the movie (thegirlwholoveshorror)I came across very interesting take on the plot.
''Session 9 is different. It's not the haunted mental asylum ghost movie where the characters have to figure out the mystery of the ghosts or whatever. This isn't really a spoiler, but the movie is not about the hospital or the multiple personality patient, Mary Hobbes, as one might think. The session tapes that Mike starts listening to serve as a mirror to the real problem going on under the surface of these men's personalities.''
Since it is relatively easy to figure out Gordon is the problem... ''Why then all the crap about Mary Hobbes and her freaky ass vocal talents? Let's analyze this part of the story, shall we? Watch out for spoilers here.''
''Okay, so Mary was this little girl who killed her brother, Peter, and her parents. She was told to do so by one of her personalities, Simon, after her brother scared her and made her drop her new china doll. She was committed to Danvers and a doctor with a very creepy voice records his sessions with her as he tries to bring out her other personalities to find out what really happened that day. Princess is the innocent little girl, Billy is Mary's protector, and Simon, of course, is the bad one - AN EXTREMELY MALEVOLENT VERSION OF THE ID.''
''Mary's story, therefore, parallels Gordon's story. Gordon is Mary, Mike is Billy, Jeff is Princess, Hank is Peter, and Phil is the doctor.'' - I cant say I agree with this but it is interesting.
''As Simon's last line tells us, he "lives in the weak and wounded." What I think this means is that he is that part of all of us that can lash out when pushed too far, or the part of us that we always repress that is capable of real damage to those around us. He tells us to do bad things ("Simon says") and the weak and the wounded are the ones who are not able to stop him from rising up.'' - This part is spot on, and to add, PTSD (Post Traumatic Stess Disorder), especially in the childhood, has a definite link, if not being the major cause of DID (known better as Multiple Personality Disorder)...
