More to it

They were all personalities. In the beginning the doctor is crossing out "Personality 13" and "Personality 12". We don't get the names of the hotel owner or the cop, but the doctors were already taking measures to wipe out the personalities. Only 11 remained to meet at the hotel. Anyone who interacted in the mind of Malcolm Rivers were personalities he created. After seeing the movie, you kind of need to watch the beginning again to hear the tapes the doctor listens to, see the articles the doctor is reading and see his notes. This movie had more twists than anyone was prepared to comprehend. You would also notice Malcolm's mother's name was Callie, possibly leading to his use of state names for everyone else. Watch and see if there is any way to get the name of the cop transporting Rhodes and Maines, the original hotel owner prior to Washington's take over of the hotel or Paris' so-called client with whip cream on his chest. More states are represented within their names if you pay attention. Maybe there was an Alaska Nebraska somewhere or Hawaii Connecticut. Who knows.
