Answer 1

Barry, a flamboyant fashion expert, is Kevin's dominant personality.When Barry's control on the group starts to wane, Kevin's dark side mutinies and he becomes lethal. Dennis has Obsessive-Compulsive Disorder, partly a nervous attempt to control his deviant sexual impulses, which include a desire to watch young girls dance naked. He is mostly subservient to the more dominant Patricia. Patricia seems to be a middle to upper class older woman, smartly dressed and softly spoken, though clearly mentally unstable. She is instrumental in welcoming The Beast, convincing more malleable personalities like Dennis and Hedwig to do her bidding.
