This episode made me wonder why the ghost didn't do something more directly himself.  He seemed to be able to manipulate many people directly, but perhaps it was because the actor was already mad at the woman and he just built it up more.  Kind of strange how she sat where the mannequin had been previously.  Also, if the ghost could keep the lights from turning on, couldn't he have done something else to kill her?  Just questions that came to me.  I thought it was still an okay episode.
