Okay, my self-control is just about gone. I had a lengthy entry in mind that boiled down to how you can track the level of the Dean's control over Perry in Season 2 through costuming. I'm also wondering, since in the Season 2 finale the Dean specifically mentions having to find "alternate accomodations" after getting shoved into the pit, does this mean Perry has been unknowingly possessed since the last episodes of Season 1? She doesn't show any signs of it during the Christmas Special, which raises the possibility that the Dean could only be in control while at the Silas campus. If our heroes had managed to stay away from Silas University, would the Dean have been forced to remain dormant?
