Personally I think Purefoy is what'll keep this show going. The story is to be a form of living art where his cultish followers are out doing his bidding through various means of widespread killing and insanity.
Now that Joe Carroll is out he has a plan to force Ryan Hardy into being a hero in his 'story.' During Purefoy's time in prison, he somehow managed to amass a large cult following. Well, Purefoy escapes and Bacon is brought back to help capture him again.
Purefoy's Poe-obsessed professor turned serial killer was put away for murdering 14 people almost a decade earlier by Kevin Bacon.
