Crazy theory time – what if this is the work of Benny to make it look like III? That way, Four will (hopefully) come to the rescue and bring Addison with her. We know how Benny wants Addison back.

“The greatest trick the Devil ever pulled was convincing the world he didn’t exist”. Is Benny our Devil?
