Deanna and John are amazing - this wasn't even what they are paid to do: from getting into the mind of the killer, to recognizing his writing patterns, to forensic image analysis, to gleaning clues from his movie co-opting... two people who never met each other, yet complemented each other while keeping step with this diabolical psychopath and helping to obliterate his attempt to create a phantom puppet master, ensuring he alone rightly bore the full weight of accountability.
