In episodes 39 and 40, learn how the demonic SA of Jack and Janet Smurl was a huge part of the allegedly true story of the Smurl haunting as discussed at length in interviews and in the book The Haunted (the allegedly true story of the Smurls, written with the Warrens). I assure you they didn't leave it out of the Conjuring Last Rites out of respect for the topic or family as they wrote about it in inappropriately disrespectful and pornographic detail in the book. They left it out because the Smurl haunting is the bottom of the barrel of the Warrens' paranormal cases and they needed one last "true" story from their canon before they launch their newest spinoff Conjuring series. SA isn't something to be used as a marketing ploy for selling more books or securing a movie deal (which is what Ed Warren did).
