For the last Tread Perilously of 2016, we reopen the case files of the Special Review Unit for an episode of Law Order: Criminal Intent called "Faith." A seemingly apt title.

Det. Robert Goren and Det. Alex Eames investigate the murder of a man helping Erica Windermere, a young author hiding from her dope gang parents. She's written a book, Through The Darkness, about her struggles with Lou Gehrig's Disease and her early abuse by her drug gang parents. Erica's editor can only offer her email address as contact information. And when Erica responds to Eames' email, Goren asks a most important question: "How has your disease affected your menstruation?" From her answer, he comes to believe that she does not exist.

Executive ADA Louis Allred joins the Special Review Unit once again as Justin meets Det. Goren for the first time. He also learns about the new La Croix Sparkling Water rule for white people. The SRU ends up talking about Taylor Swift. Several respirators are purchased. Doctor What appears to refill a drink and the discussion wanders into another look at Gone Girl. Also, Justin declares that Vincent D'Onofrio is a bad actor, Michael Nouri gets a name check, and Erik's D'Onofrio impression lapses into William Shatner.
