It's All About the Label
One episode of the season gives us a bit of backstory on Detective Samuels, played by Colton Haynes. In one particularly telling scene, Kai goes to the policeman's apartment to make a delivery. A few bottles of wine sit near a stereo, and among them is Michael David Winery's Freakshow Cabernet. Clearly, this was meant to be another (very subtle) nod to the show's fourth season.
