Trivia: At around 5 mins 11 seconds into the episode, Vincent Nigel-Murrey and Dr. Saroyan are discussing the bones on the forensic platform. In the background of a shot of Vincent, the x-ray on the screen is of Homer Simpson's head in the middle of the screen, instead of a real human skull.
Trivia: Most of Catalina's speeches in Spanish (the ones that are not translated) are actually actress Nadine Velasquez speaking to the camera, addressing the viewers. For example, in episode 1-11 (Barn Burner), although it appears that she is throwing insults at Joy, she is actually saying "I want to take this moment to thank our Latino audience for watching. And for those of you who can understand me but who are not Latino, I want to commend you for learning a second language".
Trivia: Christina is thrown out of her house after the revelation that she's been lying about her life, and leaves town on a Greyhound as the camera pans down to reveal a sign saying "Now leaving Point Pleasant. Please come back soon.". This is almost identical (both the shot of the sign and the story behind it) to the Buffy The Vampire Slayer episode "Becoming" (2x21) - both the show's executive producer (Marti Noxon) and the writer of this episode (Diego Gutierrez) are former BtVS writers.
Trivia: Season 4 - Episode 4 "Thirteen"; The episode revolves around a man killing people with the same first names as the thirteen apostles (Mary Magdalene being the 13th), and killing them in a similar fashion in which the apostles died. At one point, Colby and David find a box with a mannequin's head in it. This is a reference to the film Se7en, in which seven people are killed for committing one of the seven deadly sins. The film ends with the main characters finding an actual head in a box.
