Main Cast Edit

Supporting Cast Edit

Guest Cast Edit

  • John Duff as Twins' Alpha
  • Elise Robertson as Mrs. Raeken
  • Nadia Buer as Stephanie
  • Kevin Symons as Mr. Raeken
  • Claire Bryétt Andrew as Sydney (uncredited)

Continuity Edit

  • Tracy Stewart is the second person revealed to have been turned into a Chimera by the Dread Doctors, though she will be mistakenly believed to be a Werewolf until the end of Dreamcatchers and will not be officially referred to as a Chimera until Condition Terminal.
  • Ethan and Aiden were referenced by Theo Raeken. Ethan was last seen in The Divine Move, and Aiden was last seen in the form of a hallucination in Creatures of the Night.
  • Hayden Romero makes her first appearance as a childhood friend of Liam Dunbar and Mason Hewitt. It is also implied that Liam and Hayden have a negative history that dates back to the sixth grade.
  • Alan Deaton examines Belasko's talons and identifies them as belonging to a harpy eagle, the biggest bird of prey. In Condition Terminal, it will be revealed that they're actually from a Garuda, a mythological eagle shapeshifter from Hindu mythology.
    • Deaton also reveals that the only person who should be able to take a True Alpha's power is a Beta of their own making, suggesting Liam Dunbar is the only person who can take Scott McCall's power. This will come into play for the rest of Season 5A
  • Mason Hewitt finally learns the truth about Liam being a Werewolf and the supernatural world in general after he saw Liam wolf-out.
  • It is revealed that Theo Raeken can full-shift into a wolf in this episode. It will later be revealed in Status Asthmaticus that he can do this because he is a Werewolf/Werecoyote Chimera, and the Werecoyote ability to full-shift into a coyote merged with his Werewolf shapeshifting ability to allow him to fully transform into a wolf.
  • Malia Tate begins having flashbacks of the car crash that led to her accidentally killing her adoptive mother and sister, which seem to be triggered when she's driving in a car. The fact that Malia was in this car accident was first revealed in Anchors.
  • Liam and Stiles find a hole dug in the woods, which Liam falls into. This will continue to be important through the next few episodes.
  • Peter Hale and Derek Hale were mentioned by Scott and Stiles in this episode. They were both last seen in Smoke and Mirrors.

Trivia Edit

  • The title refers to "parasomnias," which does not just mean night terrors-- in reality, it is a medical term for an entire category of sleep disorders, some of which have already been referenced in the series. This category breaks down further into non-rapid eye movement (NREM) parasomnias and REM parasomnias.
    • The former category includes confusional arousals (awakening in a confused state), sleepwalking (also known as somnambulism), sleep/night terrors (like that experienced by Tracy Stewart in this episode), teeth grinding, restless legs syndrome, sleep sex, and sleep-related eating disorders.
    • The latter category includes REM sleep behavior disorder (during which the person acts out their dreams due to a lack of muscle atonia), recurrent isolated sleep paralysis (like Stiles Stilinski experienced while possessed by the Nogitsune), and catathrenia (breath-holding and expiratory groaning during sleep).
