## Continuity

* This episode marks the official introduction of the Skinwalkers, powerful indigenous American shapeshifters, after their first brief appearance in the previous episode.
* Scott learns that Theo Raeken resurrected Hayden in this episode, though he already knew about the resurrection of Tracy, Josh, and Corey. Hayden died and was resurrected by Theo in *Status Asthmaticus*.
* It is revealed that The Beast of Gevaudan was indeed resurrected by the Dread Doctors, but since they couldn't do so out of thin air, the last Chimera (and the only successful one) is acting as a vessel for it. The Beast was resurrected at some point prior to *Status Asthmaticus*, and was first mentioned in Season 1's *Heart Monitor*.
* Noshiko Yukimura informs Kira that as a result of the Dread Doctors' experimentation on her, Kira risks losing her human self forever if her inner Fox spirit becomes powerful enough to consume her. The Dread Doctors "jump-started" her Kitsune spirit in *Creatures of the Night*, and she discovered this was this case when she triggered her repressed memories by reading *The Dread Doctors* by Gabriel Valack in *Ouroboros*.
* Scott reveals to Stiles that he is certain that Malia is planning on killing her mother in this episode. This was first implied in *Lies of Omission* and was confirmed by Theo in *Status Asthmaticus*.
* Lydia and Meredith reference Gabriel Valack and how he used the audio recording of Lydia's Banshee scream to break out of Eichen House, which occurred in *A Novel Approach*.
	+ It is also confirmed by Meredith that when a Banshee's scream is given focus and direction, it can be used as a weapon, just like how Valack used it. This explains how Lydia was able to create concussive blasts with her voice and hands in the flashforwards in *Creatures of the Night*, and foreshadows the fact that Meredith will teach Lydia how to use her voice as a weapon in *The Sword and the Spirit*.
* Mason Hewitt and Corey kiss for the first time in this episode. They first met and showed an interest in each other in *Strange Frequencies*.
* Stiles finally tells Scott the entire story about how he accidentally killed Donovan Donati by trying to incapacitate him with the construction materials. Donovan was killed in *A Novel Approach*, and Scott first learned from Theo that Stiles killed him (albeit an incorrect version of the story) in *Lies of Omission*.
* A desert version of an Oni appears in this episode. The last time an Oni was seen was in *The Divine Move*, when the five Oni Noshiko summoned were all killed by Chris Argent, Derek Hale, and Ethan and Aiden.
* Mrs. Finch and Ms. Fleming appear in this episode. They were last seen in *Required Reading* and *Orphaned*, respectively.
* In a Banshee premonition experienced by Lydia and Meredith while using their telepathic connection to communicate, they appear at the library at the high school, where Lydia finds that all of their initials on the bookshelf from Senior Scribe have vanished as a foreshadowing of the possibility of everyone dying at the hands of the Beast. Scott, Kira, Lydia, Malia, and Stiles all inscribed their initials (along with Allison Argent's) on the bookshelf in *Creatures of the Night*.
* Kira tells Scott that she loves him for the first time in this episode. Scott first told Kira he loved her in *Condition Terminal*.
	+ Scott and Kira also reunite and kiss for the first time since Kira left Beacon Hills in *Ouroboros*.
* Deucalion was mentioned by Liam and Mason. He was last seen in *Lunar Ellipse* and last mentioned in *More Bad Than Good*.
* The Jeep has been more-or-less repaired by Stiles. It was last seen in *Status Asthmaticus*, when it was so broken down that Stiles had to have it towed.

## Trivia

* The episode title refers to Mrs. Finch's lesson on codominance in terms of genetics, where instead of dominant alleles overpowering recessive ones, they are both present, and sometimes even combine to make something new. This could be a reference to the Chimeras, or to the dual personality of The Beast of Gevaudan and its host, Kira and her inner Fox spirit, or Parrish and his Hellhound spirit.
* Scott and Stiles reference a serial killer known as the Demon Tailor during their research of the concept of *damnatio memoriae*. This killer is said to be a real person who brutally assaulted children, boiled them, and ate them during the late 16th century in France, and is also known as the Werewolf of Châlons. However, sources of information on this killer are not proven to be completely accurate.
* Shiprock, New Mexico, where Kira was seeking help from the Skinwalkers, is in Navajo Nation, a semi-autonomous territory in the southwestern United States that belongs to the Navajo tribe of Native/Indigenous Americans. This suggests that the Skinwalkers also belong to the Navajo tribe.
