[1] Teen Wolf is a supernatural drama series that follows Scott McCall (Tyler Posey), a high school student and social outcast who is bitten by a werewolf.
At Season 3B end, after Allison's death, Deaton provides counsel for Scott with the fallacy "Regression to the Mean", saying things will stop being all bad, or all good and always revert to a neutral space.
In "The Last Chimera", when Lydia is rendered catatonic, Natalie is distressed and out of fear for her daughter's life, angrily refuses to allow Stiles to see her, blaming him and her friends for her state of mind.
In "The Sword and the Spirit", Natalie maintains her belief that Lydia is save at Eichen House and that she is being prepped for legal and medical electroshock therapy, in spite of Stiles' protests.
Marin lets Stiles know if the burns disappear completely, the Nogitsune returns and Scott and Deaton haven't found a cure by then, she will kill him by lethal injection to do what she does: "maintain the balance".
In Season 3B, they've lost their Alpha status and their talent to merge into their super-werewolf form in their feat to survive Jennifer's attack, so they disappear for a couple of weeks, with Ethan breaking up with Danny, though Lydia keeps in contact with Aiden.
She could use telekinesis, a form of mind control to have a pianist killed by a split random cord off the piano to slit her throat for her final Philosopher sacrifice, she could appear somewhere else partially or teleport completely as seen when Lydia saw her materialize in a blaze in "Motel California" and when she abducted victims.
Overall, her most impressive ability was glamoring herself to hide in plain sight so efficiently she settled into her "Jennifer Blake" persona for the majority of the time fooling many people she was a harmless, innocent woman.
Cora became friends with Boyd during their imprisonment, but the hecatolite lined in the bank vault refracted the moonlight, refraining the two werewolves from fully transforming during the full moons, causing their rage and bloodlust to build up inside.
During Season 3B, Cora goes into hiding at Derek's request, remaining in South America as he undertakes a mission to retrieve their mother Talia's claws from the Calavera hunters and they separate.
While Braeden is shown to be fearless, spontaneous and altruistic, it is explained she is a mercenary for hire, taking dangerous jobs from anyone who can pay her, regardless of her client's intentions or identity, or the moral compunctions of her missions.
With her lessons for Derek in hand-to-hand combat and firearms paying off, both are able to fight off the assassins both at the school, saving Scott, Malia and Liam's lives, and at the Argent Arms International warehouse when protecting Satomi's Pack.
Out of injustice, Noshiko prayed for her ancestors to send a Nogitsune to punish those responsible for the massacre, intending for the Dark Kitsune to possess her, for her pain and misery to imbue him with power.
In Season 4, during the Dead Pool situation, in "Time of Death", Noshiko shows Kira how to use her Thunder Foxfire to incapacitate Scott into a vegetative as part of a plan to catch the Benefactor.
Noshiko attempts to assist Kira in bringing the sway of her power back to her human side, but she and Ken see their daughter has left into the night, going into a fugue state.
The Guardian of the supernatural awakens and communicates with Lydia: Parrish himself is an avatar for the hellhound to function, who was born by the Nemeton's power around the same time Scott, Stiles and Allison committed their sacrifice.
She responds it means 'the truth' that werewolves are inherently violent creatures cannot be denied in reflection of her loss of control that led to Rhys' death seventy years previously.
She is a philosophical and disciplined individual having mastered her inherent rage as a Bitten werewolf, admits her kind are violent creatures but she will kill if it means self-defense or protecting her Pack from harm.
If Lydia were to find the teenage Chimera that acts as the Beast's host, her powers at that point will surely kill her, but placates that it may end up saving her friends' lives.
Ever deceptive and self-serving, Theo takes command of his Pack, devising ways to help them develop and control their abilities, feeding them false promises only he can keep them safe when in truth dominating them, having them turn into killers.
Immediately afterwards, he kills Josh to absorb the latter's electrical power, allowing him to wear the Mask to track down the Beast, seeing its true human – Sebastien Valet.
They hold a Nazi Alpha werewolf known as "Der Soldat" (German for "The Soldier") who fought in WWII in a large green tube whose blood provides them with a serum with rejuvenating properties to restore their health and prolong their lifespans.
Back in grade school, Liam had accidentally backhanded Hayden's face during a fight he had with another boy on year book picture day as collateral damage, for which earned she bears him a grudge.
After Liam shows her his Wolf face, his rescuing her from the Dread Doctors, brought to Scott's Pack and then being horrified at seeing her own werewolf features, she answers them: "I believe you".
Theo finds the supernatural tree, then using the blood of the Dread Doctors' incubated Alpha werewolf "Der Soldat", he revives Hayden along with Corey, Tracy Stewart and Josh Diaz, bringing them back to life.
Tracy prevents Malia and Braden from participating in final showdown against the Beast by breaking their mountain ash seal allowing the Desert Wolf to enter the McCall house and leaves them to die at the assassin's hands.
Corey is found to be attached to many wires in the radio room of the phantom train station and acts as the link to merging the Ghost Riders' limbo with Beacon Hills.
Corinne moves in to make the killing blow, but Deaton gets free of his gag and yells out to the assassin that she can't get her lost power back from Malia except whilst on a full moon, otherwise she gets nothing, stalling her.
She recalls, years ago, Talia Hale's persistent attempts trying to make her realize the gift of childbirth whilst she was pregnant with Malia, and her seeing the beauty of a werecoyote passing part of her power to her child.
Having killed close to 500 people, Sebastien Valet is a born monster, arrogant, diabolical, vain and boasting of his immense power, entitled in being the "famous and feared Beast of Gévaudan".
