Dread Doctors, Theo Raeken, the return of Deucalion, the Beast of Gévaudan, the return of favorites like Chris Argent, coupled with dissent among the pack--season five has been one of change and it's been one hell of a ride.
Add in the possibly permanent return of Crystal Reed or at the very least, additional chapters in the life of the maid of Gévaudan and Allison Argent and the next (and sadly, final) season could be Teen Wolf's best. We can all sit on the edges of our seats until then, but while we're waiting, let's talk all things season five...by first revisiting season four, but just for a sec--I promise.
Season four ended with Derek turning into a black wolf (i.e. Tyler Hoechlin leaving the show after a fairly disjointed character journey for greener pastures in the form of the CW hit "Supergirl"). Jeff Davis and team could've done so much more with Hoechlin as Derek, and I hope we will get to see some more of that in the final season, but as season four ended, some important moments took place, moments that have affected season five in major ways. First of all, we were guaranteed the possibility of two excellent villains coming back to us in the form of Kate Argent and Peter Hale, both of whom are still alive and just waiting to wreak more havoc (*rubs hands together in glee*). Chris Argent's character develops a bond with the Calaveras family, who I think I speak for all of us when I say, we would most certainly like to see more of. Might the Calaveras be a mechanism to help control Peter Hale in season six (which by the way, actor Ian Bohen is confirmed to be returning for)?
The season four finale saw the pack save Scott after being turned into a berserker and turning on the pack, but the majority of season five also saw Scott's loyalty to the pack tested, starting with the introduction and eventual acceptance of a young man purporting to be Scott's fellow asthmatic childhood friend-turned-werewolf, Theo Raeken, and ending with the setup of Stiles to take the fall for a murder of a chimera who attacked him, which was actually a self-defense killing.
Not only does a rift form between Scott and Stiles, but Liam is pushed almost to the breaking point when he attempts to kill Scott after Hayden develops mercury poisoning due to experimentation and an eventual procedure performed by The Dread Doctors.
Fortunately, Scott and Liam work out their differences before they can kill one another while locked together on a magical kill floor/battle ring under the full moon at its perigee/syzygy.
But the betrayal doesn't stop there. Theo targets Malia, Kira and, as previously mentioned, Stiles, hoping to recruit the "darkest" members of Scott's pack while leaving Scott himself to Liam, eventually admitting that he wants void Stiles, the dark Kitsune and were-coyote Malia to join his pack of supernatural genetic chimeras working for the Dread Doctors.
This scene really tells us all we need to know about narcissistic sociopath, Theo
That leads us to the Dread Doctors, who start out as characters in a book written by fellow supernatural creature, Dr. Gabriel Valack, who is being held at Eichen House with Peter Hale, and who become very real villains. The Dread Doctors are immortal specialists who have staved off death, making themselves nearly unkillable and who exist on a different vibrational wavelength. The aptly named "Dread Doctors" can manipulate time, electromagnetic frequencies, electricity and various elements of the dimensions they inhabit, including the dimensions themselves, moving through them with apparent ease. Their goal is to find teenagers who are genetic Chimeras who they then turn (through supernatural surgical procedures) into monsters. The catch is that most of these teens have to die first, before they can be "reborn" as monsters.
The Dread Doctors, hard at work being dreadful
Newest werewolf and new addition to the pack, Liam Dunbar, finds out that the Dread Doctors are after Hayden Romero, kidney transplant survivor, former grade school frenemy and current crush. Hayden works a night job to help to pay for the anti-rejection medication she takes so that her sister, Deputy Clark doesn't have to do it all on her own. After doing everything he can to save the already very capable Hayden from the Dread Doctors, she is captured and transformed from a human genetic chimera into a supernatural chimera, dying and being reborn in the process. But rather than staying with Theo Rayken's pack, Hayden's developing feelings for Liam prompt her to join Scott's pack.
Theo, who has been working with the Dread Doctors long term--since he killed his sister, as a child, in order to become something the Dread Doctors can use, in fact, quickly becomes disenchanted with the Dread Doctors once he realizes that he's not their ultimate creation and that he has little to do with their endgame of resurrecting the Beast Of Gévaudan through another as yet unknown genetic chimera who happens to be close to Scott's pack. Unfortunately for Theo, the Dread Doctors are just as disenchanted with him, forcing Theo to turn to other means to consolidate his power.
Desperate and exposed to Scott and his pack for the sociopathic bottom feeder that he is, Theo makes a deal with a previous villain in order to shore up his remaining pack and his waning power. Theo calls on Deucalion, the ostensibly blind demon wolf to take down Scott McCall's pack so that Deucalion can steal Scott's eyes. As Theo's pack dissolves, Theo begins stealing energy from his remaining pack members before killing them, leaving Deucalion, whom he is holding as a quasi-prisoner to manipulate the remaining members of his pack and in the end, to manipulate Theo himself.
Once the Beast manifests itself, Scott and his pack find that its alter ego is an otherwise unaware human genetic chimera who morphs into the Beast, losing their own identity in the process. As the Beast changes more frequently, that human becomes lost and the Beast remembers who it used to be as a human before it was killed hundreds of years ago by The Maid Of Gévaudan. Time is running out for the pack and for the Beast's thus far unaware human alter ego, leading Scott's and Theo's packs to briefly work together to try to stop the Beast, whose alter ego, the pack finds out with the help of some friends, allies and even a couple of enemies is none other than Liam's best friend, Mason!
At the beginning of the season, we jump ahead in time to see that Lydia is being held captive by Dr. Gabriel Valack in Eichen House to be experimented on. Her powers have grown exponentially and she must fight her own inner demons in order to find her way out of her head and back to mental health so that she can help her friends. The two packs work together to free Lydia, Scott's pack, so that they can rescue their friend and Theo's so that they can steal hellhound, Jordan Parrish, whose fiery alter ego has been trying to save Beacon Hills by hiding bodies with the Nemeton. Theo's pack realizes that anywhere Lydia is, Jordan Parrish will be and it is soon found out that the hellhound/Parrish is prophesied to fight and destroy the Beast of Gévaudan. This information comes to light after Jordan Parrish is questioned by Chris Argent and his newly restored Father, Gerard (who, lets be honest, we all know is just waiting for the right opportunity to turn on the pack). While the fight with the Beast is brewing, however, Scott's pack faces yet more individual problems and challenges as Kira and Malia have to face some of their own demons.
Kira goes with her Mom (but not before the Dread Doctors find her and experiment on her to increase her power!) to find a group of skin walkers living out in the desert that can help her control the kitsune within her, but at quite a cost. These skin walkers need Kira to live with them, perhaps indefinitely, until she wins the battle against her inner kitsune. Scott rescues her, however, before she is ready and Kira comes to an agreement with the skin walkers that she will return, staying in the outside world only long enough to fight the final battle with the Beast.
Sadly, Malia's Mother sees her as a parasite that grew inside of her and stole what made her special. Despite Talia Hale trying to help her, the Desert Wolf goes rogue and is out for her daughter's blood.
As the Beast of Gévaudan finally takes control over Mason, it becomes the man of Gévaudan--an evil and sociopathic individual brought back from 18th century France named Sebastian Valet.
Using Mason's memories, Valet quickly figures out how to fit in in 21st century America, endangering many, including the entire town of Beacon Hills and Sheriff Stilinski in particular when he arrives at the sheriff's office to pump them for information and make grand threats. Valet plans to decimate Scott's pack and take the entire town of Beacon Hills, getting back to his old, evil ways as a serial killer with a voracious appetite for destruction, assisted by one of the Dread Doctors who, in his original incarnation, was a friend of Valet's and of Valet's sister, Marie Jean, The Maid Of Gévaudan, who turns out to be the matriarch of the Argent family and an almost perfect genetic blueprint of eventual descendant Allison Argent.
After much excitement and, sadly, the eventual death of Marcel, the Beast finally faces off with Scott, but when he goes in for the kill, inserting his werewolf claws into Scott's neck, the man of Gévaudan hesitates after seeing a vision of Allison Argent in Scott's mind. This gives him pause and allows Scott to slip away, thus ensuring that Allison is able to save Scott McCall's life one last time, even in death.
Lydia has of course been rescued and restored to enough health for her to scream Mason's name with her newly expanded banshee powers, calling him back to his true self and separating him from le bête/the Beast and the Man of Gévaudan.
Lydia's banshee scream rips Mason free of The Beast
As Mason and Corey are reunited, the Argents rush Jordan Parrish to the underground tunnels used by the Dread Doctors where the final battle is taking place. Parrish flames on and becomes his hellhound alter ego and with the help of the Argents and Scott McCall, he uses a secret weapon (the silver rod that sneaky Gerard Argent has been using as a cane, which turns out to be the weapon that originally killed Le Bète/The Beast of Gevaudan) to kill the Beast.
As events play out, it is revealed that Deucalion and Scott McCall are now allies and that Deucalion, who had originally told Theo Raeken that he wanted Scott's eyes to cure his blindness has been able to see all along. Deucalion admires Scott for being a True Alpha and Scott admires Deucalion in return.
They share a mutual respect. Upon finding this out, Theo is angry and Gerard Argent tries to exploit his son's potential anger over this "betrayal" only to find that Chris has known all along and that Scott and Chris are planning to turn on Gerard, who, let's be honest, would have turned on them the first chance he got.
Deucalion doesn't come out of this episode without a few bumps and bruises. Possible karmic payback for all of his previous shenanigans? You be the judge. Will this be the last we see of the demon wolf? We sure hope not.
And as far as just desserts are concerned, Deucalion isn't the only one to suffer a few well earned bumps and bruises. Theo finally gets what's coming to him in the form of his deceased sister, called from beyond the grave to snatch him into the earth, courtesy of Kira and the skin-walkers, who Kira has of course made a deal with to return to the desert to finish her studies with the tribe, which may take quite a long time. Thankfully, Kira is basically an immortal creature in her own right.
Not all of the romantic reunions in "Apotheosis," the final episode of season five end without a price having been paid. Hayden is injured in the fight and Liam must bring her to Dr. Deacon who doesn't hold much hope for a natural recovery. The only option is for Hayden to become a werewolf. The choice is left up to Hayden and ultimately she chooses the bite, holding Liam's hand throughout the process. Scott obliges and in the final scene of the final episode of season five, part two, we see Liam and Hayden out together on the night of the full moon as werewolves, making Hayden the newest fully fledged member of the McCall Pack.
