"Vanishing twin syndrome...?" Deaton asks Stiles who had brought Masons medical files which had been given to him by Melissa. "This is part of your expertise, right?" Stiles asks Deaton with hope in his voice. "Not particularly, no." Deaton answers warily. Stiles frowns in disappointment as Deaton studies the chart. Just then, a loud noise is heard as Jules Liam and Scott appear in the doorway, holding up an injured Dread Doctor.
"He's still alive!" Scott says as he lays The Doctor on the exam table. Jules, Deaton, Scott and Liam surround him, looking concerned. " Can you keep him alive?" Scott asks Deaton. " I'm not sure he technically is alive." Deaton answers him as Liam scoffs. "Screw keeping him alive! How do we get him to talk?" Liam asks him.
"Personally, I don't think we utilize torture nearly enough..." Stiles says which makes Deaton give him a look. Suddenly Liam turns his head. "Liam frowns and looks at the others. "Did you hear that?" He asks the group which makes Jules frown as she focuses her hearing as a voice calls out. "Come to me...To me..." The voice says when suddenly The Dread Doctor bolts upright and legs out an ear-splitting noise making the group cover their ears with their hands.
The Doctor soon turns and causes an electromagnetic blast that shoves Liam backward into the wall behind him before he crashes to the floor. He walks out the door and raises his hand before he walks into the parking lot, which causes all of the metal furniture to fly toward the door to the exam room. Jules helps Liam up and they along with Scott try to chase after The Doctor but Deaton stops them before they can.
"Stop. It's electrified." He says which makes Jules' eyes widen in shock. They decide to listen on what was going on outside and what they heard shocked them. The Doctor had fallen to his knees as Sebastian approaches him. He takes the mask off to reveal a withered old man with blood pouring from his mouth. Sebastian realized it was Marcel, a friend from the 8th century. "Marcel...if this is what immortality looks like, I think you might have been misled." Sebastian says to him. "For you...all for you..." Marcel tells him. "What did you do with it, Marcel? Where's the pike?" Sebastian asks Marcel who seems to have trouble breathing. "The Argents..." Marcel says which makes Jules' eyes widen. "The Argents...the cane!" Scott says as Liam looks at him with a defeated look. "But they took it. They took the cane." Liam says which cause the group to gather around gathered around the table where Scott began flipping through the pages of Masons medical files.
"Maybe there's something in here? Something about how he was a genetic chimera. Mason had a vanishing twin..." Scott reads aloud to the group." Now we've got a vanishing Mason." Stiles says. "What does that have to do with him turning into a 250-year-old French guy? How does that even happen?" Liam asks with confusion laced into his voice when suddenly Deaton gets and idea.
"Hold on... Scott might have something. Mason's twin wasn't entirely gone--that's what made him a genetic chimera. The DNA was still there. Metaphorically speaking, the DNA of Mason could still be inside Sebastien as well." Deaton explains to them leaving the group confused.
"How?"
"Life is energy. Energy doesn't just disappear. The Dread Doctors may have found a way to break the rules of the supernatural world, but there are some rules that simply won't break." Deaton says as Liam and Jules' faces fill with hopeful expressions. "So, Mason just can't be gone?" Liam asks him. "Somewhere in Sebastien, he has to still exist in some form. A spark of energy, a flicker of memory..."Deaton answers him.
"Hang on... Liam, you said Mason said something right before he turned." Stiles asks Liam which catches his attention. "He said..."That's not my name." Liam answers him. "He finally remembered his name." Scott says shocked. "Damnatio memoriae." Stiles says. "That's what they wanted. They wanted Sebastien to remember his name." Scott says in realization as Deaton smiles.
"Scott, you know the myth of what happens when you call a werewolf by its given name?" Deaton asks him. "It turns back to human..." Scott says stunned which leaves Jules and Liam confused. "What does that mean? Someone can just walk up to the Beast, yell Mason's name, and turn him back?" Jules asks the group. "Not someone..." Scott tells them as Stiles smiles.
"Lydia."
***
The group was hopeful at first, but when they got a call from Melissa telling them that Lydia was in the hospital because of Sebastien they immensely could feel their moods sadden. Currently Jules sat in a hospital chair, leaning her head in Bretts shoulder. He had gotten to the hospital after she had called him and explained the situation.
Liam sat one seat away from them and seemed to be lost in his thoughts until Scott walks up to them. "Is she okay?" Jules asks as Scott nods weakly. "She's gonna be fine, but... she can't really talk." Scott says which causes Jules to sigh and lean her head back with closed eyes. "Then its over, isn't it? There's nothing we can do to save him." Liam asks as Scott looks at him heartbroken. Just then Scott receives a notification on his phone and when he pulls it out he sees Kira's name. "Give me a second." He says to the group as he walks off. "Hey, it's me. Oh, God, I wish you'd just picked up. I hate leaving messages. I always ramble, I always say stupid things, and when I finally get to the super important thing that I'm supposed to say, the voicemail cuts me off, and-" The voicemail beeps and cuts off, and Scott begins to laugh a bit before he clicks on the second voicemail.
"Me again. I have to leave. But I'm coming back to help, I promise. Because you're right, Scott... if anyone's going to save Mason, it's you. It's us."
The voicemail cuts off, and Scott, now with renewed spirit after Kira's motivational voicemail, turns and walks back over to the group with a determined smile. "Get up." He tells them. "Why?" Liam asks in confusion. "Because I've got an idea... And because this isn't over."
***
The group walks to Lydias room and gather around her bed. After a moment, Melissa walks in, looking nervous and with a syringe concealed discretely in her hand. "Lydia, this is gonna have to be just between us, since I can get fired for it." Melissa says as Lydia nods in agreement. "It's a cortisone shot. It's gonna bring the inflammation down."Scott explains which makes Lydia hold out her arm towards Melissa, however she shaker her head at this. "Not there." Melissa reaches up and gently peels half of the bandage over her throat away so she can see the claw wounds. Lydia groans in pain, and Stiles and Liam begun to look woozy.
"Uh, yeah, okay, I'm gonna need to leave-." Melissa cuts him off as he starts to walk toward the door. "You're not going anywhere. Hold her hand." She says making Stiles sighs as he walks back to Lydia's bedside and hold her hand. "Okay, fine. I'm not leaving...but I still might faint."
Melissa takes a deep breath and uncaps the syringe preparing to stick it in Lydias wound. "Okay, here we go. Lydia braces herself, but before Melissa can do anything, Liam's eyes roll back into his head and he faints, collapsing onto the ground in a heap. Brett rolls his eyes at this while Jules check on Liam. "Okay, Lydia, this is gonna hurt like a bitch..."Melissa says as she pushes the needle into Lydia's neck, and she gasps in pain and whimpers as she is injected with the cortisone.
The group then begins to walk to the elevators while Stiles helps Lydia stay on her feet. The elevator soon takes them to ground level but needing to split up Stiles hands Lydia over to Liam and Brett who help hold the girl up. "Okay, I'll get Malia. Text me when you find Parrish." Stiles tells Scott as he begins to walk off. "Hold on--." Scott yells out pulling a cylinder shaped object that was wrapped in brown paper and throwing it to him.
"What is this?" Stiles asks him. "Something I've been working on for a while. Just make sure Malia gets it."Scott says leaving Stiles confused. "Is it Plan B?"
"It was Plan A..."
"Plan A never works." Stiles tells Scott. "This one will" Scott tells him warily.
***
Jules, Brett, Scott, Liam, and Lydia are walking through the tunnels in search of the Beast when they hear yelling and grunting nearby where the Beast and Parrish are fighting. The sound of electricity crackling worries Liam even more, who turns back to Scott. "Scott? You hear that?" Liam asks him leaving Jules and Brett confused. "I heard that." Lydia says with a weak voice. "Lydia, save your voice."
Liam looks down at his feet, and when he realizes that they're walking through standing water, his eyes widen in shock as he quickly lifts Lydia off the ground. Hey...Lydia, get out of the water!" He says as Lydia frantically grabs the pipes running along the walls and pulls herself up so her feet are no longer in the puddle, but the rest aren't able to get away fast enough before they're all electrocuted which leads to them collapsing onto the floor.
Theo appears behind them, revealing that he is the one who electrocuted them, before he grabs Lydia by the shoulders. "Sorry, Lydia." Theo says as Lydia whimpers. He throws her over an open grate. She starts to fall but is saved by Scott grabs her by the wrist. But when he tries to pull her up, Theo kneels behind him and stabs his claws into Scott's back, causing him to groan in pain.
"Feel that, Scott? Kanima venom." Theo says which makes Jules eyes widen as she realizes that Theo had killed Tracy and obtained her powers. "Just let it happen. Let it go. Let everything go." Theo says as Scott screams in horror as he struggle to hold Lydia up, feeling the kanaka venom paralyze him. "NO!" Scott yells as Lydia falls down.
The group continues to recover on the ground and Theo smirks devilishly when he hears the sound of the Beast approaching. "You hear that? That's the sound of real power." Theo says as he wolfs out and tunes to walk around the corner to see Sebastien who seemed to be amused by him. "Another arrogant youth. A contender to steal my name? You think you can take it from me?" Sebastien says in his deep french accent. "I just want your power." Theo says as he lunges and Sebastien grabs one of his wrists and Theo uses his free hand to stab his claws into Sebastiens stomach. However, Sebastien just looks at him, both smug and amused, and Theo starts to panic when the venom does nothing to him. Sebastien closes his eyes, and when he opens them, they glow bright blue as he starts to transform into the Beast. Dark veins appear on Theo's face as he tries to take Sebastien's pain, life, and power, but the Beast simply throws him against the wall before turning and walking away as he shifts back. He hears the ultrasonic emitters and starts to follow the noise while Theo pleads with him.
"No! No!" Theo starts as he tries to crawl away, but he turns back when he hears footsteps approaching. He sees Deucalion, followed closely by Jules, Brett, Scott and Liam. Theo's eyes widen in shock when he realizes he had been played the whole time. "You lied to me. You and Scott..." Theo says as Deucalion look at him with satisfaction. "That's right, Theo. The whole time." Deucalion says as he removes his glasses and closes his eyes. When he opens them again his eyes are back to normal revealing that he had been lying about his blindness the whole time.
"It would've never worked..." Theo says realizing he couldn't take the Beasts powers like he took Josh and Tracy's. "It could have worked... with Belasko's talons." Deucalion says as Jules realizes that what Scott had given Stiles to help Malia defeat the Desert Wolf. Before Theo can react further, Deucalion grabs him by the throat and snaps his neck.
"You broke my neck!" Theo says as Deucalion rolls his eyes as he stands to his feet. "And good luck with that." He says as he turns his attention back to the group, ignoring Theo. "There's an access grate that leads to the sub-level. I think we can get to Lydia there." Deucalion explains to them. "What about Mason?" Liam asks worriedly. "We can still save your friend." Deucalion says reassuringly. "Let's go." Scott says as the group tunes to leave, however before they can, Gerard and Chris them the corner. Gerard soon shoots Deucalion in the stomach and he clutches his wound as he slides down the wall.
"This just isn't my day..." Deucalion gasps out as Gerard smiles cruelly while Chris looks evidently unhappy whit Gerards actions. "This is a surprising alliance, Scott! You and Deucalion? How long have you been planning this clever little double-cross?" Gerard asks as Chris walks over so that he's standing between Gerard and Scott. "About as long as he and I have been planning this one." Chris says leaving Jules shocked and Brett confused. Chris roses the pike to Scott and then pints his gun at Gerard who does the same.
"What are you doing?"Gerard asks him. "I knew when I brought you back, it would never be about saving lives. Only about immortalizing your own." Chris says keeping his gun trained at his father, Chris turns to look at the group, who all look surprised.
"Scott, Jules, go." Chris says as Jules gives him a smile. "Go, now!" He says as they all turn and leave without another word, but as soon as they turn the corner, a gunshot is heard. Scott, who still had the cane in hand continued walking as the group follows him. After a moment Liam sighs and stops them all. "I'll do it." He says which makes the group give him a sympathetic look. "Liam..."
Liam tries his best to remain unemotional about their current situation. "It should be me. If you get me close enough, I'll do it." Liam says as he reaches for the cane in Scotts hand. "It won't have to come to that. We're saving him, no matter what it takes." Jules says to him as Brett nods in agreement.
"We're not killing your best friend." Scott says as Sebastien suddenly appears from the other side of the hallways.
"That belongs to me." He says as they all turn to face him. "It's a family heirloom. I'd like it back, please." He tells them. "It's all yours. Just give us Mason." Scott says as he shrugs. " Unfortunately, I would not know where to begin. And, while I've benefited from his memories, I don't have much use for an alter-ego." Sebastien says as he sighs leaving the group furious. Scott tunes to the group as they nod, the boys wolf out while Jules' aura begins to envelop her and the group is left stunned at her appearance but quickly turn their attention back to Sebastien.
"You want it? Come and get it!" Scott says as they all lunge for Sebastien as his eyes glow bright blue.
The sword-cane clatters as it falls onto the floor while the group fight Sebastien, in Beast-mode together. The Beast punches Liam in the face before engaging in a fist fight with Scott, which causes Scott to be tossed several feet backward. Brett tires to claw at him but is quickly thrown back as well. Jules is the only one left and she grabs Sebastiens arms preventing him from clawing arms her. He tries to overpower her but with her new found abilities her strength had enhanced. Eventually, Brett, Scott, and Liam quickly hop to a crouching position before roaring and lunging for the Beast at the same time. Jules pushes the Beast back but he slams his fist in the down on the ground, causing a concussive blast that throws them all against the pipe-lined walls. They groan in pain and writhe on the ground as they recover from this blow, just as the Beast, who has shifted back into a partially-transformed Sebastien, walks over to Scott and grabs him in a choke-hold.
"You're strong-- there's no doubt in that. But neither of you fight with a killer instinct. Let me show you how to go for the throat..."Sebastien says as his long and sharp claws extend as he grips Scott in a tighter choke hold. and Liam, seeing the sword-cane laying nearby, gets up and grabs it. Sebastien hears this and turns around, still strangling Scott, and turns to Liam as Scott desperately tries to stop him.
"Liam, wait! We can still save Mason!" Scott says to him. "Well, who's going to save you?" Liam says panicked. " What kind of werewolves are you?" Sebastien asks in confusion. Despite Scott's warning, Liam roars and lunges for Sebastien with the sword in hand as Brett helps Jules up from the floor.
"NO!" Scott yells as Sebastien shoves Liam backwards before he turns to Scott, gripping his neck tighter. Jules tries to run and save him but Liam and Brett hold her back. However, when Sebastien claws stab the back of Scott's neck, he starts to see a flood of memories in Scott's mind, all of which are about Allison
"Marie-Jeanne?" Sebastien asks which leaves the rest of the group stunned. Scott immediately smacks Sebastien's hands away from him and scampers backward to put some space between them, just as Lydia and Kira finally arrive to finish their plan. "Mason..." Lydia says frantically. Sebastien turns toward her and scoffs as he stalks toward them, and Kira looks alarmed as she turns to Lydia. "I think you're gonna need to try it a little louder..."Kira tells her.
Sebastien's eyes glow blue as he approaches them, and Lydia takes a deep breath before she bellows at Sebastien as loud as she can while he transforms into the Beast. "MASONNNNN!" The force of Lydia's voice is so strong that it hits the Beast in waves, and the group looks shocked as they see Lydia's new powers in action for the first time. The Beast raises his hands to cover his face from the force of Lydia's scream when suddenly, he bursts into a cloud of shadows from which Mason stumbles out.
Corey, who had been invisibly observing the situation the whole time makes himself visible and rushes forward to catch Mason before he falls. Mason looks around in confusion as the shadow-cloud that is Sebastien's life essence floats around without a corporeal body. Jules, Brett, Kira, Lydia, Scott, and Mason all smile in relief that their plan actually worked until the Beast's spirit screeches and heads toward them. Before they can react, Parrish appears and wraps his arms around it, somehow able to touch him without him having a physical body. Parrish then looks over at Scott as he struggles to hold on
"Scott!" He yells out as Scott rushes over and picks up the unsheathed sword, and tosses it toward the Beast which goes through its chest and causes it to disappear in a burst of black shadow and blue light. They all breath a disbelieving sigh of relief and look around at each other. "Is everyone okay?" Scott ask as suddenly Theo's voice is heard.
"Not everyone!" They turn to see him standing at the end of the adjacent hallway, electricity crackling around him as he glares at them furiously. Kira stares at him in horror for a moment until something clicks in her mind, and she rushes to the front of the group just as Theo shoots a bolt of electricity at them, which hits the blade of Kira's katana and passes harmlessly through her body. Kira smiles smugly at him as her Kitsune eyes come out.
"The Skinwalkers have a message for you, Theo."Kira says which leaves Theo horrified. "Your sister wants to see you." Kira finishes as she takes her Katana that was glowing a bright blue and dogs it into the stone floor causing a crack in the ground that opens up into a whole next to Theo. Just then, Theo's sister crawls out and glares at him as she grabs him by the legs and pulls him underground with her. Theo struggles to stay up and begins hysterically pleading with the others, who are just gaping in shock. "Scott, help me! No! No!"
For a moment, Jules begins to feel bad for the boy as his pleads continue. "Scott! Help me! Scott! No, Scott! Help me!" Theo pleads as he's finally pulled down into the sink hole. The hole then closes itself up and the McCall pack and it's allies look around at each other. Jules feels like she could finally take a breath of fresh air as Brett kisses her for head. "Is it finally over?" She asks him as he smiles.
"Yeah, it's over."
