"Previously on Teen Wolf..." "There's four steps." "We get into Eichen, we get into the Closed Unit, get Lydia, get out." "If we don't do this, she's going to die in there tonight." "We're in." "We did it." "Stiles..." "You're going to die if you stay." "Hello, this is Natalie Martin." "I need to see my daughter immediately." "We're here for Lydia Martin." "Lydia, I'm not leaving you here." "I'm looking for a Hellhound." "You wanted a Hellhound..." "I think you found one." "Come on." "We're getting Lydia out of here." "Back off." "I said back off." "Take him." " The guy's on fire." " You'll heal." "Do it." "Theo, this isn't working." "Sorry Theo, but I'm not done with her yet." "Hey!" "Lydia!" "Lydia!" "Lydia!" " Don't go." " I have to." "Stay." "Stay here?" "With you?" "Stay with us." "Theo thinks he's gonna be able to take its power." "He's crazy." "It's gonna rip his head off." "But you think Scott can save everyone?" "I know he can." "It's different now." "I think dying did something to him." "It did something to me, too." "But none of it was good." "What if it happened again?" "What if you got hurt?" "What would you want me to do?" "Now that you know everything." "Starting to question where your loyalties lie?" "Or maybe you're starting to understand your role." "What role?" "Why would Theo leave you here?" "Why not leave Josh or Corey?" "You're stronger and faster than both." "And more fearless." "I know why I'm stuck here with you." "Because when it comes to Liam," "I'm a liability." "You could leave." "You could go off to help them." "No one has to know." "Except for you." "Oh, I'm no friend to Theo." "You want to help Liam?" "Worry less about being a liability and more about your ability to lie." "Does anyone have eyes on the Closed Unit?" "I need a status report." "It's a war zone down here." "Uh... 10-4." "And what about the patients?" "Lydia Martin?" "Who is this?" "It's..." "Unit Nine." "There is no Unit Nine." "Who is this?" "How did you get..." "All right." "We need to figure out another way to get into this Closed Unit." " How do we get through the mountain ash?" " I don't know yet." "But there's somebody else here that might be able to help us." " Who?" " Meredith." "Let me try." "You're not gonna find her without me." "I don't know how long I'm going to last." "How did you stop it before?" "Scott carried me outside, which almost killed him." "Okay, uh..." "Maybe we could try grounding you to something." "You have a degree in electrical engineering?" "'Cause I don't know how to do that." " You have to get out of here." " I can't leave you." "I should've stayed in the desert with the Skinwalkers." "I can't control this." "I'm never going to be able to." "Kira, it worked." "You saw it work." "You controlled it enough to cause the brownout." "You can stop it." "I can't!" "Malia, go!" "Meredith?" "Meredith?" "It's Scott." "Scott McCall." "Stiles." "I want her out of here, too." "I've got her scent." "What do you want?" "What's the difference?" " Huh." " I can find her." "You can't." "It leads to the tunnels, doesn't it?" "There's miles of them." "They could be anywhere by now." "Hey." "Meredith, can you hear me?" "We need your help." "We're trying to find Lydia." "We're trying to get her out of here." "Scott, I think we better go." "Meredith, listen." "There has to be another way to get to Lydia." "We can't get past the mountain ash." "How do we find her?" "Scott..." "I could hurt you." "Okay." "Kira?" "Kira." "I wouldn't do that." "Electricity's still coming off her." "I can feel it from here." " I can help her." " Why?" "Because I need your help." "With him." "Meredith?" "Oh, sh..." "She doesn't have much time." "What's happening to her?" "She's being consumed by her power." "Dr. Valack thinks it's worth it if she can answer the question." "What question?" "Who is the Beast?" "She can answer that?" "Not yet." "Not until the screams in her head are loud enough to kill her." "How do I get to her?" "You can't." "You won't be able to get past the mountain ash." "But someone else might be able to." "Who?" "The Hellhound." "You mean Parrish?" "They're connected." "Find the Hellhound, and he'll find the Banshee." "Five texts in two minutes?" "Someone's trying to get your attention." "Maybe you should go." "I'm obviously not going anywhere." "Could you please shut the hell up?" "I have a feeling you and I are going to be friends, Hayden." "I think we're going to discover a lot of common ground beneath our feet." "Now is that really necessary?" "It's Kanima Venom from Tracy." "Enough to paralyze you for a couple hours." "If we're going to be friends, Hayden, you really need to learn to trust me." "Now I trust you." "Save her." "Oh!" "Is he out?" " Yeah." " Okay." "I thought you had her scent." "I lost it." "So find it again." "What do you smell down here, Stiles?" "Chemicals and fecal matter." "Although, I'm pretty sure the fecal matter is you." "I smell it, too." "It's all that I can smell." "Which is why I'm trying something else." "So can you shut up and let me concentrate?" "I'm gonna find her." "You know you won't, Stiles." "You're going to have to trust me." "Trust you?" "The guy who murdered his own sister when he was nine?" "Yeah, I was nine years old." "I also believed a guy in a red suit came down the chimney to deliver presents." "So when three people in leather masks showed up and said that my sister wanted me to have her heart," "I believed them, too." "So then together you gutted and killed her." "That's a beautiful story." "I watched her fall into the water and freeze to death in minutes." "Do you think I had any idea what was going on?" "I think you pushed her." "And I think you liked it." "What direction was that?" "Where is it coming from?" "Everywhere." "Just hold on a little longer, Lydia." "You can make it." "I want you to focus on this, Lydia." "And what other sounds you hear now, push them aside." "Focus on this sound." "That's it." "Focus on this sound and my voice." "All right, Lydia?" "Don't worry, Lydia." "Nurse Cross wasn't nearly as strong as you are." "Parrish?" "Parrish." "Parrish." "Parrish, hey." "Can you hear me?" "How did I get here?" "We don't know." "We just followed the burning smell." "Parrish, listen." "Eichen's in lockdown." "There's no way for us to get out unless Plan B works." "Plan B?" "What's Plan B?" "Don't worry about it." "Right now, we need you to find Lydia." "Me?" "LIAM:" "Actually, not completely you." "We kind of need the other you." "The Hellhound." "Why isn't he healing?" "Maybe he can't." "Maybe it's too much." "Or maybe it's the pain." "He's going to die, isn't he?" "His heartbeat's getting slower." "What do we do?" "You can't heal him, can you?" "No, but I can take his pain." "It could help." "It might even get him to start healing." " Then do it." " You first." "You said you could help her." "Yeah, but it's not like taking voltage from a car battery." "She's got a lot more power than that." "Are you going to do something or not?" "When you help her." "I don't trust you." "I don't trust you either." "All right." "We go at the same time." "You ready?" "All right, here we go." "Nothing." "Great." "You're just as useless as I am." "I'm trying to help save her life." "Would you just drop the altruistic crap?" "You want Lydia because she gets you to Parrish, you want Parrish 'cause he gets you to the Beast." "So what?" "I want it dead, too." "After you take its power, right?" "We know why you got the talons and we know you're looking for Deucalion." "I found Deucalion." "You're right." "I'm going to help Parrish stop the Beast." "I'm going to take its power." "And then I'm going to break its neck." "So maybe I'm not the good guy in your eyes, but I might end up being the guy that saves all your asses." "Break it." "What?" "The sound travels through the pipe." "You'll hear better, dumb-ass." "Break it." "Lydia?" "Can you hear me?" "What do you want from me?" "I want your help against the Dread Doctors." "They ruined me." "Destroyed me." "They drove me to obsession, consigned me to professional ridicule." "People thought I was a monster when I was simply trying to open their eyes." "Now you want me to be your eyes." "You'll see things, Lydia." "Things no one else can see." "You may not survive," "but you might save the lives of your friends." "Do it!" "We have to slow your mind first." "There's too much activity in your brain." "We have to get from a gamma wave to a theta." "It's too loud." "I can't." "If I try the mask now it will kill you." "You have to calm your mind." "You understand what they've created." "The Beast." "The Beast of Gevaudan." "An engineered version of it." "But it's not yet fully grown." "It's still bound to its host, the teenage Chimera inside." "And it still requires the Dread Doctors' protection." " Damnatio Memoriae." " That's right." "The Beast was a man first." "A human killer in the late 1700s." "The Dread Doctors are trying to get it to remember itself." "To remember the man." "When that happens, the teenager is gone." "Anybody know how we're supposed to get out of here?" "This place is still in lockdown." " It's not just locked." " Yeah, I can feel it, too." "What are we supposed to do?" "Just wait here?" "There's a Plan B." "We've got a guy on the outside in case this happens." " Who?" " Mason." "Mason's going to unlock the lockdown?" "How's he going to do that?" "He's got the blueprints of the building." "And he has the full map of Eichen's electrical system." "All he has to do is get into the transformer shed behind the building." "Don't worry." "Mason knows exactly what he's doing." "Liam, call me back, I have no idea what to do." "And I'm panicking." "I'm completely and totally panicking." "I drove around this building, like, four times and I can't find this transformer shed." "Well, actually, that's partially right." "Because I found where the transformer shed is supposed to be." "But it's not a shed anymore." "It's a wall." "Like, a very big wall." "So, I mean, I tried calling Hayden." "And she still isn't here, and I heard alarms go off." "Now I don't know what to do." "So, Liam, just call me." "This teenager, Lydia, is the last Genetic Chimera." "A young man or a young woman, maybe even someone you know." "A success where Theo and the others were failures." "But we went through the list of Genetic Chimeras." "There's no one else." "There must be one you missed." "Another way they could have two sets of DNA." "If you could see the face of this teenager, discover its identity, then your friends would have a fighting chance." "The mask can help you see." "Lydia!" "Lydia!" " What the hell are you doing?" "Get the door." " I'm trying." "I'm sorry." "But time's up." "You came back." "We're getting you out of here, okay?" "You can't." "It's too dangerous." "Lydia, please shut up and let me save your life." "Okay, here we go." "Gonna ram the wall." "Gonna ram it with my car." "Just smash through it." "Take out the power." "And save my friends." "Here we go." "All right." "Just ram it and destroy my beautiful car that my parents bought me on my birthday, but I'ma save my friends." "Here we go." "Ram the wall." "All right." "What the hell are you doing?" "Oh, thank God." " Can we use your car?" " Are you kidding?" "A car is not getting through that." "What?" "You have any better ideas?" "Uh..." "Hayden?" "Hayden." "Hayden." "Wait." "Whoa." "Wait, Hayden." "Whoa, whoa, wait!" "I'm in!" "Okay." "Um..." "Okay." "There's two red levers." "You're going to pull them both." "You see them?" "I see 10." " Two." " No. 10." "There's ten red levers." "What do I do?" "Mason?" "Mason, what am I supposed to do?" "Parrish?" "How's he going to get through the mountain ash?" "He's burning it right out of the walls." "Okay." "You gotta try and stay on your feet." "The plan didn't work out too well." "So I'm gonna need your help, okay?" "You had a plan?" "Yeah." "It was good on paper." "Not too much in reality." "I can't hold it." "Lydia..." "Stiles, run!" "Where to?" "This way." "Come on." "Hayden, just pull them all." "Just pull them all!" " There's a gate up ahead." " What about Mason?" "He's on it." "Trust me." "What's..." "What's happening?" "Plan B." "Liam, slow down." "Liam, wait!" "I told you." "He did it." "We gotta get to Stiles' Jeep." "Can you stand?" "Is she okay?" "No, we need to go." "Give me the keys." "We gotta get her to the clinic." "Sorry, but she's coming with me." "Okay." "Tracy, just wait." "You don't know what's about to happen." "I'm taking her." "That's what's happening." "And none of are you going to do a thing..." "Could somebody please get my daughter out of this hellhole?" " Scott." " Yeah." "I'm trying, I'm trying." "We're almost there." "Lydia, just hold on, okay?" "Hey." "Lydia, Lydia, hey, hey, hey, hey, hey." "Look." "You're gonna get through this, okay?" "Lydia, look at me, you're gonna make it." "But you're not." "Get her on the table." " Whoa, whoa, whoa." " Hold her." " Doc, think you gotta do something." " I will." "But right now, I need you to keep her still." "Steady." " Steady." " What the hell is that?" "Mistletoe." "Mistletoe?" "She's got a fricking hole in her head." "Stiles, help." "Steady." "Lydia." "Lydia?" "Lydia." "Lydia, come on." "No, no, no, no, no." "Come on, Lydia." "Wake up." "Come on." "Wake up." "Can you hear me?" "Lydia." "Lydia, open your eyes." "Come on, come on." "Come on." "Listen to me, Lydia." "Hey, show me your eyes, okay?" "Lydia, you have to open your eyes." "You okay?" "You're okay." "Want to try to sit up?" "Mom?" "Oh, honey." "They saved my life, Mom." "Stiles saved me." "I'm not paying for the windows." "I said it was for emergencies only." "I had an emergency." "Don't worry, Theo." "A little dissension in the ranks is perfectly healthy." "Did you find what you were looking for?" "No." "But I think I might have found something better." "A way to answer the question." "Who is the Beast?"
