"Previously on Teen Wolf..." "The Beast..." "The Beast of Gevaudan." "The Beast was a man first." "A human killer in the late 1700s." "Marie-Jeanne faced the Beast armed with nothing more than a steel-tipped pike." "All of history will remember my name." "No one will remember." "They erased every detail of him." "Damnatio Memoriae." "The Dread Doctors are trying to get it to remember itself." "It's still bound to its host, the teenage Chimera inside." "Discover its identity, then your friends would have a fighting chance." "But I got its scent." "It's you." "Wait!" "What are we doing here?" "It was the only place I could think of." "Wait..." "What do you mean?" "Scott can't find you down here." "He can't follow your scent." "Okay, hold on." "It's not me." "I'm not even a Genetic Chimera." "You sure about that?" "It was on the bus." "After I made us disappear, I felt something." "I don't know how to describe it, but it felt wrong." "Completely and totally wrong." "And, trust me, every other second I'm with you is completely and totally right." "It can't be me." "After we left the bus, I lost you at the game." "Remember?" "Where did you go?" "I went to..." "I was..." "All those times you said the Beast showed up?" "Everything you said about frequencies." "Where were you all those times?" "The night at the transmission towers..." "The observatory downtown..." "The army base..." "All the times you said there were transmissions..." "Wait." "They can still find me." "They can find me by frequency." " Who?" "Scott?" " No..." "Them." "Run!" "Mason." "Come on!" "Mason..." "Come on." "Come on!" "Mason..." "Mason!" "Come on!" "You want me to put it on?" "Yeah." "You won't die if you put it on." "How do you know that?" "Or is it just that you don't want to put it on yourself?" "Or you?" "I'm not afraid to do it, Josh." "I'm just not stupid." "Are you not getting that it could kill us?" "You're the one with the power." "They want you to wear it, Josh, because the properties of the mask are based in electro-magnetism." "Pick it up and you'll see." "What is this thing?" "Product of genius and madness." "Two traits too often found in the same mind." "The man who created the first was known only as "The Surgeon."" "Using practices in the farthest edges of pseudo-science, he harnessed electromagnetic fields in the masks... infusing them with a unique and deadly power." "I'm not putting this thing on." "You want to know who it is?" "Do it yourself." "Lydia!" "I just came from his place." "Half of his stuff was gone." "You can't let him leave." "It's okay." "I got a call from Dispatch." "He's headed for the highway." "Can you stop him?" "Stopping him is one thing." "Getting him to turn around..." "Leave that to me." "I don't remember giving you any vacation time." " Those were new tires." " Well..." "Well, they're scrap rubber, now." "How about I call a tow for you?" "I'll call one myself." "You're both out of your minds." "You know that?" " You can't leave." " I can't stay." "I'm a Hellhound." "I have the word, "Hell" in my name." "Hell." "You're also one of my best deputies." "You guys don't get it." "The bodies I see in my dream are because of me." "And there's gonna be more." "A lot more." "I've been predicting death longer than you." "The things I've seen and felt..." "They don't always happen." "What if those people die because you didn't stay?" "Because you weren't there to protect them." "You said you were drawn to Beacon Hills." "I think you're here for a reason." "Hey." "We gotta find them." "It's Mason." "I know." "Everybody's looking." " What?" " Nothing." "It's just a scholarship." "I missed the due date." "We'll figure it out." "Right now, you're not going anywhere until you heal." "Okay?" "What?" "What?" "What did I do?" "Tell him." "You know how my mother wants to kill me?" "I think she might want to kill you too." "Okay, uh, that's disconcerting." "I should probably have a gun." "I'm not giving you a gun." "You have a gun." "The Desert Wolf who is trying to kill me, has a gun." "I think I should probably have a gun." "I probably shouldn't have a gun." "Mason?" "Mason!" " Hey." " Hi." "I lost it." "I lost the scent." "I'll help you find it." "My dad's got an APB out..." "For a 5'8" 16-year-old?" "I recommended nine-foot tall rampaging werewolf." "It still might not be him." "But, Hayden's at the school looking." "I can keep checking the woods." "My mom can check all the hospitals in the county." "We can find him." "What happens then?" "We figure out a way to save him." "Okay." "Where else could we look?" "Let's ask Corey." "Wait." "Wait." "It's not my fault." "They took him and I couldn't do anything." " They took him..." " Who?" "The Dread Doctors." "Wait!" "Don't..." "Wait, please." "Please, don't!" "No, no, no!" "No, no, no!" "What about this?" "They're useless if we don't know who it is." "Actually, they're just useless." "Didn't Hayden mention that?" "Where is she, by the way?" "I hope her moment of dissent didn't turn into actual desertion." "What about the other one?" "Corey?" "None of us can see him, blind or otherwise." "So, I'm guessing, he's not here either." "I'm leaving." "Oh, there goes another." "Your circle of trust is narrowing for you." "Your voice is getting on my nerves." "Paralyze his tongue." "You got it." "Tell me something, Tracy." "Just how powerless were you before this all happened?" "In my experience, it's the truly powerless who are all too eager to demonstrate their new-found strength." "So allow me to demonstrate something more helpful to our cause." "Trust..." "I told you I wanted Scott McCall's eyes." "That's why I let you take me." "Though I have been a willing guest this entire time." "As your father, I'm obliged to warn you this is dangerous." "As my father, I was hoping you wouldn't tell my mother." "That's dangerous, too." "I get it, Dad." "I need to learn balance." "Can't learn balance with the sword, the sword brings out the Fox." "You know it's more complicated than that." "Learning balance is critical to controlling the Fox." "What if the sword is critical to saving my friends?" "It's just a weapon, Kira." "You're the critical part." "I've got 800 years to find balance." "We need to help Mason right now." "I need my sword." "It was forged with a unique power." "It takes a certain power to put it back together." " You're going to need help." " From who?" " Whom." " Who?" "Just pick up the pieces." "Okay." "What now?" "I teach you what you've been so desperate to learn." "Feel that, Theo?" "That's the secret to taking power." "Pain." "Take their pain, take their life, take their power." "It's all or nothing." "You take until there's nothing more to give." "That's where you find the spark of power." "And then, you take that as well." "Pain." "Life." "Power." "In that order and only that order." "Do you understand?" "Perfectly." "I can feel it." "Good." "'Cause you just cost yourself one member of a small and inexperienced pack." "What do you think?" "I think he was small and inexperienced." "And if you've got his power now, you can put on the mask." "You can still save them." "You can save them all." "This kind of power requires risk, Theo." "Do it." "Put on the mask." "Discover the Beast's identity and guarantee your place as an Alpha." "As a real werewolf." "No!" "No!" "How stupid are we to be doing this?" "We're not stupid." "We're desperate." "How desperate?" "Incredibly desperate." "I told you we'd end up on the same side." "How about I punch you in the balls to remind you we're not?" "I love this kid." "I don't." "We know you're not on our side, Theo." "You said you wanted to help Lydia, but you left Eichen with something else, didn't you?" "You mean the mask?" "Are you worried about that?" "Did you put it on?" "Who did you see?" "Not Mason." "What's that mean?" "It's not him?" "It probably means he's a lost cause." "We all want the same thing." "We want Mason back." "Okay, but the difference is that we want him back alive." "Well, I'm open to compromise." "You still got the map with telluric currents on it?" "Bring it to the operating theater in two hours." "How desperate are we?" "Incredibly." "We don't need them to find Mason." "But you'll need them if you want Mason to trust you." "I can't take the power from him, can I?" "No, only the Beast." "But since the full moon is getting dangerously close, the opportunity might present itself sooner than you think." "Good." "As soon as you see that opportunity, take it." "If Scott figures out a way to save Mason, you won't get another." "But we've seen that thing up close." "How are we supposed to stop him when he's the Beast?" "You're not going to stop him." "You're going to paralyze him." "Me?" "Are you serious?" "It didn't work on Parrish." "It didn't work on a Hellhound." "The Beast is still a werewolf." "Just keep the tanks full, Tracy." "We'll need all you've got." "Still nothing from Scott and Liam." "Are we really sure this is a good idea?" "Uh, no." "No one thinks this is a good idea." "But you're trusting Theo, anyway?" "We're not trusting him." "We're using him." "What if he's using us?" "That's probably a given." "But, look, we're just trying to cover every place Mason could show up." "Malia and Braeden are at Scott's house." "Melissa's got the hospital." "Hayden and Corey are at the school." "Somebody's got to find him." "Let's hope they find Mason, and not the Beast." "They called him Der Soldat." "That's German for "The Soldier."" "I'm pretty sure he fought in World War II." "And he was a Nazi." "And an Alpha werewolf." "The Dread Doctors were using him to prolong their lives." "They've been doing it for decades." "Actually, probably longer." "How old are these guys?" "Who knows." "But wherever they go, he goes, too." "So how do we find him?" "Keeping him alive requires a pretty unique set of conditions." "There's got to be a power source." "It has to be underground..." "And on a telluric current." "Looks like we're going for a hike." "We got a hit and run." "Victim is a black male, approximately 16 years of age." "Blood pressure is 80 and dropping." "Nothing here." " Same here." " Anything on your end?" "Not a thing." "And I'm gonna lose my mind if I don't get out of this supernatural cage." "The Mountain Ash is there to keep you safe." "I should be keeping Stiles safe." "He'll be fine." "Call me if anything changes." "I'll pass." "Thanks." "Where is he?" "I thought we were looking for him." "You know who I'm talking about." " Deucalion?" " You shouldn't trust him." "And you're the one who let him live." "I'm not a murderer." "You still think you're gonna get through all this without killing anyone?" "I didn't say that." "We're close." "You get his scent?" "Which way?" "You think you're going to leave me behind?" "Liam..." " Look, he wants to kill him." " I just want his power." "You want to fight someone that actually wants to kill Mason?" "Go fight Parrish." "Who did you see when you put on the mask?" "I already told you." "It wasn't Mason." "Who was it?" "I saw a man dying in the snow." "He was impaled on a spear." "It's called a pike." "Lydia told us the story." "Then both of you know what it means." "Time's running out." "Where is he, Liam?" "What direction?" "This way." "Listen." "It's him." "Mason?" "It's connected to him." "Hey, it's me." "Oh, God." "I wish you just picked up." "I hate leaving messages." "I always ramble." "I always say stupid things." "And then when I finally get to the super important thing that I'm supposed to say, the voice-mail cuts me off and..." "Me again." "I have to leave." "But I'm coming back to help." "I promise." "Because you're right, Scott." "If anyone is going to save Mason, it's you." "It's us." "What is this thing?" "I don't know." "Liam, I can feel it." "It's in my skull." "Don't move." "Careful." " What are they doing to him?" " I don't know." "Guys, let's focus." "Mason, we're gonna get you out of here." "Hold him still." "Okay." "All right." "I'm going to try to pull it out." "Let me know if it hurts..." "It hurts!" "It definitely hurts." "I barely moved it." "Hmm?" "What?" "What happened?" "Who's dead?" "No one." "Well, at least not yet." "You okay?" "Yeah, I'm still thinking." "Still trying to figure out why Mason?" "I mean, he wasn't even on the Genetic Chimera list." "He is now." "Mason was born with twin embolization syndrome." "You mean fetal resorption?" "Mmm-hmm." "He had a vanishing twin in utero?" "Which accounts for two sets of DNA." "Can someone please say it with words that have less than three syllables?" "He ate his twin." "Oh, God." "But did it help?" "I don't know." "But it's just bizarre enough to sound like it might be important, right?" "It has to help." "There has to be something." "They wanted us here." "Liam, try to get that thing out of Mason's neck." "Theo..." "Theo Raeken." "He's coming with us." "Failure..." "Theo Raeken." "I'm not a failure." "Liam..." "Get out of here." "Just go." "Not a complete failure." "We learned from you." "Theo, he's trying to get to you." "This is what they want, don't give it to them." "We can't beat them." "The mark of a true failure." "Repeating the same mistake again and again." "We're taking Mason." "Then I'm taking what's mine." "Braeden, something's wrong." "We gotta go..." " Mason..." " Mason Hewitt." "He's a sophomore." "Liam's best friend." "And a mass murderer." "We're going to need to tell Scott the rest." "Not necessarily." "If there's a way to save him..." "The pike won't save him." "It'll kill him." "Mason Hewitt is gone." "But you still can't tell me where it is." "How do we know it's not a steel cup gathering dust in someone's antique collection?" "Oh, I think it's closer to us than that." "We'll find the pike." "Whatever shape it's in." "If we can't, then we're going to need a lot more firepower to take on the Beast." "How much firepower do you want?" "Let him go." "You have the entitlement and narcissism typical of your generation." "In that, you are a profound success." " God!" " Scott!" "Scott, I..." "I can't get it out." "I don't know what to do." "But your failure taught us one thing." "The banality of evil." "That you were and would always be an ordinary evil." "You think I'm ordinary?" "We believed that to resurrect the perfect killer we had to start with the perfect evil." "From you we learned true evil only comes by corrupting something truly good." "Not something." "Someone." "Liam, wait!" "Liam!" "Liam!" "Transformation..." "Transformation without frequency." "Mason!" "That is not my name." "Still here Braeden?" "Okay." "I love a cage match." "I know you can hear me." "I need your help." "Maybe I failed your test." "Maybe I don't have control yet." "But I'll do whatever I have to." "Whatever it takes." "Please." "Tell me how to save my friends." "Kira..." "We can help her." "But it comes with a price." "Everything has its price." "Success." "La Bete Du Gevaudan!" "I know your name." "Do you remember mine?" "Argent." "Who the hell was that?" "You've seen the Beast of Gevaudan." "That was the Man." "Sebastien Valet."
