"Not anymore." "You mean the whole building?" "Gone." "I'll go tell stilinski." "And see if you can find allison." "She's not answering her phone." "Notice how strong the scent is up here?" "Ever hear of chemo signals?" "Chemical signals that communicate emotion." "And just our sweat can give off anger, fear or disgust." "Take a deep breath" "And tell me what you feel." "Stress." "And anxiety." "What was he doing up here?" "I don't know." "But there was definitely some kind of struggle." "With who?" "Himself." "Where is everyone?" "We get a lead on our sword-wielding maniac?" "Nope." "But we've got posters up all over town for your guy." "Not exactly how I described him to the sketch artist." "Well, you're not exactly the highest priority of the tonight, agent mccall." "What does that mean?" "What's the high priority?" "Didn't you draw this?" "Put that back." "It's yours right?" "It's one of them." "I guess." "He likes you a lot, doesn't he?"

"(voices whispering loudly)" "You didn't hear that?" "Lydia, I'm not sure anybody hears what you hear." "They're whispering." "Something about a house." "What house?" "(voices whispering loudly)" "That one." "What's eichen house?" "A mental health center." "It's where william barrow, the shrapnel bomber, was committed." "Is that it?" "That's where he is."

"Did you notice" "That we've stopped shivering?" "Do you know why that's a bad sign?" "It's the body trying to conserve energy." "It was my fifth grade science report." "Hypothermia." "Our speech is starting to thicken." "Then comes fatigue." "Confusion." "We're going to die if we don't get out of here." "Stop saying that." "Stop saying we." "We're just trying to keep you from freezing to death." "You better get up, stiles." "How?" "There's a freaking steel-jawed trap on my leg!" "Is there?" "(sobbing)" "Notice something different?" "It was on your right leg before, wasn't it?" "No..." "Are you sure?" "What is this?" "What are you doing?" "We're trying to save you, stiles." "We're trying to save your life." "Stilinski:" "Lydia," "I don't want to say "are you sure about this" but..." "No, he's here." "I swear to god he's here." "I need access to all basement rooms in this facility."

"(engine revving) melissa:" "So what are you saying?" "I'm saying the real question might be," "How do we know he's not still asleep?" "You mean he's been asleep the whole time?" "Well, people who sleepwalk can do crazy things." "One guy goes down to the kitchen and cooks an entire meal." "Another guy is found mowing his lawn naked." "Why's any of that matter?" "Remember that townhouse apartment we lived in?" "There was that one night I came home drunk..." "Oh, one night?" "Let me finish." "So I'm drunk, passed out on the bed." "I get up to go to the bathroom." "Then all of a sudden I hear you yelling "what the hell are you doing?"" "Because you were in the closet peeing into the laundry basket." "Yeah, I thought it was the bathroom." "Oh, no, you were drunk off your ass." "Yeah, but I was convinced it was the bathroom." "Yeah." "So how do we know isn't just convinced he's in some kind of basement?" "And isn't actually there." "I think when he called scott, he was still asleep." "And is still asleep right now." "Then where is he?" "I got an idea about that too." "You don't understand, do you?" "It's a riddle." "Do you know any riddles, stiles?" "A few." "What gets bigger the more you take away?" "A hole." "What gets wetter the more it dries?" "A towel. (sniffling)" "When is a door not a door?" "When it's ajar." "Everyone has it," "But no one can lose it." "What is it?" "I don't... (exhales deeply)" "(shivering)" "Everyone has it," "But no one can lose it." "What is it, stiles?" "I don't..." "I don't know." "Everyone has it," "But no one can lose it."

"(yelling) stiles." "(screaming) wait!" "No, wait!" "Stiles!" "Wait!" "Stiles, you're all right!" "Okay!" "You're all right." "Stiles, you're all right." "(breathing heavily)" "(banging on door)" "What the hell have you been doing?" "Sleeping." "What the hell are you doing?" "You didn't get any calls or texts?" "My phone's off." "I never turn my phone off." "(phone pings and chimes)" "Sleepwalking?" "Is he okay?" "Yeah, they found him a few minutes ago." "They're bringing him to the hospital." "I don't know what happened." "I never turn it off." "(static blaring)" "Who's that?" "(man speaking japanese)" "(engine starting)" "So, you think he was just sleepwalking?" "Or is there something more to it?" "In this town there's always something more." "What if I told you I know something more?" "I kind of overheard..." "Well, I listened in on stiles talking to scott." "How he thinks he was the one" "Who wrote that message in the chemistry room." "The message telling barrow to kill kira." "You think stiles, skinny, defenseless, stiles" "Is the nogitsune?" "A powerful, dark spirit?" "I'm not the only one thinking it." "I'm just the only one saying it." "This thing wants to possess someone and chooses stiles?" "Why wouldn't it take someone bigger, stronger?" "Someone with a little more..." "Power." "(sighs) he's sleeping now." "And he's just fine." "He doesn't remember much." "It's a bit like a dream to him." "Thank you." "It was that repellent we sprayed in the coyote den to keep other animals out." "I couldn't go near it without my eyes watering." "It's just a good thing he mentioned it over the phone." "No, it was more than that." "Thank you." "It was a lucky connection." "Mccall, can you shut up please and accept my sincerest gratitude." "Accepted." "All right, you two." "You've got school in less than six hours." "Go home." "Go to sleep." "Okay." "(indistinct chattering)" "I don't know what happened." "I was so sure." "Yeah, I wasn't much help either." "Doesn't matter, if he's okay." "(metal clanking fast)" "Lydia, do you hear something?" "No." "(clanking stops)" "I didn't hear anything." "(locker closes)" "(phone chimes)" "(soft music playing)" "Scott." "Hey..." "Derek:" "He's a little preoccupied." "But I can help you." "Why would you want to help me?" "Because I want you to tell me everything that happened at" "The power station with william barrow." "Actually, I want you to show me." "It was the other day." "I asked him some questions." "Just symptoms and, um..." "Man: (over pa) blueteamto icuplease." "Blueteam,icu." "Yeah." "It's okay." "I think I, uh..." "I think I know what you're talking about." "I've been writing these down for the past two weeks." "I think we need to do some tests." "It was around here, I think." "But everything kind of looks the same now." "Kira:" "What is that?" "Is that a baseball bat?" "It's stiles's bat." "It's magnetized." "Kira," "I'm going to need you to tell me everything you know about foxfire." "(man speaking japanese)" "(beeping)" "You're right." "It's japanese." "Who left this on your phone?" "I don't know." "All of the messages are the same and they all say blocked id." "Can you translate it?" "Mostly." "The man speaking is giving instructions actually." "The first line is," ""all evacuees are required to stay" ""at least 10 feet back from outside fences."" "What does that mean?" "What fences?" "The fences surrounding a japanese internment camp during world war ii." "After pearl harbor," "Japanese-americans were rounded up and put in camps." "This man is reading instructions to prisoners upon their arrival." "(speaking stops)" "Well, where does something like this come from?" "I have no idea." "Because it's fake." "It mentions the name of the internment camp as "oak creek."" "There was no internment camp named oak creek in california." "You okay?" "Yeah." "I'm just a little hyper-sensitive to loud sounds today." "(locker closing)" "They're doing tests on stiles all afternoon." "I was going to go over at around 6:00 to visit." "You want to come with me?" "I should probably just go home." "(locker closes)" "You sure you're okay?" "Yeah." "I'll text you later." "(thuds)" "I'm not sure I know how to pronounce this." "Or if it's not actually a misspelling." "Just call him stiles." "Okay." "Stiles, just to warn you," "You're going to hear a lot of noise during the mri." "It's due to pulses of electricity" "Going through metal coils inside the machine." "Uh, if you want we can get you earplugs or headphones." "Oh, no, no, I don't need anything." "Hey, we're just on the other side of that window." "Okay?" "Okay." "You know what they're looking for, right?" "It's called frontotemporal dementia." "Areas of your brain start to shrink." "It's the only form of dementia that can hit teenagers." "And there's no cure." "Stiles, if you have it, we'll do something." "I'll do something." "I don't know if I should go in." "You're going to tell scott" "That barrow might have used foxfire created by me" "To jump start the nogitsune's power inside stiles." "Yeah." "Basically that I helped a dark spirit" "Take control of his best friend." "You should probably wait here." "Doctor:" "Okay, stiles." "Thiswilltakeabout 45minutesto an hour."

"(metal clanking)" "(metal clanking continuously)" "(upbeat music playing)" "(metal clanking continues)" "You know the stuff you we're telling me about chemo signals earlier?" "It reminded me of the time you we're teaching me" "To use anger to control the shift." "I think you ended up teaching me more about that." "Are you teaching me again?" "Think of it more like sharing a few trade secrets." "You know, I took cora back to south america, right?" "It's where she spent most of her time after the fire." "But that's not the only reason I left." "I needed to talk to my mother." "Your dead mother?" "She told me something that changed my perspective" "On a lot of things." "She said that my family didn't just live in beacon hills." "They protected it." "This town needs someone to protect it." "Someone like you." "And someone like you to teach me a few trade secrets." "What?" "He was trying to protect us." "Stiles was protecting us." "From himself." "What are we looking for?" "I'm not sure." "But I think stiles wasn't just up here struggling with himself." "I think he was struggling not to do something." "(metal clanking)" "(inaudible)" "Doctor:" "See this?" "The tissue here and there." "Both those spots are showing signs of atrophy." "Atrophy." "Doctor:" "I'm sorry." "(melancholy music playing)" "(panting)" "(metallic clanking)" "Nogitsune:" "Have you figured out my riddle yet?" "If you answer correctly," "We might consider letting them go." "Letting who go?" "Your friends." "Your family." "Everyone who ever meant something to you." "We're going to destroy all of them, stiles." "One-by-one." "Why?" "Everyone has it," "But no one can lose it." "What is it?" "I don't know." "Everyone has it," "But no one can lose it." "What is it?" "I don't know." "Everyone has it," "But no one can lose it." "What is it?" "What is it?" "I don't know." "(whispering) what is it, stiles?" "A shadow." "(electricity crackling)" "What was that?" "It sounded like a power surge." "Where's my son?" "(people clamoring)" "You know me." "Then you remember that I won't be deterred" "By your choice of host." "Even if it's an innocent boy." "Are you threatening us?" "Now I'm threatening you." "We're not really afraid of your little fireflies." "Noshiko:" "If the oni can't defeat you," "I know someone who will." "(electricity crackling)" "Oh, my god."
