Stiles and Sheriff Stilinski ride in silence. Both seem tempted to speak but don't. They pull up outside Eichen House (the mental health facility we all know by now) and without a word get out of the vehicle and stare up at the imposing metal gate and the edifice beyond. Scott arrives on his dirt bike, upset that no one told him that Stiles was moving into Eichen House for 72 hours. He's worried because Barrow and his fly-filled tumour came from this place.

The Sheriff explains that Stiles' MRI results looked exactly like those of his wife and he is terrified. He is going to LA "tomorrow" to talk to a specialist and Stiles has requested that he be locked away in the mental health facility so that he doesn't hurt anyone.

Scott tries to talk him out of the plan saying that "Deaton's got some ideas and Argent is calling people" to try to find something to help him rid himself of the Nogitsune. Stiles says if they don't find something then Scott must make sure he never gets out.

The Eichen House attendant explains the rules. There are no phone calls, emails or visitors allowed in the first 72 hours. As she lays out the process, a physical, meeting with a psychologist, and group therapy, Sheriff Stilinski becomes more and more agitated. The sounds of door buzzers and cell doors slamming fill his ears. The attendant takes Stiles shoes and gives him brown slippers because "no laces allowed" and then makes him empty his pockets of keys and other items.

Suddenly the Sheriff declares that they forgot Stiles' pillow and that they both must leave to go and get it. He manically explains that every time they've stayed in a hotel, the first thing they pack is Stiles' pillow. It is irrational, but he clings to this as an excuse to get his son away and home because "I'm not checking you in here if you're not going to get one decent night's sleep."

Stiles explains that he hasn't slept well in weeks and hugs his father tightly. Then Stiles is gone, off down the hall with the attendant, leaving his father standing alone and helpless.

As they ascend the stairs, Stiles sees someone he thinks he recognizes down one of the hallways. The attendant urges him on and when he looks back she is gone. On one of the landings above, a man is knotting a sheet and talking to himself, quoting a riddle. "I'm part of the bird that's not in the sky. I can swim in the ocean yet still remain dry." He then loops the knotted sheet around his neck in a noose and leaps from the landing hanging himself. In the crowd of onlookers gathered in the stairwell below, Stiles sees the Nogitsune.

(It's a riddle, "I'm part of the bird that's not in the sky. I can swim in the ocean yet still remain dry. What am I?" The answer is "Its shadow" since when the bird is flying the shadow is cast on the ground below it and when it flies over water the bird is reflected in the water below.)~~~

Chris Argent is talking with the payphone at the Sheriff's Station.

"Did you have any trouble with Ikeda?" Chris asks.

"Only minor, the wolf was exactly where you said it would be" Deaton replies. "But we have two problems now. First, the lichen is not a cure. It'll wear off in a matter of days"

"But while it does work, the Oni won't go after Stiles right?" Chris asks.

"I hope. Eichen House has an unusual history. It might not be all that safe there for the Oni there as well"

"What's the second problem?"

"I checked with your contacts in Japan. The yukuza boss you saw killed by the Oni never found the scroll"

"What scroll?" Scott asks while Allison and Selene start thinking about what he might mean.

"A Shugendō scroll. Shugendō were the ascetic mystics of Japan" Deaton explains.

"The scroll had information on how to exorcise a nogitsune" Chris adds.

"So we need to find that scroll" Scott realises.

"Exactly. And I did get a name of the man who last purchased it Kincaid" Deaton tells them.

"He's with Katashi. He's the guy that met with me and Isaac for the buy" Selene explains.

"Sounds like Katashi wanted the scroll for himself"

"But Stilinski already told me hey found nothing like it among his things. And a paranoid like Katashi would keep it close. Probably on him at all times" Chris explains.

"Do they come in different sizes?" Selene asks out of the blue.

"Yeah, any size" Deaton confirms.

"His finger. The scroll would be in his finger" Selene then explains.

"Well, it's a little too late for that. Derek overheard that a lawyer came by yesterday. All the stuff is been claimed by Katashi's daughter" Chris says.

"I can get it" Selene then states.

"How?" Scott asks

"I know her. I can get the Shugendō scroll. Give me a few days" Selene plans.

"That's all Stiles has" Deaton then agrees.

After witnessing the suicide, Stiles is desperate to use the phone. The attendant says "the accident that occurred is being taken care of." Stiles baulks at the use of the word "accident" and she changes it to the slightly more accurate "incident." He pushes her to use the phone and she threatens him with their "five-point restraint system."

Stiles' roommate, who is himself strapped down to his bed, says sleep is the better option.

The roommate introduces himself as Oliver. He says he heard the suicide because something in the way the building is constructed causes everything to echo "eventually." He says they call it "Echo House."

Stiles sits up the whole night. In the morning, Oliver has a coughing fit. He says he swallowed a bug "the other day" and it feels like he still has it stuck in his throat. Oliver gives him the tour and explains that violent patients are locked away in a closed ward. He then points out some of the other patients. Hillary has OCD. Gary, Dan and Mary are all delusional and think they are Jesus Christ.

Stiles says he wants to use the phone because he's decided Eichen House isn't safe for him or "anyone ever." A girl is talking on the payphone so Stiles waits behind her. She tells the person on the other end that she really thinks she "should tell them" because "they're going to want to know the story, the whole story" then she adds "one of them is standing right behind me."

After she's hung up and walks away, Stiles inquires and Oliver explains that her name is Meredith and that "she's a little weird." Stiles picks up the phone and finds the line is dead. Oliver says they always turn off all the phones for 24 hours after a suicide.

Exiting onto the Eichen House porch, Stiles spots Malia and starts to remind her of his role in restoring her to human form. She punches him.

They are both promptly tackled by facility staff and Stiles finds himself face down on the ground on top of a grate. It is the same grate with round openings that he remembers from his dream. Only, in the dream, he was below the grate looking up.

The orderlies are getting a little rough with Stiles until Morell shows up and puts a stop to it. Stiles explains to her about the basement.

In adjoining cells at the Sheriff's Station, Argent is waiting impatiently for Derek to listen in to the deputies and find out something helpful. Derek hears that Stilinski is out for the day.

Then they discuss the morality of what Stiles did, killing people, while under the influence of the Nogitsune. Argent compares it to the kanima situation with the but Derek says they "got lucky with Jackson" and wonders aloud what happens when you don't get lucky.

Argent tells the story of the Beserkers of ancient Europe who dressed up in bearskins in an effort to channel the bear's ferocity when they went into battle. Argent says they actually became the animals they were trying to channel and lost all humanity in the process because they were not "tempered by the moon."

He says "a couple of years ago" a family approached the Argents because their son was involved with a group of kids who were playing around with rituals, channelling the animals through their skins. The boy was completely lost and tearing people apart. It took three men and "every bullet we had" but Chris eventually put him down. He says he felt no remorse because the kid was "long gone." He says he would feel remorse for killing Stiles but not the Nogitsune.

In group therapy, Ms. Morrell is discussing guilt. She says it's a good thing, a rather mature emotion. She tries to draw Malia out questioning her visceral reaction to guilt. Malia says it makes her sick to her stomach. Morrell says it often becomes physical and is not just psychological.

While she's talking Stiles believes he sees the Nogitsune talking to one of the orderlies. Morrell calls on him for his reaction to guilt. He says it makes him nervous. Morrell interprets this as a sense of urgency saying Stiles feels an urgent need to make up for something he's done. She says those are healthy responses. Stiles again sees the Nogitsune first from the corner of his eye then sitting next to him in the group circle.

Morrell asks the group what they call someone who doesn't experience guilt. Oliver volunteers the right answer that such a person would be a "sociopath." Morrell, noticing red jagged lines on Stiles' neck, ends the group session and takes him to her office.

Stiles has a red mark that looks like lightning bolts running up his back to his neck. Morrell says it is a Lichtenberg figure which is known to appear after lightning strikes a person. She describes the appearance on Stiles after a shot of Wolf Lichen as both significant and strange. She says when the marks fade the Nogitsune will have control of Stiles again.

She gives him amphetamines to stay away, saying sleep would be the exactly what he doesn't want to do because he is vulnerable when he's asleep. She also threatens to inject him with Pancuronium Bromidewhich she says will cause respiratory paralysis. She explains that the drug is used to carry out lethal injections. Stiles realizes she plans to kill him if the Nogitsune takes over. She says she'll do what she's always done – "maintain the balance." She leaves him with a warning to "stay awake."

(In the many of the United States, the highest penalty for crime is death by lethal injection. Most commonly, three drugs are used to kill the prisoner. Pancuronium Bromide is the second drug administered because it stops the prisoner's lungs from functioning thereby starving the brain of oxygen)~~~

Stiles attempts to get down to the basement but the door is locked. Oliver says the head orderly, Brunski, has a key. Oliver suggests if Stiles want's Brunski's keys he will have to "figure out a way to trick him."

~~~

Selene steps out a shop and starts walking back to her car. She seems to be uneasy and jumpy. She walks into a back ally and pops out her claws.

"I'm warning you, I'm armed," Selene says before turning around, her eyes glowing and fangs out.

"So am I" A man in a suit says and tries to attack her but she twists his arm. She then grabs his head and jabs it against a wall. She checks for a pulse before finding the guys wallet.

"Come on, who are you working for" she mumbles to herself as she continues to search him. She finds a card. "You gotta be fucking kidding me" She mumbles as she gets up, letting the card fall to the ground. The card has a symbol on it: a rhombus with a cross through it.

~~~

In the Eichen House men's shower room, Stiles takes one of the pills Ms Morrell gave him. Looking in the mirror, he notices that Malia is showering behind him. There are some awkward moments where Stiles tries not to look at her naked body. She explains that she uses the shower in the men's room because they're hotter than in the women's. She says ever since she became human again she's constantly cold. Stiles fumbles around with some scientific explanation about a lower core temperature before she cuts him off and explains that she used to have a full-body fur coat when she was a werecoyote.

He asks why she punched him and she sarcastically thanks Stiles for invading her home, putting her on the run, and turning her back to human. She says she looked at her father every day and tried to figure out how to tell him that her sister and mother are dead because she almost ate them on a full moon. Stiles says they were just trying to help. Malia says if they want to help her they will find a way to change her back. Stiles says he might know somebody who could teach her how to change. She agrees to help him distract Brunski and get the keys.

~~~

Selene gets out of the car and is faced with a Mansion. She frowns and then licks her lips. The guards standing at the doors of the house raise their guns and start to walk forwards.

"Who are you?" One of the men asks. Selene notices he's a werewolf because of his sent and that explains why he isn't holding a gun.

"Selene Vulpes" The guard looks her up and down and then nods at an other guard. Selene smirks as she walks past them and into the Mansion.

~~~

Oliver pins Malia to the floor screaming that she's lying about the Eichen House staff drilling holes in his head. Brunski steps in to break up the fight. Malia lifts his keys and hands them off to Stiles.

~~~

At the Sheriff's station, Argent is taken to an interview room to meet with his lawyer. He is surprised to find the older Spanish speaking woman, the same woman who kidnapped Derek and Peter. She calls him "Christophe."

~~~

Stiles tries all the keys but none open the door to the basement. Brunski catches him, locks him a "quiet room" and gives him a shot of Haldol which puts him to sleep.

~~~

A woman is standing in fron of a large window with a glass in her hand. Selene clears her throat.

"Well, hello, this is an unsuspected surprise" The woman says in a bored tone after turning around.

"Cut the crap. You why did you sent someone after me?" Selene asks as she pours a glass of whiskey.

"You know you're underage right?"

"You know I don't care, right?" They stare at each other intimately before smiles form on both their faces. They place their drinks down and hug each other.

~~~

Stiles dreams he's trapped in a locker. He begs to be let out. The Nogitsune is outside banging on the door and demanding that Stiles "let me in!"

He wakes in the quiet room and Malia is there. She says she broke the lock because if she concentrates she can be pretty strong. She says there's another way into the basement, through the closed unit where they keep "the real psychos".

~~~

Selene and the woman are sitting at a table, the woman's face is filled with worry.

"A nogitsune isn't something to meddle with. You should kill it" the woman says.

"But there is still a person in there. There has to be" the woman sighs at Selene's words. "Nao, please, at least give me the scroll"

"Chīsana ōkami (little wolf), you want to help everyone. One day, that's going to get you killed"

~~~

Inside, Argent is still meeting with the mysterious woman. They're discussing the code, she says it's more than a code of behaviour, "it's a code of honor." She says it binds their families and that he can't abandon such things lightly. Argent counters asking where in the code it said his wife had to kill herself. The woman says Victoria Argent "honoured us with her dying breath." Upset now, Chris says she could have honoured her daughter by staying alive.

She says the Argent family is very complicated. He demands to know what she wants, wondering if this visit is somehow about Allison. The woman gets up and leaves without an explanation.

~~~

Stiles and Malia make it to the basement of Eichen House. Stiles points out the Japanese symbol for "self" scratched into the wall. She urges Stiles to tell her more, he says "you might not like me if you knew more." She reminds him that she is a werecoyote that murdered her whole family and promises not to judge.

~~~

Stiles and Malia are going through a bunch of old papers that were stored in the basement. They find an illustration of trephination which is what Oliver was screaming about earlier – the practice of drilling holes in a patient's head to treat depression and other mental ailments.

Stiles has Malia check the lines on his back, they're fading and almost gone. Stiles shivers at the touch of Malia's cold hands. He holds her hands to warm them and they kiss. Malia says she wants to "try something else" and removes her shirt. The pair apparently have sex, both for the first time.

~~~

"Change the body of the host?" Selene asks.

"You know what it means" the woman, Nao, replies to her questioning tone.

"But that could still kill him"

"Chīsana ōkami, you can't help everyone" Selene snorts.

"I can try"

"Stuborness really is your family's trademark, isn't it?"

"You're right about that" Selene says while getting up. "I shoud go" Nao nods and gets up too.

"Good luck, if you need anything, my door is always open" to which Selene nods.

"Tell Freya I came by"

"I will" Nao pulls Selene in for a hug. "Stay strong, Chīsana ōkami "

~~~

Spooning together on the couch, Malia has an idea. She walks over to the "self" kanji carved in the wall and raps on it with her fist. There is a hollow sound. Stiles grabs a pipe (which was just laying there, for no reason at all) and busts in the wall. In a hollow behind the panel they see a skeleton all bandaged and covered in cobwebs. Stiles says it is the Nogitsune that he keeps seeing.

Malia reaches into the pocket of the corpse and removes a photograph. Handing it to Stiles she asks if he recognizes anyone. Stiles says he does recognize "one of them." At that moment, Oliver tazes Stiles and Malia. He then injects Malia with Haldol. Oliver brings up trephination again and grabs an electric drill. Holding it aloft he says he's "going to let the evil spirits out."

Stiles is strapped down to a chair as is Malia. Oliver has a coughing fit and coughs up a handful of blood and a dead fly. He turns on the drill and moves toward Stiles' skull until a rough voice says "start with her." Oliver immediately stops and moves over to Malia. The Nogitsune is standing across the room. Stiles figures out that the creature somehow got into Oliver's head. The Nogitsune says "every Dracula needs a Renfield"

(Renfield is... I'm not even gonna try to explain who Renfield is. He's basically Dracula's puppet)

As Oliver prepares to drill into Malia's head, Stiles begs the Nogitsune to stop him. The creature doesn't relent until Stiles allows him to take control. Stiles/Nogitsune then breaks the straps restraining him, takes the drill from Oliver and knocks him out with it. He exits leaving Malia strapped to chair in the Eichen House basement.
