A group of Yakuza are gathered at their boss Ikeda's home. He is angry because his pet white wolf is sick and he grows tired of waiting for the doctor.

Just as he yells about the doctor not being there the doors open. Deaton, Reed and Cheryl are revealed with two Yakuza by their sides. They bow and apologise for being late in Japanese.

"Apologize if you can't do anything. Have you worked with wolves before?" the boss asks as Reed kneels down in front of the white wolf to take a closer look.

"Not that much, that's why he's here" Deaton explains, motioning at Reed. "What's our patient's name?"

"Yuki" the boss answers. Reed looks at the wolf's teeth, getting no movement while lifting the wolf's lip.

"Has Yuki been around some unusual plants? Something that looks like moss?" Reed asks." It would be bright green, almost neon? It's called lichen, and it's highly toxic. I need to know if Yuki has consumed any"

"He has the poison, just treat him"

"I can't, threatening him without knowing the kind could kill him. We need a sample" Reed explains.

"It's in the Garden. Shigeki, take them" the boss orders. The Yakuza look down, not wanting to go there. The boss starts to yell in Japanese before taking the trio into the Garden himself.

~~~

The garden is the same one where young Chris Argent first encountered the Oni. The lichen grows on top of the fountain where the blood fell when the Nogitsune was killed. Deaton hands a glass container to the boss, then bends down to take a sample of the plant.

"Are you not going to take it yourself?" the boss asks Reed.

"I'm afraid I can't. Just like Yuki couldn't have done. A wolf won't come near such plant" Reed explains with a grin. The boss pulls out a gun and points it at Reed.

"What have you done to my wolf?" he asks. Cheryl rolls her eyes and grabs the wrist holding the gun. She twists the wrist and it snaps audibly. That's when the Kanima venom on the jar begins to work and the Yakuza boss is left paralyzed.

"You got your wolf Lichen, now let's go" Cheryl states.

"Do you know how they used this lichen?" Deaton asks.

"They would put out meat stuffed with the lichen and broken glass that the animals would eat. The broken glass would perforate the internal organs and allow the vulpinic acid to reach them faster. Now come on" Cheryl says and walks out of the doors.

(Cheryl's explanation of how animals can be poisoned with Wolf Lichen is historically accurate according to the 1921 text Lichens by Annie Lorraine Smith.)

"Your friend is very impatient" Deaton points out as he puts the lichen in the jar.

"That's Cheryl. Now let's go poison the fox hiding in a teenage boy" Reed admits.

A sparking power line from the roof of the hospital is flying at Kira's face. It whips past her but then, like it has a mind of its own, it seems to chase her, backing her up in the parking lot. An ambulance speeds around the corner and hits the electrified line. The driver loses control and rams a fire hydrant, water sprays everywhere and begins to pool and run across the parking lot. Dazed by the impact, the ambulance driver stumbles out of the vehicle. When his foot hits the wet ground he is instantly electrocuted. Isaac and Selene arrive just in time to witness this. Selene by instinct ties to run forward to help the driver.

"Selene!" Isaac yells as he pushes her back just as the water reaches his feet. He is also felled by the electrified water.

"Isaac!" Selene yells in response to seeing him on the ground. A woman steps from a car and is electrocuted. Derek and Scott arrive just as Kira somersaults over a car and grabs the live wire. She caps the sparking end with her free hand and the power subsides as her eyes begin to glow warm amber. Mrs Yuimura exits the hospital just in time to witness her daughter's power. The moment there Kira grabs the wire Selene runs towards Isaac, not caring if she gets electrocuted.

"Hey, hey. Come on, Isaac. Don't do this to me, please. Don't" Selene starts rambling as she tries to shake him awake. Tears threaten to spill from her eyes. Derek runs over to Isaac after Kira completely stopped the electricity. "Oh my God! He isn't breathing! Someone! Get help! Now!" She starts to breathe heavily and Derek pulls her closer to him, trying to calm her down.

~~~

48 hours later, Scott is in bed fully clothed. He remembers the events of that night again. A badly burned Isaac is rushed into the emergency room. Deputy Parrish reports that Stiles' Jeep was seen leaving the hospital. Kira's mom warns her that it "is not the time" for people to see her power. Agent McCall notes that the power line was cut and warns that everyone should be looking for signs of sabotage. Derek tells Scott to tell the Sheriff what's really wrong with Stiles.

Mellisa holds a cup of tea at the kitchen table when her son comes in. She explains that they've still not found Stiles after 48 hours. She says, despite how long he's been gone, if anyone could be missing for two days then turn up and be just fine - it would be Stiles. They decide to stop by the hospital on the way to school to check on Isaac. Mellisa also tells Scott, Selene hasn't left the hospital in days.

~~~

Sheriff Stilinski is looking at a text from his son. It reads – "Am ok. Please don't look for me. Be back soon." Deputy Parrish arrives with a delivery man, he has two boxes wrapped in brown paper which Parrish explains are "printer cartridges and stuff, batteries for the next blackout." Agent McCall enters and asks if the Sheriff has had any problems with Yakuza.

~~~

Selene has fallen asleep in the hallway of the hospital. Scott shakes her awake.

"You really have been here the whole weekend"

"they won't let me in to see him, 'cause I'm not officialy family. I told them he doesn't have any"

"He has you," Mellisa says and Selene smiles weakly. "And I got a key-card"

~~~

"Be quick"

Isaac is badly burned on the side of his face and neck. Scott takes Selene's hand in his as he notices she's shaking.

"This my fault," Selene says and a sob escapes her lips. She puts her hand on Isaac's injured arm and starts to take his pain.

"It's not. Do you hear me? It's the Nogitsune's" Selene gasps in pain as she continues to take Isaac's. Her eyes glow red as Scott pulls her away. He turns her around to meet his eyes. "It really isn't"

"Everyone I love gets hurt," Selene says, her tone mearly a whisper. Scott pulls her in for a hug.

"We'll be alright. We'll all be alright" Scott whispers while looking at Isaac over her shoulder.

~~~

Later at school, Kira explains that kitsune are tricksters and have no concept of right or wrong but that Nogitsune react badly if you offend it adding that with the level of bad being perpetrated, someone really, really offended this nogitsune.

~~~

Coach blows his whistle and reminds his team that if anyone sees Stiles they should immediately report it to a teacher. He then says there is a card for Isaac on his desk. He insists that the team not only sign the card but each must write a personal message so profound and deep that it will "bring a tear coach's eye." Danny is first up to sign. The coach warns him to keep it "PG."

The twins report to Scott that they've not seen Stiles or the "Demonic Ninjas" (Oni). At that moment their werewolf hearing picks up the piercing tone of one of Chris Argent's ultrasonic emitters. They follow the sound to the basement where they find Stiles waiting. The twins attack until Scott forces them off, throwing Ethan against a locker and then growling Aiden into submission.

Stiles explains that he doesn't know what he's been doing for two days. He has a blueprint of the hospital electrical grid and a bag full of rope, wire and tools as well as a map of the Cross Country Team's running trail. The trial is the same area where Malia Tate lost her family in a car wreck and where her father put out a bunch of metal bear traps in an attempt to catch the coyote. Believing the nogitsune has used Stiles to set up booby-traps along the trail, the trio race to stop the team.

~~~

Lydia sees her mom down at the end of the hall in the school. She is talking to Peter Hale. As she draws closer Peter disappears in the crowd. When questioned, Lydia's mom says Peter claimed to be from the health department and was there to set up hearing tests for the students. He also apparently slipped Mrs. Martin his phone number to which she chirps "still got it."

~~~

Chris Argent returns home to find his door ajar and an ultrasonic emitter stabbed into the top of his office desk. Derek Hale is in the room. He knocks the gun from Argent's hand and places his claws against his neck. Chris pulls another gun and holds it to Derek's temple. Derek accuses Argent of leaving the emitter in his loft. An uneasy truce is established and the weapons are put away.

~~~

On the trail, Danny takes the lead but is passed by a gleeful Kira who suddenly realizes that she can run supernaturally fast. Stiles and Aiden catch up to Coach at the start of the trail.

~~~

Argent realizes that one of his cabinets has been forced open. Inside there is a metal briefcase, after checking it for a trap, they open it and find $150 thousand dollars. It is the money that would have come from the sale of his antique gun to Silverfinger. At that moment, Agent McCall comes in with the prosthetic silver finger in an evidence bag and says the old Yakuza is dead.

~~~

Ethan catches and tackles Danny who is confused until the weretwin says he "missed" him and starts kissing him. Scott manages to stop Kira who is still giddy with her speed ability. Stiles Coach and Aiden arrive and they manage to stop the rest of the cross country team. Stiles finds a chain under some leaves but it is attached to nothing. Coach, believing this is just another funny/weird Stilinski moment begins to berate him and steps forward into a tripwire. An arrow punctures Coach's diaphragm and he collapses.

~~~

Allison, Selene and Lydia arrive at Derek's Loft to see Peter. Lydia is about to knock when Allison stops her.

"While I think it's smart to bring us with you, I still think the rest of this is idiotic" Allison explains.

"I tried to find Stiles and let us into a mental institution. I call that a colossal failure" Lydia responds.

"That doesn't mean he can help" Selene points out.

"He's the only one offering help" Lydia replies.

"Yeah, I just can't imagine what he's gonna want for it in return" Selene reminds Lydia about Peter's reasoning.

"Fine, let's see what he wants," Lydia says and opens the door.

"The Hunter, The Banshee and The True Alpha. Ladies, come in" Peter says.

~~~

On the trail, Coach is screaming. Stiles is pushing on the wound in his stomach which has spread blood all over his shirt. The arrow is still in there and the coach is screaming for someone to pull it out. Stiles gives Scott a look indicating he should use his ability to take away the pain. Scott does so and Coach passes out.

~~~

Derek and Chris are handcuffed to a bench outside Sheriff Stilinski's office. They discuss why Stiles would want to frame them for murder. Chris says he's not entirely convinced that's what is going on and comes up with a scheme to buy more time to figure it out. He asks Derek to say that he wants Argent's attorney to represent him as well.

~~~

"They go," Peter says.

"The last time I was alone with you... I almost bled out on a lacrosse field. They stay" Lydia responds.

"Do you actually think I was trying to kill you when I bit you-" Peter starts.

"Just cut the crap and tell us why we're here" Selene cuts him off.

"I'm the spark that lit your fire sweetheart." Peter ignores Selene and she growls.

"You attacked her and nearly killed her" Allison points out, keeping her eyes and Selene. Allison knows with everything happening to Isaac Selene would love using Peter as a punchbag to let out frustration.

"Power doesn't come without a little pain or struggle" Peter replies.

"She didn't ask for" Selene objects.

"But she's embracing it now, isn't she?" Peter replies.

"How about the fact that you brainwashed her and used her to bring yourself back to live, almost driving her insane in the process"

"So that I could be here today to helping you master abilities. Isn't it amazing how things always come back full circle?"

"He's insane. We're leaving" Selene and Allison say at the same time and both ake one of Lydia's hands.

"You wanna know the truth, Lydia?" Peter asks, making Lydia stop in her tracks. "The scream doesn't give you power. All the scream does is drown out the noise, allowing you to hear what you need to. I can help you focus your hearing"

"And what do you want her to hear?" Selene asks, getting tired of Peter's games. Peter opens a box that was standing on the table. Selene snorts. "Really?" that's when she realises something and smirks. "She stole a memory, didn't she?"

~~~

Coach gets put into an ambulance and Sheriff Stilinski finally gets to hug his son. Aiden discovers wrapping paper in the back of Stiles' Jeep. Remembering that Barrow used a gift-wrapped package to deliver his bomb to a school bus, they call the school and evacuate all the kids off the busses – all but one.

Jared (the guy Stiles made throw up in the bus when they needed to stitch Scott up) is sitting near the back of the bus.

Deputy Parrish insists that he can safely get a look at what type of bomb they're dealing with because he was "certified HDT" after two years in the military.

(HDT stands for Hazardous Device Team.)

~~~

"If Talia Hale really stole a memory from you, I'm sure it was to make sure no one dies" Selene says and she looks at one of the claws in her hand.

"You don't know my sister-" Peter

"You sure of that?" Selene asks as a smirk finds it's way onto her face.

"Why else would your sister try to steal a memory from you?" Lydia asks before Peter can reply to Selene.

"If I remembered the memory, I might be able to tell you" Peter replies.

"So what am I supposed to do?"

~~~

Derek is annoyed and wants to break out of the cuffs. Argent says he could too but doesn't want to be a fugitive from the law. He convinces Derek to be patient a little while longer. While Derek agrees he says that if something happens "don't expect me to risk my life for yours."

~~~

Mrs Yukimura is waiting for her husband in his classroom. Kira is following him at a discrete distance. He enters, closes the door and retrieves a large History of the World book from a shelf. She is incredulous that he "hid them in a book" but he says it's the safest place around a bunch of teenagers because few would ever "willingly open a book."

Inside the pages have been cut to create nine slots. Each is designed to hold a single black knife. Mr Yukimura tells his wife that she needs to tell Kira "especially about this" indicating the book. He says she has already "sacrificed five." He says three of the Oni are gone then asks "how many tails are you willing to sacrifice?" She says all of them if she has to.

She then removes one of the knives, about a foot in length, all black with a rectangular hilt. She snaps the knife in two causing her husband to wince as if in pain. A pale blue light escapes the two broken pieces of the knife. She lays the pieces down and repeats the process with a second knife. She says "these Oni will be stronger, much stronger."

~~~

"Focus!" Peter orders.

"I am focussing" Lydia responds while holds Talia's claws.

"You're not. I can see the wheels spinning behind your eyes. Your hearing is attuned to a level of the universe that no one else can hear. But it only if you're listening"

"I am trying"

"Try harder!" he yells while coming closer to Lydia. Allison whips out the electroshock/cattle prod device. He pops his claws. "Your aunt had one of those. Aunty Kate" Peter taunts.

"Stop it. Both of you" Lydia says.

"Didn't do her much good as I ripped her throat out, did it?" Peter continues his taunts.

"She didn't shove it up your a-" Allison starts but gets cut off by Lydia.

"Stop it!" Lydia repeats at a screaming tone while throwing Talia's claws so hard they stick into a wooden beam like darts. She begins to hear whispering.

"Lydia? Lydia do you hear something?" Peter asks.

"She might, if you shut up" Selene points out, her eyes never leaving Lydia who walks closer and closer to the claws. Finally she turns, her expression shocked.

"You're not just an uncle."

~~~

Parrish enters the bus and tries to keep Jared calm while he checks out the wrapped package. Jared is sweating profusely and Parrish admonishes him not to throw up. He keeps talking to distract the boy explaining that he is 24 but still looks young and that anyone can look young if they eat right and exercise but that it really comes down to good genes. While he continues with this patter he has managed to snip the ribbon from the box. He slowly pries open the lid and looks inside.

Parrish radios to the Sheriff that it is not a bomb but that something else was in the box. He then walks to the front of the bus and holds up the nameplate from Sheriff Stilinski's desk. The sheriff remembers the packages delivered to him that morning, realizes that the bomb is at the station.

~~~

The Deputies at the station are in a panic. They hastily unlock Argent and Derek's handcuffs and run for the door. Derek seems to hear something coming from the box on Stilinski's desk and yells for Argent to get down then covers him with his own body to shield him from the blast.

~~~

At the school, Mr Yukimura and his wife watch as the sunsets. At the Nemeton, fireflies erupt from the magic stump. These are slightly different than the ones seen before. There is a blue, slightly metallic, sheen to their wings.

Inside the Sheriff's Station, Stilinski is calling for an ambulance reporting "multiple officers down." Derek's back is riddled with glass shards as Argent helps him stand. Derek says he's okay, Argent points out that Derek saved his life.

Stiles and Scott kneel by one badly injured deputy. Stiles encourages Scott to take the dying man's pain, which he does until the man expires. Kira runs in and tells them that the Oni are coming.

~~~

"I said, I don't know. I don't know its name. If it's a boy or a girl. If it's some mutated wolf baby" Lydia denies as she walks backwards while Peter steps forwards. Both Peter and Selene know she's lying because of her hearbeat.

"You're lying. Tell me what you know" Peter says and grabs her shoulders. Selene growls. "Ow really?" Allison jabs him in the back with the cattle prod and he is left writhing on the floor.

"No" Selene says with a smirk and takes Lydia and Allison's hands in hers, pulling them away from the loft.

~~~

Stiles, Scott and Kira discuss to take Stiles to the Vet Clinic since it is lined with Mountain Ash and will offer some limited protection from the Oni.

~~~

Selene is sitting in the back of Lydia's car looking at both Lydia and Allison's phone.

"I got mine, did you get yours?" Allison asks.
