The students at Beacon Hills High School seem to have suffered a rash of hand injuries. All are wearing bloody white bandages on their hands. Edgar moves quickly but nervously down the hallway and into the library. He's cornered by Aaron and Gabe who grab him and cut his hand with a scalpel. Aaron says everybody has done it. Edgar protests that he's "not one of them," but Aaron cuts his hand anyway. He runs from the library. Aaron calls Gabe off and says he'll go after Edgar himself. The other students do their best to ignore what's happening.

In the locker room, Edgar washes the blood from his hand, and there is no sign of injury. Aaron is suddenly behind him. He demands to know what Edgar is. The boy's eyes flash yellow, and he says he's a werecoyote, his whole family too. Aaron wants to know what "else" he is, saying he's looking for someone who "can do more than just shift, someone like me." He grabs Edgar's wrist, and something under the skin moves down Aaron's arm and into Edgar's. The veins of his arm turn a dark red as whatever is in him crawls up the arm, into his neck and head.

FBI Agent McCall is questioning Nolan in Tamora Monroe's office. McCall says that Elias, Jiang, and Tierney escaped police custody "last night." Monroe adds that they injured a deputy, but McCall says he's heard the officer's wounds were self-inflicted. McCall wants to know if Jiang's been in touch with Nolan since they knew each other. Nolan explains that they're no longer friends. Seeing the student is in distress, Monroe ends the interview.

She chides the agent for harassing a student. He counters that she put a gun in his hand. She says she's teaching him how to protect himself. He says Nolan isn't in danger, the missing Jiang and Tierney are. She reminds him that the missing pair are the real killers. She then speculates that, because McCall doesn't have FBI backup, his bosses either don't believe there's a problem, or he hasn't told them "exactly what you're investigating."

~~~

Monroe exits her office to find a girl leaning against the wall next to the door. "Ah, the FBI, always getting involved with things they don't quite understand,"

"Can I help you?" Monroe questions.

"The name's Diana Aquila. I'm sure our mutual friend has told you about me,"

Realization passes over her face. "He has,"

Diana pushes herself away from the wall. "Good. My brother and I find your cause to be inspiring. Let us help,"

A smirk forms itself onto Monroe's face. "Gladly,"

~~~

Nolan runs to the locker room to catch his breath. He hears Edgar moaning for help. He finds the other boy laying on his back. There are small moving bumps under his skin. Suddenly his eyes, nose, and mouth erupt with thousands of spiders that quickly obscure his face.

~~~

Gerard meets with Agent McCall and someone from the US Bureau of Alcohol, Tobacco, and Firearms. The old hunter presents them with files he says are his "FFLs" or Federal Firearms License forms. He says they're all up to date. McCall examines the tag on one of the cases; it says 625, Stock No. 711432, Serial NO. AA-612243, Brand Name Colt Remington AR-15, Type Semi-Auto, Caliber/Gauge .223, Barrel Length 20". Gerard says the first number is the price and offers a law enforcement discount of 10% off to Agent McCall.

Looking around at the high shelves stacked with guns and ammo, McCall asks why Gerard has so much firepower. The old man counters that he's a federally licensed wholesaler and some people like to feel safe, "My staff and I sell peace of mind." McCall says Gerard's EDD (California Employment Development Department) roster says he has 30 employees, but there are enough guns in the room to arm 3000 people. Gerard says selling guns is the way he makes his living.

McCall asks about his security arrangements. Gerard explains that they have a dozen employees on-site during business hours. He says cameras in the warehouse keep everything under a 24 watch while their surveillance room monitors landline cellular and online communications within the building at all times. While the ATF agent is fine with all Gerard's paperwork, McCall presses further. He says Gerard has a lot of firepower for such a small market. Gerard says business is booming.

~~~

In the locker room, Nolan apparently sought out Tamora Monroe and Gabe after discovering Edgar's body. The boy is still alive, choking on the floor. Monroe tells them to get rid of it. Nolan points out that he knows the boy from his trig class. She says it's not human and instructs that "one of you put it out of its misery." Gabe asks how they're supposed to do that to which she replies "Just do it." Gabe chokes the boy until he stops moving. He then looks stricken at what he's done. Nolan seems about to pass out. He barely registers when Monroe tells him to help Gabe get rid of the body. She tells him that Gabe just proved she could count on him and asks the same of Nolan. He looks completely dazed and out of it.

~~~

Later in class, several students have their hands bandaged. Nolan is staring at his exam paper without comprehension. He looks up and sees Mason carrying an armful of blankets down the hall. He follows him.

In the parking lot, Mason dumps the blankets into the back of Lydia's car. He sets the SatNav to take him to Hill Valley Zoo. It is apparently only 4.1 miles from the school at 7610 White Ave, Beacon ... The route takes him along Cyclone Street for 3.6 miles and then half a mile on White Avenue.

Nolan watches as Mason pulls away from the school. He's phoned the hunters claiming he's found Scott's Pack. He follows Mason at a laughably close distance. Liam calls and asks if the plan worked. Mason says it did. Liam tells him to be careful. The SatNav tells Mason to turn right in one mile onto Oak Avenue even though that street is not on the route listed at the beginning of the trip.

Liam and Theo are waiting for Mason at the entrance to the Zoo. They unload the car and Mason offers to come with them. Theo says Nolan's friends shoot to kill so, no. Mason says Lydia would kill him anyway if he damaged her car. Liam tells him not to worry about it because Nolan will do the rest.

~~~

Outside Gerard's fortified arms warehouse (Teen Wolf HQ with some CGI assistance), Lydia, Argent, Scott, and Malia and Liz and Selene in another car are waiting for the hunters to leave and follow Nolan to the zoo. Lydia gets a text and tells the others that their plan worked.

"Wait," Selene warns from the car radio. "There are still too many heartbeats inside."

"I hear them too," Scott confirms.

"How many?" Argent asks.

"Ten?"

"More," Malia corrects.

"Are we breaking in, or not?" Lydia asks.

"Not. The armory should be empty by now," Argent replies.

Malia scoffs. "We can take down a few Hunters if we have to."

"We're dealing with a dozen well-armed Hunters who have orders to kill us on sight," Liz reminds them.

"Then how are we supposed to get inside?" Malia asks.

~~~

Two hunters arrive at the zoo. Nolan is worried that they only sent two. He warns them that they're not just facing a pack because "there's an Alpha and a Banshee, they're all here." The hunters see no one. Nolan gets defensive and explains that he saw Theo and Liam bringing a carload of food and supplies to the zoo with at least "six sleeping bags."

Hidden inside the Zoo, Liam and Theo are worried that they only sent two hunters. They were expecting 20 for the plan to work, but since they don't believe Nolan, they didn't send everybody. Theo starts shouting. He fakes a shouting match with an invisible Liz about Liam. He then punches Liam and shouts to invisible Scott too. The hunters hear the ruckus and move to investigate. Theo punches Liam again. Theo yells that Liam is only good in a fight when he's angry, which, of course, just makes Liam angry.

~~~

Chris Argent begins to crank his SUV to leave the parking lot at Gerard's base. Malia snatches the keys from the ignition saying that as long as Gerard thinks they're gone, it's a good plan. Lydia points out that it's their only plan. Chris says the plan has failed, but Malia is optimistic.

The windshield begins to crack in front of Lydia. She zones out what the others are saying as she examines the finger-length crack. It begins to spread out like a spider web.

Chris points out that they have 10 minutes until Gerard's people notice their vehicle as suspicious.

Lydia is still zoned out, and the web of cracks continues to grow. Scott snaps her out of it, and the windshield shows no signs of damage. Chris again says they should call off the mission. Scott believes Jiang and Tierney are "missing" and says they need to get into Gerard's warehouse because the hunter is always one step ahead. Chris argues that they're too exposed. Malia sees potential in the fact that they still have 10 minutes.

~~~

Theo's nose is bloody, and Liam's shirt shows claw marks. He asks if they need to keep going. Just then, a hunter below them says they need to call for backup. Liam points out that Theo ripped his t-shirt. Theo counters that Liam broke his nose twice. He says "It healed, and you broke it again." Liam punches him in the nose again.

~~~

Scott decides that he should lure the hunters away so they can get inside the warehouse. Malia reaches over him and locks his door.

"We need a new plan," Scott protests.

"Not a dumb one," Selene counters.

"I'll bring the thermite charges,"

"One, we need them for the armory. Two, what are you going to do? Blow them and yourself up?"

"Guys..." Lydia and Liz notice the cars leaving.

"How about using the tunnels?" Malia offers.

"We could get underneath the building, but we'd still need to sneak in undetected," Argent points out.

"Guys..." Liz, Selene and Lydia try to draw their attention.

"The ventilation system?" Scott tries.

"Same problem."

"They're leaving!" Liz shouts and Selene flinches from next to her.

~~~

"There's still three of them, and it's been half an hour," Liam informs.

"Don't blame me! You're the one who picked the abandoned zoo. The hell are we doing in this place, anyway?" Theo counters.

"Because it's like Mykonos."

"Like what?"

"The Greek island. In the city, they built these long, narrow, winding streets that all meet up with each other. Invaders would get lost in them, like they were in a maze trying to figure out which way to go." Theo gives Liam a surprised look.

"What? Liz likes Greek culture and I think it's cute when she rambles about it,"

"I suppose you do pay attention to her sometimes then,"

"What's that supposed to mean?"

"Really?"

"What?"

"You mean you still haven't figured it out?"

"Just tell me!"

"She's in love with you, you idiot!" Liam jumps back with a start.

"Really?" It was basically a whisper as a small smile settled onto his face.

"Good to know that even when we're most likelygoing to die, you can still think of playing with her feelings,"

"I don't- I've never-"

"Really? I don't know how you didn't notice her mood going sour everytime you stuck your tongue down Hayden's throat!" Theo's anger suddenly subsides as he notices the heartbeats. They both turn to see the hunters arrive. Theo starts to walk away but Liam continues to stare.

"Hey, let's go. We're supposed to be decoys, not target practice. You still working on that anger?"

"I'm fine," Liam says tersely.

"Well, you can be angry at Nolan and stay alive. Come on." Liam still doesn't budge. "Fine. Get caught."

~~~

Agent McCall is demanding that his ex-wife tell him where their son is. Melissa says Scott told her not to tell his father. He presses her, pointing out that Gerard has enough firepower to "arm a small country." He says he can't call in the FBI. Melissa says it's too late now and tells her ex not to worry because "you did your job. Now it's Scott's turn." She points out that he's known about the supernatural for about five minutes, while they've been at it for a lot longer. She says "these kids can handle it" and are best at "saving our asses." McCall questions if Scott has a plan, Melissa says he does.

~~~

Argent, Lydia, Liz, Scott, Selene and Malia break into the warehouse. Argent knocks out one of the surveillance cameras with a paintball gun while Selene, Scott and Malia knock out the guards. Argent says he thermite should take care of the weapons, and reminds Scott to be clear of the scene before they detonate.

Argent takes out the guy in the surveillance room with the butt of his rifle. Selene takes out the one remaining guard in front of the armory door. Lydia, Liz and Chris watch via the camera feeds. Lydia hears a gunshot.

"Did you hear a gunshot?" Lydia asks. Argent and Liz share a look.

"No, I didn't hear anything." Argent replies.

She then hears shell casings dropping the floor. "I heard shell casings. I saw your windshield crack, and then I heard it shatter." She sighs. "I think you were right. We should've called this off."

~~~

Gerard hands Nolan a crossbow and tells him to take the south side of the zoo. He says the boy should shoot to kill. Nolan agrees and walks into the zoo. Monroe points out that Nolan could get killed. Gerard is fine with that saying, "Hopefully he takes one of them with him."

~~~

Lydia hears another gunshot and more invisible shells hit the ground. "We all have to get out of there."

"Do that, and we lose our chance," Liz points out.

"Scott, Selene and Malia could die. It's not worth the risk,"

"Ten minutes ago, I would've agreed, but right now, we're in it, and we need to weigh the risk versus reward carefully. If we stay, we could succeed. If we go, we know we won't get another chance. Since one risk is known, and the other unknown..." Argent explains.

"We go with the known," Lydia relents. Argent opens the door.

~~~

Scott, Selene and Malia enter to find the shelves empty. All the weapons and ammo boxes are gone.

"Where are all the guns?" Malia asks.

"Goddammit!" Selene curses.

"They knew we were coming," Scott realizes.

~~~

Several well-armed hunters spread out around the zoo. Liam and Theo watch Nolan from behind a concrete wall. Theo points out that the boy will see him unless he hides better. Liam refuses. Theo says he doesn't plan to die just because Liam wants payback for the beatdown Nolan and Gabe delivered earlier. Theo finally pulls Liam away.

Liam demands that Theo release him. His eyes flash yellow. Theo wonders what's going on with the young beta. He says his reckless behavior can't be just because of Nolan. He says something about the Zoo is triggering Liam. He wonders if it's the hunters, the cages, the heights. Liam says he's fine and asks why he cares anyway. Theo says he's gonna have to be the one to break the news to Liz. At the mention of Liz Liam seems to regain some of his senses.

Nolan finds the pair and calls out to the other hunters. Liam's senses disappear again and he tackles the young hunter. They both tumble off the edge of the zoo enclosure.

~~~

"Guys, get out of there now," Argent announces over the intercom.

"Let's go before they all get back," Malia agrees and she and Scott start to leave.

"Selene?" Scott suddenly notices the girl has moved.

"That scent..." she mumbles.

"It's Elias," Malia realises.

"Guys, you need to leave now!" Argent urges.

"Help me with this," Scott says and the three of them start to pull at the door.

"No, no, no! Don't open that door!" They open the door. An alarm sounds on the control board, and the doors to the armory close and lock.

~~~

Gerard and Monroe locate the supplies Theo and Liam planted in the zoo. Monroe says someone has triggered the "armory failsafe" and she can't reach anyone there. She says it's suspicious, but Gerard says it's not worthy of his time. He already knows it's Scott and Selene. She questions why they're still there playing hide and seek when it's obviously a ruse. Gerard says he wants to kill Scott's beta and drop his body at the Alpha's feet. He explains that the relationship between beta and alpha is like parent and child. Taking out Liam will break Scott and Selene is already close to breaking. Without their Alphas, the whole Teen Wolf Pack falls apart.

~~~

"Nope. Everything's shut down. They're locked in, and we can't do anything about it," Argent concludes.

"What's this?" Lydia asks pointing at a flickering light.

"A motion sensor."

"What does H-2100 mean?"

"'H' stands for halon. It's a fire suppression system. It'll pull all the oxygen out of the room to put out a fire," Liz answers. Then she frowns. "How does a motion sensor even detect a fire that doesn't make sense,"

But Lydia was still concerned with what she said before that. "All of the oxygen? How long can a Werewolf hold their breath?"

"I think we're about to find out," Argent admits.

~~~

Selene explores the room where they smelled Elias. Inside they find a map with red dots marking northern California, Greenland, western Europe, Egypt (or Sudan), China, and Siberia.

"Nemetons," she mumbles to herself before turning to the right. A sob rips itself from her mouth.

"Where's Elias?" Malia asks. Scott stares at the display and Selene's broken form.

"He's here," she chokes out. "It's all that's left of him,"

Inside the case is a piece of skin with a tattoo depicting stacked rocks, the pack symbol for Satomi Ito's pack. Next to it is a hand with the claws still prominent. Above it are two wolf ears.

Outside this room, a red laser begins to sweep across the warehouse. Malia is about to rush out of the room and into the beam, but Scott pulls her back.

~~~

Nolan is there with the crossbow. Liam is all fangs and glowing eye. Nolan says "She wants me to kill you. She'll kill me if I don't" Liam lunges at him, rips away the weapon, and begins punching the wall next to Nolan's head until his hand is broken and bloody. Liam looks as though he might claw Nolan, but Theo punches Liam and knocks him unconscious. He tells Nolan to run.

~~~

Chris explains that the communications system is shut down and the armory is soundproof. Chris finds a pipe that leads into the room and uses it to communicate, telling Scott and Malia to avoid the sensors. The first beam, about a foot off the floor, continues to sweep back and forth. Another beam, at about five feet, begins to sweep across in the opposite direction.

Scott and Malia manage to avoid both beams as they jump up onto one of the racks that formerly held firearms. They land with Malia on top of Scott. She rises to get off him just as the beam sweeps their way. Scott pulls her back down.

"And why exactly did you do that?" Selene asks at their unnecessary risk.

"This is..."Malia begins.

"...Uncomfortable?" Scott asks

"No."

"Yeah. Uh... I mean, I should probably do something."

"I've got an idea."

"Okay..."

"Uh, it's kind of a plan."

"Sounds great!"

"You don't even know what it is yet." Malia props herself up.

"Well, I mean, it's great that you have a plan." A beam passes over them again and Scott pulls her down again.
