"Derek, Max wants to take me on a moonlit walk of the Preserve." She said to the Alpha over the phone.

'And you're telling me this because…' The Alpha asked the beta rolled her eyes.

"So you know in case I need you. You know, there is an Alpha pack running around." She said and she could hear Derek sigh.

'I'm still not sure why you're telling me… You have Max with you.' He said and she could hear something different in his voice.

"Are you… Are you jealous Derek?"She asked, a small smirk on her face. The man scoffed.

"Jealous? Of him? I don't think so. Why would I be jealous of him?" He said quickly and maybe a little too forced.

"Because, maybe… just maybe… you don't dislike me as much as you say you do." She said, shifting her weight onto the other foot and putting her free hand on her hip.

'I don't know what the hell you're talking about…' She could hear the growl in his voice. She smirked again but before she could say anything, the Alpha continued. 'Howl if you have any trouble.' She said before he hung up the phone. She rolled her eyes before looking down at the phone. Maybe those feelings she has for Derek weren't so misplaced after all…

They walked down the path, holding hands. It wasn't a full moon, more of a three-quarters moon, which provided enough light that they didn't need a flashlight. The walk was silent for a little while before Max spoke. "I really like you Sophia." She smirked.

"I know." He turned to her with a raised eyebrow and a smirk of his own.

"You know?" He asked and she nodded her head. He wrapped his arms around her waist and pulled her to him. She laughed softly and wrapped her arms around his neck as he pressed a kiss to her lips. She had noticed how far they walked, it was pretty far from the cars and it was a school day tomorrow.

"Hey, we need to head back, we have school tomorrow." She said, leaning her forehead against his jaw.

"Just one more thing." He said, pulling away from her.

"What?" She asked playfully. He smiled.

"Close your eyes." She didn't hesitate; he'd never given her a reason not to trust him. She felt the back of one of his fingers running down the side of her face before she felt something off around the hinge of her jaw. It felt like the back of a claw. She peeked his eyes open and jumped in shock. Max's once brown eyes were now red… Alpha red. He clicked his tongue, grabbing her around the neck. "You should have kept your eyes closed. It would have made this so much easier." She glanced behind her when she heard someone. A tanned woman came around a tree; she had long black hair with her own pair of Alpha eyes. She was barefoot, Sophia noticed, with large claws on each toe.

"Finally, I thought you would never bring one of them." She said, walking closer to them.

"Sorry Kali. She was so much fun to play with I decided to take my time besides, she never would have followed me if she didn't trust me." He said with a smirk, tightening her grip around Sophia's neck. She couldn't howl and she knew for sure she couldn't reach her phone.

"Yeah well, that's great but when it comes to eliminating your enemies, you need to do it fast. Learn how to be an Alpha." The woman, Kali, growled at him and he rolled his eyes. She was right; he was a young Alpha, maybe just now getting the hang of his Alpha abilities. Sophia tried to take in a deep breath as she threw her leg up, catching Max in the chin, causing him to let her go. She turned and kicked out at Kali, hitting her in the head as well. She turned and began running back to the cars, she was about to howl when she was tackled from behind. She rolled onto her back and saw Max above her.

"It's too bad. We could have been so good together." He raised his claws into the air and Sophia bucked her hips hard, knocking him off balance. She extended her own claws and slashed him across the chest before rolling him off of her. She ran again, only to be stopped by Kali trying to kick her in the head. The claws on her feet were bad news. Sophia ducked a couple of times before Kali managed to slash her across her stomach. Sophia held her stomach as turn to go in the opposite direction. Max grabbed her from behind by her hair and Sophia elbows him in the face and when he didn't let go, she turned quickly and slashed wherever she could, it just happened to be his throat. Max let her go, gagging as he held his throat. Sophia and Kali watched as the boy stumbled, glaring right at her. Sophia glanced at the woman before turning and running to the cars.

She then realized just how far Max had taken her out away from the road. She got into the Challenger quickly and locking the doors behind her. She put the keys in the ignition before peeling out onto the main road and making her way home. When she pulled into the driveway, it was almost two in the morning. She had driven around for a while, giving her wounds a little more time to heal. She cut off the car and looked down at her wounds, they were almost completely healed but they were healing slowly. She sighed as she got out of the car and decided to climb up to her window. It was quick and graceless but she made it. She peeled out of her clothes and took a warm shower, watching the water run pink with the blood leaving her skin. She should have known that Max was too good to be true, she'd never had a boyfriend before and Max was seemingly perfect, of course she'd fallen for him quickly. She turned off the water and wrapped herself up in one of her fluffy, dark towels so it didn't leave a blood stain.

She changed into her pajamas before climbing into bed and going to sleep. Her sleep was dreamless and she woke up around five in the morning when her phone went off.

From Big Bad (4:58 am)

We all need to talk. Come when you get the chance if you wanna miss school. It's important.

Sophia rolled out of bed and checked her wounds; they had all healed overnight, which was a good thing. She walked over to the mirror and looked at her reflection. She took in a deep breath and closed her eyes before reopening them.

Sophia was sitting on the table beside Derek as he read a book. Isaac was pacing by the windows… or the wall of windows. "You know, I'm starting not to like this idea. It sounds kind of dangerous. You know what, I definitely don't like this idea, and I definitely don't like him."

"You'll be fine." Derek said, glancing up from his book.

"Does it have to be him?" Isaac asked the Alpha.

"He knows how to do it, Sophia and I don't. Be more dangerous if either of us tried doing it ourselves." Derek said to the beta.

"You know Scott doesn't trust him, right?" Isaac said to Derek as he picked up a book of his own, turning it in his hands. "You know personally, I'd… I'd trust Scott."

"Do you trust me?" Derek asked, looking at the boy.

"Yeah." Isaac said after a moment's pause. Derek turned back to his book. "I still don't like him."

"Nobody likes him." Derek said and Sophia snorted. The door to the loft slid open nosily, causing all three werewolves to look up.

"Boys and girl." Peter said before walking deeper into the loft. "FYI, yes, coming back from the dead has left my abilities somewhat impaired, but the hearing still works. So I hope you're comfortable saying whatever it is you're feeling straight to my face." Peter had a smirk on his face.

"We don't like you." Derek said, throwing the book down on the table beside Sophia. He stood up. "Now shut up and help us." Peter looked from Derek to Sophia and Isaac.

"Fair enough." He extended his claws. Sophia jumped down from the table and moved the chair Derek was sitting in to the middle of the room. Isaac sat down and waited for Peter. Derek sat down on the coffee table right off to the side and Sophia sat down beside him. "Relax. I'll get more out of you if you're calm." Peter said to Isaac as he walked around him. Derek and Sophia watched silently.

"How do you know how to do this, again?" Isaac asked.

"It's an ancient ritual used mostly by Alphas, since it's a skill that requires quite a bit of practice." Peter answered, making little measurements with his hands. Isaac looked over at his Alpha and pack mate before looking back at the loft door directly in front of him. "One slip and you could paralyze someone or kill them."

"But you've had a lot of practice, though, right?" Isaac asked the older man, turning to look at him.

"Well, I've never paralyzed anyone." Peter said, smiling down at the beta. Derek brow furrowed as he glanced at Sophia before looking back at the pair.

"Wait, does that mean that you…" Before Isaac could finish, Peter drove his claws into the back of his neck. Isaac grunted and grabbed both of Peter's wrists in his hands while Peter through his free arm over Isaac's chest to keep him in the chair. Derek raised his head, watching them closely. Peter threw his head back, grunting before he looked forward again. Isaac shifted hard in the chair, throwing his legs out and trying to shift to the side but Peter held him tight. Derek jumped up but Sophia grabbed his arm, holding him beside her.

"Wait, I see them." Peter said, his eyes unfocused as he looked around the room. Peter let Isaac go, the beta leaning forward in the chair panting while Peter threw himself back into the table behind him. Peter glanced back at the beta before walking off to the side.

"What'd you see?" Derek asked his uncle while Sophia slipped by him to check on Isaac.

"It was confusing." Peter said, still panting slightly. "Um, images. Vague shapes." Peter was stumbling all over his words, his hands clenching and unclenching.

"But you saw something." Derek didn't phrase it like a question.

"Isaac found them." Peter said.

"Erica and Boyd?" Sophia asked, looking at the older man.

"I barely saw them. I mean, glimpses." Peter said again.

"But you did see them." Derek said again.

"And worse." The former Alpha said quietly.

"Deucalion." Derek knew exactly. Peter looked from his nephew to Isaac. Derek sat back down on the coffee table.

"He was talking to them. Something about time running out." Peter said.

"What does it mean?" Isaac asked.

"He's gonna kill them." Derek said, rubbing his hands together.

"No, no, no, no, he didn't say that." Peter said quickly. "He did make them a promise that by the full moon that they'd both be dead."

"The next full moon?" Derek asked. Sophia looked at Peter before looking at Derek.

"Tomorrow night." She said with one hand on Isaac's arm to take the pain.

"I don't see anything." Derek said while looking at the bruises on Allison's and Lydia's arms.

"Look again." Scott said, turning to the Alpha. Sophia glanced at Stiles, who was sitting on the desk next to the one she was sitting on.

"How is a bruise going to tell me where Boyd and Erica are?" Derek asked everyone in general.

"It's the same on both sides." Scott told him. "Exactly the same."

"It's nothing." Derek said in a monotone voice.

"Pareidolia. Seeing patterns that aren't there." Lydia said and Sophia noticed that Derek and Allison were having an all-out staring contest. "It's a subset of apophenia."

"They're trying to help." Scott said to Derek.

"These two?" He asked. "This one, who used me to resurrect my psychotic uncle. Thank you. And this one, who shot about 30 arrows into me and my pack."

"Okay, alright, now come on." Stiles said from where he and Sophia were sitting. "No one died, alright? Look, there may have been a little maiming, okay, a little mangling but no death. That's what I call an important distinction." Derek turned to Stiles.

"My mother died." Allison said quietly.

"Your family's little honor code killed your mother. Not me." The Alpha said back.

"That girl was looking for Scott. I'm here to help him, not you." Allison said.

"I do recall your dad saying the same thing." Sophia said as she slid off of the desk and walking to stand between Derek and Scott.

"You wanna help? Find something real." The Alpha said before turning to leave. Scott followed him. They had a quick conversation before he left. Sophia stayed since they were at school anyway. She didn't need her bag since all of her books were in her locker anyway.

XXX

"Okay, what would a pack of Alphas want with Erica and Boyd?" Stiles asked as they walked.

"I'm not sure it's them they want." Sophia said as they continued to walk.

"Okay, what, like Derek? Like they're recruiting?" Stiles asked the girl before she caught a scent. Scott must've caught it too before he turned to watch as the two new twins walked by them. "Hey guys, you coming?" Sophia nodded, grabbing Scott's jacket as she went to her next class.

From Scotty (1:35 pm)

Come to Deaton's after school. Going to try and help Isaac remember.

A few hours later and Sophia, Derek, Scott, and Stiles all poured bags of ice into a bath. "How slow does his heartrate need to be?" Scott asked. Sophia glanced at the vet before touching the water with her finger. She pulled it back quickly and put it in her pocket to warm it up. She was a wuss when it came to the cold.

"Very slow." Deaton answered.

"Okay, well, how slow is very slow?" Derek asked, bending at the waist to leaning against the metal tub.

"Nearly dead." Deaton said and all of the werewolves looked up at him. Isaac touched the water and inhaled sharply.

"It's safe, though, right?" Isaac asked, looking up at the man.

"Do you want me to answer honestly?" Deaton countered with his own question.

"No. No, not really." Isaac said, deciding to leave well enough alone. Everyone turned when a rubber glove snapped. Stiles had one of the gloves on that comes all the way to your shoulder. They all watched him unamused.

"What?" He asked and both Derek and Sophia raised an eyebrow at him. He pulled the glove off quickly and threw it aside. Isaac stood up and took in a deep breath.

"Look, if it feels too risky, you don't have to do this." Derek said to his beta. Scott and Sophia nodded in agreement. They all wanted Isaac to be 100% sure about this. Isaac took off his shirt and set it aside. He stepped into the bath before sitting down. He gasped as he settled. Sophia was at his head, Scott on her right, and Derek on her left. Sophia rolled up the sleeves on her long sleeve, black and gray striped shirt. Both boys put a hand on Isaac's shoulder while Sophia leaned over and wrapped on lightly around his neck. They glanced at each other before they pushed him under the water.

XXX

Seconds later, he came up out of the water, pushing against the three other werewolves' strength. "Get him back under." Deaton said and the three pushed him back under, holding him while he struggled. Isaac came out of the water again, trying to get out. "Hold him!"

"We're trying!" Derek yelled to the vet before turning his attention back to the beta. They were able to push him down once more and slowly, he stopped struggling. Scott and Derek let him go while Sophia shifted her hand to the back of his neck, slowly bringing him to the surface so he could breathe. He inhaled right away. Deaton shushed everyone.

"Now, remember, only I talk to him." He said quietly. "Too many voices will confuse him and draw him out." Derek and Scott kept a light hand on both of Isaac's shoulders, making it so only his head out of the water, being held up by Sophia. "Isaac?" The vet called his name. "Can you hear me?"

"Yes." Isaac said. "I can hear you."

"This is Dr. Deaton. I'd like to ask you a few questions. Is that alright?" Deaton asked.

"Yes." Isaac answered.

"I want to ask you about the night you found Erica and Boyd." Slowly, Derek and Scott let go of him but Sophia kept her hand under Isaac's head. "I want you to remember it for me in as vivid detail as possible, like you're actually there again."

"I don't wanna do that. I don't wanna do that." Isaac repeated, getting a little restless.

"Isaac, it's alright. Just relax." Derek and Scott had to grab Isaac's shoulders again while Sophia gripped the back of his neck harder and placed her other one on the middle of his chest. "They're just memories. You can't be hurt my memories." As all of this is going on, there was thunder outside and the power in the clinic was flickering.

"I don't wanna do that." The beta said again.

"It's alright." Deaton said to him.

"I don't wanna do that."

"Relax." Deaton said to him and Isaac grunted. "Relax." Slowly, Isaac began to calm down and settle again. "Good." Scott and Derek removed their hands and Sophia removed the one. "Now, let's go back to that night. To the place you found Erica and Boyd. Can you tell me what you see? Is there some kind of building? A house?"

"It's not a house. It's a stone." Isaac said, his brow furrowed in confusion. "I think marble."

"That's perfect. Can you give me any other descriptors?"

"It's dusty, so empty."

"Like an abandoned building?" Isaac didn't answer and there was another clap of thunder before the power began to flicker again. "Isaac?"

"Someone's here." He said, grabbing Scott's arm. "Someone's here."

"Isaac, relax."

"No, no, no, no. They see me, they see me!" Isaac began to struggle again. Scott and Derek hold him down again. He screams.

"Just memories. You won't be hurt by your memories. Just relax." Deaton said in a calm, soothing voice. Isaac calmed down again, releasing Scott's wrist. "Good. Now tell us what you see. Tell us everything."

"I hear him. He's talking about the full moon." Isaac said as he opened his eyes. "About being out of control when the moon rises."

"Is he talking to Erica?" Deaton asked.

"I think so, I can't… I can't see her. I can't see either of them."

"Can you hear anything else?" Sophia glanced at the other werewolves. They looked up at her before looking down at Isaac.

"They're worried… worried about what they'll do during the full moon. They're worried that they're going to hurt each other." Derek shook his head.

"If they're locked in together on the full moon, they're going to tear each other apart." Derek said quietly. Scott and Sophia nodded.

"Isaac, we need to find them right now." Deaton said to the blonde beta. "Can you see them?" Isaac tilted his head on Sophia's hand.

"No."

"Do you know what kind of room it is? Is there any kind of marker? A number on a door? A sign?" Isaac suddenly sat up gasping. Sophia jumped back, not expecting it. Derek grabbed the beta.

"They're here." He whispers. He repeats it a few times.

"It's alright. Just tell us…" Isaac began to panic and Sophia walked over to him, dipping her hand back into the water behind Isaac's head, giving him a firm squeeze on the back of his neck.

"This isn't working. Isaac, where are you?" Derek said to Deaton and then to the Beta.

"I can't see them. It's too dark!" Isaac said to him.

"Tell me where you are." Derek said.

"I can't see!" Isaac says back.

"You're going to confuse him." Deaton said to the Alpha.

"Isaac, where are you?" Derek repeats to the beta, ignoring the vet. "Just tell me where you are."

"His heart rate… he could go into shock." Deaton said to Derek.

"Derek, let him go!" Scott yelled to the Alpha. Sophia let Isaac go.

"Derek, enough!" She said to him.

"Isaac, where are you? What did you see?" Derek yells to the beta.

"A vault! It's a bank vault!" Isaac yells. "I saw it! I saw the name!" Isaac yells as he sits up, fully awake from the whole ordeal. He got out of the ice water and was wrapped in a towel by Deaton. Sophia pushed Derek out of the way with a glare before leaning in close to the other beta, trying to share her body heat. "It's, uh, Beacon Hills First National Bank. It's an abandoned bank and they're keeping them locked inside the vault." Everyone fell silent. "What?"

"You don't remember what you said right before you came out of it, do you?" Stiles said to him. Isaac shook his head, getting water droplets on Sophia.

"No." He said.

"You said that when they captured you that they dragged you into a room and that there was a body in it." Stiles told him.

"What body?" Isaac asked, looking at Deaton.

"Erica." He said and Sophia leaned heavier into the cold, wet beta. She and the blonde she-wolf had never gotten close after Erica received the bite but she was still her friend before all of that. "You said it was Erica."

XXX

"She's not dead." Derek denied as he paced.

"Derek, he said, 'There's a dead body. It's Erica.' Doesn't exactly leave us much room for interpretation." Stiles said back to the Alpha.

"Then who was in the vault with Boyd?" He asked and Sophia shrugged.

"Obviously someone else." The she-wolf said.

"Maybe it as the girl on the motorcycle. The one who saved you?" Scott asked Isaac.

"No, she wasn't like us." Isaac said, shaking his head. "And whoever was in the vault with Boyd was."

"What if that's how Erica died?" Stiles asked and Sophia looked over at him. "They pit them against each other during the full moons and see which one survives. It's like werewolf thunderdome."

"Then we get them out tonight." Derek said.

"Be smart about this Derek." Deaton said. "You can't just go storming in."

"If Isaac got in, then so can we." Derek answered.

"But he didn't get in through a vault door." Sophia said and Deaton nodded his head.

"We need a plan." Scott said.

"How are we going to make a plan to break into a bank vault in less than 24 hours?" Derek asked Scott and Sophia.

"Uh, I think someone else already did." Stiles said, gaining their attention. "'Beacon Hills First National closes its doors three months after vault robbery.' Doesn't say here how it was robbed, but it probably won't take long to find out."

"How long?" Derek asked the boy.

"It's the Internet, Derek." Stiles said before scoffing. The Alpha raised his eyebrows at him. "Okay, minutes."

XXX

Sophia, Scott, and Stiles went back to Stiles' house to figure out the bank vault problem and somewhere down the line, they all fell asleep, Stiles was on the floor, Scott in his computer chair, and Sophia on his bed. Someone yelled and it caused all three of them to jump awake. "I got to get to work. You three need to get to school." The Sheriff said.

"Dad!" Stiles called after him. "Heather?" He asked.

"Nothing yet." He said before turning to walk back down the stairs.

"Ten hours and nothing." Stiles said, standing up.

"We're gonna find something." Scott said, hoping he sounded in encouraging.

"Finding something doesn't make Erica any less dead or Boyd any less about-to-be-dead." Stiles said, picking up the papers around the room.

"We still have some time." Scott said over Sophia groaning while she stretched.

"Is this whole 'remain optimistic in the face of complete and utter disaster' thing a part of the 'be a better Scott McCall' program?" Stiles asked.

"Not if it doesn't work." Scott said. Stiles sighs.

"No, it works." Stiles dropped all of the papers but one, handing it to Scott as he ran after his dad.

XXX

"Okay, you see this? This is how they got in. It's a rooftop air conditioning vent." Stiles said, spreading out the blueprints for the bank. "Leads down inside into the wall of the vault, which is here. One of the robbers was lowered into this shaft. Now, that space is so small it took him 12 hours to drill into that wall, which is stone, by the way. Then throughout the rest of the night, they siphoned the cash up to the guys back on the roof through that one little shaft in the wall. Boom." Stiles explained and Sophia had to admit. It was a pretty impressive plan.

"Can we fit in there?" Scott asked.

"Yes, we can but very, very barely. Sophia would have more luck than we would." The redhead looked up from the blueprints and nodded. "They also patched the wall, obviously, so we're gonna need a drill of some kind."

"Forget the drill." Derek said and Stiles stopped talking to turn to the Alpha.

"Sorry?" He asked.

"If I go in first how much space do I have?" Derek asked and Sophia looked him over.

"Not much." He rolled his eyes at her before turning to Stiles.

"What do you think you're gonna do, Derek? You gonna punch through the wall?" Stiles asked as he and the Alpha turned to each other. Derek crossed his arms and sighed.

"Yes, Stiles, I'm gonna punch through the wall."

"Okay, big guy. Let's see it. Let's see that fist. Big, old fist. Make it, come on. Get it out there. Don't be scared." Derek made a fist and held it up. Sophia shook her head, rubbing her forehead before continuing to watch the slowly unfolding train wreck that is Stiles. "Big, bad wolf. Yeah, look at that." Sophia glanced at Peter, who was watching quietly from the stairs. "Okay, you see this? That's maybe three inches of room." Stiles said, holding Derek's wrist with his other hand acting as the wall. "Three inches of room to father enough force to punch through solid…" Derek punched Stiles hand without moving it back. It knocked the boy's hand to the table. "Aah!" Stiles cradled his hand to his chest. Sophia covered her mouth as not to laugh at her best friend. "He could do it."

"I'll get through the wall." He said and Sophia raised an eyebrow before pursing her lips not to laugh at the sad whimper that came from Stiles. "Who's following me down?" He glanced at Peter.

"Don't' look at me." The older wolf said. "I'm not up to fighting speed yet, and honestly, with Isaac out of commission, you're not looking at very good odds for yourself."

"So I'm supposed to just let them die?" The Alpha asked.

"One of them is already dead." Peter said.

"We don't know that." Derek repeated his earlier statement.

"Do I have to remind you what we're up against here?" Peter asked. Sophia watched as Stiles came back over. "A pack of Alphas. All of them killers. And if that's not enough to scare you testicles back into your stomach, try to remember that two of them combine bodies to form one giant Alpha." Sophia scoffed.

"Thanks for that visual Uncle Peter." She said, pushing her hair back over her shoulder.

"Which one?" Stiles asked as he rubbed his hand.

"The testicle one. Which we should all remember I'm severely lacking in." She said and there was a moment of silence. She smiled before looking back down at the blueprints.

"Anyway, I'm sure Erica and Boyd were sweet kids. They're gonna be missed." Peter finished.

"Can someone kill him again, please?" Stiles asked and Sophia nodded. Peter turned back to them and stared at Stiles for a moment.

"Derek, seriously, not worth the risk." The former Alpha said. Sophia sighed and ran her fingers through her hair.

"If you do down Derek, I'm going with you." She said and the Alpha was about to open his mouth and argue but Sophia shook her head. "Trust me on this one. You want me there." He nodded his head before turning to look at Scott and Stiles.

"What about you?" He asked.

"Yeah, if you want me to come…" Stiles answered.

"Not you." Derek said, closing his eyes.

"Scott." Stiles said, motioning over to the Beta.

"I don't know about Erica. But if Boyd's still alive, we have to do something." He looked back at Peter, who crossed his arms over his chest and sighed. "We have to try."

"But?" Derek asked.

"Who's the other girl? The one locked in there with Boyd?" Scott asked.

XXX

Derek jumped up to the fire escape and Sophia bit her lip. Damn Derek! Everything she thought she was over the man he did something like that. With a sigh, she followed him. "Sophia!" Scott called after her.

"He needs somebody." She said to him before follow Derek to the roof. They'd easily found the shaft that Stiles had shown them on the blueprints. Derek went down first, showing the other two just how tight it was. Once they were down all the way, Derek literally punched through the wall. What was Derek's attractive level at before? Cause it was probably immeasurable at this moment.

"Boyd…" Derek calls one they were in the vault. Boyd stepped out of the shadows, growling. "It's me. It's Derek." The Alpha said. Sophia turned to Scott when she heard his phone buzzing.

"Stiles, now is not the best time." The beta said and Sophia trained her ears to what the other boy was saying.

'Scott! Scott! No, listen to me, okay?' Stiles yelled which caused Boyd to switch is attention to Scott. 'Look, you gotta get out of there. Look the walls of the vault are made of a mineral called hecatolite. It scatters moonlight.'

"And what does that mean?" Scott asked.

"We're here to get you out, okay?" Derek said to Boyd.

'Look, it keeps the moonlight out, okay? They haven't felt a full moon in months.' Stiles said.

'Think of it like the gladiators in the Roman Coliseum. They used to starve the lions for three days, making them more vicious, more out of control. Deucalion has kept them from shifting for three full moons, diminishing their tolerance to it.' Peter said, taking over for Stiles.

'Scott, they're gonna be stronger…' Stiles started again.

'More savage, more bloodthirsty. Scott, they're the lions. They're the starved lions and you, Derek, and Sophia just stepped into the colosseum.' Peter finished. Scott looked at Sophia and she reached out, grabbing Derek's arm.

"We got a problem. A really big problem." She said, once the Alpha turned to her. The other werewolf stepped out growling, causing the three of them to turn. Derek froze when he saw her.

"Cora?" He asked.

"Who?" Scott asked and Sophia blinked twice, making sure she wasn't seeing things. She hadn't seen Cora since she was a baby… since the fire…

"Cora?" Derek questioned again, sounding like he was going to cry.

"Derek, get out. Get out now." She said. The vault went silent except for Stiles' yelling over the phone. The door opened and a woman was standing there. She knelt down and poured something on the ground. Immediately Sophia noticed it was Mountain Ash.

"No. No! Wait!" Scott yelled to her right before Boyd and Cora let themselves shift into beta form, feeling the effects of their first full moon in months. Immediately, both betas came at the three other werewolves. Scott, Derek, and Sophia struggled to keep the other two werewolves under control. The three of them ended up back to back against a wall.

"You know her?" Scott asked the Alpha at his side.

"She's my sister, my younger sister." Derek answered, looking between the young beta and his sister.

"What the hell is she doing here?" Scott asked again.

"Like I have a clue. I thought she was dead!" Derek said back to him.

"Look out!" Someone yelled and Sophia and Derek dodged to the side just in time to avoid Boyd. He threw Scott around. Sophia turned when she heard something behind her, only to be scratched across the face by Cora. The redheaded beta growled as she avoided Cora's attacks. Derek came over as well but it didn't bother Cora, she just divided her attacks between the two of them. Derek held Cora off when some movement caught Sophia's attention. Allison was sitting on the base of the safe door, getting ready to break the Mountain Ash circle.

"Don't break the seal!" Sophia called to her, causing the brunette to look up at her and then Scott.

"Boyd!" She called before breaking the circle. Immediately, Boyd and Cora took off out of the vault and into the bank. Sophia was tackled down by Cora on her way out. The girl rolled over onto her stomach, her eyes flashing before she took off after them. She didn't know if Scott or Derek were going to try and keep up with them but she knew she had to do something. She wasn't going to let them run rampant all over town… she couldn't.
