I sat on Derek's bed looking at my phone. Heather hadn't text me all night which was strange considering we were texting during her birthday party. Was she mad at me? She said she understood why I didn't show up. "I'm starting to not like this idea." Isaac said pacing. "It sounds kind of dangerous." He paused. "You know I definitely don't like this and I definitely don't like him."

"You'll be fine." Derek was sitting on a stool near a table. I begged him to let me decorate, but he refused so we were stuck with this dark dainty loft, but dark and dainty was so Derek and I accepted his wishes.

"Does it have to be him?"

"He knows how to do it, I don't. It would be more dangerous if I tried to do it myself."

"Scott doesn't trust him." Isaac said. "And personally I trust Scott."

I rolled my eyes. "Get over your man crush Lahey."

Derek looked at me and winked with a smiled. I love him. "Get over yourself Stilinski."

I stuck my tongue out at him. "What are you two? Children?"

We were both quiet. "I still don't like him." Isaac complained.

"Nobody likes him." Derek and I said at the same time.

The door opened and Peter walked in. "Kids, 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 you're feeling straight to my face."

Derek looked at him, his face with no emotion. "We don't like you," He stood up and I sat up on the bed. "Now shut up and help us."

He paused for a moment. "Fair enough." Derek and I sat on his futon as Isaac sat on a chair in front of Peter. "Relax, I'll get more out of you if you're cold."

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

"It's an ancient ritual used mostly by alphas, but it requires quite a bit of practice." He ran his fingers down Isaac's neck. "One wrong slip and I could paralyze you, or kill you."

Derek and I both looked at each other and then at Peter. Maybe this wasn't the best idea. "You've had a lot of practice though, right?" Isaac asked hopeful.

"Well, I've never paralyzed anyone."

Derek and I looked at Peter. He had hardly any experience. "Does that mean you-" He stuck his nails into Isaac's neck. We both watched as they twitched and their bodies jerked. Derek stood up and I held onto his arm. Peter pulled away and I went to Isaac who almost doubled over. I set him up straight in his chair and smiled at him. "What did you see?" Derek asked.

"Well," Peter began. "It was confusing." He looked at his hands. "Um, just vague shapes."

"But you saw something?" Derek asked.

"Isaac found them"

"Erica and Boyd?" I asked.

"I bearly saw them." Peter stuttered. "Just glimpses."

"But you did see them?" Derek pressed on.

"And worse."

"Deucalion." Derek finished.

"He said something about time running out."

Isaac gulped. "What does that mean?" He whispered.

"He's going to kill them." Derek answered.

"What?!" I exclaimed.

"No, no, no." Peter said. "He didn't say that, he did say that by the full moon they would both be dead."

"The next full moon?" I asked.

Peter turned to me. "Tomorrow night."

Not long after Scott called me. "Hey."

"Are you with Derek?"

Derek heard and looked up at me. "Uh, yeah. I was just about to go to school. Why? What's up?"

"Can you bring Derek?"

"Can I ask why?"

"Just get over here."

Derek drove me to school and I snuck him into the back of the portable Scott told me to meet him in. When we got into the classroom Scott, Stiles, Lydia and Allison were waiting for us. That's why Scott didn't tell me because he knew I would say no if it had anything to do with Allison. Lydia and Allison began to explain how a girl grabbed their hands and left a bruise on them that they thought made a pattern. "I don't see anything." Derek said.

"Look again." Scott said.

"How is a bruise," I began. "Going to tell us where Boyd and Erica are?"

"It's the same, on both sides." Scott said. "Exactly the same."

"It's nothing." Allison and Derek were having a stare down.

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

Derek broke his stare from Allison to look at Scott. "These two?" He pointed at Lydia. "This one, who used me to resurrect my psychotic uncle, thank you." He turned to Allison. "And this one who shot about thirty arrows into me and my pack."

"Okay," Stiles said. "No one died. There may have been a little mangling, but no death. That's what I call an important distinction."

"Stiles," I began. "Shut the hell up." He made a face at me and I made one back.

"My mother died." Allison said. Allison still didn't know what really happened the night of the rave. That her mother tried to murder Scott, Derek and me.

"Your family's honor code killed your mother, not me."

"That girl was looking for Scott, I'm here for him, not you." She thought she looked so threatening, but I knew Derek was unimpressed, so was I.

"You want to help? Find something real."

I saw Allison's face drop and I whispered to Derek that I was going to walk him out. "Wait," Scott said. Derek and I both turned around. "Give her a chance." He said it to me more than anyone. "She's on our side now."

"Then maybe you should tell her what her mother was actually trying to do that night." I said right before the two of us walked out of the room. It was starting to sprinkle outside so I pulled my red cardigan closer to me. "I'm sorry I wasted your time." Derek shrugged and I turned him to look at me. "What are we going to do about Erica and Boyd?"

Derek shook his head and looked down. "I don't know."

"Hey." I picked his head up and smiled. "None of this is your fault."

He smiled at me and wrapped his hands around my waist. "You drive me crazy, you know that?"

"Good or bad?" I asked wrapping my arms around his neck.

He chuckled. "Both." We both kissed as the sprinkles fell down on our cheeks. "I love you." He said when he pulled away. He kissed me again. "And all of this is going to work out, I promise."

"And I promise you that everything is going to work out." He kissed me one last time and held onto my hand as he walked away.

After he left Stiles and Scott came out of the cubical and we all walked to our next class together. "What would a pack of alphas want with Erica and Boyd?" Stiles asked.

"I'm not sure it's them they want." I said.

"What like Derek? Like they're recruiting?" I turned to look at Scott to see if he had any ideas, but he was looking over at the twin brothers who had just moved here. "Hey, Scott." He turned to us confused. "You coming?" He nodded, but he had a weird look on his face as he walked ahead of us. Stiles and I looked at each other confused and then continued walking after him.

We got into Introduction to Business, the class we had with Coach. I had to admit, I missed him a little bit over the summer. He slammed the book down and we all jumped. "The stock market is based on two principals. What are they?" Scott was the first to raise his hand and I followed right after him. "Yes McCall, you can go to the bathroom."

Everyone laughed and then Coach turned to me. "No Coach," Scott said. I turned to him and put my hand down. "I know the answer." There was no way.

Coach laughed and Scott sat there with a straight face. "Oh," Coach said as he stopped laughing. "You're serious."

"Yeah, it's risk and reward."

"Wow," Coach moved up to him. "Who are you and what have you done with Scott McCall? Don't answer that, I like you better." He hit his desk excitedly. "I like you better."

I was impressed. I gave Scott a smile and he looked bashful. "Does anybody have a quarter?" Stiles began to reach into his pocket and a condom fell out, not just any condom, an XXL condom. My mouth dropped. Did my twin brother loose his v card and not tell me about it? Coach picked it up and gave it to him. "I think you dropped this and congratulations."

I read his mind. He was going to sleep with Heather last night. Our childhood best friend Heather. We all took bubble baths together and he was going to sleep with her. I smacked him in the back of the head and he turned to me. "Bree, if you don't get out of my head I swear to God-"

"Hey! Stilinski twins!" We both looked up. "Shut up!" I sat back in my seat and Coach nodded. "That's better." He raised the quarter in the air. "You get the quarter in the cup you get the reward." He got down on the ground. "Watch Coach." He skipped the coin and it landed in the cup perfectly. We all applauded. "Danny!" He threw the quarter to him. "Risk or reward?"

"What's the reward?"

"You don't have to take the pop quiz tomorrow."

"Coach," Danny said. "It's not a pop quiz if you tell us about it."

Coach took the quarter from him. "You know, I really expect more from you at this point." He moved to Scott. "Risk or reward?" Scott thought about it for a moment and then put it down. "No play." Coach said. "Okay, who else wants it?" Stiles hit his books and then stood up. "There we go, there's a gambling man."

Stiles danced to the front of the classroom and got ready to shoot the coin in the mug when the door opened and Dad walked in. "Stiles." Coach said.

"Yeah Coach?" He didn't notice who was standing in the door.

"Stiles." Dad said. I looked at Stiles and then at Dad. He gave me a small smile as he walked out with Stiles.

I looked at Scott and he nodded. He was going to listen in on their conversation. Heather was missing and Stiles was the last to see her, right before he was going to have sex with her (so weird). "So you think they took Heather to turn her?" Scott asked as we walked down the hall.

"Derek said it's easier to turn teenagers." Stiles said.

"But what would an alpha pack want with a beta?" Scott asked.

"I don't care." I said. "Our moms were best friends when she was still alive. We did everything together when we were three. We have to find her."

"Then we need Isaac to remember." Scott said.

"How?" Stiles asked. "Derek couldn't do it. Do you know any other werewolves who could do it?"

I stopped walking and they both stopped to look at me. "Maybe not werewolves." I said. "Maybe a witch and someone who knows a lot about werewolves."

I pulled out the grimoire from my bag and began to go through it. "You're just going to pull that out in the middle of the hallway?" Stiles asked.

"It's a book." I said obviously as I moved to the side of the hallway.

"Yeah, a creepy book with spells and hexes."

I rolled my eyes at him. "Here look." I pointed at it and they just stood there.

"B," Scott began. I turned to look at him. "That's in Latin."

I closed the book and put it back in my bag. "You two seriously need to learn Latin."

After school we all headed to Deaton's office with Isaac and Derek. "Let me see the book." Deaton said as I walked in. I had text him all the info. He skimmed it. "You're right." I smiled. "This can work."

"What is it?" Isaac asked.

I looked at Isaac and then at Deaton. "Where's your ice?"

"The back."

I turned to Derek. "Help me?"

He followed me and I explained what we had to do. We all began to put bags and bags of ice into the tub. "If we can slow your heart rate down enough," I heard Deaton explain to Isaac. "Then we can put you in a trance like state."

"Like being hypnotized?"

"Exactly," They both moved closer to the tub. "You'll be half transformed. It'll let us get into your subconscious mind."

"How slow does his heart rate need to be?" Scott asked.

"Nearly dead."

Derek looked at Deaton and then at me. "Do you have any other ideas?" I asked him. I turned to Isaac. "But if you don't want to do this just tell us and we'll figure out another way." Derek and Scott both nodded.

Isaac took off his shirt and got into the water as fast as he could. Derek and Scott both pushed him down and I stood by Stiles. Isaac tried to push his way out and they held him down even tighter, but it wasn't working. I reluctantly held him down with my powers until he stopped moving. He floated to the top and looked peaceful. "Now remember," Deaton said. "Only I talk to him, too many voices can confuse him and draw him out."

When Deaton began to talk about Erica and Boyd he began to twitch a little. "I don't want to do that." The lights began to flicker and we had to hold him down some more. He calmed down and we all let go. "It's stone." Isaac said. "Like marble."

"Perfect," Deaton said. "Can you give me any other descriptions?"

"It's dusty and empty." He grabbed Scott's arm. "Someone's here."

"Isaac, relax."

"They see me! They see me!" He began to move even more and scream, but Deaton calmed him back down.

"Tell us what you see." Deaton said.

"I hear him, he's talking about the full moon, about being out of control when the moon rises."

"Is he talking to Erica?"

"I think so. I can't see her. I can't see anyone." He paused. "They're worried. They're worried about what they're going to do on the full moon. They're worried they are going to hurt each other."

Derek shook his head. "If they're locking them in together on the full moon they are going to tear each other apart."

We all shared worried looks. "Isaac, we need to find them right now. Can you see them?"

Isaac sat up quickly and the lights began to flicker even more. "They see me!"

"It'll be okay." Deaton said. "Just tell-"

"They see me! They've found me! They're going to kill me!"

"This isn't working." Derek said. "Isaac where are you?"

"I can't see! It's too dark!"

"Derek!" I yelled. "What the hell are you doing?!"

Everyone was yelling at once. "He can go into shock!" Deaton yelled.

"Derek let him go!" Scott yelled.

"Where are you?! What do you see?!"

"They dragged me into a room! There's a body! Erica's body!" We all looked at each other shocked. "A vault!" He sat up quickly. "A bank vault!" He paused. "I saw it! I saw the name. We helped him out and gave him a blanket. "It's Beacon Hills National Bank. They're keeping them locked inside the vault."

"She's not dead!" Derek said after Isaac put his shirt back on. "Then who is in the vault with Boyd?"

"Someone else." I said with a shrug."

"It could be the girl on the bike." Scott said.

"She wasn't like us." Isaac said. "And whoever is in the vault was a werewolf."

"Maybe that's how Erica died." Stiles said. "They pit them against each other and see which one survives. It's like werewolf thunder dome."

"Then we get them out tonight."

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

"Isaac got in and so can we." I began to search for Beacon Hills National Bank on my phone.

"But he didn't get through a vault door."

"We need a plan." Scott said.

"You want to come up with a plan to break into a bank vault in less than twenty four hours?" Derek asked.

"Someone already did." I said. They all turned to me and I read the article off of my phone about how someone broke into the vault.

"It doesn't say how," Stiles said looking over me. "But it shouldn't take long to find out."

"How long?" Derek asked.

Stiles chuckled. "It's the internet Derek, minutes."

It didn't take minutes. It literally took all night, but we found out from Dad who made the arrest. That night we all met at Derek's loft with blue prints of the bank and a plan. "Okay, you see this?" Stiles said pointing at the top of the map. "This is how they got in. It's a rooftop air conditioning vent. It leads down inside to the wall of the vault which is here." He circled a place on the map. "One of the robbers was lowered down into this shaft. Now, this place is so small that it took them about twelve 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." He hit the map with his fist. "Boom!"

"Can we fit in there?" Scott asked.

"We can." Stiles said. "But bearly so obviously we're going to need a drill of some kind."

"Forget the drill." Derek said. "If I go in first how much space do I have?"

I turned to him with my jaw dropped. He had a death wish. "What do you think you're gonna do Derek? You're going to punch through the wall?" I rolled my eyes. Here we go again, another Derek and Stiles argument.

"Yes Stiles," Derek said with a sarcastic smile. "I'm going to punch through the wall."

"Okay big guy, let's see that fist." Derek's smile was gone and he showed him his fist. "Big bad wolf, look at that." He put his hand out in front of Derek's. This was going to end badly. "That is maybe three inches of room to gather enough room to punch through solid-" His sentence was cut short by Derek punching Stiles' hand. My mouth dropped as Stiles walked away from the pain. "He can do it."

"I can get through the wall." Stiles screamed a little. "Who's going to follow me?"

"Me obviously." I said. "I have a magic light that comes out of my hands and if I can survive a fight with my killer ex boyfriend as the Kanima I think I can take on a few werewolves."

Derek shook his head. "You're not coming."

"Why not?"

"Did you not forget what happens if a werewolf bites you? Bree, you're dead." I crossed my arms and he got closer to my face. "You're not coming."

I shook my head at him and he turned to Peter. "Don't look at me; I'm not up to fighting speed yet. And honestly, with Isaac out of commission you're not looking for very good odds yourself."

"So I'm supposed to just let them die?"

"One of them is already dead."

"We don't know that." I put my hand on Derek's shoulder. I could feel it. Erica was dead, but Derek still had hope.

"Do I have to remind you what we're up against here?" Peter asked. "A pack of alphas, all of them." Stiles came up still holding his hand. "Killers, and if that's not enough to scare your testicles back into your stomach try to remember that two of them combine bodies to form one giant alpha. Sure, Erica and Boyd are sweet kids and are going to be missed."

I gave Peter a look. "Can someone kill him again please?" Stiles asked.

"What about you?" Derek asked.

"Yeah," Stiles answered. "If you want me to come."

"Not you!"

He looked at Scott. "I don't know about Erica," He answered. "But if Boyd is still alive then we have to do something. We have to try."

"But?" Derek asked.

"Who's the other girl?" Scott asked confused.

That was a question none of us knew the answer to. Derek and Scott were about to leave when I stopped them. "Derek," He turned to me sympathetically. "Be careful. Boyd is going to be crazy and so it that girl. You can't get hurt." I shook my head. "I don't know what I'd do if you got hurt." He kissed me and when he pulled away he looked into my eyes like he was looking into my soul. "I love you." I breathed.

"I love you."

They left and we waited for about an hour. "I can't stand this." Stiles said looking out the window. "I can't just wait around like this."

"How do you think I feel?" I said bending down to pick up some trash from the floor. I had went to cleaning (one of my stages of being nervous).

"It's nerve racking." Stiles said. "My nerves are racked!"

"I could beat you unconscious." Peter said. "And wake you when it's over."

I sat across from Peter. "Do you think Erica is really dead?" Stiles asked.

"You think I really care?" I pushed Peter's feet off the table and he gave me an annoyed look.

"I don't understand it." Stiles said. "Why a bank? Why not an underground lair or something?" He thought for a moment. "Wait a sec, wait a sec. Maybe they live there. Maybe the bank vault reminds them of their little wolf dens!"

"Wolf dens?" I asked.

"Yeah," Stiles turned around to Peter. "Where do you live?"

"An underground network of caves deep in the woods."

"Wow! Really?"

"No you idiot." I smiled. "I have an apartment downtown."

Stiles looked a little disappointed. "Fine! That just proves that there is something going on with the bank and why wait around for the full moon? Why not just kill them whenever they want to?"

"Maybe they think it's poetic." Peter said.

"They've had three full moons to be poetic."

"And you've had one full hour to be so annoying."

"Wait," I said. "The walls, what are they made of?" Peter straightened up seeing where I was going with this. We both got up and moved to the maps and blue prints of the vault.

"Where would it say the materials?" Peter asked. "The type of stone."

"Here," Stiles said giving us a packet of papers. "They've got to be in there." We flipped through them quickly. "There!" Stiles said pointing.

"Acidulate." Peter said looking at me with a panicked look. "Get him on the phone." I pulled out my phone and called Derek's number.

"What the hell is going on?" Stiles asked.

"Erica and Boyd aren't going to kill each other." I said. "They're going to kill Derek and Scott." Derek ignored my call. "He's not picking up!" I was shaking.

Stiles pulled out his phone, called Scott and put him on speaker. "Now is not the best time."

"Scott, listen to me!" Stiles yelled. "You have to get out of there. The walls of the vault are made of acidulate. It scatters the moonlight."

"What does that mean?"

"It keeps the moonlight out!" I yelled. "They haven't seen the moon in months."

"Think of it like the gladiators in the Roman coliseum." Peter said. "They used to starve them for days to make it more vicious and out of control. Deucalion has kept them from shifting for three full moons diminishing their tolerance to it."

"Scott," I said. "They're going to be stronger."

"More bloodthirsty," Peter continued. "Scott, they're the lions and you and Derek just stepped into the coliseum."

There was nothing, but muffled commotion. "Scott?" Stiles asked.

"Derek?" I asked. There were growls and screaming then the line went dead. "Derek!"
