Stiles POV: After school they went to the animal clinic where they explained everything to Deaton. He told them to filled a metal bin with tons of ice and water and call Isaac.

"Obviously it's not going to be particularly… comfortable. But if we can slow your heart rate down enough you'll slip into a trance-like state" Deaton explained.

"Like being hypnotized" Isaac said.

"Exactly. You'll be half transformed it'll let us access your subconscious mind."

Stiles couldn't look at Isaac without half wanting to kill him.

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

"Very slow" Deaton said.

"Okay well how slow is very slow?" Derek asked.

"Nearly dead."

"It's safe though right?" Isaac asked as he knelt down next to the bin of water.

"Do you want me to answer honestly?"

"No no not really."

"Look if it feels to risky you don't have to do this" Derek said.

Isaac just looked at the water and took off his shirt and shoes. Then he slowly got into the bin and sat down breathing hard. Scott and Derek put their hands on his shoulders and pushed him down into the water. Isaac struggled his eyes changed his fangs came out he roared when he came back to the surface.

"Get him back under" Deaton told them.

"Hold him."

"We're trying" Derek growled.

Soon Isaac stopped fighting and they let him go so he slowly floated to the surface.

"Now remember only I talk to him. Too many voices will confused him and draw him out. Isaac? Can you hear me?" Deaton said softly.

"Yes I can hear you."

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

"Yes."

"I want to ask you about the night you found Erica and Boyd. I want you to remember it for me in as vivid detail as possible like you're actually there again."

"I… I don't wanna do that. I don't… I don't wanna do that. I don't wanna do that" Isaac said as he started to struggle in fear and the lights flickered as a storm started outside.

"Isaac it's all right just relax. They're just memories you can't be hurt by a memory."

"I don't wanna do that."

"Relax. Relax. Good. 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?" Deaton continued as Isaac relaxed again.

"It's not… it's not a house. It's stone I think marble."

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

"It's dusty so empty. Like an abandoned building?"

Then Isaac struggled again.

"Isaac? Isaac?"

"Someone's here. Someone's here."

"Isaac relax."

"No no no they see me they see me!" the lights flickered again.

"Just memories. You won't be hurt by your memories. Just relax. Relax. Good. Now tell us what you see. Tell us everything."

Isaac opened his eyes but he didn't look at anyone.

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

"It he talked to Erica?"

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

"Can you hear anything else?"

"They're worried. They're worried what they'll do during the fill moon. They're… worried that they're gonna hurt each other."

"If they're locked in together on the full moon they're gonna tear each other apart" Derek said softly.

"Isaac we need to find them right now. Can you see them?" Deaton asked.

"No."

"Do you know what kind of room it is? Is there any kind of a marker? A number on a door? A sign?"

Then Isaac sat up the lights flickered again as the storm now raged outside.

"They're here" Isaac said softly.

Then he began to whimper and tried to get away.

"They… they…"

"It's all right."

"No."

"Just tell us…"

"They see me they found me they're here!"

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

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

"Just tell me where you are" Derek growled.

"You're confusing him" Deaton said.

"I can't see!"

"Isaac where are you?! Just tell me where you are" Derek grabbed Isaac.

"His heart rate… he could go into shock" Deaton explained.

"Derek let him go!" Scott yelled.

"Isaac where are you? What did you see?"

"A vault! It's a bank vault! I saw it! I saw the name. It's uh… B… Beacon Hills first national back. It's um… it's an abandoned bank and they're keeping them locked inside…inside the vault. What?" Isaac said as he got out of the water the power was off and Deaton wrapped a towel around him.

"You don't remember what you said right before you came out of it do you?" Stiles asked.

"No."

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

"What body?"

"Erica. You said it was Erica."

"She's not dead" Derek said 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.

"Then who's in the vault with Boyd?" Derek fired back.

"Someone else obviously" Stiles replied.

"And maybe it was the girl on the motorcycle okay the one who saved you?" Scott said.

"Nah she wasn't like us. And whoever was in the vault with Boyd was" Isaac said.

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

"Then we get them out tonight" Derek said.

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

"If Isaac got in then so can we" Derek argued.

"But he didn't get through a vault door did he?" Deaton asked.

"We need a plan" Scott said.

"How are we gonna come up with a plan to break into a bank vault in less than 24 hours?" Derek asked angrily.

"Uh I think someone already did. '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" Stiles said using his phone.

"How long?" Derek asked.

"It's the internet Derek. Okay? Minutes" Stiles said.

Stiles and Scott stayed up looking at Stiles' house until they fell asleep where they were. Stiles was half on his bed half on the floor when his dad woke them up plus he had a piece of paper stuck to his face.

"Dad. Heather?" Stiles asked looking up at his dad.

"No nothing yet" his dad said then he left the room.

"Ten hours and nothing" Stiles said as he started to pick up paper on the floor. \

"We're gonna find something" Scott promised.

"Finding something doesn't make Erica any less dead or Boyd any less about-to-be-dead."

"Well we still have time."

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

"Uh not if it doesn't work."

"No it works. Oh dad! Dad? Dad!" Stiles shoved a piece of paper showing his dad arresting the bank robbers at Scott and ran out to catch his dad.

"All right so we meet at Derek's at 5 to go over the plan and then we don't get started until dark" Scott said once they were at school.

"Kay what do we do till then?" Stiles asked.

"What right now? We've got English."

Selene POV: Selene was at Derek's when he and Isaac got back from the animal clinic and they told her everything.

"You okay?" she said Isaac.

"A little cold little shaken but yeah I'm okay" he told her.

"I felt it. Your fear and your rage both so intense. If you hadn't warned me of what they were going to do to Isaac you may have had a very pissed off wolf bursting into the clinic" she said looking at Isaac then Derek.

"I didn't know it would be that... intense" Isaac said softly.

"Selene tonight if they come up with a plan I'd like you to wait here or at your place" Derek asked her.

She almost argued with him but just the thought of seeing Stiles made her want to cry and made her eyes teeth and nails change. So she nodded knowing she wouldn't be much help with two out of control wolves when she didn't have much control herself right now.

"But if you need me promise you'll call" she said and Derek nodded.

"How many miles?" Derek asked.

"What?" she asked as she got a grip on her control.

"How many miles have you run to steam off your emotions?"

She looked away. "I've lost count. I feel less in control now than I have in centuries."

"I think him not returning the mate bonding is…I think it's turning you feral or worse killing you" Derek said.

She looked back at him her eyes again going Alpha red.

"That depends on your definition of the word 'worse'."

Then she went home to try and sleep.

Stiles POV: After school at Derek's loft Stiles laid out the blue prints for the bank.

"Okay you see this? This is how they got in. it's a rooftop air conditioning vent. Leads down inside into the wall of the vault which is here. Okay? One of the robbers was lowered into this shaft. Now that space is so small it took him about 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" Stiles explained pointing things out.

"Can we fit in there?" Scott asked.

"Yes we can but very very barely. And they also patched the wall obviously so we're gonna need a drill of some kind. I'm thinking maybe a diamond bit…" Stiles said.

"Forget the drill" Derek said.

"Sorry?" Stiles asked confused.

"If I go in first how much space do I have?"

"What do you…what do you think you're gonna do Derek? You gonna punch through the wall?" Stiles said sarcastically.

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

"Okay 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. Big bad wolf. Yeah look at that. Okay see this? That's maybe three inches of room to gather enough force to punch through solid con…" Stiles held up his hand to show Derek three inches of space but Derek punched Stiles' hand.

Stiles cried out and cradled his hand as he walked away.

"He could do it" Stiles yelled back.

"I'll go through the wall. Who's following me down?"

"Don't look at me. I'm not up to fighting speed yet and honestly with Isaac out of commission and Selene going feral which I look forward to with dread and interest by the way you're not looking at very good odds for yourself" Peter said.

"Whoa wait what about Selene?" Stiles asked worried.

"So I'm supposed to just let them die?" Derek said ignoring Stiles.

"One of them is already dead."

"We don't know that."

"Do I have to remind you what we're up against here? A pack of Alphas. All of them 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. I'm sure Erica and Boyd were sweet kids. They're gonna be missed."

"Could someone kill him again please?" Stiles asked forgetting for now his question about Selene.

Peter glared at him. "Derek seriously? Not worth the risk."

"What about you?" Derek asked.

"Yeah if you want me to come…"

"Not you" Derek said to Stiles.

"Got it."

"I don't know about Erica. But if Boyd's still alive we have to do something. We have to try" Scott said.

"But?" Derek asked.

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

In the end Scott ended up going with Derek leaving Peter and Stiles at the loft.

"I can't take waiting around like this you know? It's nerve racking my nerves are racked they're severely racked. Racked" Stiles babbled awhile later.

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

"You think Erica's really dead?" Stiles continued.

"You think I really care?"

"I just… I don't understand the bank though okay? Wha…like why wouldn't the chain them up in some underground lair or something? They're an Alpha pack right? So shouldn't they have a lair?"

"They're werewolves not Bond villains."

"Wait a sec wait a sec. Maybe the bank vault reminds them of their little wolf dens."

"Wolf dens?"

"Yeah wolf dens. Where do you live?"

"In an underground network of caves deep in the woods."

"Whoa really?"

"No you idiot I have and apartment downtown."

"Okay fine but still that just proves that there's something up with the bank. And why wait around for the full moon huh? Why not just kill them whenever they want to?"

"Maybe they think it's poetic."

"They've had already had 3 full moons to be poetic" Stiles said.

"And here you've only had one full hour to be so annoying…"

"No go ahead finish what you were saying. I'm an… I'm annoying. What were you gonna say there?"

"What are the walls made of?"

"What? Uh… I don't know like wood and brick or…"

"No the vault the vault the walls what are they made out of? Where would it say that? Doesn't say anything. Where… where would it say the materials the type of stone?" Peter said looking at the blue prints.

"Oh… oh hang on. Yeah here hang on here. It's gotta be in there" Stiles said as he pulled a stake of bound paper from his back pack.

"There that's it" Stiles said pointing at the paper.

"Hecatolite."

"Is that awful? That sounds awful."

"Get'em on the phone. Call them now!"

"Okay why?" Stiles said getting his phone out.

"Cause Boyd and that girl aren't gonna kill each other. They're gonna kill Derek and Scott."

"Stiles now is not the best time" Scott said answering his phone.

"Scott! Scott! No listen to me okay? Look you gotta get outta there. Look the walls of the vault are made with a mineral called hecatolite. It scatters moonlight."

"What does that mean?"

"Look it keep the moonlight out okay? They haven't felt the full moon in months."

"Okay think of it like the gladiators in the Roman Colosseum. 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 into the phone.

"Scott their gonna be stronger…"

"More savage more bloodthirsty Scott they're the lions and you and Derek just stepped into the Colosseum" Peter explained.

Then growls and roars came through the phone.

"Scott? Hey Scott! Scott!" Stiles yelled but the line was dead.
