"You have no fucking right to ask for help Derek. From any of us!" Isaac says, almost yelling.

Derek pauses for a moment, seeing the scared look on Stiles' face, he sighs while looking at his feet shamefully. "I know, but Isaac this is really important. Deucalion and his new pack of non-alphas are here. They've taken Cora and I can't do anything about it! I've already asked the twins to help and they said they would just to get revenge on Deucalion for abandoning them, but it's not enough."

"Why not? If his new pack isn't alphas then the three of you should be able to do whatever you're planning on your own." Scott says, cutting in before Isaac can jump off the couch and rip out Derek's throat, with his teeth.

"His new pack might not be Alphas Scott but it's not your average pack. I have no idea how he's done it in such a short amount of time but there's almost twenty of them, maybe more."

"Twenty werewolves?" Scott asks, shocked and also puzzled how that could be possible.

"Yeah. They came to my apartment about an hour ago and took Cora. Deucalion thinks she has 'potential', more than she's letting on, and I think he wants her to kill me. I'm sure he's going to lock her up or something, torture her again until she agrees to whatever he wants. Cora's smart but not smart enough to get herself out of there. Ethan and Aiden are tracking Deucalion at the moment and are going to call me when they find him. We were counting on the fact that you guys would help so we could come up with a plan and ambush them as soon as possible."

"Well I'm sorry that they took your sister but we can't help you. You're too much of a dick." Isaac says, not one ounce of sympathy in his voice.

"Speak for yourself Isaac, I'm going to help. Derek might be a dick, but we all know what it's like when your family or friends are in trouble. So whatever grudge you've got put it behind you, for now at least." Scott says, in true alpha-speech fashion. They all did have grudges against Derek, even Danny because of the fact that Derek doesn't seem to have any appreciation for human lives.

"Thank you Scott." Derek says, his head still hanging low as he tries to avoid looking at Stiles, who has surprisingly stopped cowering and is squinting at Derek, looking suspicious.

"How do we know you aren't screwing us over?" Stiles says in a low voice, startling Isaac.

"You're considering helping him? Stiles you really don't have to after what he did!" Isaac pipes up, his face a mix of confusion and disbelief .

"Isaac, I'm fine I promise." Stiles says looking into Isaac big, blue, pleading eyes reassuringly.

"I'm not screwing you over, okay. Look at the freaking hole they left in my side!" Derek states while gesturing to the slowly healing, gouged out part on the right side of his body.

It takes a few minutes of argument, and questioning looks between Isaac and Stiles before everyone agrees to help and after Lydia and Allison have patched up Derek they all wait for a call from the twins. It doesn't take long before they all hear Derek's 'bad to the bone' ringtone and moan while rolling their eyes at the irony of it. He picks up the phone and they all listen to multiple 'yep', 'mmhmm' and 'okay's' before he says "Alright, meet us all at Allison's as soon as you can." Followed by his explanation of what the twins found.

"There's a camp in the woods, they have a series of tents set up and the area around them is thick with traps. There are 22 of them including Deucalion, and Cora is in a cage made from logs in the centre of the camp. Her cage is surrounded by a circle of mountain ash meaning that Ms Morrell is still helping Deucalion." Aiden pauses, letting his brother continue the story while pointing to various points on the hand drawn map of the camp they are all huddled around in Mr Argent's office.

"We're gonna need a plan to get through their outer defences, and then we'll need something with enough force to get rid of most of the werewolves. There's no way we can take them all out even with the seven of us werewolves and Allison." Ethan says, his statement blunt and the twins' descriptions to the point.

"Seven?" Scott asks.

"Peter is on watch at the camp, just to make sure nothing big happens while we're planning." Derek replies.

"What about me, Danny and Lydia?!" Stiles asks, seeming so unfazed by being near Derek now, to the point where Isaac is wondering if anything happened at all.

"You want to put your life in danger? You all sound like you're talking about a bloody war!" Danny adds, sounding scared and a little baffled at how formal everything is.

"This is war." Derek says, without one inch of sarcasm. "And as for the three of you," He points to Stiles, Lydia and Danny. "Well one of you will need to break the ash circle, and if we're going to disarm their traps then you can help out with that too." Derek replies matter-of-factly.

They all start to organize a raid on the pack and after fifteen minutes they've come up with a decent plan. While everyone is making preparations and collecting things they'll need, Isaac grabs Stiles and pulls him into the spare bedroom shutting the door behind them. It's almost half past 12 and they are both looking weary from lack of sleep. Isaac drags Stiles over to the bed and they sit down next to each other holding hands.

"Are you sure you're okay with helping Derek?" Isaac asks, his face lined with concern.

"I'm sure. Isaac I'll be fine as long as I have you. I spent my whole life shutting things out and I've gotten pretty good at it, I know you have too, so can you just trust that I've got this under control and I'll come to you if it gets too much or if anything happens?" Stiles replies, meaning what he says about blocking things out, although he still wanted to throw up occasionally when he saw Derek. He couldn't really remember much of that night honestly, just enough to know what happened.

"I do trust you, and what you say, I just worry that this is something that's bigger than your ability to 'block things out'."

"I'm fine, I promise." Stiles says, before leaning over to kiss Isaac gently. "Actually I'm better than fine, I'm feeling good. I mean how could I not feel good with a boyfriend as gorgeous as you!" They both laugh and collapse back onto the bed kissing and giggling, until someone knocks on the door and clears their throat.

"Guys it's just Scott. Are you doing kinky things or can I come in?" Scott asks through the door.

"You can come in! Unlike some people we don't do 'kinky things' in other people houses." Stiles replies sarcastically. Scott opens the door cautiously and walks in.

"Ha, ha. Very funny Stiles, but… wait, when have I ever done that?"

"Try last week when you and Allison came over to get some of your things you left at my house. I left for literally like a minute, and came back to find you two half naked. On. My. Bed!"

"Oh, ok yeah. Anyway, we're all getting ready to leave, you guys coming?" Scott says, gesturing towards the door.

"Yep, we'll be there in a minute!" Stiles says, smiling and shooing Scott out the door.

"So you're sure you wanna do this?" Isaac asks again.

"Definitely sure!" Stiles replies, kissing Isaac playfully before pulling him out the door.

After everyone has piled into Stiles' jeep and Allison's car they start the drive to Deucalion's camp. It takes them 15 minutes to get to a point where they have to leave the cars behind and by 1am they're crouched and in position to carry out their plan.

Stage one goes off without a hitch and Lydia and Allison manage to disarm all of the traps surrounding the camp. Stage two isn't quite as easy, it involves Stiles and Danny moving in as close as they can get and wolfs bane-suffocating the guards. Right before Stiles and Danny leave, Isaac pulls Stiles aside and hugs him tightly, asking "Are you still sure?"

"I'm still sure."

"Stay safe." Isaac says before kissing him goodbye and letting him go. He looks over to where Derek is crouched behind a bush and can see tear tracks down his hard, expressionless face. Isaac isn't quite sure why they're there, but he guesses its either out of regret for what he did to Stiles or jealousy of the new relationship between Stiles and Isaac. He almost feels a pang of sympathy for him, before deciding that Derek doesn't need, or deserve it.

Stiles and Danny crawl towards the camp from opposite sides, both their target as one of the two guards who are circling the camp. Danny reaches his guard first and manages to blow a fist full of wolfs bane dust into his face before the guard spots him, the middle aged guy falls to the ground, his body limp.

On the way to the camp Scott had stopped by the vet surgery and managed to find some wolfs bane that was strong enough to basically knock out any werewolf.

When Stiles finds his young female guard she has already spotted him, he takes a chance and decided to play hurt, falling and clutching his side. When the woman reaches him she picks him up, just as Stiles had hoped, and he has a clear shot at her face, blowing the dust right at her. She too falls over and Stiles signals for the rest of his Pack to invade Deucalion's camp. They all rush in, claws and fangs out, and eyes glowing either gold, red, or in Peter's case, blue. Most of the werewolves in the new pack don't see them coming and are either dead or incapacitated in a matter of minutes, only six of the more skilled wolves and Deucalion remaining near Cora's cage, fighting although they are confused at exactly why.

The fight you'd expect from a werewolf fight such as growls, grunts and the sound of bones cracking echo across the clearing as Deucalion's pack try to figure out what's happening. Realisation strikes them when they remember about their prisoner and the fighting continues for a while, the packs fairly evenly matched.

In the end, the responsibility had fallen to Stiles to rescue Cora but he hangs back, Danny at his side for backup, because Deucalion and the what's left of his pack are surrounding her cage. Seeing the fragile, tortured looking Cora behind the fight makes Stiles glad he has Danny there because he knows he won't be able to carry her by himself.

Moments pass before Stiles gets his chance to rush to the cage and break the mountain ash circle. This is the part of the plan that had been problematic, and now thinking back, Stiles decides he should have considered the fact that Cora would be too weak to break the bars herself. He takes a shot, testing the strength of the cage and when he and Danny can't even make a dent he looks around frantically, eyes searching the crowd of werewolves for Isaac. When he finds a sweaty, concentrated looking Isaac fighting Deucalion with Scott and Erica just to his left, he breaths a sigh of relief and catches Isaac's eye, waving him over frantically. Isaac takes a final swing at the irritated looking alpha and then hurries over to Stiles' side, immediately knowing what the problem is. He smashes out three of the wooden bars in one blow, leaving scrapes across his knuckles that heal in seconds. Stiles and Danny pull Cora out of the cage with Isaacs help, and begin to half carry- half drag her out of the camp. When they reach the line of trees around the edges of the clearing Isaac lets go of Cora and breathes "I've got to go back and help, get out of here." Before running back to where Derek has now joined the fight against Deucalion. Stiles and Danny pick Cora up and are about to disappear from sight of the clearing when they hear a strangle scream, a cry that Stiles knows can only be from one person. Lydia. She was meant to stay back out of the fight and help if anyone got hurt, is Stiles' first though, before he turns around and sees her with Deucalion's arm around her throat, not quite choking her but holding her firmly. He wants to help but really, he would only make things worse so his and Danny's only choice is to stand and watch. Four of Deucalion's pack are still standing, and they are all being held down by various members of the pack, the fight at a sort of stand-still. Scott, Derek, Erica, Ethan and Aiden are all in immovable positions and can't get to Lydia without getting killed themselves. Allison has an arrow trained on Deucalion and Peter is nowhere to be seen. Isaac is the only one left who can help Lydia, but Stiles can see that he is struggling to stand, everyone can.

Isaac's arms are almost broken, not having had enough time to heal since Deucalion's last blow, he knows he needs to help Lydia but his legs give out from the pain of his injuries, and he finds himself kneeling in front of a victorious looking Deucalion with an extremely frightened Lydia in his gasp. Everything has gone quiet and the grunts and yells of the fight have died down, everyone is watching Deucalion.

"Let her go." Allison says, her voice steady but her heart racing.

"Or what? Allison you know that if I die, she dies." Deucalion replies, tracing a line across Lydia's pale throat with a long, yellow claw, his expression one of mockery.

"What if I kill you? I'm sure Lydia wouldn't mind taking one for the team." There are a few gasps at Allison's response but the rest of them can tell what she's doing, she's buying them time.

"Oh, I'm sure you'd let your best friend take one for the team wouldn't you. Allison Argent, the hunter's daughter. That little bow and arrow of yours probably wouldn't do much damage anyway, maybe I should just kill your little friend and we can all get this little conflict over and done with." Lydia make a muffled noise of terror and multiple people's muscles tense across the camp.

"I must say you did surprise me, and I'm honestly a bit pissed that my time here didn't go as planned. Cora would have made a great addition to my new pack and I have a feeling that instead of making it bigger, coming here made it decimate dramatically. What a shame that you killed them all when I could have." Deucalion continues, the eyes of both packs upon him, hateful glares and shocked expressions alike.

Deucalion has moved himself away from the centre of the fight, Lydia still in his arms breathing rapidly, and his back to the trees as if he might do a runner. There rest of the wolves, and humans, have followed, not wanting to let him get away. Isaac is almost back to full strength and is getting to his feet and mentally planning something to at least distract the alpha, when suddenly Deucalion's face goes blank, he releases Lydia, and before Isaac can react, Deucalion's upper body falls sideways, completely severed from his lower half, revealing a sword wielding Peter who is looking extremely pleased with himself, his eyes red and glinting as the morning sun peeps its head over the horizon.

After Deucalion is dead, one of the most unusual things happens, and it was pretty damn strange because this is Beacon Hills we're talking about. Peters face goes blank, he drops the bloody sword and falls to his knees, his head falling forwards. Derek rushes to his side but when has almost reached Peter he is knocked back a few meters by some sort invisible shield, like a mountain ash circle but with no visible projector or power source. They all watch as peter beings to rise, his entire body suspended above the ground as if he is a puppet with invisible strings. He lies, face down in the air for a moment before his body begins to spin, rolling over and over, faster and faster, arms flailing around in the air. There is a sudden spark of light like a camera flash and everyone shields their eyes. When they take their hands or arms away from their faces, Peter is lying on the ground face down. Derek hurries over and finds that the invisible shield has disappeared, so he moves to where Peter is lying and turns him over, his eyes widening and a small gasp escaping him as he sees Peter's face. No one is brave enough to approach the two of them so Scott settles for asking, "Derek, what happened."

It takes a moment before Derek actually realises what happened, and then another before he finds his voice and says, "He, he's young again. He looks like he did when I was in high school. I think… It must have been all of Deucalion's power, when Peter killed him it transferred into his body making him young again."

"Is he alive?" Allison asks, seeming suspicious and shocked at what just happened. As is everyone else, their faces giving them away.

"Yeah, he's breathing."

After that everything moves quickly, the remainders of Deucalion's pack run off, the twins are sulking because they weren't the ones to kill Deucalion, Lydia is scared and has the dead Alpha's blood all over her and Allison is in shock, so Scott consoles them both, Derek manages to get Peter awake and everyone is still confused as to why the power from Deucalion made him young again, Danny is just trying to process everything (as he only found out about all the supernatural stuff in Beacon Hills a few weeks ago) while trying to help a semi-conscious Cora out of the forest, Erica collects the bodies as planned and sets them all on fire as everyone begins to leave, and Isaac, well Isaac rushes to Stiles, kissing him and saying he's so glad it's over.
