Part A is finally complete. This chapter is shorter than most but I wasn't sure how to end Part A without rambling or cutting off at the wrong time. I am so sorry this has taken me a while to finish but so much has happened to me in the last year that I still haven't process it all. Part B will technically be like the shows Part A ending I guess. There are a few ideas from the last few episodes of Part A that I decided to bring into the story just changing them up a bit. It'll all make a bit more sense when you actually read Part B though.

Part A-Chapter 10

Chaos erupts immediately. Jackson jumps on Deucalion from above and the loft doors burst open. The Sheriff, Danny and Lydia busting in. Lydia runs for Isaac, Boyd and Cora while the Sheriff runs for Stiles and Danny for Scott and Allison.

At this point Deucalion has thrown Jackson away from him and turns his attention to Stiles. "You little pathetic human. You think anyone is going to help you after what they just saw?" he growls. "You think your friends are going to want to help a backstabber?"

Stiles stops and turns. Scott and Allison are already at the door. Allison has a tight grip on Scott's hand and she's whispering things into his ear. Looking at Stiles the entire time.

With a small nod Scott and her are out the door and gone.

Stiles knew that would happen and turns back to Deucalion with a shrug. "Allison and Scott are on the list. They will be taken care of later. Tonight is about you and Kali."

Deucalion shakes his head with a chuckle. "What makes you think you can beat me? Four humans and a werewolf? You don't stand a chance."

It's Stiles' turn to shake his head with a chuckle. "It's three werewolves by the way and you shouldn't underestimate humans Deucalion. We don't need to beat you, only outsmart you."

"Agh!"

Deucalion spins around and sees Ethan and Aiden immerged as their Alpha holding Kali by the throat. "What do you think you're doing?!" he shouts.

"What's right." Their nails rip right across Kali's throat.

"No!" Deucalion's entire face begins to distort. Change. But not in the normal way. "I am the demon wolf!" he screams.

Deucalion spins and charges for the twins. Stiles goes to run after him but three sets of arms circle around him. He begins fighting against them. Struggling and shouting. His father, Jackson and Danny run over to help him but by then it's too late.

Deucalion grabs the twin Alpha's head and literally rips them in half. Back into two separate bodies. The twins fall off to the side, their eyes burning Omega blue before flickering out and fading away. Stiles screams and struggles even more.

"It's what they deserve." A voice, which sounds like Boyd's, growls in his ear before finally releasing him to fall to the floor.

Stiles immediately runs over to Ethan while believe it or not Isaac runs to Aiden. He sets his fingers against Ethan's throat and barely feels a pulse. "Lydia, Danny go get Deaton! Their alive but just barely. We need his help." Stiles shouts.

Stiles stands up and turns around only to have his breath catch and his heart stop. Deucalion has his nails posed against Derek's throat and a devilish smile on his face. "Don't move." he warns.

Stiles nods and even backs away a step. "Why are you doing this Deucalion?"

Deucalion laughs and there's nothing human about it. "Why? Why?! For power you idiot! I want more! I want an unlimited supply! I want it all! People, human and werewolf alike will fear me by the time I'm done getting what I want."

"Why Derek? Why his pack?" Stiles needs to keep him talking so his nails don't end up across Derek's throat.

"Why else? He's a Hale and an Alpha to boot. I want his power. With the power of a Hale Alpha in me I could take down the rest of your little pack no problem."

Deucalion turns his attention back to Derek. "You should have joined me." he whispers before his claws swipe right across.

"NO!" Stiles screams with all his might, squeezing his eyes shut.

Seconds, minutes, hours, maybe even days pass before someone whispers a disbelieving 'What!'.

Stiles' eyes snap open and he gasps. A silvery see-through shield? is wrapped around Derek like protection and Deucalion is laying several feet away struggling to his feet. Deucalion stands. "Well well well…" he says.

Stiles is breathing heavy and he has no idea what's going on. This isn't what he and Deaton studied the other night. "I…" he trails off as he looks at Derek.

Derek is staring at him wide-eyed. Even Peter looks shocked. Deucalion chuckles again and shakes his head. "You don't even know do you?" he asks with what sounds like pity in his voice.

"Know what?" Stiles can't help but ask.

Deucalion sighs. "Only a Pure Soul can shield another Soul from death."

"What does that mean?"

Deucalion smiles. "It means you have more power inside you than you can possibly imagine. And soon, that power will be mine." Without another word Deucalion turns and jumps through the large window disappearing.

~! #$%& !~

"Can you save them?"

Thirty minutes later Derek, Jackson, Isaac and Boyd lift the twins onto two metal tables in Deaton's office while Stiles, his father, Lydia and Peter gather the supplies Deaton instructed them to.

Deaton nods. "It's cutting a bit close but you brought them just in time. They will live when I'm done with them but they will need rest and a safe place to go."

"My parent's place is empty, they can rest there." Jackson offers.

Deaton nods. "That will do just fine. I need everyone out while I do this. Stiles you may stay if you like."

Stiles shakes his head gently. "I have some explaining to do. We'll talk as soon as the twins are in recovery." Deaton nods again and sets to work on what he needs to do.

Stiles follows everyone but Cora into the waiting room. After Deucalion escaped Cora grabbed her bag, said goodbye to Derek and Peter and skipped town before anyone else could blink. Stiles has no idea where she plans on going but he hopes she makes it their safe.

As soon as everyone is in the waiting room Derek spins on Stiles and growls. "What the hell happened tonight?"

Stiles narrows his eyes at Derek but doesn't back down. "What happened was me doing what needed to be done in order to save the people I care about Derek."

"Then what the hell was that tape all about?" Boyd growls behind Derek.

Stiles snaps his head around and glares at Boyd with all his might. "You're the reason Ethan and Aiden are in there right now Boyd so why don't you shut the fuck up and sit down before I make you!" he shouts.

Boyd's eyes widen and he takes a step back. Jackson smirks and elbows him down into a nearby chair and the Sheriff adjusts his grip on the gun he's holding. Danny and Lydia have their arms crossed and if looks could kill Danny would have stuck Boyd down by now. Isaac is trying to make himself look small in the corner of the room. Not sure whose side he should be on.

Stiles turns his attention back to Derek but answers Boyd's question anyway. "The tape was of me approaching Ethan in Jungle to ask him for his help in taking Deucalion and Kali down and his help on getting Aiden to see the truth and join his brother in doing the right thing. If any of you really think that I would join anyone to take any of you down then you don't really know me. I care about everyone in this room and I would never harm you or help someone else harm you. The only reason you're alive right now Boyd is because Ethan didn't want to kill you and distracted them long enough for Deucalion's plan to fail."

Stiles sighs and rubs his head. There's a headache forming and he's feeling very jittery. He knew the repercussions of his actions would be on the not-so-good side but he honestly didn't think everyone would automatically assume he would betray all of them and help to try and get them killed. No one in Derek's pack has any trust what-so-ever. He knows they all have good reasons for it but Stiles has done nothing but follow them around, do whatever they want and save all of their asses on more than one occasion.

"Look, I don't really care if any of you believe me or not. I don't. I'm done running after all of you," he points to Derek, Peter, Boyd and Isaac when he says this. "doing whatever you want and helping you in every way I can. Especially because all of you do nothing but treat me like shit and push me away."

Isaac whines from the corner and ducks his head down when everyone turns to look at him. Stiles blinks in surprise when Boyd echo's the sound and also ducks his head down. Stiles' blinks turns into gaping when both Boyd and Isaac tilt their heads and bare their throats to him.

Stiles immediately points to Jackson, Lydia and Danny who are smirking. "Not a word or I swear to god…"

"You'll rip our throats out?" Lydia asks sweetly.

"With your teeth?" Jackson adds helpfully.

Danny outright laughs while Stiles groans and buries his head in his hands. "I hate all of you and I'm not the god damned Alpha!"

It's Peter that cuts in this time. "Actually. From what I've seen, you are. You have your very own pack and you organized this entire plan just to help save another pack. One that's not your own."

"No offense but I didn't do it just for you guys, I did it for my friends as well. We were all, still are actually, in danger." Stiles protests but even he can tell it's weak to his own ears.

"I understand that Stiles but your friends weren't in as much danger as Derek and us. the Alpha pack would have only gone after people in Derek's pack because that's how Derek would have gained more power. By killing his own beta's not random teenagers. You chose to stand up and fight for Derek and his pack all on your own. That's what makes you an Alpha. And apparently a Pure Soul." Peter finishes.

Stiles sighs irritated. "Fine. Whatever. I'm the Alpha. Happy?" he demands.

Immediately Stiles is instantly crushed against four people. He 'oomphs' and chuckles. "You guys are weird." He mutters but hugs them all back anyway.

"You love it." they all say.

Boyd is the first to pull back. He scratches the back of his head and glances first at Stiles, then Derek and then the closed door to the examination room. "I owe them both apologies. Their Beta's now because of me." he sounds ashamed and Stiles smiles gently at him.

"They'll be fine and trust me when I say there probably won't be any hard feelings. Neither of them wanted to be Alpha's anyway. If they could go back without dying they would, you just helped them do it. The important thing is that we got them here in time and after some well needed rest they will be back to their normal pain in the ass selves." Stiles claps Boyd on the shoulder and turns back to Derek and Peter.

"Look Derek, I'm sorry I didn't include you in on the plan but, no offense, you're easy to read. You really are. You spend so much time trying to hide your feeling and what you're thinking that it shows all over your face."

Derek opens his mouth to respond but doesn't get the chance because at that moment Deaton opens the examination door. "Stiles. Your new Beta's are awake and they need their pack." he stares.

Jackson, Lydia, Danny, The Sheriff and surprisingly everyone else immediately follows Stiles into the room and crowd around the newly transformed Beta's. Stiles stands between the two tables and places his hands on both Ethan and Aiden's shoulders. "How do you feel?" he asks gently.

Ethan blinks his eyes open slowly and sends Stiles a small smile before seeking out his boyfriend. Danny immediately grabs Ethan's hand and kisses his forehead. Stiles turns to Aiden and smirks when he sees Isaac already at his side checking on him. Stiles clears his throat and raises his eyebrow when Isaac's head snaps up. He blushes deep red and moves to hide behind Boyd. "How do you feel?"

Aiden sends him a smirk. "Day or two and I'll be good Alpha Stiles."

Stiles moves his hands from their shoulders to their necks and rubs over their pulse points. He looks up at his father. "Is it alright if we puppy pile at Jackson's house for a few days. I can't stand them being like this."

John gives his son a soft smile and nods his head. "Of course. I may not understand everything yet but I definitely understand Alpha and Beta dynamics son."

Stiles smiles and nods. "Thanks dad." he turns to Deaton. "Can we take them?"

Deaton nods. "They should be fine to leave. They're going to need help walking for a bit but they can move."

"Thanks Doc. I'm gonna get these guys to Jackson's and get them settled in. I'll come back in a bit and we'll talk alright?"

"Of course. Take all the time you need. I'll be here for a while tonight. I have a lot to get done myself."

Stiles nods and then signals for Danny and Jackson to help Ethan up. When he turns to instruct Lydia and his dad to grab Aiden he finds Boyd and Isaac already doing it. Isaac bites his bottom lip and turns puppy eyes on Stiles. "Can we come too?"

"Of course you can. As long as it's okay with Derek."

"I'm fine with it because I'm coming too." He states immediately.

Stiles nods. "Let's go then. I don't want to chance running into the Darach or Deucalion tonight." he shudders. Not so much at the thought of Deucalion but of the Darach. Deaton and he spent a lot of time going over information on the Darach and the sacrifices and what he might need to do in order to take it out.

With one last farewell to Deaton the two packs head to their cars and speed to Jackson's.

~! #$%& !~

Stiles sighs and sips his coffee as he watches the sun begin to rise through Jackson's glass kitchen wall. It's been a very long night and Stiles hasn't slept a wink. The other members of the two packs are in the living room puppy piling it on a bunch of mattresses left over in the bedrooms fast asleep. Stiles had to wait until he knew they were really asleep to get up and go see Deaton. Once they got to Jackson's no one wanted him to leave.

On any other time he would have stayed and slept with them but Deaton had information he needed and he had to make sure no one would follow him to the clinic and listen in.

Movement in the doorway makes his head snap away from the rising sun and straight at Derek. "Morning." He says automatically.

Derek nods in greeting and heads over to the coffee machine to poor himself a glass. When he's done he moves to sit in front of Stiles at the kitchen table. Stiles is currently perched on the counter. His favorite spot to sit in any kitchen really.

"We need to talk." Derek says.
