deal with the devil

|Martin house|

Lydia shoots up, breathing erratically and covered in sweat.

"Lydia?" Scott asks drowsily, waking up by her sudden movement.

"Sorry, it's just I had a nightmare about Peter, now that he's going to come back tonight." Lydia tells him out of breath.

"Shh. It'll be OK. He won't get to you ever again." Scott tells her, rubbing her back soothingly.

"Promise?" Lydia asks scared.

"Yes. I promise." Scott tells her, kissing the hand she's clutching his own with.

"Come on, try to get some more sleep. You have to throw the biggest party of the year later after all." Scott says trying to lighten her mood.

"You're right. I'll try to get some more sleep." Lydia agrees and lies down hugging herself close to Scott, who puts his arm around her and gives her a kiss on top of her head.

|Dereks hideout – a few hours later|

"What is that?" Isaac asks seeing the symbol on the chest Derek just popped open.

"It's a triskele. The spirals mean different things. Past, present, future. Mother, father, child." Boyd answers.

"You know what it means to me?" Derek asks.

"Alpha, beta, omega?" Boyd guesses.

"That's right. It's a spiral, it reminds us that we can all rise or fall to another." Derek replies slightly surprised.

"You mean like Scott?" Isaac asks.

"Sure, he's a freak case though. But he's with us." Derek replies.

"Really? Where is he now?" Isaac asks.

"He's trying to find out who the master is, and he won't have it easy tonight either." Derek says.

"Through your powers you have the ability to heal but tonight you're going to want to murder anything you can find." Derek tells them, handing out some containment devices, covered with bolts and chains.

|A while later at the Argents|

Lydia arrives in Allisons room, carrying multiple bags of clothes, grinning widely as she tells her "Clear your schedule, this is going to take a while."

"How many outfits do you plan on wearing tonight?" Allison asks looking at the amount of clothes her best friend brought.

"It's my birthday party, I'm thinking host dress. Evening dress, maybe after hours casual." Lydia replies playfully.

"I noticed that you didn't send out any invites." Allison says.

"It's the biggest party of the year Allison, everyone knows, and Scott actually used his co-captain status to remind people to come." Lydia informs her.

"I was wondering if this year, things might be different?" Allison asks.

"Why would anything be different?" Lydia asks back.

"Just because you've been through much lately. I would have thought you might have wanted to take it easy." Allison replies.

"Are you kidding? Lydia Martin not throwing a party? It'd be like feeding the piranhas." Lydia tells her.

Anyways, here. This one is for you." Lydia says handing her a dress she picked out for Allison, when Allisons mother knocks on the door, standing in it's frame.

"Oh hey, Mrs. Argent, what do you think of this one?" Lydia asks holding up a short blue dress to herself.

"It's lovely. Allison, can I grab you for a moment to talk?" Victoria asks.

"Can we do it later?" Allison asks.

"Uhh, actually to be honest, sooner would be better." Victoria tells her.

"Party is at ten." Lydia informs her best friend's mother.

"You'll be around before then?" Victoria asks.

"I think so." Allison replies and Victoria leaves the two girls alone.

|Meanwhile with Stiles|

"Hey, what're you doing?" Noah asks his son.

"Homework." Stiles tells him.

"It's spring break." Noah says.

"Yeah, well let me indulge my curiosity." Stiles tells him.

"Look Stiles, I know you`re trying to solve this for me but you really don't have to." Noah says.

"But I have to do something, something is missing." Stiles replies while going through the yearbooks.

"Stiles. Look at the swim team." Noah tells his son, seeing a picture on the current page.

Stiles sees all of the victims were on the swim team and adds "Dad, look at the coach, it's Isaac's dad." Stiles says.

|That evening at the Martin's house|

Scott is helping Lydia set things up for the party and talking about their plan with Derek.

"And you're sure you're going to be alright alone?" Scott asks her worried.

"Yes. Scott, you're already helping me get rid of this psycho's ghost, you don't need to worry to keep me save at my own party." Lydia says kissing his cheek.

"I know, today is just the full moon and I can't help but worry for you." Scott replies.

"Anyways, since I won't come back until well after midnight, how about I give you your present now?" Scott offers with a grin.

"We can wait until later." Lydia says.

"No, come on. I want you to receive it on your actual birthday, so happy birthday Lydia." Scott tells her, giving her a loving kiss and hands her two relatively small wrapped presents.

"Thanks, you didn't have to get me anything though." Lydia tells him.

"I wanted to." Scott says and watches her as she opens the presents.

"It's beautiful, want to help me put it on?" Lydia says looking at a silver necklace with a hawk on it.

"Sure." Scott says relieved that she likes it and hangs it around her neck.

"Let's see what's in here." Lydia says opening the second present and sees a beautiful looking dagger inside.

"Huh?" Lydia asks confused, picking it up.

"I know it is a little weird but pull it out." Scott tells her, still standing behind her and rubbing her arms.

"OK?" Lydia agrees still confused.

"Isn't that?" Lydia asks seeing what looks like a Oversized Talon instead of a blade.

"Yep, remember the other day when I was missing a nail, that is the reason. Deaton had the idea, I tried to concentrate on the Kanima's venom when I cut it off and in theory it should have it's venom imprinted on it." Scott tells her.

"So, what am I supposed to do with that?" Lydia asks.

"Since you're the only other person to be immune to his poison I thought it'd be the perfect weapon to defend yourself with or just carry around when you're scared. I'd be like a piece of me is with you." Scott tells her.

"I guess, that's actually rather thoughtful." Lydia says, turning around in his arms and locking her arms behind his head, pulling him in for a kiss.

"Thank you." She whispers, lying her head against his chest while hugging him.

"You're welcome. And don't worry, the next present won't be another weapon." Scott chuckles.

"Oh, thank god, still I love it." Lydia says.

About an hour later Lydia's party is in full swing when Scott feels the moon coming up gradually.

Upon receiving a phone call from Derek asking him for help with his betas Scott goes over to Lydia and tells her that he's going now. She wishes him luck and tells him that he should come through the window again. After Scott left the party continues on for another hour or at most two, until the police start to show up breaking it up and in the stream of partiers fleeing Matt gets thrown into the pool while yelling that he can't swim, making Lydia and Stiles look at him thoughtful.

"You don't think?" Lydia asks her boyfriend's best friend.

"I think so. He had enough opportunity." Stiles replies, while some people help Matt out of the water and once, he's out he stares at them angrily, until the Kanima appears and takes him away in the blink of an eye.

"Oh crap." Stiles says.

|Meanwhile at the Argent's|

Victoria has to take her own life after writing Allison a goodbye letter and with her husbands help, she kills herself with a knife before she has the opportunity to turn, despite her husbands' pleads to reconsider.

|With Derek|

Derek chained up his beta's before the moon came up and is fastening the chains on them once again when he feels the moon rising to its peak.

"How are you not feeling this?" Isaac asks while Derek works on his bindings.

"I'm feeling every second of it." Derek replies.

"And how do you control it?" Isaac asks.

"Find an anchor, something meaningful to you. Bind yourself to it and it keeps you in control." Derek tells him.

"What is it for you?" Isaac asks.

"Anger. But doesn't have to be that for everybody." Derek replies.

"Certainly not. My anchor is Lydia." Scott agrees.

"No surprise there." Derek murmurs.

"So how can I help?" Scott asks and the three of them hear growling coming from the other betas in the trailer.

"How about you take one of them and I take the other? Isaac seems to still be in control, if he loses it, I'll take care of him as well." Derek suggests.

"Alright, I'm on Boyd." Scott agrees and gets ready to fight the larger werewolf.

Isaac also turns and rips himself free, jumping out of the trailer. Erica and Boyd also managed to free themselves and are charging at the two alphas.

"You want to take Erica and Isaac outside?" Scott asks, still staying in his human form.

"Sure." Derek says and picks up Erica, throwing her after Isaac out of the window while Boyd charges at Scott, who starts to fight back.

"Boyd I don't want to have to hurt you." Scott grunts, hitting boyd with a punch to the neck after dodging a wide swing from him.

Boyd retaliates by spearing Scott, making them crash onto the floor of the trailer and Boyd starts to claw at Scott wildly until Scott's eyes glow red and he starts to shift, giving Boyd a powerful headbutt, knocking him out for a short time.

Derek, having dealt with Erica, with Isaac's help surprisingly also comes into the trailer and chains both of them back up.

He chains up Isaac as well just to be sure and the two alphas go outside to talk.

"Thanks. I'd have had my hands full with all three of them." Derek says.

"No problem. Just one thing." Scott replies.

"What?" Derek asks.

"I'm sorry and don't take this personally." Scott says and shifts, hitting Derek's neck with full strength, knocking him out.

"Great, now how do I get him to his house? Oh man I should've seen this." Scott sighs and picks Derek up, putting him over his shoulders and carries him to his old home, where he has already dug up Peter's body and prepared an array of mirrors to shine moonlight on Peter.

"Scott, don't." Derek says weakly, being tied up at the moment.

"Derek, I have to Peter is hurting Lydia unless I bring him back." Scott says sounding genuinely defeated.

"I understand." Derek replies thinking back to his own first love.

"Deaton said you'd be safe and that Peter won't pose a threat, for now at least." Scott tells him and takes his arm, putting it in Peter's hand before shining the moonlight on them.

After a minute or so Peter is back alive and Derek is out cold.

"Thanks for bringing me back Scott." Peter says amused.

"Remember, one move towards Lydia and I'll rip you apart." Scott threatens him, shifting into his full Were- Eagle form, hovering over the reborn wolf and poising his clawed feet at him.

"Well that is new." Peter says impressed.

"What was yours is now mine." Scott tells him, showing him the glowing Talons and screeches at Peter.

Scott then picks up Derek and makes his way back to Derek's hideout after losing his transformation.

After Lydia's party Allison was called to the hospital by her father, who is waiting for her in front of a room where his wife's body is lying.

"No. No, dad if this is some kind of sick training session…" Allison says before she loses her breath and cries hysterically, hugging her father for support.

|around 2 am|

Scott arrives at the Martin's house and looks around, seeing no one and shifts his wings so he can fly up to Lydia's window. Finding it open he gets in and closes it behind him quietly before he takes off his now ruined shirt, thanks to Boyd's claw marks and his dirtied pants and shoes. After he's ready to get to bed he feels two soft arms encircling him.

"Hey." Lydia whispers into his ear from behind.

"Hey." Scott says back grinning to himself.

"How'd it go?" Lydia asks.

"No one was killed curtesy or Boyd, Isaac or Erica and Derek actually was OK with what I had to do once I told him that Peter held you hostage." Scott says, giving her a quick peck on her cheek, climbing into bed next to her afterwards.

"How was the rest of your party?" Scott asks.

"Eventful. The police broke it up actually and Matt is the Kanima's master." Lydia says.

"Come again?" Scott asks shocked.

"Yeah, he fell into the water and was panicking about not being able to swim and after he got out the Kanima suddenly appeared and both vanished together.

"freaky?" Scott asks.

"Most definitely and Stiles and I agree, he's the master and you know how rare it is we see eye to eye." Lydia replies.

"Haha, well let's deal with it later. Happy birthday again Lydia." Scott tells her, hugging her close to him and giving her one last passion filled kiss.
