A/N: very loosely based off 3x09: The Girl Who Knew Too Much

To put it simply, Isaac had a shitty day. He was extremely close to ripping Aiden to shreds at one point because of what he was saying - apparently word of Cora's little stunt had traveled fast... Unless they were being watched by someone in the alpha pack... Isaac had recently started keeping a small amount of wolfsbane with him in case he was in a fight with another werewolf; using wolfsbane to stop the healing process seemed like a good idea anyway. He was in the now empty locker room with Aiden so when he slipped his hands into his pockets to cover his claws, mere feet away from Aiden, he had the most psychotic grin on his face. Aiden had looked at him in confusion before being met with claws sinking deep into his skin and being dragged quickly downwards. Aiden controlled himself fairly quickly after the few seconds of shock from being injured by the beta. His hands were swiftly wrapped around Isaac's neck with such brutality that Isaac could practically feel the bruises forming already as he was lifted off his feet. He figured it wouldn't take long for Scott or Stiles or maybe even Ethan to get to the locker room if they heard anything. They weren't far anyway - out on the field with Finstock rambling on about how they should put more effort into their other classes so they would still be allowed to play lacrosse when it came into season and so on. He figured he'd have maybe two minutes before blacking out if Aiden continued to keep a vice like grip around his throat; that is, unless Aiden decides to actually fight or snap his neck. He never go the chance to find out though because Scott and Ethan burst into the locker rooms to a gruesome sight - Aiden was dripping blood and he looked strangely smug while he was choking Isaac. What was worse was the quiet, manic laughter coming from the beta. He was... taunting the alpha? Aiden released Isaac begrudgingly as he turned to his brother who looked in as much pain as he felt. Scott was by Isaac's side immediately to make sure Isaac had someone to back him up but also partially to restrain him from attacking Aiden again. Isaac was still laughing; he looked increasingly scarier as the seconds past. Ethan was staring at him incredulously as if Isaac had lost his mind.

"Neat trick you pulled there but why hasn't he started healing yet?" Ethan asked curiously. Maybe he hadn't known his claws were laced with wolfsbane when he'd fought with Isaac.

"Isn't it obvious?" he'd said in such an innocent tone. Scott shook his head, thinking that Isaac must be having a bad day if he was being like this with two alphas who could and would kill him in seconds if given the chance.

"He used wolfsbane. It stops the healing process so if you want your brother to heal you should probably decide which bones to snap soon before he bleeds out. It's also a good idea to snap a few bones to make sure the healing process is properly triggered." Scott explained to Ethan who nodded but seemed reluctant to break a few of his brother's bones - probably because he's be in as much pain as Aiden when he had to do it.

Isaac and Scott left the locker room when they heard the first snap. Once they'd joined Stiles where Finstock was still lecturing the class, Scott turned to Isaac.

"What the hell were you thinking? You know he could have killed you" Scott was furious but he couldn't convey all of his anger towards Isaac when he had to whisper in case someone heard them.

"He started it" Isaac mumbled. It was like dealing with a five year old.

"You're not meant to let it get to you though, especially since it's amusing to him and if Cora finds out why you attacked him she'll think it's hilarious too" Scott replied icily. Isaac nodded and kept his gaze towards the ground. He stayed silent for a long time.

"You looked really god damn scary with all the psycho laughing and stuff" Scott muttered, trying to be a little less serious.

"It was all part of my master plan" Isaac replies. He was lying but managed to keep his heartbeat even so Scott wouldn't suspect anything. Honestly he had no idea where the psychotic outburst came from.

His day at school was drawn to an end with Cora punching him square in his jaw; subsequently breaking it with the amount of force used. All he'd said was that she could pass as a slut if she wanted to. This was apparently the wrong thing to say. Luckily, no one had seen the small exchange except for Scott and Stiles.

When they exited the building and headed to where Scott's bike and Stiles' jeep were parked, Isaac's jaw had healed and he had started laughing quietly. Derek looked like he was asleep in his car... in fact, he had parked it in exactly the same spot as that morning - between Lydia and Stiles' cars. As he neared the car he tried stifling his laughter because Derek actually was asleep.

Isaac opened the door of the car with a smirk playing on his lips. He shook Derek's shoulder softly in an attempt to wake him. His boyfriend grumbled in protest as he began to wake up.

"Why'd you let me go to sleep in the damn chair?" Derek grumbled as he shifted to his left only to hit his head on the car door frame. He realised where he was once Isaac, Scott and Stiles started laughing. He glared at them murderously, muttering the familiar "I'll rip your throats out with my teeth" as he began to sulk. Stiles was practically doubled over from laughing; the more he tried to compose himself, the worse his laughter got. He did eventually stop though.

"Are we, are we still planning stuff tonight?" he pants, slightly out of breath from the laughing. Derek refused to answer. Instead, he looked out the window as if there was something extremely interesting sitting beyond the glass. "Sourwolf" Stiles muttered as he turned to look at Isaac.

"The recital is tonight so we might as well skip it to plan?" Isaac says, shrugging. Stiles looked as if he was working out everything; fitting pieces of the puzzle together.

"The darach is going after philosophers now. It got Deputy Tara and Mr. Westover today - Lydia was the one who noticed... She, ah.. wrote the number two on the chalk board before screaming her head off or something.. Anyway, the darach will probably be at the recital since it's going to be full of teachers" Stiles says slowly, working things out further.

"Right, of course" Isaac muttered. He was the one sulking now and the annoyance and slight anger was radiating off of him. None of his friends or boyfriend decided to question his sudden change of mood.

Isaac had blanked out after that, and only realised he had no memory of the rest of the conversation nor leaving the school when Derek had parked his car outside of the warehouse. Crap.

He was completely disorientated and for the first time in a long while, he was scared of his own messed up head. His hands came up to his head where his nails found his scalp. Old habits never die, he guessed. He used to do this almost constantly before Derek had found him and the fact it was starting again clearly wasn't a good sign. He must have really been digging his nails into his head because the sickening iron aroma of blood had filled the car. He removed his hands from his head immediately, feeling stupid for letting something like blanking out cause him to go back to his old habits. He then realised he was rocking back and forth slowly in the seat. This was not good.

Derek had been frozen, unable to think of a way to help Isaac let alone snap him out of the trance-like state he was in. He was extremely concerned about his boyfriend and could only assume this was something he might have done before.. when he still lived with his father. It was the heartwrenching sobs which finally broke Derek from his paralysis. He wrapped his arms around Isaac in an attempt to comfort him. He put as much energy as possible into the hug, hoping it would calm Isaac down a little.

"Hey, it's okay. You're okay." Derek murmured, his voice muffled against Isaac's hair. He kept repeating this for a long time as he waited for the sobbing to subside. When the only sound in the car was their breathing, Derek pulled back from the hug and held Isaac at arms length. Isaac avoided making eye contact, instead opting to look down and mumble an apology.

Derek decided a more comforting environment would be best for talking to Isaac about what had just happened - he warehouse was not the place to talk. Wordlessly, Derek ignited the engine and started driving in the direction of the loft apartment.

A/N: oh my god i'm so sorry for the long wait! i thought i'd have finished this chapter before 3x10 was aired but it looks like it's taken longer than that due to my writers block. i was going to finish this chapter all at once, ending it similarly to 3x12(once i realised i wasn't going to finish it before that episode) but unfortunately i'm out of ideas and i honestly struggled to write this chapter, let alone write it to include parts from another three episodes! so i decided i'd split it into three or so parts so that it's easier to write. i'm thinking once i finish the separate parts that i'll end this fic? unfortunately i don't know when that will be because school will be starting september 3rd so i'll have even less time to write.

again, i'm so so sorry for the long wait! i'll try to make it up to you guys by possibly writing and posting part two tomorrow?

by the way thank you guys for reading! ily all x
