Derek had messaged Isaac saying they were going to be at the loft apartment rather than the warehouse. Isaac was about to unlock the door when he heard a crash from inside and high pitched shouting. Cora? He listened closer and frowned.

"Derek you haven't even apologised to him! How is that fair? And I know you've been with him at some point because I can smell him all over you!" Cora shouted. Something crashed against a wall - a stool maybe?

"Cora shut up, I don't have time for this!" Derek had snapped at her. Isaac heard Derek slam a door and walk down the stairs. He sighed, opening the door to be greeted by Derek storming out.

"I'm guessing you heard that. And I would say I'm sorry for kicking you out the way I did, but honestly I'm not sorry because I did it to protect you." Derek said, still clearly furious because of Cora.

"Hey, it's okay; I don't mind that you kicked me out" Isaac says, putting his hand on Derek's shoulder. He had never seen Derek as angry as this before - especially not because of something that had been said. He usually had complete control over his emotions.

Derek sighed, trying to control his anger. "Can we go back to the warehouse? I don't think I'll be able to go back in there without ripping Cora to pieces"

Isaac nodded, following Derek to his car. He dumped his bag in the back seat before climbing into the front seat next to Derek.

They hadn't spoken at all on the way to the warehouse and that worried Isaac a little. He felt like it was his fault that Derek had fought with his sister so naturally he was flooded with guilt. Derek sensed that Isaac was blaming himself so he smiled weakly

"Don't blame yourself for what happened, she just doesn't understand and I think she might be jealous that I have a boyfriend when she doesn't." His attempt to blow it off worked though because Isaac smiled

"What did she mean when she said she could smell me all over you?" Isaac asked, grinning slightly.

"I think I fell asleep after you left and the next thing I know, she's phoning me and demanding that I go see her. I didn't get a chance to shower or anything because she said I had five minutes to get to the apartment before she hunted me down" he said, shrugging. "I don't mind that I smell like you anyway" he mumbled after a moment.

"Couldn't have been as bad as Scott saying I smelt like you and sex" Isaac chuckled. He found it quite amusing that all the werewolves they had talked to lately had noticed how they smelt like each other.

"What did you say?" Derek asked, unsure if he wanted to know or not.

"I said nothing happened, which by the way, is such a disappointment." Isaac mumbled, suddenly shy.

"Aw did little Isaac want me in his pants?" Derek teased, laughing quietly.

"Yes I did, and I still do but I think sleeping would be good enough" Isaac blushed, feeling really embarrassed for even saying that he wanted Derek in his pants. He couldn't deny it though because even if he had lied and said no, Derek would know the truth because his heartbeat would give it away or if not then he'd probably have blushed or something.

"You'll probably get what you want soon so let's get you to bed" Derek said, smiling softly at Isaac as he got out of the car.

Isaac opened the door slowly and he was even slower when he retrieved his bag from the back seat. He seemed to be struggling to walk while he carried his bag. Derek frowned - even though he was tired, he shouldn't have been struggling this much.

Derek walked to Isaac and took his bag from him, it didn't make much difference though.

"Isaac... are you okay?" he was extremely concerned for Isaac.

"I don't - I don't know" Isaac frowned. He felt drained and his still unhealed wounds felt extremely uncomfortable. He realised that he should have healed way before now. "Derek... Derek I still haven't healed. That's not normal is it?" He was clearly frightened and confused.

"No it's not. I think that maybe Ethan used wolfsbane somehow when you were fighting - that's the only possible explanation as to why you aren't healing"

"I don't feel so good" Isaac mumbled. He didn't look well either but Derek didn't want to say anything.

"I know, and you'll feel worse in a few minutes because I need to trigger the healing process..."

"You need to break a few of my bones" Isaac said, he'd seen this happen only once before now and it looked seriously painful.

Once inside, Derek dumped Isaac's bag and wrapped one arm around his waist, guiding him to the bed. He grabbed Isaac's arm, mumbling apologies before he made the first snap. Isaac had managed to stay quiet even though the pain of having his wrist broken was almost unbearable. Derek moved up to the middle of his forearm, snapping it with ease. Isaac screamed with the pain this time. He leaned into Derek's shoulder, groaning with the immense pain shooting through his arm.

"You're enjoying this" he said, more of a statement than a question.

"I'm not, I swear" Derek said, trying to be sincere but humor was an obvious undertone.

"Yes you are" Isaac said through a groan and a laugh.

"I don't like hurting you, but I have to admit that it's kinda fun to snap bones" he said as he snapped another bone in Isaac's arm.

Isaac, who still had his face leaning into Derek's shoulder, practically sunk his teeth into him because he wasn't expecting Derek to snap his arm again. Derek heard a lot of muffled "fuck"s coming from Isaac and he felt really bad. He didn't think he needed to snap that bone, but he had to take precautions to make sure Isaac would heal. He pulled his boyfriend's face from his shoulder and frowned, seeing the bloody mess on his face. Isaac smiled weakly,

"You're so lucky I bit my lip and not your shoulder" he mumbled, trying to be funny. Derek's frown deepened.

"I'd rather you bit my shoulder. It looks like your fangs have pierced through your lip" he mutters. He leaves Isaac for a minute and returns with a bowl of water and a cloth. He wipes the blood from Isaac's face quickly but gently.

"Shirt off" he commands, watching Isaac comply. Derek snaps all the stitches at once, making sure no thread was left to hold the wounds together. He smiles slightly when he sees the tissue reforming. Isaac was healing.

Even after Isaac had finished healing, Derek was staring. He only stopped when Isaac started laughing

"Why are you staring at me? You have a funny expression on your face" he manages through his laughter.

"Cute" Derek grins, looking up at Isaac. "I'm staring because you are utterly fascinating, and that 'funny expression' is because I'm fantasizing inappropriate things" he says matter of factly. Isaac rolled his eyes; he would have liked a more specific answer.

He suddenly had a mischievous grin on his face. He grabbed Derek's arms and dragged him down onto the bed. He quickly climbed on top of Derek, pinning him down. Leaning close to Derek, he let out a low growl. Derek had gotten over the fact that he'd been pinned down; his expression gave away the pure lust and wanting he had for Isaac. Isaac smirked, leaning in closer to Derek, his voice was like gravel when he spoke

"I can be a tease when I feel like it too, just remember that"

He climbed off of Derek and yawned as if nothing had happened. He went to the bathroom and came out a few minutes later, smelling like mint toothpaste. That wasn't what caught Derek's attention though. It was the fact that he was in nothing but his boxers. He yawned again as he climbed into the bed. He really was tired.

Derek joined him after a while and he felt at peace again. He wrapped his arms around Derek and rested his head on his boyfriend's chest. He was lulled to sleep by the rhythmic sound of Derek's heartbeat.
