Derek entered his apartment and is shocked to Stiles there, considering the teen said he would be having a guys' night with Scott. Immediately Derek can sense something is wrong. Stiles is rolling off a wave of emotions: anxiety, fear and nervousness. The lycan sets his keys down on the keys down on the kitchen counter his back to the teen, "Stiles, why do I have this feeling I'm not going to like this conversation."

Stiles intakes a deep breathe. "I-I…well-"

Hold on this will hurt more than anything has before
What it was, what it was, what it was

"I…I..something happened between me and Danny"

Derek slammed his fist down on the counter tap, a crack appearing on the granite and causing Stiles to jump. "When?" the lycan growled out

"It's," Stiles breathed out "It's been going on for a while."

I've brought this on us more than anyone could ignore
What I've done, what I've done, what I've done

"How long?" the older man growled out.

Stiles let out a shaky breathe. "Three days"

Derek walked away, his eyes flashed blue as he tried to keep the wolf at bay. He didn't want to wolf out in front of Stiles, if he did it meant he lost control. He didn't want to lose control and as much as he wanted to dominate the teen, to show him his place, he couldn't. He loved him too much.

"Der," Stiles called out, panic evident in his tone

Derek turned around, and his eyes were shut tight. "Don't call me that."

"Sounds fair."

"Just, God, Stiles why!"

I've worked for so long just to see you mess around
What you've done, what you've done, what you've done

Stiles backed up his breathing hitched in his throat. Derek was crying. The older man's shoulder shook as he tried to keep himself composed.

"I don't understand Stiles we've been together for almost a year. And we went through a hell of a lot to get to where we are now!"

"I..I don't-"

"Stiles, God damn it, I didn't go the whole nine yards for you to say I don't know!" Derek growled out

I want back the years that you took when I was young
I was young, I was young, but it's done

"I know, Derek I know," Stiles whimpered out.

"So when you were with Scott last week, were you with him?"

Stiles didn't need to answer, his heartbeat gave it away and Derek could feel the guilt that entered the atmosphere.
Stiles didn't know what else to say and he watched as Derek broke down. The lycan let out a frustrated growl, his eyes flashed blue as his fist connected with the wall. Stiles jumped a stream of I'm sorry escaped his mouth as Derek let out an anguish cry.

Oh take it all away
I don't feel it anymore
Oh take it all away
Oh take it all away
I don't feel it anymore
Oh take it all away

"Derek," Stiles whimpered approaching the older man.

"I was starting to think Stiles, I really thought that you were the one."

"What do you mean, were, Derek, what are you saying."

"I thought you were my Mate, the one I was going to be spending forever with."

"Derek, I am!"

Derek let out another growl this time shocking the both of them. He rammed Stiles into the wall behind them, his fist nearly missing the teens head as it connected with the wall. Stiles let out a small cry and Derek he let him go, fist clenched at his side.

We'll fall just like stars being hung by only string
Everything, everything, here is gone

"Not anymore." Derek whimpered as he walked away.

"But Derek, it didn't mean anything!" Stiles cried out.

"Doesn't matter"

No map can direct how to ever make it home
We're alone, we're alone, we're alone

"Der," Stiles whimpered out.

"You still don't have the privilege to call me that"

"Derek-"

"I'm going out for a smoke, you know the habit you helped me kick."

Stiles nodded. "Yeah"

"I kept my word Stiles, I kept a packet but I never touched it, I guess I have reason too."

"This doesn't have to be a reason for you to"

"I have every reason to, I need this pain to go away, and Stiles, I always came to you to help take it away"

Stiles didn't say anything as he watched Derek grab his keys and stuffing his jacket pockets with a lighter and a packet of cigarettes. "You know what I can't shake is the fact that I still love you but this time I don't think you can take away my pain."

"I still love you Derek, I do"

Derek ignored the comment. "I don't think you'll be able to make it go away Stiles because this time you were the one who caused it."

Oh take it all away
I don't feel it anymore
Oh take it all away
