This was his fault. It was all his fault. Why did everyone close to him have to die. Why did everyone he cared about die. Why couldn't he stop any of this. It wasn't fair anymore. He needed something to be right for once, to be okay. And there it was. A hand on his shoulder, someone was there and he didn't have to look to know who it was. He could smell him he could feel him.
He watched his sister go to his dead beta and Stiles came to him. This is what he needed, someone to care about how much this hurt. Someone to understand and be there. He didn't know who or what he had expected but he knew now that Stiles was who he needed. Stiles seemed to be that one thing in his life that hadn't gone wrong. No matter what happened Stiles was like that immovable object.
Stiles lightly squeezed his shoulder, letting him know that it was okay to hurt. That he was there for him and always would be. That if sitting in silence made it hurt less he would be willing to do that. If he needed to cry his eyes out he would be there to hold him.
Derek slowly turned, his gaze finally able to leave Boyd and Cora, passing over Isaac, Jennifer and Lydia and going to Stiles. The teen was looking down at him in a look of concern. He was really worried about Derek, about how he was handling this, about how much it was hurting him. Stiles really, honestly cared. He never had to question whether Stiles cared or whether Stiles would be there. Because he always did care and he always was there.
Derek slowly got to his feet, Stiles hand started to slide from Derek's shoulder though it was as though he wasn't sure if he should let it fall or keep it there. However a moment later Derek was in his arms and really crying into his shoulder. Stiles was shocked for a moment before he slowly put his arms around Derek and felt the alpha almost relax in his hold, which made Stiles seem more comfortable holding him close and rubbing his back a little.
They stood there for the longest time before Derek whispered to Stiles, just barely able to speak the words right into his ear.
"Stay" it almost sounded like a question but the way his voice shook and broke with that simple word he knew it was more of a plea.
"For as long as you need" Stiles replied in a quiet and just as pained voice. He felt Derek relax more against him like he was thankful the teen was willing to stay. To stay and keep him together when he was surely falling apart.
