A/N: Hey guys! Another story YAY! So this is going to potentially be a chapter story if I get some reviews from you lovely people! Please read and review, loves!

Cas.
Dean couldn't understand it. Sure Cas had disappeared before and Dean had been worried but this time Dean hadn't slept. Wasn't sleeping. Cas had said he would only be gone for three hours tops but it had been three days. Dean had paced. He had eaten. He had watched porn. Hell, he helped Sam research. Just looking for something to get Cas off his mind. None of it helped. (Certainly not the porn. That just made things worse, to Dean's surprise.) Sam had tried to get Dean to do things to; like leave the hotel. Or sleep. But for some reason sleep was the one thing Dean couldn't manage. He didn't know if he could handle not being awake when Cas got back.

So that's why he was surprised when as soon as Cas got back the first thing he did was put Dean to sleep.

****************
Dean groaned as he woke up, sitting up quickly as soon as he remembered what happened. Seeing the trenchcoat wearing angel sitting at the table reading Dean got up and sat next to him.

"What the hell Cas? Why did you make me go to sleep?" Dean knew he was being harsh and loud but the angel had left him for three days.

"Dean. You forget that I can hear your thoughts and prayers. You needed sleep. You also need to trust me." Dean looked over, shocked at the angry tone to Cas's voice. Cas looked back, the anger not just in his voice but in his eyes. Dean opens his mouth to say something but Cas beats him to it.

"Dean. I can not stay for long. I am being- requested somewhere else. I have not much time but I am here to say goodbye." As Cas spoke the anger dissapated from his voice replaced by his typical gravely monotone.

"Wh-at? Cas what are you talking about? What do you mean requested? Somewhere else? What the hell?" Dean's mind was spiraling and it was going no where good. Dean was losing someone. Again. And again it seemed he couldn't do anything about it.

"I do not believe that I can answer all those questions at once, Dean. I can only only tell you this. You and Sam will not be alone. I just won't be here. But like I said Dean," laying his hand on Dean's shoulder, "You have to trust me."

Dean would have continued argueing if it werent for the look in Cas's eyes. He was scared. This was the first time Dean had ever seen Cas look scared and if fucking terrified Dean. Feeling the hand on his shoulder tighten Dean brought his own hand to lay on Cas's.

"Cas man. If you need help..." He was cut off again by the angel but this time not by words but by his lips. Dean shocked didn't have a chance to react before it was over.

And when Dean opened his eyes Cas was gone. And the unusual smell of smoke seemed to prove that it wasn't by Cas's own free will.

Cas had said goodbye. But Dean hadn't and he wasn't going to. Not yet.
