Dean was drunk. He usually was, now that there was nothing holding him sober. Castiel was gone, Sam was in the Pit, Lisa and Ben were gone, and Bobby hadn't contacted him for over 6 months. What was to stop him from drinking himself to death now? Cas... That feather-winged bastard had flown off after Dean gave him a drunken confession 3 months ago. I love you, Cas. The words were slurred together, hardly comprehensible, yet Cas hadn't bothered to stay and figure out if he meant it or not. Nooooo, see, that coward with a halo had to go on and freakin' fly off like the scardy-angel he was.
Dean was in the bathroom, washing his jacket in the sink. Frustration built within him while he scrubbed. Unfortunately, the anger also made him sober. Stupid son of a bitch. Can't even bother to show up during a hunt. Got my ass handed to me by a couple of demons! Can't believe that flaky son of a bitch... Should've known better than to fall for a damn angel in the freakin' first place. Stupid stupid stupid, He thought agitatedly.
Out of habit he looked up into the mirror and jumped. "Damn it, Cas. Don't do that!"
"My apologies. Dean-"
"Don't, Castiel. Just don't. You don't have to explain. Me and my big mouth get the picture, okay? Don't make this worse than it already is." No, please. Explain. Tell me why you left. Tell me why I had nightmares and woke up screaming your names for weeks after you left. Tell me you're sorry and that you've fallen for me. Please don't listen to me. Don't take my orders with a smile for once in your over-obedient life. Please? But Dean doesn't say that. He bites his lip, and waits for a reply.
"I... As you wish." You stupid coward, Dean thinks. "I came because I wanted to let you know that I've decided to go back home. To Heaven. I have not seen my brothers since Lucifer," You mean Sam. Say Sam you piece of crap. "Was thrown into his cage. I miss them." Yeah right. You're just waiting to get the hell out of dodge because you know just how pissed I am at you. Cas, at least, has the decency to look apologetic in his eyes. But that's not what Dean wants to hear at all. It's not what he cares about. It's the wrong order of the words he wants.
He gives a hollow laugh and shakes his head. Cas gives his signature head-tilt in confusion. "Nothing, I just find it hard to believe that we came all this way together and you're just gonna ditch town and leave to be God's bitch again." Castiel stared at him. "I miss my brothers, Dean. You of all humans should understand the longing sensation I feel." You're seriously bringing up Sam right now? You and your stupid wings that aren't even on this plane are bringing up the only family I have and can't save right now? Fuck off!! But Dean keeps his mouth shut. He turns his back to the Angel of the Lord, and walks out of the bathroom, toward the door. He's very near shaking with anger. He pauses with his hand on the doorknob.
"I knew you didn't care about humans. It was all part of your elaborate plan to screw with me. Well, that's fine with me. Don't let the door hit ya on the way out, you rotten piece of crap." He mutters, knowing the angel will hear him perfectly.
"Dean." Castiel's voice is feet from his, gravely and low, rumbly in his chest. It's all Dean can do not to punch him in the face and shatter his hand again. "What?" He demands without turning around.
His shoulder is grasped firmly and yanked backward, spinning him around. His lips are crushed with Castiel's in a desperate kiss. It isn't perfect. It's scary, rough, harsh, desperate, but then again, so is the life of a hunter. Dean has no idea what the hell all of this is, what all of it means. His mind isn't working properly, filled to the brim with Castiel's scent and taste. He can't breathe. Doesn't want to. Doesn't want this to end. Right when he thinks this could go on forever, Castiel breaks away, leaning his head on Dean's for a moment to catch the breath he doesn't need.
"Goodbye, Dean." He whispers, and disappears. A tear slips through Dean's amber green eyes. And people wonder why he thinks Angels are such Dicks.
