He's not trying to be cruel, really he's not, he just ... how can Dean not know? He sighs exhausted and runs a hand through his long hair, scratching his scalp.

"Well, if he doesn't know then you and he are the only ones that don't." He shakes his head and just ... it's his instinct to want to look after Dean, and try and help him through his emotional ... whatever - but at the same time it's not really his place to spell this shit out for Dean. "He wants the same thing you do."

He can't force his brother to do anything about it if he insists on being stubborn, but he's done what he can short of locking them in their together, which as tempting as it is would probably turn out to be a bad idea in the long run.

"Whatever you say, Dean. Look, you don't have to figure it out with me. It's him you've got to talk to. Just don't be a stubborn ass." He claps his brother once on the arm, gives him a supportive smile and then steps back.

"I'll be in my room."

Sam feels like crap, but he doesn't need to be fussed over the way that Dean wants to. He's half convinced that Dean's doing it at least in part to avoid dealing with his own shit. "I'm fine Dean. I can make it to my room by myself. Go deal with your angel."

He brushes him off, gently but firmly and then heads back the way they came out of sight.

"Dean," his voice sounds exhausted, as if Dean is missing a very obvious point. "I'm not suggesting this as a permanent solution. You said that I can't guarantee that I will stay, this way I can. I can't fall back on Naomi's programming and neither can she take me. I am doing this willingly, I want to be here. This is where I want to be."

He thinks about arguing and thinks about earlier and then the fight goes out of him. His stomach twists unhappily and gives his wrists over but turns his eyes away from Dean to look past him at the wall opposite. "You won't even let me try, will you?" He doesn't mean it to come out as sulky as it does but really Castiel is at the end of his patience. He can't take another year of this, he feels like he can't take another day.

He's not reading Dean's mind, but what he says puts the pieces together well enough. "I meant you're not going to let me try everything I can to fix this. I can't give you the security that I won't leave if I can't give you some kind of guarantee. I thought this could be it. It was all I could think of."

He hasn't even been down there an hour but already his wrist is sore and a little stiff from the tight cold metal. "Dean."

"Dean you don't have to ... " he huffs unhappily and looks away. "Don't bother Sam. I didn't do this to get your attention or impose my company on you. You don't have to put your brother between us. I know you're uncomfortable around me. You've made that abundantly clear."

It hurt, but seeing Dean use his brother as a buffer hurt more and he'd rather Dean push him away once outright than patronise him and made Sam play babysitter to them both.

"Then what are you doing? You don't have to babysit me." He stands up when Dean starts pulling but he stays standing in the same spot, digging his heels in, going nowhere. "I won't put you out of your bed just because you didn't like my solution. This is completely unnecessary."

He gives up. Dean wants him out of the dungeon, fine. He'll go. There's absolutely no sense in arguing it because Dean is just going to keep badgering him to go. And when the angels find a way to take him or they get separated again it will be all on Castiel once more and he can't stand the thought of it but figures he might as well get used to it. It is inevitable.

His face hardens a bit in anger and he stares intensely at the other man, before finally moving forward, storming past him and heading for the door. He doesn't know where he's going yet, just not here.

Castiel isn't really thinking about what he's doing at this point, he's just angry, and hurt, and a thousand other things that he really doesn't know what to do with. And they need an outlet but there isn't one. Dean wants him to stay so he tries, but then he wants him to leave the dungeon so he does, and now he's following him with some other set of needs and or desires and Castiel just needs to get away as far and fast as he can. There's nothing for that either because he's injured and Dean isn't and he's gaining on him.

"You are the most infuriating person I've ever met!" He says it in a loud frustrated roar, spinning around and deciding without really thinking about it that since he can't have space he'll take the opposite. He strides forward meeting Dean halfway and grabs hold of his shirt, backing him up into a wall not far from the door. He does it with all the force he had used in the alleyway so long ago, but instead of throwing a punch instead he meets Dean's face with his own. He kisses him long and hard and possessive and demanding. It's not remotely nice or sweet, all anger, and sadness, and fear and desperate need.

He finds himself needing air just as badly as Dean does and isn't that a bitch? He pulls back, but not far enough to let go, just enough so that he and Dean both can get some air into their lungs. His heart is pounding and the world is spinning a bit. He hadn't meant to do that, really he hadn't. It had been a knee-jerk response (since when did he have those either?) to release the storm of emotion he'd been feeling.

Of course that didn't mean that he didn't mean it.

"I'm fairly sure the appropriate term is still 'kissing'."

Why? It should be so obvious. Castiel removes his hands from where they've balled in Dean's shirt and bring them up to hold his face. It's not gentle like caress ,it's firm and insistent, making Dean look at him, making him meet his eyes.

"Because I keep trying to make you proud, because I keep trying to stay with you and I always fail at both. Because I can't do another year of being at odds with you like this. It's too much for me to take and I can't stand having you look at me the way you do when you're disappointed or hurt. Because I need you to know that I need you too and that you are precious to me, as a friend, as a brother in arms, as the person that I--"

He stops there and just stares at Dean a moment, uncertain if he should continue. Yes, Dean kissed him back but that doesn't mean that Dean isn't apt to reject this gesture.
