[ "Nutcase" is a bit harsh, and Castiel's frown deepens. It's not that he's never heard himself or his family referred to in those terms, but... Dean was supposed to be different. He was supposed to understand. Castiel wonders, not for the first time since he found Dean, if maybe there was some mistake. But no, his information was thorough. He isn't looking for some Dean Winchester, he is looking for the man in front of him. The one currently pointing a gun at him. Castiel doesn't move, and Dean, strangely, hasn't gone for his car yet, either. At the question, Castiel's chin tips upwards, his eyebrows lifted, and his tone sounds stiffly rehearsed, as he tries to assure not only Dean, but himself. ]

You were chosen by God.

[ This man. This disbeliever was chosen. It's not Castiel's place to question, to wonder, but he does. Nevertheless, he explains, since Dean has done him the favor of not shooting him yet, but rather talking to him, instead. ]

Your purpose in the world is greater, higher than... all of this. All of the people you've met, and all of the cities you've been to: the Earth as you know it are beneath you. You are chosen, Dean Winchester. Transcendent. Righteous.

[ As far as Castiel is concerned, Dean doesn't need conversion. He is already purer, more sacred than himself. It's a bit disturbing, honestly, to be faced with such righteousness in the form of... larceny and pool hustling, but who is Castiel to question the work of God? ]
