[Castiel... doesn't move, not really. He lets River swings their hands, lets her move. Occasionally, he turns a little with her so they're still facing one another even as she keeps swaying. What an odd girl, and so in love with her own slow sway. Castiel doesn't understand it, any of it, but... she enjoys it. And just like he can't help but smile back when Dean laughs, he can't help but indulge River. They're his charges, after all.]

I have not reached the end of that story. Dean told me about it. The world is saved. We lose each other. I destroy everything.

[Castiel doesn't sound broken about it, because no matter how much he fears this reality, it is still only a story to him. He can hardly understand his feelings of the present - how can he know what to feel about the future? He won't find his Father, but he will help save the world. They will lose Sam, but Dean will survive. They will split up, but at least for a while, Dean will be happy. There will be war, but... There will be war. And it is his fault.]
