Since you're gone my empty arms have nothing left to hold

Ooh, this is lovely! You've got such a perfect hold on Dean - he's trying to get control of his issues, and he's doing the best he can, but nothing is easy for him... including relying on Castiel. I'm very glad you had Cas veto the blood-drinking. Dean is convincing as being at the point where he'd contemplate it, and that's interesting, but the premise that it would actually work (or work well) is a good one to see rejected, I think. And as for the wings and the glory... oh, my goodness. Incredible. Absolutely incredible. And yay for wing!fic that keeps in mind that the angels' wings function like birds' wings (locomotion and wrapping) rather than a prehensile way like bats' - why else would they take on an appearance with hands, for goodness' sake? (Erm... I am quite possibly the only person in the entire world who thinks like that, aren't I?) Point is: wonderful fic; so many thanks for sharing it.
