I love this. I expected it to be more cracky from the notes, but I'm happy it wasn't. It was funny because you seem to have an amazing sense of humour, and this wasn't the first angel marriage fic I've read, but probably my favourite so far.
And can I just say that your gruff, fierce, freaking-wearing-Dean's-clothes version of Cas is terrifyingly hot?
I liked the character portrayal in general, and also their dialogue and lines, the small sub-plots, everything really :3
(Also, if anybody ever catches me naked somewhere, I will totally say "Be grateful I'm wearing a vessel". Seriously.)
