Grey|| Valyria (derpderpdestiel; sassary-quinto on tumblr)
Summary: When Castiel raised Dean Winchester from the Pit, he inadvertently claimed him as his mate.
Ten thousand days later, the angel Castiel lays his hands upon Dean.
He looks up and sees blue.
He thinks of his brother for the first time in a decade. “Like the sky Dean. Blue like the sky.”
Around him the shadows of the pit are suddenly black and white and red.
His blade falls forgotten from his hand.
A shining angel pulls him into his arms.
This fic is really, really lovely and perhaps the best with a/b/o dynamics I’ve ever read. You’re going to hurt when you read it, but it’s so, so worth it. The style is really beautiful and the story so very touching. Highly recommended!
