"Cas, I've been enrolling me and Sammy in schools since I was twelve. I think I can handle it." Cas is frowning. "It's not a matter of--handling it," he says. "The principal will be more receptive and helpful to you if she believes you to have a parent or guardian who is actively concerned with your welfare. I want to make sure she understands you are important." Dean does not get a warm squishy feeling in his chest.

“The fuck…?” he grumbles to himself, pulling the carafe of hot coffee out of its holder with his right hand and steadying his mug on the counter with his left. He looks down into the mug and yelps, surprised to see something white and wriggling at the bottom of his cup.
“What the fuck!” he yells, spilling hot coffee all over the counter, when the wriggling shape resolves itself into something resembling a miniscule white snake.
With wings.
There was… there was a goddamn dragon is his fucking coffee cup.
After a run-in with a rogue Woman of Letters, Castiel finds himself with visible wings.

There’s conflict in heaven. Michael is arguing that the children of earth are too favored by their father. That they have done nothing but cause war and strife, practically destroying the world God had carefully crafted for them. Another faction argues that mankind is still young. Yes, they are brash, but they will learn. There are signs of goodness that sprout up all around them. Michael argues these are tangible things only - too easy to destroy with the darkness that lies in every man. It is decided an emissary will be chosen to go down to earth. They must find some proof that humanity has good in it. Castiel is sent on a mission to find this proof. What he finds instead might end up being so much more.

Set in S5 after 5x03. Dean wakes up in an alternate universe, only to find that he's stuck in (Sam's) terrible life. Only this time, it's courtesy of Lucifer, not Zachariah, and Dean (and Cas) are aware of what's going on, though Sam's clueless. As they try to find a way to help Sam learn his "lesson," or whatever, Dean realizes that things in Zachariah's version of this warped reality weren't as simple as he thought. Cas was there too, apparently, though Dean doesn't remember it, and he has a feeling there's something else that Cas isn't telling him.
An argument with Dean spurs a recently fallen Cas to prove he can be useful as a human by finding his own hunt. But when he’s taken by the unknown creature he’s hunting, Sam and Dean have to race to his rescue. Only it turns out this monster feeds on secrets, and the secrets Cas has been keeping may be too deeply hidden for him to be saved.
Cas lets his feelings run away with him, Gabe is a total dick, Sam is concerned, and Dean has to make a choice. Gabe forces them to bond, technically….

Castiel isn’t talking, so Dean and Sam are left to figure out who took their angel’s wings and why. When they finally do figure it out, the truth gives Dean the courage to finally tell Cas how he feels.
