Summary
“You’ve been a pain in my ass ever since you were transferred to my garrison,” Castiel snapped, dark wings flicking as his temper flared. “What did you expect when you pulled off that stunt? A congratulations? Praise? For me to tell you that I’m proud of you?”
He expected more of Dean’s infuriating defiance, so he was shocked when the other angel ducked his head instead, freckled cheekbones tinging a delicate pink. Castiel stared as Dean looked away, bronze wings curving in tight to his back, an uncharacteristic show of vulnerability.
…Oh.
Oh.
“You do want that. You acted out for attention. For my attention.” Castiel stared at Dean with eyes that were wide with surprise, but Dean merely looked at the ground. His silence was as damning as any answer he could have given, and Castiel felt the surprise in him begin to change, morphing into something deeper and more heated. “Well,” he said darkly, “you certainly have it now.”

Go hunting. Obviously.

Time and space are funny, funny things. Everything that has happened and will ever happen does so at once, both repeating in perpetuity and at the same time never existing at all.
Even Fallen, Castiel understands that.Or, the one where endverse!Castiel stumbles upon Demon!Dean, and the result is exactly as dirty and blasphemous as one would imagine it to be.

"Condoms?" He asks Kevin again because he has to be sure. "They want me to use a condom as a tactic."
"A re-rewrapped XL Condom," Kevin admits glumly. He's the best assistant Deans had in years, and he's smarter than half the guys upstairs, it's in moments like this when it really shows. "Our superiors know that you use as little restraints as possible when it comes to your interviewees. They figured if you drop a medium-sized pack on a guy and he opens it to see how large it is he'll be more likely to defect."

Summary
Set on the episode where they summoned Raphael on Earth.
“Well, last night on Earth. What are your plans?” Dean asks.
Castiel looks at him thoughtfully, his eyes devoid of any worldly wants. The angel ignores him for a few beats, assuming that the question was rhetorical. The hunter doesn’t stop staring, however. His eyes trace the angel’s vessel, currently hunched over on the seat, moonlight draping him like a false halo. Almost reminiscent to the day they first met.
“I just thought I’d sit here, quietly.”
Dean furrows his eyebrows at that. The angel has recently risen from the dead, brought back by his ‘father’, whoever that is. Surely, he’d treasure his second chance a bit more than this, right?
“Come on, anything? Food, movies, booze?” Dean asks, and then for good measure, adds another. “Omegas?”
