Summary
"Am I the big spoon or the little spoon?"
Dean wants to roll his eyes, but decides it's better not to. "What the hell, Cas? What are you talking about?"
"Well," he starts, even-toned, as he continues to undress slowly before Dean's eyes, "Sam asked me earlier if I was the big spoon or the little spoon."

Summary
When Dean Winchester’s friend and neighbor, Garth, moves out of their duplex, he is not expecting him to be replaced with a cranky, weed-smoking recluse with zero taste in music, but that’s what he gets. But Dean soon realizes there is more behind Castiel’s brooding stare and prickly personality. There is someone worth getting to know. Someone who needs a little TLC, even if he is too stubborn to admit it.
Castiel Novak is a survivor. He has survived his parents' tragic death, He has survived being kidnapped and tortured by his own brother, and he has survived living with the constant flow of nightmares that have followed. So Castiel can certainly survive having to live next to an annoyingly cheerful (beautiful) man, with kind green eyes and an unhealthy affinity to classic rock, who is determined to be his new friend.
Or, the one where Castiel starts a friends with benefits relationship with his new neighbor, and finally starts to heal his heart.

Summary
Dean’s voice is all low and husky and “you didn’t do so hot on your exam, Cas,” he says.
And Oh god, Sam thinks, and brings his hands up, runs them over his face in his nervousness, through his hair, and what’s it going to be like, he thinks, when he shatters Dean’s world—now, a life so simple where the only worry is Cas failing his laundry test, and then, The After, when Sam’s told Dean that Cas is...
Dean and Cas have a very public deathbed confession and officially become an item. And this would totally be thrilling—except Sam gets knocked out during the fight and misses the whole damn thing.
Or the one where everybody except Sam knows and Sam thinks Dean’s sudden newfound celibacy is a witch’s curse.
