What possessed him to close that painfully short distance between the table and the bed, he would never know. All he knew was that the poor man he loved was fretful, even in sleep, Dean worried, feared and cared, meaning he also hurt.
"Someday, somehow I'm going to make it alright." Castiel promised, pain, love and the urge to protect the fragile human – who was tossing and turning as he cried freely – all shot through his chest. He sat on the edge of the bed and sighed.
"What have I done to you, you gorgeous man?" He whispered softly. Yes Dean was physically gorgeous, but Castiel couldn't care less about that. It was Dean's mind he loved, his obsession with classic rock, the way he would have done anything for his brother even go to hell for the guy (which he had). An angel only ever fell in love with someone who knew how to love unconditionally and to the point of foolishness. Dean took it beyond that, it was his ability to love someone beyond all their crap to the point of being insouciant, something Castiel had told the hunter more times that he'd had proper food.
"Cas." Dean whispered, still sleeping. Even in a state of unconsciousness he could feel that the angel was there. That acknowledgement was all it took for Castiel to take off his trench coat and suit jacket before climbing into bed with the man he loved. He laid on his side and wrapped his arms around the hunter, his hunter, he felt peaceful for the first time since Dean had left.
"I love you Dean Winchester and I will never hurt you, not again." Castiel promised first in English before repeating it exactly in Enochian.
"Love you too Cas." Dean murmured snuggling closer to the angel who held him, chasing away the nightmares. Now if it had been anyone else, he wouldn't even have had the motion to snuggle, but because it was Castiel, his Cas, the one who had saved him so many times on hunts or from hell, but most Castiel had saved Dean from himself, because it was the one who held his heart, it was instinctual and he loved to be close to warm heart inside his lovers chest. The sound of his heartbeat was like a lullaby to a child, it kept him safe at night, helped him sleep soundly, but more than that it told Dean that his happiness wasn't a dream and he deserved to be happy. After all the pain, loss, disappointment and despair he'd suffered, Castiel chased all that away and his warmth filled even the coldest and frozen parts of his heart and soul, he felt when he was with him. Dean may well have taught the holy tax accountant how to be human, but he had also taught Dean about being human too. There was no teach-student thing between them, only mutual learning.
A/N: I heard the lyrics to Nickelback's Someday while I was writing this out and they seemed to fit so I put it in. It's only going to be a short fic, so another couple of chapters and it will be done :)
