Number One: Dean would definitely never appear on a soap opera. Number Two: Dean Winchester did not wear makeup. And Number Three: He was not gay! God, Cas, whoever was listening - Please get them the hell out of here. (Set around the French Mistake.)

Cas feels it - the minute Dean is ripped into anguish, and he feels it. Season 9x09 Coda. Oneshot.

Dean hated the fact that his parents didn't trust him. He didn't need a goddamn babysitter. He could look after himself, and his little brother, for the whole of one little night. What were they afraid of? That he'd burn the house to the ground? - Destiel AU

Dean receives a phone call that elicits a response he's not so eager to repeat - seriously a panic attack? Him? Cas is in the hospital and his condition is critical. Dean and Sam spent the entire night on the road towards Idaho - everything just seemed to fall into place after that. Destiel/Oneshot

It had been a good old fashioned hunt, topped off with memories Dean hadn't paid mind to in years, mixed with some feelings he'd rather forget. It had been home once, for a short time. But it had no comparison to this, the bat cave, his family, all completed by the feeling of being wrapped safely in Cas' arms. Episode 9x07 Coda.

Nothing seemed overly different after Dean downed the concoction that he and his brother had spent the last hour preparing. He'd expected maybe a few more flashing lights of emphasis, maybe at least a distortion to his senses, but he still felt completely normal. This felt like nothi – OH my God was that a ball! S9 Episode05.

In Purgatory Castiel understood. Dean needed release and Cas was the only one who could provide it. Now, back topside, it's no longer making sense. Dean could turn anywhere to gain what he is seeking; so why is it that he keeps turning back to him? Season 8, OneShot.

Castiel: All powerful Angel of the Lord. Soldier of Heaven. Warrior of free will... Itty bitty little body. Those friggin' witches are at it again.
