The wet slap of skin hitting hardwood nearly makes Dean jump.

He'd been sitting at Bobby's kitchen table, staring blankly at the laptop screen that was supposed to be telling him of their latest case. He hadn't been paying attention to any of the words, not really, his eyes just vaguely ghosting over the blurred words.

The noise makes him turn sharply in his seat, hand already reaching for the gun tucked into the back of his jeans. He falters though when he sees what caused the noise, when he sees the prone figure curled up naked on Bobby's floor, shivering as water drips from his body.

"...Cas?"

Dean's quick to rush to his side, a hand reaching out to lightly touch the Castiel's shoulder. Theres no movement, not at first, but then Castiel flinches and Dean's pretty sure his heart practically stops. He watches as Castiel's eyes flicker open, his usually intense blue eyes looking dull and muted. They take a moment to focus, before meeting Dean's.

"Cas?" Dean asks tentatively. "...That you in there?"

Castiel slowly tries to sit up, but a grimace of pain flickers across his features and he falters, looking like he's about to slump back down again. In a moment of panic, Dean's arms go around Castiel, holding him close to his body.

"It's okay, I got ya..."

Castiel seems to relax at Dean's words but he's still shivering violently, as his flat to his forehead as he's practically soaked. His face nuzzles into Dean's chest, almost as though of its own accord, as though he's seeking warmth, and Dean knows he needs to do something before Castiel catches hypothermia; although he's pretty sure angels can't do that.

"I'll be right back, okay? I gotta get somethin' to keep you warm."

He carefully lowers Castiel back onto the floor and hastily gets to his feet, practically sprinting upstairs in an effort to find something he can wrap around Castiel. He stops in the doorway to the room he's been sleeping in - or, at least attempting to sleep in - and his gaze falls on the coat folded up at the end of the bed. He grabs it without a second thought and rushes back downstairs.

Castiel is exactly where Dean left him and the hunter wastes no time helping him get his arms into the coat. It almost looks too big for him, Castiel's lack of clothes not giving him the extra padding that he usually has when he's wearing it.

"Figured you'd want that back at some point...I kept it, y'know, just in case."

"...Thank you." Comes the quiet answer and Dean's pretty sure he can see a hint of a smile playing at the corner of Castiel's lips. He can't stop himself from smiling faintly, and he feels like he hasn't done so in years.

"Yeah, well...I ain't lettin' you go that easy."

"Dean...I..."

"I know, Cas. Sleep, okay? You gotta rest. We'll talk later."

Castiel nods and his eyes slide shut, his body giving in to the sleep that it had been so desperately craving. Dean just watches him, not daring to tear his eyes away for even a second in case this is all one big hallucation just to screw with him. He can't risk losing Castiel again, not this time.

When Bobby finds them hours later, they're both sleeping, Dean's arms wrapped tightly around Castiel's body, holding him close. He shakes his head fondly, murmuring something that sounds vaguely like 'idgits' as he leaves them to be alone.
