"Thank God, Cas, I thought..." said Dean, helping the groaning angel to his feet. "Well, whatever. That was fantastic, and brave, and damn stupid, but I'm alive 'cause of you and I guess I owe you the biggest 'gracias' in this whole messed-up world."
"It was failed attempt. I cannot accept-"
"Nah, dude" Dean paused and looked at his shoes, wiggling his fingers and chewing imaginary gum "...you saved me, okay? Don't act like it was nothing, 'cause you near got killed too. I just returned the favor, that's all."
Cas grunted, noncommittally. Dean clapped Cas' shoulder, smiling tiredly. The angel flinched.
"I suppose. Still, that could have gone better."
"True, man, but we still got all our limbs and what's better, our mouths. I am hungrier than a rugaru in a mall on Black Friday."
"Food sounds...rather intriguing."
"That's better, Cas! We gotta fatten you up, can't have you bein' too scrawny!" The unlikely pair trudged back toward the Impala, waiting in the shadows of the old factory. As he slid into the driver's seat, Dean sighed. "Guess we gotta go pick up Samantha, wherever he's gotten himself off to."
"I'll get him." stated Cas, and disappeared.
"You don't have to- dammit." Dean sighed. Cas seemed distant- more so than his usual angel-ness. Dean suspected he was still embarrassed about the...events that had just transpired. And Dean definitely didn't know how to fix that. This was all wrong. Cas seemed stuck on the edge of some border, oscillating between human and angel, the two beings merging and splitting constantly in some odd way that definitely couldn't be healthy, and probably couldn't maintain for long.
