Something really, really quick I wrote up in creative writing class. Miss Elucidation and I wanted to do a small Destiel prompt in the beginning of class just for fun, and this is what I wrote in ten minutes. I know, it's nothing special or especially interesting, but I felt like uploading it. Maybe one day I'll go back and expand on this.
Castiel folded his wings across his back and perched stoically on the roof of an old house across from the gas station where a black Chevy Impala rested. Sam and Dean Winchester refueled and inspected the car for any damage sustained from their last hunt as the angel watched from his post, invisible and silently hidden from the humans below. His icy blue eyes followed the younger brother into the motel a few blocks off, making sure Dean would be left alone for at least a few minutes.
Dean turned back to the Impala after returning the pump back on its rack, jumping at the sight of Castiel blocking the driver's seat. He immediately pointed a finger at him and spoke accusingly.
"You're a real douchebag, you know that?"
Castiel winced. "I… apologize."
Dean huffed, clearly more than a little annoyed with the angel. "Don't give me that crap. What happened to 'I give you my word?'" He ran his hands through his spiky dark hair, brow furrowed in frustration and disappointment. A truck drove past behind them on the freeway, clearly speeding and honking loudly. The neon lights glowing from the signs in the window of the station store reflected off the waxed surface of the Impala as they stood face to face in silence.
"Look, we can't talk here. Sam's getting us a room, can you try to show up later?" Castiel's face showed no guilt, but he suppressed the hurt he felt at that last statement. "Don't look at me like I just slapped you Cas, I have a right to be pissed."
It was true, Castiel had not kept his promise to help the brothers when they needed it these last few months, but he was in the midst of a civil war between his own siblings. He couldn't afford to operate according to Sam and Dean's schedule. He had priorities, as much as he wished he didn't.
"Of course, Dean." His body disappeared from Dean's sight, leaving him alone with the car and aching remorse at the empty gas station.
