An Angel's Grace (A Castiel X OC story) (Supernatural.)

Road Trip

Road trip.

"Dean!" Dean looked up from packing his bag, seeing Grace and Castiel, he let a small smile through as his sister came to hug him.

"Hey, Gracie." He held her tight, kissing her head afraid if he let go she'd vanish, Glancing back up at Castiel he gave a slight nod. "Cas. Now, look at you, all suited up and back in the game.

"I, Um...I cam as soon as you Called. I wa—" The angel looked around, seeing how trashed the room was as Dean finally let go of Grace who moved to stand off to the side.

"Dean, what happened? What's wrong?"

"Is it because of Kevin?" Dean turned to look at her, "You know? How?" Dean's voice was terse, Grace flinched away from him, "I, Uh...I had this dream...about Kevin, and Gadreel..." his anger only intensified as he stared her down, she moved to hide behind Castiel.

"Sammy was Dying. What was I supposed to do?"

"You let an angel possess him?"

"It's more complicated than that, Cas. He said it was the only way, and we both believed him."

"Now Sam's gone. Kevin's..."

"I'm sorry. "

"Yeah, well...Sorry don't pay the bills, does it? It sure as hell ain't gonna bring Kevin back. We gotta find that son of a bitch" Grace watched her older brother warily.

"Dean..."

"That Angel is a Dead man walking."

"What, you're gonna destroy him?"

"Damn right." Grace leaned back in her chair

"Dean, if you kill an angel, it's vessel dies, too. That means you'd be killing Sam..." Dean turned on her and she instantly shut up.

"You think I don't know that?!" he snapped bac at her, Castiel frowned, "Don't scream at her, she's only trying to help, Dean."

"If I don't end Sam and that halo burns him out and I...God, I was so damn stupid."

"You were stupid for the right reasons." Castiel tried his best to comfort his friend,

"We both were...you agreed to it, Dean, but Me...I was the one who tricked him, I let Gadreel use me..." Castiel looked both surprised and angry with this new news, she knew they'd be talking about this later.

"Yeah, like that matters."

"It does. Sometimes that's all that matters. Listen to me. Sam is strong. If he knew an angel was possessing him, he could fight."

"He could cast the Gadreel out?" there was a hopefulness in the young Winchesters eyes, 'Maybe. But as far as I know, he's in the dark. I don't know how we clue him in."

"Do you remember Alfie?"

"That kid angel? Yeah. Why?"

"Before he died, he told me the demons were able to dig into his mind, access his coding. We might be able to do that here. Might be able to—to bypass the angel and talk directly to Sam."

"And you think that would work?"

"It's worth a shot, this bastard killed Kevin." Both Dean and Castiel glanced at Grace who's fists were clenched, "Uh, okay. Um, where do we start?"

--

"Hello, Boys...and girl? I don't believe we are acquainted, Name's Crowley." Grace raised an eyebrow at the demon, she'd heard of him through conversations between Sam, Dean and Castiel but she'd never met the man...er, demon.
