Disclaimer: Once again I do not own Supernatural or Sugar, were going down. Nor do I own The Black Wings of Apocalypse (on a side note It's a rap song and the lyrics really have nothing to do with the story...I just liked it for the title.) This is actually going to be two parts once I figure out where I'm going with it.
The shadows on the wall only prove one thing to Dean, Castiel has huge wings. The firs time he see's them they symbolize Castiel The Angel of the Lords power and place. And Dean would be lying out of his ass if he said they weren't intimidating. They span the back of the barn in black shadow. He doesn't know what to think. Raised as a hunter and never hearing a single peep about the celestial beings above, not that he would have believed it till he saw it anyway.
The second time Dean see's the masses of black shadow, he is just in awe. Don't get him wrong they are still intimidating but less so since he has became familiar with Cas. He's not entirely sure that Cas knows that they are out. He has time to just glance before another black-eyed bitch reaches for his neck and Cas is right behind her ready to smite wings out.
Since then Cas' wings have been a constant thought pushing in the back of Deans mind. He wonders often what they look like, what color they are because, he has a sneaky suspicion that they are not white like what is depicted in most angel lore.
He stops wondering at some point between Lucifer rising and the present. So when Castiel comes stumbling into the motel in a slight flutter of wings Dean doesn't have time to properly look before rushing to catch Cas under the armpits before he falls to the ground.
He is to busy panicking because Cas looks like he is in some serious pain. "Cas...cas..cas" is all he gets out before Castiel slumps against him out cold. He stumble to the bed to lay Cas down, and then looks and notices the massive wings black with a blue sheen the color of Castiel's eyes. To say he was in awe would be an understatement. He goes to turn Cas onto his stomach because he's not entirely sure what else to do.
That's when he noticed the seeping red blood, and missing feathers on the back of Cas's limp right wing. Shit. He thinks digging into to his pocket to get his phone. He presses speed dial #2 and Sam picks up on the second ring. "Hello". "Sam, get your ass back here." He hangs up after he hears Sam say okay. He tosses the phone on the other bed and kneels down close to were Castiel's face is.
"Cas...can you hear me?" he asks. Castiel doesn't answer so he reaches out to brush Cas's arm. "Cas, come on man I need to coherent." he says as he hears the impala pull into the motel lot. And then Sam's in the room. "Dean..what the hell happened" he asks seeing Castiel face first on the bed with slashes in the back of his trench coat. "I don't know Sammy he just showed up here...passed out..what the fuck am I supposed to do with bloody wings?" he asks standing to look at Sam.
"Wings?" Sam asks making bitch-face number #5. "Yes, Sam these huge black things covering half the bed" he answers slightly confused. "Dean, I don't see any wings." Sam says kneeling down where Dean was before reaching out an hand towards Castiel's back. "Don't" Dean yells smacking his hand away. "We need help, call Bobby." He says pushing Sam away and reaching to try to wake Cas again.
