He was almost in the car, angrily ridiculing himself for his obvious lapse in sanity when he was grabbed from behind, spun around, and shoved roughly against the side of his impala. He had been so caught up in his thoughts, he hadn't even heard the tale-tale 'fwoosh' of feathers that signaled Cas had appeared.

The angel was now pinning him against the car, his face still flushed from earlier, and his eyes blazing. His wings were flared out behind him, dominating the space around him, and baring down on Dean.

Dean audibly swallowed, his eyes glued to Cas' crystal blue ones.

"How are you seeing them!" He pressed harder, causing his entire body to press flush against Dean's. "How are you touching them?" He was shaking...with fear or fury, Dean wasn't sure. He reached up to clasp the angel's wrists.

"Cas, calm down." He was getting worried. The angel NEVER lost his composure unless something was really wrong…and to see Cas this flustered and this furious, then it had to be one hell of a something wrong. He tugged at Cas' arms to try and lessen his grip, but his fists would not budge.

"Cas, dude, you're freakin' me o—"

"HOW!"

"I DON'T KNOW!" he hadn't meant to scream so loud, but he was on edge as well, and Cas' hard, almost accusing gaze, did not help.

"There has to be something…" he hissed between his gritted teeth.

"No-nothing, I swear." Dean's brow furrowed as he watched Cas. The sudden and inexplicable fury that seemed to emanate from the small angel, seemed to slowly dissipate as he watched…still his fists stay clenched in Dean's jacket. "Cas, what's wrong?"

He was answered with only a frown and a shove as Castiel pushed off of him and stepped away, putting a couple feet between them. "You should not be able to touch them." The frown stayed and his wings shook. He drew them in close to his body, as though he was trying to hide them.

Dean was happy not being pinned anymore, but he suddenly realized how much he missed the angel's warmth. "There's gotta be a logical reason, Cas. Or maybe even a non-logical one." Dean rubbed the back of his neck, looking away from the intense stare Cas was throwing at him. "I'd take that one right about now."

"Dean, this is serious."

"You don't think I know that?"

"I don't think you realize what this can mean."

"It means I can see your feathers…" Dean rolled his eyes. "What I want to know is why." Castiel gave him a tilted head and an impatient glare.

"Obviously, you enjoy making light of a very important issue."

"Jeez Cas, I don't think the world will end!" Dean stepped forward, grasping his shoulders, feeling the muscles tighten under the bulky trench coat. The wings shivered and Dean found himself looking over Cas' shoulder at them. "They're amazing, Cas." Castiel blinked, and to Dean's surprise, flushed and averted his gaze.

"Do not distract me Dean." He looked back up, blush still present on his cheeks, but lips set in a determined line. "I must find out what's going on."

"Maybe it's just a freak accident?"

Cas shook his head. "This is not something that just happens. There is a reason."

Dean suddenly frowned, his grip tightening on Cas' shoulders. "I'm not dying am I?" Cas blinked in confusion. "I mean, I don't have like stage four cancer-of-the-something-freakin-obscure that we've just happened to overlook huh?"

Cas seemed to actually ponder this for a moment, staring so intently, that Dean was sure the angel was actually looking for the cancer inside his body.

"I do not think that would be something that could sneak up on us."

"Then I think it's not something to worry about." Dean waved his hand dismissively, as though trying to wave the issue away from both him and Cas, still leaving one hand touching Cas' bony shoulder. "Maybe it's just that profound bond you keep going on about."

The flush that made it's way up Castiel's neck and to the tips of his ears was only slightly more surprising than the fact that Cas was suddenly avoiding his gaze.

Dean groaned and hung his head. "You already know what's causing it, don't you?"

"I-I…" Cas…stuttering? Dean sighed and reached out, tilting Castiel's face up so the angel was forced to look at him.

"What do you know Cas?"

"I didn't want to jump to conclusions. I wanted it to be because of something other than…" His eyes flickered off of Dean's gaze. "Because of something else."

"Nice backtracking attempt. Now spill." Dean waited patiently. Cas was fidgeting, his wings shifting as he did. The dark chocolate feathers caught every ray of the dying sun, flickering in coppers and bronzed browns. There was something in the way Cas kept looking away, the way he refrained from staying too close to him and tensed under his touch—something in the way he flushed and stammered, like he was shy…like he was hiding something embarrassing…something embarrassing regarding the mention of their "bond" which he had never seen Castiel falter at mentioning. There had to be something different going on…Dean's eyes widened in sudden, stark realization. It was their bond! All those thoughts he had been having, all the feelings he had pushed aside...feelings about Cas that had grown into something that was far beyond an angel and his ward. He didn't know why that sudden realization would cause the wings to show, but he was sure that it was such a rare happening that they wouldn't find any info on it anyway. He looked at Castiel, meeting that shockingly blue gaze with his own.

And seeing that proverbial light bulb go off behind Dean's eyes, Cas saw, to his almost horror, that he had caught on. That he knew about his feelings towards the hunter...and things were going to get awkward, he knew it.

"I better g—" He was backing away, about to vanish, about to run and Dean seized his chance, by catching the front of Cas' lapels and yanking him forward until he had successfully captured the angel's mouth in a crushing kiss. He had no idea what was going to happen, and kept expecting for Cas to either just disappear, or give him a right hook that would take his head off his neck.

When neither of these happened, and instead he felt Cas relax, he pushed forward, deepening the kiss, nipping at chapped lips until they parted. He ran his tongue over Castiel's bottom lip, smiled when the angel sucked in a sharp breath, and began to coax his tongue into a heated battle of dominance.

Castiel learned quickly, practically melting against Dean as he ravaged his mouth, becoming as soft and pliant under Dean's rough hands as he could. Dean's hands left his lapels, tangling in the soft hair at the base of his neck, and wrapping around his waist, holding him there, pulling him as close as possible. The hand that was on his waist, inched higher, until Dean felt soft feathers. Cas moaned into his mouth as Dean's fingers massaged the area where wing met back, and Dean felt Cas press even closer to him.

When they finally needed air…well, when Dean finally needed air, they parted, Castiel staring dazedly up at Dean, his lips kiss swollen and red, and his eyes slightly unfocused. Dean cupped his cheek, smiling.

"See what you would have missed if you had run away?" His fingers carded through the feathers at the base of his wings, and he smiled when Cas shivered.

"I don't understand…"

"Thought I was makin' myself clear."

"I didn't think—" He flexed his wings and Dean brought both his hands up to run over them, pushing through the feathers, petting them down, fixing a few he saw were out of place. Castiel made a happy keening noise and leaned against Dean, his wings opening up even more and allowing him better access.

Dean placed a kiss on the top of Cas' head, inhaling the scent of his hair. Castiel tightened his arms around Dean's waist and sighed happily into his neck where he had been placing light kisses.

"Hey Cas?"

"Yes Dean?"

Dean scratched lightly at the bend of the wings and Cas shivered again. "I told you it wasn't the end of the world."

Castiel pulled back so that he could meet Dean's eyes.

"Honestly," he started, closing the space between them so their lips were almost touching. "I don't think I would have minded if it had been."

Short epilogue!

Sam glared angrily out at the road where he stood holding both his and Dean's bag. He HAD been out there for hours, gone into the café, eaten, then come back outside to wait impatiently some more.

If it wasn't for the "Runnin late, Cas needed me" text he had received a few hours previous, he'd have thought Dean was dead out in the desert somewhere.

So when the impala finally made it over the small hill and into view, Sam was happy his brother was still breathing, but pissed at having been left for so long.

He was about to bitch when the car finally stopped and he flung the door open, only to get a good look at Dean. Dean had the stupidest smile on his face, his hair was unkempt and rather tasseled, his clothes slightly crumpled, and there was something else…something Sam had trouble understanding.

Sam slid into the car, complaints dead in his throat, and just stared at his brother; unable to ask the question he was almost certain he knew the answer to now.

Dean just turned and grinned at him. "Ready to go, Sammy?" was all he said. No "sorry dude" or "jeez, how about my effed up day!" just a friendly greeting and a smile—like he hadn't left Sam in town for hours. With no response, he threw the car into gear and sped off as soon as the door shut and his brother was in…but Sam was still staring hard at Dean as they continued towards their next destination; staring hard enough that Dean finally scoffed and turned to look at him.

"Whatcha lookin' at there Sammy boy? I know I'm handsome, but the no blinking is staring to get a little freaky." He laughed.

"You have feathers in your hair…" was the deadpan reply.

Dean choked on his own spit and nearly drove into a ditch.
