Dean parked his Impala in the shadow of that large, old looking mansion. He hadn't had a clue that there was this kind of building less than 100 miles away from Bobby's house. Most of the large windows had been broken and nailed up, and green vines had taken over the facade, rustled the grout and invaded the mansion through couple of open windows. Charming is how Dean would have sarcastically described the place.

Once again he stood out from the car, slamming the door shut. Loud noise coming from it scared a pack of black crows into a fly from the large tree nearby. Sky had already turned dark, stars could be seen and the pink horizon disappeared behind the old house - last beams of light escaped from the sides of the building.

As much as Dean was trusty with the whole situation, he circled the car and opened the trucks. No way in Hell he'd enter that kind wreck of a house without equipments. He picked up his sawn-off shotgun, checking it out and stuffing his pockets full of shotgun shells he turned to face the house.

"This is the worst idea ever", he mumbled, almost starting to regret going here all on his own. Something in back of his mind still pushed the dubious thoughts away and so Dean approached the house quickly, climbing up crumbled stone steps just to notice that the large, dark wooded front door was open. He pushed it so he could lure through.

Hall was dark and large staircase lead to second floor.

"Cas?" Dean didn't have a time to waste, so he called out for him right away, hoping for an answer.

"Castiel!" His voice got louder and he walked through the hall, and climbed up the stairs.

"Answer to me!"

Strongly it seemed that the whole place was empty - Dean sighed and turned, he was ready to leave... Until he heard door creak at the end of the hallway going to left. He narrowed his eyes and started approaching the door slowly, holding up his gun, ready to face anything.

Dark marble made his footsteps echo from the walls. There was piles of dead leafs here and there. In all its gloriness it reminded Dean from the hiding place he and CAS had used while hunting down Lucifer when Sam was gone. Corner of his mouth twitched, maybe to turn down, maybe to turn into a smile.

"Cas? Is that you?" he called out, still not getting an answer. He pressed his hand against the door and pushed it open - almost blinding from the light coming from the room.

"Hello Dean. I've been studying these birds for a while now", familiar voice greeted him. Dean blinked his eyes rapidly - light slowly faded and there Castiel was other side of the large room which was furnished to suit the almost black floor. He sat on the windowsill, staring outside, where the crows croaked.

"Why'd you call me here?" Dean didn't have a time to mince his words, so he decided to cut the slack, the unnecessary bullshit talking and go straight to subject. Castiel turned to glaze him and smiled slightly.

"I need you, Dean." He stood up and wiped the dust off from his suit - trench coat was neatly folded on the large, grey armchair's back few feet away from him. Dean raised his eyebrow and looked at Castiel little incredulous.

"You don't need that, either", Castiel continued and nodded towards shotgun Dean was still holding. Along the nod something clicked in Dean and he just simply dropped the gun down; Thank God it didn't go off, was all he thought.

"Cas...?" Dean took one a bit awkward step closer. Castiel raised his chin, looking prideful.

"I need you, Dean. I'm the God, but I need my scions. Heirs..." he explained, pressing his palms together and walking towards Dean.

"I need you to bend on my every command."

It took a while for Dean to understand the exact words the former angel was forming from his lips.

"What the hell are you talking about?" he asked at last, pressing his fingers against his temple, like he was having another headache and looked little amused.

"You're going your brother's vestige, Dean." Castiel was so close, that Dean felt his breath on his face.

"You're already... Contingent to it, aren't you, Dean?" Dean took sharp breath between his lips.

"I don't know what you're talking about..."

"The energy, Dean. Energy. From Purgatory souls. The headaches are caused by lack of it. You can't sleep either, can't you?" Dean twitched.

"Stop your bullshit, Cas. You sound ridiculous, you know", he bawled, clenching his hands in tight fists.

"I... I can't sleep, because... I just can't okay! It's not rare for people in this situation." Castiel uplifted his brows and looked almost amused.

"Why did you come here in a first place, Dean?" he asked and walked past him, stretching his arm and closing the door behind Dean.

"What was exactly the thing that brought you here?" Castiel spoke out prolonged, emphasizing every single word. He turned and leaned against the door, blocking Dean's escape way.

"Cas..."

"I can see your face is all angry. Why is that, Dean?"

"Why did you come to see me then? I mean, days ago? When you popped up and awakened me? For... This?" Dean sounded upset, as much as he tried to cover it up.

"You seem to understand more satisfyingly than I thought." Dean turned and almost without thinking gripped Cas by a suit jacket and slammed him hard against the door.

"Oh. Let me go, Dean." It annoyed Dean, how calm Castiel could keep himself.

"So Sam was right, huh? About you being a monster? That we should hunt you down?" Corner of Castiel's eyes nibbled a bit, but otherwise his whole appearance staid cold as ice. He lifted his hands and winded his delicate fingers around Dean's wrists.

"You need it, don't you? You want to absorb it out of me. Like father like son, they say, but I must say, you Winchester brothers, you are special. Willing to die for each other... Willing to do anything, ANYTHING to gain some potency, vigour..." Castiel spoke out, staring at Dean's green eyes with his own bright blue ones. Dean slammed the door with his hand.

"Damnit, Cas!" he grunted between his tight squeezed jaws. He blinked his eyes - tears?

"You selfish, selfish bastard!" he continued, now yelling. Castiel just stared him blankly. Dean gulped - his mouth felt like bucket of sand at the moment.

"You... Are making a mistake here, don't you see? You're destroying yourself."

"No Dean. I'm becoming complete." Castiel smiled slightly, sliding his hands from Dean's wrists to his shoulders.

"You'll see one day." Energy bursted into Dean's body again. Stunning, luscious energy which made Dean want to fall on the floor and die, but he knew it was no good. He had to pull off.

"What is it, Dean?" Castiel asked, looking at his palms, with a "did I do something wrong" look on his face.

"You're a freaking devil, Cas", Dean panted, holding his chest with his hand as he withdrawed all the way through the room, until he slumped sitting on a same windowsill Castiel had sat on.

"That's... Where you're wrong. I have good intentions, Dean. You can try to stop me, but I promise, you won't succeed."

"I'd rather die than let your feathery ass run this world", Dean said right away, leaning his head on the cold glass.

"You almost did die."

"Fuck you." Castiel walked slowly to him, cupping his cheeks and making Dean look at himself.

"You still don't understand, Dean", he whispered, looking a tad sad for a fleeting moment. This time the touch was normal - Castiel was suddenly holding back.

"Cas, no", Dean uttered, giving a pained grin as tears uncontrollably fell on his freckled cheeks. He tried to pull his head off from Castiel's hold so he could wipe them off but it was no use. Castiel wanted to see it all. Pain. Tears. All of it. He studied, how Dean's lips shook, his eyes wandered around to avoid eye contact, how tears dropped and ran down... For him, it was somehow…

Beautiful.
