I will protect you:

Dean hated it, he hated everything. If Sammy wasn't still around he would have probably already ended himself. He couldn't save Cas, but he couldn't kill him either. Sammy seemed to be less reluctant to off him which hurt Dean even more somehow. Cas was turning into a monster, and he couldn't stop it, any of it, he couldn't protect him. Dean sat against the bathroom door as sobs wretched out of him. His knees curled into his chest. It was so unlike him, but he couldn't care less, he needed a release.

He silenced himself quickly as he heard Sam begin to unlock the door and walk inside. "Dean, you in the bathroom?"

Dean composed himself enough to control his voice. "Yeah" He said gruffly.

"Alright, well I just got a call from bobby, he says there's some demon activity a few towns over. Wanna check it out?" Dean began washing his face yelling out a "sure" before emerging from the bathroom. Dean rubbed his neck with the towel, trying to calm down a bit, get his mind ready for a hunt.

"Demons huh? How many?"

"Dunno, the signs aren't too strong."

"Cool. Well let's get this over with." Dean began to prepare salt rounds while Sam packed up the car. Finally they were off. When they pulled into the small town, it was completely empty. "Oh this can't be good," Dean said, looking out the window at the empty streets. Sam shook his head in agreement.

"Not good at all"

Dean pulled his baby over and parked next to an empty eye clinic. Sam and Dean grabbed their guns and their knives and made their way to the center of the town. "Trap?" Sam asked looking warily around. Suddenly a flush of people ran at them from all sides. "Yep" Dean shot towards the large crowd to his left and it wasn't long before the people were close. They ripped and slashed at the brothers who kicked, punched, shot, and stabbed anyone who got too close. Soon they ran out of bullets, and were being overwhelmed. "Where are all these fuckers coming from?" Dean growled fighting off a thick woman. Sam was about to reply when he was pulled into a crowd of them who covered him until Dean couldn't see him. "Sammy!" Caught off guard, demons grabbed Dean's wrists, he watched as one grabbed his knife and reared back to plunge it into his heart. So this is how it ends He thought, cringing at Sam's yells. He closes his eyes.

A mass of shrieks fill his ears as the grip on his arms loosens. He pulls free and watches as the black smoke begins to fall from the demons mouths. The in a matter of seconds each one of their heads turn towards the sky, black smoke spewing from their mouths. The people fall limp to the ground. Exhausted Dean falls to his knees. He looks desperately for Sam among the bodies and finds him coughing and pushing people off of him. Dean crawls towards him, "Sammy, d… did you?" Sam looks at Dean in disbelief and shakes his head hard.

"I don't think so." Dean squints against the sun and sees Sam's eyes widen, focused on something behind him. Dean turns to see Castiel standing above him, looking down into his eyes hard. "C…Cas"

"Hello Dean"

"I… I don't" Dean tried his hardest to think of something to say but his mind went blank as Cas leaned towards him and lifted his face a little with his long pale fingers.

"I will protect you" Dean Felt the soft ghost of lips against his own send a shock through his body.

"I knew these two beefcakes would lure you in Cassie." Cas turned and stood face to face with Crowley, "We have some unfinished business, love. You know, you're very naughty for running off." Crowley waged his finger at Cas, who stood glaring hard at the man. "Come now puppet, you've saved these boys, now come with me or I will do much worse to them." Cas' gaze faltered. He looked back towards Dean and Sam.

"Don't listen to him Cas!" Dean yelled out, trying to stand but failing. Cas winced.

"If I come with you," Cas began, his voice a low rumble, "You will never bother these two again, or anyone they love. You will keep your hands and the hands of your demons and monsters away."

Crowley let out a sigh then smiled. "Of course, I promise I will never touch a hair on their pretty little heads, now come." Cas nodded and turned to Dean leaning close to him, brushing his hand across Dean's cheek.

"Cas don't… please" Dean was desperate and close to tears, though his pride tried to hide them. Cas lent down and captured him into a final, loving kiss.

"I will always protect you" Then he and Crowley were gone.
