A/N: Hello fellow readers! This is a new story I've started. It's based off a dream I had about two nights ago. I was going to make this a one-shot (because that's how far I had gotten in my dream), but I thought it would be kind of unfair, so I've decided to do a follow-up chapter and then an epilogue. So enjoy!

The Winchester brothers were sitting at the table: Dean drinking a beer and Sam searching on the computer for a new case. They had completed a recent simple ghost hunt two days ago and Sam insisted on getting another case. They were sitting silently until Castiel flew into the room suddenly. Both jumped slightly at the angel's sudden appearance. Castiel had flown in rather heavily-instead of just appearing, Castiel was leaning against a table for support.

"Cas!" Dean exclaimed, jumping up from the table. "What's wrong?" He couldn't see any wounds on the angel.

Castiel looked up wearily. "I need to go… to a place," Castiel said.

"Couldn't you just zap yourself there?" Dean asked.

"I don't have the strength," Castiel answered forcefully, sitting on a chair.

"Where is this place?" Sam chimed in; Dean rolled his eyes. Leave it to his brother to take immediate action.

"It is not too far," Castiel said. "It's a sanctuary nearby."

"The Sanctuary of Mary?" Sam asked. "That's about half an hour away." He looked at Dean. "We could take him."

Dean grumbled something under his breath along the lines of 'freaking angel' but grabbed his keys anyway. They made their way to the car rather slowly. Castiel stumbled twice on the way, with Dean staying close beside the angel. When they got into the car, Dean turned the Impala on and started to drive.

Dean checked in his rearview mirror occasionally to make sure Castiel was conscious. "What happened Cas?" Dean asked. "Where you in an angelic fight?"

"No," Castiel replied groggily. "I just know… feel that… I have to pray… to my Father."

Dean frowned, gripping the steering wheel a bit tighter. "Is your power drained?"

A pained growl was the only response from the backseat.

"Cas?" Dean asked. "You okay back there?"

"You think he's okay?" Sam asked almost snarkily back.

"Damn it," Dean growled and stepped on the gas."

They made it to the sanctuary in half the time due to Dean's speeding. They parked outside and then got out; Dean had to almost drag Castiel out because the angel was half out of it. The sanctuary was peaceful, the only sound being water from a fountain in the center.

"There," Castiel rasped, pointing to a circular platform in front of the fountain. Dean made a motion to help Castiel but Castiel insisted on walking himself; Dean stood by close anyway. When they finally got to the platform, Castiel kneeled and closed his eyes, bowing his head.

"I'm going to get some weapons," Sam said. "I have a bad vibe about this."

Dean nodded and watched his brother walk to the car and then turned back to Castiel. Dean was truly afraid for Castiel; his breathing was labored and he was too pale. Dean wanted to know what-or who- had done this to Castiel. It had been only a month that Meg had called, saying Castiel had snapped out of the Lucifer hallucinations. The two brothers had immediately drove to the ward and got Castiel out. Of course they still had the Leviathans to worry about, but they had gotten Team Free Will back and Dean was happy with that fact. Since from years back, it seemed like, Dean had his brother back again, and Castiel.

Everything was going fine until a shadow shot forward from nowhere, crashing into Castiel who let out a weak yelp.

"Cas!" Dean yelled, rushing forward, knife drawn, but was held back by a force. "What the hell?" Dean growled, trying to escape, but the grip would not let him go.

"Watch your angel die," a demonic voice said behind Dean.

A sense of dread fell heavily on Dean. He watched as the shadow pulled out a knife, looming over Castiel, and then forcefully plunged the knife into Castiel's stomach.

"Cas!" Dean screamed, fear engulfing him. He struggled vainly against the rock grip. "Leave him alone you son of a bitch!"

The shadow glanced up, had the nerve to stare at Dean, and then went to resume its task. Every time the shadow stabbed, Castiel let out a pitiful cry of pain that wrenched and tore Dean's heart.

"Please… stop," Dean heard Castiel whisper and Dean couldn't help the tear that came down his face.

Sam rushed in holding a gun and fired at the shadow; it shrieked and vanished immediately. Dean whipped around as he felt the grip loosen and shoved the being that was behind him to the ground.

"Take care of him," Dean snapped, pointing to the semi-human on the ground.

Sam nodded and went over to the semi-human while Dean ran to Castiel.

"Oh god," Dean whispered, kneeling next to the angel. There was too much blood pooling around Castiel and the angel's eyes were closed. "Cas, please, open your eyes." He took a handkerchief out of his pocket and placed it on Castiel's stomach, trying to apply pressure to the wounds. There must have been fifteen or more wounds.

"Castiel, don't you dare die on me!" Dean heard himself say. "You're an angel. Only another angel can kill an angel and this isn't the case. You're going to be fine." Dean knew he was rambling, but he couldn't stop himself from shaking.

"Dean." The voice was so soft Dean almost didn't hear it.

"Cas!" Dean gasped. "Fuck you're still alive. Hold in there; you're going to be okay."

"Stop," Castiel whispered, his eyes opening weakly. "Don't try anymore."

"You don't know what you're saying," Dean snapped angrily. "I'm not giving up on you."

Dean glanced at Castiel's face, to his eyes. The blue eyes Dean had come to love were dull and glazed over, barely any life in them. He took out a bigger handkerchief and tied it around Castiel's stomach to try to stop the bleeding.

"Dean!" Sam called.

Dean glanced up to see his brother with his hands tied. The semi-human was up, red eyes blazing.

"Come with me, and I'll let you two live," it said.

"The Hell we're going anywhere," Dean growled. "You'll just kill us."

"I have no business with the two of you," it hissed, lashing it's pointed tail. "Drive me to where I want, and I'll let you two live. I give you my word."

Dean shook his head and looked down at Castiel; he couldn't leave him.

"Leave the angel," it said as if reading Dean's mind. "He won't make it."

The sentence made Dean's heart thump painfully he immediately denied that Castiel would die, he refused to lose his angel anymore. "I can't leave him."

"Then you and your brother will die," it said. "Don't force me to kill you two-I sincerely don't want to."

Dean stayed still, kneeling by Castiel's side. Dean felt it was not right at all to leave the angel. "Cas," Dean whispered, leaning to pick up the angel's head. "You stay strong for me, you hear? I'm coming back for you." Dean was startled when Castiel's eyes flickered open. Dean held the angel's face close to his so their foreheads were touching. "Don't give up, you hear me?" Dean whispered, trying to see the spark in the angel's eyes that would comfort him.

Castiel blinked tiredly. "I'll try, for you Dean," Castiel whispered in reply and closed his eyes, going limp.

"Cas?" Dean called, worried that the angel had died; he quickly checked for a heartbeat and breathed out a shaky breath of relief and then gently layed Castiel down before standing up. Dean shoved past the semi-human, grabbing Sam. "Let's go, demon," Dean growled.

They got into the car and Dean sped off, determined to take as less time as possible.

"Where are we going?" Dean asked, knuckles white as he gripped the steering wheel.

"A field," it said. "About fifteen miles ahead."

Dean glanced at his brother, who held the same curious gaze.

It didn't matter to Dean; he would drop of this demon, kick its ass out, and race back to Castiel because Dean was not going to let his angel die.

A/N: Wow, longest chapter ever! And sorry for stopping here xD This is where my dream had ended. I don't know WHY I dreamed this (I feel terribly sorry for Castiel T_T) but I wanted to write it out. We'll see what happens next time!
