A/N: Hello readers. Long time no read, eh? Sorry for being gone so long-I needed time to think and get back into writing about Supernatural. Ever since hearing Castiel will be back (played by the AMAZING Misha Collins), I was literally jumping up and down. This is kind of my version of what happens when they see him. It's not good, but I wanted to write this which was creeping into my head. I hope they are not too OOC. So enjoy!

"Are you sure?" Dean asked, holding the phone close to his ear. "Where did you say this place was?" He scribbled down an address, and then gave the address to Sam, who gave him a questioning look. "Thank you." Dean hung up and put his phone away. He grabbed his jacket and was almost out the door when he heard Sam say, "Hold up!"

Dean turned around, obviously in hast to get somewhere. "You're not coming? Fine, give me the paper and I'll drive there myself." He reached his hand out.

"No, I'm going," Sam said, grabbing his own jacket. "I just want to know why you are in such a hurry."

Dean gave an exasperated sigh. "It's Cas."

"Cas?" Sam repeated, obviously in denial. "But his…"

"Look, I don't know how, but the person who called said that Cas only knew his was and he had my number," Dean said. "I'm only going to look and see what happened."

Dean left the house with Sam trailing behind. They hopped into the Impala and drove off. The drive was silent, but Sam could feel anxiety and anger from Dean, and it unnerved Sam. They arrived within an hour and went inside to the building. It looked like a hospital, but it was more of a patient care facility for mental people. Dean walked up to the counter where a young lady was sitting in front of a computer.

"'Scuse me," Dean said. "I'm here to see your patient Cas."

The lay looked up with tired eyes. "Third door down the hall to your right."

Dean thanked the lady and then hurried down the hallway. He paused when he approached the door and turned to Sam who gave a 'go on' gesture. Dean took a breath and went inside. The room was dimly lit-as if it was almost pitch black. Dean's eyes wandered about the room slowly, his eyes coming to rest to the bed in the middle of the room. There was a dark-haired man dressed in white scrubs looking at Dean and Sam with deep sad blue eyes.

"Cas?" Sam ventured to ask. Castiel turned to look at Sam for a moment, then to Dean.

"You son of a bitch," Dean whispered. "How are you alive?"

Castiel blinked, and tilted his head slightly. "I do not know. You are Dean, right?" He looked to Sam. "And you are Sam."

Sam cast Dean a confused glance which Dean returned.

"Cas," Dean started, taking a breath, "do you remember us? At all?"

"I only remember your names," Castiel said. "And I remember my name, and that I was an angel."

"Was?" Sam repeated. "Are you saying…"

"I do not know," Castiel sighed, shifting his eyes to the floor. "I woke up with the feeling that I had to help two guys." He raised his eyes. "You guys."

Dean swallowed and looked at Sam, who gave him a 'what do we do now' look. Dean didn't have the answer to that.

"I feel that I have done terrible things," Castiel said, "but I want to somehow make things right, and I acknowledge that it will not be easy."

"Damn straight it won't be easy," Dean grumbled.

"I'll find some way to redeem myself to you Dean," Castiel said with such sincerity that Dean's chest hurt.

"Yeah, well, one thing at a time," Dean said and turned to Sam who was pacing frantically. "Sam?"

Sam grabbed his gun and pointed it at Dean, his face terrified.

"Whoa, Sam!" Dean said, raising his hands. "Calm down!"

"Don't move!" Sam warned. "Tell me where me brother is!"

"Sam I'm right here," Dean yelled. "Snap out of it."

"Sam is seeing Lucifer," Castiel said. "Lucifer is making the illusion that you are lying dead in front of Sam."

"Can you see Lucifer?" Dean asked.

"No, but I can feel him," Castiel responded.

"Sammy, I'm real," Dean said, taking a step forward.

"I said stop!" Sam yelled and fired at the floor.

Dean's jaw clenched and looked at his brother he tried so hard to protect all these years. "Sam…"

"Tell me where my brother is!" Sam shouted, raising the gun again.

"I'm right here Sam!" Dean said. "You can make Lucifer go way, I know you can. Please Sammy."

Sam watched with wary eyes. "How do I know you're not a Leviathan?"

Dean could tell Sam was trying to recollect himself and relief washed over Dean for a moment. "Look, I'll show you." Dean slowly drew out his knife and lifted it to his arm. He bit back a gasp as the knife sliced into his skin; he raised his arm to Sam. "See? No black goo. Red. Real. Human. Blood."

Sam looked from Dean's arm to his back and back. After a moment, Sam gave a heavy sigh and lowered his gun.

"Sam," Dean started, advancing forward, but backed away when he heard Sam yell, "Stop!"

Dean's heart split as he watched how torn Sam was to get back to reality. He watched as Sam's eyes drifted to Castiel.

"You," Sam said in a dangerous tone.

"Sam," Dean warned, but Sam had already advanced toward Castiel. "Sammy!"

Sam picked up a rusty rod and swung it at Dean. The impact made Dean fall hard on the ground. Dean held his head, groaning and lifted his head to see Sam aim the gun at Castiel.

"Sam, stop!" Dean yelled, jumping to his feet. Castiel seemed to be watching in a daze, and he didn't look like he was going to even attempt to defend himself. Dean jumped in front of Castiel and knocked the gun out of Sam's head. Angered, Sam immediately grabbed Dean by the jacket and punched him twice in the face before throwing him aside. Dean crashed into the nightstand by the bed, and he looked up to see Sam swing at Castiel.

"Sam, stop!" Dean yelled and struggled to get up; he took a step forward as Sam pushed Castiel through a nearby window. "Cas!"

A/N: So, this is something different from my other story, but we'll see how it goes. There might be just one more part, but I'll leave that up to you.
