Chapter 1, Brother my brother

"Finally! I'm freakin' starvin' here, lets hit the diner in this town." Dean Winchester said stepping out of his 1967 Impala, looking around the tiny town of St. Peters IL. "So what are we doing here again?" He asked shoving his hands into his pockets as he turned to look at the Angel named Castiel.

Castiel was quiet as he stared at the town with his vacant expression. As usual.

"Cas?"

"It's important business." He said flatly as the dark haired man in the trench coat walked up to the diner.

"Gonna tell me what that /business/ is, oh chatty one." Dean mocked.

"I heard he was here looking for me."

"Aren't they all looking for you buddy? You kind of went psycho on them."

"He's not like them..." Castiel said turning his cold gaze at Dean who raised his eyebrows and shook his head.

"Oh really?"

"Yes... but he's not going to just come out and show himself... He's... also going against the higher ups coming down here... he's not allowed on earth." Castiel said as they sat down.

"Well... where do we start looking? What's this dick like?" He asked showing very little interest in looking for another dick bag angel.

"Don't call him that." Cas said sounding very upset. "He's not like them, he's not like me... he's the guardian of innocence... and my little brother." He said folding his hands together, taking a deep breath.

Dean couldn't help but raise his eyebrow at his angelic partner and turn his head slightly, still staring at him. "...Innocence? Little brother? Aren't they all you're brothers?" He asked not really following where Castiel was going with this.

"Its complicated, but I care for him as you do for Sam..."

"Any idea what he'll look like?"

"A child... between the ages of 7 through 13..." Castiel answered, which surprised the hell out of Dean.

"You're being very to the point with me... are you feeling ok?"

"I'm fine Dean."

"Yeah okay... what's really going on here." He said having a hard time trying to buy that Castiel was just giving him forward answers.

"The angel of children, the creator of the tree of life, the protector of Innocence! Dean, he's in trouble, and he's been my responsibility for thousands of years... He can hide from us though, only children can see his true self."

"But I'm not a child Cas, where do I fit in here?" He said crossing his arms frowning.

"I thought you liked kids."

The reply left Dean a little speechless, not expecting to get nailed like that by a seemingly emotionless angel. "Alright... I see you're passionate about finding him, and we'll get him, I just don't know how /I'm/ going to be any help." He said rubbing his temple.

"Headache?"

"Kind of."

"Let me fix it for you." Castiel said and reached out to touch Dean who pulled away.

"Its not that bad yet bud." Dean said, not sure why Castiel was changing the subject so quickly and so obviously. "Lets get a motel and than we can look for... uhh your friend... what's his name?" Dean said squinting at Castiel.

"His name?"

"Is there a freakin echo in here? Do you always have to repeat my questions back at me?"

"Yes." Castiel said standing up and walked outside, making Dean roll his eyes. Sometimes this man got under his skin, and others he was completely amusing to be around. At least Castiel seemed to be trusting of him, even though he was a little depressed that Sam wasn't around, but he still didn't trust his own flesh and blood.

Dean tossed his bag on one of the motel beds and let out a sigh. "So where do we start plan master?" Dean said not bothering to take his shoes off or his jackets since he was pretty sure Mr. Insomnia was going to be keeping him up all night till they found this angel.

"The local hospital."

"Why?"

"We need to find if any mothers here were Virgins when they gave birth... that will be his vessel."

"Right... because that's not weird... Virgin mothers? like Mary, Jesus' moth-" Dean paused as his thoughts went ahead of his words for once and his eyes widened slightly. He opened his mouth and Castiel knew what he was going to say and answered him before he could get anything out.

"No. He never used Jesus as a vessel... but he could have been." Castiel said flatly, hands in his pockets as he looked around the room, picking random things up to look at them.

"Welp, lets get going than shall we?" Dean said heading towards the door. "Does this guy even want to be found by you? Why doesn't he come to you?" Dean said raising an eyebrow.

"Maybe he'll find us first. Though its a school day... he's probably at school."

"Why?"

"Because he likes to pretend to be a human child, just to see how they are doing in this world."

"Why are you telling me all this?" Dean snapped raising his voice at the Angel who sat on his bed.

"Don't you want me too?" Castiel said, surprised that Dean was upset that he was telling him answers for once. "You honestly have no idea who this Angel is do you?"

"No, I don't. Sorry to burst your bubble. But your not suppose to just tell me everything! You're supposed to make it a huge ordeal and we ARGUE OVER IT." He said holding his hands out in front of him as he spoke, Castiel just stared at him. "Don't look at me like that man. I mean it."

"Elijah... Dean... I- Never mind." He said looking away, letting out a sigh.

"That's what I'm talking about... Much better." He said walking over to sit next to his now frustrated angel friend. "I'll stop asking questions okay? And just go with it." He said patting the man on the knee, smiling when he saw the angel nod his head silently, biting down on his lower lip.

Dean noticed that Castiel was actually expressing something for once, but nervous panic was not something he wanted to see the ancient being to have. "Let's go." Cas said and stood up.

"We're walking." Dean said before the angel just teleported them somewhere, and was also surprised to see him just nod and head for the door. "What's gotten into you..." Dean muttered to himself quietly as he followed him out the door, wondering what this angel was going to be like and why Castiel looked so nervous.

Dean walked a little faster to get beside Cas and put his hand on his shoulder, thumb rubbing his back slightly. "Hey... it'll be okay." Dean said smiling brightly.

The angel turned and stared at Dean, no expression on his face for a moment. Dean was hoping for a smile, but when Cas thinned his lips, he took that as the closest thing to a smile he was going to get out of him. "Thank you." Castiel said as he got into the car. Dean watched and shook his head. He hated that he was starting to like Cas more and more, and than Jimmy's family kept popping up in the back of his mind as he got into the drivers seat of his car.
