A/N: Since I saw "The Song Remains The Same" I always thought that maybe that Dean knew Cas when he was little because Cas made his presence known to him but in a different way. So this starts out early on to the now. Will lead up to Destiel.

Chapter One: Cas:

"C'mon Cas, let's play!"

Mary caught her little toddler talking to "Cas" again. She had no idea who this "Cas" was. However, Dean talked about him often, and Mary started to think that he was just an imaginary friend. Until one Saturday after noon, she peeked her head in and found Dean playing with the angel figure that she bought at the yard sale for only 25 cents in room. She decided she wanted to know more about "Cas" and went in.

Mary knocked before entering.

Dean's head popped her way and smiled. "Hey mommy!"

"Hey baby, what are you doing?"

"Nothin'," he answered with a shrug. "Jest playin' with Cas." Dean gestured towards the angel that sat across from him.

"Really?" Mary asked kneeling down by her son's side.

Dean nodded. "I'm showing him my cars!"

Mary noticed the classic toy car collection that was scattered between him and his angel friend. Sometimes, when he could afford it, John brought some of the toy cars home from the garage for Dean to play with.

"And what does he think of your cars?" Mary continued.

"He says he doesn't understand them," Dean answered. "He says that Angels don't need cars. They fly!"

"And what else does Cas tell you?" Now, Mary, being the hunter of the family was careful with anything like this came along. She wasn't used to Angels yet but thanks to her and Bobby Singer's research they found tons of Angel lore.

"Cas tells me he's watching over me. He protects me!" Dean declared. "Like you always say, Angels are watching over me. I guess yer right mommy!"

Mary laughed and ruffled her baby's hair. "See, I told you. How about some lunch? Are you hungry?"

Dean's stomach answered for him. "Yeah!"

"Soup and cheese sandwich sound good?" she asked.

Dean nodded. "Can ya make some for Cas too?"

Mary hated to waste extra food but knowing Dean he could finish it himself and she would nipple on some too.

Mary got up. Before she left, Dean stopped her. "Nevermind mommy, Cas says he's not hungry because Angels don't eat."

"All right," Mary said and took another good look around the room before she went downstairs to the kitchen to fix some lunch. She made a mental note to go to Bobby's later to see if he found anything on an angel named "Cas".

"Again?" John asked Mary when he got home that night.

"It's just for a little while." Mary assured him as she tossed on her jacket. "Please, just watch Dean for me."

John sighed. "Fine."

Mary rolled her eyes and went out.

John sighed and sank into the chair at the kitchen table. Mary has been going out to Bobby Singer's house for a couple nights now. It was starting to get to him.

"Castiel?" Mary sounded out the name. It was a an odd name. Dean always had trouble with pronouncing the larger words. She smiled to herself, so that would explain "Cas" then.

Bobby was ready for her when she arrived. "Yup," he tossed her the thick book. "It's the closest thing I could find and I bet he's it."

Mary looked it over. There was no picture. Damn.

"From what I read though, he's a one Hell of an Angel," Bobby went on. "One of Heaven's most loyal soldiers in the field but don't let that fool ya, he's a major bad ass too. It's probably a good thing he's watching out fer yer little man there."

Mary shook her head. Demons were one thing. She knew all about them, but Angels was a whole new ball field. She looked up from the book. "Do you think it's possible Bobby?"

Bobby shrugged. "Got me, but since yer askin'... There's so much bad shit out there Mary why not belivin' in somethin' good fer a change?"

Bobby had a point. He always did.

"Tell me, how long has Dean been playin' with 'Cas'?"

It's only been awhile but if Mary had to pin point it. "I'd say since we found out we have another one on the way." Mary answered, her free hand drifted towards her stomach.

Bobby took that into consideration. "I'm gonna see if I can't dig up anythin' else."

"Thanks Bobby, you're a life savior." Mary handed him back the book. "I better get back. I think John is getting jealous."

That made Bobby laugh. "Of me?"

"Yeah,"

"He does know that I'm 'bout 20 years older than ya right?"

Mary laughed. "Man. That is ancient!"

"Watch it!" Bobby warned her with a playful pointed finger.

"It doesn't really matter these days Bobby," Mary continued as Bobby escorted her out the door.

"Ya Campbell gals always did have a thing fer older men." he played with her, recalling that Daddy Campbell was twice of the age that Momma Campbell was.

"Goodbye Bobby," Mary sang off and hoped into the Impala with Led Zep sending her off back on the road.

Back at home, John went to check on Dean who hadn't come down to see him since he got home. He snuck up stairs to his boy's room to see what he was doing. He caught him talking with this "Cas" again. It was starting to worry him a little. Yes, he realized that it was normal for a little boy to have imaginary friends at his age but Dean was getting older and it should have stopped long ago. He was glad when Mary got back because he had to talk to her about this.

"I'm back!" Mary declared as she walked into the kitchen.

John just came down the stairs and said: "I think something is wrong with our son."
