Ended up using OC's for their kid well kids.

15 Years Later

"Dad, I'm going to kill James!" Axel growled out. "He was in my room again and he destroyed my video games."

Dean groaned looking over at Axel. "Can't you just beat the shit out of him like a normal sibling? I beat up Sam all the time."

Castiel smacked his chest. "Don't threaten to kill your little brother, send him down here."

"So you can ask him to not mess with my shit?" Axel glared at his omega father.

"What else am I supposed to do, spank him with a stick?" Castiel sighed and stood up.

"Why not, my friend Jeremy, his dad beats their omega son all the time, it's legal?" Axel looked so okay with it, Castiel could almost cry.

"Don't ever say that! That is not okay!"

Axel glared at him with those amazingly green eyes. "Why, because you're an omega? It's not like Dad doesn't ever hurt you."

Castiel flinched and ducked his head. He didn't know how to respond to that, he couldn't.

Dean rested a hand on Castiel's arm. "That's enough, go to your room!"

"Why because it's true! What's the difference between Daddy and James?"

"Unless you want a stick to your ass, go to your fucking room."

"I hate you!" Axel stormed off to his room and slammed the door, they could hear it from downstairs.

"Are you okay Angel," Dean asks wrapping an arm around him. "He was just angry didn't mean it."

"I'm fine Dean." Castiel stared down at his feet. Dean had a temper it was true but he never beat Castiel like he had that one night so long ago. He tried hard to overrule any other thoughts in Axel's mind that he was better than omegas. It didn't help that Dean was still very omegas need to be ruled by alphas.

"Are you sure? I can go yell at him some more if you want."

"It's fine Dean, I'm going to talk with James though." Castiel kissed Dean lightly before getting up and heading to their son's room.

James was sitting on his bed staring at the wall.

"What's wrong," Castiel asks, sitting on the bed next to him.

"Axel yelled at me. I didn't mean to break his video games, Daddy, I really didn't." James pouted, sticking out his bottom lip.

"You know you're not allowed in his room." Castiel sighed. He hated having to punish his son in any way; he didn't want either of them to end up hating him. "I think it's only fair that you don't get to play your games until we get at least a couple of his replaced. How many did you break?"

"Only three, I was going through them and I accidentally left them out and Axel stepped on them when he went into his room."

"Alright well in that case I get to take three of your games and you can get them back later. Okay?"

"Okay Daddy."

Castiel embraced his son, pulling him in close. He loved his son. Both of his children were precious to him. He looked down at his son's arm and tears pricked his eyes. There lied Dean's mark. He would never forget the day it happened, every last part of it was implanted into his mind.

Dean had to hold Castiel back as Leanor burned his child with the hot metal. Castiel screamed at her to stop, that if she touched him with it, he would kill her. James was crying for his dad's.

When it was done, Dean let Castiel go and he ran to his baby. Dean stood by watching as his omega unstrapped their son and cradled him close as he took him up to his room. The alpha followed behind making sure that James was alright. He watched from the doorway quietly as Castiel and James laid together on the bed. If either of them saw him, they didn't say anything.

They talked for a while about the cruel world they lived in before James had cried himself to sleep.

Castiel had left him soon after, pausing when he saw Dean in the doorway. "How long have you been there?" he asks, his voice a whisper.

"Since you came up here," Dean replies quietly.

"You had no right to do that." Castiel growls still being quiet and brushing past him.

"Cas," Dean groans following after him. "You know I didn't have a choice. Did you want him to get taken away from us?"

"We already make him wear that damn fucking collar; it's not fair that he has to go through this. You heard him crying and you just stood there. You just stood there as our baby cried for us. You put him through this." Castiel didn't turn on him and his voice never rose.

"As I said, do you want him taken from us?"

"No."

…

"You boys have gotten so big," Lucifer says, smiling at them. "How old are you now?"

"I'm fifteen," Axel replies smiling at him. Lucifer was such a cool dude.

James was hiding behind Castiel and Dean. He was always shy around new people or people he'd only met a few times. Lucifer was especially scary. He peered around Castiel and up at the alpha. "Seven," he whispers.

Lucifer smiled more directly at him. "Look at those eyes, they are such a pretty blue." James had black hair and blue eyes just like Castiel contrary to Axel's green eyes but he also had black hair.

James closed his eyes and buried his face into Castiel's sleeve.

"He's shy," Dean says reaching over and patting his son's head.

"I see that." Lucifer chuckled and turned his head just in time to see the three siblings come charging down the stairs.

"Hey squirt," Balthazar calls, wrapping an arm around Axel's head and ruffling his hair.

"Let me go you jerk," Axel cries out trying to protect his hair and dislodge his uncle.

Lucifer glared at Balthazar but said nothing, he would yell at him later.

Anna smiled at James, giggling when he took a step away from her. "Don't tell me we have to re become friends all over again. I thought we were buddies last time you were over."

Gabriel stood a distance away from them staring at Axel. He was definitely a handsome boy, even his braces only made him more attractive. Every part of him hated himself for ever trying to kill him. He still remembered holding him in his arms for the first time.

Castiel held Axel close to himself staring at Gabriel like he was a lion staring at a fawn. Every muscle in Dean's body was tense like a cobra ready to strike.

"Cas I promise I won't hurt him, I just want to hold him."

"I know, I just," Castiel held the boy tighter to himself but not nearly enough to hurt him. "If something happens to him." His blue eyes looked up meeting hazel strongly. "You hurt a hair on his head, and I'll end you."

Gabriel completely believed him. "I won't hurt him."

Castiel carefully maneuvered the child so Gabriel could take him but hovered over top of him as was Dean.

"Hey Axel," Gabriel whispers. "I'm your favorite uncle okay? Just don't tell Balthazar."

Gabriel smiled contently as Castiel had to pick up James for Anna to even come near him. The boy hid his face in Castiel's chest and clung to him. He certainly acted just had Castiel did when he was young and met new people.

…

Sam and Axel had a relationship that no one not even them could explain. They had always been close.

James on the other hand did not have that type of relationship with Sam. He hated how Axel was always the favorite of their uncle. He definitely had a stronger relationship with Castiel though. Axel and Castiel clashed constantly but never James. James was a mommy's boy in a sense.

Then there was Dean. Axel and Dean would play sports together and talk about guy stuff. The alphas never seemed to want to include James in on their fun. The one time James did join in a game of football; Axel fell on him and broke the omegas wrist.

Yet, James never fell like Dean played favorites. They had their own things. Like how they would watch reruns of Doctor Sexy for hours on end. Plus Dean would baby James and made sure he felt loved.

Everyone par Ruby loved James. Probably because he was an adorable boy who listened all the time. Axel would give you hell and back before he listened and even then it was a battle. That was probably why Ruby liked him.

The End

I am officially done with this series. I'm taking into consideration writing a book about Castiel as a child but it's distant and probably won't happen. I hope you all enjoyed this series and thank you for reading.
