Sam, Dean, BJ and Bobby were at Bobby's house. Sam was sleep in the guest room. BJ was on the computer and Bobby and Dean were outside talking.
"Honestly Dean I have no idea what's wrong with Sam." Bobby said.
"Maybe it's something supernatural." Dean said.
Bobby looked over at him. "You really think it is?"
"It could be." Dean said "You know for us it's never normal."
Bobby sighed "Maybe"
"I know a way we can be sure." Dean said.
"How?" Bobby asked
"CA's, I mean if anyone would know its Cas right."
"Yeah maybe" Said Bobby.
Dean closes his eyes "Castiel, I know we haven't spoken in a while but we really need your help, please." Dean opens one eye and looks at Bobby who's smiling. "Why are you smiling Bobby?" Dean turns and jumps "Damn it Cas."
"Sorry" Castiel said.
Dean chuckled "It's good to see you Cas."
"Good to see you to Dean." Castiel looked toward the house. "So where's Sam?"
Dean looks curiously at Castiel "How did you know it had something to do with Sam?"
Castiel looks at Bobby then back at Dean "I'm an angel Dean."
"Right well-" Dean then got feeling something was wrong.
Bobby looked at Dean "What is it Dean?"
Dean turns to the house "BJ" Dean ran full speed back into the house. BJ was unconscious on the floor. "BJ" As he got closer to BJ he heard Sam screaming upstairs. He looked back at Cas and was about to say something but Cas disappears. Dean looks back at Bobby "Go help him I got BJ."
Bobby goes up stairs to help Castiel with Sam. Dean takes BJ to the demon proof room in the basement and locks him in there. He then follows Sam's screams to the guest room. He walks into the room just as Bobby and Castiel were killing the last demon. He walks over to Sam who was still kicking and screaming. He holds him down and tries to wake him up. Castiel walks over to them. "Cas what's wrong with him?"
Castiel comes over to them "You need to hold him down."
Dean looks up "What why?"
"Just do it Dean or he'll die." Castiel says.
Dean looks at Bobby "I need help Bobby." Bobby comes over and helps Dean hold Sam down. Sam was trashing harder now as Castiel reached inside his stomach.
"Dean, hold him down!" Cas yelled.
"I am trying." Dean shouted "He's to fucking strong."
"I almost got it." Castiel said
"Got what Cas. What the hell are you talking about?" Sam's screaming got louder and louder and Dean was scared. He looked at Bobby then back at Sam. All of a sudden the screaming stopped and Castiel removed his hand. When he pulled it out it was covered in ash. Dean looked at Castiel then at Sam's lifeless body. "What did you do?"
"He'll be fine now." Castiel said stepping back.
"What the hell did you do Cas?" Dean said "What was that?"
Castiel looked from Dean to Bobby. "Come on" The three head back downstairs. "Ok"
Dean walks over to Castiel "What the hell was that Cas?"
"Your brother was slowly and painfully giving birth to a demon." Castiel said wiping his hands on his coat.
Bobby bursts out laughing causing Dean and Cas to look at him. "What? A demon, are you serious?"
"Yes" Castiel says simply.
Bobby's smile fades "How is that possible. I've been looking out for them for years. Nothing has ever come near them."
Castiel sighed "Jason howl"
Dean looks at Castiel "Who's that?"
"A guy that Sam" Castiel stopped.
"That Sam what?" Castiel looks down and Dean sits down on the couch "He was with another guy?" Dean looks at Bobby "Did you know that?"
Bobby held up his hands "No idea I swear."
"Look this guy was a demon and he got Sam pregnant with a demon and this baby would kill Sam and destroy the world."
Dean looks up at the stairs "But why now?"
"Because you left Dean. You were the only thing keeping them safe. The amulet you were wearing was made to protect all of you. Why do you think you were never harmed on the battlefield? The amulet protected you." Castiel walked over to Dean.
"And no one protected him." Dean buried his face in his hands.
Castiel put his hand on Dean's shoulder. "It wasn't your fault Dean."
Dean looks up at Castiel "No it's yours."
"What?" Dean gets up and Castiel steps back.
"You knew and you let it happen." Dean said.
"I needed to kill that demon Dean."
"But you had to use Sam as bait. Why didn't you tell me?" Dean cried out.
"Because I knew what would happen if I did. I knew you would have tried to interfere and screw everything up."
Dean got up grabbed Cas by the neck and pushed him against the wall. "He almost died because of you. BJ's unconscious because of you." Dean then remembered BJ and runs back down to the basement. He heard BJ yelling inside. "BJ!"
"Dad!" BJ was banging against the door.
Dean opens the door and BJ runs into his arms. "Hey it's ok."
"I'm sorry dad I'm so sorry." Despite what just happened Dean was smiling. BJ had finally called him dad. He had finally trusted him and let him fully into his life. "Where's is he? Is he ok?"
"Yeah you want to see him?"
"Yeah" BJ said.
They head back upstairs. Walking into the living room he stops. Looking back at BJ he tells him to go on. BJ heads upstairs. Dean walks over to Cas and holds out his hand. "Thanks Cas"
Cas takes Dean's hand and shakes it "You're welcome"
Dean heads upstairs. Walking in the room he sees BJ sitting next to him on the bed. He walks over to the other side. "How are you holding up?"
BJ looks over at Dean "I'm good, you?"
"Better now." Dean looks at Sam then BJ "Hey, have you ever meet someone named Jason howl?"
BJ looked up at Dean "Yeah he and-"
Dean looked down "How long?"
"A couple months. He broke it off because of you. Why is something wrong?" BJ asked.
"It's nothing" Dean said.
"I wanted to write to you." BJ says quietly.
Dean looks up "What?"
"When you were in Afghanistan. I wanted to I just didn't know what to say."
"It's ok but you do know you called me dad right?" Dean smiled.
"I know because you are my dad and I'm really sorry for all the crap I put you through."
"Don't worry about it." Bobby and Cas walks in "Hey glad you're still here. This is BJ, BJ this is Castiel."
BJ gets up "The angel right, dad told me all about you. All the times you saved him and looked out for him. He really cares for you."
Castiel smiles "I care for him too." Cas looks at Sam "We should let rest in peace. He'll be fine."
Bobby, Cas and BJ headed back down stairs leaving Dean. Dean kisses Sam on the head and puts the amulet around his neck. "I love you Sammy." Dean gets up from the bed and left, closing the door silently behind him.
