Chapter 6

The town of Uniontown was small and nondescript as the Impala rolled through it. Sam was on his cell trying to find the convenience store Cas was supposed to be waiting for them at.

"It's across town about five miles. Stay on this road and in two miles take a left on Willow for three and it should be on the right," Sam informed Dean before looking back up.

"Alright," Dean mumbled glancing at the odometer so he would know when two miles passed. He turned onto Willow like Sam instructed and drove down the two lane road stopping at red lights and slowing as he started looking for the store. He spotted the sign first ahead of them and signaled to turn into the parking lot. He pulled into a space and killed the engine.

Dean and Sam got out and moved to the front of the car as they waited for Jack to join them.

"Stay behind us," Sam told him before falling in step with Dean.

"Alright," he replied staying behind them as they walked around the building. Jack wasn't sure what was going on but felt it was something important. He felt the other angel before they found him and a tingling of joy raced through his body.

Dean spotted him first. He was sitting at a picnic table in a grassy area beside the building staring off toward the mountains in the distance.

"Cas?" Dean asked getting his attention as he looked around to be sure no one else was around or there was no danger.

Cas slowly turned and looked at the two brothers before standing and smiling at them. He stepped toward them as Dean moved toward him and when he was close enough grabbed him into a hard hug.

"It's good to see you Cas," Dean whispered before letting him go blinking back the tears. "I didn't think you would be coming back this time."

"It's good to see you too, and I'm at a loss how this happened," Cas replied. "Sam..." he continued turning to the younger Winchester.

"Cas, man, I'm glad you're back," Sam greeted him, wrapping his arms around him for a moment before letting go.

"Me too. Where's Jack?" Cas asked looking for a child. "Is he still in the car?"

Dean and Sam stepped aside to show Jack standing behind them staring hopefully at Cas. He took a step toward Cas before speaking.

"Hello Castiel," Jack greeted him, awe and happiness in his voice.

"Jack?" Cas questioned looking to Dean and Sam to be sure he was correct. He saw Dean nod his head yes and looked back to Jack. "You're not a child, you've grown. Have I been gone that long?"

"I am, seems I grew fast. I'm not sure why," Jack replied. "I can't believe you're here. I called out to you to come back because my Mom wanted you to take care of me and Dean and Sam wanted you back too."

Jack moved to Castiel and hugged him. Cas returned the embrace and looked over Jack's head to the brothers. He released him and looked into his eyes studying him.

"That is what I heard...Your voice in my head..." Cas stated looking at Jack curiously. "That is what woke me."

Dean and Sam looked at each other, a silent communication passing between them. They remained quiet, both thinking the same thing. Somehow Jack had brought Cas back from wherever he had gone. This was a big development showing just how powerful he was.

"Why don't we get out of here and continue this somewhere else more private?" Dean suggested when he saw a couple of people eyeing them. "We'll start back and get a motel room along the way where we can talk."

"Yeah, c'mon Cas, Jack, let's go," Sam agreed.

They led the two around to the Impala and got in to retrace their journey back to the bunker.

Dean opened the door to the motel room and looked around before letting the others enter the room. There was a knock at the connecting door between the room and the one beside it. Dean went to the door and unlocked the one on his side to allow Sam to enter. He had gotten two rooms with interconnecting doors so it would be easier for them to be together.

Everyone dropped their packs and moved around the room settling somewhere. Dean and Sam pulled chairs over closer to the beds where Castiel and Jack each sat at the foot of a bed. They straddled their chairs and stared at Cas and then at Jack who was looking at Cas, happiness and joy on his face before Dean spoke.

"Tell us what happened Cas. Do you remember anything?" Dean asked.

"I remember coming through the rift and I felt the angel blade being shoved into my back and then nothing. I died. Everything is blank, I ceased to exist, until this voice whispered in my head. It stirred me and I felt a surge of energy before I woke up."

"Where were you?" Sam asked.

"The Empty. That is where angels and demons go when they die. We are put in an eternal sleep for eternity."

"What was it like? I mean when you woke up."

"Blackness and nothingness all at the same time. I could feel that place trying to drain what life I had in me, but I wouldn't let it. Time didn't move there, it was frozen in a moment, a split second. I started walking through the darkness trying to find anyone or a way out. It seemed there was no end to it. I don't know how long I walked until I felt It. I was being followed."

"By who? Or by what?"

"It called itself the Entity and It ruled that place. It told me the Empty was older than the universe, even God himself. I was the first one to ever awake there and It did not like it. Me being awake caused it pain for some reason and this being tried to force me to sleep again but I fought hard and refused. I told the being I would never go back to sleep and to send me back to Earth and that would solve the problem. It kept trying for a long time, but I never gave up, I kept fighting and suddenly I woke up in a field about a mile from that town you found me in. I guess the Entity finally got tired of fighting with me and the pain I was causing and send me back to Earth."

"Well I don't care what it was, I'm just glad you irritated that thing enough for it to kick you out," Dean said when Cas stopped talking.

"Yeah, I'm glad you're back too Cas. We all are," Sam told him glancing at Jack for a moment before returning his gaze to Cas. He hadn't taken his eyes off Cas since they found him.

"Sammy, why don't you and Jack go across the street and grab a six pack?" Dean suggested wanting to talk to Cas alone. "Take your time."

Sam got the message and got up, "C'mon Jack, let's take a walk."

"Alright," Jack replied not getting the unspoken message that passed between the others.

After Sam and Jack left the room, Dean turned to Cas.

"We need to talk about Jack, Cas," Dean told him.

"What about him? Is something wrong?"

"Wrong? Other than him just being born about a week ago and he's already a teenager I think, hell I don't know how old he is...We know nothing about him or what he's capable of. He woke you from the Empty and that's never been done before. Can you sense anything about him? I mean Lucifer is his father."

"I don't know Dean, I've really not had enough time with Jack to understand him. I can feel his power and it's immense, but I don't think he realizes it. Jack is a child that has to learn what he can do and Kelly wanted me to teach him and look out for him."

"Do you think he can learn to control all this power? Is he going to be dangerous?"

"I can't say for sure. Maybe I can go to Heaven and see what I can find out," Castiel offered.

"I think we're going to need all the help we can get man. He could be a ticking time bomb here and I don't want him going off. If drastic actions are needed, we need to do it before he gets too strong and we can't stop him."

"I understand Dean, I will do what I can. I won't give up on Jack, I'll do whatever I have to to help him. Once we get back and I get Jack settled I will go to Heaven."

"We're hoping Jack can open another rift so we can go after Mom." Dean said. "So him learning to use his powers is top priority."

"What has happened to Mary?" Cas questioned.

"She stood up to Lucifer and almost had him until he jerked her into the rift and it closed on them," Dean told him not able to keep the pain from his voice.

"If there's a way we will get her back," Castiel tried to assure him knowing how much she meant to both brothers. "I will start working with Jack when we get back."

"We're back," Sam called as they came in the door. He looked over at Dean and Cas seeing they stopped talking when they came in. He would question his brother when they were alone and see if he learned anything.

"Good, I'm ready for a cold one," Dean said changing the subject and looking at Cas to be sure he understood to stop talking.

"I have beer," Jack announced holding up a bag pleased that he was helping.

"So hand 'em out kid," Dean told him, holding out a hand for a beer. "And no you're too young for beer," he stated when he saw Jack start to open his mouth making Sam chuckle and Cas shrugged his shoulders when Jack looked to him with begging eyes.

"It's okay Jack, I got you a root beer," Sam told him pulling a bottle from his bag.

"Thank you Sam," Jack replied accepting the offering. He was sure it was not the same as their beers, but he was grateful Sam had done this for him.

The travelers arrived at the bunker late afternoon the following day, all tired from the drive. The car was unloaded and Jack headed for his room with his things to drop them off. He came back with his laptop and found Castiel and the brothers in the library.

"Castiel, my Mom left me some videos and she talked about you in one, would you like to see?" he asked sitting is laptop on the table.

"Of course if you want to show me," Castiel replied, interested to see what Kelly said.

Jack opened the laptop and clicked on the folder to open it. He picked the right video and hit play, turning so Castiel could see the screen. Sam and Dean moved where they could see it and listened as Kelly suddenly appeared on the screen and started talking. She talked about herself and hoped Jack grew up healthy and strong. The screen tilted and moved and Castiel filled the screen as Kelly talked to him and he waved to the screen before going back to what he was doing. Kelly told Jack about Castiel and how he had helped them and that he would take care of him when she was gone. She went on to say she trusted him and that Jack should listen to him that he would protect him. Kelly stated that Castiel was to be Jack's guardian and she knew he would raise him right. She said her goodbyes and the screen went blank. No one said anything as they looked at each other.

"She wanted you to be my Dad," Jack said looking hopefully at Castiel.

"I know she wanted me to take care of you and that is what I'm going to do. We talked quiet a bit about it before you were born. We'll all take care of you, Sam and Dean too."

Jack looked to the brothers before answering, "I think I would like that."

"Why don't we go into the other room and talk?" Castiel asked Jack as he got up from the table.

"We'll go get some dinner going," Sam said motioning for Dean to follow him. He wanted to give them some space to talk without ease dropping on them.

Castiel and Jack got comfortable on the couch in the side room before talking.

"Jack, do you know what you are?" Castiel asked him.

"I am a nephilim, my mother is Kelly Kline and my father is Lucifer. I'm half human and half angel," Jack rattled off.

"Do you know what that means?"

Jack frowned as he thought about the question. "I am not sure."

"Lucifer was an archangel and very powerful. You are an unique individual and there has never been anyone like you born before. Some people may be frightened of you because they don't understand you."

"They think because I am Lucifer's son, that I will be bad," Jack stated. "My Mom told me in the last video she made that I didn't have to be bad no matter who my father is. She said I was good and to not believe anyone telling me differently. She loved me very much and died that I could be born."

"Yes she did. Kelly fought to keep you safe. She was a remarkable woman. I will try and train you to control your powers so you will not hurt anyone. Jack can you feel them inside of you?"

"I think so, it seems something is growing stronger inside of me wanting to be set free."

"That is your grace, it's building inside of you. I will show you how to use them safely. We'll start out small like moving that book," he said pointing to a book nearby and moving it into the air and holding it there. He lowered it down and looked to Jack. "Now you try."

Jack looked at the book and tried to lift it. He shook his body slightly and tried again concentrating harder. The cover of the book opened but it didn't move from the table.

"That's good for a first time," Castiel praised him when he saw the look of disappointment on Jack's face.

"You have to remember you are young and still learning. It's not going to happen overnight. We will train every day until you can control them without thinking about it."

"Castiel, is my Mom right? Will I be a good person?"

"I am going to do my best to help you with that. You have your Mom's genes in you and she was a very good person. I think you can be just as good."

"We've got ground beef we can use to make something for dinner," Sam said looking into the fridge. "Or one of us could go get pizza or barbecue."

"Whatever..." Dean mumbled looking into the other room trying to see what they were doing, not really paying attention to him.

"I guess I can fix a large tossed salad with some rolls and we can have some raw vegetables with hummus."

"Wait? What?" Dean asked frowning at his brother. "Hummus my ass, I'm not eating dirt."

"It's ground chick peas not dirt."

"Same difference. Takeout sounds better than having to cook. I vote pizza."

"You want to go or should I?"

"You can, just be careful where you park." Dean tossed him the keys to the Impala. "Do we have beer?"

"Yeah, but I'll pick up another six pack. I'll be back."

Dean watched Sam trudge up the steps before moving closer to the doorway to see Castiel and Jack. He wasn't sure what they were doing since they had quit talking. He saw Cas raise a book off the side table and put it back down and he thought Jack was trying to do the same but only opened it. He guessed using grace had to be learned just like anything else and went to the fridge for a beer since what they were doing was boring to him.
