A/N: I would like to say a big thank you to Coreymon77 who has had the nicest words to say about this story and has also been pimping it out in internet land. Thanks for your support buddy!

This morning began like any other morning since Arwen had arrived at Chuck and Sarah's house. Chuck and Arwen woke up before Sarah, had some breakfast, played some video games, and waited for Sarah to get up. However, this morning when Arwen got up Chuck and Sarah both were already up. As she walked down the hallway they appeared to be having a whispered argument. She really hoped that nothing was truly wrong between them because she wanted this new family they were making to work out. Chuck and Sarah seemed to love each other more than anything, so she wasn't all that worried, just curious.

What Arwen couldn't hear was that Sarah had gotten a call from Casey earlier that morning calling her to Castle for a mission. Chuck was finding staying out of the spy world very difficult now due to the fact that his sister didn't want him to be doing that kind of stuff. What neither of the women knew was that Chuck had been doing his own spy work down in the basement of his old house, just not for the CIA. He was trying to find his mother and would stop at nothing to do that, but he was still itching for the action of being back in the field.

"I want to go with you. You need me," said Chuck.

"No. You're not in the CIA. You can't do this," Sarah replied.

"I'm still the Intersect and I can help. Please, Sarah."

"You can't have this both ways. Either you're in or you're out."

Chuck paused. This wasn't the first time they had had this argument in the recent past. What he wanted didn't align with what Ellie wanted for him. So he had to decide was it better to be out in the world keeping it safe for Ellie, or was it better to be at home where he would be safe, keeping Ellie at peace.

"I'm in. Let's go."

"We need to be at the Orange Orange in 15 minutes to meet Casey at Castle."

Arwen heard this last line perfectly clear. Pretty much everything about it intrigued her. Why would they go to the Orange Orange this early? Wouldn't it be closed right now? What was Castle? Or was it a castle? Casey was involved in all of this? Arwen's mind was spinning. Chuck and Sarah seemed to be involved in something shady. She had been wondering how they could afford this nice apartment. And Sarah had never been honest about what she did specifically. She worked for the government, and that was all Arwen knew. Could she be a spy? Chuck too? No, that was dumb.

Arwen walked out into the living room feigning as though she had just walked out of her room and missed the whole discussion. Chuck and Sarah were packing their things.

"Hey, guys. What are you doing?"

"Crap! Hey, Arwen. We just, uh, have to run some errands today. We'll be back later," said Chuck.

"I can come with you. Wait two minutes," Arwen replied.

"Oh, you know, you probably don't want to come with us. Boring stuff. Why don't you go see what your Uncle Morgan is up to today." Chuck went over and kissed her on the top of the head. "Bye."

"Yeah, bye," she said back.

Arwen put her clothes on and headed across the courtyard to Casey's place where Morgan was staying. She was going to get to the bottom of this.

When she walked in Casey had already gone, but Morgan was still asleep. When she found him in his room she decided a rude awakening was going to be the best way to get him to open up about where Chuck and Sarah were. From the doorway she took a running start. She then proceeded to jump on top of him, remembering she was a full grown teenage girl. Morgan awoke with a scream that was heard around LA. Arwen began to laugh. This was going to be easy.

Seeing that it was Arwen who had pounced upon him, Morgan jumped out of bed, forgetting that he had been, as always, sleeping in the nude. Arwen covered her eyes and buried her face in a pillow.

"Oh my gosh, my eyes!" screamed Arwen.

"What are you even doing hear?" screamed back Morgan.

"I need your help. But first I need you to put on some clothes."

With Morgan momentarily covered, Arwen slipped out of his room to allow him time to change. As she was walking around, she noticed how strange this place was. There was a gun cabinet, nice surveillance equipment, and absolutely no décor save a single bonsai tree. Casey really was a special kind of freak.

Morgan entered the room finally decent.

"So, with that rude entrance you must have something very important to ask me. Shoot."

"Well, I need to know why Chuck and Sarah went to the Orange Orange this morning."

"They told you they were going there?"

"Uh, yeah. They left about ten minutes ago."

"And they left me?" mumbled Morgan.

"What was that?"

"Oh nothing. Uh, I guess they just needed some fro yo to get their morning started right."

"I thought that place didn't open until 11am. It's only 9am right now."

"Ummmm... they... uh... they know somebody. A friend. Who works there."

"Yeah, whatever. Take me there."

"I can't."

"You can and you will."

"Really?"

"Among the skills Chuck and Sarah don't know I have is that, Morgan, I know kung fu."

"Ok, right."

Arwen proceeded to perform a series of kicks and punches into the air to demonstrate her point. She would get what she wanted, even if violence was going to be the way she got it.

Morgan was literally shaking in his shoes.

"Understood. Let's take the herder."

Pleased she got her point across, Arwen skipped out to the car.

Once they had arrived in the parking lot across from the Orange Orange, they both exited the car and walked toward the store.

"Now, Arwen, seriously, you need to just stay on the sidewalk and let me handle this. I'll go see what Chuck and Sarah are up to. I really need you to stay outside. Got it?"

"I'm not stupid Morgan. I understand."

"Okay. Alright. Just do it."

"Yeah, sure."

There was no way that Arwen was going to stay outside while all of the secretive business was going down. So when Morgan opened the door, she snuck in behind him without his knowledge. She was far too good at this. Then Morgan went into the freezer, she caught the door and peered in because the room was too small to follow him. She saw in type in a pass-code on a screen that appeared from nowhere and walk through another hidden door. Arwen slipped through the freezer door quickly enough to slip through the second secret door as well. The sight that greeted her was incredible.

This appeared to be some kind of secret spy lair. She was on top of a metal staircase and down below she saw Chuck, Sarah, and Casey. They were all looking up at her.

"Morgan! What is she doing here?" screamed Chuck.

"Shit! Arwen, I told you to stay outside!" screamed Morgan.

"Yeah, well, I didn't. I surprised you even believed that I would."

Sarah just stood with her head in her hands. This was exactly why having a daughter when you were a spy was a problem. The girl had just walked into danger. Now she knew about Castle, and knowledge made you a target. Her little girl was a target.

Casey was seething. Morgan was such a moron that he couldn't even watch one kid and make sure she didn't go to the one place she shouldn't. What an idiot.

"Get her out of here, now," said Casey.

"No, I want to stay. What is this? What are you guys doing?"

"Arwen, I love you, but you have to go. It isn't safe," said Chuck.

Sarah pondered on how Arwen had gotten in here. She must have been stealthy enough to slip through doors unnoticed. Morgan could have at least seen or heard her if she wasn't good enough. Did this girl, her girl, have the spy gene?
"Let her stay. If she goes, she won't stop asking. She's found us out, we might as well tell her the truth," cut in Sarah.

Arwen continued down the stairs and all five of them sat down at the big metal conference table.

"Arwen, I am an agent of the CIA. I have been since I was 18 years old. That is one of the reasons I never wrote back to you. It would have been too dangerous. This is our base, called Castle."

"I am an agent of the NSA and a former Marine, Colonel John Casey. This base is part of a joint intelligence project. That is where Chuck comes in."

"I am the joint intelligence project, the Intersect. I won't go into details but basically I have all of the nation's secrets in my head as well as the ability to recall special skills, even though I may never have learned them, and perform them no problem. I don't work for the government any more because I want to keep my family safe, but that doesn't change what I have inside my head. The fact that we are telling you all of this means that you are now in incredible danger as we all have been since this began around four years ago. We trust you not to betray our secret. I trust you, Arwen"

Arwen just sat there trying to process for a minute. Then her eyes got big.

"No way! You guys are spies? Awesome! But wait, where does Morgan come in."

"Thank you. I am a new agent of the CIA trained to basically help out Chuck or help find Chuck or just know everything about Chuck.

"This is all pretty wicked, guys."

Just as Arwen was saying that, the teleconference screen popped on and Beckman's face appeared.

"Excuse me, WHO IS THAT?" she yelled.

"Not good. Hello General. This... is... my... my daughter, Arwen," said Sarah.

"You're what?"

"She is actually our daughter General," piped up Chuck.

"Explain, Mr. Bartowski. Then explain what you are doing here as well as the girl."

"First of all, Sarah and I had an anonymous sexual encounter when we were about 16 years old, and that encounter produced a daughter that I never knew existed until just recently. Arwen was adopted by a nice family but is staying with us for a few months. As for why I am here it is because I have decided that I need to be a part of the agency again. It is better for my country and my family that I protect them through active duty than protect myself by staying home. I have no idea why Arwen is in here. It's probably not a good idea."

"I take from what I heard from the girl's mouth that you told her. About everything."

"Yes, ma'am. I did. I'm so sorry, but she would have found out. She is very smart."

"Yes, well, I shouldn't be surprised that you and Agent Walker have created some kind of offspring. I just can't believe that it happened so long ago. Your relationship is getting more and more twisted with each passing day. Now it's time for the girl to go home. Grimes, escort her out."

Sarah knew that Arwen could be an asset to their organization. Yes, there was an element of danger involved, but if they began training her early, they could make her into the best spy this country, and maybe the world, had ever seen. Sarah pushed to the front of the screen.

"If I may, General, Arwen seems to have something special about her. She has a natural spy ability that not many people posses. I think we should groom that while she is here."

"Do you understand how dangerous her life would be if she were a junior agent? Very."

Chuck panicked. He didn't want his daughter in danger. He didn't care if she had talent in this area. She needed to use her other talents. She didn't need to be a baby spy.

"I do understand that general, but putting aside a talent like hers would be the biggest waste."

Beckman thought about it. If she was Sarah's daughter she would be strong, agile, and able to talk her way out of any situation. Being Chuck's daughter she was smart, technologically able, and driven. This child could be a powerful combination.

"I will only allow this to happen if Bartowski give his permission. I need the permission of both parents."

Chuck though about what Beckman and Sarah had said. If he made Arwen stay out of this it would be just like what Ellie did to him. He would be wasting a gift. And he could protect her if she was always near by, and Sarah could too. This could work out.

"Okay, General. Let's do it."

Beckman then beeped out.

"Score!" yelled Arwen.

Chuck, Sarah, and Morgan laughed at her enthusiasm while Casey smirked and grunted.

The next few days included a series of tests for Arwen, each trying to determine her aptitude as a junior spy. The results came back and they were off the charts.

"She has more promise than they have ever seen," said Sarah to Chuck.

"She's you."

"Chuck, that has a lot to do with you too. You are a great spy, and all of that is backed up with the heart to save the world."

"I don't want to save the world, I just want to be with you," he said mimicking a similar statement she had made long ago.

"You can do both, you know?"

"Now we can both be spies together and be with our daughter all at once. I think this is better than the best life I ever imagined."
