Author's note: This is my little AU idea. I love Young Justice and I am a huge Superman fan, but I hate how cold he is in the series. I think it is ooc for him and I'd like to see that relationship change. This story is just a take on how that could happen if Clark Kent already had a daughter and she joined Young Justice.

Chapter One

Her purple painted fingernails sped across the keyboard as she worked to finish her report. She heard the familiar "whoosh" of her father entering the house through the open bedroom door. She stopped and waved a little smoke from her keyboard, she guessed she was going a little too fast. She had gotten the message earlier that her father was still unreceptive to the "situation." She had been waiting patiently and now it was her turn to put her plan into action.

Clark made his way down the stairs after changing out of his suit. He had done a couple rescuers after that "talk "with Bruce. He had needed to get his mind off of it.

"Dad." Clark heard the voice of his daughter. There was something in her voice that he hadn't heard before. Her voice was laced with something; it wasn't anger, but something close. She saw his thirteen year old daughter at the bottom of the steps with her arms folded in front of her. He got to the bottom of the steps and looked into her blue eye, and then he knew, it was disappointment.

"Why didn't you tell me I had a brother?"

"How…" He trailed off, he knew how she knew, damn Dick Grayson. Between Bruce and his ward he wasn't going to able to ignore this "situation."

"Where is your mother?" He asked. He silently, hoped she hadn't told Lois.

"She's working, don't worry I didn't tell her… yet."

"Listen Caelyn, I don't know what Dick told you, but…."

" But what? You didn't want me or mom or grandma and grandpa to know that his boy existed and you have no intention of dealing with him? What were you going to do, just dump him on the Justice League and think no one was going to find out?" She raised her eyebrow. He sighed, she was so straight forward, so much like her mother, maybe too much for his sake.

"Please just let me say something," he said and looked at her to see if she would let him continue. He led her to the couch and sat them both down.

"This is all just so disconcerting. Do you understand how he got here? He was created from my DNA. They stole it somehow. He was created as a weapon, probably to use against me. I just don't know how I'm supposed to react." He said, finally letting himself vent.

"Well is ignoring him the right thing to do?" She asked honestly, there wasn't any sarcasm in her words.

"He probably feels scared and alone, but he isn't alone. He doesn't have to feel that way. We can help him can't we? "

"I don't know what he is capable of. Batman says he has a lot of anger."

And Robin says he is a good guy. He just needs help from people like him, he needs us."

"When did you get so insightful?" he asked honestly. She just smiled in response. It seemed like just yesterday she was his little girl, but their conversation was showing how much she was growing up.

"So what are we going to do?" she asked

"I'm being honest here. I don't know how this is going to work out. I'm just trying to adjust to all this. I just need more time."

"Okay," she said slowly. "Then I have an idea." Clark didn't miss how her eyes lit up a bit. He let her continue, not sure where his daughter was headed.

"You let me join the new team and in exchange I will give you another month to adjust before I tell anyone." Clark's mouth fell open slightly, was his daughter blackmailing him?

"Wait. This isn't fair. Caelyn your too young, your powers…." She cut him off

"Dick is the same age and my powers have been developing since I was a baby. Mom told me stories about how I'd float out of my crib. I want to do what you do. I want to be a hero like you someday and this is the perfect way for me to train. I can learn so much." Her eyes were pleading a bit, but she also knew she had the upper hand.

"You are not making this any easier on me Cael, you do realize that don't you?" he said as he let his head go back and hit the pillows of the couch.

Caelyn giggled a bit over her victory, but then got up and hugged her father.

"It is all going to be okay, daddy," she whispered.

Dick got her message. He went to Bruce's' study and opened the door.

He smiled wide and said only, "Plan B for Operation Super Dad is complete. We have a supergirl."

The team (Atriums is not on the team yet) was gathered in the main hall of Mount Justice. They were told they were going to be introduced to someone. Robin was forcing down his smile, as to not give it away.

The zeta tubes announced the arrival of the visitor, Batman 02, Supergirl B 07." Superboy's eyes went wide with the announcement of the second person. He say her appear. She had on a uniform similar to Superman's, but it included a skirt, short sleeves and a shorter cape. She stood next to Batman smiling, then she saw him. Their identical blue eyes met and locked. The boy quickly turned angry, it was an easy emotion for him.

"What is this? Did he do this? Who is she, my replacement?" He yelled. The rest of team seemed shocked, Caelyn stepped forward.

"No, I'm you sister," she stated simply. Superboy's eyes went wide again.

Just a note- If you haven't figured it out, Caelyn know the identities of Robin and Batman, more of that backstory to come.
