Disclaimer- So I know this has been done before, but I wanted to try one for myself. Obviously, it's AU. I'm going to try to make this one a little different, mainly since Dean is the same age as he is on the show, not years older, like he is in most of these kind of stories. So, I hope you enjoy, and please remember to review!

Every time she blinks
She strikes somebody blind
Everything she thinks
Blows her mind
That's my daughter in the water
Who'd have ever thought her?
Who'd have ever thought?
That's my daughter in the water
I lost everytime I fought her
Yea, I lost every time

-Loudon Wainwright III

"Did Bobby say what he wanted?" Dean asked his brother,Sam, as he pulled off the I 10.

"No," Sam said, tuning the radio dial. "He just said it was important and to get there now. I swear, this state has no decent music."

"Is it a job?"

"Dude," Sam sighed. "I just told you that I don't know. If I knew, I would tell you. But I don't."

"All right." Dean beat out a melody on the steering wheel. "You don't have to get snarky."

"Snarky?" Sam raised his eyebrows.

Dean shrugged. "It's my new word. That, and befundled."

"Right." Sam nodded. "Okay."

A few hours later, they were pulling up into Bobby's driveway. He met them at the front door, looking unusally serious.

"I think you guys need to come in and sit down." He said.

"Bobby," Sam asked, following him in. "What's going on?"

"I'll explain...in a minute." He answered.

One of the things Dean loved about Bobby's place was the fact that it never changed...except for the young girl sitting at his kitchen table, eating an apple and reading a book.

"Who is that, Bobby?" He asked. The girl looked up, first at him and then at Sam, her green eyes scanning both of their faces. There was something slightly familiar about her, but Dean couldn't put his finger on it.

"She's part of this, too." Bobby said. He montioned toward his couch. "Sit."

They sat. "What is this about?" Sam asked.

Bobby ran his hand over his face. The girl in the kitchen sifted loudly in her chair, still staying silent.

"Do you guys remember a hunter by the name of Lucas Sinclaire?" Bobby asked. "He had a daughter, Bethany?"

"Yeah," Sam answered. Dean was strangly silent all of a sudden. "We stayed with them one summer, remember Dean? About thirteen years ago, when Dad was on that Lady in White case in Cleveland?"

"I remember." Dean answered. His voice sounded funny.

"That's his granddaughter in the kitchen." Bobby told them. "Addison. She's twelve. Twelve, Dean."

Sam seemed to catch on first. "Oh my God. Dean, you didn't. You and Bethany?"

Dean smiled sheepishly in spite of himself. "All that summer. Why?" He still didn't seem to get it. Sam rolled his eyes and turned back to Bobby.

"Are you saying that the little girl in your kitchen is Dean's child?"

Bobby nodded. "Basically."

Dean jumped up. "What? My child? Are you sure?"

Sam rolled his eyes again. "Dean, look at her. She looks just like you when you were young."

The girl, Addison, had come to stand in the doorway. Dean studied her quickly. She did look like he used to, the same sandy hair, green eyes, the freckles.

"I am your daughter." She told him. "My mother didn't lie."

"Where is she? Your mother?" Dean asked in a strangled voice.

"She died." Addison said simply. "Two years ago. It was breast cancer."

"I'm-I'm sorry." Dean stammered. He sat back down, the force of the news he had just heard finally hitting him. He had a daughter.

Sam turned to Bobby. "I still don't understand. Why is she here?"

"My papa died last week." Addison answered. "He had a heartattack. He told me in the hospital to come here and that this man, Bobby, would take me to my father and my uncle. He said you would take care of me." Her eyes darted back and forth between Dean and Sam. "You will, won't you? I don't have anywhere else to go."

"Of course we will." Sam answered quickly, looking at Dean. "Family sticks together."

"What, we're just gonna take her on the road with us?" Dean asked skeptically. "Take her on hunts?"

"That's what I've been doing the past two years with my papa." She told him, glaring up at him. "I know what to do."

"We'll just let her bounce from school to school, like we did? I wouldn't wish that on anyone."

"I can home-school. Like I've been doing." Addison sighed. "Look, if you don't believe you're my dad-."

"I didn't say that!" Dean interupted. "It's just the road is no place for a kid. Especially a girl. Isn't there someone else who can take you?"

"No," She said. "There isn't."

"Dean," Sam said gently. "We're the only people she has left. What if our dad has just dumped us off on someone else?"

"John never would have done that." Bobby added.

"We could have had normal lives!" Dean shot back.

"Yeah, but it wouldn't have been the same. We wouldn't be the same."

"All right." Dean relented, looking at Addison. "All right. You can come with us."

She smiled for the first time; a big, bright smile that changed her face and finally made her look her age. "Thank you...uh, what should I call you?"

"Let's just stick with Dean for now."

"Dean. Okay. Thank you, Dean."

He forced a smile. "Yeah. Don't mention it."

Several hours later they were on the road again, heading to their original destination of Southern Illinois. It was very late. Dean glanced in the review mirror, at the sleeping form of his daughter. She was laying under a pink fleece blanket, snuggled up to a Tinkerbell pillow. Dean snorted to himself. Tinkerbell.

"I hope this isn't a mistake." He said aloud.

Sam cut his eyes toward him. "Don't you want to know her?"

"Yeah, but I'm afraid she'll get hurt or something."

"She'll be fine." Sam assured him. "We'll just be extra careful, keep an eye on her."

"I guess." Dean didn't feel reassured. "She seems really smart. What did Bobby call her?"

"Precocious." Sam answered. "It means exceptionally smart; ahead of her age."

"I know what it means." Dean snapped, looking back at Addison again. He knew what Sam was saying, but was this the right thing to do?

"Dean," Sam said, almost as if he was reading his mind. "Everything will work out. You'll see."

"I hope you're right."
