This is my first Chicago PD fanfic, so please be nice. I love watching the show so I decided to write a fanfic about it. Hank and Erin's relationship is my favorite part, and I love the father-daughter dynamic.

Thirteen year old Erin Voight was in her room, laying on her bed with a notebook opened up in front of her. She was busying working on her homework, which seemed to be frustrating her at the moment. Glancing over, she looked at her friend Kim's notebook.

"So what did you get for number 8?" Erin asked. Kim looked in her notebook, "Um, hundred forty-seven" she answered.

"Ugh, I came up with two hundred thirty-eight." Erin sighed and fell back into her pillows. "I hate math."

"Me too." Kim agreed.

The two girls continued for the next few minutes to work on their homework. It was quiet until Kim awkwardly glanced up at Erin. "So, um, did you see Adam in biology this morning?" she asked.

"Yeah." Erin answered nonchalantly.

"Uh, yeah. I did too" She said quickly. Erin looked up and gave her friend a suspicious look. "Why?"

A blush started to appear on Kim's face. "No reason."

"Kim?" Erin pressed. "Oh-You like him! You like Ruzek" she gasped.

"NO!"

"Yes!"

"No! I don't" Kim defended, though she did it rather badly. "I don't like Adam, honest!"

"You're lying" Erin giggled.

"Na-huh!" Kim said, her face blushing red. Erin continued to laugh. "Erin!" She exclaimed, grabbing the nearest pillow and chucking it at her.

"What?!" Erin smiled a devious smile. "You love Adam Ruzek!"

Kim narrowed her eyes at her. "Well I know that you like Jay Halstead" she countered. Erin immediately stopped. "No I don't!"

"Yeah you do" and it was Kim's turn to now laugh at the blush that rose on Erin's face.

Erin kicked Kim in the leg. "Let's just get back to our homework, ok?" She didn't want to stay on this subject anymore. At thirteen, it was weird and awkward to talk about boys. It was definitely something that she didn't like to talk about. Though she did like Jay.

"ERIN, DINNER!" Erin heard her mom call. Erin sighed and closed her book. Kim did the same. "I should get going. My grandparents are going over tonight; and blah, blah, blah!" Kim rolled her eyes. Erin laughed and got up from her bed. As the two girls started to walk out of the room, Kim stopped and looked at a picture that was on Erin's dresser.

"Oh hey, you got that picture framed. That was like the best day of my life!" Kim smiled. It was a picture of the two girls in a squad car. District 21 had held a family day the past summer. Hank and Camille had taken Erin and Justin, of course with Hank being on the unit; and Kim had tagged along with. The picture was of Erin and Kim in the front seat of the squad car, with Justin in the back pretending to have been arrested.

"Yeah" Erin agreed, then began to laugh. "It was great how we got to handcuff Justin and throw him in the car! Too bad we had to un-cuff him." Erin loved her little brother and was protective over him as any older sister would be; but man, he could be annoying.

Kim arched one eyebrow and gave her a grin. "Doesn't your dad have an extra pair around here?"

"Burgess!" Erin laughed, pushing her friend.

"Voight!" Kim retaliated, doing the same.

The two girls laughed for a minute before turning their attention back to the picture. "Wow" Kim stated amazed, "Justin looks just like your mom."

"I know, it's kinda creepy" Erin chuckled. Kim giggled and then looked at Erin seriously.

"What?"

"It's just, I'm trying to figure out who you look like. You don't look like your dad or your mom." Kim observed.

"Well Kim, you know the story with that" Erin stated. Kim knew everything about her. The two had become friends in kindergarten when Erin stood up for her. Kim had been getting picked on at recess and Erin just happened to be by the same slide. The five year old watched as the boy picked on Kim and after a few minutes, she'd had enough. Her daddy had taught her to stand up for people. So going over to that boy, Erin pushed him to the ground, yelling "You leave Kim alone or you're gonna deal with ME! And my daddy can arrest you TOO!"

The girls became friends that day and had been inseparable since. And when Erin got home that night, her dad smiled with pride at his little girl.

"So you've really never met your real mom?" Kim asked, looking at the picture.

Erin shook her head, "Nope."

"Wow!" Kim placed the picture frame back on the dresser. She turned and looked at Erin, "Do you know anything about her?"

"No, nothing. All my parents has ever said was that she left when I was a baby." Erin said.

"Have you ever asked your dad about her?" Kim asked.

"Not really" Erin answered honestly. Truth be told, she never really cared about her biological mother. Yeah she had wondered from time to time, but it never really mattered to her.

"Well, all I know is that if I didn't live with my mom, I would want to know about her and know about everything that happened" Kim stated. She left it at that as she left room.

Camille was standing at the bottom of the steps, getting ready to call her daughter again when the girls finally made their way down the steps. "Oh, I was just getting ready to call for you again." Camille smiled at Erin, then she turned her attention to Kim, "Hi Kim."

"Hello Mrs. Voight" Kim said politely.

Camille rolled her eyes. "Kim, how many times do I have to say that you can call me Camille" she smiled. Camille had known the little girl close to eight years now.

"Oh sorry" Kim said meekly.

"So what were you girls doing?"

"Homework!" Both Erin and Kim answered in the same disgusted tone. Camille laughed. "Oh, that dreaded subject, huh?"

"Yes, and we had a huge test in Mr. Adams's class yesterday and he loaded us with homework today." Erin said with as much injustice as she could. "You'd think that we'd get one day off!"

"Well seventh grade's tough like that, kid" Camille said understandingly, as she tousled her daughter's hair. "But hopefully your favorite dinner can cheer you up." Erin smiled, "Pizza?!"

"Ah-huh." Camille confirmed, nodding her head. "Your dad's picking it up on his way home from getting Justin at baseball practice." She explained, then looked over at Kim. "Oh Kim, you're more than welcome to stay for dinner."

"Thanks Mrs. Voight, but I can't" Kim said, forgetting Camille's earlier remarks. "My grandparents are coming over for dinner. I can basically tell you how the whole night will go. My mom will be crazy, going around the house trying to clean everything even though the house is spotless. And my grandpa is going to be complaining that my dad should've stayed in the family business, and that he could have provided better for us if he did" She rambled.

Both Camille and Erin were chuckling by Kim's rambling. "Oh well, I gotta go Erin. Pray for me" Kim pouted a little.

"I will. Bye Burgess" Erin said to her, as Kim opened the door.

Kim walked out the door. "Bye Voight."

"Bye Kimberly" Camille smiled, shutting the door. She turned back to Erin. "Why do you guys called each other by your last names?"

Erin shrugged, walking into the kitchen. "Dad does with his partner." She answered. "And when we're older, Kim and I are going to be partners. We already have it planned out, we're going to working in the same unit and everything!"

Camille rolled her eyes. She should have known. Erin was a mini Hank Voight. She had inherited everything from the man. The way she thought, the way she acted, and the quick temper she had. Erin had a lot of spunk and definitely had a mouth.

"So are you going to work in your dads unit?" Camille asked, handing her a pile of plates for the table.

"No!" She grabbed the plates from her mom, "I already have to listen to dad at home. Why would I want him to be my commanding officer at work?" She asked incredulously.

"My apologies" Camille said with a chuckle. Erin smiled and continued setting the table.

"So you and Kim rushed up stairs so fast I didn't even get to ask you how school was today?" Camille questioned. Erin slowly put a plate of the table. "Uh, well…it was ok"

"Erin" Camille read right through it. "Go get it"

Erin looked at her confused. "Get what?"

"The test that I need to sign." Camille answered point-blank, causing Erin's mouth to drop in shock. "B-but how…?"

Camille laughed, "Because I'm a mom. Now go grab it so I can sign it before you father gets home."

Erin nodded and went to retrieve the test. Grabbing it, she returned to her mom. "Mom, I'm sorry. Math is just so hard" Erin explained quickly when she saw her mom's face.

"Erin, this is the third test in a row" Camille scolded.

"I know, but I am trying" she defended. Camille looked at her and sighed. "Ok, Erin" she conceded, grabbing a pen to sign it. "But if you bring home one more failed test in this class, you're getting a tutor or some kind of help. You can't keep bring home these kind of grades." She threatened, signing it.

"Thank you" Erin smiled, taking the paper from her. "Um, you-your not going to tell dad, right?" she asked nervously.

"No." Camille assured, "Erin, they are just some things that Hank Voight doesn't need to know. This is one of them. Right now it's between you and me, but-" she stopped when she saw Erin smirk, "If you bring home another test like this, I will tell him. Understand?"

"Yes mom" Erin nodded. She turned and went to put the test back in her backpack, and as she was zipping the bag; the front door opened. Perfect timing!

"Cami, I'm home" Hank called out. "Justin, shoes and backpack in the closet" Erin heard him instructed to Justin. Her brother always forgot to put his stuff away.

Hank came into the kitchen, carrying a pizza box. "Hey Cami" he smiled, going over and giving his wife a kiss.

"Gross" Erin muttered under her breath. Old people kissing just grossed her out.

Hank and Camille turned their head towards her. Camille smiled, while Hank smirked. "What's gross about this?" he asked.

"Old people kissing" Erin answered, shivering. Hank and Camille both laughed. "You think we're old?" he asked.

"Yeah. Anyone over fifty is old" Erin put it simply.

Camille gave an outraged face, "I am not over fifty, young lady. I'm still in my thirties, thank you very much!"

"Still old to me" Erin shrugged, giving a mischievous smile.

Hank glanced over to Camille, "I guess we're old, Cam." He stated, his tone loving.

"Oh, I guess we are." She smiled, placing her hand behind his neck and giving him another kiss.

Hank in return dipped Camille back and gave her a kiss, as Justin came into the kitchen. "Eww, Gross!" The eight-year-old exclaimed. Hank smiled and Camille giggled. The best part of being parents was being able to gross your kids out.

"Cover your eyes Justin, this might get graphic" Erin warned. Both adults laughed again. "Ok, Hank" Camille cued, and Hank raised her back up.

"Hey bud, how was practice?" Camille asked to her son.

"It was great, mommy. My coach said that I'm one of his best players" Justin beamed.

"Well that's great, Justin" she smiled. Camille then grabbed the pizza box from off the counter and started walking towards the table, giving Erin a light swat to her bottom in the process. "And I am not old, young lady" Camille just wanted to put that out there.

Erin laughed and followed her to the table.

Dinner was a happy affair. Everyone talked about things that went on in their day. Camille insisted that every night the family come together for dinner. That's how she was raised and said that it helped strengthen the family bond.

"Oh, did I tell you that I talked with my mother today" Camille began. Hank grimaced a little. He wasn't particularly fond of his mother-in-law, but he put up with her for Camille.

Camille continued, "She said that she is wanting to come to Chicago and visit us. So we talked about dates she could come up."

"So when's grandma coming?" Justin asked.

Erin was happy to hear that her grandma was coming. She always spoiled her and Justin was stuff. But suddenly, the thought came to her that her grandma wasn't her real grandma. It was her mom's mom, so she technically wasn't blood related to her. She had another grandma on her biological mother's side that she didn't even know about. Heck, she didn't even know about her real mother.

Erin looked at her pizza, suddenly not hungry. Her mind was thinking about the conversation earlier, the one she had with Kim. Erin was beginning to seriously think about her biological mother. Who was she? Why didn't she know anything about her? Everyone knew about their biological parents, why didn't she?

Erin glanced up at her dad. "So um, what can you tell me about my mother, my biological mother" Erin asked. Hank questioned caught him by surprise. "What do you want to know about Bunny for?" he asked, his voice gruff.

"Bunny?" Erin repeated confused. She'd never heard that name before.

"Barbara." He corrected. He didn't need Erin knowing her mother's street name. He didn't even want Erin to know about her at all. "What do you want to know?" he asked.

"I don't know." Erin shrugged, "I guess I just wanna know who she was. Why she left me?"

"Erin" Hank sighed. He really didn't want to have this conversation right now. Especially in front of his other kid. "I already told you about all that."

"Not really!" Erin scoffed, "Dad you just said how she left when I was a baby, and that her name was Barbara."

"And that's all you need to know." Hank stated. There was no way that he was telling Erin more. He didn't want her to end up like Bunny. Hell would freeze over before that happened.

"Hank." Camille interjected softly. Her husband was being unreasonable and he knew it.

Erin huffed hotly. "I deserve to know more than that. I just want to know some stuff about her." She defended.

"Ok" Hank said softly, as softly as his grave voice would allow. "Look kid. One day when you're older, I'll tell you, ok. Everything you want to know."

"Dad, you're treating me like a kid!" Erin exclaimed. She was thirteen for crying out loud. That was practically an adult. "I'm old enough to know now."

Hank shook his head, "Not in my book."

"Well your book is wrong" Erin sassed, anger taking hold of her. "It's my right to know. She's my real mom."

"Erin" Hank warned. He wasn't liking the tone that his daughter was taking with him. "That's enough. The subjects closed. We'll talk about this later. "

Erin glared at him, stewing with anger. "Ugh!" she seethed, and standing up she pushed her chair back with force and started stomping out of the room. She knew better than to yell at her dad. It was better to walk away.

"Erin!" Hank called after her. He started getting up when Camille stopped him. "Henry!" she warned, giving him 'the look'.

"Camille"

"Hank, don't" Camille said, "You're being unreasonable and you know it. Let her go up to her room and be angry. If you go up there, you two are just going to get into a screaming match with each other and that won't help anything."

Hank took a deep breath after she had finished. Camille was right.

"Now sit down and finish eating. Justin is still sitting here" she smiled when she looked over at her son, "And I'm sure there more he wants to tell us more about his day, right Justin?"

Justin nodded, "Ah-huh daddy. I didn't even tell you what else my coach said" Hank smirked at his son. He didn't want Justin to know anything about what was going on with Erin. Just was eight and didn't need to know things like that.

The next day after school, Erin couldn't stop thinking about what Kim said. She had been stewing in her room after dinner last night and her anger hadn't dissipated. She hadn't been able to concentrate at school and her mind was fixated on it. When she had gotten home, she went up to her room with the intention of starting on her homework; but that didn't happened. Curiosity had gotten the better of her and she desperately wanted to know who her mom was. She knew her dad wouldn't tell her, so she had the next option; finding out for herself.

She got off her bed, and walked out of her room. After tiptoeing down the stairs, did a quick search of the hallway as she quietly made her way to her dad's office. She knew her mom was outside in the yard and that her brother Justin was upstairs playing with his toy helicopter; so she knew that she had some time.

Erin put her hand on the door knob, but hesitated. It was a big rule in the Voight house that she and her brother were forbidden to go into her dad's office if he wasn't in there or if they didn't have special permission. Erin didn't know why the dumb rule was in place. It wasn't like a special field OP was going on in there!

But she needed to do this, she needed to know who her real mom was. She couldn't understand why her dad wouldn't give her the answers. It was stupid! Taking a deep breath, she turned the knob. She needed this answers and she was going to find them…

Some feedback for this story would be great!
