"Reagan," Danny said, picking up his phone. He looked over at Jackie, who in turn looked back at him and tilted her head. They were tied up with a case about two teenagers being shot in the middle of a bar and they had absolutely nothing.

"Detective Reagan. I need a favor,"

"How can I help you Commissioner?" Danny said, leaning back on his chair. Jackie turned to look at her computer, and continued looking into their case.

"I need you to get every file that you can on a Lizzie Marie Johnson. She's lived in Chicago all of her life and claims her grandmother knows me, but she said there were some precautions put into place so she couldn't know much about her grandmother."

"On which side?"

"She doesn't know that either. She just says she used to go visit her all of the time when she was little until she died. Danny, her parents are dead. She watched them get killed."

"Commissioner, why don't you do this yourself?" Danny said, shifting to start looking at the computer.

"I'm going out," Frank said, smiling at Lizzie. "Besides, I want you to do it. See what you can get from Chicago PD and get anything you can on this girl's family."

"Will do. Jack and I'll be right on it." Danny dropped his phone and put in the search for Lizzie Marie Johnson. Apart from the fact that there were thousands, he was able to narrow it down to just five with the right age group in Chicago.

"What'd the Commissioner want?" Jackie asked, leaning forward to take a sip of her coffee.

"Needs me to look into this girl that showed up in his office. It must mean a lot to him if he asked me to do it."

"What's the name?"

"Elizabeth Johnson with parents Melissa and Chad."

"Yup. They were definitely murdered alright." Danny walked over to Jackie's side of the desk to see what she was pointing at. He saw the pictures of the father and mother, lying on the floor after being stabbed to death.

"Poor girl had to see this happen to her parents. No wonder she's traumatized."

"But what does she have to do with the Commissioner?"

"No idea. Said her grandmother knew him."

"Melissa was a middle school teacher and her parents are both in prison for battery charges in California and have been there for a while. Chad is a lawyer and both of his parents are dead."

"Who could she be talking about then?" Daniel questioned, waiting for either himself or Jackie to figure it out.

"Maybe she's adopted," the both of them said aloud simultaneously. Jackie continued looking through files. "Aha!" Jackie declared, pulling up a file, until being blocked by a login screen. Jackie fumbled with the keys putting in her ID, but the big red letters reading ACCESS DENIED shined in her face.

"Let me try." Danny said, putting in his credentials. He too was met with the access denied screen.

"What do we do now? We need a higher up to get in," Jackie gave Danny the look.

"No Jack, I'm not asking my father to get the file for me."

"Reagan he asked you for the favor and all you're trying to do is do it for him. There's nothing wrong with asking him for help."

Danny scoffed. "Fine. But I'm going to wait until the rest of the files get shipped over here."

Lizzie Johnson was a lot of things. She was sweet, smart, charismatic, and able to handle anything. If you asked her how she felt about sitting in Times Square with the Police Commissioner of New York City sipping a Starbucks frap, she would tell you she was absolutely terrified.

"Lizzie- tell me more about yourself."

"I love singing- I'm in showchoir, was in showchoir. I love acting, dancing, singing. But I was planning to go to college to become a lawyer. I don't know- watching them on TV always came close to my heart for some reason."

"And did you submit to any colleges?"

"I did. I'm in senior year. I've been thinking about it a lot. I wanted to originally study in New York, but my parents said it was too expensive. I love this city so much. I fell in love with it when I came here freshman year with my choir and we performed in Carnegie Hall."

"New York is a great city." The Commissioner agreed.

"Yeah. I remember after the performance I walked outside and gave my mom a hug and thanked her for letting me come here. It certainly wasn't the cheapest trip." Lizzie looked down, the sadness evident in her face.

"I have one of my top detectives working on the case. And your grandmother- she is real right?"

"I swear she's a real person. I know I sound like a crazy person because I can't tell you her last name, but she just... she was so sweet. There was something about her though that I cannot quite figure out. She was always so... protective of me. Like she was afraid I would break."

"That's what all parents do for their children."

"I know... but she was different. I don't know. Maybe I'm crazy. I just- I know I'm a legal adult and all of that, but my parents are never going to see me graduate high school or college or get married and have kids!" She started sniffling again. The commissioner again felt awkward with the situation, but since she reminded him of Nicky, he proceeded as would have with her.

"Things happen that we cannot control. These things can sometimes hurt us. The challenge is not to be strong when they happen but to be strong enough to rise above them and move on."

"That was good ." Lizzie nodded in agreement, wiping the tears off her cheeks, flushed with embarrassment that she had cried in front of the New York City Police Commissioner, twice.

The commissioner picked up his ringing phone, holding it to his ear.

"Danny is here. He has some files for you. Says he needs to talk to you."

"Alright. I'll be there."

"Danny what have you got for me? Detective, this is Lizzie Johnson, Lizzie this is Detective Reagan of the NYPD."

Lizzie waved nervously at the detective. Was it a coincidence that the both of them had the same last name? Or were they related?

Cop families must be weird.

"The CPD has been investigating, interrogating neighbors and friends of the Johnsons. But they've come up empty." Danny looked up at Lizzie. "Did they interrogate you? You're the prime witness."

"Except that I ran off and everyone thinks that I am dead. I don't have any relatives that aren't in jail or alive." Danny felt a stab at his chest. He couldn't imagine Jack or Sean not having any family to go to if he died. He couldn't imagine that. His family was too close.

"Was the man someone you knew?"

"No. But it felt like I should've known him the way he was talking to me. Said he was my father and that soon our family would be reunited."

"Are you adopted?" Danny bluntly asked. He knew that finding out you're adopted, not to mention after her parents were murdered right in front of her, hurt.

Lizzie slumped back in her chair, pouting slightly. "I guess it's possible. That would explain why this grandma lady wasn't related to either of my parents. Maybe she was my birth grandmother and my key to answers. And she's dead."

"Her name was Mary." Frank added, knowing that it would remind him of the same thing it did him. Their Mary, Danny and Erin and Jamie and Joe's mother, was the one who knew them all best. But she was gone too.

Danny pulled out another file from the stack. Opening this one showed the file of Lizzie Johnson. It said she was born September 14, 1992 and her parents were Melissa and Chad... as he continued flipping he saw nothing out of the ordinary... she was a great student...

Danny sighed. Those files that were locked probably contained something that could help them. Sighing, he debated asking his father for the password, but then his father cut him off.

"We'll get her police protection, just until we find out who this guy is. If he really is after her, he might have followed her to New York. And I will not have a girl that just lost her parents die in my city under my watch." Frank declared. "I know a lot of people that look to me to protect them, and this girl clearly falls under that category."

"Where are we going to take her though? It's not like we can take her home with us." Danny asked, knowing that she would be dropped off at the shelter tonight.

"Maybe we could leave her with Jamie. Sydney's gone now." Danny asked, really not wanting to drop off an eighteen year old girl that was now alone with a bunch of strangers when a lot of them were men. Besides, something just came to his mind, something that he needed time to do. He had a gut feeling, and his gut feelings were never wrong.

This girl that stared back at him looked just like Erin. His kid sister Erin, the one he fought with all the time when they were kids. But she was also his best friend and he knew that this girl was Erin.

"Danny we can't just leave a stranger with Jamie. That's against protocol."

"But Jamie is a cop, and she needs police protection. Okay, so maybe that is a really weird idea. Just please don't make me take her to the shelter." Danny begged. Frank tilted his head at him.

"I wasn't going to suggest that you take her to the shelter. I was going to suggest you take her with you back to the station and give your witness stand."

"Then what?" Danny asked, not sure where his father was going with this.

"We'll worry about that when the time comes. For now, we'll just treat this like any other case."

"We'll treat this like any other case? Are you saying that this kid who came halfway across the country to find you is nothing but a case to you?" Danny raged, getting irritated at his father's lack of concern.

"Detective Reagan-" Lizzie started but was then cut off by the PC.

"I didn't mean it like that Danny. There just isn't that much we can do.. And we would of course do all that we can..."

"And we will, because this case just took top priority for me.." Danny growled. "Let's go Lizzie..." Danny bolted out the door. Lizzie looked back at the Commissioner and he nodded, leaving her to go follow that crazy Detective Reagan.

Danny motioned for Lizzie to get in his car on the passenger side, and Lizzie obliged without saying anything, mainly because he looked really mad. Lizzie debated what she was going to say to him, she knew she needed to say something, but...

"Detective Reagan, I appreciate your defense of me, but you really didn't need to-"

"Look, you clearly had a reason for driving to New York to see my father. He cares about every single person in his city, but he has a lot on his mind right now. I'm the kind of person that doesn't stop until they get results."

"I can see that," Lizzie laughed.

"Can I ask you something?" Danny asked.

"Yeah..."

"Those bruises on your face?"

"Oh.." Lizzie didn't want to, but suddenly it felt like she was reliving the whole thing all over again. She gripped the edge of the seat as if it was her lifeline.

"I'm taking you to the hospital..." Danny started.

"No no no please no," Lizzie begged.

"Relax, I know someone there..."

"Hi Danny," Linda said when she saw him and a teenager girl walking through the hallway of the hospital. He had sent her a text saying he would show up but she was not expecting a teenager girl.

"Is your face okay?" The woman asked, now standing in front of her. She had short blonde hair and a look of concern of her face. and then Lizzie realized that the bruises from her fight with the murderer of her parents were still showing on her face. Between the Commissioner and Danny , no one had thought to clean the bruises. They were too concerned with trying to find out how she was connected to the Reagans, despite her lack of knowledge.

"Let me clean it up for you. I'm a nurse. C'mon," The blonde said. Danny walked over to her, leaning his mouth towards her ear.

"Get a DNA sample for me, and I'm not sure about possible rape...?" Linda nodded and then motioned at the girl, plopped down in one of the seats.

Lizzie hesitated, looking over at Danny for approval, and after he nodded she rose to follow the blonde. Once they went up to the ER, the blonde motioned for her to sit on the seat, and after fishing around she pulled out the first aid kit and started to work.

"I'm Linda by the way. I'm Danny's wife."

"I'm Lizzie." She bluntly responded, a little tired of being thrown around.

"Danny told me about you. I can't imagine you're having an easy time adjusting to finding out you're adopted, let alone the possibility of your birth father being involved. And losing your parents... I'm sorry kid." They stayed together in silence, Linda dabbing at the gashes on her face with an antiseptic before bandaging them.

"I know this is touchy, but I need to ask..."

"I was not raped." Lizzie declared.

"That's a good thing. And I need a sample of your DNA..." Linda grabbed a swab from the cabinet.

"I was bruised in the face, what does that have to do with my DNA?"

"It's a standard procedure." Linda said, putting the swab in her mouth. "Stay here." She said, wondering away to get the DNA processed for Danny. She didn't really know where he was going with this, but she supposed she should trust him.

"Good as new."

"Thank you." Lizzie said, getting off the counter.

"If you ever need anything, Danny or I are always a phone call away. Don't hesitate to call us, even if it's at three in the morning. We'll make time for you, you're important to us whether you like it or not."

"Thanks... Dr. Reagan?" She said in a questioning tone, tilting her head.

"I'm not a doctor, but thanks..." She said, slinging an arm around Lizzie. Lizzie snuggled into the embrace. But she was not going to cry. Not again. The two of them walked back to where Danny was sitting. He saw the two of them and got up.

"I need you to stay with Linda." Danny said, walking towards the door.

"Where are you going?" Linda asked, irritated her husband was just taking off.

"I need to go see Erin," He said before slamming the door behind him.
