Danny looked through the door at the young man in the locker room. He had been walking through the precinct when he heard someone mention the new rookie looked kind of like Joe Reagan. Danny almost froze but continued walking, changing his course to go by the locker room, and pushing down the hope that it could possibly be who he wanted it to be. Shock ran through him as he caught sight of the rookie, the kid looked like Joe, like his mother, and heck Danny could even see their grandfather in the guy. Danny grabbed a passing patrol officer and motioned towards the rookie with his head, "Who's the kid?"

The officer looked at the young man before answering, "New rookie, Jamie Collins. Heard the guy was top of his class at the academy."

Danny silently thanked the officer as he walked away, and spared another moment to capture a photo of Jamie before rushing off to 1PP. Garret looked surprised to see him as he approached the Commissioner's office, "Danny, what are you doing here? I didn't think you had any cases at the moment to consult the Commissioner about."

Danny walked up to the man and placed a hand on his shoulder, "No but I think I found him."

Garret's eyes widened, "Are you sure?"

Danny nodded, "The kid looks like…well all of us. Anyways, I got to see him, anyone in there?"

Garret shook his head, "Just Erin, she came by to talk about Nikki."

Danny smiled, "Perfect." The detective patted Garret's shoulder and walked into the Commissioner's office, startling his sister with his entrance.

Erin scowled, "Danny! We were having a serious discussion."

Danny dismissed her comment with a wave of his hand, "Doesn't matter."

Erin looked affronted and Frank turned to Danny, "What is it?" Danny pulled out his phone and thumbed to the picture before placing it in front of his father. Frank looked at the photo, his eyes widening and shooting up to look at his son, "Is that…"

Danny nodded his head before his father could finish the sentence, "I think so."

Frank looked back to the photo, "And he's a cop?"

Danny's smile widened, "Yep, in my precinct too."

Erin looked between the two men confused, "Who's a cop in Danny's precinct?"

Danny looked to his sister, "Jamie." Erin gasped, her hand flying to her mouth.

Frank stared at the photo as he asked, "Are we sure it's him though?"

Danny shrugged, "No but the kids name is Jamie, Jamie Collins. He was top of his class apparently and he looks just like Mom, and Joe."

Erin lunged and grabbed the phone, her eyes collecting every detail of the man in the picture. Erin saw what her brother meant and her eyes filled with tears, "Dad, can you find out? Maybe check his prints against the ones you had from when he was a kid?"

Frank paused a moment, "It would have shown up on the background check. He might not be Jamie."

Danny snorted, "Did you not see the kid? It has to be Jamie!"

The Commissioner sighed, "Then his finger prints have been altered some way. It wouldn't help to compare them."

Erin's eyebrows rose, "Is that even possible?"

Danny nodded his head, frowning, "If there was enough damage done to the finger pads they could change. Scars or callouses can form and create voids in the print, changing it enough that it would no longer show up as a viable match to the original print. It happens sometimes with certain hobbies, or with prisoners of war, makes it harder to identify the soldier if he dies."

Erin blanched at the implications then sighed in defeat, "Then how will we find out?"

Frank turned to Danny, "If you can get him to voluntarily submit to a DNA test we could run it against ours, see if there is a familial match."

Danny ran a hand through is short hair, "I don't know if I could get the kid to do it, I've never even spoken to him before."

Erin reached out and grabbed her brother's wrist, "You can figure out a way. You have to do it."

Danny nodded, "I'll try. Right now I just have to get the kid to talk to me." Danny turned to leave, pausing as he hit the door, "Just, don't tell anyone until we get confirmation, I don't want them to get their hopes up only for it to turn out the guy isn't our Jamie."

Erin nodded, "My lips are sealed."

Frank looked down, "I don't like it but I agree it might be for the best."

Danny sighed as he got up and said his goodbyes and headed back to work. He wasn't sure what to do if he saw the man again, he so desperately wanted the kid to be his long lost brother who had been taken from them so long ago but he didn't want to be let down again. Danny was so lost in his thoughts he didn't notice the man in front of him until he ran into him. The young officer turned around and Danny thought it was just his luck that it was Collins.

Jamie's face paled a second, "I'm so sorry Detective Reagan, I should have been paying better attention."

Danny shook his head, "Nah kid, it's fine, it was my fault. Officer Jamie Collins, right?"

Jamie nodded, "Yes sir."

Danny smiled, "Who is your TO?"

Jamie looked a bit nervous as he answered, "Sergeant Renzulli, Sir."

Danny laughed, "No need for the sir, call me Danny or if you have to, Reagan."

s head was nodding so much he looked like a bobble head doll, "

Danny laughed again, "It's fine kid, I don't bite."

Jamie huffed, "Not what I heard." Jamie's eyes widened in surprise at his own words, as if he hadn't meant to speak them aloud.

Danny laughed harder, "I like you kid, tell you what, to apologize for running into you earlier, I'll buy you a beer and let you grill me on what it's like to be a cop in this crazy city." Jamie hadn't been expecting that, then again everyone always said Danny Reagan was a strange one. Not trusting his voice to betray him again, Jamie nodded, making Danny's smile go wide, "Alright kid, meet me at the cop bar around the corner after you get off shift." Jamie nodded again and watched as Danny walked off, wondering what in the world had just happened. Danny, on the other hand, couldn't believe his luck. He now had the perfect opportunity to talk to the kid and find out a few things and maybe talk him into testing his DNA. Danny smiled, thinking for once, it might actually be real and he would have his baby brother back.
