The ride back to Chicago was the complete opposite from the ride to the hotel, both kids were wide awake and neither was very happy.

Harleigh had done nothing but cry which had Diesel in tears, he had thrown up his morning bottle and bucked any of Kim's attempts to soothe him

Harleigh had set the tone for the day and it had left both Adam and Kim on edge.

Adam applied a bit more pressure to the accelerator, they were about thirty minutes out of the city and while they had made good time they were arriving at the worst time possible and were destined to hit traffic.

Hank had received a text message from Kim that had included photos of the kids with what little they knew about them. He printed the photos off and stuck them to the whiteboard.

He addressed the team, "You're looking at Harleigh and Diesel. Harleigh is five and we're guessing Diesel is between five to seven moths old, Burgess seems to think he's six months old. They were found in the house, she and Ruzek were investigating. Alone."

"Shit." Atwater muttered, "I guess it was a smart move checking it out." He kept his eyes focused on the whiteboard and Voight but he hoped his comment had resonated with Upton. He knew it was a bit petty of him but he got some satisfaction out of knowing that Upton had been proven wrong.

Hank shook his head silencing Upton's retort, "Don't." He glared at her, "I've been texting back and forth with Burgess all morning, they're on their way. Should arrive in the next hour or so depending on traffic and the condition of the roads."

"Where are the kids parents?" Halstead asked, "Are we sure they're involved in our case?"

"At this point? Your guess is as good as mine. I think we need to play it as if they are, we've got to figure out who they are and where they are. I don't want anyone outside of this unit to know that we've got the kids in our custody."

"Shouldn't we turn them over to DFACS?" Upton asked, "put them in protective custody?"

Hank curled his lip, "No. They're perfectly safe in our custody." He told her, "We can use them to our advantage, we find their parents and flip them. Right now, that's our main objective, we need to find their parents."

"I want mommy!" Harleigh shouted from the back seat, she had stopped crying but her chest was still heaving, her face was blotchy and tear stained.

"I know sweetie. We will get this sorted out and you'll see your mommy soon." Kim told her, though she wasn't sure that was the right thing to tell the kid. She had no idea when she'd see her mother or if she'd get the chance to see her.

Adam stole a quick glance at her, they locked eyes and Kim shrugged her shoulders.

They both knew how complicated the situation was.

Adam pulled into the back of the district parking lot, they'd been told to use the backdoor the fewer people that saw the children the better.

The entire situation left Kim feeling uneasy but she had to trust her boss and the team to do the right by the kids.

Adam had called Kevin as soon as they arrived and he alerted the rest of the team that they'd be coming upstairs momentarily.

"Alright, let's settle down." Voight instructed them, "This is an unusual situation, I don't want these kids scared anymore than they already are. Cover your service weapons if possible and give them space."

Harleigh held tightly to Kim's hand as they walked upstairs, Diesel out cold in Adam's arms.

"What's this place?" Harleigh looked up at Kim.

"It's the police station. Adam and I work here. We are going to talk to our friends and they will help us find your mom and dad."

Adam went into the bullpen first, "Hey..."

Kevin jumped up, "This is wild."

"No kidding." Adam adjusted a now awake Diesel on his hip, "It's fucking nuts. This dude is a cakewalk his sister...she's a pistol. She's also pretty pissed off at the moment. Tread lightly."

"Will do." Kevin looked down the hall, "Where is Burgess?"

"She told Harleigh she could get some candy from the vending machine, they should be up shortly." Adam explained, "What's the plan?"

"Not sure." Kevin followed Adam towards the break room, "Voight's been tight lipped. Something tells me it's not going to be above board."

"It's Voight. Of course it won't be." Adam grabbed a bottle of water from the fridge, "This is Diesel. Diesel, That's my buddy Kevin. He's good people, you can trust him." Adam managed to twist the cap off the bottle of water and downed it in a couple of sips.

Diesel was oblivious to the conversation and more focused on the bottle in Adam's hand and kept trying to grab from Adam

Kevin and Adam left the break room and returned to the bullpen just as Harleigh and Kim came upstairs.

"Adam, I got candy. Not you..." Harleigh stopped mid sentence when she saw they weren't alone, she immediately hid behind Kim's leg.

Kim wrapped an arm around her, "Hi everyone. Harleigh, these are my friends. I told you about them. They're going to help us."

"Hey kiddo." Hank kept his distance, "Burgess, there are some coloring books, crayons, and an iPad in my office, along with a playpen for the baby. We need to talk."

Kim wasn't shocked that he had jumped right into it, she knew they had a lot to discuss and more importantly to figure out. They had very little to go on, Harleigh still hadn't given them anything to go on.

They had their work cut out for them.

"Okay, I'll get them settled. Diesel is ready for a bottle and then he'll nap for a bit. Harleigh won't be as easy, she'll be okay as long as she can see me though. She is leery of strangers, men specifically. She's not Adam's biggest fan."

"So she's smart." Halstead quipped.

"You're a funny guy." Adam replied.

Upton approached Adam and Diesel, she placed her hand on the little boy's back, "Hi little man, you sure are cute." She reached her arms out, "May I?"

Adam shrugged, "Sure." He moved to hand Diesel off to her only to have the baby cling to him and begin to cry, "Maybe not.."

Kim was quick to soothe him. "He hasn't done that before." She held him for a few moments before handing him back to Adam, they both followed Hank into his office.

Both Kim and Adam emerged from the office after about twenty minutes.

Hank waited for them to sit at their desks before he spoke, "Here's my plan."

Sorry for the delay in posting this chapter, and I hate to leave you hanging on this one but I've got another story in the works that has jumped front and center and I need to get it out before I can do this one justice.

It's called 'Surprise of a Lifetime', it's basically my take on all the rumors and speculation around episode eight titled 'No Regrets', I hope you'll give it a read.

Thanks for reading!
