A\N: So I didn't get a chance to post my versions of all the episodes so I could be caught up by this week; however I do think that I'll be all up to date when Chicago PD comes back in January. A huge thank you to all of my friends on Twitter who helped me come up with ideas for this one.

Spoilers: Based on episode 2.04 "Chicken, Dynamite, Chainsaw"

Chapter 4

"Hey Dawson," Sergeant Platt quipped as he walked into District twenty-one, "You have a mini-me?"

"You're Sergeant Platt," Diego walked towards the desk and looked up at her, "I remember you from before."

"Hi," Platt responded to the boy.

"Alright Diego," Antonio had one foot by the stairs and the other one on the first step, "Lets go alright."

"Okay Dad," Diego turned and walked back to him, "It's so cool you need a passwords to get it," He marveled at the hand print and key code system, "Can I put that in my essay?"

"Sure."

"I'm going to have the coolest essay ever!" He cheered happily, "So can I come with you when you catch people?" He wondered.

"No, you stay here alright, that reminds me though," He led him over to Nadia's desk, "This is Ms. Nadia she works here and helps out. When all of the detectives are out she's going to be watching you alright?"

Diego was about to complain about not going in the squad car when Nadia smiled at him and he suddenly began to feel okay. "Hi Ms. Nadia," He finally got back his words, "I'm Diego."

"Hi Diego, so I hear you have to do a report for school."

He just stared at her, unable to come up with anything to say, "Uh-huh."

"Well if you need any help just let me know."

"Uh-huh."

Diego wasn't sure what was going on. He wasn't usually shy and he hardly ever was at a loss for words, he just couldn't speak to Nadia. Thankfully though Halstead and Rusek came up to him and distracted him.

"Hey little man," Halstead fist bumped him.

"Hi Detective Halstead, hi Officer Ruzek."

"So polite," Ruzek looked down at the young boy.

"Yeah you could learn from him," Alvin Olinsky quipped.

"Ha, very funny Al."

"Alright Diego, you sit here and start working," Antonio led him to his desk where he had set up an extra chair, "Take some notes and then I can show you around."

"I see you've all met our special visitor," Hank Voight walked out of his office.

"Sergeant Voight Sir!" Diego stood and rushed towards him, "Can I ask you a question?"

Voight looked down at the kid, "Yeah sure."

"How do you spell your name?"

"Here," He reached into his pocket and handed him a card. An act he didn't think meant anything.

"Cool!" Diego's eyes lit up, "I'm going to show my class!"

"Okay," Voight rubbed his hands, "Now we don't have any new cases yet but you can all catch up on some paperwork."

"Daddy I wrote down some names," Diego showed his father his binder, "Can I see the interrogation room now?" He asked hopefully.

"Yeah sure," Antonio stood up but just then Voight came into he room, "We have a new case, Antonio you uh might want…" He nodded towards Diego.

"Yeah, come on Diego lets come downstairs and see Sergeant Platt."

"Why?" He wondered.

"Because there are sometimes you're to young to see."

"Like dead bodies," He concluded and followed his father back down the stairs.

"Platt we got a new case and its kind of sensitive. Can you watch Diego for a bit?"

"What I'm I a baby-sitter?" She quipped but Antonio was already halfway up the stairs, "Alright kiddo lets see what you can do." She waved him behind the desk, "What's your name again?"

"My names Diego, Ms."

"Ms.? Don't think I've heard that in awhile."

'That's what I call my teacher."

"Ah well you can call me Sergeant Platt."

Diego took the cap off his pen and wrote it down, "What do you do?"

"What do I do? I keep the whole place running."

"You give people jobs right?"

"Yeah sometimes, I do other things too…"

"Hi Ms. Kim!" Diego interrupted her and smiled as he saw Officer Burgess walking by.

Burgess turned on her heel, "Hi, Diego right?"

"Uh-huh. It's a PD day and I'm doing an essay. Can I as you a few questions?"

"Wherever he got his manners from it wasn't his father," Platt quipped.

Ignoring her comment Burgess turned to the boy and said, "This is Officer Roman. He's my new partner."

"Hi I'm Diego Dawson."

"Antonio's son," He concluded.

"Uh-huh. I'm going to be a cop just like my Dad."

"Well you seem to have everything figured out."

"I do. Do you do the same things as Ms. Kim Sir?"

"Bud you don't have to call me sir."

"Mommy and Daddy say to treat adults with respect."

"That's right," Antonio responded as he walked back down the stairs, one foot holding the gate open, "Come on Diego Detective Halstead and Officer Rusek are going to get you set up in an Interrogation room."

"Cool!" He rushed off and followed his father.

"Wanna learn how we interrogate suspects?" Halstead asked Diego as they got back to the unit.

"Dad can you show me?" He asked.

"Later bud but I have some work to do."

"Yeah come on, I'll show you," Halstead promoted him and Diego smiled and went along with him.

"Can I integrate you?"

"Oh this'll be fun," Ruzek leaned against the interrogation room door and smirked.

"How about we interrogate Rusek first?"

"Okay," Diego agreed, "Sit in the chair," He told Ruzek.

Sending a glare towards Halstead Rusek did as Diego told him to. "Okay," Diego began, "Where were you last night?"

"Last night?" He repeated, "What do you mean?"

"That's when the murder took place. It was last night!"

"He's good," Halstead commented.

"Hey you too, time to do some real police work," Lindsay poked her head around the door, "Hey Diego," He smiled at the boy.

"Hi Detective Lindsay."

"What about Diego?" Ruzek wondered.

"Antonio said Nadia can watch him. You Dad wants you to do some work alright."

"But I like his work," He pouted.

"We can finish Rusek's interrogation later buddy," Halstead promised and ruffled the young boys hair as he walked out the door with Lindsay.

"Can you stay?" He turned to Ruzek and asked hopefully.

"Not sure," Ruzek shrugged and began walking back into the bullpen Diego following.

"Why aren't you a Detective?" He wondered.

"Because he's just a baby," Olinsky quipped, "He needs more experience."

"Oh he's learning. Are you his teacher? Daddy says you pulled him away from the school. Can you do that to me?"

Olinksy laughed, "Sorry kid, maybe in a few years. I think you're still a little young for this type of work. Good to know you're interested though."

"Yeah," He smiled, "Detective Halstead showed me how to interrogate and I asked Officer Ruzek questions."

"Oh did you know? Well I'll have to see that later. Why don't you come up with some questions you could ask him?"

"Alright," Diego ran off to his father's desk.

"Thanks Al," Ruzek stared at the older man.

For lunchtime Antonio took Diego to Laura's bakery and Diego skipped in and went up to the counter, "Hi Eva!" He smiled at his older sister.

She playfully frowned, "They didn't lock you up yet?"

"Hey," Antonio warned, "That's not nice. The only people I lock up are bad guys and any boy that hurts you."

"Dad!" She let out a dramatic sigh.

"Okay all three of you," Laura put up the 'closes for lunch' sign in the window of the door, "Lets have a nice lunch in peace alright."

"Fine," Diego and Eva said in response and quiet for the most part they are their sandwiches.

"So Diego what have you done so far with Daddy at work?"

"I met lots of nice people," He smiled, "Ms. Nadia is really nice and Sergeant Voight gave me a card."

"Nadia? That the one…" Laura trailed off and say Antonio nod his head,

"What? What?" Eva wondered.

"She's one of Detective Lindsay's friends," Antonio told his daughter. "She answers phones and take notes."

"I like her," Diego smiled widely.

"Ooh Diego has his first crush." Eva sighed, "That's so cute," She made fake kissing noises.

"I do not!" He yelled.

"That so means you do!"

"Okay, okay," Antonio waved his arms, "Enough."

The family finished up lunch and Antonio and Diego headed back to the district. Antonio took him up to the bullpen and left him with Halstead well he and Lindsay went off to the hospital to interview a victim.

"Hey bud," Halstead pulled something out of his desk drawer, "I got some candy and Oreo's, wanna learn how to play poker?"

"Cool!" He cheered happily.

"I want in," Ruzek spoke, "Although his Dad is gonna freak," He pointed to Diego.

"Only for Mommy's sake," Diego spoke and it caused both older men to laugh, "What's so funny?"

"Nothing little man," Halstead ruffled his hair and led him into the interrogation room.

Halstead and Ruzek taught him the basic knowledge of poker and then began playing dividing up the candy among them and using the Oreo's as scoring pieces. Diego was doing pretty well and he had just won another hand when the door to the interrogation room opened.

"You're teaching him how to play poker?" Kim Burgess exclaimed, "You know you're lucky I came in here, his father's coming back here to integrate a suspect."

"Oh cool," Diego cheered, "I want to watch him," He stood and hurried off but Burgess stopped him.

"Are you allowed to watch?"

"Uh-huh I see it on TV all the time."

"We'll wait until your father gets here," She told him, "Go back into the bullpen."

"Okay," He went to collect his candy first and then walked out of the interrogation room.

"Really? You're teaching a minor how to gamble in a police station?" She shook her head at the two men and she went over to the table and snagged most of Ruzek's candy stash, "You two better hide the evidence before Detective Dawson comes back.

"Right," Both men began cleaning Ruzek sending Burgess a wink and a flirtatious before she left the room.

"Diego?" Antonio walked towards his desk, "Who gave you all this candy?" He questioned.

"I earned it playing poker," He explained.

"Poker?" Erin raised her eyebrows, "Let me guess…" She turned to see Halstead and Ruzek walking back into the room. "These two taught you?"

"It was fun," Diego grinned.

"Hey man you spilled on us?" Halstead pouted.

"If I didn't my Dad would be even more mad," He shrugged and went back to eating

"For the record I would like to point out that it was all Halstead's idea," Ruzek accused and then swiftly walked away.

"Thanks man," Halstead rolled his eyes, "Look man," He tuned to Antonio, "It was just for candy and the kid had fun. No real gambling involved.

"I still can think of a punishment," Antonio smirked, "Later." He ruffled Diego's hair and headed towards the interrogation room.

Later after the case has been solved Diego sat facing Halstead and Ruzek in the integration room, a grin spreading on his face, "You are accused of teaching a minor to gamble," He walked around them, "You were caught candy handed. I have a witness who'll collaborate my story."

"Collaborate," Ruzek mouthed. H didn't think that was a word any eight year old knew let alone could use in a sentence.

"No talking!" Diego turned on his heel and stared at him, "You're going to jail. I think one hundred years will be enough time. Now let mw take your fingerprints and all your candy."

From behind the one-way mirror Voight turned to Antonio and said, "He's pretty good for a kid. Maybe one day this city will have another Detective Dawson."
