A/N: Hello guys! This is my first Chicago PD fanfic and to be honest my first fanfic in English. English is not my mother tongue and I know that I messed up some things in this story. Sorry for that. If you want me to continue this, please leave a review and if somebody wants to become my beta reader I would like to meet you. Anyway I realize that I´m talking too much. Enjoy!

PS: I don´t know if I need to do that but there will be a mention of child abuse. I know that the things I wrote down are possible not true but I hope you don´t mind.

Intelligence had just finished a very rough case and was now sitting at their desk doing paperwork. Nearly everybody seems mentally and physical exhausted and was relieved that the case was finally solved. Except for Voight. But he looks grumpy everyday so nobody worries about that.

Although they were glad that Richard Keller won´t see the sun for the rest of his life nobody wanted to start their paperwork. Antonio was staring at a picture of Jules Willhite and was deep in his thoughts. Erin was playing with her grenade and seems to be lost in her thoughts too. Ruzek and Atwater were just staring holes in the ceiling and Olinsky just sat there and watched Jay Halstead. He seems to be affected the most after this case of Richard Keller.

He was in prison because of murder and rape of four seven to nine-year-old boys which sounds pretty much like Lonnie and Ben Corson. So Olinsky just sat there and watched an utterly exhausted Halstead who seems to be more sleeping than being awake. He also noticed how Jay slowly relaxed as he realized that it is over now. Everybody was ripped out of their thoughts as Sargent Trudy Platt slowly made her way up the stairs to the unit.

"Halstead! There is somebody downstairs who is waiting for you. Continuously yelling for his son Jason." Then she turned around and disappeared. Alvin saw how the tension came back into Jay as he clenched his teeth and fists. Jay tried to ignore the questioning looks of his teammates and slowly made his way downstairs. Stopping at the last pair of stairs he tried to calm down as he watched his father, standing there in the district with a bottle of beer in his hand, trying to keep his balance as he saw his son.

"JASON, MY DEAR!"

he shouted through the lobby thing. It seems impossible but Jay tensed even more after these words. Still trying his best to ignore the glances of Platt and other patrolmen he grabbed his father's arm and pulled him out of the district. "What the hell was that? Why are you even here?" Jay shot angry looks at his father Frank as he took another sip of his Guinness. "Stop staring at me like that. I´m your father. I am supposed to visit my son at work." Jay could not believe what he just heard. "So you are just here because you are supposed to do that?!" He nearly split out. "If that is the only reason you have done your job. You are free to leave." The younger Halstead turned his back to his father and tried to go back to work as Frank grabbed his wrist and spinned him around.

Jay did not want his father to see how much pain he caused his son so he pulled his mask in pace and shot angry glances at him. "You are not talking to me like that, son!" Frank said trough gritted teeth. He was pissed at his son for turning his back at him so he punched Jay straight in his ribs. Now Jay had a hard job to oppress the waves of pain that shot through his torso. His father still knows how to punch after all these years. Frank smiled and released his grip at Jays wrist. He saw the slight bruising he had caused with his hand and smiled even wider. Jay was always somebody who was bruising very bad and very fast which caused several problems in the past. But Jay still pulled his sleeve over his wrist and tried to act as normal as he could. Without another word he turned around and went back into the district as his father slowly made his way to his car.

As Halstead entered the building he was relieved that most of the patrolmen and women are gone. Although Sargent Platt was still looking at him with that strange look Jay felt much better at the district than outside with his father. He just nodded and headed to the stars which lead to his unit. Of course everybody looks at him as he returned but he tried to act normal so he just said that he doesn't want to talk about it. Hissing slightly in pain as he sat down Jay tried to concentrate on his paperwork he felt a hand on his shoulder which caused several more pain as he nearly jumped up from his seat. But it was just Alvin. "You´re alright kid?" He asked with a worried glance. Jay simply nodded and was not surprised as Alvin quietly sighs. Even if Jay tried his best to hide his emotions Alvin could always read him like an open book. So of course he knew that Halstead wasn't alright. Alvin took his hand from Jays shoulder and whispered: "You know I´m always there if you want to talk." "Thanks" Jay muttered under his breathe before both returned back to work. It took some time but after a few minutes Jay allowed himself to fully relax and forget about his damn dad for a while, not knowing that it wasn't over.

Another hour or so took by before Voight told all of them to go home and sleep. Unfortunately, Ruzek came up with the idea of going to Molly´s and although everybody was really tired they decided to join him.

Olinsky and Voight stayed for a couple minutes, just sitting in silence in the now empty work area. Suddenly Voight began to speak. "You look worried Alvin." Olinsky sighed. "I guess I am" he said after a few seconds of silence. Voight just looked at his friend, encouraging to go on. "I watched Jay the last days a lot and I don't think he is okay." Al finally admitted. That doesn't surprised Voight. He knew Alvin and after some years he also knew Halstead. He just never thought that he and O would have to speak about Jays health. Apparently he didn't know what to say so he remained quiet until Alvin continuous to speak again. "First of all there was this whole Keller thing which reminded me pretty much about Lonnie and I´m sure as hell Jay feels the same." Al paused and gave Voight time to understand. As Voight nodded he got on. "My second worry is about Halstead´s father. I watched him as Trudy told him that his dad is downstairs and suddenly he was so tensed up again. Did you ever thought of the fact that his relationship to his father is a lot different than we think it is?"

This time Voight shook his head. He admitted that he had never thought of that. Jay was always very good at hiding emotions and feelings and to be honest Voight had never asked him about his dad. "How bad do you think it is?" Voight asked after a few minutes. Alvin sighed again. "I really don't know. Maybe I´m just… I don't know for sure but I think we should keep an eye on him." "Yeah, that is probably a good idea, Thanks for talking to me." Olinsky simply nodded before he grabbed his coat and made his way home. Voight stood there for a moment, regretting that he knows in fact nothing about Detective Jay Halstead.
