AN: Hello everyone! How are you doing? I hope everyone is ok!

I thought it was time for some good Will and Jay Halstead whump! I have nott seen this season as I plan on doing it during the summer, so please do not spoil me anything.

This story was inspired by the prompt: Character A tilting Charachter B's chin up to get a better look at their face and the evidence of fight. A delicately thumbs away the streak of blood by B's mouth, saying nothing as they examine it. After a brief pause, B's heart skips a nervous beat as A looks them dead in the eyes. Their voice is quiet and tense, their anger barely restrained. "Who did this to you?"

Will Halstead was screwed. OK, maybe he was exaggerating but, knowing the conditions he was in he was certain that his brother would think he got in other bar fight as he so used to so often do before he got back on the right road. He was supposed to help the Intelligence Unit on some case when, while walking towards the station, he was stopped by some big men. At first he had no idea who they were, but then he recognised a man whose wife was a patient of his. Unfortunately, she was already dead on arrival so there was nothing to do. The young man blamed his wife's death on Will and the redhead had added her name to the notebook he kept with all the names of those he had failed to save. It seems that the man- who was named Gregory Kasten- had found some friends and had followed him. When they attacked him, he hadn't had the possibility to avoid the fight or defend himself and he could only try to protect his head with his arms as punches and kicks rained down on him. Will was certain that the kick he had received to his chest had some cracked ribs as it hurt to breathe and he could already feel the bruises forming. He was sure that he had at least a black eye and a cut on the very top of his forhead. he knew he was bleeding from the cut and it looked worse than it actually was. Now here stands problem number 2.: he had two choices which were either walk into the station bleeding and telling everyone what had happened or going home to clean up and telling Jay he had gotten in a bar fight (which he didn't want to do, he hated the disappointed look on his brother's face) and tell him he couldn't come to help with the case. Will sighed as he got up from the ground groaning, his head spinning. Maybe his head injury was worse than he thought. The doctor realised in his not-so-lucid state that he really didn't have the energy to go home and he didn't want Jay to look at him like he used to when he was disappointed in him so he took the worst decision he could possibly take and dragged himself to the station. As he entered the door he saw Platt yelling at some poor officer and approached her.

"Hello seargent, can you buzz me up please? My brother needed some help on a case."

"Ah I see, the other Hal- what the hell happened to your face?!" the sergeantooked at him like he was about to die or something and Will looked at her confused. Then he remembered about the cut on his head and touched it, slightly flinching at the sharp pain on his head.

"Oh yeah, some angry family member of a patient who unfortunately didn't make it. Nothing to worry about".

She looked at him suspiciously but then she grinned and Will immediately knew he was in big trouble. Oh no.

"Would you like to prank your brother?"

"...Is no an acceptable answer?"

"Do I look like I could take no for an answer?"

"OK, please don't kill me, what do I do?"

Platt's smirk grew. Honestly it was kinda scary. "Just act like you feel worse than you are."

"I think I might have cracked ribs".

"Good. Act like they're broken". He sighed. "Ok".

Platt smiled. "Good boy". she pick up a phone and- damn, his vision was getting in out of focus. He really needed to sit down. Platt's voice brought him back to reality.

"Chuckles? Yes, yes, come get your brother, he is bleeding on my floor and looks like he's about to drop dead. Ok". She put the phone down." All is done"

Not five seconds later they saw Jay run downstairs at a speed that made Flash pale and was literally jumping on Will who, feeling suddenly embarrassed put his chin down to avoid his brother's eyes but Jay was having none of it. Jay tilted Will's chin up to get a better look at his face and the evidence of fight. The detective delicately thumbs away the streak of blood by B's mouth, saying nothing as he examined his. After a brief pause, Will's heart skips a nervous beat as Jay looked him dead in the eyes, his voice was quiet and tense, his anger barely restrained. "Who did this to you?"

Will flinched, and took a step back as he tried to avoid telling Jay the reason of his injuries but as he did he felt a sharp pain by his ribs and he cried out, putting a hand on his chest. Jay put his anger aside, deciding that caring for his brother was top priority. He put an arm around Will's shoulders and took him upstairs, gently making sure that he didn't fall. When Will finished climbing the stairs, his ribs hurt like there was no tomorrow and he felt lightheaded. Jay noticed his brother couldn't stay upright for long so he took him to sit on one of the chairs and Will couldn't have been more grateful for his brother's understanding than he was at that moment. Jay saw Antonio bolt from his seat and Kim and Kevin, who were talking, rush over. Will suddenly noticed the rest of the team and tried to regain at least some control of his breathing. Hailey, the saint, appeared with a first aid kit and a mirror and Voight came out from his office to see what the commotion was about. Everyone started asking questions on the same time.

"Are you OK Will? What happened?" Hailey asked her voice as sweet as she was. Will really couldn't see why his brother was so stupid not to see that she was the one, but right now it was not the time to think about it.

"Who did this to you?" Antonio growled protectively. Will had no idea how he had grown so protective of him, probably because he was Jay's little brother.

"Can you tell me where it hurts? I will go take some ice!" said Kim as she walked away to take some ice.

"Woah man, there's a big cut you got there! Do you have a concussion?" Kevin said as he looked worriedly at the redhead.

"What's going on?" asked Adam as he walked in the office, seeing Will for the first time.

"What happened." Voight's demand cut through all other voices as he looked at Will and everyone shut up. The doctor knew he couldn't escape from this and took a deep breath and started explaining.

"I had a patient, Katrina Kasten, she was assigned to me but unfortunately she was DOA. I declared her death but her husband, Gregory Kasten, did not take well the news and blamed me. Long story short, he and a few of his friends decided to teach me a lesson or something."

Voight noded taking in the information as Jay and Antonio looked murderous. Kim came back with the ice and Will thanked her, placing it on his damaged ribs. Silence.

"You didn't say anything about ribs" Jay noted, worried.

"Well, I have bruises everywhere but my ribs are probably cracked, so they hurt quite a lot" Will responded while using the mirror and the first aid kit Hailey provided to clean his cut on his head and put on a Band-Aid. He also cleaned away the thick amount of blood straining his features and get a clearer look on his black eye. He poked at the bruise, flinching and deciding that he couldn't do anything about that. He sighed and tried to find a position where breathing didn't hurt and pressed the ice on his injured ribs tighter.

"We will find this asshole" Jay said looking ready to kill.

"No. He lost his wife and is already grieving. Don't do a thing, I will not press charges" Will responded.

Jay immediately started bickering with his brother in order to convince him but Will was irremovable on his position so he decided to back down. For now.

The redhead insisting on helping the team with their case and did everything he could to give them as much precise information as he could in order to help them gather evidence. Once he finished helping the team, Voight ordered Jay to drive his brother home. The older Halstead nodded and picked Will up, getting him in the car. As he saw the doctor fall asleep he smiled and drove them silently home. He helped Will out of the car and into their shared apartment. Will protested as Jay tried to get him out of his blooded scrubs, frowning in pain. Jay's anger returned once he was able to see the full damage and the horrible bruises on his brother's chest and back. It was hard to find some skin that was not heavily bruised. Jay swallowed his anger and put his brother to bed, promising on being home early so he could look after him. He then left the apartment and returned to the station, where Voight looked at him in that way that told him that they were not letting this go.

"Alright. Now it's time to find Gregory Kasten"

AN:
