(Two weeks later)

It was a few days since jay was released from the hospital when he went back to work on desk duty, He didn't want to be on desk duty but his ribs were still healing. No one from the team knew that Erin had spent over a week at Jay's apartment since he got out of the hospital but they had both clicked and got very close with each other.

Jay sat in his chair while the rest of the team walked into the bullpen and when he saw Erin he let out a little smile which only she saw. His smile broke away when Hank walked out of his office, " Ok i would like to announce that Halstead is of desk duty and out in the field, but we can celebrate later as we have a case to handle!"

"congrats man!" Jay was congratulated then the team quickly moved on to the case

Antonio began to explain the case "alright all we know so far is a 17 years old male was murdered last night and he was connected to a gang on the west side"

" right i want Jay and Erin to go and inform the family and the rest of us will continue to dig through information about who this man was" Hank gave out his orders

" sure thing Hank, at least i have my partner back" Erin began to walk out of the room when Jay stood to his feet and let out a massive groan.

(Erin's POV)

I turn around to see Jay with his hand over his ribs, "Jay, are you ok?", the rest of the team are around me looking concerned

"Yeah i'm fine Er i just stood up to quickly, i'll have my breath back in a minute"

" Jay are you sure your ready to go back out there?" Dawson asked. " yeah i'm fine Tony" jay replied now having his breath back. The two then left the district

(Jay's POV)

I sit in the car acting like i'm alright but i'm still lying about not being in any pain, i nearly got found out back at the district but i can't sit doing nothing for weeks i belong out in the field not sat at a desk. We pull up at the victims parents house and i come back to reality when i hear Erin, " Hello Jay, are you ready to go?"

"What... yeah lets go" we both get out the car and walk towards the house. I knock on the door and i shout "Chicago police department" as we both take a step back.

A young woman came to the door and she let us in, me and Erin both took a seat on the couch and we started to explain until a larger man came through the door, " Whats going on babe?" he said walking up to his wife who was crying

She took his hand and looked up at him, " This is Detective Lindsey and Detective Halstead from the intelligence unit and they came round because they found Nathan's... um.. body last night"

"what no you got it wrong that's not my brother its someone else who died" he was sad but I could see the anger building inside of him.

I got up and started to walk towards him until Erin grabbed my hand, i knew she was still worrying about my injuries so i turned around and gave her a look to tell her it was ok. I carried on walking towards the man and i put my hand on his shoulder,

"Look man i understand how you feel and i'm really sorry but it was him, it was his DNA" i tried to be supportive but he was getting more angry, i went to walk towards his wife when he asked us to leave but when Erin said we had some more questions, he elbowed me in the ribs and i dropped to the floor.

Erin ran over to me and got down on her knees, " Jay can you hear me are you ok. Your gonna be fine!" Next she grabbed her radio, " Officer down, Halstead has collapsed roll me an ambo to 112th Jane street now!"

She sat with my head on her lap until i started to pass out and it all went dark, i was put in to the rig and i was in and out of consciousness all the way but i could still feel Erin holding onto my hand.

(Will's POV)

At Chicago med

I'm walking through the ER when i hear the doors burst open and i hear Maggie, "PD's here take him to Trauma two"

I see Erin and i already know who it is, "Is it jay, did something happen?"

" yeah we were informing a family about a death and he got elbowed and then he just collapsed, he started shouting in pain and then he blacked out. Will he got elbowed in the ribs do you think something has happened?"

" I hope not, but they won't let me in anyway because i'm family so lets go sit in the waiting room. Did you inform Hank and the rest of the team?"

we both take a seat and Erin continues, " yeah they are carrying on with the case but they told me to stay here with jay"

I'm praying my brother will be ok as i only just stopped being angry at the team for before but i knew this wasn't Erin's fault, " He talks about you all the time you know, i think he grows on you the more time he spends with you" Jay will kill me for saying this but i thought she should know.

" really i didn't know that but if you would like to know, jay has grown on me too", " i'm sure he will be fine Will"

The two were left sat waiting not knowing the fate of Jay.

District 21

Antonio puts the phone down and turns to the team, " Guys listen up...that was Erin and she at med with Jay"

" why what happened?" Hank asks

"Jay was talking to Nathans brother and he got angry, he elbowed Jay in the ribs which caused him to drop and black out"

"Ok call Erin back and tell her to stay with Jay at all times" Hank said as he walked into his office hitting the door on the way.

Back at med

" hey Jay, how are you doing over there man, i can see you?" he heard his best friend Mouse trying to joke with him over the radio

" I'm fine bud what do you want?" i looked over to his rooftop and i'm pretty sure i can see a smile. I look back in front of me when a see an unmarked vehicle driving towards us, i grab my radio while looking through my sniper, " Hey mouse, have you seen this car, do you know who it is?"

"No i don't what do you wanna do?" i was about to tell Mouse when the building next to me was blown to pieces. I grab my sniper and side arm and crawl across the floor to get out of my building. i reach the bottom and find mouse, " Hey man are you ok?"

" yeah i'm fine lets move" he shouts over the sound of gunfire. We both walk out of the back of the building when an RPG hits the same building and it collapses down on top of me and mouse

I wake up with my legs trapped under rocks and i see mouse crawling towards me, " Hey Mouse are you good to help me?" i shout

" yeah i'm coming" he gets to me and my eyes begin to flutter, I feel mouse tapping my face, " hey Jay can you hear me bud?"

"yeah i'm here" i open my eyes as i see mouse's eyes shutting and then he falls beside me. " MOUSE GET UP COME ON, MOUSE... MOUSE" I shout mouse one more time when my eyes shoot open and i'm breathing heavily.

(Erin's POV)

I'm asleep next to Jay when i hear him muttering i sit up and see him frantically moving about in his bed, " Will!" i shout out of the room. He comes running in and stands next to his bed " Will whats going on?"

"Wait be quiet, I've seen this before. When... when he came back from Afghanistan, OH NO, he's having a PTSD episode it must have been triggered from the explosion"

"Well lets wake him up then" i say as will grabs my arm

" No you should never wake someone up who is in this state, it can make them violent trust me i have seen it before.

I sit back down i my chair watching him toss and turn when he begins to shout something about a Mouse or something, " Will why is he shouting about a mouse?"

"Not a mouse, Mouse his best friend, who he served with in the rangers, he hasn't spoken about him for months"

Next thing i know i look back at jay and he shoots out of bed. Will runs to him and holds him down, " Jay its your brother Will, your in Chicago in the hospital, i'm here with your partner Erin." The more Will spoke to Jay he began to calm down and lay back down. I went and sat beside him and took his hand, i moved closer toward him and said, "You're ok now, your safe i'm here" i felt the grip tighten on his hand and he took some deep breaths to calm down.

A few hours later

I arrived back at the district and buzzed myself up to intelligence, "Hey hows he doing?" Adam asked

"He's alright and feeling a bit better, he's been sent home to rest so i'm gonna go and see him later" I left out the part about his PTSD episode.

"Go see him now, we've just about finished the case anyway"

"Thanks Hank" i say as i walk done the stairs.

At Jay's apartment

I walk up to door and knock on it a few times to hear Jay, "It's open"

I push the door open and see him laying on the couch, "Hey i just thought i would come and check on you to see if you are feeling any better?"

Jay gave me a little smile and i sat next to him, " Yeah i'm feeling much better the doc just said i need to let my ribs heal properly.

"or you know, you could just learn to avoid flying elbows!" i say laughing as jay pushed my arm, "haha very funny Erin" he says sarcastically.

(Nobody's POV)

Erin and Jay are sat watching TV when Erin decides to more a little bit close but Jay notices

"Hey you ok?" jay asks

"Yeah i'm fine, wait no i'm not i can't pretend anymore" Erin looks up a Jay and she grabs the side of his face and kisses him, she can tell he is shocked but he doesn't pull away and this kiss last for at least 20 seconds.

Jay pulls away and looks at Erin, " I didn't know you felt the same way" he lets out a little laugh

"Well it was about time Halstead!" Erin says

Jay stands up and takes Erin hand, " come on lets go" he says while he picks Erin up even though it hurt his ribs but he ignored it. "Where are we going?" Erin asks

"To the bedroom!" he says while laughing

I hope you enjoyed this part. i finally found the right place to start off Linstead and there is plenty more to
