I hope you enjoy this!

It was just after 11 on a Saturday night, Jay and Hailey had called it an early night after what had been an easy but tiring first week back at work together.

Jay was woken up by his phone buzzing away on his bedside table, he thought about ignoring it but as he saw Natalie's name flash up on his screen Jay knew this must be something important.

"Hey Nat, what's up?" Jay spoke sounding half asleep.

"Jay you need to get here now, oh my god." Natalie cried out down the phone.

"Nat where are you? What's going on?" Jay was definitely fully awake now.

"It's Will, he's been assaulted. I'm at his apartment, just get here Jay."

"I'm on my way Natalie, make sure you're safe." Jay put down the phone and searched for some clothes to wear. As he was putting his shoes on Hailey woke up and wrapped her arms around Jay's waist.

"Sorry I didn't mean to wake you, go back to sleep babe." Jay spoke softly as he felt Hailey's arms wrap around him.

"Where are you going?" Hailey questioned.

"Something's happened at Will's, I'm not sure what has happened at the moment but I need to go."

"Do you want me to come with you?"

"No you go back to sleep babe, I'll call you when I know more." Jay replied, giving Hailey a quick kiss before leaving.

Jay drove as quickly as he could to will's. As he pulled up to Will's apartment complex there was a couple of patrol cars and an ambulance in the street. As Jay approached the front entrance he was met by the sight of Will being wheeled out on a stretcher. His head was wrapped in a big bandage, his shirt as stained red from his own blood and an oxygen mask covered his face.

"Natalie! How's he doing?" Jay questioned as Natalie came into view.

"I'm not sure Jay, he's got a pretty nasty head injury and some broken ribs but we won't know anything for definite until we get to the hospital." Natalie was trying to keep calm but Jay could tell how worried she really was.

"Alright, I'll get someone to escort you to the hospital and I'll be there after I've secured the scene."

Jay ordered a patrol officer to escort Will to the hospital and Jay headed up to Will's apartment. The front door of the apartment had been kicked in, the living room looked like a war zone. The grey couch was covered in blood, glass from the now shattered coffee table was spread across the room and the lamps were broken. Jay checked around the apartment for anything that could have been robbed, Will's phone and Laptop were left in the living room and most importantly, Jay's mom's engagement ring was still there. It soon occurred to Jay that this was a targeted attack on his brother and not a robbery gone wrong.

"Roll the crime lab down here and sweep this whole place for fingerprints. No one is allowed in there useless they have a good reason to be in there." Jay demanded to the young officer who was on guard at the front of Will's apartment. The young officer following Jay's demands.

Jay called the one person that he knew would go to any length to find the person that did this to his brother. "Voight meet me at Chicago Med, we've got a new case, this one is personal."

Voight strolled into the waiting room at Chicago med, he spotted Jay leaning against a wall in the back corner. "Halstead what's going on?" Voight questioned as he approached Jay.

"It's Will, someone kicked down his door and assaulted him. It didn't seem to be a robbery gone wrong as nothing of value was missing."

"How bad are his injuries?"

"I'm not too sure I haven't received an update since I got here. Natalie said he had a nasty head injury and broken ribs but that was when I first arrived at his apartment."

"Alright then, I'll stay here with you and I'll call everyone in first thing in the morning. Don't worry Jay, we're going to find this prick and make him pay."

"Thanks Voight, it really means a lot."

"Like I said the other day Jay, were all family up here so if someone attacks you're family it's like they're attacking our family."

It was around 45 minutes later when Natalie approached Jay and Voight in the waiting room. Jay was the first to spot Natalie, she didn't look overly worried but she was definitely worried. "How's he doing Nat?" Jay questioned eagerly.

"He's not doing too bad, We're a bit concerned with his head injury buts there's no damage to his brain, he has a couple of broken ribs but that's the worst of the injuries." Natalie informed the two men.

"Has he said anything about what happened or who attacked him?" Voight joined into the conversation.

"No he hasn't, he was unconscious when I arrived and he's got a pretty bad concussion so he's resting at the moment." Natalie tried to keep herself together but as a couple of tears trickled down her cheeks she broke down, Jay quickly wrapping his arms around her before she fell.

"Hey Nat don't worry, Will's going to be fine and we're going to find the bastard that did this." Jay tried to comfort Natalie as she continued crying in his arms. Voight leaving the two for a minute.

"Why the hell would someone do this to Will, what's he done to deserve this. He's a good man, he cares so much for people yet someone can do this to him." Natalie was pouring out all of her emotions to Jay, something which Hailey was doing in the exact same hospital a couple of months before.

"Life isn't fair Nat, innocent people get hurt for no reason, and I see that all too often. You just need to stay strong, Will hasn't been badly injured and whoever did this is going to pay." Jay reassured Natalie who was now calming down.

"I'm sorry Jay, you don't need me being a soppy mess when you've already got enough to deal with." Natalie apologised.

"Don't worry about it Nat, I know how much my brother means to you so it's only natural to feel this way." Jay smiled reassuringly back towards Natalie who had a little smile on her face now.

Everyone arrived at the district in the morning, they were all confused to why they were called in on a Sunday morning. Jay and Voight weren't there when everyone arrived, Hailey hadn't heard anything from Jay all night so she was a little worried about what had happened to Will.

Jay and Voight arrived together, as they walked upstairs they were welcomed by confused looks from the rest of the unit. Hailey flashed a small smile towards Jay but she was meant by a blunt look from Jay. There was a look in his eyes that Hailey had never seen before, he was angry and Hailey had seen that on previous occasions. But this time he was more than angry, he was absolutely raging inside, he was a ticking time bomb that was ready to blow.

"Right I'm sure you are all confused to why you've been called in and Jay will fill you in on that. But before we start, welcome back Mouse, it's great to have you back, all of us missed having you up here." Voight announced. "Over to you Jay."

"Last night someone broke into my brother's apartment and assaulted him, thankfully his injuries aren't too serious so he should make a full recover. This seemed to be a targeted attack and not a robbery gone wrong, all of the valuables in Will's apartment were untouched. The time scale for this attack is between 9 and 11, Will got off work at 9 and Natalie arrived just before 11 and found him unconscious on the floor." Jay explained.

"Before we go any further, someone attacked our family. We're going to keep this in house and we will go to any length to find this person. I don't care whether they come back in cuffs or in a body bag but we're going to make sure this person pays for what they have done. So if anyone doesn't want to be involved now is the time to back out." Voight spoke, no one stepping forward to back out.

"What's the plan then boss?" Ruzek questioned.

"We don't know who the attacker is yet, so the first thing is to identify them. Mouse, Atwater and Rojas look through cameras around Will's apartment, see if there's anything on them. Burgess and Ruzek head to the apartment block and she if anyone saw anything." Voight barked out his orders.

Jay had retreated to the break room as the others got the wheels in motion, Hailey left him for a few minutes before going in. Jay was looking out of the window when Hailey walked in. "Hey how are you doing?" Hailey pushed carefully.

"I'm fine." Jay snapped back, immediately regretting his tone of voice, he turned around to look at her, the angry look on his face was now gone, it was replaced by a dejected look. "I'm sorry I didn't mean to snap." Jay replied sheepishly.

"Talk me, what's going on in that complicated head of yours." Hailey smiled back as she wrapped her arms around him, resting her head on his chest.

"Everything in my life was starting to go well for once. What we've got going on has been absolutely perfect, I'm finally fully recovered and back at work, Mouse is back in my life. But now this has happened, I can't catch a break at the moment. If it wasn't for you I don't know where I'd be." Jay spoke as he held onto Hailey closely, a couple of tears forming on his face. Hailey just stayed there silently, letting Jay pour out all of his emotions.

"This was the room where I realised that I loved you." Hailey declared out of the blue. Jay looking down at her with a confused look on his face, waiting for her to explain.

"When you were kidnapped I was in here breaking mugs as I was so upset that you were missing. I knew I loved you but I wasn't sure what that actually meant, whether it was as a partner or something more. However in that moment it made me realise that it was something more, it made me realise that I was lying to myself, that I needed and wanted to be with you." Hailey confessed.

Jay couldn't find the words to respond to her, so instead he lowered his head to hers and they locked into a passionate kiss, pulling apart a few moments later. "I love you so much Hailey." Jay spoke as he locked eyes with Hailey.

"I love you too Jay." Hailey smiled back.

"Sorry to disturb you lovebirds but I've found something you might want to look at." Mouse interrupted, Jay and Hailey eagerly following him.

"Right so there isn't any cameras on Will's floor but I did catch this on one of the outside cameras." Mouse spoke as he turned his monitor towards Jay and Hailey. The screen showed a male figure wearing all black clothing and something that was covering his face. "So that's the sighting of him we get exiting Will's building at just after 10, I managed to track him using other cameras to a car parked a couple of streets down." Mouse continued.

"Who's the car registered to?" Jay questioned.

"The car was reported stolen 3 weeks ago from a car park on the south side, there's no cameras there so I have no idea who stole it. But when I was looking through traffic cams before the attack I noticed the same car following Will and we get a partial look at his face, but it's not enough for facial rec." Mouse explained.

"You could've started with that Mouse, but good work anyway. Right so we have to believe that this person has been following Will from work, so it seems that this revenge against Will for something. I'll go and see Will and Nat to see if they can ID this person." Jay and Hailey quickly left the district heading for Chicago Med.

"Hey Natalie, how's he getting on?" Jay greeted Natalie as he and Hailey entered Will's hospital room.

"He's doing alright, struggling a bit with the concussion but overall he's doing pretty well. How's the investigation going?" Natalie questioned.

"That's what were here about actually, we've got a photo of the attacker that we what you to look at." Jay showed the photo that Mouse had found to Natalie and her facial expression instantly changed.

"You've got to be kidding me."

"Do you know who it is?" Jay questioned sounding confused.

"Yeah it's Phillip Davis, He's the person I was seeing for a while. After my TBI from the crash he took advantage of my memory loss by putting an engagement ring on my hand and made me believe that we were engaged. As I started to get my memory back I realised that something wasn't right and called things off. While I was doing that Will came out and exposed what he had done as Dr Marcel spotted what Phillip had done and told Will." Natalie explained.

"Do you have an idea where he might be?" Hailey questioned.

"No, he ran away after what happened. He even left his daughter, his sister ended up taking care of her and brought her into hospital."

"Ok, that's something we can work with, I'll get Ruz and Burgess to go talk to the sister." Hailey responded as she quickly got on the phone.

"Right so let's go through everything we've got." Hank spoke out.

"The suspect is Phillip Davis, Natalie's ex. The two of them got close after Phillip's wife died from an aneurysm during the birth of their child. Phillip took advantage of Natalie's TBI by making her believe they were engaged. As Nat got her memory back she called things off with Phillip and Will was also there when this happened. So this seems to be a revenge plan on the two of them." Jay explained.

Mouse was the next one to add what he had found out. "I've looked at the cameras in the parking lot at Med and the same car that was used after the assault was spotted there on 4 previous occasions. On each occasion it followed either Will or Natalie out. I haven't managed to access GPS data yet but I'm working on it. The car heads south from Will's apartment for as far as I can track it but I haven't been able to pin point a location yet."

"So I and Burgess let to question the sister. She and her husband had cut all communication with Phillip but she did say her husband saw him outside their house 10 days ago in the same car." Ruzek explained.

"That's all good stuff. So we know he must be staying somewhere in Chicago, obviously not at his own house so let's look into friends or anything that might help us find out where he's staying. Mouse I'll get a warrant so you can access the GPS data." Hank replied.

The next few hours the whole team spent trying to narrow down locations to where Phillip could be staying. The team were so close to finding him, Jay anger was starting to build up again. Jay couldn't wait to come face to face to Phillip, he wanted to make Phillip pay for what he had done to his brother.

Jay was deep in thought when Mouse called him over. "What you got Mouse?" Jay questioned.

"I've managed to access the GPS data from the car, there's been 13 visits to a foreclosed house 10 minutes away from Will's apartment that must be where he's staying. Do you want me to fill the rest of the team in?" Mouse explained.

"Good work Mouse, don't worry I'll fill them in." Jay replied.

Jay lied to Mouse, he wasn't planning on filling everyone in on the latest development. Jay quickly headed out of the district before anyone could notice he was gone, he only had one plan in mind and that was to find this prick.

20 minutes later Mouse headed upstairs to the bullpen, as he got there everyone was up there working away on their computers. "What are you guys doing here? Jay said he was going to fill you all in?" Mouse questioned very confused.

"What are you on about Mouse?" Hailey looked back at Mouse.

"I found where Phillip was staying, I told Jay and he said he was going to tell everyone." Mouse trailed off, now realising that Jay had lied.

"Shit, he's gone after Phillip by himself. Everyone get vested up and Mouse text us that location." Voight demanded, everyone jumping into action.

Jay pulled up to the foreclosed house, he spotted the stolen car down the side of the house. Jay parked up just up the street from the house, as he approached the house Phillip was leaving the back door heading for the car.

"Don't move or you die." Jay warned as he pressed the barrel of his gun against the back of Phillip's head. Jay handcuffed Phillip, not taking his gun away from his head. "You're going to do what I say and if you don't you'll regret it. Now you're going to walk back towards the house." Jay threatened as he led Phillip towards the back of the house.

As they entered the house Jay handcuffed Phillip to a wooden chair in the corner. Jay was wearing all black clothing, his hoodie covered his vest and he had covered his face with a balaclava, Phillip had no idea who was taking him hostage.

"Who the hell are you?" Phillip questioned.

"That's something you don't need to worry about." Jay replied. "You made a big mistake and now it's time to pay." Jay threatened just before he struck Phillip with two firm right handed punches to the face, instantly drawing blood from his mouth.

The more Jay looked at Phillip the angrier he got, he was raging inside, he was ready to blow and Phillip was about to feel the full brunt of Jay's anger. Jay's anger only increased as Phillip spat on him, Jay delivered many more punches to Phillip's head. After many strikes to the head Jay stopped, Phillip's nose was definitely broken, one of his eyebrows was split and blood was gushing out of many different cuts on his head.

"This is what happens when you go after my brother, its different when you're on the receiving end of a beating isn't it." Jay was enjoying toying with Phillip, he was getting great satisfaction from getting revenge for his brother.

"Oh I see how it is, you're Jay aren't you. That brother of yours is lucky to be alive, don't worry I'll go back for round two and next time both he and Natalie will pay for what they did to me." Phillip snapped back.

Jay's blood was really boiling now, even though Phillip wouldn't be able to touch Will and Natalie in the future but hearing the threat really pissed Jay off. Jay kicked Phillip in the chest, the chair failing over so Phillip's back was against the floor.

"You go anywhere near Will and Natalie in the future I will hunt you down and put a bullet in your fucking head." Jay threatened as he pushed the barrel of his gun against Phillip's head.

Unknown to Jay, the rest of the team had arrived at the house and surrounded it. Hailey had seen Jay's truck parked up and was now worried about what they were going to find when they entered. As they were set up at the back door they herd part of Jay's threat. "I will hunt you down and put a bullet in your fucking head."

"Jay." Hailey called out as they entered the house. Jay came into view as they moved through the house, he was hovering over Phillip's seemingly lifeless body, his black gloves were covered in blood. "Jay, are you alright?" Hailey came up to Jay, worry spread across her face, inspecting his body with her eyes for any signs of injury.

"I'm fine Hailey don't worry." Jay reassured a worried Hailey, he wanted to give her hug but didn't want to cover her in blood. "Voight, you might want to take care of him." Jay pointed to Phillip who was still handcuffed to the chair.

"Are you seeing this officers, this man attacked me for no reason." Phillip spoke up.

"You've got some nerves on you, you're luckily to still be alive. When you attacked Will Halstead you attacked all of us, so it's your choice now whether you want to leave this room alive or in a body bag." Voight threatened Phillip as he stood over him, Phillip soon shut up. "Call an ambulance for this scumbag." Voight continued.

"Jay go home, we will sort out his arrest and everything else, Hailey you go to." Voight ordered. The two detectives agreeing and heading home.

The drive back to Hailey's apartment was a quiet one, both of them waiting for the other to say something. It wasn't until they got home and relaxed on the couch that one of them spoke.

"I'm sorry Hailey, I couldn't stop myself." Jay looked towards Hailey sheepishly to gauge her reaction.

"I'm not angry Jay, that prick got what he deserved. I was just worried about you, you could've at least told me what you were doing." Hailey softly spoke.

"I know I should've and I'm sorry that I didn't. As soon as Mouse told me where he was staying I just felt like I needed to end this. He attacked my brother and didn't want to get you involved in anything that could put you at risk." Jay explained. Jay motioned for Hailey to cuddle up close to him, something which she quickly obliged to. She was quickly tucked into the side of his body, her head resting on his chest.

"Do you remember what I said about the break room being the place where I feel in love with you?" Hailey broke the silence.

"Yeah." Jay replied hesitantly, unsure of where she was going with this.

"I think that was a lie, being in that break room only increased the need to be with you. I think the moment that I fell in love with you was during the case that involved Booth. The lengths that you went to during that case to make sure that I was safe was more than anyone has ever done for me before. I think I tried to push those feelings away because I was scared." Hailey explained.

"What were you scared of?" Jay questioned softly.

"I don't really know. I guess I was scared that you didn't feel the same way or something like that."

"Hails, I've loved you for ages. I wanted to tell you that on so many different occasions before but something always got in the way of that. But now we are together and I'm the happiest I've ever been in my life and that's all down to you." Jay spoke, Hailey blushing slightly hearing Jay's words.

"I love you Jay."

"I love you too Hails." Jay replied as he kissed her forehead. The two of them relaxing into one another.

Rojas arrived back at the apartment later that evening. She couldn't help but smile when she saw Jay and Hailey cuddled up together on the couch fast asleep. She covered the happy couple in a warm blanket before heading up to her bedroom, quickly falling asleep herself after an exhausting day.
