Chapter 15 Close Call

Erin sat at her desk catching up on paperwork from a couple of their active cases. It had been a three weeks since Erin altercation with Bunny and beside from a couple of phone calls she hasn't seen Bunny. The calls from Bunny had had stopped two days ago and Erin a assumed that she had given up. She decided to keep Bunny's reappearance from Hank. She knows how he gets when Bunny is involved but she didn't want to worry him. Jay thought it was a bad idea but Erin told him that she knows how to handle Bunny and when the time came that she couldn't she would tell Hank. He reluctantly agreed.

Platt walked up the steps to Intelligence with a guest behind her. "I've got this guy here says he knows you guys." She moves aside and reveals Mouse dressed in his army fatigues.

"Hey, guys." Mouse says.

Adam was the first to go over and greet Mouse and pulls him into a hug. Hailey watches Adam and Kim greet the new comer. She stays at her desk and not knowing who the guy is. She watches as Erin gets a huge smile on her face seeing the new guy. Seeing that even Erin knows this guy it peaks her curiosity.

As Erin stands she glances at Jay's closed office door to see if he realized that Mouse was here. But as she looks into the office she see he's on the floor. She heads over to the office door and knocks. Jay looks up and signals for her to give him one minute.Erin nods her head and goes over to greet Mouse. Before she makes it over there Hailey stops her.

"Hey, who's that guy?" Hailey says as she stands up from her desk and makes her way over to where Erin is.

"That's Mouse. He used to work her as our tech guy. He and Jay are good friends, they actually served in the Rangers together. He decided a few years ago to head back to the Rangers. I'm not even sure when the last time Jay spoke to him?" Erin replies.

Mouse finally breaks away from Kim and Adam and makes his way over to Erin. He gives her a smile says, "It's good to see you Erin."

"It's good to see you too, Mouse." Erin says with a smile on her face.

He glances over at Hailey who is standing next to Erin, staring at him. "And you are?"

"Oh. I'm Hailey."

"Nice to meet you." Mouse says. Mouse turns his attention back to Erin.

He looks at her curiously and says, "Last I heard from Jay you were living in New York."

"Yeah, I was living there but I moved back not too long ago." Erin replies.

Mouse nods his head and looks around for Jay. "So, where is Jay anyway? I saw you sitting at his desk when I came in. Did you guys change things around?"

Adam pips up, "When was the last time you talk to Jay?"

Mouse turns and looks at him. "it's been almost a year." Mouse looks around at everyone. "Did something happen to him?"

"No. Jay's fine." Erin says. "What Ruzek was trying to say is that Jay has been promoted. He took over for Voight after he was shot." Mouse looks at Erin. "Jay's the new head of Intelligence."

Jay emerges from his office and a smile instantly appears on his face. "Mouse." He says as moves closer to his old friend and pulls him into a hug. "Man, is it good to see you."

"You too, man." Mouse says with a huge smile on his face.

"How have you been, man? It's been like a year since I last heard from you." Jay asks as he pulls back from the hug.

"I've been good." Mouse pauses. "The reason I'm here is because I've got some news."

They all look at him waiting to hear the what he has to say. "Well, what is it?" Kim asks.

"I'm getting married." Mouse replies. Instant shock appears on everyone's faces. "Don't looks so shock guys."

They all break out their dazes and they all began to offer him congratulations. Jay shakes his head and says, "Greg." He says as he pulls him into a hug. "I'm happy for you."

"Thanks, Jay." He says as they pull apart from the hug. "I've got something to ask you?"

Jay looks at him curiously. "What?" But before he could answer the phone rings.

Hailey answers the phone. She pulls it away from her ear and says, "Sarge, we just caught a case."

Jay nods his head at her and turns back to Mouse. "Sorry, we gotta roll."

"It's no problem I get it."

"How about me and you grab a beer tonight and catch up?" Jay asks.

"Yeah, man that sounds great." Mouse replies.

It was late and Jay was in his office finishing up some paperwork before he headed out to see Mouse. The rest of the unit had left a couple of hours ago and were headed to Molly's for the evening. He grabs his coat and as he puts it on his cell phone rings. He picks the phone up and to see who's calling and a smile appears on his face as he answers the call.

"Hey." The raspy voice on the other end says.

"Hey." He replies.

"I know your probably with Mouse but Nadia wanted to call and say goodnight before she went to bed."

"You actually just caught me before I left."

"Oh, good." She pulls her the phone away and says, "Nadia, your dad's on the phone." Erin hands the phone to their daughter.

"Hi, daddy." The little voice says as she gets the phone.

"Hey, munchkin."

"Mommy says that you are hanging out with a friend tonight and I won't see you before bedtime." She pouts.

"I am. I haven't seen my friend for a long time." He pauses. "I'm sorry I'm going to miss bedtime."

"It's ok daddy. It's good to have friends."

Jay laughs and says, "Thanks. I promise that when I come home I'll come give you a kiss okay."

"Ok. I love you daddy."

"I love you too munchkin. Can you hand the phone back to your mom?" Jay asks.

"Mommy! Daddy wants to talk to you." She yells into the phone.

Jay laughs and shakes his head at his daughter's antics.

Erin takes the phone back. "Go and brush your teeth." She says before she pulls the phone back up to her ear. "Hey, have fun with Mouse tonight and I'll see you when you get in."

"It might be a late one." Jay says.

"It's okay. I'll wait up." Erin pauses. "Jay hang on a minute."

"Okay." He says as he hears Nadia's voice through the phone.

"Mommy, Ollie peed on the floor.

Erin sighs. "I'll be there in a minute."

Hurry, mommy. It's going everywhere." The little voice says dramatically.

Jay laughs at the conversation the two of them are having.

Erin hears his laugh and says, "Jay, is not funny."

"I think it is." He says as he laughs harder.

Ugh, your daughter is being super dramatic and I gotta go. I'll talk to you when you get in. I love you." She says as she hangs up the phone.

Jay stands there in shock for a minute. This is the first time that she has said those words since she's been back and he didn't even get a chance to respond. He shakes his head and glances down at his watch and he realizes that he is running late. He pockets his phone and heads to the nearby bar to meet Mouse.

He walks in and Mouse is already at the sitting at a table with beer for himself and one for Jay. Jay slaps him on the back and takes a seat. "So, you're getting married. When do I get to meet this lady that got you to commit."

Mouse smiles and says, "Soon. She should be here in a couple of days." Mouse pauses. "She's amazing Jay."

Jay takes a sip of his beer. "I'm truly happy for you man."

"So, what did you want ask me?"

Mouse takes a drink and say, "Will you be my best man?"

"Of course." Jay says with emotion in his voice.

Mouse pauses. "I see Erin's back." Jay nods his head. "Last time I talk to you she was living in New York and the two of you haven't spoken."

Jay takes a sip of his beer and sets the bottle down. "Voight got shot a while back and it was bad. Al called her told her what was going on and she came home."

"That must have been a shock for you." Mouse says as he takes another drink.

Jay shakes his head. "What was even more shocking was I saw her and she had a kid with her.

"What."

"Yeah." Mouse looks at Jay. "So, is the kid yours?"

"Yeah. Her name's Nadia and she's the best thing that ever happened to me. But let me tell you when Erin first told me, I was pissed."

"I can imagine."

"But we worked things out and where giving our relationship another chance."

"I'm happy for you man. You and Erin always had something special and if the two of you can move passed all the pain and start again then I wish you all the best."

"Thanks, man." Jay takes another drink.

Jay doesn't get home until late. When he enters the quiet apartment, he kicks his shoes off at the front entrance. He hears the TV on low and slowly makes his way into the living room. He sees Erin fast asleep on the couch and a smile appears on this face. He picks up the remote and turns it off and places a gentle kiss on Erin's head. He remembers that he told Nadia he would come in say good night even though she would be sleeping. He makes his way to Nadia's room and quietly opens the door. Jay walks over to the bed and places a gentle kiss on her forehead and says, "I love you."

He turns and walks out of the room and closely the door behind him. He makes his way back over the couch and carefully lifts Erin up into his arms. As soon as she is in his arms she begins to stir. "Jay." She says sleepily.

"Yeah, it's me. Go back to sleep." She nods her head against his chest. He walks them into the her bedroom and places her into the bed.

"Come to bed." She mumbles in her sleep.

Jay smiles and says, "In a minute." Jay goes and grabs his sleep clothes and changes. His crawls into bed and wraps his arm around Erin and whispers, "I love you, too." And he falls into a deep sleep.

Jay is waken by someone roughly shaking his shoulder. "Jay wake up."

He rolls over and says, "What?"

"We're late that's what." Erin says. "We slept through the alarms. Nadia was the one who woke me up."

Jay jumps up from the bed. "Shit."

"I'm going to take Nadia to school and I'll see you at the district."

Jay nods his head and places a quick kiss on her lips and goes to get dressed.

Adam is standing by his desk talking to Kevin. "I'm telling there seeing each other again."

Kevin looks up at him and says, "What makes you think that?"

"Come on, Kev. There both late and they are never late. But today they both call and say there running late." Adam shakes his head. "There something definitely going on. They have been too in sync lately. Like when they were dating years ago. "

Kevin laughs and shakes his head at Ruzek. Hailey walks up the stairs to the bullpen with two coffee cups in her hands. She looks over at Ruzek and says, "You look like a kid in the candy store."

Kevin speaks up and says, "He thinks there something going on with Erin and Jay because they're both running late."

Hailey knows that the two of them are dating but she's not about to tell Adam that. She's knows they want to keep things quiet. "Sorry to bust your bubble but Lindsay called and told me that she slept through her alarm and had to drop Nadia off at school." Hailey says as she places a coffee on Erin's desk before she makes her way over to hers.

Ruzek shakes his head in denial. "There just coming up with cover stories so we won't ask to many questions. The conversation is cut short as Jay enters the bullpen. "Late night boss." Adam says as Jay strolls into the district almost an hour late.

Jay doesn't say anything, he just flips Ruzek off and heads into his office. Adam lets out a laugh and sits down at his desk.

Erin strolls in twenty minutes behind him and as soon as she enters the bullpen Adam says, "Late night, Lindsay."

Erin turns and gives him a look and says, "Shut up, Adam. I overslept."

Ruzek throws his hands up in surrender. "Seems like you and Halstead must use the same alarm." He says jokingly.

Erin rolls her eyes at him and makes her way to her desk and sees a coffee waiting for her. She looks across the way at her partner and says, "Thanks."

Hailey nods her head. "Figured you could use it."

A couple hours later the unit got a lead on suspect in one of their cases. Jay sends Hailey and Erin there to pick up the suspect. An hour later his phone rings.

"Halstead." He responds.

"Sarge, we lost the suspect." Hailey replies.

Jay cuts her off before she could get another word out. "Just get back to the district and we'll go over everything again to find out where he could have gone."

Hailey sighs. "That's not it. We're at Chicago Med."

"I'm on my way." Jay responds in a tight voice. He grabs his coat and heads to Chicago Med.

When Jay arrives in the ED he finds Hailey. She holds up her hands to stop him. "She's okay."

He sighs and lets out a breath that he didn't even realize he was holding. "What happened."

"He got the jump on us." Hailey says as she shakes her head, "There was someone else in the house with him. I got hit over the head by the other guy while Erin went after I suspect. She took one to the arm and other to the vest. Will says it looks like just a graze and he's fixing her up now."

Jay runs a hand through his hair and asks. "Are you ok? How's your head?"

"I'm fine. I was just caught off guard."

Will comes out of the room and sees his brother talking to Hailey and heads over to them. "She's fine. The bullet just grazed her. She's going to be sore from the bullet she took to the vest but you can go in and see her."

"Thanks." Jay says as he slaps is brother's arm and heads into the room.

Erin sees Jay as he enters the room. "I'm okay." She says. "I told Hailey not to call you."

Jay walks over to the bed she is sitting on. "I'm glad she did. I was worried when she told me you were here."

Erin gives him a smile and says, "Which is exactly why I didn't want you to know." She touches his arm and says. "I'm going to be fine. Will says that I'm going to be a little sore but nothing I haven't experience before."

Jay sighs in relief.

Erin sees the look on his face and grabs his hand. "Jay this is part of the job."

"I know. I know." He takes a breath. "I just needed to make sure you were okay."

Erin gives him a smile and stands up and places her hand on his face and says, "I love you." Jay looks back at her and smiles. "I know I told last night on the phone but I hung up before you could respond. I just want you to know that it wasn't a slip of the tongue I meant what I said."

Jay looks at her and replies, "Say it again."

She smiles and says, "I love you, Jay."

He leans down and kiss her passionately on the lips and says, "I love you too, Erin."
