Author Note: I'm glad you guys loved Mouse in the last chapter. I also felt Chicago PD really dropped the ball with Mouse. He left the show and it was like he never existed. But I wished they brought his character back. Anyway I hope you guys enjoy this next chapter.

Chapter 16: The Wedding

Laughter erupted from the table in the corner of the restaurant. The two couples sat at the table enjoying a nice evening out. Erin takes a sip of her wine as Jay and Mouse trade stories about their time together in the Rangers. Jay didn't talk about it much even when they were together before but seeing him being carefree and remembering the good times brought a smile to her face. She looks over at Mouse seeing the carefree look on him also and she smile. She watches as he glances toward his fiancé and she's never seen him so happy. When he left all those years ago he was haunted but seeing him now there is a peace to him.

She looks over at Rachel, Mouse's fiancé and she sees the pure love in her eyes for him and she's happy that Mouse found someone that loves him. "Okay, Okay." Erin places her wine glass on the table. "As much as I'm loving this stories of the two of you, I want hear more about how you two met." Erin says pointing at Mouse and Rachel.

Mouse looks at Rachel with a smile on his face. "We met overseas."

Rachel takes over and continues. "I'm a doctor."

Jay and Erin look at each other impressed. "Good job Mouse." Erin says with a smile.

He lets out a laugh as Rachel continues. "I'd met Mouse 5 months into my stay with Doctors Without Borders. He was just so kind and generous." She looks over at Mouse with a smile. "It didn't take me long to realize that he was the one."

"Wow." Jay replies taking a drink. A smile appears on his face. "You're a doctor, who's working for doctors without borders and you settled for this guy." Jay says jokingly.

Erin slaps jay arm. "Ow."

"Hush, you big baby." Erin says with a smile.

"Gee, thanks buddy." Mouse replies taking a drink.

"You know I'm kidding. I'm happy for you guys." Jay says as he grabs his beer and takes at drink. "You got yourself an amazing women here."

Mouse and Jay click their beer bottles together. "Thanks, man."

Jay turns his attention toward Rachel. "So, Rachel how did this guy propose to you?"

Rachel and Mouse both look at each other and start to laugh.

"What? Are we missing something?" Jay says looking at Erin and then back at Mouse and Rachel.

Mouse shakes his head. "Nothing."

Rachel smiles. "Greg's proposal wasn't exactly planned." Rachel laughs. "He actually blurted it out when I told him that I was leaving since my commitment with Doctors Without Borders was over."

"Hey. I was caught off guard but I had a proposal planned but sometimes plans don't work."

Erin looks over at Rachel. "So, what did you say when he blurted it out."

Rachel laughs. "I was in shock. Then I grabbed him and kissed."

"I guess sometimes spontaneity pays off." Erin says as she takes a sip of her wine.

"It definitely did and I couldn't ask for a better proposal." Rachel leans over and gives Mouse and sweet kiss.

Erin places a hand on her chest. "Aww, you two are too cute." She leans her head on Jay's shoulder and he gives her a quick kiss on the head.

"I didn't get to ask you before but when is the wedding." Jay asks as he takes a drink.

Rachel glances at Mouse and says, "It's actually in a couple days."

"Wow. That's fast." Erin says in shock lifting her head up from Jay's shoulder.

"We know, but it's not going to anything big." Mouse replies. "We wanted to do it at the court house but Rachel's parents were against it.

"I'm an only child and they always thought I would have a big wedding. My mom always pictured us planning a huge church wedding followed by a big reception." Rachel says. "We came up with a compromise. Instead of us getting married at the courthouse or having a huge wedding. We would have a small ceremony and nice reception with close friends and family."

"I can't imagine planning a wedding in the short period of time. If you need any help just let us know." Erin offers giving Mouse and Rachel a smile.

Rachel looks over at Erin. "Erin, there's actually want to ask you something."

Erin looks around the table and her eyes land back on Rachel. "Okay? What's up?"

Rachel takes a breath and begins to ramble. "My best friend can't make it to the wedding and since it's a small wedding we're only having a best man and maid of honor. And I don't really have a lot of other friends and I know this is probably a lot to ask especially since I just met you." Rachel pauses and begins wringing her hands together. "What I'm trying to get at is will you stand up with me and be my maid of honor."

Erin looks at her in shock. "Umm…wow. I don't know what to say."

"I hope you say yes. I really don't have anyone else. You and Jay have been a big part of Mouse's life and it would mean a lot to both of us." Rachel replies pleading with Erin.

Erin lays her hand on top of Rachel's. "I'd be honored."

Rachael gets up from her chair and goes to hug Erin. "Thank you. Thank you."

Jay knocks on Erin's apartment door. He took a breath and ran his hand down his Army Ranger uniform waiting for her to answer. He plastered his best pretty boy smile on his face and gave himself a final once over as the door to the apartment opened.

"Hey gorgeous." Jay says as lifted his head up when he finally looks up he is shock at who is standing there.

"Expecting someone else Halstead." Hank says with a smirk on his face.

Jay clears his throat. "I thought you were, Erin."

"Relax." Hank says letting out a laugh. "Yeah, I figured but she is still getting ready." Hank moves aside to let him into the apartment. "She should be out in a minute."

"Hey, kiddo looks who's here." Hank says.

Nadia looks up from the tv and sees her dad and shouts, "Daddy." She gets off the couch and runs over to him.

Jay grabs her and lifts her up into his arms. "Hi, munchkin."

"Hi, daddy." She says with a smile. "You look handsome, just like Poppa."

Jay smiles and looks over at Hank who is dressed in a suit. "Thank you." He places a kiss on her cheek. He looks down at the pretty dress she is wearing and says, "You look beautiful."

Nadia gets a huge smile on her face. "Thank you." She says with all the politeness in her voice. "Mommy and I picked it out for the wedding."

"We'll you both did a good job." Jay says as he places her back on the ground.

Nadia smiles. "Wait to you see Mommy."

Jay laughs. "I hope she hurries up or we're going to be late?" Jay says glancing down at his watch.

Erin enters the room. "I'm here. So you can calm down Halstead." Erin's says in her raspy voice.

Jay's lifts his head up at the sound of her voice. His eyes finally makes contact with her and he is rendered speechless. Erin is dressed in a black sleeveless Maxi dress and her dark falls to her shoulders in lose beachy waves.

Erin looks at him with a smirk on her face. "So, how do I look?"

Her voice brings him out of his fog. "You look absolutely stunning."

Hank gruff voices speaks next. "I have to agree with Halstead, you do look stunning."

"Thank you." She says with a smile. "I'm loving the compliments."

"Mommy you so pretty." Nadia says staring up at her.

Erin looks at her daughter and says, "So, do you sweet pea. Now remember you are going to come to the church later with Poppa because Daddy and I have to be there a bit early."

"Got it." Nadia says.

Erin looks around for her purse. "Okay. I just need to find my purse and grab my coat and then we can go."

"I'll grab your coat." Jay replies.

Erin nods her head as she spots her purse on the counter. Jay comes back with her coat and helps her into it. The say their goodbyes and head out the door. As soon as the apartment door closes Jay stops and kisses her.

Erin smiles. "What was that for?"

"I've been waiting to do that since you walked into the room."

Erin moves in to kiss him this time a little bit longer.

He looks at her and says, "What was that for?"

She runs her hand down his uniform. "You just look so hot in your uniform." She runs her hand down his uniform. "I can't wait to get you out of it later." She says in a throaty whisper.

He gives her a flirty smile and places another kiss on her lips and grabs her hand. "Come on we're going to be late."

The church is full of Mouse and Rachel's close family and friends. Jay and Mouse stand at the alter waiting for the ceremony to begin. Jay looks over watching Mouse fidgeting with his suit.

He turns toward his friend and says, "Relax, man."

Mouse looks back at him. "I'm good." Mouse lets out a breath. "Just ready to get this started."

"Here comes the officiant now."

The last few guest take their sees and the music begins. The door opens and Jay breaths catches in his throat as he sees Erin standing there. As she walks down the aisle she gives Jay a huge smile. Jay returns the smile and his soon overtaken by a vision of her walking toward him in a white dress.

He is taken out of vision by Mouse hitting him. "Pick up your jaw man."

Jay lets out a small laugh and looks over at Erin who is now standing across from him with a knowing smirk on her face. The wedding procession begins and Rachel begins the walk down the aisle with her father. They stop at the end of the aisle and Mouse moves toward them and grabs Rachel's hand.

He looks over at his bride to be with tears in his eyes. "You look beautiful."

She gives him a smile. "You don't look bad yourself."

The ceremony was beautiful. Seeing them profess their love to one another brought tears to Erin's eyes. During the vows she and Jay locked eyes with each other completely lost in their own world. Before they knew it the ceremony was over.

The officiant looks at the new husband and wife. "You may now kiss the bride."

Mouse places his hands on Rachel's face and delivers a passionate kiss to her lips. He takes the kiss further as he moves his hands to her lips and dips her.

Adam yells out. "Yeah, Mouse." Laughter begins to fills the room.

Mouse ends the kiss and the officiant lets out a laugh speaks again. "It's my honor to present to you for the first time ever Mr. & Mrs. Greg Gerwitz."

Everyone stands to their feet as cheers and applauses erupts throughout the small church. Mouse lifts their entwined hands and the two up as the two of them head back up the aisle. Jay and Erin hook arms and follow the newlyweds out the church.

The reception is now in full swing and everyone is out on the dance floor having a good time. Erin is sitting down at a nearby table with Hank as she watches Jay and Nadia dancing with each other. She smiles as Jay copies Nadia's dance moves as the little girl throws her head back in laughter.

She turns her neck to show Hank what is happening. "Hank."

She realizes that Hank doesn't hear as he is too preoccupied. Erin turns her body fully toward him and sees him looking down at his phone with a smile on his face. "What are you smiling about?"

Without looking up from his phone Hank replies. "Anyone ever tell you that your nosy."

"All the time. That what makes me such a good cop." Erin grabs the glass on the table and takes a drink.

Hank looks up at her and lets out a laugh.

"So, when do I get to meet this women that's been putting a smile on your face." Erin says staring at him.

Hank ignores her and gets up from his seat and offers his hand to her. "Let's dance." She takes his hand and stands up and turns to gets ready to move them to the dance floor but he stops her. She looks back over at him.

"Soon, I promise."

She nods her head and follows him as he leads her to the dance floor to dance.

A little while later after dinner is served the DJ changes the music to slow songs. The DJ invites the newlyweds to the center of the dance floor and the two are quickly lost in their own little world. After a while the DJ invites everyone to join the newlyweds. Couples quickly fill the dance floor. Adam grabs Kim hand and leads her into the floor and he pulls her into his arms and the two begin to sway. Adam whispers something into Kim's ear which causes her to let out a small laugh.

Hank walks over to Nadia who is sitting on Jay's lap. "Would you like to dance?"

Nadia nods her head and jumps off of Jay's lap and slips her hand into her grandfather's and follows him. He places Nadia on the tops of his feet and begins dancing with her.

Jay looks over at Erin who is watching Hank and Nadia with a huge smile on her face.

"I love watching them together."

Jay stares at her with a smile on his face. "We should join them."

He gets up from his chair and extends his hand out to her. She looks up at him with a loving smile on her face and places her hand in his. He leads onto the dance floor as and pulls her into his arms. The two of them stare into each other eyes as they begin to sway to the music. Jay leans down and places a gentle kiss on her lips. As they break apart Erin looks around and then back up at Jay curiously.

He shrugs his shoulders. "I'm tired of hiding."

She smiles up at him and places another kiss to his lips. They hear Ruzek shouting behind them. "I knew it!"

They look over at him and Kim and let out another laugh.

"I told you Kim. I knew they were together."

Kim laughs. "Good job, babe." She places a kiss to his lips. "But can we get back to our dance."

Erin and Jay continue to laugh as they turn their attention away from Kim and Adam and back to each other. They once again get lost in the music and each other. Jay pulls Erin closer to him and whispers. "I'm gonna to marry you one day."

She looks at him in shock. She shakes her head to clear her thoughts and a smile appears on her face. She grabs his face in her hands kisses him with everything inside of her. She pulls back and looks into his eyes. "One day I'm going to say yes."
