Back with another one! Thank you ALL for your lovely reviews and comments!

Cause I want you, you, you
Me, me, me, together
Oh, I want you, you, you
Me, me, me, forever

"Are your ready?" Jay looked up startled, seeing his brother, decked out in best man attire, standing at the door of his room.

"Ready as I'll ever be." Jay nodded, heart pounding in his ears. He wouldn't be surprised if Will could see his heart beat out of his chest like in those cartoons they used to watch as a kid.

"Could've fooled me bro." Will laughed and nudged him. He had been watching his older brother pace up and down the room muttering to himself over and over again.

"Ha. Ha. I'm nervous that's all."

"You are not getting cold feet are you? Because I swear to god if you are I will-"

"Relax Will," Jay stopped his brother mid rant, "I'm nervous she is having second thoughts. I'm also nervous I will screw up my vows, but that's a whole other issue."

"Okay, now if that's what you really think, you must be stupider than I thought you were." Will replied with a roll of his eyes.

"I don't doubt her, I really don't. I'm doubting my love for her, or her love for me. I'm also not doubting the fact that I know she wants to spend her life with me. But I am worried about the possibility that she thinks she's making a mistake on marriage. I know her and commitment, and I also know about her childhood. She has run from commitment at every chance, and marriage is the biggest commitment out there."

"Yeah, except she is marrying you, Jay. You already said you know, but she loves you. She cares for you in a way I've never seen anyone care for their loved one before. You are the different factor in all this, because you have shown her what it's like to have someone there waiting, and someone there to pick up the broken pieces and fit them together again. To her, you are everything and that's the different denominator there."

Jay looked over at his brother in surprise, "When did you get so poetic Humpty Dumpty?"

"Ha. Ha." Will slugged Jay on the arm. "Seriously though, I can see it Jay. Also not to mention my fiancée is also best friends with her, and Nat tells me everything."

"Uncle Jay!" Owen comes charging through the door, the sound of it opening just enough for Jay to steady himself as he caught Owen in a tight hug.

"Hey bud, you good?"

"Yes Uncle Jay, Adam told me to come up here because the limo is here! It's so cool! Let's go!" Owen took his Uncle by the hand and practically dragged him out the door. While he loved Will, he absolutely adored his Uncle Jay and was taken to him immediately when Nat and Will first introduced him. Jay was the cool uncle, and everything he did was amazing, a fact that Jay never lets Will forget.

"Wait, do you have the most important thing right now?" Jay quickly asked. Owen was also the ring bearer.

"Of course Uncle Jay. I couldn't loose something so valuable. It's right here." Owen patted his jacket pocket, placing on a solemn face. Jay ruffled his sandy blonde hair.

"Okay, bud, let's go!"

Across the city, Erin was getting ready in the bridal room. Her bridesmaids fussing over at every chance.

"Okay, so everything has been delivered, the cake is sitting in the fridge right now, the flowers have just arrived. The guests are starting to arrive now as well." Kim listed off the things in her head, while Erin's childhood best friend Annie, was fluffing around with her dress.

"Oh and Will's just texted me saying they've arrived and in the other room." Natalie chimed in.

"Is he as nervous as I am?" Erin questioned with a chuckle, knowing her fiancé all too well.

Natalie smiled, "I think you're doing pretty well right now. I was a wreck my first wedding."

"It's composure. It's taking all my training right now to not break down. I'm a complete wreck on the inside. Things are jumping around in there, that are not supposed to jump." Erin paused a moment and moved to grab the flutes of champagne on the table, handing one out to each of her bridesmaid. "I want to thank you all for what you have done. You have helped plan this wedding into something beautiful and magical, and I'm sure I can speak for both Jay and myself that we are so grateful and appreciative of everything. Thank you for helping me not turn into bridezilla, and being there for me at every step fo the way. So cheers to you!"

The four clinked glasses and Kim took the opportunity to bring out her phone to start grabbing selfies. She was self appointed photographer. While Erin and Jay had hired actual photographers for their wedding, Kim took it upon herself to film and capture everything else, from planning up until the actual day stating, "The wedding photos always take too long, and this way, you have another perspective."

"I guess everything is on schedule, has everyone arrived already?" Erin asked.

Natalie left the room to check and came back a few minutes later. "The officiant just arrived too, so I think we're set, as long as you are?"

Erin opened her mouth to answer when a crash followed by several curses was heard from behind. The three turned around to find Annie cussing, the champagne that was in her hand scattered in pieces on the floor.

"Annie what happened?"

"Just dropped the stupid glass on the floor, be careful!" Kim grabbed Annie's hand and helped navigate her through the broken pieces, while Erin knelt down to pick them up.

"Erin! Use gloves!" Natalie's warning was too late, because Erin felt something sharp pierce her arm and she looked down. A glass shard was jutting out from her forearm, blood trickling down. She wasn't paying attention to what she was doing, and somehow jabbed herself with a piece of glass that had somehow landed on a nearby rug, standing up.

Natalie examined the cut, "It's deep and will need stitches. I can do it here, but only if you don't mind." Kim had run off to grab a first aid kit.

Erin shook her head. "I've dealt with far worse. Stitches aren't going to ruin my wedding day for crying out loud. Besides if this is the only drama I'm facing today, I'm good with that."

Kim had returned with a first aid kit, and Natalie opened it, cursing at the lack of equipment inside. Neither her nor Will had driven, so they didn't have their bags with the emergency kits.

"Okay, Kim I'm going to have you compress this to try and stop the blood flow. Erin be careful because it might get on your dress, and it'll stain. I'm going to find someone to help me and get some equipment to stitch it up."

"Don't get Will, because Jay will figure out something's wrong, and I don't want him to worry and freak out more than he is."

"If I don't get Will though, that might most likely scar. ER docs aren't the best at stitches and Will used to be in plastics. He'll be a lot better."

Erin shook her adamantly, "No definitely don't get Will. I don't want to worry Jay. Just please anyone else. We've invited so many people from the firehouse and Med that there is bound to be somebody else. Maybe Sylvie, get Sylvie." Out of everybody else, Erin was closest to Sylvie. Aside from her PD family, Erin worked the most with her, and Sylvie had patched Erin up in the field more times than she can count.

Natalie sighed, "Fine. I'll be quick, I'll try find Sylvie." She turned to open the door when Hank Vought suddenly entered.

"Everyone is ready and waiting for you Erin," He stated in that gravelly tone of his, that is until he looked up and realised the situation in front of him.

"Erin, what did you do?" Hank stepped forward to investigate his foster daughter's arm.

Erin smiled ruefully, "I'm fine Hank, though you may just have to be careful when you walk me down the aisle later."

Hank shook his head, "Always getting into trouble and always needing to be patched up."

From behind, Natalie spoke up, "Actually, Hank, can you do us a favour? We need some equipment to give Erin some stitches and there's none here. Can you go out grab needles, thread, a lighter and forceps." Natalie quickly listed.

Hank nodded and swiftly left the room, Natalie following soon after.

When they came back, Kim was still-compressing the wound while Annie was trying to arrange the dress in a way that blood won't get on it. Hank arrived back, having found a suture box and Natalie arrived with Sylvie in tow.

"Hey Erin! Congratulations!" Sylvie beamed wide at her. "Y'know I've fixed you up almost everywhere, and I can safely say I didn't think I'd be doing it at your wedding though."

Erin let out a dry chuckle, "Well when Natalie needed somehow to help her, I immediately thought of you because I couldn't let you miss out on this."

Natalie and Sylvie both got to work. Hank having soon gone over to Jay's room to distract the groom. "Wait, how are you distracting everyone? I'm sure people are wondering why we haven't started."

Sylvie grinned, "Matt's entertaining them."

Erin's eyebrow raised high, "Matt? You mean Captain Casey? When did you start calling him Matt? And I don't see him entertaining a roomful of guests."

Sylvie's smile turned shy as she assisted Natalie in suturing up the wound. "Well he couldn't say no when I asked."

Erin's lips twisted into a huge smile when she understood Sylvie's comment. "I'm so happy for you! You finally went for it huh?"

Sylvie simply nodded as Natalie announced she was finished. "It'll do for now. If you want, we can get Will to take a look later to make sure."

Erin shook her head as she grabbed her bouquet. Annie rushed off to grab Hank and Kim handed Natalie hers. "Nah let's get this show on the road!"

Everyone in the room stood up as Pachelbel's Canon wafted through the room. The doors opened, and both Hank and Erin stepped through, walking in perfect sync with each other.

"Ouch, careful Hank, please." Erin muttered as Voight accidentally brushed his hand over her wound.

At the other end of the aisle, Jay took a breath before turning around, jaw dropping at the sight of his Erin walking down to him. She was stunning and it took his breath away. As she moved closer, Jay could feel his eyes start to well with tears as he was one step closer to his happily ever after.

As Hank handed Erin's arm to Jay, and he took it, he noticed the blotchy, red mark that ran along her forearm. He looked at her in shock but she shook her head, silently telling him to leave it. As the officiant spoke, all Jay could think about was how and why and what happened to Erin. So much so that he nearly forgot to say his vows. He was broken out of his reverie when the officiant cleared his throat and he realised everyone was looking at him.

"Oh sorry!" Jay flustered, fumbling with the piece of paper in his hand. "Erin. From the moment I met you, I knew you were something special. But it wasn't until I got to know you and understand you, that you became special to me. You were frustrating and maddening. You never let me drive and made me feel like a house husband." Erin let out a chuckle at this. "But you challenged me, in a way that made me want to be challenged like that for the rest of my life. I thank God everyday that you came into my life and chose me, and accepted me with all my flaws. I told you a long time ago, that I wanted you and me together, forever. I'm so happy that it is finally coming true." Jay finished with a smile, staring directly into Erin's eyes which was starting to pool over with tears.

"Now Erin, would you like to say your vows?"

Erin took a deep breath and let it out. "Damn you Jay Halstead, I knew you'd make me cry." Laughter rang through the room and Erin turned to look at them. "I'm being serious right now, I actually wrote that as the first sentence." Erin showed Jay the piece of paper and Jay nodded.

"She's right guys."

"The first day I met you, you were just some annoying arrogant detective who'd I have to show the ropes of working at Intelligence. I was frustrated everyday because you act all cocky as though all it was to you was to get into my pants. But it wasn't until we worked that first case together when I realised for what it was, an act. You're not actually cocky or arrogant. While yes, you exude confidence, you are kind hearted, generous and seriously humble. You care greatly for the people around you and for the people we meet on cases. I'm so thankful that you came to care for me too. I'm grateful everyday that you decided to breakdown those walls of mine, pull me out of that hole I was digging myself into, and for being the light at the end of my very dark tunnel. You are my present, my future and my forever."

By this time, the couple was crying, and both Natalie and Will stepped forward to offer them tissues, causing awwws and ahhhs to resonate through the room.

The officiant announced for the rings and Owen stepped up, two rings precariously balancing on a pillow. As they said their final I will's and slipped the rings on the respective finger, Jay couldn't wait any longer and stepped forward to crash his lips to hers in a passionate kiss.

The officiant stepped back to give the couple their moment while clapping, hollering and wolf whistling came from the crowd. Each of Jay and Erin's loved ones happy that the couple finally tied the knot. As they came apart for air, Jay rested his forehead against his wife's.

"You and Me. Together. Forever."

Done! Wow, this took so much longer than expected. This must be my longest OS yet. I hope you all enjoyed it! Please leave a comment/review about the wedding. I'm very unsure if I had written the wedding part correctly. But I do know that many people have now gone from 'I do's' to 'I will's'.

Also please let me know if there are any mistakes. I finished writing at 2.30am so I'm extremely exhausted. Thank you for reading!
