She walked up into the bullpen with a cup of coffee in one hand and a file in the other. It was a Monday, the most awful day of the week for everyone. It was another day at work doing the same thing they do every other day, fight crime. It just didn't feel the same to Erin. She had a feeling ever since she left this morning, an indescribable feeling but a feeling. As she entered the bullpen she quickly discarded that feeling as she the guys gave her a quiet 'Good morning' as Voight was all ready to give out the details.

"Glad you showed up this morning," Voight said as he looked down at his watch.

"Sorry, I got caught up with personal things but I finished getting all the files." she replied.

Voight nodded at her and she quickly moved towards her desk. As she sat down her eyes interlocked with her partner sitting across from her. She smiled as she saw that he was already staring at her.

Before their eye linger could go on any longer there was an awkward silence followed with Voight interrupting their moment.

"If you don't mind I'd like to get started on this case." He implied to both Lindsay and Halstead causing them to turn their attention towards Voight.

"Alright, Jerry Spindell. He is the man we're looking for, he has been arrested several times for assault, drug transportation, drug use, and breaking and entering. Word on the street is that he and a group of men are working for someone in transporting cocaine from Mexico into the United States. It's been an ongoing situation in many states and he's made his way to Chicago-"

"How do you know that?" Antonio asked.

"Like I said, word on the street." He replied.

"Anyways, there's this party going on at Club Rouge and apparently that group has connections with the person throwing the party. With that said, I'm going to need the team to go undercover tonight. I want Halstead with Lindsay, Antonio, Ruzek, and Atwater together, and me and Olinksy. For now just find me as many files as you can on the people that are connected in this group before we actually go on."

They all nodded and Erin got up to go to the break room while Jay quickly followed her.

"You didn't call last night," He said as he watched Erin pour a cup of coffee

"I got busy with some things, look I hope that now since we've made everything official we don't have to call each other every single minute of every single day because that won't work for me Jay."

"I don't expect that either but you didn't talk to me for the entire day, I just wanted to make sure you're okay."

"Fair enough, how about I make it up to you. Tomorrow night, dinner at my house, I'll make you something special," she told him rather than asked him.

"Dinner? Made by you? That's a first, but I'll bring over some takeout just in case." He teased

She stared at him with one hand on her hip, a smirk on her face as he just teasingly insulted her. "Are you saying that I can't cook? Because every other guy that I met has said otherwise."

He let out a defeated sigh as she came back with a good but unexpected remark. "Well played Erin, alright tomorrow, at 7?"

"That'd be perfect. Also what does Voight expect us to do or dress up as for this undercover mission?" she said completely changing the subject as she walked out of the break room with her coffee in her hand over to his desk.

"I don't know, he wasn't very specific about it. But you better take it easy because we all know how the last undercover mission went for you." He said as he went behind his desk and leaned over to talk to Erin.

"C'mon Jay. Are you going to bring that up again? The guy caught me off guard and I was fine, you and Voight just overreacted."

"Overreacted? Erin, if it weren't for Voight and I you probably wouldn't even be sitting here right now." he fought back.

"You're right, I did have you to save me. And I'm glad you were there for me, you always are."

"It's why you have backup." He smiled at her as she moved over to her desk.

A few hours passed and Voight stepped out of the office and collected all the information from everyone.

"Okay, so here's the plan. Halstead and Lindsay are going to go in as a normal couple to scope out the place to see if anyone from that group is there. Olinsky and i will be parked out on the north end. Ruzek, Atwater, and Antonio I need you three to enter the club as well but head to the poker section or any of the private areas and listen around to see if anything is suspicious. Got it?" He asked

Everyone nodded in unison. Jay on the other hand dozed off a bit earlier in Voight's demands as he heard him say, "As a normal couple…" He smiled at the thought of them two being a normal couple, but to anyone else going into a club to end a drug chain isn't really normal.

"Hello, earth to Jay?" Erin said as she waved her hands over his face to get him out of his daze.

"Lets go lover boy, Voight wants us to head out soon." she said.

The both of them headed to the locker room to change up into something nicer to look more presentable at the scene.

Jay finished getting ready rather quickly while Erin took time, as usual, so he waited on the bench until she finally came out.

In that moment something came over Jay. He watched Erin walk out in front of him wearing a tight black dress that had a low cut showing off her pushed up boobs, it clung onto her waist perfectly and ended right above her knees. She wore black heels making her a few inches taller but still shorter than him. She had a light touch of makeup on her, the only thing that stood out was her dark red lipstick. Her hair bounced on her shoulders in small playful curls and her scent filled the air causing Jay's cheeks to redden. He stood up as he saw her make her way out but his legs became weak. Moments like these reminded him how lucky of a man he was, this woman can go from wearing a raggy T-shirt with jeans and boots, to a nicely fitted dress and still look beautiful in both attires.

"You ready?" She asked as she looked at herself one more time in the mirror to make sure everything looked good.

Jay chocked a little before he could actually form a proper sentence. "Y-yeah, I've been ready for awhile. You take a long time you know?"

"I'm sorry, but it takes time to clean up."

"You do clean up well if I must say," he said as he hooked his finger calling her to come closer to him.

"The same goes to you detective Halstead. It's nice to see you in a suit again." she said as she wrapped her arms around his neck. He pulled her into him by her waist and held her for a quick moment.

"Promise me you'll be safe this time. If anything goes wrong you tell me first before you go off acting like superwoman." He never liked to tell her what to do on the job but after last time he just wanted her to be safe and sound.

"Was I really superwoman?" she asked surprised at his analogy.

"Erin…"

"I promise Jay, no stupid stunts. Promise me you'll have my back?"

"Always."

He gave her a light kiss right before Antonio interrupted them saying that the team was heading out. Jay looked over at Erin who returned the reassuring look back. He smiled and walked out of the locker room while Erin followed behind.

The team met up in the garage as they huddled around for Voight to give his normal speech before they left.

"This mission is pretty basic and procedural. Of course, if anything goes wrong or if anyone of you senses something wrong make sure you inform the rest of us so you have back up before you go in and get yourself hurt." He said, his gaze never leaving Erin's as he was indicating this to her.

"You guys are one hell of a team and we don't know how strong this group is, but one thing is for sure, just make sure everyone that everyone remains safe."

As he said that they all dispersed into their cars and headed towards the scene.

The ride to the club was pretty quiet as both of the partners didn't have anything to say to each other. The only interaction that occurred was when Jay had his hand on the gear and Erin put hers on top of his causing him to glance over to her and give her a sly smile. He pulled over across the street of the club as he found a parking spot.

"You ready?" he asked.

"Ready as I'll ever be." she replied.
