Jay took a shower and put on his dress pants and tee shirt then carried the rest of his suit downstairs to put on last minute. He knew Erin would take some time to get ready so he left her the room and bathroom while he sat in the living room watching sports center.

An hour and a half later it was time to leave. "Lindsey come on we have to leave now or we'll be late!" he yelled form the bottom of the stairs.

"I'll be down in 30 seconds!" she yelled back. Jay smiled to himself knowing that his partners idea of thirty seconds was actually somewhere between five and ten minutes. He paced back and forth in the foyer keeping an eye on his watch. When he heard footsteps on the stairs he turned around claiming, "That was more like eight minutes…." his last few words trailed off. Jay had always known that his partner was good looking, and the night of the reunion she looked hot, but this was different. Jay's eyes grew big as he watched her walk towards him.

"What is someone behind me holding a gun to my head?" Erin said looking back over her shoulder with a confused expression on her face.

Jay looked down at his shoes smiling. "No. It's nothing…It's just you…..You look really beautiful." He finally said.

Erin smiled coyly biting the inside of her cheek. "You clean up pretty nice yourself

Halstead."

They pulled into the parking lot of the church. Jay looked over at her in the passenger seat "you ready for this?" he asked.

"Yup, lets go lie to people in a church" she joked. "You know were going to hell right?"

Jay laughed and then exited the vehicle. Erin waited for him to open her door like she promised she would. When she got out she took his hand and smiled. "Lets do this."

The pair entered the chapel hand in hand. They took a seat next to his parents just as the organ began to play. As the ceremony went on Jay never released her hand. He used the ball of his thumb to draw small circles on the back of her hand. As the bride and groom said their vows Erin could feel Jay take multiple quick glances over at her. For some reason this made her feel shy. She could tell that her cheeks were blushing.

She couldn't stop thinking about what moments had been real, and what moments had been fake between them. Was her partner a surprisingly good actor, or did he have honest feelings for her? It was driving her crazy. She was going over the events of the last two days in her head for the 100th time when everyone started to stand. The ceremony was over and it was time to head to the reception hall.

The second they arrived Erin headed straight for the bar. "I need a drink" she told Jay. Her tone was serious and Jay had noticed that she was exceptionally quiet the whole drive over. She didn't even tease him once.

"Sure. Are you ok?" he asked looking concerned.

"Yeah fine" she said before knocking down the first drink letting the liquor burn her throat.

"Whoa, slow down there slugger. The bar will be here all night." He said while wondering why her mood had changed so suddenly.

She glared at him. "Lindsay what's going on? Did I do something wrong?"

When she heard him ask about her and saw the concerned look on his face she immediately felt guilty. He hadn't done anything wrong. She was just confused and taking it out on him. She promised to be a good fake girlfriend and she intended on keeping that promise.

"Sorry. No everything fine." She said with a smile. "Lets go find where we are supposed to sit." She took his hand and searched for their table number.

After that Erin loosened up. Jay's family was extremely welcoming. A group of his aunts and cousins that had drank way to much told her funny childhood stories about Jay, gossiped about other family members, and completely pulled her into their little group.

While Erin was talking Jay went to the bar to get them another drink. His dad walked over and patted him on the back.

"She seems good for you Jay. I really like her."

Jay looked over towards Erin, who was laughing at a joke his aunt had told.

"Yeah I do to." He said with a smirk.

Just then Erin looked up and saw Jay and his dad looking her way. She flashed him a smile and he nodded back.

"I better get over there dad, I have a feeling they are telling an embarrassing story about me." He said with a laugh.

"Do you mind if I steal her away for a few minutes ladies?" he asked placing a hand on Erin's shoulder.

"You too love birds go on ahead." One of his aunts slurred in her drunken state.

They walked towards the dance floor just as a slow song began to play. She wrapped her arms around his neck and he rested his hands on her hips, rocking back and forth with the music.

"What kind of dirt did they give you on me?" Jay inquired.

Erin laughed, "oh no, I'm saving these jems for the perfect time. Sorry Halstead."

Just then Jays eyes got wide, and a nervous expression over took his face. Erin followed his stare to a small group of girls just entering the party.

"Which one is she?" curiously Erin asked.

The question snapped Jay out of his thoughts. "Huh?...What?...Which one is what?"

"I'm not stupid Jay. One of the girls that just walked in is an ex right?"

"Red dress." He answered

Erin raised an eyebrow "really the blonde? Huh." She paused "So is she the reason I'm here?"

He looked back at Erin "No, I didn't even know she was going to be here. Last I heard she was living in Miami now."

"Oh, well do you wanna make her jealous?" Erin asked with a devious smirk.

Jay laughed. "I got this." She said before he got a chance to answer her previous question.

She took a small step closer so their bodies were pressed together.

"Now put your hand on my ass."

Jay furrowed his brow in confusion. "Come on Halstead. Trust me I know what I'm doing." He did as told.

She spoke again, "Alright now don't make eye contact but see if she's noticed yet."

He glanced up "I think she's looking…Shit she's walking this way" he whispered frantically.

"You sure she's looking?"

He quickly looked up again "Yeah definitely sure."

The last word had barely exited his mouth when Erin pressed her lips to his. Jay was in complete and utter shock. It took him a few seconds to begin kissing her back. At first the kiss was light and sweet, then it grew heavier and sexier. Erin slid her hands down onto his chest before pulling back. She smiled nodded toward the girl "I'll be in the bathroom." Leaving him to talk with his ex.

Erin returned about 15 minutes later. "So it worked right?"

Jay nodded "Yeah"

"Good. Told you I knew what I was doing. Now lets go dance. I love this song."

As she started to lead the way Jay grabbed her arm. "I really didn't know she was coming, and she has nothing to do with why I invited you. I just want to make sure you know that."

"I know Jay." She replied reassuringly. "Now lets go the songs almost over!" she said pulling him to the center of the dance floor.
