Jay wasn't sure what to expect when he pulled up outside of Voight's house. He hadn't been there much, with the exception of when Voight got kidnapped or had his car blow up when Justin, Olive and Daniel came to visit. To him, that house was like the tower in the Emerald City and nobody got in without permission from the Wizard. He knew Erin had spent her teen years living in this house but really that was a "horse of a different color" now wasn't it?

He took the stairs two at a time until he got to the door. His palms were sweaty and he was breathing hard. Jay hadn't been this nervous in his entire life, not even as an Army ranger deployed to Afghanistan. His hand was shaking as he raised it to knock on the door. He knew they had time to talk as Antonio called him on his way to Voight's and told him that Olive and Daniel had come into town and Voight was taking them out for dinner.

Inside the house, Erin was in the kitchen. She was making dinner for her and Hank. Although the girl still primarily lived on takeout in New York, she did have an itch once and took a couple cooking classes. It wasn't like she could make a ten course meal but she could handle making spaghetti (even if it was a jarred sauce). She was about to drop the noodles in when there was a knock on the door. Hank didn't knock and nobody ever came by his place so that put Erin on guard. She crept towards the front door and her hand went to her hip, but she had put her gun in Hank's safe when she got to the house.

As she reached the door and was about to call out, she heard a familiar voice on the other side of the wood.

"Open the door Erin," Jay's voice said. Annoyed, Erin threw the lock and turned the doorknob. Jay stood before her, hands stuffed in his pockets.

"What the hell do you want Halstead?" Erin spat out.

It didn't go unnoticed to Jay that she called him by his last name. It always used to be that no matter how mad she was at him, she would always call him 'Jay'.

"What the hell was that shit at the District?" Jay asked, his nervousness turning to anger as she stood before him, arms crossed and looking unfazed.

"Why don't you just go back and teach your new partner some more tricks of the trade? I'm waiting for Hank and I'd like to finish dinner before he gets home."

"Voight went out for dinner. Antonio didn't call you?"

"No."

"Olive and Daniel came to town, Voight took them out. And since when do you cook? I always did the cooking?"

"Hey a girl can't live on takeout alone in New York, not that it's any of your business so go the hell away."

"I'm not leaving until we get one thing straight."

"What?"

"Hailey and I have never slept together."

"And I should care why? Wouldn't surprise me that you're banging your partner, after all you did it before."

"I'd like to think we didn't just 'bang', you know. I loved you."

"Whatever Halstead. Just got back to Upton and leave me the hell alone."

"I'm not leaving until you hear me out. Not that I owe you any kind of explanation since you were the one to up and leave, ending things with me over a text message. Yes a damn TEXT MESSAGE! But if you really must know, yeah I was with someone after you left."

Erin turned and stormed back to the kitchen. Jay closed the front door, locked it and followed her. He entered the kitchen as she was dropping the noodles into the pot.

"Hear me out Erin."

"Go home Halstead."

"No damn it. You're going to listen to me. I'm not your househusband anymore."

She turned to face him.

"The team got involved in a case a little while ago; it was with a K&R crew. The offender we liked was former Army ranger so it made sense for me to go undercover. I used his sister to get close to him; he liked to frequent her bar. Long story short, the offender got taken out in a shootout and when I went to his sister's place to tell her, she looked so vulnerable that I couldn't tell her I was a cop. I was in a bad place myself, dealing with the stories he and I had shared from our time overseas and with you being gone. So I kept up my undercover alias and I began a relationship with her. It wasn't professional and I'm not proud of what I did but it all came out to bite me in the ass at the end. She ended up being a suspect in a murder case we had and eventually she told Voight, Hailey and Ruzek about how we hooked up inside a club during a party. Hailey got her to keep her mouth shut so I didn't lose my badge. Voight made me go to therapy and my therapist helped me work through things. Made me realize why I did what I did."

As Jay finished, Erin just stood there. She wasn't sure how to take it all in. Jay was always the more 'morally sound' in the unit, next to Antonio.

"Are you done now?" she asked, trying to hide the hurt inside her by faking her anger. She couldn't believe he had done all that because of her.

"I just bared the worst part of my soul to you and that's all you have to say? When did you turn into such a cold hearted bitch?" Jay spat and that seemed to spark something inside her. Before Erin or Jay knew what was happening, she was on him and her mouth was devouring his.

Jay's hands, on instinct, went to pull her up onto the counter as they both ignored the items falling off the counter. Jay blindly reached out to find the stove burners and turned them until the smell of propane disappeared. Erin's nimble fingers went to the bottom of his Henley and began to yank it up to pull it off him. They separated long enough to remove his shirt before he was back on her. His strong arms, cradled her as he lifted her off the counter and walked her to the table, laying her down.

Jay began to pull at her shirt and Erin raised her arms to allow him to pull it off. Her hands went to his belt buckle and was about to unbuckle it when they heard a certain gravelly voice.

"That table is for eating, you know," Voight said, with Olive and Daniel in tow.
