A/N: I wanted to write about their first "break-up". I don't why they would ever break-up, but even the best couples do at some point in time. I'd say I hope you enjoy, so I'm gonna say I'm not good at writing sad scenes fyi so if it's bad I did warn you.

"You went behind my back! Why would you do that? They're under my rules NOT yours. It ain't Chicago." Olivia practically screamed.

"Olivia, two coworkers aren't allowed to date! You're gonna tell me you would've allowed it?" Hank yelled back.

"Yes, I would have allowed it. They both knew from the start when we were sneaking around and they said nothing. Hank, you had no right to tell my detectives what they can and cannot do." Olivia stated.

"If you had told me that I wouldn't have threaten them. Now, whoever they chose to stay has a job while the other doesn't." Hank mumbled, realizing his mistake.

"You inconsiderate asshole! They're MY people. I don't care how you run Intelligence, but don't try it with my squad." Olivia said through gritted teeth.

"I'm not an asshole for telling them that. In house relationships are tricky! The moment they break up it will be messy." Hank said.

"Say that to two of your detectives." Olivia scoffed. They both knew who she was talking about.

"We don't have proof they're in a relationship." Hank responded.

"I guess that means you don't either." Olivia said, full of cockiness.

"This is ridiculous. Why am I arguing with you? When you realize I'm right you know where to find me." Hank said.

Hank walked out and went straight to the airport. He was supposed to leave in a couple of hours, but he decided that it be best if he stayed far from Olivia. They both needed to clear their heads. This was their first argument and it was over her two detectives kissing in public.

He also hated how she pointed out Halstead and Lindsey. He hated to know that Erin liked Jay and it was vice versa. Boy, did he want to strangle Jay, but he was a good detective. If he was going back to Chicago no one needed to know that Olivia and him were done.

Olivia knew something was going on with Amaro and Rollins. Then at some point they were no longer 'nice' to each other, but then they were again. She turned a blindside to them dating, so she had a team working together smoothly.

They were both responsible detectives and it took awhile to catch on. Their small jokes, looks and gestures suggesting much more than co-workers. Even when she should've said something she didn't because it reminded her about her previous relationship.

She needed to call them both and tell them not to worry after she called Hank. Maybe she didn't have to call him…after all he did walk out of her apartment. Olivia wasn't gonna waste her breath on an inconsiderate asshole. It was her unit not his.

Hank was at the airport in Chicago when he was about to call her. It was a habit ever since he first went to Manhattan. He called Erin to come and pick him up. It annoyed him that Olivia knew something about Halstead and Lindsey. He had a somewhat of an idea about them. There were certainly some points she had and if she was right he wanted to know. He wasn't a big fan of being left out of the loop, so for Olivia to know something it rubbed him in the wrong way.

Hank wasn't a big fan of apologizing, so if she was right all her points would've been proven. If he apologizes to Liv that meant an apology to Amaro and his significant other, Rollins. Olivia was right when she said it wasn't his unit because if they were they would've been fired at that moment.

It wasn't 'till they were in his living-room did he remembered why he called Erin. He noticed the way she tried to hide the fact that she was nervous and hiding something. He offered to order food. The conversation was happening now or else.

"Erin, is there anything you want to tell me?" Hank asked.

"Is there anything you want to tell me?" Erin asked back.

"Answer the question or I'll have you sitting at a desk 'till I get an answer." Hank warned.

"Ok, I'm gonna need some work to do because if I finish my DD5's and there's no work on my desk, I'll leave for the rest of the day." Erin threatened back.

"Don't worry kiddo. You'll have work to do." Hank replied.

Erin nodded and said, "Olivia called, she told me you left some work papers at her house. Mentioned something about mailing them over."

"Call her back and tell her I said to send it to Intelligence." Hank said.

"Ok…did something happen between you two because I mention her name and you got upset." Erin said cautiously.

"Nope, nothing you need to worry 'bout." Hank answered casually.

"Ok, whatever you say." Erin said.

Hank was about to grab another beer when it hit him. He never brought work when he went down there unless it was work related. Erin was trying to get him to say something by being slick.

"Erin what do you know?" He asked.

"I knew something was up when you called and it definitely wasn't about Jay and I." She responded.

"Just tell me something. Are you and Jay dating?" He asked.

"You want the truth?" She asked.

Hank nodded, while looking for his wallet. He payed and shut the door on the delivery guy's face.

"Honestly, I don't know. One minute he wants to date me and the next he's worried about you mentioning something about keeping it in his pants." Erin ramble on some more about her and Jay's complicated relationship.

Hank was fucked badly. Olivia was right, there was a thing between Erin and Jay and he needed to apologize to Olivia fast. She was always right about something. Walking out on her and slamming the door was wrong and very stupid. How could he be so dumb?

He told Erin he needed to make a phone call and to make herself comfortable in the living-room. Hank went upstairs to his room. He searched for her phone number and called her number. At first she didn't answer, but the second time she did.

"Hank?"

"I'm really sorry Liv. You were right about everything and to be highly pissed. I shouldn't have talked to Rollins and Amaro. You're right they aren't my detectives and definitely not my squad. Forgive me?" Hank pleaded.

It was silent for awhile and then she said, "Hank, next time you pull a stunt like that and it will take awhile for me to forgive you and I'll have you suffer."

"Deal." Hank replied.

Hank knew not to mess up again. Olivia meant what she said to him and he knew. He wasn't gonna make anymore mistakes. After all he did learn his lesson.

A/N: If you were mad at me at some point in this story I'm sorry. I kinda wanted to write that. I'm never gonna write a chapter like that again. It was probably the hardest because some parts didn't come to me as easily as most which annoyed me. My next chapter might be about Venson and Linstead. It won't be a very nice one, well actually it depends. Anyways 'till next time.
