So this was wrote to field the space between Season 3 and Season 4. Enjoy

It had been ages since Jay and Mouse spend some quality time together out of the Precinct. And Jay was glad to be in Mouse's company tonight but when Erin said that she preferred to be alone he felt frustrated. As always she was shutting down, closing herself alone in her shell and trying to solve Voight's messed up vendetta. He felt like they were heading backwards again. And he just hoped she could admit that she needed him to help her get through one more pitfall in her life. Yes her life had been full of them but now she had him to rely on, but as always she forgot about that.

"Yeah I won again!" Mouse shouted with a jump from the couch.

"Since when are you any good at Black Ops?" Jay asked, stunned how his friend had managed to win him three times in a row.

"It's a computer game man, I'm a computer technician! Don't fell bad, I'm just good, You know?" Mouse said mocking his friend.

"Stop boasting! Do you want a beer?" Jay asked, preparing to get up but Mouse beat him on that and went to the kitchen.

"I'll get it!" Mouse informed him.

"You feel very comfy in my home. Have you been spending time here when I'm out?" Jay asked.

Mouse looked at him with a closed face.

"What? You use to do that!" Jay said.

"Not since I got my life back." Mouse answered still staring at Jay. But Jay didn't seem convinced. "What? Yeah Jay all I wanted to do is come to this bunker of yours and cuddle on the couch alone, thinking about the time we spend together." Mouse said making a snort.

Jay snorted back. "I know we use to spend more time together… I'm sorry but she prefers to stay at her place and I prefer that too. So we end up to going to her place and I don't fell comfortable inviting you in there… sorry!"

"No sweat man. It's ok for me and I'm really happy that you found someone. It's good for you… But just why do you prefer to stay there, you are always so picky about your stuff?" Mouse asked.

"Exactly for that… She makes a mess in my bathroom and you know how I like stuff clean and organized." Jay said, kind of embarrassed.

"Yes I know Jay Halstead "The Cleaning Lady"!" Mouse added, breaking out in a big laugh making Jay laugh too until they heard the knock.

Erin was at Jay's door fluctuating between knocking or not. She was home alone and for a moment she put her life in perspective. Voight was the only man that she could call a father, but was she ready to fight the world to protect him? Did she agree with his actions? Did he even kill that guy anyway? What was she doing at home by herself? She had someone in her life now, someone that she could trust and could help her decide what to do with all that she didn't know about that night?

She could not close herself in her shell again. Jay would not forgive her this time. He was always reminding her that he was there and she could not go to down rabbit hole again.

"What are you doing girl?" She thought to herself.

"Are you expecting someone?" Mouse asked.

Jay smile to himself, he already knew who it was. "No I'm not! But it's very good that she came!"

"She? How you know who it is?" Mouse asked as Jay got up to open the door. When he saw Erin at the door, he added, smiling to himself, "Never mind…"

Jay gave her space to enter and smoothly speak to her trying to not trigger any regret on her by coming to him. "I thought you wanted to stay alone?"

She smiled at him. She noticed his insecurity, he knew her too damn well and knew how this was really thin ice for her. "I just thought that I should not fall into old habits."

Jay' face lit in big smile and he hugged her, kissing her quickly on her lips. "That was an excellent decision!"

She felt uncomfortable with the kiss, because Mouse was just right there. "Jay!" She said waving at Mouse.

"What? Is just Mouse come on…" He added but she wasn't convinced. "Hey! Mouse knows all about us ok!"

She nodded"Ok!"

Mouse looked at them. "Maybe I should go!" And picked his jacket from the back of the couch.

"No Mouse! It's ok. I came here and overran your evening… you should stay. I need some distraction for sure and I guess you could tell me some juicy stories about Jay in the army, no?"

"No!No!No! No stories about Jay!" Jay said waving his hands in disagreement and making Mouse break out laughing again.

Erin and Mouse sat on the couch leaving no room for Jay. He looked at them and felt a little relief. It was important for him that Mouse feel comfortable around Erin and vice versa. And the most important part of this evening was that Erin was at his house chit chatting with the two of them with no worries that he noticed.

Jay ended up sitting on the floor near them. "You know that I will kill you if you tell something that could embarrassed me for any reason. Don't you?" Jay said facing Mouse trying to make an upset face.

Erin laughed. "And I will pay you with a big dinner at the Fat Pig if you tell me something juicy about him."

Mouse rub his hands in discomfort.

"Erin stop with that you are making Mouse uncomfortable!"

"No she is not!" Mouse said.

"Ok but I don't want to hear about my funny stories. I already know them all."

Erin gave an understanding smile and placed a soft kiss on Jay's lips caressing his hair distractedly not noticing that she was doing it in front of Mouse. Jay noticed how comfortable she was. Yes Jay was Mouse best friend and yes they were alone in there but she was never so intimate with him in front of other people. But he was enjoying this change of behavior on her and he was not going to complain about it, but that was no reason to let Erin dig out of Mouse some shady story about how he broke his front tooth in some stupid prank and had to replace it overseas by some shady doctor with everybody making fun of him because first he looked like an old man and than the replaced tooth had a totally different color compare to the rest. Or about that time when he lost his ID and his commander ordered him to clean the bathrooms for a week.

But Mouse surprised him by telling the story of how they both end up in a detention room in some small town with two mad guards that really didn't know how do their work.

" You know Halstead is a really Dun Juan right?" Mouse asked teasing.

Jay just shook his head smiling to himself and knowing that he had lost this battle.

"So we were in some small city walking around at a small street market and a girl came after Jay to sell him some food in a basket. Jay always managed to make the girls come after him. Can't really understand why." He said smiling.

His comment made Erin smile at her man. He was for sure really handsome and she knew she was a lucky girl. With that in her mind she kept caressing his hair.

"So the girl insists he has to by some local vegetables or something. Jay argued with her that he didn't wanted nothing from her basket so she offered him herself, making Jay almost choke himself in surprise when she showed him her naked breasts." Mouse said already laughing remembering Jay's face when the girl tried to get closer to him. "He try to run from the situation, but some local police was passing by and caught Jay pushing the girl away from him. So the four of us that was there, were taken to some shady police station to be interrogate. Of course when we got there we were put in a small interrogation room and had to wait for more than an hour for someone to come and ask for our ids. And than Jay pull up his gallons and we left with some wise advise about not messing around with the locals and with a very shy Jay. As you can imagine this was motive for mocking him for months.

"So you tried to full around with the locals and ended up in jail. Very responsible of you Jay." Erin said jokingly.

"Hey it was the girl who came to me and I was just trying to get rid of her." Jay said in his defense.

They laughed at him and Mouse got up preparing to leave. "Well I'm leaving guys. It's late!"

"Already?" Jay asked.

"I'm tired and you two need your privacy. I can't imagine how your life is, working together and be profissional and all that," Mouse said smiling.

Erin smiled and squeezed Jay's shoulder.

Before he left Mouse turned back and spoke, his eyes cast to the floor. "Could you two come with me tomorrow to Molly's after shift?"

Erin and Jay looked at each other and smiled. Jay questioned Erin without talking and she nod in agreement. Jay rubbed her leg and smiling she asked. "Of course man, but why?"

Mouse still couldn't face them. "I kind of have a date!"

"And you want us to chaperon?" Jay asked laughing.

"Hey don't be like that!" Erin said taping her boyfriend's head. "Of course we will go with you Mouse, if that makes you more confident!"

"It will and it will not look like a real date, so I think it will be better." Mouse said finally facing them. "And Erin understands me better than you, you ass!" Mouse said to Jay.

"Hey! I got it, I was just messing around!" Jay said, getting up and saying goodbye to his friend.

"So... Do you want to talk about it?" Jay asked slowly when they finally were alone and comfortably arranged in the couch, with her legs on top of his lap.

"I know you are here for me and I will not shut you down, but I need time to process ok?" She asked and kissed him slowly on his mouth.

He nodded, hugging her to him. "I'm here! For all!" Once again he thought about asking her to move in with him and once again he thought that it was not a good time. He could feel how insecure she was. She asked him for time to handle Voight and he would give her time. But he needed to face her and ask her soon. She really needed him now and he really wanted to be there for her. He loved her for God sake, why was it so hard to ask her this.

It's hard because you know her and know how something like this could make her run away, you really don't want to cage her. She needs to feel safe. He thought. Soon Jay! Soon! And clearing his head from all this, he kissed her deeply and let her use his chest as pillow as she usually like to do.

Let me know what you think ;) and thank you so much for reading.
