A/N: I got lots of nice reviews for my first chapter to continue. This was my first time writing, so I'm very glad you guys enjoyed it. Here's another one shot. The one shots will be random unless stated other wise if they're 2 parts.

Hank felt guilty, but he wasn't about to admit it to Olivia. She'd push him to do the right thing. Sometimes dating an opposite from yourself is tough, but he knew she wanted his good side to show here and there. She was supposed to come this weekend.

Being a Sargent and CO was tough if you're needed during case that meant they couldn't leave. It was the con of being in control of a unit. They never made anything official 'till the day just to be safe. Their jobs were risky already and she had to deal with her son Noah. If she couldn't come he'd fly out.

Hank was in deep thought thinking if he should tell Erin about him and Olivia. He was too deep in his mind to notice that Olivia called. He went to kitchen, grabbed a beer and sat down. He looked at phone and called back Olivia.

"Hey, sorry I missed your call." Hank said.

"It's fine. Are we still good? I don't have any cases." Olivia said.

"Yeah, we're still on. What time?" Hank asked.

"Don't worry about time. I'll call when I'm leaving." Olivia responded.

"If I can't get you I'll have Alvin come and get you." Hank said.

"Alright, I gotta go. I'll call when I'm home. Stay safe." She said.

"Stay safe too." He said before hanging up.

He heard his door unlock. He quickly went for his gun and hid. He heard something roll and stop, then a few things drop. It was definitely heavy whatever dropped. Next he heard foot steps.

What took him by surprise was the voice that spoke.

"Hank if I come into that living-room and that gun is your hand I will leave." She warned.

Hank walked out putting his hands out as if he was a suspect. He was laughing, he had no idea she knew about the gun thing. Maybe Erin slipper it when he had taken SVU out to dinner last time they closed a case together.

He went to Olivia hugging her, taking in her scent. Hank let go of her for a quick kiss and grabbed her stuff bringing it to the bedroom. He need to think quick to avoid Olivia asking when he'd tell Erin. It bother her a little how before they got together he'd brag about her "being" his daughter and now he was hiding to tell Erin.

Olivia took her shoes and coat off and went upstairs to the bedroom they shared when she came, which wasn't very often as he preferred Manhattan. She stood in the doorway looking at Hank wondering why he was "afraid" to tell her.

"Hank," Olivia said.

"Dinner?" Hank questioned.

"Not hungry and if you don't tell her I will." Olivia warned.

"I meant I'll tell her over dinner tomorrow. Even if I have case." He responded looking for space to throw her bag.

"Good, now can we sleep? Who cares about the bag. Slid it under the bed, call it a day." Olivia said while undressing.

She told Hank about how she got those scars and marks. It made her feel uncomfortable, but he made her realize that it's apart of her. It only came up when Hank saw by accident. At first she would refuse then she told him while trying to close a case on a psychotic rapist he got to her. He knew she was hiding more of it, so he didn't bother her anymore about it.

Around 4 he got called to a scene. He wrote a note telling her where he was and to call if anything happens. She awoke a couple of hours later reading his note and decided to stay in. She knew where his other car was, but she didn't know Chicago well enough to leave.

Hank walked into Intelligence pissed. He wanted to catch this son-of-a-bitch as nobody was gonna get past Hank without a mark.

"Who is this guy?!" He practically screamed.

Adam scrambled for the iPad and said, "Rafael Ruíze, 25 and his wrap sheet is a mile long. Some should have kept him in jail 'till he's a senior citizen, but it seems like he knows someone from the inside."

"When you find this son-of-a-bitch throw him into the cage. Alvin and I will integrate him." Voight said before slamming his door.

After a while Lindsey came in saying her and Halstead were gonna pick up Ruíze, but Hank said send Alvin with Ruzek. She told them that and came back. Something was off with Hank, he'd yell, but this was different. Erin was gonna find out.

He looked up when he heard his door close quietly. He groaned, what could she want at a moment like this. At least now he can tell her about dinner. It was now or Olivia tells.

"Hank what's bothering you?" Lindsey asked.

"I'll tell you at dinner. Be ready by 7:30." He said

"Why can't you tell me now?" Erin questioned.

"Because we have a case in our hands and unless you want to here the commissioner yell." Hank warned.

With that Erin left Hank's office. Ruzek knocked and told him Alvin is waiting at the cage. Hank nodded and got up. One thing he hated most were dirty cops. Most say pet peeve, but no it was a hatred.

When he finally got Ruíze to snitch he started giving orders on how they were gonna arrest Officer Joan Lawmen and his partner Will Shaw. This was gonna end badly, but Voight didn't care, he was gonna give them what they deserved.

It was 6 when he sent everyone home. They can do paperwork in the morning. Before leaving Hank said he'd pick her up at her place by 7. He called Olivia asking her if she can find him a pair of shoes and apologized for not calling all day. By the time he got home she had an outfit waiting and pushed him towards the bathroom. His guess he smelled like work, he didn't fight her on it. Ten minutes tops he was out.

Before he left to pick Erin up she told him good luck. They kissed and he was out the door. In no time he picked Erin up and now they were sitting down at the table. She knew something was up and that was why he said dinner and he'll explain. He had some explaining to do then.

"Hank, you've been quiet all night. What did you want to tell me?" Erin asked.

"Erin, I may hide stuff from you, but this is something I can't hide." Hank said.

"You're scaring me now. If you killed someone just tell me." She stated.

"No, I didn't kill anyone. I'm seeing someone." He said slowly.

"Is she someone I know? When do I get to meet her?" She keep asking.

"You already know her." He said even slower from the first.

"Hank just tell me who it is." She spatted, now sounding impatient.

"Olivia Benson." He said, sounding relieved.

"No way. Is that why you leave every other month? She's here isn't she? Let's go." Erin said getting up.

Hank dropped a couple of twenties and went to the car. He drove slowly to his apartment, but the moment they reached his place she jumped out of his car. Erin banged on the door 'till Olivia opened the door. By then Hank was walking up the stairs with an apologetic look on his face. Olivia didn't know what do, so she followed Erin to the living-room and sat across from her.

"I'm guessing he told you." Olivia said.

Erin nodded her head. She didn't know what to say. Her emotions were all over the place.

"I'm not mad. Just surprised someone finally got through to him." Erin stated, after awhile of awkward silence.

"Good because if you were mad I'd kick you out the house." Hank stated.

Olivia gave him a look that said shut it. She wasn't having any of his rudeness neither was she gonna deal with it with Erin.

What surprised her was that Erin got up and hugged her and whispered, "Thanks for being there when I wasn't."

The ladies both walked to kitchen talking about what God knows. He was just happy that his girls were happy with each other and not one of them crying. If Erin and Olivia were happy he was too.

Next was announcing it to both squads.

A/N: I had a some fun writing this chapter. I hope it didn't bother any of you that I added a little case to this. If I get some reviews to continue next chapter should be them both telling their squad. I know for SVU some secrets stay hidden, but I feel like this shouldn't because of an episode I watched. I felt like it was important Hank & Olivia told Erin as she has been part of his life for years. Hope you enjoyed the second one shot!
