A/N: Decided to write a one-shot for Father's Day. Enjoy! As always, I don't own any of the characters.

Father's Day

Father's Day for Hank last year had been low key because of Justin's death but so much had changed in the last year. He and Olivia officially got together shortly after Justin's death and had recently gotten married. He also officially adopted Noah. Olivia and Noah moved to Chicago after she retired and Erin had moved to New York for her new job. Olivia wanted to surprise her husband for Father's Day this year. She wanted to try to have the entire family together for a change. Olive was all for it, so she and Daniel were going to spend the entire weekend with them. Erin was going to try but she couldn't promise anything. Olivia told Olive she would pick them up at the airport. When she and Noah arrived, Olive and Daniel were already outside.

"Hey."

"Hey, Olivia."

"Hi, sweet boy."

"Hi."

"How was your flight?"

"Pretty good."

Olivia helped put the bags in the back, while Olive put Daniel in his seat.

"Hey, Noah."

"Hi."

"Noah!"

"Daniel!"

Olivia and Olive got in and then Olivia drove to the District. On the way, the boys had fallen asleep. When they arrived, she parked and then they got the boys out before heading inside.

"Hey, Trudy."

"Hey."

"Is he here?"

"He is but he's in a meeting with someone. His lawyer I think."

"Lawyer?"

"I'm sure he wouldn't mind if you went up."

"Thanks."

They went up and Trudy buzzed them in. Olivia couldn't help but wonder why Hank was talking to his lawyer. Hank had just walked out of his office when they got upstairs.

"Hank, I will get that drawn up for you as soon as possible."

"Thanks. I appreciate it."

Hank's lawyer left and then Hank pulled Olivia into his arms and kissed her.

"What did you do?"

"Why do I always have to do something?"

"Why was your lawyer here and what is he drawing up for you as soon as possible? Hank Voight, are you filing for a divorce?"

"No! Why the hell would you think that? He's redoing my Will. I'm still trying to get all the paperwork taken care of to add you and Noah to my insurance and all that other crap."

"Oh."

"I'm not filing for a divorce. We haven't been married all that long and I happen to be madly in love with you. You helped me to cope with losing Justin and you gave up everything in New York for me."

"I wanted to. I was spending more time here anyway and I didn't necessarily have the best breakup with Tucker as you know, since he kept saying that I was sleeping with you the entire time he and I were together. I still don't know what I was thinking when I started seeing him. You are clearly the one that makes me happy. You and I had had casual sex several times and I did feel more of a connection with you than I did with whatever it was that Tucker and I were doing. He never satisfied me the way you do. I don't regret ending things with him. I wanted what you and I had to be more and I'm glad you decided you did too. On several occasions, I wanted to come up with an excuse just to come here to see you. Noah was kind of confused about everything. He liked Ed but I sensed that Ed's lack of experience with children was putting a strain on their relationship. Ed had to try too hard with him. You've had a family and knew how to deal with him. You both took to each other from the moment you met."

"He's a good kid and you have done an amazing job with him."

"Thanks. That means a lot. It hasn't been easy. Being a single parent isn't easy."

"Tell me about it."

"I agree."

"Justin was 17 going on 18 when Camille died. He didn't handle her death very well but of course, neither did I. He just kept getting himself into more and more trouble even after he was released from prison. I took him to the Army Recruiting office and told him I'd see him in 4 years. A combination of the Army discipline and becoming a father helped him grow up quite a bit. I was really proud of him and I know I didn't tell him that enough."

"He knew. When I told him I was pregnant, he said he wanted to make you proud of him. He knew that you wanted us to be married before the baby was born and that was why you had given him Camille's engagement ring."

"She wanted him to have it. Before she died, she took it off, gave it to me and said she wanted Justin to give it to his future wife someday. She also told me that she didn't want me to spend the rest of my life alone and miserable. Just promise me that no matter what happens, I will always be a part of Daniel's life."

"You will. You are his only connection to his daddy. You've been more of a father to me than my own father ever was and I want you to be in his life. Both of you. Olivia, you're his grandma now."

"I don't have a problem with that. I just wish I had met Justin."

"I wish you had too."

Hank kissed Olivia and then the 5 of them left to head to the house. When they arrived, Hank carried the bags in and took them upstairs. The boys had woken up and wanted to play in the little pool. Olivia and Olive changed them into their swimsuits. Hank put his on as well and went to fill the pool up. He kept spraying the boys with the hose. Olivia and Olive changed and came outside as well.

"Daddy, spray Mommy!"

"Spray Gama, Papa."

"Don't even think about it!"

Hank sprayed it at her feet.

Olivia tried grabbing the hose from Hank but then he put the hose down her swimsuit and sprayed her.

"You ass!"

She got the hose away from him and did the same to him. Then she sprayed his face. They boys were laughing. The boys sprayed Olive a few time as well, so they all got into the fun before the boys played in the pool and everyone else relaxed in the sun. They all decided to go out for dinner and then came home and put the boys to bed. Erin had texted Olivia to tell her she was coming and she had an early flight.

The next morning, Olive got up with the boys and fixed breakfast for everyone. Before Hank and Olivia had gotten up, the doorbell rang. Olive went to answer it.

"Hey, Erin!"

"Hey!"

Erin hugged Olive and then they went back into the kitchen.

"Erin!"

"Hey, Noah!"

"Auntie!"

"Hey, you!"

Erin hugged the boys and then Hank and Olivia got up and came downstairs.

"Hey, kiddo!"

"Hey!"

Erin hugged Hank and Olivia and then everyone had breakfast. Erin got the boys dressed, while everyone else took their showers. They decided to spend the day at Brookfield Zoo and decided to take the train. They got to Union Station, got the tickets and waited for the train. They boarded the train and then they took it to the Hollywood Stop to walk a short distance to the Zoo. They saw as much as they could and took lots of pictures of the boys. They left and walked back to the train station to wait for the train to go back downtown. The stopped for dinner on the way home. Once they got home, they relaxed in the living room.

"Did you guys have fun?"

"Yeah!"

"Good. How about you, Babe?"

"Yeah, I did."

"I did too."

"Me too."

"So did I. Erin, are you planning to see anyone else while you're here?"

"I don't even want to see Jay. I may text Kim and see if she wants to get together later."

"You're going to have to deal with Halstead sooner or later."

"I'm not ready to."

"He'd probably kill me if I told you this but after you left, he told me he wanted to ask you to marry him."

"I probably would have turned him down."

"Is everything going ok in New York?"

"Oh, yeah. At least I know people there. I hang out with Fin, Amanda and Carisi a lot. Amanda said she's thinking about bringing Jesse out one of these weekends. Lucy said to say hi to everyone and she misses her little buddy Noah so much."

"I don't doubt that. Tell her we said hi back and tell the rest of them, including Barba, that we said hi too."

"I will. Barba misses you a lot. He'd rather go at it with you than Fin any day of the week. Thanks for letting me take over your apartment. That saved me a lot of time having to look for one I could afford."

"No problem. I believe it about Barba. How's the job going?"

"Pretty good."

"That's great. You know, you said you'd turn Jay down if he proposed. He inquired about transferring to SVU. I told him to call Fin or Chief Dodds. He's really serious about this. He talked to both Hank and I about this too."

"I still don't know. He wasn't honest with me about being married while we were together. How do I know he's finally rid of her? I don't. I wanted to start my life over in New York and I really don't want to be in a long distance relationship."

"He's willing to relocate though."

"I know."

"Maybe you should at least talk to him."

"I'll see."

Erin texted Kim to see if she wanted to get together. She said she did, so Erin left and met Kim at Molly's. Olivia took the boys up and gave them a bath before getting them ready for bed. Olive went upstairs to help get the boys settled, while Hank went up to the bedroom to put the TV on. After the boys were in bed, Olivia joined Hank in the bedroom and locked the door, while Olive went into her room to read.

"Hey there, sexy!"

"Hey, yourself."

They started kissing, they undressed each other and then they made love. Afterwards they were wrapped in each other's arms.

"I love you."

"I love you too. Are you going to tell me what we are doing tomorrow?"

"We are going to Navy Pier and going on the Seadog for the Lake and River Architectural Tour. Then we will probably have lunch there as well. Noah told me you'd like that. The boys will probably spend some time at the Children's Museum while we're there. "

"He's right but really, all I care about is spending the day with my family. We could spend the day here doing nothing as long as I'm with the people I love the most."

"I just wanted this weekend to be special for you after how hard last Father's Day was. Noah is just glad he now has a daddy. You at least want to spend time with him."

"I love him as much as I loved Justin. I wanted to be his daddy as much as I wanted to be your husband."

"Well, I definitely wanted to be your wife and now I am so glad I am."

"I am too."

"Are you going to be ok if Jay goes to New York?"

"We'll manage. At least Antonio is back with us. I don't think Jay is going to give up on her that easily but the decision is ultimately hers."

"It sure is."

Hank and Olivia started kissing and made love again before falling asleep in each other's arms. A little while later, Olive went to bed as well. Erin met Kim and ended up running into the rest of the squad and most of the firefighters at Molly's. She and Jay talked but she told him that she needed time to think about things and she's trying to start over, so not to make any decisions about transferring to New York just yet. While it was not the answer he wanted to hear, he accepted it for the time being. Erin went back to the house, got ready for bed, got settled on the sofa and cried herself to sleep.

The next morning, Olivia, Erin, Olive and the boys got up before Hank did and fixed breakfast. Olivia told the boys to go wake Hank up when they were ready, so they went up and jumped on the bed to wake him up.

"Happy Father's Day, Daddy!"

"Happy Papa's Day, Papa!"

"Thank you."

"We made you breakfast."

"You did, huh?"

"Yeah!"

Olivia, Erin and Olive came up.

"Happy Father's Day, Honey!"

"Thanks, Babe."

"Happy Father's Day, Hank!"

"Thanks, Olive."

"Happy Father's Day, old man!"

"Old man? Love you too, Erin."

Erin kissed Hank's cheek.

"Ok, you two, let's go eat."

"Ok."

Erin and Olive took the boys downstairs, while Olivia stayed with Hank. They ate breakfast and then everyone got ready. Once everyone was ready, they went to Navy Pier. They went on the Seadog and then they had lunch. After lunch, they went on the Ferris wheel , took the boys to the Children's Museum and then they looked in some of the shops before they left. They went home and then once they were ready to go, Erin, Olive and Daniel left for the airport after they said goodbye to Hank, Olivia and Noah.

"Did you have fun?"

"I did. Thank you."

"You're welcome."

"Do you want to cook out tonight?"

"Absolutely."

Hank went to start the grill and they cooked out hot dogs for dinner. They ate out on the patio, made s'mores and sat outside until it was time to put Noah to bed. For Hank, this had been one of the most memorable Father's Days he had celebrated in a while. Now that he had his new son, he knew he'd have more of a reason to celebrate.
