A/N: This is the third part for the last couple chapters and I wasn't planning to write this one but I am anyway. I should be trying to update "Townhouse Incident – The Crossover" and "I'm Here For You" but ideas for this one keep popping into my head instead. I do like suggestions too, so if you have any, please leave me a review or send me a PM. I don't own any of the characters except my own.

Happy

As soon as Hank returned to Chicago, he bought Olivia an engagement ring and a few weeks later, she brought Noah to Chicago. Hank proposed to her then and she of course said yes. Hank retired and moved to New York to be with Olivia and Noah. They bought a townhouse to have more room for the 3 of them. Trevor and Erin became closer and Erin found out that she was pregnant. Trevor ended up proposing to her and she said yes. Hank loved that Erin was so happy and finally having the family she has always wanted. With Olive, Daniel, most of the squad from Intelligence, Olivia's squad, Cragen, Munch, Melinda, Barba and Trevor's parents, Jim and Vivian, supporting them, Hank and Olivia and Trevor and Erin got married at the Courthouse. Hank officially adopted Noah and Erin officially adopted Charlie. Trevor's mother had grown to love Erin even after Erin had told her everything about her past. Vivian knew Erin made her son and grandson so happy and she was also looking forward to her granddaughter's birth. Erin and Trevor found out they were having a girl and decided to name her Isabella Grace but she would be known as Bella. Hank and Olivia had become close to Trevor's parents and because Erin was closer to Olivia than she was to Bunny, so both sets of grandparents were excited about Bella's arrival.

Erin was at the end of her pregnancy and already off of work. They had the nanny for Charlie but Erin spent a lot of time with Hank, Noah and Lucy. Tracy, Charlie's nanny, had asked for the day off as did Lucy, so Hank and Erin picked the boys up from their respective Preschools and decided to go see Olivia for lunch. Trevor was supposed to be in court all day. They arrived at the Precinct and Olivia and her squad were busy with a case and they were both surprised to see some of the group from Chicago.

"Hey, Babe."

"Hey, Honey. I know we had talked about going out to lunch today but we got slammed with this case. I'm sorry. I should have called."

"It's ok."

"Hey, Sarge."

"Hey, Atwater."

"Hey, Erin."

"Kevin."

Kim, Adam and Jay came in.

"Erin, you look gorgeous."

"Thanks, Kim."

"Hey, Sarge."

"Hey, you two."

"Erin, guess what?"

"What?"

"Adam and I are back together."

"Hey, that's great. Jay."

"Erin."

Erin started rubbing her belly.

"Erin sweetie, go sit in my office."

"Thanks."

Erin went into Olivia's office and sat on the sofa to rest. Jay kept staring at her even after she went into the office.

"You had your chance with her, Halstead."

"Maybe if you hadn't sent her here to get her away from me, she would be carrying my baby right now."

"Guys, go in with Erin please."

"Ok."

"Shut the door."

Noah and Charlie went into Olivia's office and shut the door.

"I don't like you blaming me for your relationship with Erin ending. You brought that on yourself when you neglected to tell her that you were married and not officially divorced while you were with her."

"If you haven't noticed, you're not her father."

"I am well aware of that but she is the closest I will ever have to having a daughter. For your information, I was told by Chief Lugo that either I do something about Erin or he'd shut down Intelligence completely. I have connections with someone in the FBI and inquired about a job for Erin. She contacted her to make the offer and Erin accepted it. Erin is a big girl and very capable of making her own decisions. This is the happiest I have seen her in a very long time. Don't ruin it for her."

"So, then as usual, you did this to benefit yourself."

"I did this for the rest of the Unit. I didn't want to but I had to. My next choice was to send her to Olivia but since she was being placed on administrative leave, I wasn't sure having her go to SVU was a good idea, since I know how much Olivia likes things done by the book."

"I would have taken her. You know that. Even though what she did was wrong."

"She knows that and she respects you."

Noah came running out of Olivia's office.

"Mommy, Erin peed all over your sofa."

"What?"

"It's all wet."

"Her water broke."

"What's that mean?"

"It means she's in labor. The baby is coming."

"Oh. CHARLIE, THE BABY IS COMING."

"I DON'T SEE THE BABY YET."

"Oh, good grief!"

Hank went to get Erin and Charlie but by then, Trevor had come in.

"Oh, thank goodness you're here!"

"What's wrong?"

"Erin is in labor. Her water already broke."

Trevor went into Olivia's office.

"Babe, are you ok?"

"I am now that you're here. I love you so much."

"I love you too."

Trevor kissed Erin and then they headed to the hospital.

"Liv, go be with your family. We got this."

"Thanks, Fin. Call if you need me."

"Yeah, I will."

Hank and Olivia left with the boys and headed to the hospital. On the way, Olivia texted Trevor's parents and Olive to tell them the baby was coming. Olive and Daniel were already on their way to New York. As soon as Vivian and Jim got Olivia's text, they headed to Manhattan from The Hamptons. When Olive and Daniel's plane landed, she got Olivia's message and replied saying they were there and needed someone pick them up.

"Olive and Daniel are in New York at LaGuardia. She needs someone to pick them up."

"You can go. These two are out and I don't want to bother them."

"Ok."

Olivia kissed Hank and then she headed to the airport. It was later than she thought, so traffic was pretty bad. When she finally got through the traffic and arrived at the airport, Olive and Daniel were waiting for her. Olivia got out and helped with the bags, while Olive put Daniel in. They got in and headed to the hospital.

"I am so sorry."

"It's ok. I just have bad timing. How's Erin?"

"She's hanging in there."

"Good. How did you get the job of picking us up?"

"Noah and Charlie were sleeping on Hank and he didn't want to bother them. We had another case that started with Intelligence and Jay is sulking and thinks Hank is the reason his relationship with Erin ended."

"Isn't Erin an adult?"

"That's exactly what Hank said."

"Trevor is so sweet and Charlie is as adorable as Noah. Erin seems a lot happier now."

"She really is. A lot of it too was because she was missing Hank like crazy, so she's really glad he's here and able to share this special moment with her."

"Who else is here from Chicago?"

"Kevin, Kim and Adam."

The traffic heading back was just as slow as it was getting there. When they got there, Hank was waiting outside for them.

"Took you long enough."

"There is such a thing as traffic. This isn't Chicago, you know."

"So I've noticed. I'll take Chicago over this nut house any day."

"What are you saying?"

"I'm saying I miss Chicago but I chose you."

"You better. Where are the boys?"

"Jim and Vivian took them for dinner after they stopped in to say hi to Erin and Trevor. Hey, Olive."

"Hey, Hank."

"Papa!"

"Hey, Daniel! I've missed you."

"Missed you too. Gramma too."

"I can't believe he's going to be 3 pretty soon."

"I know. Time flies."

"How are things going with you?"

"I guess ok. I have something I need to tell you."

"Ok."

"I joined this single parents' group and I have sort of been seeing this single dad I met. I know it hasn't been 2 years yet but I'm starting to get a little lonely. I wasn't sure how to tell you."

"I'm fine with it. You should have brought him with you."

"Not yet. Maybe this summer we'll come out here. It's complicated because he has his late wife's parents to deal with and I still have you . If anything happens between us, Daniel will always be a part of your life. Scott is from this area actually. His daughter, Melissa is just a little older than Daniel."

"How's Daniel with him?"

"He seems to like him and she seems to like me."

Olive saw a car pull up and saw who got out.

"Scott, what are you doing here?"

"I left right after you did. I decided to come out here to see my brother. I have a sister-in-law I haven't met yet. I texted him and he said she was in labor. Apparently I get to meet my sister-in-law and niece on the same day."

"Your last name wouldn't be Langan, would it?"

"It is. You must be Hank and Olivia. It's so nice to finally meet you. I'm guessing my big bother has never mentioned me. I'm not surprised."

"He said he had several siblings."

"I didn't put two and two together when we started hanging out and you told me your last name was Langan."

"How many of you are there?"

"There are 4 of us. Trevor is the oldest, then Maggie, then Jenna and then me. I'm 17 years younger than Trevor. This is Melissa."

"Hi Melissa."

"Hi."

"Do you ladies want to grab something to eat?"

"I do but I need to check in with Fin first."

"Sure. I'm hungry and he probably is too."

"Scott, would you and your daughter like to join us?"

"Yeah, sure. Let me go say hi to my bro first."

"I'll go with you. I want to check on Erin."

Olivia checked in with Fin, while everyone else went to see Erin.

"Hey, Trev."

"Scotty, how are you?"

"I'm good. Congratulations."

"Thanks. This is my wife, Erin. Erin, this is my brother, Scott and my niece, Melissa."

"It's nice to meet you, Erin."

"You too."

"How are you doin', kid?"

"I want it over with. Where are Liv and the boys?"

"Olivia is checking in with Fin and the boys are with Trevor's parents out to dinner somewhere."

"Oh. Hey, Olive."

"Hey, Erin."

"So, it turns out that Olive and Scott are sort of seeing each other."

"What? Olive, that's great!"

"Thanks. Maybe it won't be so awkward if things start to get serious between us since you're married to Trevor, so then I'll have someone I know."

Erin started having another contraction and then Olivia came in.

"The case ended with the suspect killing himself. Kevin, Kim and Adam are coming here and Jay is heading back to Chicago feeling sorry for himself."

"Good. I don't care if I ever see him again."

"He said you leaving is my fault."

"I'm a big girl. Coming to New York was the best thing I could have done. If I hadn't, I may not have met and fallen in love with Trevor and Charlie."

"We're going to go grab dinner. Trevor, call if something happens."

"I will."

Hank kissed the top of Erin's head and then they headed out to grab something for dinner. Kevin, Kim and Adam arrived and went up to the waiting room after they stopped in to see Erin. Vivian and Jim arrived back with the boys. Noah saw the 3 in the waiting room.

"Hi."

"Hey, Noah."

"Where are Mommy and Daddy?"

"They went out for dinner."

"Oh."

"Is my sister here yet?"

"Not yet."

"I'm going to go check on things. Charlie, stay with Grandpa, ok?"

"Ok, Grammy."

Vivian went to check on Erin, while Jim sat down with the boys. Fin, Amanda and Carisi came in.

"Anything?"

"Not yet."

"Where's Liv?"

"They went out to eat. We haven't seen them at all since we've been here."

Vivian came back.

"They are taking her to the delivery room right now."

Vivian texted Olivia and told her. Olivia texted back and said they'd be back as soon as they could. Olivia, Hank, Olive, Daniel, Scott and Melissa arrived back at the hospital.

"Did we make it before the baby?"

"Yep. I haven't seen Trevor. Hello, Scott."

"Hey, Mom, Dad."

Scott hugged both of his parents. Olivia and Hank sat down and Noah crawled up on Olivia's lap.

"Missy, say hi to Grandma and Grandpa."

"Hi."

"Hi, Sweetie."

Vivian picked Melissa up and held her.

"How's Grandma's girl?"

"Good. Love you, Papa."

"I love you too, Pumpkin."

"How was dinner?"

"It was fine."

"This is Olive, our daughter-in-law and our grandson, Daniel. She and Scott know each other."

"These are my parents, Jim and Vivian."

"It's nice to meet you, Olive."

"You too."

A little while later, Bella was born and as soon as she was cleaned up, weighed and measured and Erin got to hold her, Trevor bought her out to meet everyone.

"Look who I found."

"Oh, Trevor, she's beautiful."

"Thank you. She is 9 pounds, 6 ounces and 21 inches long."

"She's a Langan alright!"

"Very funny."

"Is that my sister?"

"It sure is, Buddy."

"Can I hold her, Sweetie?"

"Of course, Mom."

Scott took Melissa and then Trevor handed Bella to Vivian.

"You are a beautiful little girl."

"Congratulations, Trevor."

"Thanks."

"Congratulations, Man."

"Thanks."

"How's Erin?"

"She's great. I don't want to keep her from Erin for very long."

"Can I take a picture, so I can send it to the rest of our squad?"

"Yeah, sure."

Kim took a picture and then Trevor took Bella back to Erin, who was already back in her room.

"There's your mama."

"Hi baby girl."

Trevor handed Bella to Erin. Hank had wandered off and ended up in Erin's room.

"Hey, kid."

"Hey."

"She's real beautiful."

"Thanks. Would you like to hold her?"

"You don't even have to ask."

Hank took Bella and sat down.

"Hi there."

Then Olivia came in.

"Somehow I knew I'd find you here."

"Guilty."

Olivia kissed Hank and then she kissed the top of Bella's head. Hank then handed her to Olivia, so she could hold her for a little bit. Olivia gave her back to Erin and then she started fussing, so Erin fed her for the first time. Everyone else came to see them before they headed home or to their hotels. Jim and Vivian took Charlie home, so he could sleep in his own bed. That left Trevor alone with his girls for the night. A couple days later, Erin and Bella were released and went home. Charlie got to hold his baby sister for the first time.
