A/N: Just a cool side note. I titled this story ONE because of the characters' names (Olivia Noah Elliot). After I started writing, I came across a song by Ed Sheeran called One and was blown away by the similarity between the lyrics of the song and Olivia and Elliot's situation. It's a beautiful song! Check it out! Also, thank you all for reading, favoriting and reviewing! It means a lot. Enjoy!

Spoilers: Post ep. P.C Season 11 Episode 13.

They sat there discussing how tomorrow would go. Elliot wondered if he'd get his old desk back too, or if it was currently occupied by someone else. If he was being honest with himself, he only wanted his old desk back if his partner would be sitting right across from him again. He didn't care either way. All he cared about was having Olivia back as his partner.

"So are we in the middle of any cases?" He asked.

"Yes. Two actually. Well . . . one and a half."

"One and a half?"

"Yeah, we have one, and Fin and Carisi were sharing one with Nick and I. So now, you and I have one and a half." She explained.

"Got ya." He said understanding now.

"Actually, I should probably brief you on them real quick. You got a second?" She went to grab the case files.

"Yeah. Yeah of course, but hey Liv? What do you say we get out of here, grab something to eat and then go over the cases?"

She stopped what she was doing and looked back at him. "Yeah. Okay."

He smiled then. His internal excitement too overwhelming to ignore. "I'll drive." He volunteered as he grabbed her coat and held it open for her.

She sat the files down as she turned her back to Elliot and let him help her into her coat.

"Thanks." She turned and gave him a small smile as she buttoned up her coat.

"No problem." He smiled back at her. "You ready?"

She grabbed the files and turned off her desk light. "Yep."

She followed him out to his car and he held the passenger side door open for her.

She thanked him and climbed in. Her stomach was fluttering again. It had been so long since they last did this.

Elliot jumped into the driver seat and started the car. He blew into his hands and rubbed them together. "So, Chinese takeout?" He asked.

"Uh, sure, but where are we 'taking out' to?" She questioned.

"I know a place." He smiled at her and called the Chinese restaurant.

After they picked up their Chinese, Elliot pulled the car up to a tall building and put it in park.

"Alright. We're here." He announced.

Olivia looked around through all of the car windows. "Elliot, where exactly are we again?"

"My new apartment."

"Your new apartment?" She was utterly confused now.

"Yep." He got out of the car and walked around to her side to open the door for her.

"You sold your house?"

"Not quite. I didn't sell the house. Kathy's still living there. We got divorced last year." He shut the door after she climbed out.

She spun around at his words and stared at him with mouth agape.

"What?" He half laughed. He knew what was about to come. "Here, hand me the Chinese."

"Why didn't you tell me this back at the precinct?!" She asked in shock and disbelief. Her tone was almost exasperated.

"Because you would have asked me a hundred questions and we would have never made it out of there. Now you have all the time in the world to ask me whatever you want. Well, at least until work tomorrow morning."

He started walking towards the front door of the building.

"Have you been living here for a year?" She followed behind him.

"No. I just finished moving in on Saturday. Kathy and I have been divorced for a year, but we still lived together until I could find and afford a place of my own. I started moving in about a month ago."

They were in the elevator now and Elliot pressed the button that took them to the third floor.

"So when did you plan to tell me about you and Kathy?"

"Right when I did. I knew you weren't going to walk into my new apartment with no questions."

'Touché' she thought to herself.

"This is me. Room 314." He stated as he pulled out his key.

He opened the door, flipped on the lights, and held it open for Olivia to enter.

She looked around for a moment. Everything was so neat and tidy, and it all looked brand new! She looked back at him then.

"I'm sorry, El." Her eyes met his. "Are you okay? With all this, I mean?"

"I'm more than okay, Liv."

"Really?" She questioned with skepticism.

"Really." He assured her. "I promise."

She gave a sigh of relief.

"Now come on, let's eat." He tilted his head to gesture towards the kitchen.

They ate their Chinese and made it back into the living room where they found themselves on the couch laughing and catching up. They had completely forgot all about going over the cases.

"No way, El! Babs was way more into you! Do we have to call Munch to settle this bet?" She hadn't laughed this hard in years.

"What are you talking about?! She completely despised me for 90% of the case! She hit on you and she tried to kiss you! She wanted you more. No competition."

"Yeah, tried to kiss me! She successfully kissed you! Explain your way out of that one!"

"It was a surprise attack! I wouldn't have let her if I would have seen it coming! And you just stood there with a smug grin on your face. Come to think of it, I bet you put her up to it! She wanted you, but you convinced her to pull a move on me!" He was grinning away. He knew this would rile her up.

Her mouth dropped open in complete disbelief. "I did no such thing!"

"Oh yeah, right!" He started when her phone began to ring.

She picked it up, "Benson."

She gasped. "Oh my gosh, Noah! I am so sorry, Lucy! Something came up at work and I completely lost track of time! I'll be right there!" She hung up and ran her hands through her hair in a stressful manner.

"What's wrong?" Elliot asked with a confused look.

"I completely forgot about Noah." She stood up and dashed for her coat.

"Who's Noah?" Elliot, without a doubt, had a jealous undertone in his voice.

"He's my baby." She answered slipping on her coat.

"You have a baby?!" Now it was his turn to be shocked.

"Yes." She finished buttoning up her coat and reached for the door. "Thank you for everything, Elliot. I'll see you tomorrow."

He caught her elbow then and spun her around. "Who did you have a baby with?" His eyes were narrowed on hers and his tone was so serious. It sent a shiver right through her.

"Elliot, I don't have time to play 20 questions! I need to get home to relieve my babysitter!"

"Well then I'll take you home."

"No, El, it's late and you have work in the morning."

"Liv, I drove you here. Your car's at the precinct. Just let me take you home."

"Crap! How am I getting to work tomorrow?" She was so angry at herself for being so irresponsible.

"I'll pick you up in the morning." He offered.

"Are you sure? I hate to do that to you." She gave him an apologetic look.

"Liv, I am absolutely sure. It'd be my pleasure to carpool with you on my first day back." He was smiling at her again.

"El, I can't thank you enough."

"Hey, what are partners for?" He was still smiling at her and gently rubbing her arm. "Come on. Let's get you home."
