Chapter 1

"Is that…is that Ruzek?" Erin Lindsey asked.

Kim turned around on her bar stool. She saw Adam coming through the door at Molly's. She couldn't help but let out a small gasp. It had been months since she had last seen him. Months since he had basically vanished to work a case undercover for another department. Kim didn't even know he was going. Nobody seemed to know. It was as if he had disappeared without telling a soul. It had been weird not having him around when she had gotten so used to it. Even when they weren't together, Kim liked knowing he was there.

"Yeah," Kim whispered in response to Erin's question.

Kim couldn't deny the primal urges she got whenever she saw Adam. He brought something out in her that no other man ever had. Whenever she saw him, she wanted to physically touch him. And it wasn't always sexual either. Sometimes just holding his hand or having him brush his hand across her cheek was enough to satisfy her. Even when they were no longer together, she still felt that way towards him. She had missed that feeling when he was gone.

Adam walked right up to the bar at Molly's and sat down. A few of the firefighters said hello to him. It had been a while since anyone had seen him and there was a lot of catching up to do. Kim couldn't help but be a little jealous that he hadn't gone up to her first to say hello. Then again, it wasn't as if he noticed her sitting in the corner. Kim wasn't sure if she should make the first move and say hello to him first.

"Is it me or is he looking hot?" Erin wondered out loud, breaking Kim's concentration.

Kim turned back around to look at Erin. Erin had a sly smile on her face. Erin was teasing her and Kim knew it.

"I'm just glad he's ok," Kim replied.

"So you were worried about him."

"He's my friend."

"Friend, huh?"

"Yes, friend," Kim clarified.

"You should go talk to him. After all, you are friends."
Kim rolled her eyes. "Shut up."
Just as Kim turned back to see what Adam was doing, she noticed he was staring directly at her. He smiled when they locked eyes. She smiled back. With a beer in his hand, Adam slid off his bar stool and walked over to the corner where Erin and Kim sat.

"Hey," he said.
"Hey yourself," Kim replied. She felt nervous, like a teenager on a first date. "Long time no see."

"Yeah."

They simply stared at each other, taking in each other's appearance as if they had been separated for years, not just months.

"Good to see you, Ruzek," Erin said.

"Yeah, you too Lindsey."
Adam didn't even look in Erin's direction when he spoke. He only had eyes for Kim.

Erin finished off her beer. "I…ah…I'm gonna go."

"No, you don't have to," Kim said, knowing that Erin was just leaving to give her and Adam alone time. As much as Kim was tempted by the idea of being alone with Adam, it scared her.

"I told Jay I wouldn't be out too late," Erin told her. "Have a good night. I'll see you tomorrow."

Erin threw some money on the table to pay for her drink and then walked off before Kim could stop her.

"Mind if I sit?" Adam asked.

"No, go ahead."

Adam sat down on the stool Erin had previously occupied.

"You look amazing," he complimented.

"Thanks, you do too. So…you're back?"

"Yeah. I finished the undercover job this morning."

"Did you get what you needed to make an arrest?"

"Yup," Adam answered. "We took down a big drug and weapons ring. It was…intense, but it was worth it."
"That's good."

"How has Intelligence been?"

"It's good," Kim answered simply.

"I heard there's a new guy. He any good?"

"He's alright." She paused. "But he's not you."
Adam smiled. "Nobody else is. So, do you ever miss being out on the streets?"
Kim shrugged. "Sometimes. But I like being in Intelligence. It…challenges me."
"Who did Voight partner you up with?"

"Olinsky," she replied.

"Really? How's that going?"

"It was rocky at first, but I think we're starting to understand each other better."
"That's good. He can be a tough nut to crack."
"Yeah, but I'm working on it."
They fell into silence. Kim couldn't believe how awkward it was to talk to him when it had always been so easy from the first day they met.

"Look…" Adam began.

"I don't…" Kim said at the same time.

"Sorry, you go first,"

"No, you go," Kim insisted.

"I was just going to say that I'm sorry that things have gotten so weird between us. I never wanted that to happen."

"It has been strange," Kim admitted. "One day you were there and the next you were just gone."

"I know."

"Was it because of me?"

Adam shrugged. "It was a lot of things."

"So what happens now?"
Adam looked at her empty beer bottle. "I buy you another beer."

Kim knew she should cut herself off. She had only had the one beer, but in the presence of Adam, one was enough. She needed to keep her head on straight and remember why she had ended things with him in the first place. But looking directly at him and feeling that familiar tug at her heart overruled her brain.

"Ok," she agreed.

3 hours later

Kim finished off her fourth beer. She felt more than a little buzz, but wasn't quite drunk. She and Adam had been talking in the corner of Molly's bar for hours. They talked about everything from what was going on in Intelligence to Adam's undercover work to stories from their childhoods. It felt like old times.

"Last call," one of the firefighters behind the bar called out.

Adam looked around. Aside from a couple of guys sitting at the bar, Kim and Adam were the only two left.

"Looks like we closed down the place," Adam said.

Kim glanced down at the time on her cell phone. "I can't believe how late it is. I should go."

"Yeah. I'll help you get a cab."

Adam reached into his pocket for his wallet. He put enough cash on the table to pay for both of their drinks.

"You don't have to pay for me," Kim said.

"You can get the next round."

"Ok," she agreed. She was happy to think of their being a 'next round.'

They said goodbye to the firefighters who were left at the bar and walked out. Kim busied herself on her phone.

"Am I really that uninteresting?" Adam joked.

"I'm looking for an uber."

"Right. I forgot, taxis are a thing of the past."

Kim found a driver within range.

"You don't have to wait with me. I'll be fine."
"I'll stick around. After all, who knows who this uber guy is."
"Now you sound like my mother," Kim said. "And in case you forgot, I am a cop. I think I can handle myself."

"I'll still wait."
They both stood in silence, neither of them knowing quite what to say. A few minutes later, a car pulled up.

"Thank you," Kim said. "I had fun tonight."

"Yeah, me too."
"I…ah…I missed this. I missed having you in my life."

"Me too," he agreed, stepping closer to her.

"Ok, well, goodnight."

"Goodnight."

Kim leaned into to hug him, but Adam turned his head so their faces were only inches apart. She knew what was about to happen and she welcomed it. He closed the gap, brushing his lips against hers. It felt familiar. It felt right. Their kiss deepened, both of them wrapping their arms around each other.

"Come home with me," Kim whispered as they parted.

"I thought you'd never ask."

Adam opened the door to the back seat of the uber car. Kim climbed in. He slid in beside her. Adam gave the driver Kim's address. He put his hand on her knee, desperately needing to be connected to her just as she needed and wanted that physical contact with him.

It took only ten minutes for the uber driver to get them home, but it felt like an eternity. Adam threw a twenty dollar bill at the driver, not waiting to get his change. He and Kim scrambled out of the car. They had their lips on each other before they even closed the door to the car. Somehow they managed to make their way into Kim's apartment. Even more miraculously, she was able to get her key from her pocket and she unlocked the door. By the time they made it to Kim's bedroom, they were both stripped down to their underwear, their clothes strewn on the floor of the living room and hallway. They fell onto the bed in each other's arms.

Author's Note: Without giving too much of this story away, I'll just say that I've had this idea for a while now, but was recently inspired to write it down. This is my version of how I would like to see Ruzek come back. (I did alter the kiss from last night's episode to fit my story line better) This will be a short multi-chapter story (maybe 5 or 6 chapters). Hope you liked it so far. Don't forget to review!
