"So we really need to find this Doug guy. Let's work on getting as much information as possible on him when we go back tomorrow," Elliot said as he drove up to Olivia's apartment.

"Mhm," Olivia replied.

"You okay, Liv?" Elliot asked.

"Fantastic." She got out of the car and shut the door as she walked away.

Elliot turned the car off and followed. "You've hardly said a word since we left the Swing Set," he whispered, so as not to be heard by anyone they passed.

Olivia continued to open the door to her complex and headed to her apartment.

"I'm fine, Elliot. I'll see you tomorrow." She opened her door and tried to shut it, but Elliot stopped it from slamming.

"Did something happen while I was in the Playroom? Did I miss something?" he asked.

Olivia let out a frustrated laugh. "I'm the one that missed something," she muttered.

Elliot frowned and moved in closer, closing the door behind him. "Liv, nothing happened with Cassandra tonight, but that's not to say something won't happen the more we infiltrate… you know we might have to—"

"That's not what I'm talking about, Elliot!"

"Then what are you talking about?"

She let out a harsh sigh. "That was one hell of a story you told tonight."

Elliot's shoulders dropped and his eyes rolled. "That?" he asked innocently. "I was baiting them! We do it every day when we interview perps! Get on their level! If we're going to infiltrate we have to convince them that we really want to be there, so I made up a story!"

Oliva went to the kitchen, shaking her head. She kicked off her shoes and poured a glass of wine.

"If you think talking about sex is the worst we will have to do while undercover, you're in for it," Elliot added.

"That night…" Olivia said. "The first all-nighter we ever pulled together…" She turned around to face him, needing to see his eyes when he realizes that he's been caught. "I was wearing a maroon, button-up blouse that I threw out soon after because the top button kept coming undone."

And just like a guilty perp, his face gave him away. Recognition dawned on him when he realized what she was accusing him of and his eyes quickly searched for an excuse.

"Liv, I… um…"

"You what?" she asked. "You fantasize about getting a good fuck from your partner on stressful cases? How 'bout when you're working with Fin and Munch? Do you undress them with your eyes too? Do they 'scream your name through the office' in your fantasies?"

Elliot rubbed the back of his neck as he looked at his feet. "You're a beautiful woman, Liv. I don't have to tell you that."

"So you admit it, then… It's true? That was a fantasy from twelve years ago?"

Elliot eyed her curiously. "Liv, we've flirted with this partner line since we met. Day one. Don't tell me you haven't thought about it!"

"Of course I've thought about it!" Olivia yelled before she could think about what she was saying. She paused, surprised by her own confession before continuing. "I've thought about it, our co-workers joke about all the time, random victims we work with make comments about it! I can't not think about it! But you're my best friend, El! My married best friend and partner! The thoughts end right there!"

"Yeah, well, I'm a guy… Sue me for my vivid imagination," Elliot argued.

"Imagine your wife next time," Olivia countered.

"You know Kathy and I have always had problems, Liv! Don't give me that shit! I'm with you all day, everyday! So yeah, my mind runs a little wild! Can you honestly tell me that in twelve years of 24 hour stakeouts, spending the night in the cribs, experiencing intense, emotional cases together, you haven't once fantasized or dreamed about it beyond the comments people make?"

This time Liv was caught. Elliot pointed his finger and walked toward her when she hesitated. "Ha! I see it! You have thought about it!"

Olivia grabbed his pointed finger and shoved it away. "Fine, I've had dreams, okay?"

"Of what? When?"

"None of your business."

Elliot laughed and placed his hands on his hips. "So we're even then?"

"I've had a few dreams, Elliot. I haven't been fantasizing about screwing you while we work."

"It was hot though, wasn't it?"

Olivia rolled her eyes. "At least you convinced the Swing Set that we're legit," she said. "Go home, El."

He stopped her as she walked to the door to let him out. "I just want to make sure you're really okay with this," he said. And she was glad to see the protective partner in him again so she could stop thinking about him like a horny teen, but she was confused as to what he was talking about.

"With what? The case?" she asked. "Or your gutter-bound mind?"

"We can only hang out in this place for so long without joining them before we're made," he explained.

Olivia nodded when she caught on. "Undercover cops have had to sleep with prostitutes and do drugs to prove themselves. I get it. We can delay it as much as possible but we may eventually have to… play."

"But the minute you're uncomfortable…"

"I'll be fine, El. Go home. Get some sleep. I'll see you tomorrow."

Olivia held the door open as Elliot walked out, but he turned back at the threshold.

"Are we…"

"We're good. Go."

Elliot gave her a half-smile. "Good night, Liv. Sweet dreams!"

One last eye-roll and Olivia shut the door on her married best friend and partner.

Sweet dreams.
