"Please Astrid," Peter begged, following the junior agent around and nearly on top of her. "Please! We can even wear disguises!"

"It's just not a good idea," Astrid insisted, trying to shake him loose by locking herself in the bathroom.

"I'm not leaving until you say yes," Peter called through the door.

"Peter!" Astrid whined. "Fine! We can go but those undercover outfits better be good because if agent Dunham or Lee sees us there we're dead."

"You won't regret this Astrid!" Peter laughed, leaving her alone for the first time in three hours.

"What won't she regret?" Olivia asked with a smirk.

"Coming over to play Candyland with Walter and I tonight," Peter said quickly.

"That sounds like a lot of fun," Olivia said, biting her lower lip so she wouldn't laugh out loud.

"You'll definitely be missing out," Peter said teasingly, tweaking a blonde lock of hair and meeting her dark green gaze with a flirtatious smile.

"I'm sure I will be," Olivia said honestly.

Peter looked around him to see that they were alone, and stepped into her personal space, lowering his voice. "You'll be careful tonight, right?" Peter caressed her cheek, wanting nothing more than to kiss her.

"I always am," Olivia sighed, leaning into his touch.

"Livia," Peter brushed her lips with his. "Sweetheart, I'm not sure what I'd do without you."

A shiver went down Olivia's spine as she realized just how true his sentiment rang within her. "Peter…"

"Olivia?" A voice called from around the corner, causing them to jerk apart just as Lincoln approached them. "Sorry I wasn't interrupting anything was I?"

"Uh no," Olivia said quickly, blushing. "I'll call you when we're back."

"K," Peter nodded, trying not to be so upset that they couldn't finish their conversation.

Olivia gave him one last look before following Lincoln out of the lab and Peter returned the look with such longing. No way was he going to let her do this case thing tonight alone. He was going to have her back whether she knew it or not.

OPOPOPOPOP

"Is it just me or are my undercover clothes getting sluttier and sluttier?" Olivia sighed, tugging the bottom edge of her black skirt down a little.

"Ummm, no?" Lincoln asked, wincing a little when she glared at him. "Well at least you look hot as hell and I mean that in a purely platonic way."

"Of course you do," Olivia rolled her eyes, knowing he was telling the truth but it probably helped that she looked exactly like the woman he wanted.

"Turns out I'm not very good at lying," Lincoln grinned happily.

"Alright you two," Broyles stepped into the room. "Same drill, but do a better job at blending or another couple may be taken."

They both nodded and did the same trip to the club, both feeling just slightly more at ease since they'd drawn their truce and were civil.

"You ready for this?" Lincoln asked as he unbuckled.

"Yeah, let's get this done." Olivia agreed and they both got out to enter the club.

OPOPOPOPOP

"I can totally tell it's you, Peter," Astrid half laughed as she fixed his shirt collar for him.

"You mean the baseball cap doesn't quite cover it?" Peter joked nervously. It was imperative that Olivia did not see him there.

"Well… just keep your head down," Astrid said, biting her lower lip thoughtfully.

Astrid had dressed in goth-like clothing, with baggy black cargo pants, a black form fitting long sleeved cotton shirt, black fingerless gloves and the darkest make up she owned. She'd even taken the time to braid her hair into small rows so only the back of her hair fluffed out. Peter had gone for the sporty look, with slightly baggier pants than he was used to, but still fit him, a neutral gray t-shirt that hugged only his shoulders and chest a little, and the baseball cap that was meant to hide his face.

"I guess it is what it is," Astrid sighed, grabbing her car keys and heading for the door. "If you get us caught though I'm going to ignore you for the next year."

"Point taken," Peter said seriously.

It wasn't hard getting into the club, but once inside Peter had to cringe. Between the blaring music and the density of people in the room he wasn't sure how people moved, let alone enjoyed their time there. They made their way to the bar where Peter bought them each a drink and found a single seat available. Peter insisted Astrid take it and he could just stand beside her as they did their overt glances around the room to spot the other agents in the room. Peter couldn't help the steady rush of adrenaline that beat through his veins as he perused the room. No wonder he enjoyed working cases with Olivia; he felt so alive, quietly playing a game of "Where's the Bad Guy" while playing it cool. He would definitely have to convince her to allow him out next time with her.

He was just scanning the perimeter of the room again when he saw a flash of golden blonde. Honing in better he realized it was definitely Olivia; Olivia dressed in a black miniskirt and skin tight tank top being pressed to the wall by agent Lee and they were definitely not just discussing the weather. He had her pinned with his hips as he thrust his tongue down her throat while his hands wondered her curves. One hand was gripping her thigh, pulling her closer up to his height while his other hand wound its way into her hair to get better access to her mouth. Peter's blood went from ice to boiling in a matter of seconds. What was that agent thinking making out with his girl?

Before Peter could comprehend what he was doing he was pushing through the crowd toward the two agents who seemed not to notice him until he was pulling Lincoln back from Olivia and then throwing a punch at his face before Olivia could react.

"Peter!" Olivia gasped as he pulled his fist back for another strike. She made a dive for his arm and wrenched it back before he could hit Lincoln again. "What are you doing here?"

Peter paused for a moment, temporarily stalled from his rage at the look of worry, anger, and fear crossing her dark green eyes. Two bouncers found their way to the trio and pulled Peter off Lincoln.

"That's it, you can't stay here," one of the men said gruffly and Peter struggled at first, wanting to talk to Olivia; to ask her what she had been doing making out with Lincoln when they were supposed to have something together. The bouncers set Peter down outside with strict instructions not to return. Astrid came rushing out seconds later, muttering under her breath and pushing him along.

"Let's just get you home," Astrid said, leading them back to the car.

Peter was still seeing a hazy red at having seen Olivia and Lincoln all over each other and allowed Astrid to drop him off at the house. Once there he debated between a steaming hot shower or a long run in hopes of burning the image from the club out of his brain at least for the night. He quickly decided on the shower, making sure to turn his phone off so he wouldn't have to worry about any calls; he just wasn't in the mood. Stripping down, Peter stepped into the shower and under the hot spray of the nozzle. Tossing his head back he let the hot water wash across his face and make smooth trailed down his body.

Peter clenched and unclenched his fists, fighting the urge to throw punches at the tiled wall to let the built up aggression out of him but he only growled and ran his fingers through his hair to wash it. He stayed under the water's pressure for a good twenty minutes before he finally dragged himself out of the shower and got dressed into a pair of pajama pants. He was about to go find a book to read and hopefully distract him when there was a knock on the front door. Not wanting to go upstairs to find a shirt only to come back down he went straight for the door and opened it without looking to see who it was.

"You belong with me," Olivia said in a rush, standing in his doorway dressed in jeans, t-shirt, and a leather jacket.

He honestly hadn't thought she'd come to see him, but there she was; wind blowing her blonde hair back with her green eyes glowing in determination.

"You sure you're talking to the right guy there sweetheart?" Peter asked coldly.

"I said that to you once," Olivia said, unperturbed by his response. "You belong with me and I belong with you."
