"C'mon hurry up!" A man yelled to a couple as they pulled out their wallets.

Olivia knew she had her gun on her ankle but kept wondering if she should pull it. She looked over at Derek who nodded at Tiffany. Olivia saw him move and reach for his ankle and saw a gun, Derek pulled it out and without missing a beat Olivia pulled hers out and pointed it at him quickly. Tiffany and Derek quickly pointed their guns at her.

"Put your weapon down" Derek said looking at her and keeping his gun aimed at her.

The men heard people talking and turned around and saw Tiffany and Derek pointing their guns at Olivia.

"What the hell is going on!" The men yelled holding his gun and walking over to the bar.

"Were your rivalry. She one of yours?" Tiffany asked keeping her gun aimed at Olivia, while Olivia kept her gun at Derek.

"I'm a cop, put your gun down now," Olivia said glaring at Derek and keeping her gun aimed at him.

"A cop? Ok cop c'mon behind the bar" Derek said.

"Put your weapon down first" Olivia said.

"Who the hell do you think you are? I'm in charge here!" The men yelled at Derek and pointed his gun at him.

"Relax, we get half of the stuff and we wont shoot you in the head. C'mon cop, if you don't want to die come behind the bar," Derek said calmly.

Olivia looked at him and realized she got her self in trouble and knew she had to listen. She stepped on the chair and walked over the bar. Tiffany came over and grabbed her gun and looked around her waist and found her badge and showed it to Derek then put it in her back pocket.

"On the ground" Tiffany instructed pointing to the corner. Olivia did as she was told and sat down.

"You too" Derek said looking at Casey.

"I'm not a cop," Casey said staring at him.

"Just get behind the bar," Derek said pointing the gun at her. Casey nodded and got up and walked over the bar and sat down next to Olivia.

"Good. Now lets negotiate," Derek said looking over at the man.

"Derek what is going on here?" A man said coming out of an office. He was dressed in a very expensive suit.

"Hey boss," Tiffany said smiling and pointing a gun at him.

"What do you think you are doing?" The man asked putting his hands up. The whole club just watched and didn't move from where they were.

"We are intervening with this robbery, since we are robbers ourselves, Mr. Martinez" Tiffany said smiling and grabbing their boss by the tie and pulling him over to the bar.

"We are educated professional thieves," Derek said smiling and whistled. Two men moved threw the crowd with guns in their hands. Both of them looked young as well "These are our colleagues, Bob and lets call him Joe" Derek said smiling and pointed to each man.

"Good evening to all of you" Joe said, he had a British accent.

"Howdy" Bob said, he had a southern accent.

"Fucking foreigners" Derek said chuckling.

"Fuck off" Joe said rolling his eyes.

"Now that we all know each other, I'm Derek, I'm a addicted to sex and guns, and yes I admit I have a problem, I completed step 4 of the program successfully." Derek said smiling. Joe, Bob and Tiffany laughed hysterically as they held their guns up.

"Don't mind him, he likes to have fun when we do our job" Tiffany said smiling and kept her gun pointed at Mr. Martinez

"What job?" Mr. Martinez questioned.

"Stupid bloody Americans" Joe said as he went over to Mr. Martinez and took his expensive tie and put it in his own pocket.

"I'm an American, you got a problem with that partner?" Bob asked looking at him.

"Fuck the Americans, you won the revolutionary war on technicality," Joe said rolling his eyes.

"Here we go" Derek mumbled rolling his eyes,

"Were going to be here all night," Tiffany mumbled looking at the guys and keeping her gun on Mr. Martinez.

"Hey now, we won fair and square, not our fault the British are stupid" Bob defended lowering his gun and walking over to Joe.

"Oh bloody hell, the south also lost the civil war, so you are the fucking Texas idiotic American" Joe said and shoved him. Bob tackled him right away. Derek whistled very loudly, both of them stopped fighting each other.

"You two idiots mind if we finish the job?" Derek asked looking at them get off the ground and held up their guns again.

"No boss" Bob said.

"Good. Now lets negotiate," Derek said looking over at the man.

"I'm not negotiating, this is my job," The man said glaring at him.

"I should warn you I get a little drunk with power holding this fucker" Derek said smiling pointing the gun at him.

"That is very true, he does get stupid when he holds a gun" Tiffany said pointing her gun at the other man. Joe and Bob holding their guns on Mr. Martinez's head.

"C'mon shoot me" The man challenged as he held his gun aimed at Derek.

"You know the feeling of a gun on your head…" Derek said walking over to him and placing his gun on the man's forehead. "That cold feel of steel against your skin, it's almost like when you have sex…" Derek said smiling and cocked the hammer of the gun "And there is orgasm" he said smirking. "BOOM!" Derek yelled out smiling, the man got startled and jumped a little. Derek laughed and moved the gun away from his head.

"Told you he is a crazy mother fucker with that stupid gun" Tiffany said smiling. Joe and Bob just chuckled.

"If you weren't a lesbian I would fuck you Tiffany" Derek said smiling as he took a shot glass on the bar and downed it.

"I'm glad I'm a lesbian when I see you" Tiffany said smiling. Derek just chuckled. Joe and Bob laughed.

"Will you boys take off those ridiculous ski-masks cause they are so '90's" Derek said smiling as he sat on the bar and waved his gun around.

Olivia looked at the way he was holding his gun and could tell he was keeping his finger on the barrel and not on the trigger. The same way she was thought in the academy.

"Put those gun's down and we wont shoot you" The man said aiming his gun at Derek.

"Let's see who will pull the trigger first" Derek challenged and placed his gun on his own head.

"You are out of your mind," The man said staring at him.

"He thinks he's fucking Spartacus when he holds a gun" Tiffany said rolling her eyes as she kept her gun aimed at the other man.

"No baby, I'm Superman" Derek said smiling and moving closer to the man with his gun still on his head.

"Go ahead pull the trigger" The man said staring at him.

"The question is where is it aimed when I do pull it?" Derek asked smiling and pointed his gun at the man's head.

"Look I get your crazy, what kind of deal you want?" The man asked moving away.

"Lets see, I want a blowjob first" Derek said chuckling. Bob and Joe both chuckled "I want half the drugs that are in the basement that you were going to steal and I want all that money you have" Derek said putting his gun down and looking at the man.

"What drugs?" Mr. Martinez asked looking at him.

"Oh c'mon, you run an illegal drug trade blah blah blah, you get the picture. We know about it" Derek said smiling.

"I didn't come to steal any drugs?" The man asked.

"Oh, c'mon, you're an amateur but you didn't come in here just to rip off a bunch of rich mother fuckers" Derek said smiling as he walked back to the bar and glanced at Olivia and Casey and looked away. They both looked at each other confused and then at him.

"We need to kill that cop first" The man said walking over to the bar and looked at Olivia. Olivia's heart just started running faster as she looked at the two men.

"Now is that necessary?" Derek said shaking his head and looking at the man.

"I don't want no pigs as witnesses," The man said glaring at Olivia.

"Why would you say that? Jeez I'm an asshole also but I wouldn't call a woman a pig even if she is a cop, you kiss your mother with that mouth?" Derek asked crossing his arms on his chest while holding the gun.

"Oh god don't bring out the Italian in him when he becomes a gentleman" Tiffany said rolling her eyes.

"You're a lesbian be quiet" Derek said smiling; Tiffany smiled and rolled her eyes. Joe and Bob chuckled and both winked at Tiffany, she smiled and gave them the middle finger.

"I'm not leaving a cop as a witness or we don't make a deal." The man said pointing his gun at Olivia.

"I'll take care of it" Derek said moving his gun out of the way so he can get over the bar.

"You going to kill her?" The man asked lowering his gun.

"Her friend, she is also a cop" Derek said and pulled Casey up.

"I'm not a…" Casey started but Derek squeezed her arm, she said nothing more.

"Are you sure?" The man asked looking at him.

"Tiffany" Derek said.

"Don't ask him that question or he gets very bitchy and pulls the trigger very fast." Tiffany said.

"I'm going to have fun. I'll be back," Derek said smirking and wrapping his arm around Casey's neck. Casey could feel her heart beating hard and wanted to throw up at that point.

"No. Leave her alone!" Olivia yelled out.

"Shut up" Derek yelled angrily as he pulled Casey to the back door and pushed her outside into the alley. Casey slapped him as hard as she could and pushed him away. He grabbed her and pushed her against a wall, she slapped him again. He grabbed her hands and held them.

"Casey stop, I'm a federal agent" Derek whispered holding her hands so she wouldn't slap him again.

"Get off of me now!" Casey yelled as tears started forming in her eyes. Derek let go of her hands but kept her close to the wall.

"Casey, I'm FBI, look," Derek whispered pulling out his badge from his back pocket and showing it to her. She looked at it and could tell he was telling the truth.

"Your undercover?" She whispered.

"Yea, Tiffany and I are both feds. Those two are our backup they are also federal agents. I need you to scream like I'm hurting you, I have to get Olivia out of there" He whispered. Casey nodded and tried to scream as if he doing something to her. Derek moved away since it was loud.

"Good, now I need you to do something for me, I need you get this man" Derek said pulling a card out of his pocket,

"Your Assistant Director?" Casey asked reading the card.

"Yea, call him and tell him that 32B is under mission and we need backup, he'll know what it means," Derek said as he cocked his gun.

"Ok" Casey said nodding.

"One more scream, when I pull the trigger stop immediately" Derek instructed as he held his gun aimed at a wall and standing in front of her. Casey screamed again, Derek shot at the wall two times, Casey stopped right away.

"Your officially dead" Derek said smiling.

"Well thanks for killing me," Casey said smiling.

"Sign your name on this so Olivia knows you're alive cause I don't want her crying and doing something stupid" Derek said handing her a card and a pen. Casey looked at the card.

"Who's Jake Mancini?" She asked looking at him.

"Me, I'm undercover, that's my real name," He said shrugging.

"Well nice to meet you Jake" Casey said smiling as she signed her name on the back of the card and wrote I'm alive

"Stop flirting with me, go get my AD so I can save the world" Jake said smiling. Casey smiled blushing and nodded and started walking out of the alley, he grabbed her and pulled her back and kissed her. Casey completely melted.

"Just in case I don't see you again," He whispered smiling as he released the kiss. Casey smiled and kept her eyes closed as Jake went inside the club again and she quickly ran down the street to find the AD and SVU to get Olivia out of there.
